Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera-integrated magnetic recording apparatus for recording video data at the start of recording on a cassette tape so that the recorded contents can be confirmed without reproducing the video tape.

[0002]

2. Description of the Related Art Conventionally, there is a camera-integrated magnetic recording device having a function of recording video data at the start of recording on a video tape so that the recorded contents can be confirmed when the video tape is reproduced.

That is, when a video is recorded on a video tape by a magnetic recording device with a built-in camera, a still image at the start of recording, a time code at the start of recording, and a recording date, a title, a sub-item such as a photographer, etc. Information is temporarily written to a semiconductor memory built in the camera-integrated magnetic recording device or a semiconductor memory card detachably attached to the camera-integrated magnetic recording device, and the semiconductor memory or semiconductor is separately recorded by a special operation. The data temporarily stored in the memory card is read and recorded on the tape.

Thus, when the video tape is reproduced by the camera-integrated magnetic recording device or the dedicated video editing device, the viewfinder of the camera-integrated magnetic recording device,
The sub information and the still image at the start of recording are read from the video tape and displayed on the monitor screen of the video editing device.

In this way, before actually reproducing the video tape, the contents of the video tape are confirmed, and when the cassette tape on which the desired image is recorded is found, the cue button or the like is pressed, Based on the time code of the displayed data, the relevant part of the video tape is searched and played.

Further, in a non-linear editing machine, a still image at the start of recording is collectively read from a video tape, all the still images are displayed on the screen, and a mouse or the like is used to select the corresponding video tape. Search for the part and perform playback and rendering.

[0007]

However, in the case of the conventional camera-integrated magnetic recording device, a still image at the start of recording is
For example, it is written at the end of the video tape. That is, the still image at the start of recording is temporarily stored in a semiconductor memory built into the camera-integrated magnetic recording device or a semiconductor memory card detachably attached to the camera-integrated magnetic recording device, and the user records it. When ejecting the video tape after finishing, unlike the normal cassette tape eject operation, a special eject operation that involves writing a still image, for example, pressing the eject button while pressing the still image writing button, etc. Perform the operation.

Further, when displaying a still image at the start of recording for confirming the contents, it is necessary to advance the video tape to the position where the still image is written. Therefore, there is a problem in that it takes time to display a still image, and it is not possible to smoothly confirm the contents of the video tape. In addition, it is necessary to advance the video tape to the read position of the still image at the start of recording, which causes a problem that power is consumed in the drive system of the video tape.

Further, due to the miniaturization of the semiconductor memory card, the interface is a serial system, the data transfer rate is slower than the recording rate of the tape, special processing is required, and the addition of the temporary storage memory and the control complexity are complicated. However, there is a problem in that cost and power consumption increase as a result. Further, there is a method of managing a semiconductor memory card used for temporary storage and a cassette tape in a pair, but there is a problem that management becomes complicated.

According to the present invention, it is possible to reliably and easily write a still image at the start of recording, and at the time of confirming the contents of the video tape, the still image at the start of recording is quickly displayed.
The contents confirmation work can be performed smoothly, and the still image at the start of recording and the sub information and the captured video are recorded on the same cassette tape, which simplifies data management and saves power. It is an object to provide a recording device.

That is, when the power is turned on, the free space of the semiconductor memory 30 is detected, and the number of scenes of still images that can be recorded is displayed on the viewfinder display 28 or the like. Then, the number of recordable scenes is reduced every time one scene is recorded, and the remaining recordable scene number is displayed on the viewfinder display section 28 or the like. Furthermore, the number of remaining recordable scenes is, for example, 3
A warning may be displayed when the number of sheets is reduced.

When writing a still image at the start of recording, the system control unit 13 causes the semiconductor memory 30 to operate.

For example, a scene that the user wants to mark is displayed. A still image of the scene may be written in the semiconductor memory 30 by pressing a predetermined button of the camera-integrated magnetic recording device at the time of shooting. If you think that shooting has failed, you can use this function to return to that scene and shoot again,
The tape consumption can be reduced. In addition, when the recorded image is not recorded, that is, when there is a scene to be marked in the middle of the shot, by pressing a predetermined button while reproducing the scene, it is written in the semiconductor memory 30. May be.
