发明名称 Digital video camera with electronic zoom
摘要 In order to achieve a digital video camera apparatus which decreases the number of components and facilitates connection with a digital VTR, a luminance signal Y and a color signal C input form external input terminals (110, 118) are converted into digital signals by A/D converters (136, 138) by sampling these signals respectively at the sampling frequency of a digital recording/reproduction device (113) and a frequency four times the subcarrier frequency, the digital signals are selected by selectors (135, 137) together with signals Y and C from a digital signal processing circuit (106), and the selected signals are supplied to the digital signal recording/reproduction device (113). Color-difference signals are supplied after their frequency is converted into the sampling frequency of the digital signal recording/reproduction device (113) by frequency converters (139a, 139b).
