Abstract

La invención se refiere a un procedimiento para obtener información de imagen, por ejemplo una información de una imagen relativa a la superficie de la palma de una mano, el lado de una mano, los cuatro dedos extendidos (2) o el pulgar extendido, para producir una imagen de alta calidad. La superficie a grabar se coloca sobre una superficie de exploración (11) que produce una imagen de la estructura superficial usando una trayectoria de un rayo (13). De acuerdo con la invención, la superficie de exploración (11) tiene una relación de altura:anchura de B{sub,A}:H{sub,A}<1. La relación de altura:anchura de la imagen se altera durante la transmisión óptica desde la superficie de exploración (11) al convertidor optoelectrónico de imágenes (17). La altura se comprime y/o la anchura se extiende de manera que la imagen que se produce sobre la superficie de recepción (16) del convertidor de imágenes (17) esté ópticamente distorsionada, con una relación de altura:anchura de B{sub,E}:H{sub,E}>1. Estose corrige subsecuentemente mediante una operación aritmética. La invención también se refiere a un dispositivo para llevar a cabo este procedimiento.
