Data processing device for intelligent pen

Abstract

The invention relates to a data processing device for an intelligent pen. The device comprises a pressure sensor used for inducting pressure generated by writing and generating pressure detection data, a main chip used for receiving the pressure detection data and outputting an image acquisition control signal according to the pressure detection data, an image sensor used for receiving the image acquisition control signal, acquiring an image of a lattice coding pattern on the medium through which a pen tip passes and generating lattice coding image data, a decoding chip used for decoding the lattice coding information, generating the lattice coordinate information and sending the lattice coordinate information to the main chip, a communication module used for receiving the handwriting information and sending the handwriting information to an external device, and a printed circuit board which is provided with the main chip and the decoding chip and further provided with a pressure sensor interface socket, a communication module interface socket and an image sensor interface socket, wherein the lattice coding information is extracted by the main chip according to the lattice coding image data, and the handwriting information is generated by the main chip according to the pressure detection data, the time data and the lattice coordinate information at each time period.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data processing device for a smart pen. Background technique [0002] At present, people are becoming more and more accustomed to using computers and smart phones to enter information, but due to factors such as the limitation of application scenarios or the preservation of original evidence, traditional writing with pen and paper cannot be replaced. [0003] Therefore, devices for recognizing and processing handwriting have a wide range of application markets, and the recognition of handwriting involves many data processing processes such as image acquisition, analysis, and transmission, resulting in the current smart pens. The experience is not good, and the structure is complicated, and the production cost is high. Contents of the invention [0004] The object of the present invention is to provide a data processing device for a smart pen, which can realize the el...
