Abstract:
1. An image acquisition apparatus comprising: an imaging optical system; an imaging section which has a plurality of imaging pixels disposed at non-uniform intervals within an imaging surface, and picks up an object image imaged by the imaging optical system to convert the object image into image signals; and an image restoration processing section which has a coefficient memory in which a predetermined coefficient sequence is recorded, and an image restoration processing circuit which carries out computation processing between the coefficient sequence recorded in the coefficient memory and the image signals from the imaging section, said image restoration processing section generating an image in a desired display pixel arrangement, wherein an interval between adjacent pixels of the plurality of imaging pixels is set based on the fact that a spatial transfer characteristic of the imaging optical system differs in accordance with a position within the imaging surface, and wherein an arrangement of the plurality of imaging pixels is such that the interval between adjacent pixels is set such that integral values, in a region in which sensitivity distribution functions corresponding to adjacent imaging pixels overlap one another, are substantially uniform within the imaging surface.
