This paper describes a laser telecine which has been developed for transferring film images into HDTV signals with high picture quality. In this equipment the film image is directly scanned by a laser beam concentrated onto a small spot with high intensity so that both high resolution and a high S/N ratio can be obtained. This equipment has already been delivered to the broadcasting station and are being used to create HDTV programs using 35mm films.
