<p>PURPOSE: A control device and a control method for multi touch input cognition of a touch panel are provided to prevent the error recognition of touch input. CONSTITUTION: A touch sensor unit(300) generates a signal about the plane coordinates value of a spot which is selected by a touch input. When a first and second touch input are occurred, a controller(400) decides whether the first and second touch inputs are multi touch input or not. If the first and second touch input are the multi touch input, the operation unit(500) obtains the distance on the lateral axis of point-to-point. The operation unit uses the distance on the lateral axis and the plane coordinates value to calculate the coordinates of the first and second touch input spots.</p> |
