IMAGE SENSORS

摘要

An image sensor includes a pixel array and a plurality of pairs of column lines. The pixel array includes a plurality of unit pixel areas arranged in a plurality of rows and columns. Each of the unit pixel areas includes a readout circuit connected to a corresponding pair of column lines, and first and second photo-electric conversion devices sharing the readout circuit. Each of the unit pixel areas is configured to output a first pixel signal corresponding to a photoelectron generated by the first photo-electric conversion device through the first column line, and to output a second pixel signal corresponding to a photoelectron generated by the second photo-electric conversion device through the second column line.

1. An image sensor comprising:
a pixel array including a plurality of unit pixel areas arranged in a plurality of rows and columns; and a plurality of pairs of column lines, each pair of column lines being aligned with a column among the plurality of columns, wherein each of the plurality of unit pixel areas includes,
a readout circuit connected to a corresponding pair of column lines, andfirst and second photo-electric conversion devices sharing the readout circuit; and wherein each of the plurality of unit pixel areas is configured to,
output, through a first column line among the corresponding pair of column lines, a first pixel signal corresponding to a first photoelectron generated by the first photo-electric conversion device, andoutput, through a second column line among the corresponding pair of column lines, a second pixel signal corresponding to a second photoelectron generated by the second photo-electric conversion device.
