PROBLEM TO BE SOLVED: To efficiently carry out an anisotropic noise removing process. SOLUTION: In an input device 11, a pickup or scanning of a solid image is carried out, the pickup or scanning is analyzed to acquire a Wiener spectrum, and the Wiener spectrum is stored in a memory 13 as noise information N. When image data S0 is acquired in the input device 11, noise information N corresponding to the input device 11 that has acquired the image data S0 is read from the memory 13, the noise information N is appended to the image data S0 to provide an information-appended image data S1, and the information- appended image data S1 is recorded in a medium or the like in a recording means 15. Consequently, a noise characteristic of the input device 11 can be efficiently acquired by referring to the noise information N appended to the image data S1. COPYRIGHT: (C)2004,JPO |
