IMAGE SENSOR AND IMAGE SENSOR SYSTEM INCLUDING THE SAME

摘要

An image sensor includes a pixel array, a microlens array, and a plurality of polarization filters. The pixel array includes a plurality of pixels. The microlens array is arranged on the pixel array. The microlens array includes a plurality of microlenses which overlap the pixel group of the pixel array. The polarization filters are arranged on the microlenses. The polarization filters have at least two different polarization phases. Therefore, the present invention improves the reliability and accuracy of local auto white balancing.
