Claims
- 1. A color image signal recording apparatus for recording a color image signal including a color burst signal, horizontal and vertical synchronizing signals and having a blanking portion on a recording medium, comprising:
- (A) generating means arranged to input the image signal and to generate a sampling clock signal which is synchronized with the horizontal and vertical synchronizing signals in the color image signal, and a one pulse signal which is different from the color burst signal, the horizontal and vertical synchronizing signals included in the color image signal and which indicates a reference phase synchronized in phase with the sampling clock signal, and a pilot signal which is different from the color burst signal, the horizontal and vertical synchronizing signals and the one pulse signal and which has a single frequency;
- (B) sampling color image signal forming means arranged to input the color image signal and to effect sampling of the input color image signal in synchronism with the sampling clock signal generated by said generating means, thereby forming and outputting a sampling color image signal;
- (C) processing means for adding the one pulse signal generated by said generating means to the sampling color image signal outputted from said sampling color image signal forming means at a portion of said sampling color image signal which corresponds to the vertical blanking portion of the color image signal and continuously frequency-multiplexing the pilot signal generated by said generating means to the sampling color image signal outputted from said sampling color image signal forming means; and
- (D) recording means for recording on said recording medium the sampling color image signal outputted from said processing means.
- 2. A color image signal reproducing apparatus for reproducing a color image signal from a recording medium, comprising:
- (A) reproducing means for reproducing a sampling color image signal from the recording medium on which the color image signal is recorded and for outputting the signal as a reproduced sampling color image signal, the sampling color image signal being formed by sampling a color image signal including a color burst signal, horizontal and vertical synchronizing signals in synchronism with a sampling clock signal, a portion of the sampling color image signal which corresponds to the vertical blanking portion of the color image signal being added to a one pulse signal which is different from the color burst signal, the horizontal and vertical signals included in the color image signal and which indicates a reference phase synchronized in phase with the sampling clock signal, and further the sampling color image signal being continuously frequency-multiplexed with a pilot signal which is different from the color burst signal, the horizontal and vertical synchronizing signals and the one pulse signal and which has a single frequency;
- (B) one pulse signal separating means for separating the one pulse signal from the reproduced sampling color image signal outputted from the reproducing means;
- (C) pilot signal separating means for separating the pilot signal from the reproduced sampling color image signal outputted from said reproducing means;
- (D) re-sampling clock signal generating means for generating a re-sampling clock signal for re-sampling the reproduced sampling color image signal outputted from said reproducing means, the re-sampling clock signal being synchronized in phase with the pilot signal frequency-multiplexed with the reproduced sampling color image signal; and
- (E) phase control means for controlling a phase of the re-sampling clock signal generated by said re-sampling clock signal generating means in accordance with the one pulse signal outputted from said one pulse signal separating means.
- 3. An apparatus according to claim 2, further comprising:
- (F) re-sampling image signal forming means for re-sampling the reproduced sampling color image signal outputted from said reproducing means in synchronism with the re-sampling clock signal outputted from said phase control means, thereby forming and outputting a re-sampling color image signal; and
- (G) memory means for storing the re-sampling color image signal outputted from said re-sampling color image signal forming means.
- 4. An apparatus according to claim 3, wherein said memory means includes
- (1) a memory circuit for storing the re-sampling color image signal output from said re-sampling color image signal forming means; and
- (2) a memory control circuit arranged to successively assign a writing address for the re-sampling color image signal, to store the re-sampling color image signal in said memory circuit and to read out the re-sampling color image signal stored in said memory circuit in synchronism with an accurate clock signal.
- 5. An apparatus according to claim 4, wherein said memory control circuit is arranged to reset the writing address assigned to said memory circuit in accordance with the one pulse signal output from said one pulse signal separating means.
