ABSTRACT:
A digital type VTR or the like image signal recording and reproducing apparatus using sub-Nyquist sampling on the image includes an interpolator circuit for carrying out interpolation on a signal based on correlation between image signals in neighboring fields. The interpolator circuit is by-passed when high speed reproducing is carried out.
