Embodiment 1

[0028] figure 1 It is a schematic flowchart of a screen color detection method provided in Embodiment 1 of the present application. This embodiment is applicable to the detection of whether there is a color defect in the screen. This method can be executed by a screen color detection device, which can use software and / or implemented in hardware, such as figure 1 As shown, the method specifically includes the following steps:

[0029] S101. Acquire a screen image to be tested, and divide the screen image to be tested into regions according to preset division rules to obtain at least one subregion of the image to be tested.

[0030] The screen image to be tested can be a screen image to be detected for color defects; the screen image to be tested can be obtained by an image acquisition device, for example, the image acquisition device can be a CCD (Charge Coupled Device, Charge Coupled Device) camera or a CMOS (Complementary Metal Oxide Semiconductor, CMOS) camera. It should...

Embodiment 2

[0067] Figure 2A It is a schematic flowchart of a screen color detection method provided in Embodiment 2 of the present application. This embodiment is optimized and improved on the basis of the above-mentioned technical solutions.

[0068] Further, the step "determine the first area of ​​the screen image to be tested based on the RGB average value of at least one sub area of ​​the image to be tested based on the preset first contrast determination algorithm of the image to be tested sub area" is refined into " According to the arrangement order of the image sub-areas to be tested in the screen image to be tested, determine the target sub-area to be tested and the candidate sub-area to be tested from at least one image sub-area to be tested; wherein, the candidate sub-area to be tested is the image sub-area to be tested The image sub-area to be tested except the target image sub-area to be tested in the area; according to the RGB mean value of the target sub-area to be tested...

Embodiment 3

[0100] image 3 It is a schematic diagram of the detection process of a screen color detection method provided in Embodiment 3 of the present application. The embodiment of the present application provides a preferred implementation mode on the basis of the technical solutions of the foregoing embodiments.

[0101] Such as image 3 As shown, where the screen image to be tested should be a uniform color image with an RGB value of 128 when there is no color defect, but there is a color defect on the left side of the current screen image to be tested.

[0102] S1: Acquisition of the image of the screen to be tested: the image of the screen to be tested can be obtained in various ways, for example, it can be taken by a CCD or CMOS camera, or the result of other image preprocessing can be used as the image of the screen to be tested;

[0103] S2: Background image construction: by automatically extracting the normal area, that is, the first area, from the screen image to be tested,...

Abstract

The embodiment of the invention discloses a screen color detection method and device, equipment and a storage medium. The method comprises the following steps: acquiring a to-be-detected screen image, and performing region division on the to-be-detected screen image according to a preset division rule to obtain at least one to-be-detected image sub-region; determining a first region of the to-be-detected screen image based on a preset first contrast determination algorithm of the to-be-detected image sub-region according to the RGB mean value of the at least one to-be-detected image sub-region; determining a background image of the to-be-detected screen image according to the first image information of the first area and the second image information of the to-be-detected screen image; obtaining a contrast image of the to-be-detected screen image based on a preset second contrast determination algorithm according to the pixel point RGB values of the to-be-detected screen image and the background image; and according to a preset threshold segmentation algorithm, determining a second region from the contrast image as a color defect region of the to-be-detected screen so as to complete color detection of the screen.

Description

technical field [0001] The embodiments of the present application relate to the technical field of image processing, and in particular, to a screen color detection method, device, device, and storage medium. Background technique [0002] In recent years, the number of electronic products using OLED (Organic Light-Emitting Diode: Organic Light-Emitting Semiconductor) screens has increased day by day. For example, OLED screens can be used in various electronic products such as smartphones, tablet computers, and LCD TVs. Compared with other types of screens, OLED screens have the characteristics of low power consumption, high color gamut, and thinner and lighter. [0003] In the process of detecting color defects on the screen, the normal area of ​​the screen is usually determined artificially, and the difference in color temperature between the normal area of ​​the screen and other areas is compared, so as to detect whether there is a color defect on the screen. However, ther...
