Position detection apparatus, optical apparatus, image-taking system, position detection method and program

摘要

A position detection apparatus capable of carrying out position detection according to temperature variations is disclosed. The position detection apparatus comprises a first detection sensor which generates a plurality of detection signals according to movement of an object, a conversion section which generates a converted signal by subjecting at least one detection signal out of the detection signals to conversion processing using a conversion data obtained from the detection signal on, a calculation section which calculates a position of the object based on the converted signal and a second detection sensor which detects a temperature.
