Claim 12:
13. The device according to claim 12, wherein the synthesizing the full depth-of-field images with the plurality of exposure values by using the HDR algorithm comprises:
calculating a synthesis weight of each pixel in the at least one foreground depth-of-field image with one of the plurality of exposure values based on a pixel value corresponding to each pixel in the foreground depth-of-field image;
calculating a synthesis weight of each pixel in the background depth-of-field image with the one of the exposure values based on a pixel value corresponding to each pixel in the background depth-of-field image; and
synthesizing obtained foreground depth-of-field images and background depth-of-field images with the plurality of exposure values based on the synthesis weight of each pixel in the at least one foreground depth-of-field images with the plurality of exposure values and the synthesis weight of each pixel in the at least one background depth-of-field images with the plurality of exposure values, to generate the high dynamic range image.
