Abstract

In the case of reduced display of a shot image, the shot image is displayed in accordance with an attitude of an imaging device at the time of shooting, whereby it is possible to attain an easily viewable and convenient reduced image display regardless of a shooting attitude, and to display a vertically shot image at a reduction ratio which enables sufficient viewability. A display section (55) displays an image in accordance with an image signal. An imaging optical system (L) forms an optical image of an object, and an imaging section (4) receives the optical image formed by the imaging optical system, and converts the optical image. into an electrical image signal. An attitude detection section (43) detects the attitude of the imaging device at the time of the shooting. A recording section (12) records the shot image and attitude information about the attitude of the imaging device. An image display control section (13) restores an orientation of the shot image so as to correspond to the attitude of the imaging device at the time of the shooting, clips a part of reduced image of the restored shot image, and causes the clipped image to be displayed on the display section.
