ABSTRACT:
A photo-electric converting device includes storing parts which store electric charges obtained through a photo-electric conversion process respectively from reflected light received when light projection is performed by light emitting apparatus and another reflected light received when no light is projected by the light emitting apparatus. The device computes storage signals produced from the storing parts and detects an electric signal which corresponds solely to reflected light resulting from light projection performed by the light emitting apparatus.
