This goes against the trend towards smaller and lighter weights. Therefore, conventional electronic cameras are not only equipped with a playback function and video means, but can also be used to record a recording medium taken outdoors indoors using a camera and a television receiver. Since the electronic camera is configured for viewing only one recording, only the recording head is used, and the erasure is performed by the playback device, there is the inconvenience that additional recording cannot be made.

In other words, the conventional partial camera is f, as shown in Figure 6.
