Imaging apparatus, user interface, and associated methodology for a co-existent shooting and reproduction mode

A currently captured image R of an object is displayed nearly at a center portion of a display frame SC on a display screen ST that is a shooting mode. When a time dial is rotated for one step in the counterclockwise direction, the currently captured image R is moved rightward. A reproduced image P captured before the currently captured image R is displayed on the left thereof. A reproduced image P captured before the reproduced image P is displayed on the left thereof. The currently captured image R and the reproduced images P and P are displayed at the same time on a display screen ST as a co-existent state of a shooting mode and a reproducing mode. When the time dial is rotated for one step in the counterclockwise direction, only the reproduced images P to P are displayed on a display screen ST that is a reproducing mode. As a plurality of reproduced images, the reproduced images P to P are displayed along a time axis.
