摘要： A method of and apparatus for removing the effects of surface and near surface image (12) storage media (14) defects from a scanned image using an infrared record as a norming control. Each pixel in a visible channel of the scanned images is divided by the corresponding pixel in the associated infrared control channel after it has been altered in gain to match the degree of defect in the visible channel. By appropriately altering the gain prior to dividing the pixel information, imbalances between the visible and infrared records which would leave defect residue after the division are reduced or eliminated. To remove defect residue, a degree of nulling is established for each defect region based on the visible and infrared content in that region. In one embodiment, the articulation gain is multiplicatively applied to the logarithm of the visible and infrared records.

摘要： The invention relates to a device for scanning films using at least one sensor comprising discrete photosensitive elements. Said photosensitive elements of the sensor can be randomly addressed in order to read video signals. The device is provided with an assembly for addressing that is adapted to the reproduction of the film on the sensor. The film can thus be reproduced on the sensor in its full width. Groups of image elements, onto which the film frame, the perforations and optionally an optical or audio track are reproduced, are addressed and read separately.

摘要： An apparatus and method for configuring a standard definition raster scanner telecine allows the standard definition telecine to produce an output at a faster than standard definition frame rate, but with a lower than standard definition resolution. This is achieved by configuring the film transport to move film past a light sensor at a multiple of a standard definition frame rate, and scanning the film at the multiple of the standard definition frame rate but with a reduced resolution.

摘要： A chassis for mounting components in a photographic film scanning apparatus cabinet includes a planar base member, and bearing mounts integral with the base member. The mounts sized and configured to hold bearings against which an arcuate wear plate of a gate of the scanning apparatus registers. The gate is configured to move in a pendulum-like manner across the bearings, with an aperture in the planar member for rotatably accommodating a shaft of a drive system for moving the gate in the pendulum-like manner. Mounts integral with the planar base member are provided for holding an optical system of the scanning apparatus. A continuous integral rib is arranged on the rear surface of the planar member is tuned to a higher natural frequency than that of the scanning frequency for vibrationally isolating the planar base member from other components in the cabinet.

摘要： A film registration gate assembly (30) has a gate with focal positioning location for focal positioning of an image frame (84) of a strip film (35) with edge perforations (86,87). Undersized first and second pins (105,106) enter a pair of transversely aligned perforations of the film to register the image frame with the positioning location. An undersized third pin (117) enters a third perforation spaced along the film from the second pin and then pulls the film obliquely to a reference line (64) extending between the first and second pins to nest against the first and second pins the perforations thereat and register the image frame precisely at the aperture. A plate with a window registering with the image frame and aperture (34) clamps the film against the gate. The window, positioning location and image frame are of corresponding size and shape. The pins register the image frame precisely with the positioning location, and the plate maintains the image frame in precise focal position thereat.

摘要： Video signals representative of photographic images which are stored in a plurality of substantially equally dimensioned frames (12a) in horizontal and vertical positions are produced by picking up the images. A first signal indicative of a horizontal/vertical position and a top-bottom orientation of the photographic image stored in any of the frames (12a) is entered. The photographic image is rotated relatively in response to the first signal. For a vertically positioned image, a video signal is produced which is representative of the image a magnification of which is smaller than that of a horizontally positioned image. Such a procedure provides a video signal which represents an image in a non-inverted top-bottom orientation without essential part of the image omitted.
