The pixel value, which is the value assigned by the computer when the image is digitized, represents the average luminance and/or color information of a certain small square or point of the image. Specific pixel values may be represented by standard primary colors.
One possible implementation is to represent the pixel values by taking the RGB values, i.e. the standard red, green and blue luminance values of the displayed image. Specifically, acquiring the standard RGB values includes: acquiring red brightness values, green brightness values and blue brightness values (hereinafter referred to as RGB values) of a plurality of pixels in a display image; counting the RGB value of each pixel to obtain the RGB value with the maximum occurrence probability; and determining the RGB value with the maximum occurrence probability as the standard RGB value of the display image.

And acquiring a difference value between the maximum value and the minimum value in the standard RGB values, and judging whether the difference value is greater than a first preset threshold value. And if the difference is smaller than a first preset threshold, judging that the terminal screen does not have color cast, and if the difference is larger than the first preset threshold, judging that the terminal screen has color cast.
Examples of the invention
810 divides the first range image and the second range image into set sub-regions.
And dividing the first range image and the second range image into a plurality of sub-areas according to a set rule, such as a criss-cross mode, a staggered division mode and the like.
820 comparing pixel values of pixel points among the sub-regions, and determining the sub-region with larger difference as an abnormal region of the display screen of the terminal to be detected.
And counting the pixel values of the pixel points in each sub-area, wherein the pixel value is a value given by a computer when the image is digitalized and represents the average brightness information of a certain small square or point of the image. Specific pixel values may be represented by standard primary colors. One possible implementation is to represent the pixel values by taking the RGB values, i.e. the standard red, green and blue luminance values of the displayed image.
By counting the pixel value with the highest probability of occurrence in each sub-region or the average pixel value of the sub-region, etc. The pixel values with the highest probability of occurrence for each sub-region or the average pixel value are then compared to determine the correspondence between the sub-regions. If the difference of pixel values between the sub-regions exceeds a set threshold, it can be judged that color cast occurs.

and sending an instruction for moving the floating icon to the terminal to be detected so as to control the terminal to be detected to move the floating icon out of the range of the original position.
5. The method of claim 1, wherein the identifying the images in the first range and the second range, and the determining the defect information of the terminal screen to be detected comprises:
extracting the pixel value with the maximum probability from the pixel values in the first range and the second range, and determining the pixel value with the maximum probability as a standard value;
and acquiring pixel points with the difference from the standard value exceeding a set threshold value in the pixel values in the first range and the second range, and determining the pixel points as the defect information of the display screen of the terminal to be detected.
6. The method of claim 1, wherein the identifying the images in the first range and the second range, and the determining the defect information of the terminal screen to be detected comprises:
dividing the first range image and the second range image into set sub-regions;
and comparing pixel values of pixel points among the sub-regions, and determining the sub-region with larger difference as an abnormal region of the display screen of the terminal to be detected.
7. A detection method for a terminal screen is characterized by comprising the following steps:
shooting a first image of a display screen of a terminal to be detected, wherein a pure-color image and a floating icon are displayed on the display screen of the terminal to be detected;
moving the floating icon to be out of the original position range of the floating icon, and shooting a second image of the display screen of the terminal to be detected;
sending the first image and the second image to a server, enabling the server to identify the first image and the second image, and determining defect information of a display screen of the terminal to be detected according to an identification result; the method specifically comprises the following steps: extracting an image in a first range from a display screen range of a terminal to be detected in the first image, and extracting an image in a second range from the display screen range of the terminal to be detected in the second image, wherein the combination of the first range and the second range is not less than the range of the display screen of the terminal to be detected, and the first range and the second range do not contain the suspension icon;
and identifying the images in the first range and the second range, and determining the defect information of the terminal screen to be detected.
8. A detection device, comprising:
a processor, a memory for storing the processor-executable instructions;
wherein the processor is configured to call instructions stored in the memory to cause the detection apparatus to perform any of the methods of claims 1-7.
9. A computer-readable storage medium having stored therein instructions that, when executed on a detection apparatus, cause the detection apparatus to perform any of the methods of claims 1-7.
