  • Patent number: 7068838
    Abstract: A system and method for automatically adjusting color parameters during a film-to-digital transfer. An operator uses standard telecine equipment to preview scenes in order to determine a natural clustering of fields or scenes. Each cluster is processed separately. All the fields in a cluster are treated as one unit in the sense that color adjustments for the cluster are based on the cluster color histogram, which is computed by aggregating the colors from all pixels in the cluster. Constraints are specified for the cluster. Variables of a constraint may be automatically specified or determined by an operator based on observing sample frames from the cluster. In addition, the operator can nullify a constraint if desired. Within each cluster, the system adjusts red, green and blue intensities of the digitizing device, gains for each of these color channels, and other parameters. The system first determines which settings respect the constraints and then optimizes the solution.

The exposure-corrected images are then transformed with a non-linear function that renders the exposure-corrected images with a tone scale of the film reproduction system, and the tonescale-corrected images are transformed with a linear function that emulates a film color look provided by the film reproduction system.

  • Patent number: 6989864
    Abstract: An image recorded on a photo film is projected through an imaging lens onto an image sensor. In accordance with a selected mode, set values are read out from a data ROM and are applied to a band pass filter having programmable digital filters. Pixel signals from the image sensor are converted into evaluation signals that are correlative with spatial frequencies of the image, and are filtered through the band pass filter with the frequency band determined by the set values. The evaluation signals are integrated, and a peak value of integration values obtained at different focusing positions is determined to be an in-focus position.

  • Patent number: 6990251
    Abstract: A method, system, and software are disclosed for improving the quality of a signal. A signal is converted to a digital representation and then segregated into separate data sets based on one or more properties of the data sets. Data sets exhibiting relatively more information associated with a selected property are designated as shepherd artifacts, and data sets exhibiting relatively less information associated with a selected property are designated as sheep artifacts. A representative shepherd artifact is then used to guide a representative sheep artifact, resulting in a guided artifact with enhanced signal properties. This process may be repeated for other categories of signal properties. The resulting guided artifacts may then be combined to form a processed signal with one or more enhanced properties having increased quality. The present invention finds particular application in photography and digital film processing, whereby the illustrated method may be used to improve image quality.

  • Patent number: 6979834
    Abstract: An image can be read during main scanning under an optimized image reading condition even if dust is attached to a document such as a photographic film or the like, or if there are scratches. A scanner irradiates visible light and infrared light from a light source, and an image of the document is separated into infrared and visible components. These components are detected for pixels of the image by an image sensor. A controller, e.g., of the scanner recognizes defective pixels based on the infrared component. Furthermore, the controller corrects a visible component level in the defective pixel based on the infrared component level of the defective pixel and a reference level obtained where there is no defect, in order to create a histogram. The controller determines image reading conditions such as, for example, an exposure amount (exposure time) for use during main scanning and an LUT gradation conversion characteristic based on this histogram.

  • Patent number: 6919915
    Abstract: A system for managing information on a carrier, and an image reading apparatus, which enable easy resetting of correction data. When a film carrier is mounted in an image reading apparatus main body, a control section reads the identification number of the film carrier from an EEPROM, and determines whether the identification number corresponds to any of the identification numbers stored in a RAM. When correspondence is not found, it determines that the film carrier is mounted in the main body for the first time, and correction data is read from the EEPROM and stored in the RAM with the identification number. Instead of losing the correction data if the substrate is replaced, the correction data stored in the RAM is read from the control section and written into a new EEPROM, thereby enabling easy resetting of the correction data.

  • Patent number: 6891645
    Abstract: An image reading apparatus in which extended image reading time is prevented when high quality image data is obtained, which image data is corrected by invisible light such as infrared light which is transmitted through an original. In a CCD scanner, visible light emitted from a light source is irradiated onto a photographic film. Infrared light emitted from the light source is reduced by an IR light reducing filter to be irradiated onto the photographic film. Visible light which has been transmitted through the photographic film is irradiated on a linear CCD by a lens unit, and the infrared light is reflected by a dichroic mirror to be irradiated on the linear CCD. Accordingly, the reading of invisible light can be effected at the same time that the reading of visible light is effected. It is therefore possible to prevent image reading time from becoming long due to the time required for the receiving of invisible light.

  • Patent number: 6891562
    Abstract: 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.
