Abstract:
1. An information processing apparatus configured to allow a touch operation thereon, the information processing apparatus comprising: an acquisition unit configured to acquire an angle between a straight line determined by two touch points at a first time point and a straight line determined by two touch points at a second time point; a setting unit configured to set an angular threshold value based on a distance between the two touch points at the first time point and a size of a target area of the touch operation included in the information processing apparatus; and a reception unit configured to receive an operational input performed with the two touch points as an operation for rotating an image displayed on a display device in a case where the angle acquired by the acquisition unit is greater than the angular threshold value set by the setting unit, wherein, the setting unit is configured to set the angular threshold value to a larger value as the distance between the two touch points at the first time point is shorter, and in a case where the distance between the two touch points at the first time point is the same and the size of the target area of the touch operation is different, the setting unit is configured to set the angular threshold value to a smaller value as the size of the target area of the touch operation is smaller.
