PROBLEM TO BE SOLVED: To provide a technique which can eliminate a restrictive requirement that an input surface of an input device and a display surface of a display device must be designed into similar figures.SOLUTION: A control unit sets a prompt display area 2b in a display surface 2a (prompt display area setting processing). The control unit converts an intra-input surface position (x0,y0) to an intra-display surface position (X0,Y0) being a corresponding position in the prompt display area 2b, in accordance with a conversion rule which is defined so that a positional relation between an input surface 4a and the intra-input surface position (x0,y0) is maintained in a positional relation between the prompt display area 2b and the intra-display surface position (X0,Y0) (two-dimensional position conversion processing). The control unit generates display image data for displaying a prompt 31 in the intra-display surface position (X0,Y0) obtained by the two-dimensional position conversion processing (display image data generation processing). |
