When a digital camera is set to retrieval mode, a map-style retrieval screen having a matrix structure is displayed on a display device. The digital camera searches for images photographed in the regions corresponding to each cell in the matrix structure, based on shooting location information appended to the images. The number of found images is displayed within each cell. When the user inputs a zoom in or zoom out command, the regions corresponding to each cell are made smaller or larger, according to the command. At the same time, a new retrieval is performed for images photographed in the regions corresponding to each of the modified cells. The number displayed within each cell is updated according to the number of images found in the new retrieval. When a single cell is selected, a list view of the images photographed in the region corresponding to the selected cell is displayed.
