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.

-21. (canceled)
A method for compressing an image, comprising:
- receiving raw sensor data that has been captured by an imaging sensor, the raw sensor data comprised of a plurality of arrays of imaging components, each of the plurality of arrays configured to generate a first imaging component, a second imaging component, a third imaging component and a fourth imaging component;
- summing the second imaging component with the third imaging component in order to generate a first modified image plane;
- subtracting the third imaging component from the second imaging component in order to generate a second modified image plane;
- subtracting the first modified image plane from at least the first imaging component in order to generate a third modified image plane;
- subtracting the first modified image plane from at least the fourth imaging component in order to generate a fourth modified image plane;
- and
- outputting the first, second, third, and fourth modified image planes.

A computer readable apparatus comprising a storage medium adapted to store a computer program, the computer program which, when executed, is configured to:
- receive raw sensor data that has been captured by an imaging sensor, the raw sensor data comprised of a plurality of arrays of imaging components, each of the plurality of arrays configured to generate a first imaging component, a second imaging component, a third imaging component and a fourth imaging component;
- sum the second imaging component with the third imaging component in order to generate a first modified image plane;
- subtract the third imaging component from the second imaging component in order to generate a second modified image plane;
- subtract the first modified image plane from at least the first imaging component in order to generate a third modified image plane;
- subtract the first modified image plane from at least the fourth imaging component in order to generate a fourth modified image plane;
- and
- output the first, second, third, and fourth modified image planes.
4 more elements
An imaging decoder system, comprising:
- an input configured to receive four quarter-resolution planes, the four quarter-resolution planes comprising:
- a first modified image plane, the first modified image plane comprising a sum of a second imaging component with a third imaging component;
- a second modified image plane, the second modified image plane comprising a subtraction of the third imaging component and the second imaging component;
- a third modified image plane, the third modified image plane comprising a subtraction of a first imaging component from the first modified image plane;
- and
- a fourth modified image plane, the fourth modified image plane comprising a subtraction of a fourth imaging component from the first modified image plane;
- and
- a decoder apparatus, the decoder apparatus configured to reconstruct the four quarter-resolution planes into:
- (i) a first image that is a quarter of its native resolution, and/or (ii) a second image that comprises the native resolution.
