ABSTRACT:
The invention provides a camera photometry system that uses accumulation-type photometry elements to output photometric information related to the brightness of the subject field. The invention eliminates the smear phenomenon caused by the effects of the brightest parts of the subject field while also appropriately measuring the light of the major subject in the subject field. The invention is a camera photometry system equipped with a photometry mechanism which measures light using accumulation-type photoelectric elements by dividing the subject field into multiple photometry regions, and which outputs photometry information related to the brightness of the subject field, with the photometry element being equipped with a photoelectric mechanism for converting light into electricity which is stored and a transmission mechanism for transmitting the electric charge which is stored by the photoelectric mechanism. The system is configured so that the transmission mechanism transmits the electric charge from the top to the bottom with respect to the vertical direction of the subject field.
