Abstract
An image sensing device includes a plurality of photoelectric conversion elements arranged in one direction for each color of received light, and an analog-digital (AD) convertor that performs analog-digital conversion for each pixel group configured by a plurality of photoelectric conversion elements selected from the photoelectric conversion elements. The AD converter is disposed in a position adjacent to each of the photoelectric conversion elements configuring the pixel group.

(canceled)
An image sensing device comprising:
- a plurality of photoelectric conversion elements arranged in one direction for each color of received light;
- and
- an analog-digital (AD) converter that performs analog-digital conversion for each pixel group configured by a plurality of photoelectric conversion elements for a same color selected from the photoelectric conversion elements,
- the AD converter being disposed in a position adjacent to each of the photoelectric conversion elements configuring the pixel group.
An image forming apparatus comprising:
- the image reading device that includes an image sensing device including
- a plurality of photoelectric conversion elements arranged in one direction for each color of received light, and
- an analog-digital (AD) converter that performs analog-digital conversion for each pixel group configured by a plurality of photoelectric conversion elements for a same color selected from the photoelectric conversion elements,
- the AD converter being disposed in a position adjacent to each of the photoelectric conversion elements configuring the pixel group;
- and
- circuitry configured to form an image read by the image reading device.
An image sensing method performed by an image sensing device comprising a plurality of photoelectric conversion elements arranged in one direction for each color of received light, the method comprising:
- performing, by an analog-digital (AD) converter, analog-digital conversion for each pixel group configured by a plurality of photoelectric conversion elements for a same color selected from the photoelectric conversion elements,
- the AD converter being disposed in a position adjacent to each of the photoelectric conversion elements configuring the pixel group.
