摘要

PROBLEM TO BE SOLVED: To provide an image quality evaluation device by which evaluation values can be easily obtained with high accuracy from one test chart. SOLUTION: Since the image quality evaluation device provides two image quality evaluation values or more with respect to at least one of the gradation and the color characteristics obtained on the basis of an electric signal obtained resulting from a picked up image of the test chart G placed on a stage 5, it is not required to prepared different test charts from evaluations as by a conventional technology. Therefore the image quality evaluation device performs evaluation more easily with high accuracy, without using a wrong test chart.
