AE – Manual
The shutter speed (22 steps), iris (14 steps) and gain
(15 steps) can be set freely by the user.
Spot Exposure Mode
In Full Auto AE, the level for the entire screen is
computed and the optimum Auto Iris and Gain levels
are determined. In Spot AE, a particular section of the
subject can be designated, and then that portion of the
image can be weighted and a value computed so that
Iris and Gain can be optimized to obtain an image.
For example, in an image with a lot of movement and
with varying levels of brightness, portions without
much change can be designated as such a “spot,” and
changes to the screen can be minimized in that area.
As shown in the diagram below, a range of 15 blocks
vertically and 17 blocks horizontally can be designated.
In the case where the center is designated (shown in
black), the level is computed along with a weighted
value for the surrounding block (shaded), including the
specified portions; and then the Gain and Iris are set.
The value of the designated portions and the
surrounding areas should be calculated as 100%, the
rest should be set to 20%. The range of the Spot AE
frame is fixed to 5 blocks vertically and 4 blocks
horizontally.

Wide-D/HLC/Backlight Compensation/Spot Exposure Mode do
not work at the same time.
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 adjusted
according to subject brightness. The picture output is
read at a normal rate from the memory. The memory is
updated at a low rate from the CMOS. AF following
capability is lowered and also the number of frame to
be displayed is decreased. In high speed mode, the
shutter speed can be set up to 1/10,000s. The iris and
gain are set automatically, according to the brightness
of the subject.

AE – Iris Priority
The iris can be set freely by the user to 14 steps
between F1.6 and Close.
The gain and shutter speed are set automatically,
according to the brightness of the subject.
