An electronic pen is configured for transmitting coordinate data to an external terminal. The pen includes an image component (200) configured to generate a digital image of a region on a writing surface. Further, the pen includes a communication component (202) comprising an image analysis module (202b) configured to receive image data representative of said digital image and to transform the image data into coordinate data, and a transmitter module (202c) configured to transmit the coordinate data to the external terminal. The communication component (202) may be a standard communication circuit with spare processing capacity, in which the image analysis module (202b) is implemented by image analysis software loaded into a working memory and executed by a processor of the communication component (202). |
