Abstract:
1. A video signal processor for transforming an input video signal of a first frame frequency into an output video signal of a second frame frequency, the output video signal being displayed on a display unit having a clock frequency equal to the second frame frequency, the video signal processor comprising: a delay unit for generating a delayed input video signal from the input video signal; an interpolation unit for generating an interpolated frame signal from the input video signal; and a switching unit for generating a first output signal corresponding to a first display area of the display unit and for generating a second output signal corresponding to a second display area of the display unit other than the first display area, the first output signal being generated from the input video signal or from the input video signal and the interpolated frame signal, and the second output signal being generated from the delayed video signal or from the delayed video signal and the interpolated frame signal; wherein the switching unit integrates the first output signal and the second output signal into the output video signal.
