Patent ID: 8760530

Claim:
An image capturing apparatus, comprising: an image capturing module, capable of capturing a plurality of temporal images; and a processing module, capable of setting one of the temporal images as a base image, and determining whether or not a difference between the remaining temporal images and the base image is greater than a threshold value; wherein if the difference between one of the remaining temporal images and the base image is greater than the threshold value, the processing module deletes the temporal image of the remaining temporal images, and performs an image combination to the rest of the remaining temporal images with the base image to correspondingly generate an output image, wherein the threshold value comprises a first threshold value and a second threshold value, wherein the processing module performs a geometric alignment of the base image with each of the remaining temporal images and correspondingly calculates a first error value, such that the processing module deletes the temporal image of the remaining temporal images if the first error value is greater than the first threshold value, wherein the processing module uses a histogram of the base image and each of the remaining temporal images to determine whether or not a second error value between the temporal image of the remaining temporal images and the base image is greater than the second threshold value, such that the processing module deletes the temporal image of the remaining temporal images if the second error value is greater than the second threshold value.
