General Description
The HT82V863R is a single chip digital image
processor for Ye, Cy, Mg and G colour CCD video
camera systems. It receives CFA patterns from colour
CCDs and generates NTSC/PAL CVBS signals
using internal video encoders and the 10-bit DAC.
In addition, it also provides an AE/AWB algorithm,
timing generation module together with other
circuitry.
The device contains a microcontroller in which an
OTP ROM is integrated internally to implement
the basic camera functions such as the AE/AWB
algorithm. The video camera system consists of
a CDS/AGC/ADC IC (HT82V842A), DSP IC
(HT82V863R), Vertical Driver IC (HT82V805) and
CCD sensors. It also provides a proprietary function
to eliminate so called “line crawl” and automatic
CCD defect compensation function to correct up to 30
bad pixels and 4 consequential bad pixels.
