Classification: CPC G  H | IPC H

Claim 0:
1. A high dynamic range image synthesis method, wherein the method comprises:
obtaining, based on a high dynamic range (HDR) photographing operation, a plurality of images with different depths of field in a current photographing scene, including generating at least one foreground depth-of-field image based on an initial foreground image from the plurality of images, and generating at least one background depth-of-field image based on an initial background image from the plurality of images, wherein each of the plurality of images, and each of the at least one foreground depth-of-field image, and each of the at least one background depth-of-field image has a respective exposure value;
generating full depth of field images, including, for each of the full depth of field images, synthesizing those of the plurality of images that have a same exposure value, to generate a respective one of the full depth-of-field images; and
synthesizing the full depth-of-field images with a plurality of exposure values by using an HDR algorithm, to generate a high dynamic range image.
