VTC-C574
1/3" Hi-Res Color CCD Camera
INSTRUCTION MANUAL
1General
This color video camera employs 1/3 inch SONY charge coupled device solid-state
imaging device, and equipped with a newly developed DSP (Digital Signal
Processor) for video signal processing, to provide high color fidelity, sharp, stable
picture.
2Features
1. 480 lines of horizontal resolution and high quality video utilizing digital processing
2. 0.5lux Minimum illumination and signal-to-noise ratio of 48 dB is achieved by
employing a highly sensitive image sensor with micro lenses and low noise circuit
design.
3. High quality picture –A digital signal processor performs digital horizontal and
vertical aperture enhancement to produce high quality picture.
4. A newly developed intelligent wide range Auto Tracing White Balance (ATW) that
automatically adjusts the tone according to the color temperature of the light
source.
5. Smart digital control Auto BLC, the combination of Histogram equalizer and
Central windows weighting BLC functions ensure for use against any unusual
lighting conditions.
6. Advanced Auto Exposure System for both fixed iris and auto iris lenses controls
the amount of light to ensure optimum video signal.
7. AC 24V model built-in Line-lock sync.
To prevent electric shock, do not remove screws or covers.
There are no user serviceable parts inside.
Contact a qualified service person if necessary.
Warning:
To prevent fire or electric shock hazard, do not expose
the appliance to rain or moisture

4Auto Tracing White Balance
4.1 ATW—Auto tracking white balance
This camera is equipped with an digital auto tracing white balance function,
This ensures white balance control based on the absolute color temperature of
the object and adjusts automatically.
Auto color temperature tracing white balance is a feedback system, that
aligns the white balance by detecting the R-Y and B-Y signal. After performing
white detection, the convergence shift processing is judged and accurately
operated by internal micro-controller.
The operating color temp. range is from 3200°K to 7500°K approximately.
4.2 FIX—fixed white balance
Point the camera at a white object and bring it into focus. Move dip switch to
the FIX mode.
5AE Mode
5.1 AES (CCD IRIS) mode
AES mode is performed by the CCD iris and AGC, the range of the electronic
shutter is from 1/60 to 1/100,00 second; the AGC range is from 0 to 36 dB.
5.2 Auto Iris DD Mode
In this mode, the shutter speed isfixed at 1/60 sec. NTSC. Auto exposure
operation is performed by AGC through the microcontroller and mechanical iris
of external lens. The back light compensation amount is calculated by internal
microcontroller, then output and supplied to the governor inside the auto iris
lens.
6Auto Back-light Compensation
This auto BLC function consists of two methods of Backlight compensation; one is
Central Windows weighted average BLC, the other is Histogram calculating BLC.
Microprocessor (dip switch ON position)
The combination of two types of backlight compensation makes it easier to arrange
backlight operation to match the imaging conditions and installation location.
