Abstract

The present invention concerns a method and an apparatus for recognizing text in an image, wherein said image represents a subject (4), comprising the steps of: (a) processing a digital image (3) to obtain a first modified image (3A); (b) performing Optical Character Recognition (OCR) on said first modified image (3A) to determine at least one text-containing region (3B) within said modified image (3A) and associating a first reliability value (C1) to said first region (3B); (c) converting said recognized text into a first voice signal (S1); wherein said processing step (a) comprises the additional step of automatic correction of the graphic parameters of said image (3), said graphic parameters including brightness, contrast, saturation and/or equivalent color spaces.
