ABSTRACT:
In the case where a digital camera is used for evaluating a display quality of an image display panel, moire is generated due to a shift of a pixel pitch between a pixel of a panel and a pixel of a digital camera, and thus, a great influence is given as measurement deviation. The present invention carries out a panel display quality evaluation at low cost and short time with relieved influence of moire by treating a value, which is obtained by recognizing a coordinate of a panel pixel in a shot image based on an image for detecting a coordinate and positional information thereof with high accuracy and by calculating average luminance by panel pixel unit based on a center position of a coordinate, as representative luminance in each pixel of the panel, in a panel evaluation method of shooting an image display panel with a digital camera.
