ABSTRACT:
In the disclosed photo-electric conversion device, a light source repetitiously emits light and a photo-electric converter receives reflected light originally generated by the source and ambient light. A first store stores the output of the photo-electric converter when the light source emits light and a second store stores data from the photo-electric converter when the source does not emit light. A gate transfers the output from the converter to the first and second stores. A pulse generator controls the gate for transferring the converter output to the first store and the second store during every light emitting cycle of the light source.
