1. Process for producing a television receiver screen image which appears three-dimensional when viewed through anaglyphic eye glasses, the image being produced from monoscopic image signals representing monoscopic images in timed sequence, by superimposing two partial images which are mutually offset by a selected partial image distance, in complementary colours matched with the anaglyphic eye glasses, each of the partial images being derived in the form of a different colour excerpt from each the same monoscopic image, characterized in that the partial image distance is created by mutually time-delaying the partial image signals which produce the associated partial images.
