Abstract
Abstract In a system including a still video camera and a playback device capable of being connected thereto, the playback device stored track information (such as data representing the field/frame recording and the envelope peak position) detected in a playback operation in a memory thereof corresponding to a track number. When the power of the playback device or the like is turned off, the track information is transferred from the playback device to the camera side and is stored in a memory of the camera side. When the playback device achieves thereafter a playback operation, the track information is again transferred to the playback device so as to be used for the playback operation. The track information can also be used in an erase operation on the camera side or in the playback device. In addition, track information used in a recording operation of the camera is stored in a memory thereof corresponding to a track member. When the playback device is connected to the camera and a mode thereof is changed over to a playback mode, the track information is transferred from the camera to the playback device, thereby storing the track information in a memory of the playback device. The track information is used when the playback device conducts a playback operation.

Claim 1
Independent Claim
221 words
A method of an operation in a still video camera system having a still video camera comprising the steps of: producing a still video signal representing an objective image by a solid-state imaging element of the still video camera; recording said still video signal on a predetermined track or in two predetermined tracks of a rotating magnetic recording medium having a plurality of tracks; reproducing a signal read from the predetermined track or the two predetermined tracks of the magnetic recording medium by a playback device capable of being detachably connected to the still video camera; processing by the playback device said signal read from the predetermined track or the two predetermined tracks from the magnetic recording medium sent from the still video camera; storing track information detected in association with a playback processing in a playback memory thereof corresponding to a track number; controlling said playback processing by designating one of said plurality of tracks to be played back and accessing said one track designated; and transferring said track information stored in said playback memory from the playback device to the still video camera when a main power off operation is conducted in either one of the still video camera and the playback device and storing the track information in a still video camera memory of the still video camera.
Claim 2
