Claim Text:
1. An image sensor system comprising: an image sensor that generates signals representing an input image, the image sensor comprising: a signal processor operatively connected to the image sensor and configured to generate a plurality of polarized sub images based on the input image and to conduct an auto white balancing process based on the polarized sub images, wherein the signal processor comprises: a polarized sub image generating part configured to generate the polarized sub images based on the input image, a light source characteristic determining part configured to determine a characteristic value of a light source corresponding to a difference between the polarized sub images, a depth determining part configured to determine a depth of the input image based on the polarized sub images, and a local auto white balancing part configured to conduct local auto white balancing based on the characteristic value of the light source and the depth.
