Zoom in on video, magnify or enlarge video images or pictures with the Model 425 series. This Electronic Video
Zoom, Video Magnifier or Video Enlarger can enlarge or magnify, up to ten times, a selected portion of an NTSC
color video picture or image to fill the entire display for closer examination. The Video Zoom, Video Magnifier,
Video Enlarger can operate on a live video picture or video image or one frozen in its display memory.
The video zoom ratio is controlled in 64 steps from 1:1 to 10:1 by means of a knob. Any portion of the input
video picture or image may be selected for enlargement or magnification using four pushbutton position controls
that move the selected region up, down, left, or right.
The video freeze function can be invoked by means of a front panel switch or a contact closure at the unit’s
external freeze input. A bypass switch allows viewing of the full input picture without disturbing video zoom
and freeze settings.
An additional switch provides filtering of motion artifacts caused by the interlaced nature of NTSC video.
This is useful when features in the picture can not be held motionless long enough for the unit to freeze
a video image.
