1. Exposure Setup menu (page 1)
Gain [AGC/step/ISO]
Adjusts video gain.
AGC Automatic gain control. Automatically adjusts the gain
of the video signal in accordance with the brightness
of the subject. This function is useful for shooting
subjects under changing lighting conditions.
step Sets the video gain to manual control. Use this
function for shooting in extremely dark places where
even fully opening the lens iris still does not produce
an acceptably bright image. The gain level can be set
in the range of 0 to 18 dB in units of 1 dB.
ISO Sets the video gain to the desired level in the ISO
sensitivity display (frame mode). The gain level can
be set to 400, 800, or 1600. In the field mode, the real
value is twice the displayed value. When used with a
still-image camera (for example, a single-lens reflex
camera), this item serves as a reference for
approximate exposure settings. For greater accuracy,
check the exposure level with an exposure meter as
this value may change depending on the lighting
conditions.
Shutter [off/long exp/step/c.scan/CCD-IRIS]
The electronic shutter allows for blur-free images of fast-
moving subjects and, if used in combination with the frame
memory, produces good still images of subjects shot in
poor lighting conditions.
Note
If you are using the Shutter, be sure to set "Flash" to "off."
off Deactivates the electronic shutter.
long exp Sets the shutter speed in units of 1 frame.
Range: Field mode: 1 – 255 FRM (frames)
Frame mode: 2 – 256 FRM (frames)
For more details on field and frame modes, see page 93.
For example, if the value is set to 050 frames (about
1.7 seconds in the NTSC format), the total amount of
video signals accumulated during this set time is
output in the form of one complete field (or one still
frame) at intervals of about 1.7 seconds. These
pictures, which contain 50 frames of video
information, are much brighter than normal one-frame
images. This mode of setting the shutter speed is very
useful for shooting a poorly illuminated subject in a
dark place. The WEN (timing) video signals can be
output from the RGB/SYNC
back of the unit. This function synchronizes an
external frame memory with the timing pulse to allow
for image processing or image analysis.
