ABSTRACT:
Disclosed is a method of using a buffer memory for storing a plurality of picture signals wherein picture signals of more than one types are stored in an alternating manner into a buffer memory and the stored picture signals are read out at predetermined address intervals so that the picture signal of a desired type may be picked out for subsequent use for each of the types. According to the method of this invention, the number of the types of the picture signals may be arbitrary since the memory device does not have to be divided into a plurality of blocks, and all the picture signals may be stored, substantially as they are picked up at a scanning head, in a buffer memory. To eliminate any time lag in the exact timing of picking up the picture signals of various types, a sample and hold circuit may be conveniently used.
