Abstract:
A device for recording information by means of imaging with the aid of at least one light-sensitive sensor with a two-dimensional sensor surface, characterized in that:the device has: an adjustable lens means providing a plurality of lens positions; a first mode, in which a plurality of images of a surface are recorded by the sensor through the adjustable lens means at a first focus position which provides projections of images of the surface onto the sensor when the device is directly adjacent the surface more accurately than at a second focus position, each image of the plurality of images containing content which partially overlaps content of another image of the plurality of images, such that the overlapping contents of the images are utilized by the device to put together the images into a composite image; and a second mode, in which at least one image is recorded by the sensor of a field of vision through the adjustable lens means at the second focus position which provides projections of the image of the field of vision onto the sensor when the device is not positioned directly adjacent the surface more accurately than at the first focus position, and such that the first focus position and the second focus position are different.
