Abstract
The invention concerns a flying spot telecine apparatus wherein the film is driven at constant speed with a film frame rate which is not exactly half the television field frequency, for example at 24 frames per second where the field frequency is 60 fields per second. To avoid registration problems only one scan of each film frame is made, preferably a sequential scan, and the video processing circuits comprise a storage arrangement into and from which picture information derived from the said one scan is stored and extracted in a desired sequence for producing the necessary number of fields for a complete television signal. To simplify the organisation of the storage arrangement, particularly where the vertical amplitude is adjustable to allow for different film formats, the apparatus comprises means for generating synchronising signals at the desired film frame rate, these signals then being used to synchronise not only the motion of the film but also the vertical deflection of the flying spot and the operation of the storage arrangement.
