PURPOSE:To enable the photographing of the image having the same aspect ratio as the aspect ratio of an actual photographing object by detecting the moving speed of an object just before the photographing position and synchronizing the scanning of a photographing medium therewith. CONSTITUTION:A titled device is so constituted as to synchronize automatically the scanning of a photographing medium with the moving speed of an object with a photographing device for photographing a moving object such as a slit camera, a line sensor camera or the like, wherein the video from the lens 2 of a slit camera 1 passes through a half mirror 3 and further through the slit window 5 of a slit plate 4 and is imaged on a film 6. On the other hand, the video reflected by the mirror 3 is imaged on line sensors 9, 10 which are disposed equidistantly from the film plane. A control device 11 receives the outputs from the sensors 9, 10, detects the moving speed between A-B just before the photographing position of a object 12 and feeds the film 6 in an arrow (a) direction at the speed synchronized with said moving speed. |
