Write and edit circuitry for electronic marking of displayed TV signal images
First Claim
1. Write and edit circuitry for electronic marking of electronically displayed video images comprisingvideo image generating means for generating at least one video image signal to be displayed;
- electronic marking means for providing a logic level signal to be displayed;
video overlay means connected to the electronic marking means for generating a digital bit plane overlay signal to be displayed which is synchronized with the video image signal comprising;
memory means for selectively storing the logic level signals as data bits for the digital bit plane overlay signal; and
display means connected to the video image generating means, the electronic marking means and the video overlay means comprising;
means for displaying the video image;
means for displaying the logic level signals as they they are generated; and
means for displaying the data bits stored in the memory means;
wherein the logic level signals generated by the marking means are displayed during the same scan that the logic level signals are generated and are displayed in subsequent scans if stored as data bits in the memory means.

Abstract
A new, revolutionary approach to image processing is disclosed. Using simple logic circuit elements a real time same scan video marking circuit is disclosed which is adaptable to a variety of purposes. The invention can be advantageously used as part of an integrated photogrammetric video measurement system. Using such a system, areas or distances or other graphically detectable characteristics can be displayed on a color television set for purposes of analysis and measurement. Moving pictures, made at ground locations or from an aircraft and collected in television form on a video cassette recorder, can be displayed on the television monitor and measurements of area or of distance made electronically. For the study and analysis of hard copy images, i.e. still photographs, aerial maps, x-rays and the like, an auxiliary system camera can be used which projects the picture onto the television monitor. Gray levels of the display can be detected and electronically marked for such purposes as crop measurement, infestation, weather damage, saline seep studies and the like, or, using other features of the invention, which includes a digital bit plane overlay, specific areas of the analog video display can be electronically marked on the monitor with a light pen, light pencil or cursor controls and, after visual analysis, electronically entered into calculating electronics for purposes of electronic analysis of area or distance measurements, density, heat characteristics, and the like.
