1. A method, comprising: receiving an input 3D image, the input 3D image comprising a first input image frame for a first perspective and a second input image frame for a second different perspective; wherein the 3D input image is a first 3D input image in a sequence of 3D input images comprising a second different 3D input image having a third input image frame for the first perspective and a fourth input image frame for the second perspective; generating, based on the first input image frame, reduced resolution image data for the first perspective; generating, based on the second input image frame, full resolution image data for the second perspective; encoding and outputting the reduced resolution image data and the full resolution image data to represent a first output 3D image, the first output 3D image comprising a pair of a reduced resolution output image frame derived from the reduced resolution image data for the first perspective and a full resolution output image frame derived from the full resolution image data for the second perspective; generating, based on the fourth input image frame, second reduced resolution image data for the second perspective; generating, based on the third input image frame, second full resolution image data for the first perspective; and encoding and outputting the second reduced resolution image data and the second full resolution image data to represent a second output 3D image, the second output 3D image comprising a second pair of a second reduced resolution output image frame derived from the second reduced resolution image data for the second perspective and a second full resolution output image frame derived from the second full resolution image data for the first perspective; wherein the presentation of full resolution output image frames in a sequence of output 3D input images comprising the first output 3D image and the second output 3D image alternates between the first and second perspectives; wherein between the first output 3D image based on the reduced resolution image data for the first perspective and the full resolution image data for the second perspective and the second output 3D image based on the second reduced resolution image data for the second perspective and the second full resolution image data for the first perspective, the spatial resolution of the image for the second perspective is gradually scaled down over a plurality of frames.
