Latest Patents

One of his latest patents is titled "Pseudo-fixed length image compression scheme." This invention presents a method and apparatus for efficient image encoding in predictive coding or other error-based image compression schemes. A pseudo-fixed length code is employed to convert certain calculated error values into codewords. The code is considered pseudo-fixed length since the length of codewords is fixed for a particular range of values and then increased for the next range. The length of codewords is not needed in decoding by choosing prefixes that uniquely distinguish codewords when packed together. As a result, efficient and quick image encoding and decoding are made possible.

Another significant patent is the "Method and apparatus for rapid down-scaling of color images directly from sensor color filter array space." This method involves downscaling an image from a sensor color filter array space, beginning with the determination of an initial image size. The method also includes steps for determining a set of stride lengths, locating a single color pixel of interest, and generating a full-color pixel. An apparatus featuring a processor and memory coupled to the processor is disclosed for performing these steps.
