Abstract: A method for edge mapping images for use in image processing. Edge mapping includes identifying base and non-base color components. A search window in the base color component is opened (44) and the non-base color components are compared with the base component picture. The number of matched or unmatched edge points is then calculated (46). The best match can then be determined through testing (50) or manual selection (48).

Abstract: A single pass scanner having a trilinear array, a source of white light, filters of the three primary colors and a separate source of infrared light is used in various methods of removing medium-based defects from a scanned film image. The method generates an infrared channel in addition to the common visible channels by covering the parallel rows of sensors in the trilinear array respectively with a red, green and blue filter to create the three color channels. Normally, each of the three color filters also passes infrared light, which is removed by filters external to the sensors. In a specific embodiment, interstitial in time between two visible light scans, the sensor is exposed to infrared light for a single scan. As the trilinear array sweeps across an image in time and spatial synchronization with the exposing lights, at least two visible channels and an infrared channel are generated.

Abstract: An illumination system for a film scanner is disclosed which comprises a light source and optics for providing a line of light on a film. Light transmitted through the film is imaged onto photosensor elements such as CCD arrays. In order to obtain a high quality electronic image from various types of film, an integrating cylinder is used to provide a line of diffuse light on the film, and light delivered to the integrating cylinder is controlled in accordance with the particular type of film being scanned and the operating conditions of the apparatus.

Abstract: A method for decoding National Television System Committee (NTSC) signals which exploits redundancies in film-to-NTSC transcoding, known as '3-2 pull-down'. The decoding method estimates luma (Y) and chroma (C). The '3-2 pull-down' structure assigns three NTSC fields to one frame of a film frame pair, and two NTSC fields to the other film frame. Luma and chroma in different film frames are separated using different methods, and the separated signals are better than the separated signals achieved using conventional one dimensional and two dimensional NTSC decoding methods. The new method for separating luma and chroma from composite NTSC signals can be combined with an interlace-to-progressive method (22), which converts the decoded 3-2 NTSC signals (20) to two film frames, and an upconversion procedure (24), to yield improved image quality.

Abstract: A telecine scanner is selectively conformed to evaluate the dye densities characteristic of either negative or print film. The film (10) is interposed in a light path (12) between a light source (14) and a pickup stage (16) that develops a plurality of color output signals from the light passing through the film. Color channel filters (38, 40, 42) included in the pickup stage have spectral passbands in the respective colors that are broad enough to include the spectral dye densities of both negative and print materials. The scanner sensitivity is further limited to a particular film material by inserting an appropriate shaping filter set (44, 45) into the light path, preferably between the light source and the film, for conforming the peak sensitivity of at least one of the passbands to the peak spectral density of the corresponding dye of the particular film material.

Abstract: This invention relates to a method for increasing the range of values representing a color image which exhibit a linear response. To increase the linear range, look-up tables are formed which straighten the toe and shoulder regions of film's three density vs log exposure curves up to a prescribed limit. The values of the minimum densities for the piece of film containing the image are determined. The representative values of the image are then aligned with the input values of the look-up tables by a relative shift of the image values and the table values so that the minimum density values of the image equal the minimum density in the look-up tables. The color density image is then processed through the look-up tables to increase its linear range.

Abstract: A colour scanner (10) scans an original (11) with a spot of light and image modulated light is passed to a beam splitter (22, 29) for splitting the modulated light into component wavelength ranges. The component ranges are passed to respective detecting devices (12, 13, 14). To overcome defects in an original such as scratches or dust which cause light scattering, internally reflective containing and directing means (30, 19, 20, 21, 28) define the optical path to the beam splitter so that scattered light from the original is passed thereto.
