Abstract: A game device is provided. The game device includes a first execution section, a game screen updating section, and a game situation data acquiring section. In the case where a first execution time which comes every first time period is reached, the first execution section generates game situation data. In the case where a second execution time which comes every second time period is reached, the game screen updating section updates a game screen based on game situation data corresponding to an attention time which comes a time period before the second execution time. The game situation data acquiring section acquires the game situation data corresponding to the attention time by executing interpolation processing based on first game situation data corresponding to a time which comes before the attention time and second game situation data corresponding to a time which comes after the attention time.

Abstract: To provide a game device capable of reducing a workload of a game developer in developing a game (game program) compatible with a plurality of game devices having different execution intervals of game processing. In the case where a first execution time which comes every first time period is reached, first execution section (62) generates game situation data. In the case where a second execution time which comes every second time period is reached, game screen updating section (64) included in second execution section updates a game screen based on game situation data corresponding to an attention time which comes a predetermined time period before the second execution time. Game situation data acquiring section (66) acquires the game situation data corresponding to the attention time by executing interpolation processing based on first game situation data corresponding to a time which comes before the attention time and second game situation data corresponding to a time which comes after the attention time.

Abstract: To provide an image processing device capable of assisting a user to readily recognize bumps and recesses of an object. An original texture image storage unit (82) stores an original texture image for an object. A second display control unit (88) displays, on a display unit, an image showing a picture obtained by viewing an object having an auxiliary-lined texture image mapped thereon from a viewpoint, the auxiliary-lined texture image being formed by drawing a plurality of auxiliary lines forming a mesh or a plurality of parallel auxiliary lines on an original texture image.
