摘要： PROBLEM TO BE SOLVED: To provide an image evaluation device which is capable of evaluating visual influences caused by moire by improving accuracy in comparison with the case where the present configuration is not included.SOLUTION: A moire frequency detection section 1 detects a frequency in the case where moire occurs, from an angle and a frequency of a screen to be used for forming an image subjected to evaluation. A frequency conversion section 2 performs frequency conversion on luminosity of the image subjected to evaluation and acquires one-dimensional frequency distribution and in accordance with visual characteristics, a visual characteristic correction section 3 corrects a differential between the one-dimensional frequency distribution and frequency distribution of an image of a primary color corresponding to average luminosity of the image subjected to evaluation. An evaluation section 4 calculates an evaluation value by extracting a moire component of the frequency detected by the moire frequency detection section 1 from the corrected frequency distribution. Further, an evaluation value of a screen component is calculated, and an evaluation value relating to a structural sense may also be calculated together with the evaluation value of the moire component.
