PROBLEM TO BE SOLVED: To provide a seamless user interface by unifying time series direction when displaying a representative image of a content file on a calendar having respective temporal axis ranges of the year, the month and the day. SOLUTION: When an operation reception part 170 receives left click operation, a control part 180 changes over the temporal axis range such that the temporal axis range is finely divided according to a unit (yearly in the case of a year display screen, monthly in the case of a month display screen, or a daily in the case of a day display screen) of the selected temporal axis range. When the operation reception part 170 receives right click operation, the control part 180 changes over the temporal axis range such that the temporal axis range becomes rough. The temporal axis range and a position to be displayed in the calendar are held in a display state holding part 190 as a display state. The calendar continues across years, months or days, and seamless display is performed across years, months or days when the operation reception part 170 receives scroll operation.
