Notes
z
When the remote control unit (AJ-RC10G: optional) or the
extension control unit (AG-EC4G: optional) is connected,
and I.OVR and C TEMP are assigned to the USER button on
the AJ-RC10G or AG-EC4G, operation of this unit’s JOG dial
button is disabled.
z
The functions below also go OFF when the power of this unit
is turned OFF.
I.OVR/S.BLK/B GAMMA/Y GET/DRS/ASSIST/C.TEMP/ATW/
ATW LOCK/D.ZOOM/S.GAIN/DS.GAIN
However for C.TEMP, variable color temperature will be
retained.
AJ-HPX3100 allows three other modes to be used in
addition to the L/M/H standard gain settings: the analog
gain-up S.GAIN (super gain) mode to achieve a gain of 30
dB or more, the cumulative gain-up DS.GAIN (digital super
gain) mode which uses progressive drive.
To select these functions, perform menu operations to select
the S.GAIN item and DS.GAIN item, and preset the gain to
be used for each item. These menu items are found in the
<USER SW GAIN> screen on the CAM OPERATION page.
For instance, if the S.GAIN and DS.GAIN functions have
been allocated to the USER MAIN button, USER1 button or
USER2 button, the gain can be increased by using these
buttons in combination with the USER buttons.
1) To increase the gain without increasing noise:
The DS.GAIN function is used.
2) To increase the normal analog gain:
(noise is increased)
Use the S.GAIN feature alone.
Note
Note that the accuracy of AUTO IRIS, White Balance, and
Black Balance may be influenced by an increase in noise.
3) To achieve ultra-high sensitivity:
Use the S.GAIN function and DS.GAIN function in
combination. However, exercise care during operation
since image lag will become more conspicuous with
moving subjects the more the gain is increased by using
the DS.GAIN function.
When shooting moving subjects, keep the gain increase
with the DS.GAIN function to under 12 dB
