PROBLEM TO BE SOLVED: To improve accuracy of determination of a player's body movement.SOLUTION: Position acquisition means (82) acquires three-dimensional position information from a position information generation means (10) for generating three-dimensional position information about a position of the player in the three-dimensional space on the basis of a taken image obtained by imaging means (12) for imaginging a player and depth information about intervals between a measurement reference position of depth measurement means (13) and the player. Determining means (84) determines whether a change of the player's position in the three-dimensional space meets operation determination criterion about the player's movement. Game processing execution means (86) executes game processing on the basis of a determination result of the determining means. The determining means (84) includes means for changing the operation determination criterion on the basis of the three-dimensional position information and determines whether or not a change of the player's position in the three-dimensional space meets the changed operation determination criterion.
