Abstract: Disclosed is an imaging system with an image sensor; a wobulator that is to be employed to perform sub-pixel shifts when capturing images with the image sensor; and processor(s). The processor(s) is configured to, in each cycle, obtain two or three sub-images (504a-c) from the image sensor, wherein each sub-image in a same cycle has subsampled image data of at least a part of a field of view of the image sensor, the subsampled image data being subsampled according to a same subsampling pattern in the two or three sub-images of a given cycle; control the wobulator to perform one or two sub-pixel shifts; and process the two or three sub-images, to generate image(s).

Abstract: An imaging system including processor(s) and data repository. Processor(s) are configured to: receive images of region of real-world environment that are captured by cameras using at least one of: different exposure times, different sensitivities, different apertures; receive depth maps of region that are generated by depth-mapping means; identify different portions of each image that represent objects located at different optical depths; create set of depth planes corresponding to each image; warp depth planes of each set to match perspective of new viewpoint corresponding to which output image is to be generated; fuse sets of warped depth planes corresponding to two or more images to form output set of warped depth planes; and generate output image from output set of warped depth planes.
