COMPRESSION AND DECODING OF SINGLE SENSOR COLOR IMAGE DATA

摘要

A method is described to greatly improve the efficiency of and reduce the complexity of image compression when using single-sensor color imagers for video acquisition. The method in addition allows for this new image compression type to be compatible with existing video processing tools, improving the workflow for film and television production.

1. A method for decoding an encoded image, the method comprising:
storing encoded image data in a non-transitory computer-readable storage medium, the encoded image data representative of an original image at an original resolution, the original image comprising a plurality of image planes, the encoded image data comprising a set of encoded image planes each representative of one or more of the image planes of the original image; receiving a request for a preview of the original image, the requested preview comprising the original image at a preview resolution less than the original resolution; and in response to receiving the request for a preview of the original image:
accessing a subset of the set of encoded image planes, the subset comprising less than all of the set of encoded image planes; anddecoding, by a processor, the accessed subset of encoded image planes to produce the original image at the preview resolution.
