摘要： A magnetic recording/reproducing apparatus equipped with an image sensor, has a camera portion having an A/D converter for converting a signal from an image sensor into a digital signal and a first digital processor for receiving an output of the A/D converter and for digitally processing thereof. A VTR portion of a helical scan type mounts at least two or more of magnetic heads for recording/reproducing a FM modulated luminance signal and a low band converted chrominance signal. A second digital processor processes a video signal of the VTR. A switching circuit is provided in a preceding stage of the A/D converter. The image sensor signal, an external video signal and a reproduced signal from the magnetic heads are exchanged. The output of the A/D converter is inputed to the second digital processor, and a sampling clock of the A/D converter is exchanged to the most appropriate clock for the respective image sensor signal, the external video signal and the reproduced signal from the magnetic heads.

摘要： Image data photographed by a video camera 20 are compressed by a compression and decompression circuit 5, the compressed image data are recorded in an incorporated type semiconductor memory 6 or disk-type memory 13 fixed in the video camera 20 and the recorded image data are transferred to an external recording device 23. Further, the external recording device 23 records the transferred image data in a data storage while they are being compressed. The video camera 20 receives, decompresses and converts into a television signal the compressed image data read by the external recording device 23 in reproducing them. A video camera system capable of recording and reproducing long hours of image data by using a video camera having an ultra small size comparable to that of an 8 mm video cassette can be realized by using such a construction.

摘要： A video camera is provided not only with means for receiving any general captured images but also with means for receiving images from any other video input source. The video camera is also provided with an image input arbitration section that captures, after arbitration, video data coming from these two input means, and stores the resulting data into a memory. As such, when the video input source is a video output terminal of a car navigation system, the screen of the car navigation system, i.e., map information, can be stored in a memory together with a user's captured image. When the video camera is used for monitoring, data capturing into a memory is also enabled when the video input source is a medium already carrying therein map image data, e.g., USB flash memory and SD card, and means for reading the map image data from the medium. The data in the memory is subjected to a process of compression and encoding as moving images so that the image of position information and the user's captured image can be processed as a set of moving images. This accordingly enables to provide a system and method for recording and reproducing a set of moving images of the combination of an image of position information and a user-captured image with no need for a complicated process.
