Abstract:

A portable and economical telecine machine for rapidly converting images recorded on motion picture film to electronically available and manipulable video signals with extremely high frame accuracy and temporal correspondence. On a commercially-available flatbed editing table, motion picture film passes through a light-tight enclosure surrounding a strobe, the film, a mirror, and a video camera. When the film is centered between the strobe and the camera, the strobe flashes to optically transmit the film image to the video camera. The film is then advanced exactly one single film frame to record the next image. In this way, film images are recorded frame by frame by a video camera, converting the film images into video signals. Passage of the film is monitored by a film sprocket coupled to a bi-phase encoder. When the image is optically transmitted to the camera, it is recorded in the two next available video fields by the video camera.
