detailed description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

Fig. 1 is a flow chart of a method for video fill light according to an exemplary embodiment. The video fill light method can be applied to smart devices. For example, the smart device may be a mobile phone, a tablet computer, a PC, a notebook computer, and other terminals with a video chat function. The video supplement light method may include the following steps:

In step 101, when a smart device is used for video chatting, it is judged whether it is necessary to supplement light to a camera of the smart device.

During video chatting, if the environment of the local user is relatively dark, for example, at night or in an environment with insufficient light such as cloudy days, the image quality of the local user will be poor, mainly because the camera used to capture the local user’s image The camera cannot capture enough light. To this end, the present disclosure provides a solution for supplementing video through a display screen of a smart device without resorting to an external light source. As an example, the camera in the present disclosure may be a front camera of a smart device.

When the local user conducts video chat through the smart device, relevant information can be collected, and according to the collected information, it can be judged whether it is necessary to use the disclosed solution for supplementary light. For example, in the present disclosure, at least the following two example solutions can be used to determine whether it is necessary to supplement the light of the camera of the smart device.

Example Solution 1: Obtain the light intensity of the environment where the local user is located, and determine whether the light intensity is lower than a preset light intensity; if the light intensity is lower than the preset light intensity, then determine that the camera needs to be Make fill light.

In this example, the relevant information is reflected in the light intensity of the environment where the local user is located. Understandably, after the local user starts the video chat function, the smart device can automatically acquire the light intensity of the current environment, for example, the light intensity can be collected by a light sensor of the smart device.

If the acquired light intensity is lower than the preset light intensity, it can be determined that the camera needs to be supplemented with light to ensure that the camera can collect enough light, thereby improving the image quality of the local user image captured and presented by the camera. Optionally, if the acquired light intensity is not lower than the preset light intensity, it can be determined that there is no need to add light to the camera, that is, the light currently collected by the camera can ensure the image quality of the local user's image.

As an example, it is possible to pre-statize the requirements of most users on the user's image quality during a video call, determine the preset light intensity that matches the requirements, and configure it in the smart device in the form of a default value. Alternatively, when the user is making a video call, the user may be asked about the user's requirements for image quality, and an appropriate preset light intensity for the user may be determined according to the user's requirements. Furthermore, the preset light intensity can be set in combination with the above two examples. For example, based on the default value, the user can adjust the default value to the preset light intensity that matches the user's own use requirements. The present disclosure may not limit the manner of setting the preset light intensity.

Example solution 2: acquire the picture quality of the video of the local user, and determine whether the picture quality is lower than the preset picture quality; if the picture quality is lower than the preset picture quality, determine that the camera needs to be Make fill light.

In this example, the relevant information is embodied as the picture quality of the local user's video. Understandably, after the local user activates the video chat function, the smart device can automatically acquire the picture quality of the current video.

If the acquired image quality is lower than the preset image quality, it can be determined that the camera needs to be supplemented with light to ensure that the camera can collect enough light, thereby improving the image quality of the local user image captured and presented by the camera. Optionally, if the acquired image quality is not lower than the preset image quality, it may be determined that it is not necessary to supplement the camera with light.

Similar to the scheme of setting the preset light intensity above, when setting the preset image quality, the image quality requirements of most users can be determined as the preset image quality, and configured in the smart device as a default value; Alternatively, the user's own requirements for image quality can also be determined as the preset image quality; moreover, the above two examples can also be combined, and the user can adjust the default value to match the user's own requirements on the basis of the default value. Use a preset quality that matches the requirements. The present disclosure may not limit the manner of setting the preset image quality.

In step 102, if it is determined that the camera needs to be supplemented with light, a supplementary light area and an image area are determined on the display screen of the smart device, and the supplementary light area is used to supplement light for the camera, The image area is used to display the image of the local user and the image of the peer user, and the brightness of the supplementary light area is higher than the brightness of the image area.

When it is determined in step 101 that the camera needs to be supplemented with light, two areas can be divided from the display screen, one is a supplementary light area for supplementing light for the camera, and the other is an image area for displaying user images. Wherein, in order to achieve the supplementary light effect, the brightness of the supplementary light area should be higher than the brightness of the image area.

It can be understood that if the local user starts the video chatting function and the environment is relatively dark, then when the disclosed solution is used to start the video chatting, the display screen includes a fill light area and an image area. If the environment becomes dark during a video chat, for example, when video chatting at night, from a room with lights on to a room without lights, when the video chat starts, that is, when the local user is in the room with lights on, The display screen includes the image area, but when it is determined that the camera needs to be supplemented with light, that is, when the local user enters a room where the light is not turned on, the display screen can be switched to include the fill light area and the image area.

As an example, the supplementary light area and the image area can be determined from the display screen through the following scheme: shrinking the original image area on the display screen to obtain the image area, and removing all The area outside the image area is determined as the supplementary light area.

Fig. 2 is a schematic diagram showing switching of display screens when a smart device performs video fill light according to an exemplary embodiment. It can be understood that when supplementary light is required, the original image area 201 on the display screen can be reduced, for example, the original image area can be reduced according to the ratio of the display screen, and the remaining area of the display screen can be filled with a bright color. The image area 202 and the supplementary light area 203 shown in FIG. 2 are formed, and the brightness of the supplementary light area is higher than the brightness of the image area.

To sum up, when the local user makes a video call, you can first determine whether the current environment of the local user will affect the image quality of the local user's video, that is, whether it is necessary to fill in the camera light, and if it is determined that the camera needs to be supplemented If there is no light, the display screen of the smart device can be divided into a supplementary light area and an image area, and the brightness of the supplementary light area can be appropriately increased to make the supplementary light area play a lighting role, so as to ensure that the camera can collect enough light and improve video calls. The image quality of the local user image presented during the process.

In a possible implementation manner, in order to improve the flexibility of the disclosed solution, a shape adjustment instruction may be acquired, and the shape and/or position of the supplementary light area may be adjusted according to the shape adjustment instruction. That is to say, the user at the local end can adjust the shape and/or position of the supplementary light area through the shape adjustment command according to his actual use needs, so as to realize the personalized supplementary light of the camera, which can not only improve the flexibility of the disclosed solution, but also combine Carrying out supplementary light in actual conditions also helps to improve the supplementary light effect of the disclosed solution.

As an example, when the solution of the present disclosure is used for supplementary light, the operation action of the local user may be monitored, and the shape and/or position of the supplementary light area may be adjusted according to the operation action.

Alternatively, when the user at the local end clicks the display screen, a series of function buttons can be called out. For example, the function buttons can be shape adjustment buttons, brightness adjustment buttons, color adjustment buttons, etc., and when the user at the local end clicks the shape adjustment button , to display the preset shape to the local user.

Example solution 2, the operation action may be a dragging action of the local user, and the shape adjustment instruction may be an instruction formed after recognizing the local user's gesture action on the fill light area.

Optionally, the gesture action may be a position adjustment action, for example, dragging the supplementary light area from the first position to the second position of the display screen. Fig. 3 is a schematic diagram showing position adjustment of a supplementary light area according to an exemplary embodiment. Wherein, the first position is below the display screen, and the second position is above the display screen. The local user can adjust the fill light area 301 from the bottom of the display screen to the top of the display screen by dragging and dropping, as shown in FIG. 3 It can be seen from the illustration that the image area 302 may change with the adjustment of the supplementary light area 301 . Alternatively, the gesture action may also be a zooming action, for example, performing a zoom-in operation on the supplementary light area to increase the space occupied by the supplementary light area, which helps to increase the intensity of light collected by the camera.

Example solution 3, the operation action can change the display screen status for the local user, for example, the display screen status can be landscape or portrait status, and the shape adjustment instruction can be adjusted to landscape screen status when the screen is detected.

Optionally, when it is detected that the display screen is in a landscape orientation, the position of the supplementary light area can be adjusted so that the supplementary light area is located at the end of the display screen close to the camera. Fig. 4 is a schematic diagram showing position adjustment of a supplementary light area according to an exemplary embodiment. When the local user adjusts the smart device from the vertical screen state to the horizontal screen state, the supplementary light area 401 is adjusted from the bottom of the display screen to the left side of the display screen, and as shown in Figure 4, the image area 402 may be supplemented The adjustment of the light area 401 varies. Make the fill light area as close as possible to the position of the camera, which will help the camera collect the light in the fill light area and improve the image quality of the local user.

The disclosed scheme does not limit the shape adjustment scheme of the supplementary light area.

In a possible implementation manner, in order to improve the flexibility of the disclosed solution, a brightness adjustment instruction may be obtained, and the brightness of the supplementary light area may be adjusted according to the brightness adjustment instruction. That is to say, the local user can adjust the brightness of the supplementary light area through the brightness adjustment command according to their actual use needs, so as to realize the personalized supplementary light of the camera. The light also helps to enhance the light fill effect of the disclosed scheme.

As an example, when using the solution of the present disclosure to perform supplementary light, the operation action of the user at the local end may be monitored, and the brightness of the supplementary light area may be adjusted according to the operation action. For example, the operation action may be that the local user clicks on the display screen, and the brightness adjustment instruction may be an instruction generated after obtaining a brightness value input by the local user.

Optionally, a dedicated brightness adjustment button can be set on the display screen, and when the local user clicks the brightness adjustment button, a brightness adjustment progress bar will be called out, and the local user can input the brightness value by dragging the progress bar. Alternatively, when the local user clicks the brightness adjustment button, a brightness adjustment input box may be called out, and the local user may input a brightness value in the input box.

Optionally, when the local user clicks on the display screen, a series of function buttons can be called out. For example, the function buttons can be shape adjustment buttons, brightness adjustment buttons, color adjustment buttons, etc., and when the local user clicks the brightness adjustment When the button is pressed, the brightness adjustment progress bar or the brightness adjustment input box is called out to obtain the brightness value input by the local user.

The disclosed scheme does not limit the brightness adjustment scheme of the supplementary light area.

In a possible implementation manner, in order to improve the flexibility of the disclosed solution, a color adjustment instruction may be obtained, and the color of the supplementary light area may be adjusted according to the color adjustment instruction. That is to say, the local user can adjust the color of the supplementary light area through the color adjustment command according to their actual use needs, so as to realize the personalized supplementary light of the camera. The light also helps to enhance the light fill effect of the disclosed scheme.

As an example, when using the solution of the present disclosure to perform supplementary light, the operation action of the local user may be monitored, and the color of the supplementary light area may be adjusted according to the operation action. For example, the smart device saves the preset color of the supplementary light area, the operation action can be that the local user clicks on the display screen, and the color adjustment instruction can select a suitable color from the preset colors for the local user.

Optionally, a dedicated color adjustment button can be set on the display screen, and when the local user clicks the color adjustment button, the preset color is displayed to the local user for the local user to select a suitable color from. Alternatively, when the local user clicks the display screen, a series of function buttons can be called out. For example, the function buttons can be shape adjustment buttons, brightness adjustment buttons, color adjustment buttons, etc., and when the local user clicks the color adjustment button , to display the preset color to the local user.

For example, the preset color may be a solid color, such as white, yellow, etc.; or, the preset color may also include background shading, which is not limited in the present disclosure.
