ABSTRACT:
Disclosed are a method and apparatus for making area measurements of an image on a kinescope screen. Scan lines of the kinescope are divided into a series of pulses by a switching device. The pulses within the image are counted. The number of pulses counted within the image is an indication of the area of the image. The size of the image may be determined in conventional units by comparing the number of pulses counted within the image to the number of pulses known to represent a given area.
