When you select one from various exposure modes, some of the following setting items that are required for
the selected mode will appear.
GAIN: Select the gain from the following:
0dB, 3dB, 6dB, 9dB, 12dB, 15dB, 18dB, 21dB, 24dB, 27dB, 30dB, 33dB, 36dB
GAIN LIMIT:
The gain limit can be set at Full Auto, Iris Priority, Shutter Priority mode. Use this setting when you want to
obtain image in which signal-to-noise ratio is particularly important.
Select the gain limit from the following: 9dB, 12dB, 15dB, 18dB, 21dB, 24dB, 27dB, 30dB, 33dB, 36dB
GAIN POINT:
Set the Gain Point in the middle between 0dB and gain limit. The shutter speed can be changed from the point
when the set gain value is reached. When you want to obtain the motion-priority image, use this setting.
HIGH SENSITIVITY:
In this mode, the maximum gain increases, enabling to obtain a brighter output even in a darker environment.
However, if the gain reaches high level, the image will have a large amount of noise.
IRIS: Select the iris from the following: F11, F10, F9.6, F8.7, F8.0, F7.3, F6.8, F6.2, F5.6, F5.2, F4.8, F4.4,
F4.0, F3.7, F3.4, F3.1, F2.8
SLOW SHUTTER:
When set to "On," the slow shutter functions automatically when the light darkens. This setting is available
only when the Exposure mode is set to "Full Auto." The initial setting is "Slow Shutter Off."
S. SHUTTER LIMIT:
When the subject becomes dark, the shutter speed becomes slow and the gain is increased. This is a function
to put a limit on the shutter speed. It prevents the camera shake when you shoot a moving subject in a dark
place.
Select the S. Shutter limit from the following: 1/30, 1/20, 1/15, 1/10, 1/8, 1/6, 1/4, 1/3, 1/2, 2/3, 1/1.
AE SPEED:
The AE Speed function allows you to reduce the exposure response speed. Usually the camera is set up so
that the optimum exposure can be obtained automatically within about 1 second. However, using the slow AE
Speed function allows you to lengthen the auto exposure response speed from the initial setup speed.
Maximum SPEED (Maximum Shutter Limit)
The brighter the object is, the shutter speed will increase. This is the function to set the upper limitation on the
shutter speed. This will help to make images smooth with less inconsistent motions when you shoot bright
objects.
Minimum SPEED (Minimum Shutter Limit)
When the subject becomes dark, the shutter speed becomes slow and the gain is increased. This is a function
to put a limit on the shutter speed. It prevents the camera shake when you shoot a moving subject in a dark
place.
BACKLIGHT:
When the background of the subject is too bright, or when the subject is too dark due to shooting in the AE
mode, back light compensation will make the subject appear clearer.
SPOT LIGHT:
This menu allows you to enable/disable spotlight compensation by adjusting the exposure darker when a part
of the object is bright, such as a person's face in spotlight. You can choose either ON or OFF. This setting is
enabled when MODE is FULL AUTO, SHUTTER PRI, IRIS PRI, or GAIN PRI. SPOT LIGHT becomes
disabled when BACK LIGHT is ON.
EX-COMP: (Exposure Compensation)
When MODE is set to one of FULL AUTO, IRIS PRI, SHUTTER PRI or GAIN PRI, set this item to ON to
