HITACHI HV-D30
MANUFACTURER: HITACHI
Digital Signal Processor:
A 3rd generation Digital Signal Processor (DSP) chip utilizing
Hitachis most recent processing technology (0.18΅m, internal
core, 1.8V drive, and 3 million gates) is contained on a single
newly developed ultra LSI (large scale integration) chip. The
new DSP enables the camera to achieve its small size, low
power consumption, and high stability.
Performance in a cube:
The camera is built into a compact cube with a short depth
dimension for easy incorporation into systems where space is
critical. The multi-functional design is conducive to a wide
range of industrial, medical, and other general purpose imaging
applications.
High picture quality:
High Sensitivity and High Resolution are achieved through the
use of three 1/3 inch CCDs, each with 410,000 picture elements
(470,000 PAL). Together with the 12-bit analog to digital (A/D)
converter and 14-bit accelerated DSP a horizontal resolution of
800TV lines and a high signal to noise ratio (S/N) of 64 dB (62
dB PAL) is obtained with the use of dynamic noise reduction
(DNR). Clear high quality low noise images are now possible
even in a high gain mode.
Adjustable Flange back:
A built-in flange back adjustment allows the cameras optical
focus to be optimized with the selected optical system.
Auto Shading Compensation (ASC):
The ASC function can automatically compensate for color shading
errors caused by interaction between the lens and prism
assembly in C-Mount optical systems. Two modes of shading
are provided and can be selected according to the cameras
application, a color shading mode or a two-dimensional luminance-
shading mode.
FEATURES:
Four scene files are provided for the setup, storage and recall
of all camera functions.
The camera configuration can be easily changed through the
selection of a scene file.
A six-vector color corrector allows independent adjustment of
the hue and saturation of the primary and secondary colors so
that optimum color fidelity can be maintained.
A versatile color detail adjustment circuit enables the selection
and independent adjustment of detail in two separate colors.
This function can be used as a flesh tone detail circuit for
smoothing human complexion, or for enhancing a color contour
for increased visibility.
Dynamic Chroma Compensation is provided to maintain proper
color saturation in scenes with high luminous levels. Dynamic
range is expanded allowing high quality reproduction of outdoor
and other difficult scenes.
Intelligent Auto Level Control (ALC) can be selected to allow
unattended operation over a wide range of light levels. Digital
light metering, CPU controlled automatic gain control (AGC),
lens iris, and an auto electronic shutter (AES) operate under
continuous control to compensate for varying light levels. Auto
Tracking White Balance (ATW) can also be selected to maintain
proper color temperature with changing light levels. Note:
AES functions continuously only with a manual override lens.
Flare Compensation can be adjusted to compensate for color
changes in dark areas, improving color fidelity, when a zoom
lens is used on the camera.
Picture polarity can be selected as normal (positive) or negative,
to suit the imaging requirements.
A full complement of video outputs is provided on the camera.
Outputs include composite, Y/C, RGB, or Y/ R-Y/ B-Y.
Simultaneous output of composite, Y/C and an additional component
signal is possible, utilizing two separate output connectors.
The camera can be synchronized with external devices using
the genlock input or by use of external HD and VD signals.
Composite sync, HD and VD signals can be output for use with
other equipment.
An External Trigger Signal can be used to provide the capture
of an image. Several trigger modes are available to suit the
intended application. A long term integration mode of up to 8
seconds can be used to capture images at extremely low light
levels.
An RS-232C port is provided for bi-directional communications
with an external device, allowing complete control, setup and
operation of all camera functions.
