Windows weighing setting
The weighing of windows 0 to 3 can be individually set within a range
from 0 to 15. Weighing of central window is fixed at maximum value
15. Default values of other windows are listed as follow;
WNDW 0 WEIGHT
1
WNDW 1 WEIGHT
1
WNDW 2 WEIGHT
3
WNDW 3 WEIGHT
3
The combination of these two types of BLC delivers this camera better
picture even under severe environment. However, the BLC may be
insufficient under extremely strong back light condition.
7.1.2 Av : Pk setting (for all AE modes)
This option determines the method of photometric measurement,
while using DC servo Auto Iris lens. Av value means that the
electronic convergence is automatically adjusted according to the
average video signal level of the object. Pk value means that the
electronic convergence is automatically adjusted according to the
peak video signal level of the object.
The Av : Pk ratio represents the portion of two different methods.
Total 12 combinations (0:12, 1:11, 2:10, 3:9, 4:8, 5:7, 6:6, 7:5, 8:4,
9:3, 10:2, 11:1, 12:0) can be set. The default setting is 8:4.
7.1.3 AGCMAX setting (for all AE modes)
This option determines the maximum gain of AGC level. Range of
AGCMAX setting is from 0 to 36 dB. The default setting is 30 dB.
Under the AES mode, AGC is normally at minimum level (0 dB) and
camera exposure is virtually controlled by electronic iris of the
camera. If the exposure is still insufficient even the shutter speed has
been switched 1/50 (1/60) sec., then the AGC will operate to optimize
the camera exposure. On the contrary, AGC will reduce the gain first
if camera is over exposure. However, if the exposure is still excessive
even the AGC is reduced to minimum, then electronic iris will shorten
the exposure time to optimize the exposure.
