摘要 |
<p>A magnetic recording/reproducing apparatus equipped with an image sensor, comprising: 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 said A/D converter and for digitally processing thereof; a VTR portion of a helical scan type mounting 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 for processing an video signal of the VTR; and a switching circuit provided in a preceding stage of said A/D converter, whereby the signal from said image sensor, an external video signal and a reproduced signal from said magnetic heads are exchanged, the output of said A/D converter is inputted to said second digital processor, and a sampling clock of said A/D converter is exchanged to most profitable clock for the signal from said image sensor, the external video signal and the reproduced signal from the magnetic heads, respectively. <IMAGE></p> |
