Abstract
A vertical motion detector for a TV system motion detector. The circuit operates by delaying each motion indicator signal by multiple units of the time required for one full horizontal line sweep. If vertical motion occurs, the delayed indicator will output from the delay at the same time another indicator occurs. These signals are fed to multiple AND gates so that several coincident signals are required to produce an alarm. A switching circuit permits selection of the number of vertical motion indicators required for an alarm.
