To shorten a time until a display state of an image becomes a desired state.

A display control unit 203 controls a display unit 1042 so as to display an image shown by image data stored in a storage unit 103 on the display unit 1042. A specification unit 201 acquires distance data showing a distance between a finger and an operated surface measured by a position detection unit 1041 and specifies a distance between the finger and the operated surface. When enlarging a displayed image, an image control unit 202 determines speed of enlargement corresponding to the distance specified by the specification unit 201 and enlarges the image at the determined speed. The display control unit 203 controls the display unit 1042 so as to display the enlarged image.
