Abstract

PURPOSE:To output a stable coordinate value without outputting an accidental abnormal value and caused by a noise, etc., by outputting a coordinate value which has been detected in the previous time, and a coordinate value which is detected this time, when a coordinate value difference is within prescribed value width, and when said difference is outside of the prescribed value width. CONSTITUTION:A difference between a coordinate value which has been detected in the previous time and a coordinate value which is detected this time is derived, and when its difference (coordinate value difference) is within prescribed value width, and in case when said difference is outside of the prescribed value width, the coordinate value which is detected in the previous time, and the coordinate value which is detected this time are outputted, respectively, and also, the coordinate value to be outputted is held as the coordinate value which is detected in the previous time with respect to the coordinate value which is detected in the next time. In such a way, a stable coordinate value can be outputted without outputting an accidental abnormal value caused by a noise, etc.
