ABSTRACT:
A process and apparatus for the remote pickup and reproduction of image of static or dynamic objects in which dark regions of a target provide outputs below a threshold value which are normalized or averaged through a divider during intervals of line scan interruption brought about by the detection of a below threshold level. The system, therefore, allows integration during the interval and by averaging and integrating values permits discernment of features which might otherwise be obscured by a leveling effect in dark regions.
