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.

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： The invention discloses a hue dividing and judging device including a memory unit, a calculation module, and a judgment module. The memory unit is used for storing a look-up table, and the look-up table records N boundaries, wherein the N boundaries includes j+1 operative boundaries for defining j color areas. The calculation module is used for calculating the hue of each pixel of an input image. According to the look-up table, the judgment module is used for judging where the hue of each pixel falls within two of the operative boundaries, so as to judge that the hue of the pixel of the input image falls into which one of the color areas. Accordingly, if there are more operative boundaries recorded in the look-up table, the hue will be divided into more color areas, and the user will have more choices for adjusting the color of the input image.
