Method for processing an imprint image

A device for processing at least one image of an imprint of an individual, comprising:

• an exposure window one face of which is designed to receive the said imprint;
• a first detection means designed to detect an approach of the imprint to the exposure window;
• a contactless means for capturing designed to capture at least one contactless image of the imprint present in the space upstream of the said face and that is not yet in contact therewith, wherein the at least one contactless image is captured immediately after said approach of the imprint to the exposure window is detected by the first detection means;
• a second detection means designed to detect the putting of the imprint in contact with the exposure window, immediately after capturing of the at least one contactless image of the imprint by the contactless means for capturing;
• a means for capturing with contact designed to capture at least one image with contact of the imprint immediately after it is put in contact with the exposure window;
• and
• a standardization means designed to standardize the at least one contactless image according to at least one of the images with contact by analysis of the at least one of the 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.
