DETECTING CROSSTALK ON A DISPLAY SURFACE COMPARTMENTALIZED INTO DISPLAY REGIONS BY IMAGE PATTERNS CONTAINED IN AN INPUT IMAGE SIGNAL TO A DISPLAY DEVICE

摘要

The instant application describes a method for detecting crosstalk on a display surface compartmentalized into display regions by image patterns that are contained in an input image signal to a display device. The method includes steps of: displaying a first image and a second image on a display surface, the first image including first pattern images having main regions depicted with different brightness from each other and the second image including second pattern images having the main regions and sub regions depicted with different brightness from the main regions; taking an image of the display surface to obtain image data; and comparing at least one of the first and second images with the image data to detect the crosstalk. The first and second pattern images are displayed in a center region at a center of the display surface and adjacent regions adjacent to the center region.
