A color transient improvement unit and method for improving color transients to remove blurring along the edges of color transitions is presented. A transient characterization unit calculates various transient characterization values for a color transient detection window surrounding a current pixel. A transient threshold unit analyzes the transient characterization values to determine whether the color transient detection window contains a color transition. If a color transition exists, a transient correction unit generates an improved U chrominance value and an improved V chrominance value for the current pixel.
