10.3.6 Flicker free on/off 
Flicker free can be switched off to bypass the digital frame 
store and have the video assist output with no delay.
The typical running speed for the film camera is different to 
that of the video assist. e.g. the film camera runs at 24 fps 
and the video assist at 25 fps for PAL or 30 fps for NTSC. 
Without flicker processing this speed difference causes 
varying brightness between successive individual video 
images. To eliminate this so called flicker, video images are 
stored at the speed of the film camera into the video frame 
storage and recalled in the speed of the video system. This 
storage might cause a slight delay, which is not desirable 
in some time-crucial conditions, e.g. motion control or 
shooting of a pop video. Therefore it is possible to switch 
the flicker free system off. This will eliminate the delay. 
However, flicker will occur in this mode.
