A device for recording information by means of imaging with the aid of a light- sensitive sensor with a two-dimensional sensor surface is described. The device is adjustable between a first mode and a second mode. In the first mode, the imaging is effected by means of a plurality of images with partially overlapping contents. Each of the images depicts a small area on an information carrier and the images are put together into a composite image. In the second mode, the imaging is effected by means of at least one image of a larger area of the information carrier. The device has means for indicating the size of the imaging area.

La présente invention concerne un dispositif d'enregistrement d'informations par imagerie au moyen d'un capteur photosensible pourvu d'une surface de détection bidimensionnelle. Ce dispositif est réglable selon un premier et un second mode. Dans le premier mode, on utilise pour la formation d'images une pluralité d'images disposées de manière à ce que leur contenus se chevauchent partiellement. Chaque image représente une petite surface d'une porteuse d'informations, ces images étant réunies pour former une image composite. Dans le second mode, on utilise pour la formation d'images au moins une image représentant une plus grande surface de la porteuse d'informations. Ce dispositif comporte par ailleurs des moyens d'indication de la taille de la surface de formation d'images.
