摘要

PROBLEM TO BE SOLVED: To reduce a circuit scale while performing the correction of a fixed pattern to a plurality of images having different exposures. ! SOLUTION: An image synthesis device includes: first image acquisition means for acquiring a first image captured in a first exposure time between the first image and a second image captured in a second exposure period including the first exposure period, which is longer than the first exposure period; second image acquisition means for acquiring the second image; detection means for detecting a first pattern from the first image, or for detecting a second pattern from the second image; correction means for correcting the first image on the basis of the first pattern, and for correcting the second image on the basis of the second pattern; synthesis means for synthesizing the first image and the second image corrected by the correction means; and first switching means for switching the connection of the first image acquisition means or the second image acq
