Abstract
A position detecting circuit detects an indicated position on an input surface of a sensor as absolute coordinates. A relative coordinate calculating circuit which, in operation, sequentially obtains the absolute coordinates from the position detecting circuit and calculates relative coordinates indicating the position indicated by an indicator on the input surface, from a difference between previous absolute coordinates and present absolute coordinates. An output absolute coordinate value calculating circuit which, in operation, assumes that an indication input is performed on an input area positioned on an output absolute coordinate region corresponding to a display screen, and calculates an output absolute coordinate value of the indicated position corresponding to the indication input by using the relative coordinates from the relative coordinate calculating circuit. The calculated output absolute coordinate value is output through an output circuit.
