A film scanner is disclosed including an image sensor moveable to a scan position for scanning 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 an intermittent film transport mechanism for moving an image frame to a scanning position, and a sensor transport assembly mounted relative to the intermittent film transport mechanism and moveable in hop and weave directions. The sensor transport assembly includes a structure for mounting the image sensor for movement in the hop and weave directions, a detector mounted relative to the image sensor for detecting the reference perforation and for producing hop and weave signals, and circuitry responsive to the hop and weave signals to move the sensor transport assembly in the hop and weave directions to align the detector over the reference perforation, so that the image sensor is aligned with the image frame so that the image frame can be scanned.
