1. A program stored in a non-transitory computer-readable information storage medium, the program controlling an image displayed on a display screen of a display section based on a detection value output from a detection section, the detection section outputting the detection value corresponding to a first position when an operation state of a touch operation performed on an operation surface is a first operation state in which a first touch operation is performed at the first position on the operation surface, and outputting the detection value corresponding to a midpoint between the first position and a second position when the operation state is a second operation state in which a second touch operation is performed at the second position on the operation surface in addition to the first touch operation, the program causing a computer to function as:

  • an acquisition section that acquires a detected position based on the detection value, the detected position indicating a position on the operation surface;

    a state determination section that determines whether the operation state is the first operation state or the second operation state based on the detection value;

    a correction section that calculates a corrected position when the operation state is the second operation state, one endpoint being indicated by the detected position acquired in the first operation state, a midpoint being indicated by the detected position acquired in the second operation state, and the other endpoint being indicated by the corrected position; and

    a display control section that controls the image based on the corrected position.
