Features
Single chip LSI camera signal processor
Hitachi's leading edge processing technology
(0.18 um, internal core 1.8V drive, and 3 million
gates) is contained on a single newly developed
ultra LSI chip.
The system is compact and
consumes very little power. Also, the 12-bit A/D
converter and 14-bit internal processor provide
high signal to noise ratio and wide dynamic
range.
C moot
The camera uses a C mount lens, which is the de
facto standard in the industry
Note : Some lenses cannot be used.
before use. See page 7 when using lens.
High quality picture
Three 410,000 pixel (470,000 PAL) CCDs with
high sensitivity microlenses are mated to prism
optics using high precision matching technology.
Accelerated digital luminance signal processing
is used to deliver a horizontal resolution of 800
TV lines with HV-D27A and 750 TV lines with
HV-D37A (luminance channel).
A new digital noise reduction system provides 62
2
dB (60dB PAL) with HV-D27A and 60dB (58dB
PAL) with HV-D37A signal to noise ratio. Clear
low noise images are obtained even in high gain
mode.
Auto shading compensation (ASC)
Color shading incurred when using a C mount
lens is automatically compensated (attenuated).
Two modes of shading are provided and can be
selected according to the cameras application, a
vertical color shading mode or a two-dimensional
luminance-shading mode.
