PURPOSE: A device for correcting image signal jitter is provided to automatically control jitter components by controlling operation speed of a phase locked loop, thereby making image signals slow. CONSTITUTION: A device for correcting image signal jitter includes a dividing element dividing image signals input from the outside into horizontal and vertical synchronous signals, a phase locked loop(22) outputting the horizontal synchronous signal as jitter-corrected horizontal synchronous signal by differentiating operation speed of the phase locked loop by a control signal, a counting part(23) counting the image signals for judging the kind of the image signals input from the outside, so that the counting part outputs the control signal controlling operation speed of the phase locked loop.
