摘要

An image sensor, includes: a plurality of pixels arranged along a first direction, each of which includes a photoelectric conversion unit that generates an electric charge through photoelectric conversion of light, and outputs a signal generated based upon the electric charge generated in the photoelectric conversion unit; a first signal line to which signals from one or more pixels among the plurality of pixels are output; a second signal line to which a signal from another pixel among the plurality of pixels is output; and an arithmetic unit that executes an arithmetic operation with a signal generated by combining the signals from the one or more pixels output to the first signal line and the signal output to the second signal line.

說明書

Furthermore, as the second selection unit 17 in the pixel 10 (2, 1) in the first column, the second selection unit 17 in the pixel 10 (2, 3) in the third column and the switch SW46 enter an ON state, the source terminals of the amplifier units 15 in the pixel 10 (2, 1) and the pixel 10 (2, 3) become electrically connected. The electric current from the second electric current source 26a connected to the second vertical signal line VL2a is shunted and distributed to the pixel 10 (2, 1) and the pixel 10 (2, 3). A combined pixel signal generated by combining the pixel signals from the two pixels 10 (2, 1) and 10 (2, 3) is output on the second vertical signal line VL2a and the second vertical signal line VL2c.

As the second selection unit 17 in the pixel 10 (2, 2) at the central position set in an ON state, the amplifier unit 15 of the pixel 10 (2, 2) becomes electrically connected to the second vertical signal line VL2b. The electric current from the second electric current source 26b in its entirety flows to the pixel 10 (2, 2). The pixel signal from the pixel 10 (2, 2) is output on the second vertical signal line VL2b.
