Zusammenfassung:PROBLEM TO BE SOLVED: To improve operability by using three-dimensional position information of an instruction object to devise screen display.SOLUTION: A control unit converts an intra-input surface position, which is a position right below an instruction object along a normal of an input surface of an input device, in the input surface to an intra-display surface position of a display device on the basis of three-dimensional information of the instruction object (two-dimensional position conversion processing). The control unit determines whether a distance from the input surface to the instruction object along the normal of the input surface corresponds to one of a plurality of preliminarily determined distance levels or not on the basis of the three-dimensional information (distance level determination processing). The control unit changes representation of a prompt 31 displayed on a display surface of the display device in accordance with the distance level determined by the distance level determination processing (prompt representation setting processing). The control unit generates display image data for displaying the prompt 31 in the intra-display surface position obtained by the two-dimensional position conversion processing and with the representation set by the prompt representation setting processing.
