PURPOSE:To discover, for instance a turbo living on the sea bottom or a sufferer drifting on the sea or the like, easily using a TV camera by providing a flashing equipment by which lightings are turned on-and-off repeatedly and successively in such a manner that the lighting period of each lighting is different, a synthesizing circuit by which a colored image signal is produced with an image signal given by the TV camera and a color signal given by the lighting and a reproducing member by which a colored image is produced. CONSTITUTION:An object to be detected is illuminated from four direction by turning on the lightings 2-5 successively by rotating a rotary switch 10. A TV camera gives an image signal according to the shape of the detected object and the image signal is put into color signal output circuits 13-15 through an image amplifier 16 and the like of a color television receiver 8. For instance, when the rotary switch 10 gets contact with a contact 2A, the lighting 2 is turned on and, because the voltage of a lighting source 12 is applied to the red signal generating circuit 13 through a resistor 11a and an OR-circuit 19, the shape of the detected object illuminated by the lighting 2 is reproduced on a CRT18 as a red image. |
