<P>PROBLEM TO BE SOLVED: To provide a color-unevenness inspection device and a color-unevenness inspection method, capable of performing more appropriate color-unevenness inspection than ever before. <P>SOLUTION: An image processing part 21 specifies a color-unevenness region, classifies display pixels in the color-unevenness region into a plurality of color groups, and generates a color-unevenness image, in a pickup image (pickup data Din) to be inspected of a display screen of a display device 4. The image processing part 21 also calculates an evaluation parameter (surface ratio S and the maximum chroma Cmax) during color-unevenness inspection, regarding to the color-unevenness region of the color-unevenness image. A correction part 22 making a correction to the calculated evaluation parameter in consideration of a difference of color-unevenness visibility between the color groups. An inspection part 23 performs a color-unevenness inspection based on a resultant evaluation parameter (color-unevenness area ratio S' and the maximum chroma Cmax'). An objective color-unevenness inspection more matching feelings of human being than ever before is realized. <P>COPYRIGHT: (C)2011,JPO&INPIT |
