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. one seconds.

2)SHUTTER : Electronic shutter mode

• OFF

: Electronic shutter does not operate.

• PRESET

: Shutter operates at the Preset speed. Select speed from among 1/100 (1/60 PAL),

 

1/250, 1/500, 1/100, 1/2000, 1/4000, 1/10000, 1/20000, 1/40000 and 1/100000 second.

• VARIABLE

: The shutter speed is VARIABLE value under a line.

a)8 to 1/30 (1/25 : PAL) : Long-time frame store mode:

4 to 1/30 (1/25 : PAL) : Long-time field 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.

b)1/60.38 (1/50.31: PAL) to approx 1/100,000 : 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. 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.
