ABSTRACT:
When the recording format of an image recorded on a magnetic tape (709) is changed, a playback time period of an image signal by a REC review function is extended. Even when the recording format is changed during playback of an image signal by the REC review function, an image (409) recorded in the recording format after change can be displayed after a blue-backed screen (408) is displayed. Therefore, the user can determine whether the blue-backed screen (408) is displayed due to switching of the system or due to an unrecorded part of an image signal. Hence, the user can be prevented from overwriting a new image signal on the recorded region of an image signal by mistake.
