摘要： The method to reduce image sticking in a plasma display panel (PDP) includes four steps. There is converting a relationship between gray level and brightness of an input signal into a linear relation by a converter. Next, there is recording an image with a static image detector at time t using a frame buffer, and after a period of time Δt, comparing the image at time t with the image at time t+Δt, thereby identifying static or dynamic images in the pixel. Then, there is recording a gain of every pixel by a brightness regulator using an image gains memory buffer zone, the gain being regulated according to detection results of the static image detector. Finally, there is improving gray level performance of output images by a gray level promoter and brightness converter. Thus, method actively detects static pixels and reduces brightness in the static region for minimized image sticking.

摘要： A method for adjusting a degree of saturation of a target pixel is provided. In a first color space, the target pixel is represented by a brightness factor and a set of color factors. Based on the set of color factors, the method first generates an original saturation and a hue factor. Then, selectively according to the brightness factor, the hue factor, and the original saturation, an adjusting gain is generated. The method, according to this invention, multiplies the original saturation by the adjusting gain to generate a new saturation for the target pixel.
