Latest Patents

Yeh’s listed patents address methods for processing grayscale data in display and image-processing systems.

Method for Outputting Grayscale Data, Driving Controller and Display Apparatus. This invention describes a method that handles grayscale values differently depending on their relationship to two thresholds. Values at or below the first threshold are output without dithering, while values above the second threshold undergo a dithering computation. The second threshold is higher than the first, and the resulting output for the latter values excludes portions of the input that were not processed by dithering.

Image Processing Circuit and Image Processing Method Thereof. This invention describes an image-processing circuit with a dithering circuit and a blending circuit. The dithering circuit generates dithered grayscale data, while the blending circuit compares the input data with a threshold to determine a blending weight. It then blends the original and dithered data to produce output grayscale data.
