Abstract: A digital pixel sensor for correcting and reducing a mismatch between a pixel and an analog digital converter provided. The digital pixel sensor includes a pixel array including a plurality of pixels; and a bank disposed on the pixel array. The bank includes: a plurality of comparators disposed on the plurality of pixels and configured to compare each of a plurality of pixel signals output from the plurality of pixels with a reference signal to output a plurality of comparison result signals; and a counter connected to the plurality of comparators, and configured to receive the plurality of comparison result signals and latch count code based on the plurality of comparison result signals.

Abstract: An image sensor includes a pixel array and a readout circuit. The pixel array includes a first unit pixel region including first, second and third sub-pixel regions having a first color filter, sequentially disposed along a first row line, and sharing a first floating diffusion region, and a second unit pixel region including a first, second and third sub-pixel regions having a second color filter, sequentially disposed along a second row line, and sharing a second floating diffusion region. The readout circuit includes a first analog-digital converter receiving a first pixel signal from the first unit pixel region through a first pixel signal output line and converting the first pixel signal into digital data, and a second analog-digital converter receiving a second pixel signal from the second unit pixel region through a second pixel signal output line and converting the second pixel signal into digital data, wherein at least one of the first unit pixel region and the second unit pixel region further includes a phase detection pixel region.
