Abstract: A method and device for detecting uniformity of a dark state image of a display is disclosed. After an acquired dark state image of a display panel is divided into a plurality of areas according to a preset rule, RGB values of each area are determined and converted into XYZ values. The L* and C* values in the CIE-LCH standard are calculated and statistical analysis is performed to the L* and C* values of the areas in the dark state image to determine statistical parameters of the display image. A dark state uniformity coefficient of the dark state image is determined based on the determined statistical parameters, and the uniformity of the dark state image of the display panel is determined through the dark state uniformity coefficient.

Abstract: The present invention discloses a method and device for image detection. After an acquired dark state image of a display panel is divided into a plurality of areas according to a preset rule, RGB values of each area are determined and converted into XYZ values. The L* and C* values in the CIE-LCH standard are calculated and statistical analysis is performed to the L* and C* values of the areas in the dark state image to determine statistical parameters of the display image. A dark state uniformity coefficient of the dark state image is determined based on the determined statistical parameters, and the uniformity of the dark state image of the display panel is determined through the dark state uniformity coefficient. A standard for evaluating uniformity of a dark state image is established through the above process, which facilitates unified detection of uniformity of the dark state image of the display panel.
