1) DSS CONTROL ( DIGITAL SLOW SHUTTER )
The Levels of Fields are ranged from 2X ~32X.
User can set slow shutter limit from 2x ~ 32x and select COLOR or B/W image when slow
shutter is operation by setting SS PROTERTY.
When DSS is set OFF, it operates with AGC in low light condition to keep the color image.
When DSS is set “ON” ,the camera will merge into the slow shutter mode in low light
condition.
The default SLOW SHUTTER setting is OFF.
2) WHITE BALANCE SPEED
①
ATW Slew
ATW slew Controls the rate of change when transitioning from one color thmperature to
another,
An example of this would be panning the camera from an indoor fluorescent scene of
4000K out a window to a daylight scene of 6500K.
The slew property tells the camera how fast to make the adjustment from 4000K to 6500K.
The property itself is a value from 1 to 100, with I being the fastest slew and 100 being the
slowest.
②
HYST
White balance auto hysteresis sets a threshold around the current color temperature
reading.
The measured color temperature must exceed this threshold before the current white
balance setting will change.
The purpose of hysteresis is to ensure that the camera does not dither back and forth
between two different modes of operation, when the meter reading are near a boundary
between the two mode.
However making the hysteresis threshold too high will make the camera appear
unresponsive.
3) EXPOSURE & Dynamic range speed
①
Filter
The first step in processing camera response and transition rates is to apply a low-pass
filter to incoming exposure readings. This filter can be set to prevent the camera from
responding to very fast transient changes in meter readings.
The typical use of the filter is to keep the camera output stable when monitoring a high
activity scene.
