Abstract
A photographic optical device may include a reflection type optical sensor comprising a light emitting element and a light receiving element; a support body to which the reflection type optical sensor is fixed; a camera module comprising a lens and an imaging element; a shake correction mechanism structured to swing the camera module; a resistor configured to convert an output current of the light receiving element to an output voltage; a home position voltage creating means configured to create a home position voltage; a comparator configured to compare the home position voltage with a predetermined reference voltage; and a variable current source configured to control an electric current supplied to the light emitting element based on an output signal from the comparator. A relative position of the camera module with respect to the support body may be detected by the reflection type optical sensor.
