Before explaining the technical solutions provided by the embodiments of the present application, in order to facilitate understanding of the embodiments of the present application, the present application first specifically explains the problems existing in the related art:
the inventor researches and discovers that the design scheme of the UDC module can be as follows: the drive circuit in UDC region (the region that sets up leading camera) adopts transparent metal to walk the line, and emitting pixel adopts the reduction number or reduces the area, has guaranteed the luminousness in UDC region through these modes in order to guarantee the photographic effect of leading camera. Due to the fact that the design of the UDC area is different from that of a normal display area, the luminous intensity of the pixels and the luminous intensity of the pixels are not consistent with the time-lapse decay curve. For example, as shown in fig. 1, a curve 1 represents a curve in which the luminance of two areas before the UDC module leaves the factory coincides, a curve 2 represents a luminance curve of a normal display area after the UDC module is used for a long time, and a curve 3 represents a luminance curve of a UDC display area after the UDC module is used for a long time, for example, the luminance of the UDC display area is more rapidly decreased, which causes a significant luminance difference between the UDC display area and the normal display area after the UDC display module is used for a long time, thereby greatly reducing the experience of a user.
For the inconsistency of brightness attenuation of the UDC display area and the normal display area, in the related art, the aging compensation data is usually established before the UDC module leaves the factory and stored in the memories of the mass-produced UDC modules, however, when the characteristic fluctuation of the mass-production modules is large, the compensation effect is poor, and the capacity of the memories is required to be increased to store the aging compensation data, which results in the increase of the module cost.
Embodiments of a gamma debugging method, a gamma debugging system, an electronic device, and a computer-readable storage medium are described below with reference to the accompanying drawings.
For better understanding of the present application, the gamma debugging system provided by the embodiments of the present application will be described first.
As shown in fig. 2, the gamma debugging system provided by the embodiment of the present application may include a first electronic device 100 and a second electronic device 200. The first electronic device 100 includes a first display region a1 and a second display region a2, and the first display region a1 has a light transmittance greater than that of the second display region a 2. The first electronic device 100 may be understood as including a UDC module, the first display area a1 may be correspondingly disposed with an off-screen camera, i.e., a UDC display area, and the second display area a2 is a normal display area. The second electronic device 200 comprises an image acquisition module 202. The first electronic device 100 and the second electronic device 200 can cooperate with each other, so as to implement gamma debugging on the first electronic device 100.
For example, as shown in fig. 3, in the gamma debugging system provided in the embodiment of the present application, the first electronic device may perform steps S110 to S120, and the second electronic device 200 may perform steps S210 to S240.
S210, sending a display instruction to the first electronic equipment;
s110, enabling the first display area and the second display area to display a to-be-detected gray scale picture;
s220, the image acquisition module acquires display images of the first display area and the second display area;
s230, judging whether the first optical parameters corresponding to the gray scale pictures to be detected displayed in the first display area and the second display area meet the preset requirements or not according to the collected images;
s240, if not, sending a gamma register adjusting instruction to the first electronic equipment;
s120, adjusting a current gamma register value corresponding to the gray scale picture to be detected, wherein under the adjusted current gamma register value, the first display area and the second display area display a second optical parameter corresponding to the gray scale picture to be detected to be superior to the first optical parameter.
According to the gamma debugging system provided by the embodiment of the application, the inventor breaks through the conventional thinking in the related technology, on one hand, the first electronic equipment can carry out gamma debugging on the first electronic equipment at any time after leaving the factory, namely, the gamma debugging can be carried out at any time in the whole life cycle of the first electronic equipment to realize aging compensation, and further the problem of inconsistent display effect caused by inconsistent attenuation of the first display area and the second display area is reduced or eliminated; on the other hand, compared with the prior art that aging compensation data is established before delivery and stored in memories of all mass-produced UDC modules, the mass-produced UDC modules have characteristic differences, and the aging compensation effect achieved through a prediction mode is not necessarily ideal, in the application, gamma debugging can be carried out at any time in the whole life cycle of the first electronic equipment to achieve aging compensation, personalized debugging of the single first electronic equipment can be achieved, and a better effect can be achieved according to real-time display effect debugging than through the prediction mode; in another aspect, in the gamma debugging process, the display effects of the first display area and the second display area of the first electronic device can be acquired by combining the second electronic device with the image acquisition module, so that a consumer can start the gamma debugging of the first electronic device at any time, and can utilize the existing resources at the side, such as a mobile phone, a tablet computer, a wearable product and the like as the second electronic device.
For example, the second electronic device may send a display instruction according to the gray scale display range of the first electronic device. For example, the first electronic device has 256 levels of gray scales of 0-255, and the second electronic device can select the image corresponding to part of the gray scales of 0-255 to transmit the display command, or select the image corresponding to all the gray scales of 0-255 to transmit the display command.
The gray scale picture to be detected can be a white picture or a monochrome picture corresponding to a certain gray scale. If the gray scale picture to be detected is a white picture, the gamma register values corresponding to the sub-pixels of the colors of the first electronic equipment under the gray scale picture to be detected can be adjusted at the same time. If the gray scale picture to be detected is a monochrome picture, the gamma register value corresponding to the sub-pixel with the corresponding color of the first electronic equipment can be adjusted. Different gray scales correspond to different gamma register values, and the gamma register value corresponding to the gray scale to be detected under the picture can be understood as the register value corresponding to the gray scale to be detected.
For example, the first electronic device includes a red sub-pixel, a green sub-pixel and a blue sub-pixel, and the gamma register values of the red sub-pixel, the green sub-pixel and the blue sub-pixel at the 255 gray level can be adjusted at the same time when the to-be-detected gray level image is a 255 gray level white image. Similarly, if the gray scale image to be measured is a 255 gray scale red image, the gamma register value of the red sub-pixel under the 255 gray scale can be adjusted.
For example, in the embodiment of the present application, each of the first electronic device and the second electronic device may be any one of a mobile phone, a tablet computer, and a wearable product. For example, the second electronic device may also include two display areas, where a light transmittance of one display area is greater than that of the other display area, and the display area with the greater light transmittance is correspondingly provided with the off-screen camera.
For example, the image capturing module of the second electronic device may specifically include a first camera and a second camera, where a resolution of the first camera is greater than a resolution of the second camera, and S220 may specifically include capturing, by the first camera, display images of the first display area and the second display area. The higher the resolution of the camera, the clearer the acquired image, and thus the more accurate the analysis of the optical parameters based on the acquired image.
Illustratively, as shown in fig. 2, the image capturing module 202 of the second electronic device is a rear camera, and when capturing the display images of the first display area and the second display area, the image capturing module 202 of the second electronic device may be directed to the display surface of the first electronic device. The display images of the first display area and the second display area can be collected simultaneously, and the display images of the first display area and the second display area can also be collected respectively.
The first optical parameter may be understood as a display parameter before the first electronic device is adjusted, and the second optical parameter may be understood as a display parameter after the first electronic device is adjusted. According to the embodiment of the application, the second optical parameter after adjustment is better than the first optical parameter before adjustment, and the second optical parameter can meet the preset requirement or not.
For example, the first optical parameter and the second optical parameter may include a luminance difference and/or a color coordinate difference between a first display area and a second display area of the first electronic device, and the preset requirement may include that the luminance difference between the first display area and the second display area of the first electronic device is within a first preset range and/or that the color coordinate difference between the first display area and the second display area is within a second preset range. It is understood that the smaller the first preset range and the second preset range, the higher the debugging accuracy. In order to pursue the highest debugging accuracy, the first preset range and the second preset range may include 0, so that the first display area and the second display area of the first electronic device may be free from a brightness difference and a color coordinate difference as much as possible after the gamma debugging.
For example, the second optical parameter is better than the first optical parameter, which means that the brightness difference between the first display area and the second display area after adjustment is smaller than the brightness difference between the first display area and the second display area before adjustment, and/or the color coordinate difference between the first display area and the second display area after adjustment is smaller than the color coordinate difference between the first display area and the second display area before adjustment.
For example, in S240, the adjusting instruction sent by the second electronic device may include an instruction to increase or decrease the gamma register value. For example, the second electronic device may determine to increase or decrease the gamma register value according to a difference between the first optical parameter corresponding to the to-be-tested gray scale image displayed in the first display area and the second display area and a preset requirement, and directly send an adjustment instruction including an adjustment direction, so that the gamma debugging efficiency can be improved. In addition, in this application embodiment, the second electronic device directly sends the instruction after acquiring the image and analyzing the display effect, and compared with the case where the second electronic device sends the acquired image to the first electronic device, the first electronic device directly sends the instruction by the second electronic device to improve the transmission efficiency and further improve the gamma debugging efficiency when analyzing the display effect.
Optionally, the adjusted corresponding second optical parameter may meet a preset requirement. For example, S120 may specifically include: and adjusting the current gamma register value corresponding to the gray scale picture to be detected until the first display area and the second display area display the second optical parameters corresponding to the gray scale picture to be detected under the adjusted current gamma register value and meet the preset requirement.
For example, S120 executed by the first electronic device may specifically include: and adjusting the current gamma register value corresponding to the gray scale picture to be detected, and then enabling the first display area and the second display area to display the gray scale picture to be detected based on the adjusted current gamma register value. And then the second electronic equipment acquires the display images of the first display area and the second display area again, judges whether the second optical parameters meet the preset requirements again according to the acquired images, if not, the second electronic equipment sends an adjusting instruction to the first electronic equipment again, then the first electronic equipment adjusts the current gamma register value corresponding to the gray scale picture to be detected again until the second optical parameters corresponding to the gray scale picture to be detected displayed by the first display area and the second display area meet the preset requirements under the adjusted current gamma register value. That is to say, under the condition that the optical parameter based on the current gamma register value cannot meet the preset requirement, the second electronic device may send a multiple-adjustment instruction, and the first electronic device may perform multiple adjustments until the second optical parameter based on the adjusted current gamma register value meets the preset requirement.
For example, gamma debugging can be performed under multiple gray-scale pictures to be tested in the above manner.
In some optional embodiments, after S230, if yes, the second electronic device may further sequentially send an instruction to the first electronic device to enable the first display area and the second display area to sequentially display the other gray scale frames to be detected. The first electronic equipment can enable the first display area and the second display area to sequentially display other multiple gray scale pictures to be detected. The second electronic equipment can sequentially acquire and judge whether the first optical parameters corresponding to the other to-be-detected gray scale pictures displayed in the first display area and the second display area meet the preset requirements or not; if the first display area and the second display area display that the first optical parameters corresponding to other gray scale pictures to be detected do not meet the preset requirements, the second electronic equipment sequentially sends instructions for adjusting the current gamma register values corresponding to other gray scale pictures to be detected to the first electronic equipment, the first electronic equipment can sequentially adjust the current gamma register values corresponding to other gray scale pictures to be detected, and under the adjusted current gamma register values, the first display area and the second display area display that the second optical parameters corresponding to other gray scale pictures to be detected are superior to the first optical parameters corresponding to other gray scale pictures to be detected.
According to the embodiment of the application, gamma debugging under a plurality of gray scale images to be detected can be automatically completed, so that the first electronic equipment has a better display effect when displaying different gray scale images, for example, the brightness and the color of the first display area and the second display area of the first electronic equipment are consistent when displaying different gray scale images.
Similarly, for other gray scale images to be measured, the second optical parameter after adjustment is superior to the first optical parameter before adjustment, and the second optical parameter may or may not meet the preset requirement.
For example, for each of the other frames with gray scales to be measured, the adjusted corresponding second optical parameter may reach the preset requirement. For example, the second electronic device sequentially sends an instruction for adjusting the current gamma register values corresponding to other gray scale pictures to be detected to the first electronic device, the first electronic device may sequentially adjust the current gamma register values corresponding to other gray scale pictures to be detected, and under the adjusted current gamma register values, the first display area and the second display area display second optical parameters corresponding to other gray scale pictures to be detected that are better than the first optical parameters corresponding to other gray scale pictures to be detected, which may specifically include: and the second electronic equipment sequentially sends instructions for adjusting the current gamma register values corresponding to the other gray scale pictures to be detected to the first electronic equipment, and the first electronic equipment can sequentially adjust the current gamma register values corresponding to the other gray scale pictures to be detected until the first display area and the second display area display second optical parameters corresponding to the other gray scale pictures to be detected and meet the preset requirement under the adjusted current gamma register values. For example, the total number of the frames to be tested may be set according to the gray scale range of the first electronic device, and each frame to be tested may correspond to one gray scale value. For example, some gray level binding points can be selected, and the gray level picture to be detected is set and stored in the memory of the second electronic device.
Optionally, the number of gray scales of the plurality of frames to be tested may be the same as the number of gray scales of the first electronic device. For example, the displayable gray scale range of the first electronic device is 0 to 255, and the total number of the gray scale pictures to be detected can be 256.
Taking selecting some gray level bindings, setting a to-be-detected gray level picture, and the to-be-detected gray level picture is a white picture as an example, the second electronic device may sequentially send display instructions for displaying a W255 picture (a 255 gray level white picture), a W224 picture, an … … W1 picture, and the like to the first electronic device.
In order to better understand how the first electronic device and the second electronic device complete the gamma debugging under the multiple gray-scale images to be tested in sequence, referring to fig. 4, the steps performed by the first electronic device and the second electronic device may include S410 to S460.
For example, in S410, the second electronic device may send a display instruction to the first electronic device, where the display instruction includes an instruction for causing the first display area and the second display area to display the to-be-tested grayscale picture. The second electronic equipment can control the first electronic equipment to send and display one of the plurality of frames of the gray scale to be detected each time. And the first electronic equipment displays the to-be-detected gray scale picture after receiving the display instruction.
And S420, the second electronic equipment photographs the to-be-detected gray scale picture displayed by the first electronic equipment.
S430, the second electronic device judges whether the optical parameters corresponding to the gray scale picture to be detected displayed in the first display area and the second display area meet the preset requirements.
If the determination result in the S430 is "no", then S440 is executed, the second electronic device sends a gamma register adjustment instruction to the first electronic device, the first electronic device adjusts a current gamma register value corresponding to the to-be-detected gray-scale picture after receiving the adjustment instruction, and displays the to-be-detected gray-scale picture based on the adjusted current gamma register value.
S420 to S430 are then executed.
If the determination result in S430 is "yes", S450 is executed, and the second electronic device determines whether the display instruction of all the frames of the to-be-detected gray scales is sent to the first electronic device.
If the determination result in S450 is "no", then S410 is executed, and the second electronic device may send a display instruction for displaying the next to-be-tested gray-scale image to the first electronic device.
If the determination result in S450 is "yes", then S460 is executed, in which the first electronic device reads and stores the adjusted current gamma register value corresponding to each to-be-detected gray-scale picture. The gray scale picture to be detected corresponds to the gray scale, so that the gamma register value finally corresponding to each gray scale can be stored. Of course, each time the debugging of one gray scale image to be tested is completed, the first electronic device may also read and store the adjusted current gamma register value corresponding to the gray scale image to be tested.
