Abstract
A digital signal processing system and method applied for chroma transition, wherein the method has the acts of: performing a difference process on an original chroma signal C to obtain a first difference signal C'; calculating an absolute value |C′| of the first difference signal C′; performing a difference process on the absolute value |C′| to obtain a second difference signal Ca′; determining whether the second difference signal Ca′ is a positive signal or a negative signal; wherein based on a determined result, an optimized chroma signal is generated by either mixing the original input chroma signal C with a k-delayed chroma signal, or mixing the k-delayed chroma signal C[n−k] with a 2k-delayed chroma signal C[n−2k], where k is a constant.
