An image motion compensator which electronically compensates for image distortion in an electro-optical system is disclosed. The electro-optical system comprises a TV camera having an image intensifier portion which includes a plurality of deflection coils disposed therein for deflecting the electron image of the TV camera as a function of the current passing therethrough; and at least one optical element for guiding the line-of-sight of the TV camera to project predetermined target images on the receiving area thereof. More specifically, accelerometers are used to sense movement of a predetermined optical element of the electro-optical system. An electronic processing unit separates from the accelerometer measurements substantially that movement of the predetermined optical element which may be causing distortion to the projected target images and governs the current passing through the plurality of deflection coils based on the separated undesirable movement measurement to electronically compensate for this image distortion in the TV camera. In addition, the image motion compensator further alters the deflection coil current as a function of variations in the high-voltage potential which is applied across the image intensifier portion of the TV camera.
