Latest Patents

Lamb holds a patent for a "Method and system for decoding encoded images and reducing the size of said images." This invention focuses on reducing the number of mathematical operations required in the JPEG decoding process without substantially impacting the quality of the displayed image. The method provides an efficient JPEG decoding process, especially for displaying images on screens smaller than the source image. By reducing the processing required for dequantization and inverse DCT (IDCT), the invention effectively discards unnecessary DCT index rows and columns prior to these processes. This allows for only the top left portion of the block of quantized and DCT coefficients to be processed, optimizing performance.
