IMPRESSION ANALYSIS SYSTEM, IMPRESSION ANALYSIS METHOD, AND PROGRAM

An impression analysis system, includes: an input obtainer that receives an evaluation target image; a feature amount extractor that extracts a low-order image feature amount, and a high-order image feature amount, from the evaluation target image, and a similarity determiner that compares data obtained by extracting a low-order image feature amount and a high-order image feature amount from a reference image associated with an impression evaluation, with data of the image feature amounts extracted by the feature amount extractor, and that calculates a similarity between the evaluation target image and the reference image.
