Abstract: An image sensor includes a pixel array, a micro lens array and polarizing filters. The pixel array includes a plurality of pixels. The micro lens array is disposed on the pixel array and includes a plurality of micro lenses. The micro lens overlaps a pixel group of the pixel array. The polarizing filter is disposed on the micro lens and includes a plurality of polarizing filters having at least two different polarizing phases. Accordingly, the accuracy and the reliability of the local auto white balancing may be improved.

Abstract: A white balancing device and a method of driving the same are provided. The white balancing device includes a map generator and an automatic white balancing (AWB) block. The map generator is configured to generate an indoor-outdoor map comparing a first image and a second image generated by performing a wide dynamic range (WDR) algorithm on the first image. The AWB block is configured to generate a first white point with respect to an outdoor region and a second white point with respect to an indoor region using the indoor-outdoor map.
