Handwriting synchronizing device and method

The invention discloses a handwriting synchronizing device which is used for an electronic pen and electronic equipment. The electronic pen is used for writing on paper sheets with the consistent content as an electronic document in the electronic equipment. The electronic pen comprises a pen cover, a pen cartridge, a gyroscope, a first processing chip, a pressure sensor, a camera and a data transmission chip. The electronic equipment comprises a data receiving chip, a screen and a second processing chip. According to the handwriting synchronizing device, the relative starting point position and the follow-up point positions of one-time handwriting are obtained through a positioning module in the first processing chip, and a handwriting recognition module obtains handwriting parameters, integrates the handwriting parameters into data packets and transmits the data packets to the electronic equipment side; the starting point of the handwriting is judged through a starting point judging module in the second processing chip, then, the starting points and handwriting parameters are correspondingly stored through a storage, and finally the starting points and the handwriting parameters are processed by a display chip and displayed in a screen, so that handwriting on true paper sheets and handwriting synchronization are achieved at the same time. The invention further discloses a handwriting synchronizing method.
