IMAGING DEVICE AND IMAGING SYSTEM

摘要

A plurality of exchange lenses designed for object exposure regions of different sizes can be selectively mounted on the present imaging device. The imaging device determines whether a mismatch state is present, in which the size of the object exposure region of an exchange lens mounted is smaller than the size of the imaging region of an imaging element. If it is determined that a mismatch state is present, an image of a partial region of the imaging region is generated and the image of the partial region is displayed as a live view image in a relatively large area (an area larger than an area for displaying the partial region in a live view display when no mismatch state is present). Accordingly, techniques for performing a live view display with favorable visibility are provided.
