Abstract
An image input apparatus includes a picture-taking optical system, a facial imaging device, a transparent parallel flat plate member arranged in an optical path of the optical system approximately in parallel with a picture-taking surface of the imaging device, a tilting member to tilt the transparent member with respect to the imaging device so that the image formed on the imaging device is moved, a memory to store each image moved when the transparent member is tilted, and an image synthesizer to synthesize an image of high resolution from the image stored in the memory. Three points not aligned on a straight line are selected from the transparent member, and one point is used as a support point and other two points are used as operation points so that the tilting member is operated through these support and operation points.
