4 Auto 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.

FIX—fixed white balance

Point the camera at a white object and bring it into focus. Move dip switch to

the FIX mode.

5 AE 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 1/50(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 is fixed 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.

Auto 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
