ABSTRACT A time axis correcting device for removing change in time axis in an input video signal includes a video signal memory unit; a write-in control unit operable in response to a sampling command signal to write the input video signal in the video signal memory unit at a write-in timing conforming to the change in time axis in the input video signal; a read-out control unit for reading out the video signal from the video signal memory unit at a predetermined read-out timing; a read- only memory for storing sampling data of a sine wave; a reference signal sampling circuit for sampling the reference signal from the input video signal; an address control unit for calculating the difference in phase between a sampling point and a reference position for the sampling point according to a sampling value of the reference signal sampled from the input video signal and also for addressing the read- only memory according to the difference in phase to cause the read-only memory to output a corrected reference signal; and a signal converter for converting the corrected reference signal into the sampling command signal.
