Abstract
Various embodiments are generally directed to techniques for reducing the consumption of electric power in rendering an image onto a display associated with a computing device by generating and compressing difference frames for use in rendering the image. A device to compress video frames includes a processor component; and a frame buffer compressor for execution by the processor component to compress a current frame of a series of frames as a compressed difference frame, the compressed difference frame comprising a difference frame that indicates a difference in pixel color of at least one pixel between the current frame and a preceding adjacent frame of the series of frames. Other embodiments are described and claimed.

1-25. (canceled)
A device to compress video frames comprising:
- a processor component;
- a storage communicatively coupled to the processor component;
- and
- a frame buffer compressor for execution by the processor component to compress a current frame of a series of frames as a compressed difference frame and store the compressed difference frame in the storage, the compressed difference frame comprising a difference frame that indicates a difference in pixel color of at least one pixel between the current frame and a preceding adjacent frame of the series of frames.
A device to visually present video frames comprising:
- a processor component;
- a storage communicatively coupled to the processor component;
- a display buffer decompressor for execution by the processor component to retrieve a compressed difference frame of a series of compressed frames from the storage and decompress the compressed difference frame to generate a difference frame that indicates a difference in pixel color of at least one pixel between a current frame and a preceding adjacent frame to enable reconstruction of the current frame;
- and
- a presentation component for execution by the processor component to visually present the current frame on a display.
A computer-implemented method for compressing video frames comprising:
- compressing a current frame of a series of frames by compressing a difference frame to generate a compressed difference frame;
- subtracting pixel color values of one of the current frame and a preceding adjacent frame of the series of frames from corresponding pixel color values of another of the current frame and the preceding adjacent frame to derive the difference frame;
- and
- storing the compressed difference frame in a compressed frame buffer.
At least one machine-readable storage medium comprising instructions that when executed by a computing device, cause the computing device to:
- compress a current frame of a series of frames by compressing a difference frame to generate a compressed difference frame;
- and
- subtract pixel color values of one of the current frame and a preceding adjacent frame of the series of frames from corresponding pixel color values of another of the current frame and the preceding adjacent frame to derive the difference frame.
