Japanese Patent JP2012068253
Kind Code:
A
Abstract:

To prevent lowering of photometric accuracy without troublesome calculation and the like.

A photoelectric conversion device includes: a photoelectric converter 1 for separating a field into a plurality of photometric regions, and generating and accumulating charge proportional to light intensity; transfer means 2 for transferring the charge accumulated in the photoelectric converter 1; charge/voltage conversion means 5 and 21 for holding the charge transferred from the transfer means 2 and converting the charge into voltage; reset means 6 for resetting the charge/voltage conversion means 5 and 21 to a reference level; transfer means 3 for not transferring the charge accumulated in the photoelectric converter 1 to the charge/voltage conversion means 5 and 21; and charge exhausting means 7 and 8 for exhausting the charge transferred by the transfer means 3.
