IMPRESSION ANALYSIS SYSTEM, IMPRESSION ANALYSIS METHOD, AND RECORDING MEDIUM

An impression analysis system includes: an input obtainer that receives an evaluation target image; and a hardware processor, wherein the hardware processor: extracts a low-order image feature amount, and a high-order image feature amount, from the evaluation target image, and 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 a feature amount extractor, and calculates a similarity between the evaluation target image and the reference image.
