Abstract:
Provided is an image synchronization device that can stably synchronize a multi-viewpoint image. The present invention comprises: a norm calculation unit that calculates a norm from time series data pertaining to the coordinates of joints of a human body in images photographed from a plurality of viewpoints, the norm being the amount of movement of each joint in each image per unit time; a motion rhythm detection unit that detects, on the basis of the norm, a motion rhythm comprising a movement start time and a movement stop time for each joint in each image; and a time shift detection unit that calculates a matching score indicating the degree of stability of a time shift between the images on the basis of the motion rhythm of each joint in each image, and detects a time shift having a high matching score.
