When a predetermined image switching operation is started, a control section refers to a judgment result as to whether a display portion specified in advance by a touch operation has been identified as a search target. If no display portion has been identified, the control section performs display control in response to the predetermined image switching operation such that images sequentially selected in a forward or reverse direction from a stored image group of images arranged according to a predetermined criterion are displayed on a display section. If a display portion has been identified as a search target, the control section performs display control such that a relevant search condition is acquired with reference to a search condition table based on the search target, the stored image group is searched for another image other than an image being displayed based on the search condition, and the found image is displayed.
