Abstract
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.

A method for previewing captured image data, the method comprising:
- capturing, by an image sensor of a camera, image data, the image data comprising a plurality of image planes;
- encoding, by an image processor, the captured image data into a plurality of encoded image planes, each encoded image plane representative of one or more of the image planes of the image data, such that all of the encoded image planes form an image at a first resolution and a subset of less than all of the encoded image planes form an image at a second resolution less than the first resolution;
- and
- providing, to an external display, the subset of the encoded image planes for a substantially real-time preview of the image at the second resolution, the external display configured to decode the subset of encoded image planes to obtain the image at the second resolution.
A system for previewing captured image data, the system comprising:
- an image sensor configured to capture image data, the image data comprising a plurality of image planes;
- an image processor configured to encode the captured image data into a plurality of encoded image planes, each encoded image plane representative of one or more of the image planes of the image data, such that all of the encoded image planes form an image at a first resolution and a subset of less than all of the encoded image planes form an image at a second resolution less than the first resolution;
- an output to provide, to an external display, the subset of the encoded image planes for a substantially real-time preview of the image at the second resolution, the external display configured to decode the subset of encoded image planes to obtain the image at the second resolution.
A non-transitory computer-readable storage medium storing computer-readable instructions that, when executed by a hardware processor, cause a camera system to perform steps comprising:
- capturing, by an image sensor of a camera system, image data, the image data comprising a plurality of image planes;
- encoding, by an image processor of a camera system, the captured image data into a plurality of encoded image planes, each encoded image plane representative of one or more of the image planes of the image data, such that all of the encoded image planes form an image at a first resolution and a subset of less than all of the encoded image planes form an image at a second resolution less than the first resolution;
- and
- providing, to an external display, the subset of the encoded image planes for a substantially real-time preview of the image at the second resolution, the external display configured to decode the subset of encoded image planes to obtain the image at the second resolution.
