  • Patent number: 6791721
    Abstract: An image reading device which has a reduced size and which can read images at high quality. LEDs, which are respective pluralities of light emitting diode elements that emit red, green, blue and infrared light, are disposed at an area CCD scanner. A frame image of a photographic film is successively read with light of each wavelength by emitting light from the LED elements. Pixels that are affected by a scratch or dust at the photographic film are detected by the infrared light. Red, green and blue image data for such pixels is corrected by means of interpolation or the like. Thus, images can be read at high quality. Furthermore, because the LEDs are used as a light source instead of a halogen lamp, less heat is emitted, the device is more compact, and cut filters and the like are not needed.

    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.

  • Patent number: 6650443
    Abstract: A scanner effectively uses the photoelectric conversion range of a CCD and can determine the individual gains of RGB color channels to adjust gray balance. In order to obtain the advantages, an electric-charge storage time of the CCD is set in such manner that the CCD is not saturated even when the illumination intensity of a lamp is maximized. In this arrangement, a CPU controls an inverter control circuit to change the illumination intensity of the lamp. The CCD is kept sufficiently far from the saturation region, and so the output level of the CCD changes linearly with respect to changes in the illumination intensity. In addition, since the CCD output level obtained when the storage time is set to be the same as that set at the time of scanning can be predicted, the illumination intensity of the lamp can be obtained by calculating an output level at which no saturation occurs in that situation.

    Abstract: A pattern analyzing portion analyzes a pattern of a detected repeat field and determines whether or not the pattern of the repeat field is continuous. An inverse pull-down controlling portion controls a memory to read video data in such a manner that the repeat field detected by a comparator is removed from input video data in a period that the pattern of the repeat field is continuous. The inverse pull-down controlling portion controls the memory to read video data in such a manner that a repeat field detected by the comparator is not removed from the input video data in a period that the pattern of the repeat field is discontinuous. In other words, an inverse 2:3 pull-down process is controlled corresponding to the continuity of a pattern of a repeat field. In addition, it is determined whether an input original material is a progressive-scanned video material or an interlace-scanned video material corresponding to the continuity of the pattern of the repetitive material.

  • Patent number: 6621521
    Abstract: An image recorded on 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 consisting of programmable digital filters. Pixel signals from the image sensor are converted into evaluation signals which 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: 6618547
    Abstract: A system for generating a digital representation of a video signal comprised of a sequence of video frames which each include two video fields of a duration such that the video plays at a first prespecified rate of frames per second. The sequence of video frames includes a prespecified number of redundant video fields. Redundant video fields in the video frame sequence are identified by a video processor, and the video frame sequence is digitized by an analog to digital convertor, excluding the identified redundant video fields. The digitized video frames are then compressed by a video compressor to generate a digital representation of the video signal which plays at a second prespecified rate of frames per second.

  • Patent number: 6583811
    Abstract: In a fine photo mode, a camera photographs a series of frames from the same scene upon one depression of a release button, and records data of correlation between the frames of the same scene in association with the series of frames. When a printer reads the correlation data, the printer composes a high definition image from image data of the series of frames, and make a print of the high definition image. A literal photo mode may be selected for a scene containing a literal image. The camera records data representative of the literal photo mode in association with the frame taken in the literal photo mode, so the printer processes image data to improve sharpness and resolution of the literal image of the frame, and makes a hard copy of the literal image from the processed image data.

  • Publication number: 20030081117
    Abstract: A method of transferring an image recorded on a photographic film to a digital signal, using a film scanning device that generates scan data representative of the digital signal, comprises the steps of calibrating the film scanning device in relation to printing densities and scanning the photographic film with the film scanning device to produce scan data that represents printing densities. Inasmuch as the digital signal is used to drive a film recorder that exposes an output film that is subsequently printed onto a target print material, the scan data represents printing densities which when written out to the film recorder will produce printing densities of the output film onto the target print material that are identical to the printing densities of the same photographic film optically transferred onto the target print material.
