摘要

A movement quantity calculation unit 102 calculates an image movement quantity between a new frame and a previous frame, each including image data in frame units comprising a dynamic image photographed one after another by a camera 1, based on difference in image data between the frames. A storage control unit 104 stores in a time-lapse photographed image storage area 107 either the image data of the new frame or that of the previous frame as a time-lapse photographed image in the case where the image movement quantity calculated by the movement quantity calculation unit 102 has changed from being equal to or greater than a predetermined value to being less than the predetermined value.

主权项

1. A photographed image storage control apparatus comprising:
an input means for continuously receiving a plurality of image frames in response to an input by a user which initiates a time lapse photography mode, each image frame including image data in frame units comprising a dynamic image photographed by a photographing means at a predetermined interval; a movement quantity calculation means for calculating an image movement quantity between a new frame and a previous frame among the plurality of received image frames based on a difference in image data between the new frame and the previous frame; and a storage control means for storing in a storage means either the image data of the new frame or image data of the previous frame as a first time-lapse photographed image in a time lapse set of images when the image movement quantity calculated by the movement quantity calculation means has changed from being equal to or greater than a predetermined value to being less than the predetermined value, wherein: the storage control means does not store in the storage means the image data as the first time-lapse photographed image if the image movement quantity remains less than the predetermined value, while operating in the time lapse photography mode and without requiring any further input by the user, the movement quantity calculation means calculates a subsequent image movement quantity between each pair of image frames received subsequent to the new frame by the input means, and the storage control means stores in the storage means image data of one image frame among the pair of image frames as a next time lapse photographed image in the time lapse series of images, whenever the subsequent image movement quantity calculated by the movement quantity calculation means changes from being equal to or greater than the predetermined value to being less than the predetermined value.
