Latest Patents

One of Tsan-Hung Tsai's latest patents is a "System and method for contrast extension adjustment and overflow compensation of image signal." This invention provides a comprehensive system that includes contrast extension and overflow compensation look-up tables, an image gray level boundary determining unit, a contrast extension unit, an overflow judging unit, and an overflow compensation unit. The image gray level boundary determining unit defines a maximum and a minimum among the gray levels of the pixels of an image signal and calculates the difference. The contrast extension unit selects corresponding parameters from the contrast extension table for the contrast extension of a given image pixel. The overflow judging unit assesses whether the pixels are overflowed, while the overflow compensation unit compensates for the pixel. When a pixel is overflowed, the overflow compensation unit selects a corresponding overflow compensation parameter to reduce the gray level, effectively addressing the overflow issue.

Another significant invention is the "Hue adjusting device." This device allows users to adjust one color axis, which includes different hues, by rotating each of the different hue angles at varying rotation angles. As a result, the color of an image adjusted by this invention becomes smoother than in prior art, leading to improved image quality.
