A film correction system adjusts a relative position of film containing an area for information and a scanner of the film area. The system includes a scanner for scanning the film area at a film plane, A film drive moves the film along the film plane. A focused beam separate from the film area scanner scans a film edge in the film for determining a location of the film edge. A circuit is coupled to the focused beam scanner for changing a relative position of the film area scanner and the film area. The film edge scanner is a flying spot scanner, and the apparatus includes signal processors for processing the sprocket information. The system may be retrofit to an existing telecine apparatus. A separate coil may be used to provide deflection of a flying spot scanner used to scan the picture information on the film.

The present disclosure teaches a method and apparatus for use in stabilizing images. The invention operates to sense the position of the image to be stabilized, compare the position of the image to a reference to determine a displacement value responsive thereto and change a correction element located in the conveyance path of the image in response to the displacement value to cause a compensating displacement of the image.
A scanning module for scanning a document is provided. The scanning module comprises: a chassis; a light source on the chassis for emitting a light ray onto the document; a plurality of reflectors inside the chassis; a lens inside the chassis; an image sensing device inside the chassis, an image of the document being reflected by the plurality of reflectors and formed on the image sensing device, the image sensing device including a plurality of sensing cells; and a plurality of microlenses on the plurality of sensing cells, each of the plurality of microlenses having a top surface and a bottom surface, the top surface having a plurality of notches as an input window for changing an incident angle of the light ray, the bottom surface having a plurality of round curves as an output window for further focusing the light ray.
In a film scanner with an automatic focusing device in which the film images are shown line by line by means of an objective on at least one line sensor, with a still film the adjusting range of the objective is passed through according to a predefined program. The then developing video signals are evaluated for their high frequency component. The objective is adjusted to the maximum of the high frequency component.
A film image input system is disclosed which can use a film cartridge constructed in such a manner that it requires a small space for storing a developed still photo film and also can protect the film against dust and damage, and also which allows the film cartridge to be mounted into a cartridge mounting part very simply and positively. The film image input system 1 is arranged such that it reproduces the image of the developed still photo film 2 on a video monitor 18. The system uses a film cartridge 6 which comprises a cartridge main body having an outlet opening 7 for sending out the film 2 in the longitudinal direction thereof, a single spool which fixes one end of the film 2 in the longitudinal direction thereof and round which the whole length of the film 2 can be wound, and support means for supporting the spool in such a manner that it can be rotated in both directions. The film image input system includes film supply means 13 which is engageable with the spool of the film cartridge 6 to rotationally drive the spool in a direction to send out the film 2 from the cartridge main body and in a direction to rewind the film back into the cartridge main body. Due to this, the film image can be reproduced by one touch on the video monitor 18.
