1. A method of processing at least one image of an imprint of an individual by a processing device comprising an exposure window one face of which is designed to receive the said imprint, the method comprising: a step of detection of an approach of the said imprint to the said exposure window; immediately after detecting the approach of the said imprint a step of capture of at least one contactless image of the imprint present in the space upstream of the said face and that is not yet in contact with it; immediately after capturing of the at least one contactless image of the imprint a step of detecting the contact of the said imprint with the exposure window; a step of capture with contact of at least one image with contact of the imprint immediately after it is put in contact with the exposure window; and a step of standardization of the at least one contactless image according to at least one of the images with contact by analysis of the at least one contactless image and the at least one image with contact, wherein the standardization includes resizing of the at least one contactless image in proportions identical to the at least one of the image with contact.
