WIDE DYNAMIC RANGE IMAGE SENSOR

摘要

An image sensor having a broad operation range obtains images each having a different exposure degree through a pair of pixels each having a different exposure degree, and combines the images to generate an image having a broad luminance range. The image sensor comprises a pixel array where a plurality of unit pixel groups each including a plurality of pixels each having a different exposure time are arranged in a lattice type, a row driver configured to generate a driving signal required in the operation of the pixel array, and an output circuit configured to receive a sensing signal outputted from the pixel array so as to separate signals of an even number column from those of an odd number column in each unit pixel group.
