Abstract:

A method of placing a two-dimensional barcode symbol on a photographic element, the barcode symbol comprising collections of modules arranged in a regular array with a plurality of defined orientation directions, the photographic element exhibiting linear defects in a predominant direction and having a maximum width, includes the step of orienting the barcode symbol so that each defined orientation direction is rotated relative to the predominant direction sufficient so that no single collection of modules aligned in a defined orientation direction is completely obscured by the defect.

International Classification:

G06K019/06

US Classification:

235490, 235494

Abstract:

A method of locating a reference calibration patch on a photographic element, that includes the steps of: exposing the photographic element to form a latent image of a reference calibration target having a two dimensional barcode symbol with a finder feature and a reference calibration patch having a known spatial relation to the finder feature of the two-dimensional barcode symbol; processing the photographic element to form a density image from the latent image; scanning the density image to produce a digital image; locating the finder feature of the two-dimensional barcode symbol in the digital image; and locating the reference calibration patch relative to the finder feature in the digital image.

Abstract:

A method of calibrating digital images having pixels with pixel values includes the steps of: exposing a photographic element to form a latent image of a reference calibration target including a plurality of reference calibration patches; exposing the photographic element to form a latent image of a scene; processing the photographic element to form developed images from the latent images on the photographic element; scanning the developed images to produce digital images; measuring the pixel values of the digital image of the reference calibration target to produce a measured value for each of the reference calibration patches; obtaining an aim value and adjustment data corresponding to each reference calibration patch; generating image calibration corrections using the measured values, the aim values, and the adjustment data; and applying the image calibration corrections to the digital image of the scene.

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G06K 9/00

US Classification:

382141, 358448

Abstract:

A method of locating a linear defect on a photographic element, the element having a useful imaging width and the defect aligned with length of the element, includes the steps of: exposing a region of the element to create a latent image which is substantially uniform across the useful imaging width of the element; developing the latent image to produce a density signal; sampling the density signal with a photometric device; and analyzing the sampled density data for the presence of significant deviations aligned with the length of the element to locate the defect.

International Classification:

H04N 7/12

US Classification:

37524018

Abstract:

A method for transforming an image expressed in terms of a first image encoding to a second image encoding, includes converting a set of original scene exposure-factor values into corresponding first and second image encoding values. A transform is then derived between the first image encoding values and the second image encoding values. The transform is then applied to an image encoded in said first image encoding. Examples of different encoding that can be transformed include Rec. 709, sRGB and other known image encoding standards. A system for performing such transformations as well as an electronic device that is capable of performing such transformations are also disclosed.

International Classification:

H04N 5/14

US Classification:

348576, 348E05062

Abstract:

A video signal includes a plurality of frames of image data. A single frame of image data or multiple frames of image data, one or more reduced resolution frames, or a portion or portions of one or more frames or reduced resolution frames can be analyzed to determine initial statistics. One or more correction operations are then performed on the initial statistics to generate initial correction values. The one or more correction operations include a balance correction operation, a flare correction operation, and a tonal correction operation. After the initial correction values are determined, a temporal filter is applied to the initial correction values to generate final correction values. Optimized image data is then generated by applying the final correction values to image data in one or more frames.

International Classification:

G09G 5/10

US Classification:

345690

Abstract:

A method for generating a target display characteristic for a non-CRT display device includes establishing a sequence of luminance-factor values corresponding to original-scene neutrals. The luminance-factor values are converted to corresponding Rec. 709 signal values. The luminance-factor values are then mapped according to a desired system tone reproduction characteristic to corresponding luminous intensity values to be reproduced by the non-CRT television display device. The target display characteristic is generated by relating the corresponding Rec. 709 signal values to corresponding luminous intensity values.
