8-4-3. GAIN
(1) Select GAIN on the main menu
screen. Press the E button, and the
screen at right shows up.
(2) GAIN
With the L and R buttons, the gain
control modes can be selected.
① AGC
This mode is initially set to
automatically optimize the sensitivity and the noise levels.
② HYP-AGC
This mode is higher in sensitivity than AGC. But images may look rugged at
higher sensitivities.
③ LOW
This fixed-gain mode keeps the sensitivity low for brighter spots.
④ MID
This fixed-gain mode keeps the sensitivity middle between HIGH and LOW.
⑤ HIGH
The fixed-gain mode keeps the sensitivity high for darker spots.
(3) SENS UP
The electronic sensitivity up modes can be selected with the L and R buttons.
At all the positions but OFF, the automatic gain control function turns on itself.
The HYP-AGC mode can also be switched on.
① OFF (initial setting)
② S/N
The signal-to-noise ratio priority mode is used in shooting subjects that vary
in brightness and move slightly.
③ STD
The standard mode is used in shooting subjects in brightness-changing spots
to suppress both blurry images and rugged looks.
④ MOVE
The motion priority mode is used in shooting subjects that vary in brightness
and move greatly like on the street and in parking lots.
* Note: With the sensitivity multiplying factor at maximum, the motion-dependent
blurriness and ruggedness look the same in all the 3 modes.
* Note: In the S/N, STD or MOVE mode, the gain control levels LOW, MID and
HIGH cannot be selected.
(4) SLOW SHUTTER
The electronic sensitivity multiplying factor can be adjusted with the L and R
buttons. x2, x4, x8, x16, x32
The higher the factor, the higher the sensitivity, but motions at maximum factor
look unnatural.
