Abstract: The paper proposes an independent color adjustment circuit based on hue and saturation components. The circuit is capable of selective color adjustment during video post-processing and avoids any influence on other parts. It is characterized of accurate color region selection and natural transition.. Being Manufactured in TSMC 0.18 μm process, the circuit works at 150 MHz and uses CORDIC algorithm with good real-time processing capability.

Key words: hue, saturation, independent color adjustment, video post-processing, CORDIC
