ABSTRACT:
A still picture signal conversion apparatus converts a still picture signal reproduced in the form of an electric signal from a video tape or disk, still picture video camera or the like to a low-velocity narrow-band signal suited for use in a facsimile system utilizing the ordinary telephone circuit or a hard copying apparatus and performs the desired trimming operation on the signal when delivering the same. A selected portion of each horizontal scan line is taken out as a sampled digital picture signal and the number of the horizontal picture elements is compensated for by the method of sampling frequency adjustment or weighted interpolation. To effect the vertical trimming, the digital picture signal is stored temporarily every horizontal scan line in a plurality of memories so that portion of the signal to be retained by the trimming is selectively read out and the deficient number of scan lines is compensated for by the method of weighted interpolation.
