Video Signal Auto-White Processing IC
LA7668N
Overview
The LA7668N is a low-cost video signal auto-white
processing IC that provides brightness adapted
compression and expansion functions. Furthermore, the
LA7668N incorporates on-chip a Sanyo developed
vertical line saturation suppression function for image
quality enhancement.
