Abstract:
The present invention relates to a method for directly converting visual images, such as motion picture film, to a digital format and recording stable archival film elements so that a digitally-recorded film master or other visual image can be accurately reproduced without the necessity of creating a digital intermediate.
Abstract:
One aspect of the invention is a method for locating an unexposed region of film. The method includes the step of illuminating film with a light source while the film has developing chemical applied thereto, the film comprising at least two edges along an x direction perpendicular to a y direction parallel to a surface of the film. The method also includes the step of identifying an unexposed region of the film as a region containing ones of a first plurality of columns of the film, the columns disposed generally in the y direction and captured using at least one sensor operable to capture light reflected from the film, and wherein a representative value for each of the ones of first plurality of columns exceeds a threshold.
Abstract:
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.
Abstract:
A photographic film scanner (305) for scanning a film strip containing a plurality of photographic images is disclosed. The film strip is advanced through the scanner and a digital image of the film strip is created. Individual images contained in the digital image of the film strip are located and displayed. The film strip is scanned at any of a variety of resolutions.
Abstract:
During electronic film development, an area of conventional photographic film is scanned several times using a single scanning station, and at each subsequent time this scanned area is advanced incrementally along the film with multiple levels of overlap with previous scans. The new image scanned at each new time is aligned to an accumulating image that has been extrapolated to the image at the new time, and then the new image is added to the accumulating image in parametric summations that allow an image to be interpolated to any time free of seams where the scans overlap. The invention further teaches a method of steering the alignment by warping the leading edge of the alignment, and a registration method of aligning multiple images that takes advantage of known fixed alignments between images.
Abstract:
A photographic film scanner (50) for scanning a film strip (56) containing a plurality of photographic images is disclosed. Previous scanners are slow and are limited to scanning one type of film using one resolution. With the disclosed scanner (50), the film strip (56) is quickly and continuously advanced through the scanner (50) and a digital image of the film strip (56) is created. Individual images contained in the digital image of the film strip are located and displayed. The scanner (50) accepts multiple types of film and can scan at variable resolutions.
Abstract:
PROBLEM TO BE SOLVED: To provide an imaging apparatus for more easily registering an object (e.g., a face) to be identified. SOLUTION: An imaging apparatus identifies a specific object registered as an identification object and includes an imaging means (140) and a display means (220) operable to display a screen for prompting a user to perform an operation concerning registration as the identification object when the object is captured by the imaging means.
