摘要：PROBLEM TO BE SOLVED: To more appropriately manage an image file regarding a method for managing the image file to be created according to a prescribed format. SOLUTION: When the image file is transferred from a camera to a server, presence/absence of an image file duplicated in both is determined in advance. In order to determine coincidence of the image file, image files with coincident file size are first specified (S12-S16). When the files with the coincident size exist, then, partial hash values by summarizing head parts of the image files are calculated and compared with each other (S18-S24). When the partial hash values coincide with each other, all the hash values by summarizing the whole image file are further calculated and compared with one another (S28-S30). The image files in which all of the file size, the partial hash values and all the hash values coincide with each other are determined as identical files (S34). The image files in which any one does not coincide are determined as separate files and transmission of the image files is requested to the camera (S32). COPYRIGHT: (C)2007,JPO&INPIT
