Abstract
An image processing apparatus for sharpening edge boundaries of an image is provided. The image processing apparatus includes a transient improvement (TI) circuit and a color protection circuit. The TI circuit receives multiple original pixel data and performs a TI process on an original target pixel data from the original pixel data to output first and second TI chroma signals corresponding to the original pixel data. The color protection circuit respectively compares the first and second TI chroma signals with first and second original chroma signals of the original pixel data to correspondingly generate a weighting value, and outputs first and second adjusted chroma signals according to the weighting value, the first and second original chroma signals, and the first and second TI chroma signals.
