Title:
PHOTOGRAPHIC ELEMENT FOR CALIBRATING DIGITAL IMAGE
Document Type and Number:
Japanese Patent JP2002156718
Kind Code:
A
Abstract:

To perform high quality calibration in a photographic element at photographic finishing, such as development.

This calibration method is composed of a step of exposing the photographic element to form the latent image of a reference calibration target including a plurality of reference calibration patches, a step of exposing the photographic element to form a latent image of a scene, a step of processing the photographic element to form developed images from the latent images on the photographic element, a step of scanning the developed images to produce digital images, a step of 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, a step of obtaining an target value and adjustment data corresponding to each reference calibration patch, a step of generating image calibration corrections using the measured values, the target values and the adjustment data and a step of applying the image calibration corrections to the digital image of the scene.
