Abstract
Provided is a pixel array having a wide dynamic range, good color reproduction, and good resolution and an image sensor using the pixel array. The pixel array includes a plurality of first type photodiodes, a plurality of second type photodiodes, and a plurality of image signal conversion circuits. A plurality of the second type photodiodes are disposed between the first type photodiodes which are two-dimensionally arrayed. A plurality of the image signal conversion circuits are disposed between the first type photodiodes and the second type photodiodes to process image signals detected by the first type photodiodes and the second type photodiodes. An area of the first type photodiodes is wider than an area of the second type photodiodes.
