Abstract
An improved scalar embedded graphics coding (EGC) for wireless HD compression is described herein. The image frame to be encoded is divided into blocks, which are further divided into color groups. These groups are encoded one bit plane at a time. The improved scalar EGC method and system uses shared grouping data among color components, but bit planes of each color are separately encoded. Further, during encoding a second-level grouping is able to occur on the splitting signaling of the groups. The system and method described herein retain the simplicity of scalar EGC and attain an efficiency comparable to vector EGC.

A method of compression programmed in a controller in a device comprising:
- a. partitioning an image into blocks;
- b. separating the blocks into groups, wherein the groups are based on shared data of the groups among color components;
- and
- c. encoding the groups separately for each bit plane using splitting signaling.
A system for compression programmed in a controller in a device, the system comprising:
- a. a partitioning module for partitioning an image into blocks;
- b. a separating module for separating the blocks into groups, wherein the groups are based on shared data among color components;
- and
- c. an encoding module for encoding the groups separately for each bit plane using splitting signaling.
A camera device comprising:
- a. a video acquisition component for acquiring a high definition video;
- b. a memory for storing an application, the application for:
- i. partitioning an image of the video into blocks;
- ii. separating the blocks into groups, wherein the groups are based on shared data of the groups among color components;
- and
- iii. encoding the groups separately for each bit plane using splitting signaling;
- and
- c. a processing component coupled to the memory, the processing component configured for processing the application.
