<P>PROBLEM TO BE SOLVED: To provide an optical device having plural photographing optical systems with optical axes different from one another capable of generating an image with high picture quality. <P>SOLUTION: An image is obtained by subjecting photo-electric conversion to an optical image formed by a photographing optical system of an optical device having anti-reflection coatings 16 and 17 formed on optical surfaces 9 and 11 at corresponding positions on optical axes O1 and O2 of photographing optical systems 6 and 7. The obtained image is subjected to image processing including specific processing in which ghost images 14 and 15 generated in the image due to reflection on the optical surface are specified, and removal processing in which the ghost images specified by the specific processing are removed from each image. The anti-reflection coatings have reflection characteristics different from each other so that it is possible in the specific processing to specify the ghost images on the basis of the optical characteristic difference in the ghost images. <P>COPYRIGHT: (C)2013,JPO&INPIT |
