A device for recording hand-written information in the form of characters, symbols, graphs, drawings, calligraphy and similar hand-written information defined by a hand movement, comprises recording means () which are adapted to be moved by a hand which carries out the hand movement and to record a plurality of images with partially overlapping contents while the recording means are being moved. The device further comprises image-processing means () which are adapted to determine the relative position of the images with the aid of the partially overlapping contents for providing a description in digital format of how the unit has been moved and, in this way, a digital representation of the hand-written representation. A method of recording hand-written information is also disclosed.
