Photoelectric conversion device and image sensor

摘要

To provide a small-area photoelectric conversion device without impairing a resolution switching function, signals for controlling output order control switches provided so as to correspond to photoelectric conversion elements are selected by an output order control circuit and a shift register. In this manner, the number of flip-flops forming a shift register is reduced.

1. A photoelectric conversion device, comprising:
a photoelectric conversion block including:
a plurality of photoelectric conversion elements for outputting electrical signals in accordance with incident light; anda plurality of capacitors for storing the electrical signals of the plurality of photoelectric conversion elements;a light reception signal control switch block including a plurality of light reception signal control switches for reading out the electrical signals stored in the plurality of capacitors to a common readout line;an output order control switch block including n units including j output order control switches for controlling an on and off state of the plurality of light reception signal control switches, where n and j are each a natural number of 2 or more;an output order control circuit for outputting an output order control signal for sequentially turning on the j output order control switches; anda shift register comprising n flip-flops circuits for outputting, to the n units, a shift register control signal for sequentially turning on the j output order control switches, where the number n of the flip-flop circuits is less than the number j of the output order control switch units.
