Abstract
A photo detecting device includes an output line leading to a processing circuit, and an array of pixels including respective photo detecting zones for changing incident light into corresponding electric signals through photoelectric conversion. Each of the pixels includes a first switch for selectively connecting and disconnecting a related photo detecting zone to and from the output line, and a second switch for selectively connecting and disconnecting the related photo detecting zone to and from a ground line. The second switch disconnects the related photo detecting zone from the ground line when the first switch connects the related photo detecting zone to the output line. The second switch connects the related photo detecting zone to the ground line when the first switch disconnects the related photo detecting zone from the output line.
