Basic Functions
AE – Shutter Priority
The shutter speed can be set freely by the user to a
total of 22 steps – 16 high speeds and 6 low speeds.
When the slow shutter is set, the speed can be
1
/30,
1
/15,
1
/8, or
1
/4 s. The picture output is read at a normal
rate from the memory. The memory is updated at a low
rate from the CCD. AF capability is low.
In high speed mode, the shutter speed can be set up to
1
/10,000 s. The iris and gain are set automatically,
according to the brightness of the subject.
a) For AE-Manual only.
Note
When the shutter speed 1/1 s or 1/2 s is used, Auto
Focus and White Balance may not function fully.
AE – Iris Priority
The iris can be set freely by the user to 18 steps
between F1.4 and Close.
The gain and shutter speed are set automatically
according to the brightness of the subject.

AE – Manual
The shutter speed (22 steps), iris (18 steps) and gain
(16 steps) can be set freely by the user.
AE – Bright
The bright control function adjusts both the gain and
iris using an internal algorithm according to a
brightness level freely set by the user. Exposure is
controlled by gain when dark and by iris when bright.
As both gain and iris are fixed, this mode is used when
exposing at a fixed camera sensitivity. When switching
from Full Auto or Shutter Priority Mode to Bright
Mode, the current status will be retained for a short
period of time.
Only when the AE mode is set to “Full Auto” or
“Shutter Priority,” the user can switch it to “Bright.”
