Abstract
The electric pen device includes an optical system including a lens and an image sensor configured to convert an image signal of light that has passed through the optical system to an electrical signal. The electric pen device includes a control board configured to interact with an electronic device and a communication module configured to communicate by wire or wirelessly with the electronic device, so that an image or a picture taken by a camera is confirmed and an optical zoom is controlled from the external electronic device.
