Abstract
An image calibrating method for stitching images includes calculating contrast values of a plurality of images, and comparing the contrast values to set the image with maximal contrast value as a reference image; others of the plurality of images are set as target images. The image calibrating method further includes calculating cumulative distribution functions of the reference image and the target images respectively, and obtaining a transform function according to the cumulative distribution functions of the reference image and the target images for pixel adjustment of the target images. Further, a camera with an image calibrating function and a related image processing system are disclosed in the present invention.
