Title: The Innovations of Thomas R. Craver
Introduction
Thomas R. Craver is an accomplished inventor based in Cranbury, NJ (US). He holds two patents that showcase his expertise in display processing technology. His work has significantly contributed to advancements in image data processing.
Latest Patents
Craver's latest patents include a display processor for image data with non-constant pixel size. This invention is embodied in a system comprising image memory and a display processor that automatically processes video data. The system alternates between having chrominance pixels of greater area than luminance pixels and having chrominance pixels of the same area as luminance pixels. Subsamples describing chrominance pixels of greater size are time-division-multiplexed with samples describing pixels in the image memory output when the former type of processing is done. The channel for reading subsamples from image memory to the display processor is used to transmit flag data controlling the mode of processing of video data performed by the video processor.
Another notable patent is a display processor with color matrixing circuitry and two map memories. This display processor uses first and second chrominance map memories for storing values of first and second color-difference signals, each normalized respective to the luminance signal. An image memory supplies data at pixel scan rate, which is used to provide read-addresses to the first and second chrominance map memories and data used to describe the luminance signal. The first and second chrominance map memory read-outs are multiplied by the luminance signal of appropriate spatial bandwidth to generate descriptions of the first and second color-difference signals in non-normalized form. These signals are supplied to color matrixing circuitry, which responds to provide red, green, and blue drive signals to display apparatus.
