Abstract: CMOS image sensor with multiple sensitivities for high dynamic range imaging and LED flicker mitigation. In one embodiment, an image sensor includes a plurality of pixels arranged in rows and columns of a pixel array that is disposed in a semiconductor substrate. Each pixel includes a plurality of cells. A plurality of color filters is disposed over corresponding plurality of cells. The plurality of color filters corresponding to the plurality of cells of an individual pixel have more than one filtering strength for each color of the plurality of color filters.
