20 Claims

1. A processor comprising:

one or more circuits to:

separate sensor data representative of a frame in a first raw image color space into a first frame layer corresponding to at least one first color element of the first raw image color space and a second frame layer corresponding to at least one second color element of the first raw image color space;

reconfigure the first frame layer and the second frame layer into a pseudo color space expression corresponding to a second raw image color space different from the first raw image color space, the pseudo color space expression including a first frame storing the at least one first color element and a second frame storing the at least one second color element;

compress the first frame and the second frame according to a compression algorithm associated with the second raw image color space to generate compressed frame data; and

store the frame using the compressed frame data.
