International Classification:

G09G005/02

US Classification:

345589000

Abstract:

The present invention is directed to a system that produces a characterization target for an existing input/output device using fixed control values and dynamically created control values. The fixed control values are chosen from the existing device color space and provide a sample of the gamut of the device. Important colors are dynamically chosen from a number of different sources including user selections, device target measurements and visual neutrals, and dynamically converted into corresponding colorimetric values. An existing characterization associated with the existing device is used to dynamically convert the colorimetric values into the dynamic control values. The fixed and dynamic control values are used to generate the target. The color patches of the target can be arranged to reduce errors in target reproduction and to allow visual confirmation of the target. The target can then be output, measured and used to characterize the device.

International Classification:

G06K 1512

US Classification:

382276

Abstract:

A system is disclosed that uses input and output color space identifiers and other information about the transforms to automatically determine a size and a class of identity function composite tabular function. The identity function is constructed. The identity function is composed with input and output composite tabular functions to form a net composite tabular function. The identity function is selected based on the characteristics of the input and output spaces, color space, and transform shape. The size of the identity function is determined by the maximum size of the color space functions and the interval spacing that needs to be maintained for the net function.

Appl. No.:

Inventors:

George Boynton Pawle - North Reading MA

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G06F 1717

US Classification:

364723

Abstract:

An interpolation system that breaks a color transform interpolation function into several suboperations or subfunctions. The subfunctions produce intermediate function results. The intermediate results are stored in a cache as the function is evaluated. Cache management operations locate and assign a cache cell to the intermediate results. In a subsequent evaluation that requires the same intermediate results, the intermediate results are obtained from the cache. The cache look-up rapidly provides the intermediate results which are then used to complete the function evaluation.

International Classification:

H04N 156
H04N 160

US Classification:

358504

Abstract:

A system that combines a reference color image with a color move tracer image creating a combined image capable of being edited as desired by the operator and one which records the actual color edits made on the reference image. The tracer is a color grid that represents the domain of colors in a specified color space encoding. The grid is converted into a color edit transform table and the color edits within the color space on a higher resolution version of the reference image, or on other images, can be performed using a table look-up operation. The invention can also be used to capture effects transforms that modify the input/output and/or screen display of an image without necessarily modifying the original image.
