Abstract
A method of sensing image data from a film fed by a pulse motor and associated components, whereby sensing is carried out at fixed intervals along the film, independently of whether the pulse motor is in an acceleration or deceleration period and without the use of a separate rotation sensor. Values are stored in advance representing constant feeding lengths of the film during periods of acceleration and deceleration. While the film is being transported during such periods, the stored values are read out in sequence and the sensor operated at time intervals defined by the stored values.
