Abstract:
1. A method for demultiplexing a multiplexed single frame divided into portions, the multiplexed single frame comprising a first image in a first portion and a second image in a second portion, wherein at least the first image is a first scaled image that was scaled from a first original image, the first scaled image having a central portion and an edge portion, the central and edge portions of the first scaled image having been downscaled by first and second scaling factors, respectively, wherein the first and second scaling factors are both less than one, and wherein an aspect ratio of the first original image and an aspect ratio of the multiplexed single frame are substantially the same, the method comprising: receiving the multiplexed single frame comprising the first scaled image; generating a first demultiplexed image from the first scaled image, wherein generating comprises reverse variable scaling the central portion and the edge portion of the first scaled image by a first inverse scaling factor and a second inverse scaling factor, respectively, the first and second inverse scaling factors being different; and generating a second demultiplexed image from the second image in the multiplexed single frame; wherein all of the reverse scaling factors are greater than one.
