PROBLEM TO BE SOLVED: To provide a video camera having automatic focusing function and an external video signal input function while advantages in cost are kept. SOLUTION: Since photographing optical system is not adopted, it is noted that an A/D converter used for position detection of a focus lens is not used during recording of an outer video signal. By switching an input signal to one A/D converter (2)112 for the time of external video signal recording mode and the time of photographing mode, an A/D converter for converting the video signal from outside into digital data, and an A/D converter for detecting the position of the focus lens are used in common so that an increase in number of expensive A/D converters, can be restricted.
