Patent ID: 7307622

Claim:
A coordinate detection device, comprising: an input unit, having a surface thereof, to which a coordinate value is input by an input device; and a detection unit that determines an operation mode of said input unit, the detection unit further comprising: a calculation unit configured to calculate a distance between a final coordinate value of a previous input operation and a beginning coordinate value of a current input operation by said input unit so that an absolute coordinate value mode inputting operation is enabled in a relative coordinate value mode, the current input operation occurring after a detachment of the input device from the surface of said input unit during the immediately preceding previous input operation; wherein a coordinate value at a time when the input device is detached from the surface of said input unit is set as the final coordinate value of the previous input operation, and wherein the distance calculated by said calculation unit is transmitted to a host apparatus so as to prevent the current input operation from being connected to the previous input operation on a display, and wherein the absolute coordinate value mode inputting operation is enabled in the relative coordinate value mode based on a time during which the input device is detached from the surface of said input unit.
