Abstract
A video signal recording and reproducing system having image pick up means for converting an optical image to electrical signals, forming means for forming video signals from the electrical signals obtained from the image pick up means, recording and reproducing means for recording video signals on a recording medium and reproducing the video signals from the recording medium, delay means for producing input signals with a prescribed length of delay time, and change over means for incorporating the delay means into the forming means or the recording and reproducing means selectively.
Claims23
A video signal recording and reproducing system, comprising:
- (a) image pick-up means for converting optical images to an electrical signal;
- (b) separating means for separating color signals from the electrical signal obtained by said image pick-up means;
- (c) forming means for forming a video signal which includes a luminance signal and a chrominance signal by using the color signals;
- (d) recording means for recording the video signal on a recording medium;
- (e) reproducing means for reproducing the video signal from the recording medium, said reproducing means including a processing circuit to handle the video signal;
- (f) delay means for producing input signals with a predetermined period of delay;
- and
- (g) changeover means for incorporating said delay means selectively into said separating means and said processing circuit.
A video signal recording and/or reproducing system, comprising:
- (a) image pick-up means for converting optical images to the electrical signals, said image pick-up means including a charge transfer device;
- (b) separating means for separating color signals from the electrical signal obtained by said image pick-up means;
- (c) forming means for forming a video signal which includes a luminance signal and a chrominance signal by using the color signals;
- (d) recording and/or reproducing means for recording the video signal on a recording medium and/or for reproducing the video signal from the recording medium, said recording and/or reproducing means including a processing circuit to handle the video signal;
- (e) delay means for delaying at least part of the video signals, said delay means being incorporable into said processing circuit and including a charge transfer device;
- and
- (f) clock generation means for generating a clock signal driving both the charge transfer device of said image pick-up means and the charge transfer device of said delay means.
A video signal recording and/or reproducing system, comprising:
- (a) image pick-up means for converting optical images to electrical signals;
- (b) separating means for separating color signals from the electrical signal obtained by said image pick-up means;
- (c) forming means for forming a video signal which includes a luminance siganl and a chrominance signal by using the color signals;
- (d) recording and/or reproducing means for recording the video signal on a recording medium and/or for reproducing the video signal from the recording medium, said recording and/or reproducing means including a processing circuit to handle the video signal;
- and
- (e) clock generation means for generating a clock signal to determine the timing of the operations of both said image pick-up means and said recording and/or reproducing means.
