An embryo quality evaluation assistance system including an image pickup unit for picking up an image of the embryo, and a computer that communicates data with the embryo observing apparatus to assist quality evaluation of the embryo. The computer includes a time-series image storing unit that stores a time-series image picked up by the embryo observing apparatus, an embryo image extracting unit that extracts an embryo image from the time-series image, and an active site extracting unit that compares an embryo image based on a first time-series image with an embryo image based on a second time-series image picked up before or after a predetermined time from a pickup time of the first time-series image, and extracts as an active site a set of pixels when the difference between pixel values of corresponding pixels of the first and second time-series images is larger than a predetermined threshold value.
