Abstract
A digital video image splitter permits the top portion of a closed-circuit television (CCTV) display to be shifted right (delayed) or left (advanced) with respect to the stationary bottom portion of the display. The user controls the vertical level (distance from top to bottom of display) at which the split is seen on the display, and the amount of shift from controls in the system. Shifting of the image permits the width of an object displayed on the display to be measured. By matching opposite edges of the object in the display, the width of the displayed object is equal to the amount of shift. A single raster line at the level of the split is available as digitized image intensity data, and represents the intensity profile of the video display, including the object being measured, along that raster line.
