Abstract
A signal processing unit (C, C, C) for processing a light reception signal from an imaging element () at different magnifications is provided in a light receiving unit () in a displacement sensor (). This sensor () measures a displacement by using light receiving amount data generated by the signal processing unit (C) for each detection processing by a light projecting unit () and the light receiving unit (), and further adjusts sensitivity for next detection processing. In sensitivity adjustment processing, when a peak value in the light receiving amount data generated by the signal processing unit (C) approximates to 0, a peak value extracted by the signal processing unit (C) to which higher magnification is applied is employed. Alternatively, when a peak value in the light receiving amount data generated by the signal processing unit (C) is saturated, a peak value extracted by the signal processing unit (C) to which 1-fold magnification is applied is employed.
