CHANGE IMAGE DETECTION DEVICE, CHANGE IMAGE DETECTION METHOD AND COMPUTER PROGRAM FOR ACHIEVING THOSE FUNCTIONS, AND RECORDING MEDIUM WITH THE COMPUTER PROGRAM RECORDED THEREON

摘要

PROBLEM TO BE SOLVED: To provide a technology for detecting a change image in a relatively short time from among a plurality of time-series images.;SOLUTION: This change image detection device is provided with: a change image detection part; and a decision part for comparing the Na-th partial region among N partial regions in an image to be processed with a region at a position corresponding to the Na-th partial region in a reference image to decide its change. When the decision part decides that there is no change, the change image detection part selects an image later than the target image as a new target image, and the decision part decides the change in the Nb-th partial region in the new target image and the corresponding region for the Nb-th partial region, and when the decision part decides that there is any change, the change image detection part selects the target image or an image later than the target image as a reference image, and detects the target image or the image later than the target image as a change image.;COPYRIGHT: (C)2008,JPO&INPIT
