Latest Patents

Han-Min Cheng holds a patent for an "Adaptive piece-wise approximation method for gamma correction." This method introduces an adaptive way to segment the brightness intensity input range. After segmentation, a set of selected sampling points is taken. A simplified gamma correction circuit is designed to eliminate the need for subtraction and division calculations in the gamma correcting function by appropriately choosing the segmentation points. The improved gamma correction circuit includes a multiplexer, a subtractor, an offset block, a multiplier, a division block, and an adder. An intensity signal at the selected input points is sampled, and the sampled values are stored to provide a top value and a bottom value for the video intensity to be gamma corrected. The video intensity value is then processed through the gamma correction circuit to produce a gamma-corrected data word representing pixel intensity for its respective input video intensity value.
