PROBLEM TO BE SOLVED: To provide a device that automates adjustment of the frequency and the phase of a sampling clock, when a digital video signal is employed. SOLUTION: This automatic adjustment device is provided with an A/D converter section 101, that receives and samples a video signal for converting the signal into digital video signal data, a storage section 102 that stores the video signal data, an arithmetic processing section 107 that reads the video signal data for adjusting the frequency and phase of a sampling clock, a sampling clock generating section 105 that generates and outputs the sampling clock, a frequency control section 106 that controls the setting a frequency of the sampling clock from the sampling clock generating section 105 by receiving frequency control data from the arithmetic processing section 107, a delay section 103 that supplies a signal delaying the sampling clock to the A/D converter section 101, and a phase control means 104 that applies setting control of the delay in the sampling clock in the delay section 103 to the control data from the arithmetic processing section 107.
