ABSTRACT:
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. The plurality of photo-diodes is separated into a plurality of groups and each of the groups can be controlled independently. A distance measuring light beam having a predetermined pulse width is radiated to a measurement subject and a reflected light beam, generated by the measurement subject due to the distance measuring light beam, is sensed by the photo-diodes, so that a distance information sensing operation which detects distance information of the measurement subject is executed. In the distance information sensing operation, only predetermined groups of the photo-diodes are used for sensing the distance information, while in an image information sensing operation, which detects an image of the measurement subject, all photo-diodes in the CCD are used.
