Color-Difference Signal
Correction IC for Color TVs
Overview
The LA7698 performs flesh-tone correction and green
enhancement for color TV color-difference signals, and
includes a color limiter function that prevents color saturation
on the screen and color noise reduction (CNR) circuitry that
eliminates color- difference output noise.
Functions and Features
Flesh-tone correction, green enhancement, color limiter and
CNR.
The center axis of flesh-tone correction can be adjusted.
Because green detection is performed through R-Y and B-Y
detection, OSD green is not enhanced.
The demo mode switch makes it possible to turn flesh-tone
correction and green enhancement on and off for the left and
right sides of the screen independently.
The effectiveness of CNR can be adjusted through an
external capacitor.
