    摘要: Reducing fast motion artifacts in an LCD panel by receiving a video stream at a first frame rate which is then downsampled to a second frame rate. The downsampled video stream is then upsampled to a third frame rate and a voltage is applied to a pixel element such that the pixel element transitions from a first pixel value to a predetermined second pixel value within a period of time consistent with the third frame rate.

    摘要: In a method and apparatus for operating a super-heterodyne receiver, a tuning circuit has a local oscillator for frequency shifting a desired channel to a selected frequency and a controller for controlling the local oscillator. The controller determines for each of a number of identified channels, whether an image signal is present at frequencies in the spectrum that when tuned to a first selected frequency interfere, and is operable to select a modified selected frequency at which interference between the image signal and the identified channel is reduced.
