专利汇可以提供Separation color recorder system专利检索，专利查询，专利分析的服务。并且A system to provide for the production of standard motion picture color film from a color video signal or color information composed of color components. The color video signal is decoded into its separate red, green and blue components, which components are used to provide a special form of field sequential color consisting of a repeating color group where such group contains at least one field of each of the red, green and blue components and at least one additional field of at least one of the red, green and blue components. The special form of field sequential color is recorded on standard black and white film as a black and white separation master at either 60 field per second or 50 fields per second, depending upon the field rate of the video signal, which recording is accomplished using a continuous film motion electronic beam recorder. A standard color film is made from the separation master by exposing each frame of the color film in sequence to red, green and blue separation images using appropriate color filters with the separation master.，下面是Separation color recorder system专利的具体信息内容。
