Abstract:
1. An imaging apparatus adapted to implement electrical image restoration processing, characterized by comprising: a zoom lens comprising a plurality of lens groups and adapted to implement zooming from a wide-angle end to a telephoto end with a change in a space between said plurality of lens groups, an imaging device having an imaging plane located at a position where an image formed by said zoom lens is received at, and adapted to take said image, and an image restoration processor adapted to implement signal processing by which image restoration is implemented on the basis of a signal for the image taken by said imaging device to generate an image signal for a restored image, wherein: the signal processing for implementing said image restoration at said image restoration processor involves processing for electrically implementing image restoration using a restoration filter on the basis of a point spread function regarding an imaging capability of said zoom lens, and said zoom lens and said imaging device have a relation that satisfies the following condition (1): where: L is an axial maximum length from the refracting surface of the zoom lens nearest to the object side to the imaging plane, f f Fno is a minimum F-number at the telephoto end, and Ih is one-half the diagonal length of an effective imaging area on the imaging plane, provided that the effective imaging area is a maximum area used for image display in an area on said imaging plane with said image formed on it, and when said zoom lens has a focusing function, each value is found upon focusing on an axially farthest object.
