Abstract
In a method for recording a selected sequence of characters with the aid of a pen, the latter is passed over the sequence of characters and a plurality of images, whose contents partially overlap, are recorded simultaneously with the aid of a light-sensitive sensor ( ) with a two-dimensional sensor surface. The recorded images are put together, horizontally as well as vertically, into an image. Subsequently, the characters in the composite image are identified and stored in the pen with the aid of a predetermined character code formal. The putting-together, the character identification, and the storing are carried out with the aid of a signal processing unit ( ). By the method and the pen compensation is obtained for different speeds of movement and different angles of rotation of the pen.
