PURPOSE:To obtain plural images within scanning time by demultiplexing a picture from an object into plural image pickup devices and impressing a shutter driving voltage impressed to each image pickup device while shifting it by a prescribed time to increase apparently a repetitive shutter speed. CONSTITUTION:An image of the object formed by an incident lens 10 is demultiplexed into three directions by a prism 24, each output is applied to an image intensifier 16 and inputted to an image pickup device 12 such as image pickup tube via a fiber 14. A voltage for driving a shutter of the image intensifier 16 is supplied from shutter driving circuits 18a-18c driven by a signal outputted sequentially from a trigger signal via delay circuits 26a, 26b. The time of driving voltage from the circuit 18a to the circuit 18c is shorter than the scanning image forming time, each object image of image pickup devices 12a-12c is read at a reading circuit 20, recorded in a picture memory 28, the content of the memory is read selectively by a selection switch 30, analyzed by a picture analyzer 32 and displayed on a monitor television 34. |
