Abstract: A stylus pen includes a pen body, an electromagnetic touch pen module which includes an electromagnetic pen head disposed in a top end of the pen body and a first circuit board connecting with the electromagnetic pen head, a camera module which includes a second circuit board, a camera lens embedded in a cavity of the top end of the pen body and a power button, a rechargeable battery pack disposed in the pen body to supply power for the electromagnetic touch pen module and the camera module, and a function button connected to the first and the second circuit boards to act as a right mouse button and a shutter button. The stylus pen switches working modes between the camera module and the electromagnetic touch pen module through powering on and off the power button.

Abstract: A method of capturing real-life colors is adapted for being achieved by a pen camera including a camera module which has a circuit board, a camera lens built in on the tip of a pen body, a shutter button and a power button. The method includes the steps of: actuating the power button to power on the camera module; pointing to an item directly with the camera lens, the item has the desired real-life color; actuating the shutter button to make the camera lens capture the item and be saved as a photo; transmitting the photo into a target console; utilizing an application processing software in the target console to extract the desired real-life color in the photo and then define the extracted color; renaming the defined color and being saved in the target console to make the defined color capable of being used in other painting or sketching operations.
