Method for modification of non-image data in an image processing chain
First Claim
1. A method for modification of metadata in an image processing chain that includes the step of performing an image transformation that modifies a characteristic of a digital image to produce a transformed digital image, comprising the steps of:
- a) providing metadata corresponding to the characteristic of the digital image;
b) generating a metadata transformation related to the image transformation that modifies the metadata so that it accurately describes the modified characteristic of the transformed digital image;
c) applying the metadata transformation to the metadata to produce transformed metadata;
d) associating the transformed metadata with the transformed digital image;
e) providing a metadata sensitive image transformation; and
f) using the metadata sensitive image transformation and the transformed metadata to modify the transformed digital image to produce a further transformed digital image.

Abstract
A method for modification of metadata in an image processing chain is disclosed. The method comprises the steps of: providing metadata corresponding to characteristics of a specific digital image; generating a metadata transformation related to at least one specific image transformation; and modifying the metadata according to the specific image transformation. The method is implemented in an image reproduction system. The system has an imaging capture device for providing digital image data. The imaging capture device can be for example a film scanner, flat bed scanner, or digital camera. A memory device stores metadata associated with the captured digital image data. The image transformations are carried out by an image processing chain. In addition to that a metadata processing chain is implemented and connected to the image processing chain in cases where the image transformations are metadata sensitive.
