Abstract
A position detection apparatus which can control an apparatus to be controlled, such as a motor or the like, more precisely, is disclosed. When a predetermined time has passed since reception of a request signal for requesting output of the position data was detected, the position detector measures the output of a sensor for detecting the position of an object to be measured, and calculates the position data representing the position of the object at a point of time when the measurement was performed, based on the measured output. Moreover, the position detector measures the reception interval of the request signal, calculates the corrected position data representing the position of the object at the time of receiving the request signal whose reception interval was measured, using a value obtained by subtracting the predetermined time from the measured reception interval, the calculated position data, and a change rate in a presumed position of the object, and outputs the corrected position data as a response to the request signal.
