A Device for Compensating the Linear Shift of an Image During Oblique Photography with a Successive-Frame Aerial Camera

摘要

The object of the invention is a device for compensation of the linear shift of an image during oblique photography by a successive-frame aerial camera by means of sequential exposure of the zones of the frame, which are parallel to the principle horizontal plane of the photograph, containing a focal plane continuous action shutter, a two-wedge compensator and electric motor; and which is distinguished by the fact that for the purpose of fulfilling the required law of change of the rate of compensation along the field of the frame during uniform movement of all elements, the focal plane shutter is kinematically connected through the differential reducer with the electric motor of a two-wedge compensator.
