A drop out compensation circuit for resolving the unnaturalness of the pictorial image due to a long period drop out compensation is disclosed. This drop out compensation circuit comprises a drop out detecting circuit, a delay circuit for delaying a drop out detected output, and a circuit for limiting the drop out compensation to the delay time period by the delay circuit in response to the drop out detected output and the delay signal of the delay circuit. Accordingly, the drop out compensation is performed only within a range wherein it is visually natural, so that unnatural pictorial image does not appear.
