Abstract
A film scanner is disclosed including a linear image sensor moveable to a scan position for scanning lines of image frames of an elongated film having a series of edge perforations including a reference perforation for each image frame. The film scanner further includes a rotating film gate for supporting the film in the scan position wherein the rotating film gate includes a rotatable encoder for producing an encoder signal indicative of the position of the film as it passes through the rotating film gate, a film transport mechanism for advancing the film through the rotating gate, a perforation detector mounted relative to the scan line of the image frame located at the scan position for producing hop and weave signals in response to detection of the reference perforation, a sensor transport assembly mounted relative to the rotating film gate and moveable in a weave direction, and including means for mounting the image sensor for movement in the weave direction, and signal processing means responsive to the weave signal for causing the sensor transport assembly to move the linear image sensor in the weave direction to align the linear image sensor with the image frame associated with the reference perforation, and further including means responsive to the hop signal and the encoder signal for producing a start scan signal.
