CXD3142R

Signal Processor LSI for Single-Chip CCD Color Camera

Description

The CXD3142R is a signal processor LSI for Ye,

Cy, Mg and G single-chip CCD color cameras. In

addition to basic camera signal processing functions,

it includes an AE/AWB detection circuit, a sync signal

generation circuit and an external sync circuit, etc.

This chip also has a built-in microcontroller to realize

basic camera functions such as AE/AWB without an

external microcomputer.
