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.
