SYSTEM FOR ENHANCING A DIGITAL IMAGE

摘要

The present invention concerns a system for enhancing a digital image which comprises a detection device (1), provided for detecting objects within the image, and a processing device (2), provided for processing the image by subsets upon detection of an object within the subsets. The detection device (1) mainly comprises a circuit (12) for the detection of text objects within said image, and the processing device (2) comprises a circuit (28) for the determination of the parameters of the text objects that are detected, said determination consisting in applying for each subset local operations to an area within the subset, said local operations varying upon the content of the subset containing this processed area and upon the membership of said processed area to a text object. A refinement circuit (3) allows to perform final classical enhancement operations.
