摘要： A method for adjusting an image on the basis of characteristics of a display system is provided. The image includes M horizontal lines. Each of the M horizontal lines respectively includes N pixels. Each pixel has an original gray level. A look-up table previously stores a plurality of conversion coefficients related to the characteristics of the display system. The method first calculates an ith loading according to the N original gray levels of the N pixels in the ith horizontal line. Based on the ith loading, an ith conversion coefficient corresponding to the ith loading is selected from the plurality of conversion coefficients in the look-up table. The method respectively multiplies the N original gray levels of the N pixels in the ith horizontal line by the ith conversion coefficient to generate N new gray levels for the N pixels in the ith horizontal line, whereby the image is adjusted.

摘要： The present invention provides a method to automatically regulate brightness of liquid crystal displays (LCDs), which resolves the overload and easy fatigue of human eyes and poor image contrast due to high brightness of the conventional LCD. The present invention includes use of four parts, including an image brightness regulating unit, an image brightness ratio computation and output controlling unit, an ambient light detection and brightness adaptation regulating unit and an image gray level expanding unit. The image signals of an LCD are processed in such a manner to enable automatic control of optical flux of LCD TV by regulating the gray level of output images. Also, optical flux of LCD TV can be automatically controlled with the change of images and ambient light, thus alleviating overburdening of human eyes and improving the contrast and comfort of images for a better visual effect.

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.
