Abstract
A video signal sampling circuit searches the optimum sampling frequency and phase of the sampling clock signal by detecting level changing points in the sampled video signal in the horizontal direction with the sampling frequency varied every predetermined phase. The saturated maximum count of the level changing point provides the optimum sampling frequency and optimum phase of the sampling clock signal. The video signal sampling circuit automatically sets the optimum sampling frequency and phase of the sampling clock signal in accordance with the result of searching. The video display including the video signal sampling circuit is also disclosed.
