  • Method and system for evaluating performance of image display device
    Patent number: 10458847
    Abstract: A luminance evaluation image 1 has a determination portion 3 configured such that luminance changes progressively between low and high luminance regions 3a and 3b defined to have luminance levels lower and higher than an upper limit of luminance displayable on the image display device 4, respectively. A chromaticity evaluation image has a determination portion configured such that chroma changes progressively between low and high chroma regions defined to have chroma levels lower and higher than an upper limit of chroma displayable on the image display device 4, respectively. At least either the luminance evaluation image or chromaticity evaluation image is displayed on the image display device 4 to evaluate characteristics of the image display device 4 from a position of a boundary B1 in the determination portion 3.
