<p>PURPOSE:To provide a camera integrated recording and reproducing device by reducing the number of the two A/D converters used for post stages of t switches for color difference signals. CONSTITUTION:Color difference signals R-Y, B-Y generated at a sampling frequency fmk in a camera signal generating section A are converted into 4fSC at frequency conversion circuits 6, 7 and a luminance signal Y is converted into an analog signal by a D/A converter 4. On the other hand, a chroma signal C received externally is sampled by an A/D converter 13 by using the frequency 4SC and converted into a digital signal, a color difference signal is demodulated by a demodulator 14 and fed to switches 15-17 with the luminance signal Y received externally and selected with each signal from a camera. The Y signal obtained from the switches 15-17 is converted into a digital signal by an A/D converter 18 by using a 13.5MHz signal and the R-Y, B-Y signals are converted into 13.5MHz signals by frequency conversion circuits 19, 20 and they are fed to a recording and reproducing section 33 together with the signal Y and processed by the 13.5MHz signal and recorded on a magnetic tape 35.</p> |
