Patent ID: 7675483

Claim:
A dynamic false contour reducing circuit comprising: a first coding part which receives an input signal and generates a first coding signal by performing a first coding process on said input signal; a first false contour detecting part which detects a first false contour intensity on a pixel of interest produced when an image is displayed on said pixel of interest based on said first coding signal; a second coding part which receives the input signal and generates a second coding signal by performing a second coding process on said input signal; a second false contour detecting part which detects a second false contour intensity on the pixel of interest produced when an image is displayed on said pixel of interest based on said second coding signal; a selecting part which compares said first and second false contour intensities and selects one of said first and second coding signals which has a lower intensity between said first and second false contour intensities; and a display control part which controls a display part so that an image is displayed based on the said selected one of said first and second coding signals.
