A method for acquiring the image of an object, such as a part of a hand (F), that is rolled on a detection surface (12). The method comprises acquiring the image on an area (140) on which the object is rolled that is located within the detection surface (12). The method comprises: —detecting (100) an initial position (P) of the object (F) positioned on the detection surface (12); and —locating (102) the rolling area (140) within the detection surface (12) as a function of the initial position (P) in which the object (F) has been positioned on the detection surface (12). |
