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.

First claim

What is claimed is:

1. An electric pen device having an optical zooming function and mounted and used with an electronic device, the electric pen device comprising:
an optical system configured to perform an optical zoom and comprising at least one lens;
an image sensor configured to convert an image signal of light that has passed through the optical system to an electrical signal;
a housing which houses the optical system and the image sensor;
a control key which is disposed inside the housing or on a surface of the housing and configured to control the optical zoom of the optical system; and
a controller comprising a communication interface configured to communicate with the electronic device,
wherein the controller is configured to confirm, via the communication interface, images or pictures taken by the optical system and the image sensor and to control the optical zoom, by the electronic device which is a device external to the electric pen device.

2. The electric pen device of claim 1 , wherein the optical system and the image sensor are disposed in a first region of the electric pen device, and
a light entering region through which an external light enters the electric pen device is formed on an end portion of the first region.

3. The electric pen device of claim 1 , wherein the controller is disposed in a second region of the electric pen device.

4. The electric pen device of claim 3 , wherein the controller further comprises a control board configured to detect a location and a pressure of the electric pen device.

5. The electric pen device of claim 1 , further comprising a battery mounted in the electric pen device.

6. The electric pen device of claim 5 , wherein the electric pen device is configured to wirelessly communicate with the electronic device.

7. The electric pen device of claim 1 , wherein the optical system further comprises an optical path conversion unit which is disposed on an end portion of the optical system and is configured to change an optical path of an external light that enters the electric pen device.

8. The electric pen device of claim 7 , wherein the optical path conversion unit comprises a prism or a mirror.

9. The electric pen device of claim 1 , wherein the electronic device comprises a smart phone, a notebook, or a monitor.

10. The electric pen device of claim 1 , wherein the at least one lens is one of a plurality of lenses which are disposed one after another on a path of light between a light entering region and the image sensor.
