Abstract
Official abstract text for this publication.
Disclosed are an image quality improvement device and method. The image quality improvement device includes a filter which separates an input video signal into a luminance signal and a chrominance signal, and a noise reduction unit which detects a motion in the input video signal by using the luminance signal separated by the filter, and thereby performing different filtering operations according to the existence of the motion.
First claim
Opening claim text (preview).
What is claimed is: 1. An image improvement device comprising: a filter which separates an input video signal into a luminance signal and a chrominance signal; and a noise reduction unit which detects a motion in the input video signal by using the luminance signal separated by the filter and performs a two-dimensional filtering operation or a three-dimensional filtering operation according to an existence of the motion, wherein the noise reduction unit decides that the motion…
