A video signal-processing device includes an arrangement for detecting film scratches. To distinguish slant scratches in the video signal from other scratch-like image structures in a safe manner, the arrangement for detecting scratches is intended to determine whether at least the section of a scratch extends from the lower margin of an image N-1 preceding a current image N into the upper margin of the current image N, and whether at least a further section of a scratch extends from the lower margin of a current image N into the upper margin of an image N+1 succeeding the current image N.
