Abstract
An image sensor includes a pixel array comprising a plurality of pixels, a color filter array comprising a plurality of color filter clusters overlying the pixel array, and readout circuitry configured to concurrently provide the pixels sharing the common filter cluster and having a first exposure time to a readout line for digital data conversion. Each of the color filter clusters includes a group of same color filters, and pixels sharing a common color filter cluster have different exposure times.
