Abstract
Apparatus for generating an electrical signal representative of differences in radiant energy of adjacent pixel points of a scene is described incorporating a first and second sensor for sensing radiant energy and a differential amplifier for taking the difference of the output signals of the sensors. The invention overcomes the problem of storing and transferring large signals from the sensors by transferring the difference signals only.
