Abstract
There is provided an image sensor for exposing a plurality of pixel rows within a frame period using a rolling shutter. The image sensor includes a processor for calculating bright-dark distribution patterns of image frames. The processor further adjusts the frame period to be substantially identical to a predetermined period by changing a total number of exposed line times within the frame period when a difference between the bright-dark distribution patterns of two image frames is larger than a predetermined threshold.
