Solid-state image sensor and camera

A camera comprising:

• a solid-state image sensor comprising a pixel array including a light-receiving pixel having a first photoelectric converter, a second photoelectric converter and one microlens provided in common for both the first photoelectric converter and the second photoelectric converter, and a light-shielded pixel having a third photoelectric converter and a fourth photoelectric converter, and a processor configured to process a signal from the pixel array;
• and
• a processing unit configured to perform a processing based on output from the solid-state image sensor,
• wherein in a period, the processor holds (a) a first signal corresponding to charges of the first photoelectric converter, (b) a second signal corresponding to a sum of charges of the first photoelectric converter and charges of the second photoelectric converter, and (c) a third signal corresponding to a sum of charges of the third photoelectric converter and charges of the fourth photoelectric converter, and
• wherein the processor outputs (a) a signal associated with the first signal held in the period, (b) a signal associated with the second signal held in the period, and (c) a signal associated with the third signal held in the period, and does not output (d) a signal corresponding to charges of the third photoelectric converter and a signal corresponding to charges of the fourth photoelectric converter.
