Abstract: PROBLEM TO BE SOLVED: To correct the surface defect of a print in a reflection scanning system by including elements for discriminating the influence of each surface defect on an infrared optical image, and for multiplying the influence of the surface defect by the function of the size of visible lights, and for generating a product, and for removing a product from the visible optical image, in a computer device. SOLUTION: A computer device includes elements for discriminating the influence of each surface defect on an infrared optical image, and for multiplying the influence of the surface defect by the function of the size of visible lights, and for generating a product, and for removing a product from the visible optical image. For example, an attenuation infrared conversion block 742 is generated by multiplying the full elements of an infrared conversion block 712 by a multiplexer 740 based on a gain calculated by a function block 730. Then, the attenuation infrared conversion block 742 is subtracted from an image conversion block 710 by a subtracter 744 by each element, and a corrected image conversion block 746 is generated. Finally, inversion is applied to the corrected image conversion block 746, and a corrected image block 758 is formed.

Abstract: Recovering the dye image on film in electronic film development following a latent holding stage obviates the problem common in prior art electronic film development of film image destruction. Recovery of the image is accomplished using a developing agent containing couplers to form a dye image. These dyes do not affect the infrared scans of the image. Upon complete development of the dye image, further dye formation is halted by the application of a coupler blocking agent, while silver development and electronic scanning may continue or halt. After halting dye formation, the film is stable for an arbitrary time in a latent stage and may be dried and stored. Following this latent stage, silver is removed from the film with a bleach-fix leaving a conventionally usable film image.

Abstract: In luminance priority multilayer color film, one of the layers substantially matches the luminance sensitivity of the human eye. This luminance layer distinguishes from prior art color films that have a blue, a green, and a red sensitive layer. This luminance layer has the priority front position to sense light before being diffused and attenuated by other layers, giving the luminance record enhanced speed and clarity compared to prior art blue-priority color film. In another embodiment, a layered CCD sensor has a top silicon layer that is sensitive to all colors, followed by a yellow filter, a second silicon layer responsive to green and red light only because of the yellow filter, a cyan filter, and a bottom silicon layer receiving only green light. An image from a luminance-priority color sensor inputs to a color space conversion to recover full color. In the preferred embodiment, a luminance layer on top maps to a luminance "Y" value, and underlying color sensitive layers are used in conjunction with the luminance to derive the "U" and "V" chrominance vectors of YUV color space.

Abstract: Surface defect correction technology for photographic images requires an infrared scan along with a conventional color scan. In the present invention, the additional infrared scan needed for surface defect correction is obtained by adding a line of sensors specific to infrared light to a conventional multilinear color sensor array. The invention teaches a practical mode of distinguishing infrared light using a dichroic prism placed over the sensor. This mode has the additional advantage of placing the infrared-specific sensor line in a displaced focus plane to match conventional lenses. Adding a sensor line to a conventional trilinear sensor array requires a quadrilinear array topology. In addition to the direct quadrilinear topology, the invention teaches a method of obtaining full color image information with only two linear sensor lines by interstitially mixing red and blue sensors on a single sensor line, which, in conjunction with the additional infrared line, results in a conventional trilinear sensor topology with a different filter arrangement.

Abstract: In electronic film development, a film is scanned, using light, multiple times during development. The light is reflected from an emulsion containing milky undeveloped silver halide embedded with developing grains. The undeveloped halide layer has a finite depth over which photons from a light source scatter backward. This depth is within the range of the coherency length of infrared sources commonly used in electronic film development, causing coherency speckle noise in the scanned image. A prescan made after the emulsion swells, but before the silver grains develop, normalizes subsequent scans, pixel by pixel, to cancel coherency speckle and other defects.

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.
