摘要： A video signal processing apparatus has a phase-locked loop which includes a quartz resonator, a voltage-controlled oscillator connected to the quartz resonator and oscillating at an oscillation frequency whose fundamental value is determined by the quartz resonator, and a horizontal sync signal lock circuit comparing a phase of a horizontal sync signal and a phase of an output signal from the voltage-controlled oscillator and controlling the oscillation frequency of the voltage-controlled oscillator in response to a difference between the phases of the horizontal sync signal and the output signal from the voltage-controlled oscillator. The video signal processing apparatus also has a device for modulating a video signal by use of the output signal from the voltage-controlled oscillator.

摘要： A phase detection device with low power consumption capable of accurately detecting that an object has moved, and returning from an intermittent energized mode to an always energized mode is provided. The phase detection device according to the present invention comprises a first phase detector for detecting a phase of an object, a second phase detector, a power supply section having an always energized mode for always supplying a power to the first and the second phase detectors, and an intermittent energized mode for intermittently supplying the power to the first and the second phase detectors, and a control section for, in the intermittent energized mode, storing detection phases of the first phase detector and the second phase detector just before shifting to the intermittent energized mode from the always energized mode, and when both detection phases of the first phase detector and the second phase detector change from stored detection phases of the first phase detector and the second phase detector, changing the power supply section from the intermittent energized mode to the always energized mode.
