WHY IS “LIVE MOTION” AN IMPORTANT ISSUE WITH PROGRESSIVE SCAN VISUALIZERS?
“Motion” used to be the weakness of Progressive Scan cameras. Until recently they could only pick up 7.5 (or less) pictures per second. This resulted in a disturbing strobe effect on the screen, whenever something was moved in the picture and even when zoom or iris are adjusted! As it is very important for a professional presentation that motion and zooming can be shown in good quality and without any image disturbance, WolfVision uses newly developed Progressive Scan CCDs which can pick up 20 or 25 pictures per second. As a result motion looks almost as good as with PAL/NTSC “video” cameras. But the resolution is much higher!
