摘要： PROBLEM TO BE SOLVED: To obtain a good high resolution image by super resolution processing even when a camera is fixed by a tripod, or the like. SOLUTION: A movement decision unit 45 determines whether a subject in an image is moved on the basis of the extent of displacement between frame images obtained by photographing. A lens control unit 46 drives a zoom lens to intentionally change an optical zoom magnification (and an angle of view for photographing) when the subject is determined to be not moved and the change of a zoom magnification is not indicated by a user. In the process of this change, three frame images mutually different by optical zoom magnifications at photographing are obtained as three low-resolution images. Displacement occurs among the low-resolution images due to the difference of optical zoom magnifications. A high resolution image is generated from three low-resolution images by super resolution processing using the displacement. COPYRIGHT: (C)2011,JPO&INPIT
