A method and system of capturing a three dimensional image of an object or scene and using the information obtained to produce a physical representation of the object or scene. The physical representation may be dynamic, for moving objects, or permanent.

Three dimensional images

A method of processing data from a digital image to enhance the neutral tonescale estimates a neutral offset, a neutral gain and a neutral gamma from the input data and uses these estimated values to transform the input image data.

Tone scale adjustment of digital images

A color film comprises a support layer, a layer formed of a color filter array having at least three spectrally distinguishable types of color element and an emulsion layer unit. The film further includes means for emitting or reflecting light which has been modulated by the filter array but not by the image pattern formed in the emulsion layer.

Color filter array film

A method of digital photofinishing comprising the steps of: producing a digital color image having colorimetric tristimulus values describing a color transparency media from a color image captured on color transparency photographic media; first transforming the digital color image having colorimetric tristimulus values describing color transparency media to a digital color image having colorimetric tristimulus values describing a reflection print; second transforming the digital color image having colorimetric tristimulus values describing a reflection print into digital code values representative of the color image for printing by a digital color printer using a combination of 1D and 3D look up tables; sharpening the transformed digital code values representative of the color image with a sharpening algorithm optimized to avoid unacceptable artifacts; and digitally printing the sharpened digital color image onto reflection media.

Method and means for producing high quality digital reflection prints from transparency images

A method of making a stereo image of a scene. The method includes capturing and digitizing a first image of the scene in a first image capture medium and capturing and digitizing a second image of the same scene but from a displaced position from which the first and second image was captured on a second different image capture medium. The method further includes producing visual images of the first and second captured digital images which, to a viewer, provides a stereo image of the scene.

Using two different capture media to make stereo images of a scene

A method of processing a sampled input image having pixels which can have missing information at pixel locations to reconstruct an output image therefrom, including providing a mask for the sampled image to identify valid pixel locations; interpolating by convolution with at least one finite impulse response (FIR) filter(s) applied to the information at valid pixel locations to produce reconstructed information for non-valid pixel locations; and adaptively normalizing the reconstructed information for the non-valid pixel locations produced by applying the FIR filter(s) to the mask so that the valid pixels and the reconstructed information at non-valid pixel locations provide a reconstructed image.

Reconstructing missing pixel information to provide a full output image

A digital image with improved performance characteristics is formed by producing a photographic image of a scene; producing a digitized electronic image of the same scene; scanning the photographic image to produce a digitized photographic image of a scene; and combining and processing the digitized electronic image and the digitized photographic image to produce another digitized image with improved performance characteristics.

Apparatus and method of producing digital image with improved

A method of producing a digital image with improved performance characteristics including capturing at least two photographic film images of a scene and digitizing the at least two photographic film images of a scene. The method further includes combining and processing the at least two digitized photographic film images to produce another digital image with improved performance characteristics.

Method of producing digital image with improved performance

In digital image processing, it is often necessary to alter the image by performing a zoom operation thereon. Such an operation is carried out with the use of a spatial interpolation unit. Described herein is a spatial interpolation unit which comprises a discrete set of filters for which at least some of the cut-off frequencies are logarithmically spaced.

Digital signal processing

A median filter is modified for temporal suppression of image grain in a time-varying sequence of images. Successive sets of samples are produced by operation of a sample producer (20), each set including a current sample, a sample delayed by a framestore (50), and a sample derived from a recursive component generator (60). A median selector (80) operates upon each set to select the median sample value. Either the median value or the current sample is selected for the filter output, dependent upon an interframe magnitude generated by an adaptive component generator (30). Evaluation of interframe magnitude minimizes artifacts in the reproduction of picture information that is temporarily impulsive, while including the recursive component in the median sample set increases the level of grain suppression.

Adaptive, hybrid median filter for temporal noise suppression

A bandpass enhancement filter has a pass-band that tracks changes in spatial frequency due to the use of a zooming process upon a digital image signal. The primary pass-band of the enhancement filter is derived from a combination of a plurality of secondary bandpass filter sections, each having a different frequency response and each responsive to a gain adjustment. A control signal reflecting a particular zoom ratio is used in the adjustment of the gain applied to the filter sections, thereby proportioning the output of each filter section so that the combined output tracks the zooming process.
