Abstract

In a known process for enlarging the spatial delimitation of images, the enlargement of the spatial or vertical deflection is combined with purely digital enlargement of the signal in the horizontal direction. To reduce the spatial delimitation of images, a) the data are recorded in a storage by prior expansion. The image data are expanded during read-out; b) the data are expanded as they are being recorded in the image storage. The data are reproduced by partial read-out.
