ABSTRACT:
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.
