Zoom
The EVI-D100/P uses an 10
× optical zoom lens. And
its digital zoom function allows you to zoom up to
40
×.
• Optical 10
×, f = 3.1 to 31 mm (F 1.8 to F 2.9)
The horizontal angle of view is approximately 65
degrees (wide end) to 6.6 degrees (tele end).
Digital zoom increases the picture element size and
reduces the resolution.
Extended control of zoom:
• Direct zoom position
• Zoom speed selection (8 speeds)
• Digital zoom can be switched ON/OFF
Focus
The minimum focus distance is 100 mm at the optical
wide end and 600 mm at the optical tele end, and is
independent of the digital zoom.
The AutoFocus (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.
Note
AVOID 24-hour continuous use of the autofocus. This
may cause lens malfunction.
All of these settings are performed via RS-232C
control. If the RS-232C is not used, white balance, iris
and gain adjustments will be carried out automatically,
and the shutter speed will be fixed at 1/60 seconds for
the EVI-D100 and 1/50 seconds for the EVI-D100P.
Extended control of focus:
• Direct focus position
• Minimum focus distance limitation
• Manual focus speed selection (8 speeds)
• AutoFocus can be set to High or Low mode
• One Push AF can be achieved in manual focus mode
• HIGH AF
High reaction speed of the AF. Use this mode when
shooting fast moving objects. Recommended as the
optimum mode for normal NON-CONTINUOUS
use.
• LOW AF
Better focus stability. In low luminance conditions,
the AF discontinues operation even when brightness
changes, enabling stable images.
White Balance
• Auto
Auto Tracing White Balance with limitations on R
and B gain (3000 to 7500 K), to avoid fixing single
color scenes as ‘white’
• ATW
Auto Tracing White balance (2000 to 10000 K)
• Indoor
3200 K
• Outdoor
5800 K
• One Push WB
One Push White Balance 1)
• Manual WB
Manual control of R and B gain, 256 steps each
