Abstract

The embodiment of the present invention discloses a color shift detection method, which includes: detecting the current position of the display screen to be detected; if the current position of the display screen to be detected is a preset photographing position, controlling the displaying a preset image on the display screen to be detected; controlling a preset black and white camera to photograph the display area where the display screen to be detected displays a preset image to obtain a grayscale image corresponding to the display screen to be detected; The grayscale value of the high-resolution image is analyzed to obtain a target analysis result; if the target analysis result satisfies a preset threshold condition, it is determined that the color cast of the display screen to be detected is qualified. The embodiment of the present invention also provides an electronic device and a computer-readable storage medium.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a color shift detection method, electronic equipment and a computer-readable storage medium. Background technique [0002] With the rapid development of science and technology, display screens have also been widely used. In existing display screen applications, as liquid crystal display (Liquid Crystal Display, LCD) technology becomes more and more mature, LCDs are more and more widely used. The LCD can be used as any display screen for displaying information, such as a computer display screen, a TV display screen, a smart mobile terminal display screen, and the like. However, LCDs are produced in large quantities in industrial production at the same time, and LCD color shift defects are prone to occur, that is, when LCDs display images during application, the color of the displayed images will deviate, for example, when displaying a pure green image, causing users Wh...
