Exemplary, as shown in fig. 10, a schematic diagram of a calibration process of a calibration system according to an embodiment of the present application is provided.

In some embodiments, when a user desires to correct a color of a displayed user interface of the display 275 of the display device 20, the user may input a user command through a Graphical User Interface (GUI) displayed on the display 275 to cause the display device 20 to turn on the correction function. Further, the user input interface receives a user command through a Graphical User Interface (GUI), in response to which the display device 20 turns on the correction function, i.e., the correction function is started.

In some embodiments, the user may also issue a user command to the display device 20 via the remote control to initiate the correction function, which in turn is received by the user interface 265. In response to the user command, display device 20 initiates a correction function.

In some embodiments, after the display device 20 turns on the correction function, the controller 250 may control the display 275 to display a first prompt for prompting the user to place the test device 10 in a position where display characteristic data of the display 275 can be collected, for example, prompting the user to place the test device 10 in the center of the screen of the display 275. For example, as shown in fig. 11, the content of the first prompt displayed on the display 275 may be "please place the test device at the center of the screen".

In some embodiments, where the test apparatus 10 is a camera, the controller 250 may further control the display 275 to display second prompt information before controlling the display 275 to display the first prompt information, where the second prompt information is used to prompt the user to connect the camera with the display apparatus 20 through the USB connection line. For example, the content of the second prompt displayed on the display 275 may be "please connect the test device to the display device through a USB connection line".

In some embodiments, after the user places the test device in a position where the display characteristic data of the display 275 can be collected, the display device 20 receives the display characteristic data from the display 275 sent by the test device 10.

In some embodiments, after display device 20 receives display characteristic data from display 275 sent by test device 10, controller 250 controls display 275 to display a graphical user interface for the user to input the desired calibration target. The ideal correction target may be user-defined, or a plurality of correction targets may be pre-stored in the display device 20, and the controller 250 controls the display 275 to display the plurality of correction targets on the image user interface, and the user selects the ideal correction target from the plurality of correction targets.

After receiving the ideal correction target input by the user, the display device 20 performs a data test according to the display characteristic data of the display 275 sent by the test device 10 and the ideal correction target input by the user, and the controller 250 determines whether the color and brightness of the current display 275 need to be corrected.

In the event that it is determined that no correction is required to the chromaticity and/or luminance of the current display 275, the controller 250 issues a third prompt message for prompting that no adjustment is currently required.

For example, the controller 250 may control the display 275 to display the third hint information, and the third hint information displayed by the display 275 may be "correction is not currently required".

In the event that it is determined that correction of the color and brightness of the current display 275 is required, the controller 250 automatically corrects based on algorithms of automatic gamma, automatic white balance, color model (hue saturation value, HSV), 3DLUT, etc.

In some embodiments, the controller 250 performs precondition-based settings as needed, such as controlling the zone light LD functionality off, controlling the dynamic contrast DCI functionality off, etc., before performing the auto-correction. It should be noted that, the above-mentioned control of the LD function to be turned off and the control of the DCI function to be turned off are only exemplary, and the automatic correction may be performed when the LD function is turned on and the DCI function is turned on, which is not limited in the embodiment of the present application.

In some embodiments, after the auto-correction is completed, the pre-conditions after the setting are restored to the original setting.

In some embodiments, the ROM 252 stores therein a test chart card in advance, and after the display device 20 turns on the auto-correction function, the ROM 252 transmits the test chart card to the controller 250 so that the controller 250 performs auto-correction according to the test chart card.

HSV is obtained by the following formula:

max=max (R, G, B) formula (1)

min=min (R, G, B) formula (2)

V=max/255 formula (5)

Wherein H is hue, S is saturation, and V is brightness.

For the display characteristic data of the display 275, Δe may be calculated according to CIE2000, where the calculation process is rgb→xyz→la→b×c _ab →ΔL′ΔC′ _ab ΔH′ _ab Can respectively calculate brightness difference, chroma difference and chromatic phase difference, and at the same time needs to calculate S _L 、S _H And S is _C The specific calculation process of the equal weight coefficient can be shown by the following formula:

wherein L represents brightness, a represents red-green color difference, b represents blue Huang Secha, a ^* Represents a position (a) between red/magenta and green ^* A negative value indicates green and a positive value indicates magenta), b indicates a position between yellow and blue (b indicates blue and a positive value indicates yellow), C _ab For the psychological degree of colour,for two colours to be calculated C _ab Is a mean arithmetic value of (c). H'. _ab For psychological hue angle, G represents a of the CIE 1976LAB color space ^* The adjustment factor of the axis is a function of the chroma, ΔL 'is the brightness difference, ΔC' _ab Is color difference, deltaH' _ab For the color difference, the subscript S in formula (8) represents a standard color of a pair of colors for which color differences are to be calculated, b represents a sample color of a pair of colors for which color differences are to be calculated, S _L 、S _H And S is _C The length of the elliptical half-axes is defined as a weight function, allowing individual adjustments to be made from region to region in the CIELAB color space to correct for the uniformity of the space.

In some embodiments, there is a correspondence between different colors HSV and a System On Chip (SOC) bottom register, and a correspondence between a known test and a bottom register setting is pre-stored in the ROM 252, and after obtaining display feature data of the display 275 and an ideal correction target input by a user, the controller 250 performs color correction based on a difference between an HSV actual measurement value of the display feature data of the display 275 and a target value corresponding to the ideal correction target.

In some embodiments, during the color correction of the controller 250 to the display 275, the controller 250 has an overflow protection function, i.e., when the upper limit or the lower limit of the correction curve is reached during the correction, the upper limit or the lower limit is taken as the correction value. It will be understood that, because there are upper and lower limits of HSV adjustment, there are some limits to the material of the display screen, and the adjustment cannot be continued even if the adjustment is to the upper limit or the lower limit, and therefore, when the adjustment reaches the upper limit or the lower limit of the correction curve, the upper limit or the lower limit of the correction curve is taken as the correction value.

In some embodiments, after the controller 250 performs automatic correction based on an algorithm of automatic gamma, automatic white balance, color model (hue saturation value, HSV), 3DLUT, etc., it is determined whether the correction is successful.

In the case of a correction failure, the controller 250 controls the display 275 to issue correction failure information to prompt the user whether to make a correction there. Upon receiving an instruction from the user to confirm the re-correction, the controller 250 performs the auto-correction here based on auto-gamma, auto-white balance, color model (hue saturation value, HSV), 3DLUT, and the like. In the case where an instruction for canceling the re-correction by the user is received, the correction flow ends.

In the case that the correction is successful, the controller 250 controls the display 275 to display the correction effect.

It should be noted that, the algorithm flows adopted in the above embodiments all adopt the existing algorithm, and the embodiments of the present application do not relate to improvements of the existing algorithm.

In some embodiments, controller 250 may control display 275 to split screen display the user interface before correction and the user interface after correction. Exemplary, fig. 12 is a schematic display diagram of a user interface according to an embodiment of the present application. As shown in fig. 12, the controller 250 may divide the display 275 into a first display area for displaying the user interface before correction and a second display area for displaying the user interface after correction. Thus, the display 275 is displayed in a split screen for the user to observe the color and/or brightness changes of the user interface before and after correction, i.e., for the user to observe the color changes of the user interface before and after correction.

It should be noted that the split screen display shown in fig. 12 is merely an example, and the display scale of the split screen display is not limited in the embodiment of the present application.

In some embodiments, controller 250 may control display 275 to display the corrected user interface full screen.

For example, the controller 250 may control the display 275 to display the user interface before correction in a full screen manner after a preset period of time has elapsed, so that the user can observe the color change of the user interface before and after correction. The preset time period may be preset when the display device 20 leaves the factory, for example, the preset time period is 2 seconds.

In some embodiments, after the controller 250 controls the display 275 to display the correction effect, the controller 250 issues a fourth prompt for prompting the user to select the pre-correction setting or the post-correction setting.

Upon receiving an instruction from the user to select a setting before correction, the controller 250 controls the display 275 to display a user interface in accordance with the setting before correction. Upon receiving an instruction from the user to select the corrected setting, the controller 250 controls the display 275 to display the user interface in accordance with the corrected setting.

For example, the controller 250 may control the display 275 to display the fourth prompt, and the content of the fourth prompt displayed by the controller 250 may be "clicking" the confirm "button, then the correction is effective, clicking" cancel "button, then the original setting is restored.

In the case where a click operation of the "confirm" button by the user is received, the controller controls the display 275 to display the user interface in accordance with the corrected setting in response to the click operation. In the case where a click operation for "cancel" button by the user is received, in response to the click operation, the controller 250 controls the display 275 to display the user interface in accordance with the setting before correction.

Further, the correction flow ends.

It can be understood that, since the test device in the embodiment of the application only needs to collect the display feature data of the display and transmit the display feature data of the display to the display device, the display device completes the color correction of the display, that is, in the embodiment of the application, the test device only collects the display feature data and transmits the display feature data, and the specific calculation of the color correction is performed by the display device, so that the calculation force requirement on the test device is lower, that is, the cost of the test device is lower, compared with the existing correction system, the cost of the correction system is reduced by integrating the upper computer software and the signal generator. When the user needs to correct the chromaticity and/or the brightness of the display, the user only needs to place the test equipment at a place where the display characteristic data of the display can be acquired, the display equipment can automatically correct the chromaticity and/or the brightness of the display, the requirement on the operation level of the user is lower, and the cost of a correction system is reduced while the operation difficulty of the user is reduced.
