1. Method of processing at least one image of an imprint of an individual by a processing device ( 200 ) comprising an exposure window ( 202 ) one face of which is designed to receive the said imprint, the method comprising: a step ( 104 ) 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, a step ( 106 ) of detecting the contact of the said imprint with the exposure window ( 202 ), a step ( 108 ) of capture with contact of at least one image with contact of the imprint after it is put in contact with the exposure window ( 202 ), and a step ( 110 ) of standardisation of at least one of the contactless images in proportions identical to those of one of the images with contact by analysis of at least one of the contactless images and at least one of the images with contact.
