It is known to have a function of playing back a recorded image from a recording medium. This type of video camera recorder is mainly used for recording a real image at any place regardless of whether it is outdoors or indoors, and has become widespread in recent years. On the other hand, the VCR is equipped with a TV tuner for receiving a television broadcast signal, a re-recording circuit, a re-recording mechanism, etc., and is mainly used for recording / playback of a television broadcast program or video at a fixed place such as indoors. It is used to play back the video recorded by the camera recorder.

[0003]

As described above, while the conventional video camera recorder has an advantage that it can be used at any place, it cannot record a television broadcast. On the contrary, the VCR is While it has the advantage of being able to record television broadcasts, it has the disadvantage that it cannot be used anywhere such as on the go. Also, some video camera recorders can be connected to an external tuner, but even in the case of that type of video camera recorder, the frequency of the external TV tuner is exclusively for Japan, so There was a problem that I could not record the television broadcast on my trip. Therefore, an object of the present invention is to provide a portable video camera recorder device with a built-in TV tuner that enables viewing and recording of television broadcasts.

[0004]

In order to achieve the above object, a portable video camera recorder device with a built-in TV tuner according to the present invention comprises an optical system for capturing a subject image and the subject image captured by the optical system. An image pickup element for converting into a video signal, a playback recording system for recording a video signal from the image pickup element on a recording medium, and playing the video signal recorded on the recording medium from the recording medium, and the image pickup element and the playback recording system In a portable video camera recorder device including a viewfinder that displays an image corresponding to the image signal from the image signal from, a TV tuner that receives an image signal of a television broadcast, the image pickup device, and the TV tuner. A connecting means for selectively connecting either one to the playback recording system and the viewfinder is provided.

The present invention also provides the above optical system, image pickup device,
A charge housing a camera housing containing a playback / recording system and a viewfinder, a rechargeable power supply housed in the camera housing, and a charging circuit detachably attached to the camera housing to charge the power supply. An adapter is further provided, and the TV tuner is housed in the charge adapter. further,
In the present invention, the video signal of the television broadcast is NTSC.
It is assumed that the TV tuner is configured to be capable of receiving video signals of television broadcasting of all frequencies according to the NTSC system.

[0006]

When a subject image captured by the optical system is recorded, the image pickup device is connected to the reproduction recording system and the viewfinder by the connecting means to record the subject image on the recording medium in the reproduction recording system. , The image of the subject can be displayed on the viewfinder, and the recording and shooting can be performed as usual. When recording a television broadcast, by connecting the TV tuner to the playback / recording system and the viewfinder by the connecting means, the image by the video signal of the television broadcast received by the TV tuner is recorded in the playback / recording system. The video of the broadcast program can be recorded while checking the broadcast content by displaying the broadcast video on the viewfinder. Therefore, the video of the broadcast program can be recorded at any place regardless of whether it is outdoors or indoors, and the range of use of the portable video camera recorder device can be widened and the frequency of use can be increased. In addition, by configuring the TV tuner to support not only frequencies of Japanese broadcasting stations but also frequencies of foreign broadcasting stations, it will be possible to record necessary programs even when traveling abroad, improving convenience. Can be achieved.
