摘要： An image processing device and a method thereof are provided. In the image processing method, an adjusting value is computed according to a pixel of a current image and a plurality of reference pixels nearby. In addition, a weighted coefficient is computed according to a gray-scale difference between the pixel of the current image and a pixel of a previous image. Further, a weighted adjusting value is computed according to the adjusting value and the weighted coefficient. Besides, the pixel of the current image is adjusted according to the weighted adjusting value to generate a pixel of an output image. Thereby, the current image is adjusted adaptively to increase the quality of the output image.

摘要： A driving circuit and a gray insertion method of a liquid crystal display (LCD) are described. In the gray insertion method, whether a dynamic frame or a static frame display by the LCD is determined. When the LCD displays the dynamic frame, a gray insertion level of a frame of the display and a duty cycle of a pulse width module (PWM) signal are increased synchronously, wherein the PWM signal drives a back light module of the display. When the LCD displays the static frame, the gray insertion level of a frame of the display and the duty cycle of the PWM signal are decreased synchronously. As a result, a motion blur on LCD is reduced and luminance of a display frame is maintained.
