A plurality of captured images having a successive relation is displayed on a display screen with the successive relation being maintained. Then, when the plurality of captured images include a plurality of first captured images acquired by a plurality of successive photographing operations and a second captured image acquired by an individual photographing operation different from the plurality of successive photographing operations, the second captured image is displayed such that it is differentiated from the plurality of first captured images by, for example, the background area of the second captured image being represented in a display form different from that of another area.
