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.
Claims15
An image sensing device comprising:
- a plurality of photoelectric conversion elements arranged in a line direction for each color of received light, the photoelectric conversion elements of one color being arranged in one line;
- and
- an analog-digital (AD) converter 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 being disposed in a position adjacent to each of the photoelectric conversion elements configuring the pixel group, each pixel group including photoelectric conversion elements for three different colors.
An image sensing method performed by an image sensing device comprising a plurality of photoelectric conversion elements arranged in a line 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 selected from the photoelectric conversion elements, the photoelectric conversion elements of one color being arranged in one line,
- the AD converter being disposed in a position adjacent to each of the photoelectric conversion elements configuring the pixel group, each pixel group including photoelectric conversion elements for three different colors.
An image sensing device comprising:
- a plurality of photoelectric conversion means arranged in a line direction for each color of received light, the photoelectric conversion means of one color being arranged in one line;
- and
- analog-digital (AD) conversion means for performing analog-digital conversion for each pixel group configured by a plurality of photoelectric conversion means selected from the plurality of photoelectric conversion means,
- the AD conversion means being disposed in a position adjacent to each of the plurality of photoelectric conversion means configuring the pixel group, each pixel group including photoelectric conversion means for three different colors.
