Patent ID: 8922678

Claim:
An image capturing apparatus, comprising: an image capturing module, for capturing a plurality of temporal images; and a processing module, for setting one of the temporal images as a base image, dividing each of the temporal images into a plurality of temporal image blocks, and dividing the base image into a plurality of base image blocks, and determining whether or not a difference between each of the temporal image blocks and each of the corresponding base image blocks is smaller than a threshold value; wherein the processing module performs an image combination by using the temporal image block and the corresponding base image block to generate an output image when the difference between one of the temporal image blocks and one of the base image blocks is smaller than the threshold value, and the processing module further performs a geometric alignment of each of the base image blocks with each of the corresponding temporal image blocks, and calculates a first error value, such that the processing module combines the base image block with the corresponding temporal image block if the first error value is smaller than the threshold value.
