Overview of Functions
Zoom
The SRG camera employs a 30× optical zoom lens
combined with a digital zoom function; this camera
allows you to zoom up to 360×.
• Optical 30×, f = 4.3 mm to 129 mm
(F 1.6 to F 4.7)
Digital Zoom enlarges the center of the subject by
expanding each image in both the vertical and
horizontal directions. When the digital zoom is used,
the resolution deteriorates.
You can activate the zoom in the following modes, all
of which can be set using VISCA command.
Standard Mode
Variable Mode
There are eight levels of zoom speed.
In these standard and variable modes, it is necessary to send
Stop Command to stop the zoom operation.
Direct Mode
Setting the zoom position enables quick
movement to the designated position.
Digital Zoom ON/OFF
Basic Functions
Focus
Focus has the following modes, all of which can be set
using VISCA Commands.
• Auto Focus Mode
The Auto Focus (AF) function automatically adjusts
the focus position to maximise the high frequency
content of the picture in a center measurement area,
taking into consideration the high luminance and
strong contrast components.
The minimum focus distance is 10 mm at the optical
wide end and 1200 mm at the optical tele end.
- Normal AF Mode
This is the normal mode for AF operations.
- Interval AF Mode
The mode used for AF movements carried out at
particular intervals. The time intervals for AF
movements and for the timing of the stops can be
set in one-second increments using the Set Time
Command. The initial value for both is set to five
seconds.
- Zoom Trigger Mode
When the zoom is changed, the AF mode activates
for the pre-set time. Then, it stops. The initial
value is set to 5 seconds.
AF sensitivity can be set to either Normal or Low.
- Normal
Reaches the highest focus speed quickly. Use this
when shooting a subject that moves frequently.
Usually, this is the most appropriate mode.
- Low
Improves the stability of the focus. When the
lighting level is low, the AF function does not take
effect, even though the brightness varies,
contributing to a stable image.
