Master black level setting
The master black level can be set in a range of -128 to 127. Pressing the R button increases a set
value to make the black level higher, and pressing the L button decreases a set value to make the
black level lower. For zero (0) setting, hold down both the L and R buttons for approx. two seconds.

Electronic shutter mode
When the shutter speed is Variable, operation is at the speed selected by the Variable setting (see

Long-time store mode
The camera delivers intermittent video signal output. So, to view continuous images, it is
required to use the video memory. A clear image can be attained even if the subject is
illuminated with a faint light source. As the store time increases, the degree of after-image
becomes higher.
(Note) With an increase in store time, the degree of characteristic pattern noise, white scratch,
etc. of the CCD image sensor will become higher.

：
Lock scan mode
When an image of a subject display screen having a different scan frequency is taken, a bright or
dark horizontal bar appears to roll up or down the screen.
When the shutter speed is Variable, operation is at the speed selected by the Variable setting (see
below). In the Auto CAM mode, the shutter is set to AES.
The shutter speed can be adjusted to where the horizontal bars are minimized in the display.
(Note) If the display screen scanning frequency is less than 60Hz (50Hz PAL), the rolling
horizontal bars cannot be stopped. Not settable in the Auto CAM mode.
