Abstract: Electronic camera filters comprise an electronic display configured for use with a camera system to provide different levels of image filtering, as a neutral density filter, for passage to a camera. The electronic display is programmable so that it may be calibrated to provide different desired filter levels associated with different settings of a camera lens iris, focus, zoom, or light meter measurement. The electronic display may be calibrated manually or by calibration information stored or otherwise downloaded into electronic display memory. The ability to program and calibrate the filter level setting enables the electronic display to be operated in synchrony with the camera lens iris, focus, zoom, or light meter it is calibrated with to provide a desired combined or synergistic optical characteristic. The electronic display may be controlled to provide synchronized operation by the same controller used to control the camera lens iris, focus, and/or or zoom.

Abstract: A digital mastering system for processing digital image signals originating from scanned motion picture film includes a film scanner for scanning motion picture film and generating a stream of digital image signals corresponding to motion picture images, a color grading channel that pre-visualizes a certain “look” that can be applied to the digital image signals and a digital rendering channel that renders the digital image signals pre-visualized for a certain “look” into a digital master. The “look” includes the appearances produced by either a standard motion picture print film and/or adjustments applied to a standard appearance to obtain a creative effect. The color grading channel includes a parameter generator for storing parameters for a plurality of “looks”, a digital color grading processor for applying one or more selected parameters to impart a pre-visualized “look” to the digital image signals and a display device capable of reproducing the color graded signals.

Abstract: A method for processing a sequence of digital image signals in order to match the appearance of a particular display medium, such as a motion picture print film, includes the steps of (a) converting the digital image signals into signal values in an analytical dye amount space where the signal values are proportional to a dye set corresponding to the particular medium; and (b) converting the signal values in analytical dye amount space into output values suitable for a display device, such as a digital projector. Moreover, the signal values in analytical dye amount space may be corrected for viewing conditions, such as printing flare, gamma, contrast ratio or neutrality.

Abstract: Dye imbibition printing blanks are disclosed comprising a support bearing a layer comprising a cationic mordant, a hydrophilic colloid and a plasticizer polymer, wherein the plasticizer polymer is a latex polymer having a glass transition temperature below about 30.degree. C. comprising from about 2 to 20 wt % of units having a quaternary ammonium group. In a preferred embodiment, the latex polymer comprises a vinyl co-polymer addition product of from about 50 to 98 weight percent of acrylic or methacrylic ester units, 0 to 48 weight percent of vinyl benzene units and 2 to 20 weight percent of the quaternary ammonium group containing unit. This latex provides a dye imbibition printing blank substantially free of haze and brittleness.

Abstract: A process for exposing dye imbibition printing matrix films is disclosed comprising imagewise exposing a matrix film comprising a visible light sensitive silver halide emulsion containing colloid layer on a support to blue, green or red light, wherein the visible light sensitive emulsion is also sensitive to UV light and the toe contrast of the imaged matrix film is controlled by (i) incorporating a UV absorber in the colloid layer of the matrix film, and (ii) flash exposing the matrix film with UV light in the substantial absence of light having a wavelength above 410 nm, wherein the UV absorber provides sufficiently low absorption above 410 nm such that it does not substantially alter the effective photographic speed of the matrix film during the imagewise exposure or the mid scale contrast of the imaged matrix film, and sufficiently high absorption to the UV light to decrease the resulting toe contrast of the imaged matrix film.

Abstract: There is described a system and method for reproducing an original record using a narrow band filter, such as a dichroic filter, to modify the contrast of the reproduction without modifying the color balance or the wavelength peak of sub-reocrds. The system is particularly useful in reproducing motion picture records where a multiplicity of additive lamp houses can be employed. The system reduces variations in contrast and color reproduction among different additive lamp houses.

Abstract: There is described a system and method for reproducing an original record using a narrow band filter, such as a dichroic filter, to modify the contrast of the reproduction without modifying the color balance or the wavelength peak of sub-records. The system is particularly useful in reproducing motion picture records using subtractive lamp houses so as to have their contrast and color reproduction match records generated using additive lamp houses.
