1. A method of generating a digital image, the method comprising:
obtaining, via a first electronic sensor, a plurality of images of a target within a time period;
selecting one or more pixels in a first image of the plurality of images;
identifying corresponding pixels, that correspond to the one or more selected pixels, in one or more other images of the plurality of images, the one or more selected pixels and the corresponding pixels defining sets of reference pixels;
identifying two or more images of the plurality of images with optimal disparity according to the sets of reference pixels;
generating modified depth information via the identified two or more images;
generating a final digital image via the modified depth information;
wherein generating the modified depth information includes:
determining disparity information for the identified two or more images; and
combining the determined disparity information with depth information from a second electronic sensor;
wherein generating the modified depth information includes downscaling the two or more identified images; and
determining the disparity information for the identified two or more images includes determining disparities via the downscaled versions of the two or more identified images;
wherein generating the modified depth information includes upscaling the combined disparity and depth information;
wherein generating the modified depth information includes:
shifting pixels of an image of the identified two or more images according to the upscaled combined disparity and depth information; and
determining remaining disparity information after the shifting;
wherein generating the modified depth information includes:
combining the remaining disparity information with the depth information; and
upscaling the remaining combined disparity and depth information; and
wherein the modified depth information includes the upscaled remaining combined disparity and depth information.
