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.

摘要： An imaging apparatus which can correct a shaking of the hand whether a moving picture is taken or a still picture is taken. Exposure is carried out within a shorter time than a predetermined exposure time to output a charge. Exposure and delivery of charge is carried out plural times to accumulate charges. An address for accumulation is changed in accordance with information of a shaking occurring within the shorter time and a signal due to the shaking and a signal before the shaking are accumulated at the address. Alternatively, a camera-shake is detected by using a sensor such as a gyroscope adapted to detect an angular velocity or an acceleration of a shaking of the imaging apparatus itself.

摘要： A digital recording/reproducing video camera apparatus which externally receives analog video and audio signals as a standard video signal for data compression and recording. Selection switches for switching between a camera pick-up mode and a line input mode are switched to their terminals a in the camera pick-up mode and switched to their terminals b in the line input mode. An output signal of a CCD is sent via an amplifier, the switch and an A/D converter to a digital signal processing circuit to generate color and luminance signals. The generated color and luminance signals are fed to a data compression/expansion circuit to remove redundant parts therefrom and then sent to a HDD for recording. In a line input record mode, a line input signal is supplied through the switch and A/D converter to the digital signal processing circuit to generate the color and luminance signals. The generated color and luminance signals are fed to the data compression/expansion circuit to remove redundant parts therefrom and sent to the HDD for recording. The video camera apparatus may include a video signal processing circuit for detecting a time base error in 1 sampling period or less of the synchronization signal caused by performing Y/C separating/demodulating operations on a digital signal and moves a center of a video part in response to its detection result.
