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

  • (2) The “another” pixel(s) 10 may be a first pixel (the pixel 10 (2, 1) in FIG. 3) and “multiple” pixels 10 among the plurality of pixels 10 include a second pixel and a third pixel (the pixel 10 (1, 1), and the pixel 10 (3, 1) in FIG. 3) disposed on the two opposite sides of the first pixel. Thus, a signal with a weight applied to the pixel signal from the central pixel can be obtained by combining pixel signals from a plurality of pixels. This, in turn, makes it possible to generate image data based upon pixel signals each generated by incorporating the pixel signals from the pixels located around (above and below) the pixel located at the central position with the pixel signal from the central pixel. As a result, weight will be applied to pixels located at consistent positions, which makes it possible to prevent the quality of an image generated by using the pixel signals from becoming poor.
