Referring to fig. 2, fig. 2 is a flowchart of a first embodiment of a picture adjusting method of a display device according to the present invention, in this embodiment, the picture adjusting method of the display device includes the following steps:
step S10: acquiring distance information between the eyes of a display equipment wearer and lenses on a lens barrel of the display equipment;
in this embodiment, the display device may include a head-mounted display device, such as a head-mounted display device based on VR (Virtual Reality), AR (Augmented Reality), or holographic technology, or other display devices that need to adjust picture display parameters according to distance information. The display equipment is provided with a human body proximity sensor for acquiring relative position information of a human body of a display equipment wearer and the head-mounted display equipment, and the distance between the eyes (especially eyeballs) of the display equipment wearer and the lenses on the display equipment lens barrel can be determined according to the relative position information, so that the distance information between the eyes of the display equipment wearer and the lenses on the display equipment lens barrel is acquired. Based on the human face difference, the proximity sensor can be one, for example, the proximity sensor can be arranged on the display device at a position opposite to the middle position of two human eyes to acquire the distance information between the eyes of the wearer of the display device and the lenses on the lens barrel of the display device; the distance between two glasses of different wearers and the display equipment can be respectively collected, so that the situation that one eye of part of wearers has visual disorder is prevented, and the distance information between the eye of the wearer of the display equipment and the lens on the lens cone of the display equipment can be more accurately acquired. On the basis, the number and the positions of the proximity sensors can be set or started according to specific application conditions, so that the display adjustment parameters of the picture of the display device can be more accurately determined according to the acquired distance information, and the display parameters of the display device can be adjusted according to the display adjustment parameters, so that the adjusted display picture is matched with the display area in the visual range of the wearer.
Step S20: determining display adjustment parameters of a display device picture according to the distance information;
when the distance between the eyes of the wearer and the lenses on the lens barrel is different, the display area in the visual range of the corresponding wearer is different, and when the display area in the visual range is changed, the display adjusting parameters of the display equipment picture corresponding to the current wearing distance need to be determined according to the distance information between the eyes of the wearer and the lenses on the lens barrel, and then the display parameters of the display equipment are adjusted according to the display adjusting parameters, so that the display picture of the display equipment is matched with the visual ranges corresponding to different distances. The display adjustment parameter is, particularly, when a display screen of a display device needs to be adjusted, an adjustment parameter that the display screen needs to be adjusted, and if the size of the display screen needs to be adjusted, a corresponding adjustment ratio needs to be determined, so that the display adjustment parameter at least includes a screen scaling parameter, and a corresponding adjustment type and an adjustment value can be determined according to the screen scaling parameter, where the adjustment type may be an enlargement adjustment or a reduction adjustment, and correspondingly, the adjustment value may be a magnification factor or a reduction factor; the display parameters of the display device refer to parameters corresponding to a display picture to be output, which are used by the display device, for example, a display area of the display picture to be output, a resolution corresponding to the output of the display picture in the display area, and the like. Therefore, before adjusting the display parameters of the display device according to the display adjustment parameters, in order to determine the display adjustment parameters of the display device picture, a reference display area in a visual range and a reference distance corresponding to the reference display area in the visual range may be determined, and then the display adjustment parameters of the display device picture may be determined according to the relationship (e.g., size relationship, ratio relationship, etc.) between the distance information between the eyes of the wearer and the lenses on the lens barrel and the reference distance; of course, the display area in the visual range corresponding to the distance information may be determined according to the distance information, and then the display adjustment parameter of the display device picture may be determined according to the relationship (e.g., size relationship or ratio relationship, etc.) between the determined display area in the visual range and the reference display area in the visual range. The reference display area in the visual range may be a display area when an image in the visual range of a wearer is most clear, or a maximum display area which can be viewed on a display screen of the display device in the visual range of the wearer, and the like, and the reference display area in the visual range may be specifically set according to actual conditions.
Step S30: adjusting display parameters of the display equipment according to the display adjustment parameters so as to enable the adjusted display picture to be matched with a display area in the visual range of the wearer;
and after the display adjusting parameters are determined, adjusting the display parameters of the display equipment according to the display adjusting parameters so as to enable the adjusted display picture to be matched with a display area in the visual range of the wearer. The display parameters of the display device are adjusted according to the display adjustment parameters, the adjustment type and the corresponding adjustment value are determined according to the display adjustment parameters, and then the display parameters of the display device are adjusted according to the adjustment type and the corresponding adjustment value, so that the adjusted display picture is matched with the display area in the visual range of the wearer. Specifically, if it is determined that the display device needs to be enlarged and adjusted according to the adjustment of the display adjustment parameter, determining a corresponding enlargement factor according to the display adjustment parameter, determining a display size of an enlarged display device picture according to the enlargement factor and a reference display area within a visual range, and adjusting the display parameter of the display device according to the determined display size to match the adjusted display picture with a display area within the visual range of a wearer, thereby ensuring that the complete display picture is presented to the wearer within the visual range of the wearer; and if the display equipment needs to be reduced and adjusted according to the adjustment of the display adjustment parameters, determining a corresponding reduction multiple according to the display adjustment parameters, determining the display size of a reduced display equipment picture according to the reduction multiple and a reference display area in a visual range, and adjusting the display parameters of the display equipment according to the determined display size so as to enable the adjusted display picture to be matched with the display area in the visual range of a wearer. The display area in the visual range of the wearer refers to a display area on a display screen viewable by the wearer through a tube lens of the display device at the current wearing distance.
According to the embodiment, the distance information between the eyes of the display equipment wearer and the lenses on the lens barrel of the display equipment is acquired, the display adjusting parameters of the picture of the display equipment are determined according to the distance information, and then the display parameters of the display equipment are adjusted according to the display adjusting parameters, so that the adjusted display picture is matched with the display area in the visual range of the wearer, the user can have the same picture experience feeling under different wearing distances, the situation that different clear and complete display pictures are output to the user due to wearing problems or individual difference problems is avoided, and the reliability of picture output and the picture display effect are improved.
Referring to fig. 3, fig. 3 is a flowchart of a second embodiment of a picture adjusting method of a display device according to the present invention, in this embodiment, the picture adjusting method of the display device includes the following steps:
step S11: acquiring distance information between the eyes of a display equipment wearer and lenses on a lens barrel of the display equipment;
step S12: determining a display area within the visual range of the wearer according to the distance information;
step S13: determining display adjustment parameters of the display equipment picture according to a display area in the visual range of the wearer and a preset threshold display area;
step S14: and adjusting the display parameters of the display equipment according to the display adjusting parameters so as to enable the adjusted display picture to be matched with a display area in the visual range of the wearer.
In this embodiment, after obtaining distance information between an eye of a display device wearer and a lens on a lens barrel of the display device, a display area within a visual range of the display device wearer is determined according to the distance information, then a display adjustment parameter of a picture of the display device is determined according to the display area within the visual range of the wearer and a preset threshold display area, and the display parameter of the display device is adjusted according to the display adjustment parameter, so that the adjusted display picture is matched with the display area within the visual range of the wearer. Generally, display areas in a visual range of different wearers are different when the display device is worn by the different wearers, in order to adapt to visual requirements of the different wearers as much as possible, a threshold display area is determined according to characteristics of different human bodies, before the display area in the visual range of the wearer is determined according to the acquired distance information, the threshold display area is generally used as a default display area of a system, that is, the display device displays a picture in the threshold display area by default, that is, the picture of the display device displays the picture in a resolution ratio matched with the threshold display area by default. Thus, in this embodiment, the preset threshold display area refers to a maximum display area that is visible in a visual range of different wearers of the display device, which is set by default. Therefore, according to the relationship between the display area in the visual range of the wearer and the preset threshold display area, the display adjustment parameters of the picture of the display device can be determined, the picture display size of the display device can be determined according to the display adjustment parameters, and the display parameters of the display device are adjusted according to the determined picture display size, so that the adjusted display picture is matched with the display area in the visual range of the wearer to adapt to the visual demands of different wearers or adapt to the visual demands of the same wearer at different distances.
In a specific embodiment, the display adjustment parameter of the display device frame may be determined according to a relationship between the area of the display region in the visual range of the wearer and the area of the preset threshold display region. Specifically, the area of the display area in the visual range may be compared with the area of the preset threshold display area to obtain an area ratio, a display adjustment parameter of the display device picture is determined according to the area ratio, whether the adjustment type is an enlargement adjustment or a reduction adjustment is determined according to the display adjustment parameter, a corresponding enlargement factor or a corresponding reduction factor is determined, and then the display parameter is adjusted according to the enlargement factor or the reduction factor corresponding to the adjustment type, so that the adjusted display picture is matched with the display area in the visual range of the wearer. Before comparing the area of the display area in the visual range with the area of the preset threshold display area to obtain the area ratio, the area of the display area of the wearer in the visual range needs to be determined. In an embodiment, the area of the display area in the visual range of the wearer can be determined according to the distance information between the eyes of the wearer of the display device and the lenses on the lens barrel, the distance information between the lens barrel and the display screen, and the radius of the lens barrel. Specifically, the distance information between the eyes of the wearer and the display screen can be determined according to the distance information between the eyes of the wearer and the lenses on the lens barrel and the distance information between the lens barrel and the display screen of the display device (the distance between the eyes of the wearer and the display screen is the sum of the distance between the eyes of the wearer and the lenses on the lens barrel and the distance between the lenses on the lens barrel and the display screen of the display device), the distance ratio between the eyes of the wearer and the display screen and the distance between the eyes of the wearer and the lenses on the lens barrel can be determined according to the distance information between the eyes of the wearer and the display screen and the distance between the eyes of the wearer and the lenses on the lens barrel, then taking the product of the distance ratio and the radius of the lens on the lens cone as the radius of the display area in the visual range, and then calculating the area of the display area in the visual range by utilizing a circle area formula according to the radius of the display area in the visual range.
Specifically, as shown in the schematic diagram of calculating the display area in the visual range of the wearer in fig. 4, it can be seen that the distance between the eye of the wearer and the lens on the lens barrel is X, the distance between the lens on the lens barrel and the display screen is X' (fixed value), and the lens area of the lens barrel is S (fixed value). The radius of the lens on the lens barrel is r (fixed value), and the display area S 'in the visual range of the wearer (in this case, the radius of the display area in the visual range is r'). As is apparent from the change in the eye position of the wearer in the figure, when the eye of the wearer is away from the lens on the lens barrel, the display area in the visual range of the wearer is S "(in this case, the radius of the display area in the visual range is r ″), and obviously r ″.<r' is, S<S', namely, the farther the distance between the eyes of the wearer and the lenses on the lens cone is, the smaller the display area which can be observed in the visual range of the wearer is, and conversely, the closer the distance between the eyes of the wearer and the lenses on the lens cone is, the larger the display area which can be observed in the visual range of the wearer is, if the included angle between the straight line where the centers of the eyes of the wearer and the display area in the visual range are located and the straight line where any point on the circumferences of the eyes of the wearer and the display area in the visual range is located is α, the included angle between the straight line where the centers of the eyes of the wearer and the
And is
Then the equivalence relation between the two can be obtained
So that when the distance between the eyes of the wearer and the lens on the lens barrel is X, the radius r' of the display area in the visual range of the wearer is X
Since the display area viewable by the wearer of the circular lens through the lens barrel is a circular area, the area of the display area in the visual range of the wearer can be obtained according to the area formula of the circle
In another embodiment, to avoid the false adjustment and improve the adjustment efficiency, before determining the display adjustment parameter of the display device picture according to the display area within the visual range of the wearer and the preset threshold display area, it is determined whether the display area within the visual range of the wearer is consistent with the preset threshold display area, if not, it is determined that the display parameter of the display device needs to be adjusted, at this time, the display adjustment parameter of the display device picture can be determined according to the display area within the visual range of the wearer and the preset threshold display area, and then the display parameter of the display device is adjusted according to the display adjustment parameter, for example, when the display area within the visual range of the wearer exceeds the preset threshold display area, the display picture of the display device needs to be enlarged and adjusted, at this time, determining a corresponding magnification according to a display area in the visual range of the wearer and the preset threshold display area, and adjusting display parameters of the display equipment according to the magnification; when the display area in the visual range of the wearer is smaller than the preset threshold display area, the display picture of the display equipment needs to be reduced and adjusted, a corresponding reduction multiple is determined according to the display area in the visual range of the wearer and the preset threshold display area, and the display parameters of the display equipment are adjusted according to the reduction multiple. On the other hand, if the display area in the visual range of the wearer is consistent with the preset threshold display area, it is determined that the display parameters of the display device do not need to be adjusted, and at this time, the display parameters corresponding to the preset threshold display area are directly used for displaying the picture.
In another embodiment, after determining the display adjustment parameter of the display device picture according to the area ratio of the display area in the visual range of the wearer to the preset threshold display area, the adjusting the display parameter of the display device according to the display adjustment parameter to match the adjusted display picture with the display area in the visual range of the wearer includes: adjusting the display parameters of the display equipment according to the display adjustment parameters to obtain adjusted display parameters; and carrying out scaling processing on the resolution of the display picture according to the adjusted display parameters and the area ratio so as to enable the processed display picture to be matched with a display area in the visual range of the wearer. If the area of the display area in the visual range of the wearer is a, and the area of the preset threshold display area is b, determining that the display adjustment parameter of the picture of the display device is ba, and since the display parameter (e.g. resolution) set by the display device is the resolution adapted to the preset threshold display area before adjusting the display parameter of the display device, that is, the corresponding resolution m when the preset threshold display area displays the clearest picture, setting the display parameter (e.g. resolution) n of the display device to be the resolution m corresponding to the size of the display area in the visual range of the current wearer at the current wearing distance
Then, after the display parameters of the display device are adjusted according to the display adjustment parameters to obtain the adjusted display parameters, the resolution of the display picture to be displayed is adjusted to be equal to that of the display deviceThe resolution ratio of the display picture is required to be scaled according to the area ratio according to the adjusted display parameters until the resolution ratio of the display picture to be displayed is adjusted to be consistent with the display parameters of the display device, and the processed display picture can be matched with the display area in the visual range of the wearer, so that the complete picture can be output to the wearer in the display area in the visual range of the wearer, and the definition of the display picture output to the wearer is ensured. The process of scaling the resolution of the display picture according to the adjusted display parameters according to the area ratio may be to scale the resolution by a corresponding scaling algorithm according to the area ratio, the arrangement and the positions of the horizontal and vertical pixels of the display picture, and the like, and the scaling algorithm is not limited and may be selected according to specific application requirements.
The embodiment obtains the distance information between the eyes of the wearer of the display device and the lenses on the lens barrel of the display device, so as to determine the display area in the visual range of the wearer according to the distance information, then determining display adjustment parameters of the display equipment picture according to the display area in the visual range of the wearer and the preset threshold display area, and adjusting the display parameters of the display device according to the display adjustment parameters to match the adjusted display picture with the display area in the visual range of the wearer, thereby adjusting the display picture of the display device according to the relation between the display area in the visual range and the preset threshold display area, therefore, different users or the same user can feel the same complete and clear picture display effect under different wearing distances, and the picture output stability and the picture display effect of the display equipment are improved.
Referring to fig. 5, fig. 5 is a flowchart of a picture adjusting method of a display device according to a third embodiment of the present invention, in this embodiment, the picture adjusting method of the display device includes the following steps:
step S21: acquiring distance information between the eyes of a display equipment wearer and lenses on a lens barrel of the display equipment;
step S22: judging whether the distance between the eyes of the wearer and the lens on the lens barrel is larger than a first distance threshold and smaller than a second distance threshold or not according to the distance information;
step S23: if the distance between the eyes of the wearer and the lens on the lens barrel is smaller than a first distance threshold or larger than a second distance threshold, determining display adjustment parameters of the picture of the display equipment according to the distance information;
step S24: and adjusting the display parameters of the display equipment according to the display adjusting parameters so as to enable the adjusted display picture to be matched with a display area in the visual range of the wearer.
In this embodiment, after the distance information between the eye of the wearer of the display device and the lens on the lens barrel of the display device is acquired, since the distance information between the eye of the wearer of the display device and the lens on the lens barrel of the display device has a corresponding relationship with the display area within the visual range of the wearer, whether the display frame of the display device needs to be adjusted can be determined according to the relationship between the display area within the visual range of the wearer and the preset threshold display area, and on this basis, before the display adjustment parameter of the display device frame is determined according to the acquired distance information, whether the display frame of the display device needs to be adjusted can be directly determined according to the distance information between the eye of the wearer of the display device and the lens on the lens barrel of the display device. Specifically, a reference distance corresponding to the threshold display area may be preset, and then it is determined whether a distance between the eye of the wearer and the lens on the lens barrel is within a preset distance range (greater than the first distance threshold and less than the second distance threshold) of the reference distance. When the distance between the eye of the wearer and the lens on the lens barrel is within a preset distance range of the reference distance, namely the distance between the eye of the wearer and the lens on the lens barrel is greater than a first distance threshold and smaller than a second distance threshold, the display area within the visual range of the wearer can be regarded as being consistent with the display area of the preset threshold, and at the moment, the display picture of the display equipment does not need to be adjusted; the display picture of the display device needs to be adjusted only when the distance between the eyes of the wearer and the lenses on the lens barrel exceeds a preset distance range of the reference distance, namely the distance between the eyes of the wearer and the lenses on the lens barrel is smaller than a first distance threshold or larger than a second distance threshold. Specifically, since the distance between the eye of the wearer and the lens on the lens barrel is in inverse proportion to the display area visible by the wearer in the visual range, if the distance between the eye of the wearer and the lens on the lens barrel is smaller than a first distance threshold, it is determined that the display image of the display device needs to be magnified and adjusted, and at this time, the magnification adjustment parameter of the display image needs to be determined according to the distance information, so that the display parameter of the display device is adjusted according to the magnification adjustment parameter; if the distance between the eyes of the wearer and the lens on the lens barrel is larger than a second distance threshold, it is determined that the display picture of the display device needs to be reduced, and at this time, a reduction adjustment parameter of the display device picture needs to be determined according to the distance information, so that the display parameter of the display device is adjusted according to the reduction adjustment parameter. The first distance threshold is a preset distance threshold larger than a reference distance within a certain range, the second distance threshold is a preset distance threshold smaller than the reference distance within a certain range, and the first distance threshold is smaller than or equal to the second distance threshold.
In this embodiment, by obtaining distance information between an eye of a display device wearer and a lens on a lens barrel of the display device, determining whether to adjust a display parameter of the display device according to the distance information, determining a display adjustment parameter of a picture of the display device according to the distance information when the display parameter of the display device needs to be adjusted, and then adjusting the display parameter of the display device according to the display adjustment parameter, so that the adjusted display picture is matched with a display area within a visual range of the wearer, thereby directly determining whether to adjust the display parameter of the display device according to the distance information, and directly performing corresponding parameter adjustment according to the distance information when adjustment is needed, not only can improve a picture display effect and reliability of picture output, but also can improve processing efficiency of display parameter adjustment, the processing procedure is simplified.
