Color television system for processing signals from a television camera

A method of recording an image of a scene onto cinematographic color film comprises forming a number of successive partial images through a single lens system onto each single frame of the film, the successive partial images being recorded in light of different characteristics, for example different colors. The film is projected using a conventional projector, and when viewed through appropriate filters, gives a stereo scopic effect. To get an optimum effect, the sequence in which the images are recorded should be appropriate to the predominant direction of horizontal movement in the scene. Accordingly in one form of the invention, each image is divided into a number of areas, each area in successive images being recorded in light of different characteristics, and each image having different areas recorded in light of different characteristics. In another form of the invention, two successive series of images are formed on each time, or on alternate frames, the first series of images being formed sequentially in the reverse order. Filter members for use in a film camera for carrying out the method are described.

Recording and reproduction of images

A method of recording an image of an object onto cinematographic color film comprises forming a number of successive images of the object through a single lens system onto each frame of the film, the successive images being recorded in light of different characteristics, for example different colors. In a preferred embodiment, each frame of the film is exposed successively to light of two or three different colors. The film is projected using a conventional projector, and when viewed through spectacles consisting of two appropriate filters gives a stereoscopic effect. The method can be used to produce a film which can also be viewed without spectacles, and is found to give enhanced sharpness and color saturation. The invention also includes a moving film camera having a mechanism for interposing a number of filters in the optical path successively during exposure of each frame so that successive images are overlaid on each frame. In one embodiment a rotatable shutter member having a transparent portion consisting of a number of filters is provided. The shutter member may replace the rotating shutter of a conventional film camera. Several different forms of shutter member are described.
