Filed:

Mar 14, 2001

Appl. No.:

09/808285

Inventors:

Wayne E. Prentice - Honeoye Falls NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G06K 900

US Classification:

382167

Abstract:

A method and structure for developing a photographic image from a camera, filtering the image, and developing the image. Filtering of an image entails separating the image into a luminance channel and chrominance channels, alternating the luminance channel by saturation and hue to produce the altered luminance channel and recombining the chrominance channels and the altered luminance channel. The hue controls the color of filtering and the saturation controls the strength of the filtering. Prior to separating and converting the linear exposure is converted to a logarithmic space. This conversion of linear exposure to logarithmic space allows the luminances channel to be altered independently from the chrominance channels. The alteration creates a filtered RGB to YCrCb matrix and applying the matrix to the logarithmic space produces a filtered logarithmic space. The invention recombines the YCrCb to RGB matrix to the filtered logarithmic space.

US Classification:

348243, 348241, 348246, 348251, 348257

Abstract:

Apparatus and method of correcting for dark current in a solid state image sensor, include capturing an image with the image sensor to produce a digital image having pixel values; correcting the pixel values with a dark level correction value; employing a control system to adjust the dark level correction value to drive the number of pixels having values lower than a predetermined value chosen to represent dark scene content to a predetermined range.

Abstract:

A method for producing an extended color gamut luminance-chrominance digital image from a captured digital image includes determining an estimate of the colors of the captured digital image of an original scene and further processing to produce an extended range output RGB image value including values outside the range that can be displayed on the output image display device, and producing an extended color gamut luminance-chrominance digital image by transforming the extended range output RGB image values to a luminance-chrominance representation.

International Classification:

H04N 5/225

US Classification:

3482071, 3482201

Abstract:

A dual mode digital imaging system has a still processing mode that produces an output image in a first color space and a motion processing mode that produces an output image in a second color space, in particular a first color space that is RGB and a second color space that is YUV. The digital imaging system includes a dual mode digital camera for use with a computer and a processing application for running on the computer, wherein the motion mode processing is relatively less complex than the still mode processing although at least one common control parameter is used to control both modes. The motion mode processing, which is performed using algorithms and software approaches designed to minimize processing time, nonetheless produces an entirely adequate relatively low resolution YUV image appropriate for applications such as videoconferencing. The still mode processing, on the other hand, uses more elaborate algorithms to optimize the image quality of a relatively high resolution RGB output image.

Abstract:

An electronic image capture device for capturing a color image, comprising an image sensor comprised of discrete light sensitive picture elements overlaid with a color filter array (CFA) pattern to produce sensor color image data corresponding to the CFA pattern; an A/D converter for producing uninterpolated digital CFA image data from the sensor color image data; a processor for processing the uninterpolated digital CFA image data to produce interpolated image data and for forming a TIFF image file containing both the uninterpolated CFA image data and the interpolated image data; and a memory for storing the TIFF image file.

Abstract:

A method for selectively optimizing a plurality of image characteristics for captured images, that includes modifying two or more one-dimensional image characteristic controls using a single loop position controller having one-dimensional control. The single loop position controller traverses useful ranges of each of the two or more one-dimensional image characteristic controls. Additionally, a user cycles through several combinations of the two or more one-dimensional image characteristic controls within a video loop; and has a means of selecting a desired image rendered according to the two or more one-dimensional image characteristic controls.
