Patent ID: 8094207

Claim:
An imaging system comprising: an imaging lens; an imaging device that has a light receiving surface on which a plurality of light receiving pixels are two-dimensionally arrayed and that forms first image data based on an optical image of a subject projected onto the light receiving surface through the imaging lens and outputs the first image data corresponding to the subject; a coefficient storage section that will store a restoration coefficient corresponding to a state of a point image, which is projected onto the light receiving surface through the imaging lens and is expressed by the first image data output from the imaging device, when a maximum diameter of an effective region of the point image is a size covering three or more pixels; and a signal processing section that executes restoration processing on the first image data by utilizing the restoration coefficient, the restoration processing being executed to generate second image data equivalent to the first image data output from the imaging device when a resolving power of the imaging lens is higher, wherein the signal processing section executes the restoration processing in a condition where a pixel region covering total nine or more pixels including three or more pixels in a vertical direction and three or more pixels in a horizontal direction on the light receiving surface is set as a minimum unit, wherein the coefficient storage section will store a correction-completed restoration coefficient obtained by further correction of the restoration coefficient according to a state of the point image expressed by the first image data, the restoration coefficient being selected corresponding to the state of the point image among candidates of a plurality of types of restoration coefficients corresponding to respective states of point images classified into a plurality of types.
