<P>PROBLEM TO BE SOLVED: To acquire a regular image and an image (dark-time image) for correction by single imaging, and to rapidly and accurately remove fixed pattern noise such as dark noise in the regular image. <P>SOLUTION: A single imaging element where a group of light reception elements (a first group of light reception elements) for an image on a surface A and a second group of light reception elements corresponding to an image on a surface B are alternately arranged in accordance with a predetermined arrangement form is used. A mechanical shutter is closed after the exposure of the regular imaging, the imaging element is driven according to a predetermined drive sequence, whereby the reading and the sweeping of a charge on the surface B is carried out, and thereafter the reading of the charge on the surfaces A and B and charge transfer are carried out. Thereby, a regular image on the surface A including a noise component and a dark-time image on the surface B comprising only a noise component are acquired. The regular image on the surface A with noise removed therefrom can be obtained by subtracting the dark-time image from the regular image. <P>COPYRIGHT: (C)2010,JPO&INPIT |
