专利汇可以提供System for band conversion of color picture signal专利检索,专利查询,专利分析的服务。并且A system for converting a simultaneous color picture signal of a wide band into a field sequential color picture signal of a narrow band and a system for reconverting a field sequential color picture signal of a narrow band into a simultaneous color picture signal of a wide band. The former system comprises memory means capable of varying the writing speed and the reading speed and having the memory capacity capable of storing a picture signal of one frame, means for switching two input signals to output them at every field period, means for obtaining one of the two chrominance signals of a simultaneous color picture signal at the odd numbered field and obtaining the other chrominance signal at the even numbered field by means of the switching means, and means for writing at a high speed and reading at a low speed in and from the memory means the luminance signal and the chrominance signals different at every field of the color picture signal. The latter system comprises memory means capable of varying the writing speed and the reading speed, having the memory capacity capable of storing a picture signal of one frame, capable of repeatedly reading the stored signal therefrom, and capable of simultaneously reading therefrom signals differing by one field period from each other, means for writing a signal of one frame of a field sequential color picture signal of a narrow band in the memory means at a low speed, and means for repeatedly reading the stored signal at a high speed and obtaining two chrominance signals from the simultaneously read out signals differing by one field period.,下面是System for band conversion of color picture signal专利的具体信息内容。
