Abstract:
The image input unit comprises a pixel shift evaluation value and reliability calculating section that calculates a pixel shift evaluation value based on image data for a plurality of images photographed before and after an image sensing device is displaced for a predetermined amount. Moreover, a system controller judges whether pixel shift photography has been normally performed or not based on the pixel shift evaluation value, and displays the judgment result on a display.

Abstract:
The present invention aims to provide an imaging apparatus with blur correction function in which a retention lever to mechanically retain an image sensor requires a minimum moving space and the thickness of a lens barrel can be reduced in optical axis direction. The imaging apparatus includes an image sensor (7) photoelectrically converting an image of a subject into an electric signal; an optical photographic system (3) forming the subject image on an imaging plane of the image sensor (7); a lens barrel (4) containing the optical photographic system (3) and being extendable/retractable in an optical axis direction of the optical photographic system (3); a frame member (8, 11) movably supporting the image sensor (7) in a plane perpendicular to the optical axis; a blur correction unit (9) correcting a blur in the image due to hand shake by moving the frame member (8, 11) in a plane perpendicular to the optical axis; and a retainer unit (10) retaining the frame member (8, 11) in one of the optical axis direction and a direction perpendicular to the optical axis.
