ABSTRACT:
On tape carrying a mixture of a static image recording portion and a dynamic image recording portion, ID (identification) signals are recorded to specify only a specific static image for retrieval. During image recording, the PP (Photo/Picture) ID signal indicative of the static image recording portion is automatically recorded on the static image recording portion for a sufficiently long duration to allow its detection during quick search. When a desired static image is determined on the screen, the INDEX ID signal indicative of the static image is subsequently implanted only in the static image recording portion. Thus, the desired static image can be retrieved by first searching the PP ID signal quickly to locate the static image recording portion and then searching the INDEX ID signal in the static image recording portion. These two ID signals can also be subsequently implanted in the dynamic image recording portion to retrieve any one frame image.
