Claim One:
1. Method for extracting raw data from an image resulting from a camera shot, said method comprising: determining, for each point located by column C and line L of the image, a value V 0 [C, L] consisting of a combination of colour components of the image, calculating, for each point of the image, a threshold value V Back. (C, L) calculating for each point of the image, the difference D[C, L] D[C, L]=V Back. −V 0 [C, L] (dark data/bright background) or V 0 [C, L]−V Back. (bright data/dark background) calculating a threshold value V S consisting of a noise contextual datum used for correcting the extracted raw data D[C, L], from at least one contrast histogram and/or from the probability q that a regional maximum of the raw data contains noise correcting the raw data D[D, L] by means of the noise contextual datum V S , resulting in the extracted data D*[C, L] calculating, for each point of the image, a corrected value I*[C, L] taking into account the corrected raw datum D*[C, L] optionally presenting the extracted data or the image which contains them under a desired angle.
