KEY FRAME EXTRACTOR, KEY FRAME EXTRACTION PROGRAM, KEY FRAME EXTRACTION METHOD, IMAGING APPARATUS, AND SERVER DEVICE

摘要

PROBLEM TO BE SOLVED: To extract a key frame from moving image data accurately at a low cost.

SOLUTION: A key frame extractor includes: a scene analysis part 510 for analyzing the moving image data and detecting scenes; a key frame extraction part 520 for extracting a frame image time-sequentially at the center or near the center as a key frame from the plurality of frame images corresponding to the scene having the longest scene length among the plurality of scenes detected by the scene analysis part 510; a feature amount analysis part 530 for normalizing the key frame, extracting the feature amount of an image, executing clustering processing, and generating a feature amount histogram; and a classification processing part 540 for performing machine learning and classification based on the feature amount histogram.
