If a corresponding area that is an area in a touch sensor related with an option is set larger than the size of a displayed option and corresponding areas related with different options overlap each other, any user-selected options may be properly identified. A processing execution block controls such that an option is displayed on a display block. An option identification block identifies, if a detection corresponding position that is a position in the display block related with a detected position detected by a touch sensor is inside an area in which a corresponding area that is an area including an area in which an option is displayed overlaps two or more options, any of these two or more options on the basis of a positional relation between said detection corresponding position and a corresponding area for each of these two or more options.
