In S702 the control unit 11 determines whether a selection for image data was inputted while the thumbnails for image data are displayed in the display area 101. That is, the control unit 11 determines whether or not an electric signal corresponding to the region of the touch panel 103 in which a thumbnail is displayed was inputted from the touch panel 103. When an electric signal corresponding to such a region has been inputted, the control unit 11 determines that a selection was inputted for image data corresponding to the thumbnail displayed in the region corresponding to the electric signal. The control unit 11 continues to loop back to S702 and repeat the determination while determining that an image data selection has not been inputted (S702: NO). Once the control unit 11 determines that an image data selection was inputted (S702: YES), the control unit 11 advances to S703.
