    • PURPOSE:To obtain the images approximate to actuality by selecting the parts complying with address signals among the time series video scanning signals of the projected images emitted from a video reproducing device as projected image signals and storing the signals in a temporary memory device, then successively calling out the signals and visualizing the signals to images. CONSTITUTION:The movement of the parts of the projected image assigned by an operating device 2 is converted to the address signal on the projected images by a control device 3. The parts complying with address signals among the time series video scanning signals of the projected images emitted from the video reproducing device 1 are selected as the video image signals by an image processor 4 and are stored in the temporary memory device 5. The video image signals successively called out of the temporary memory device 5 are visualized to images by a display device 6 an the visual images are projected on a screen 9. The actually photographed landscape images are made into original pictures in this way and not only the vertical and lateral movement of the images in correspondence to the fast movement of the landscape but also the rotation of the images are possible. The images approximate to the actual landscape are thus obtd.

    • PURPOSE:To display an image throughout a cruising flight by providing memories stored with a standard data base, adding the quantity of a shift in the position of an aircraft, and returning the position of the aircraft to a position on an original pattern when the aircraft files out of a pattern. CONSTITUTION:This device has the memories 21 and 22 stored with the standard data base A where the same data are arranged repeatedly, a circuit 23 which calculates the quantity of the position shift of the aircraft, and circuits 24 - 27 which add the quantity of the shift repeatedly, and the standard data base A is displayed repeatedly according to the movement of the aircraft. For example, the visual field from the aircraft covers the entire area of 4X4 patterns. The aircraft, on the other hand, files in a range shown by a dotted line and when it files out from a point C2, its position is returned to a point C1. Consequently, an invariably continuous visual field can be simulated throughout the cruising flight of the aircraft.
