摘要： Brightness correction apparatus and method for a plasma display, where the non-linear relationship between the gray scale and the brightness of the plasma display is considered. The brightness error is measured to build up a brightness error table. When the gray scale data of the currently displaying pixel is received, the brightness error diffusion method is applied. The weighted display brightness error of the neighboring pixel is incorporated for calculation to obtain an optimal display result. When the modified output gray scale data is derived by calculation, the brightness error table is looked up, and the display brightness error of the currently displaying pixel is thus saved to provide modification calculation for other pixels.

摘要： A method for adjusting a target gray level of a target pixel based on a spatial mask is provided. The target pixel is surrounded with N adjacent pixels; each of the N adjacent pixels respectively has an adjacent gray level. The method first multiplies the target gray level with a sharpness index to generate an amplified target gray level and respectively multiplies each of the adjacent gray level with an adjacent index to generate N modified adjacent gray levels. Then, the amplified target gray level and the N modified adjacent gray levels are added up to generate a first gray level sum. The method multiplies the first gray level sum with a multiplying parameter to generate a second gray level sum. At last, the method divides the second gray level sum by a dividing parameter to generate an adjusted gray level for the target pixel.

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.
