A three-dimensional image capturing device comprises an imaging device, such as a CCD, having a plurality of photo-diodes, a vertical transfer unit and a substrate. First and second electric charge discharging signals and an electric charge transfer signal are periodically output, respectively. Due to the first electric charge discharging signal, unwanted charge accumulated in the photo-diodes is discharged to the substrate. An output of the electric charge transfer signal is started before the end of the output of the first electric charge discharging signal, and ends after the start of the output of the second electric charge discharging signal. A reflected light beam, generated by a measurement subject due to a distance measuring light beam, is sensed by the photo-diodes. Due to the second electric charge discharging signal, the electric charge accumulation in the photo-diodes ends.
