Abstract:
1. A method for separating a video signal into a luminance signal and a chrominance signal, the video signal being sampled from a composite color TV signal according to a sampling frequency, the method comprising the following steps: (a) generating a target video signal and a plurality of reference video signals by delaying the video signal; (b) generating an HCS according to the target video signal; (c) generating an SLFD according to the target video signal and the plurality of reference video signals; (d)generating a UDFD and a plurality of VRVSs according to the target video signal and the plurality of reference video signals; (e) generating a VCS according to the UDFD and the plurality of VRVSs; (f) generating the chrominance signal of the video signal by determining the HCS, the VCS, and the SLFD; and (g) generating the luminance signal of the video signal according to the chrominance signal of the video signal and the plurality of reference video signals.
