PROBLEM TO BE SOLVED: To solve the problem that an operator can not operate a pointer as he or she intends in some cases because an output of a motion sensor in an input device may include error components of various factors relating to characteristics of the motion sensor.;SOLUTION: An image sensor is provided which images an input device to detect the position in an absolute coordinate system of the input device. A control apparatus corrects an output of the motion sensor which detects motion in the input device, in accordance with a relation between the output of the motion sensor and the position of the input device based on the image imaged by the image sensor. Thus operability can be improved while making use of advantages of a system using the motion sensor.;COPYRIGHT: (C)2011,JPO&INPIT
