    摘要： A lamp, a film guide, and a photosensitive detector are combined into an optical system contained in a portable device that generates electrical signals representing images recorded on motion picture film. The film guide has a surface proximate to the motion picture with an aperture therein through which light from the lamp passes to image the film on the photosensitive detector. A digital processor, which is electrically connected to the photosensitive detector processes an electronic signal output by the photosensitive detector. To provide compactness, the optical system has a folded path comprising three segments each separately mounted on a different surface. The first segment includes the lamp, the second includes the film guide, and the third includes the photosensitive detector. An optical detector positioned so as to receive light from the lamp enables adjusting the device when the device is moved to a location where the temperature and other environmental conditions change. This configuration also finds use when the device is located in an environment whose temperature remains consistently hot.

    摘要： An illumination subsystem, a film guide subsystem, and an imaging subsystem are combined to form an optical system for a film conversion device which projects an image recorded on film onto the at least one optical sensor. The illumination subsystem comprises a lamp. The film guide subsystem comprises a film guide wide enough to support film moving thereover and having an aperture that permits passage of light from the lamp through the film. The imaging subsystem comprises an imaging lens and an optical sensor situated so as to receive the light passing through the aperture and the film. The three subsystems together have an optical path that is folded substantially into the shape of a “U”. This folded arrangement is achieved by placing optical beam bending elements in the optical path of the film conversion device between the illumination subsystem and the film guide subsystem, and between the film guide subsystem and the imaging subsystem. This folded arrangement of the components of the optical system permits the components of the illumination subsystem and the imaging subsystem to be mounted back-to-back on the same support structure within the film-to-video module. Consequently, the optical system requires less space than is required without the folding of the optical path.
