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(shuō)明書(shū)

  • (3) A plurality of pixels 10 are arranged along the column direction designated as a first direction and along the row direction designated as a second direction. The plurality of pixels 10 include first, second and third pixels disposed in a first column and first, second and third pixels disposed in a second column, with a first signal line and a second signal line (first and second vertical signal lines VL1 and VL2) disposed in correspondence to each of the first and second columns. An arithmetic unit 50 executes an arithmetic operation with signals output to the first and second signal lines corresponding to the first column and signals output to the first and second signal lines corresponding to the second column. As a result, signals from the plurality of pixels 10 arranged along the column direction and along the row direction can be combined. In addition, it is possible to prevent that a weight is applied to a pixel signal from a pixel with the FD thereof achieving a high potential irrespective of the position of pixel, when combining a plurality of pixel signals.

    • The following variations are also within the scope of the present invention, and one of the variations or a plurality of variations may be adopted in combination with either of the embodiments described above.
