(4) High performance, High Sensitivity and Low Vertical Smear
The latest interline transfer CCD with on-chip-micro lens technology provides
a wider spectral response from the visible to invisible near infra-red, for high
quality, effective picture reproduction from brightly to dimly lit areas. And the
improved DSP, Digital Signal Processor, permits good signal-to-noise ratio of
52dB with good performance of -126 dB vertical pixel overload protection known
as vertical smear that occurs with intense strong light sources.
(5) Intelligent Back Light Compensation
Well-designed BLC, back light compensation, facility is provided which can
assign a compensation area for back light compensation to have an optimum
balanced clear picture reproduction, by the rear control panel switches, or
remotely via Link.
(6) Two-way automatic iris control
This function is available to switch between Video type iris lens and DC type
iris lens. In other words, almost all types of automatic iris CCTV lenses can be
used.
(7) Automatic white balance
Thanks to the automatic tracking white balance control (ATW), the white balance
adjusts itself no matter how great the subject's color temperature fluctuates.
The ICD-879 provides various useful white balancing functions to meet the
most testing of users requirements resulting in full time automatic color balance,
extended spectrum range balancing (ATW-1 and ATW-2), normal one-touch
white balance and manual balancing by individual R and B gain controls.
(8) AES, Automatic Electronic Shutter
A smooth control to compensate sensitivity variation with an electronically
controlled Auto-shutter, that gives a control range of 1600 to 1 range is employed
to assure a constant optimum picture reproduction.
This AES function gives an acceptable reproduction capability, equivalent to
F1.4 to F50 Iris Control range, even with fixed Iris lenses.
