Here, the second wireless module 14 is disposed in the accommodating chamber 2 and electrically connected to the control module 5.

The following specifically describes the working principle of implementing color adjustment by the user's rotation operation of the rotatable key on the stylus.

Firstly, when a user uses the touch control pen and needs to perform handwriting color toning, the color adjusting function is started through a first preset input of the user to the rotatable key 9 or a second preset input of the user to the electronic device, and the rotatable key 9 or the electronic device outputs a first indicating signal for indicating the start of the color adjusting function to the control module 5.

Finally, the image processing module 7 determines the target color displayed on the electronic device by the stylus according to the rotation signal, generates a second indication signal carrying the target color information, and outputs the second indication signal to the electronic device.

It should be noted that, in an alternative implementation manner, the surface of the rotatable key 9 has different textures, and the image processing module 7 may determine, according to the acquired image information of the rotatable key 9, rotation information corresponding to the rotatable key 9, that is, different rotation directions and rotation angles, by extracting texture features in the image information, where the corresponding textures of the surface of the rotatable key 9 are different.

Here, when the color adjustment function is turned on by a first preset input of the user to the rotatable key 9 or a second preset input of the user to the electronic device 100, a current handwriting color of the stylus pen is displayed through a preset color identifier a (e.g., UI icon) on an editing interface operable by the stylus pen, for example, a drawing interface, as shown in fig. 4. In the process of rotating the rotatable key 9 by the user, the color of the preset color identification can be changed continuously, so that the user can conveniently check the currently selected color.

If the user wants to select the wide color gamut, the following operations can be performed:

starting a color adjusting function through a first preset input of a user to the rotatable key 9 or a second preset input of the user to the electronic equipment, and displaying the current handwriting color of the touch pen through a preset color identifier on an operable editing interface of the touch pen; then, the user selects the colors of the major categories by rotating the rotatable key 9, and after the user selects the colors, the user determines the first major category of colors by clicking the rotatable key 9; and then, performing refined adjustment under the first large color by rotating the rotatable key 9 by the user, and after the user selects the color, determining the selected target color by clicking the rotatable key 9.

It is noted that a broad range of colors may include red, orange, yellow, green, cyan, blue, violet. Further refined colors are corresponded under these broad categories of colors. Thus, color adjustment of the light gamut can be achieved by the above operation.

Specifically, the rotatable key 9 is disposed at a middle position of the pen body 1 or at a preset position of the pen body 1 close to the touch portion 4.

In an optional implementation manner, the elastic key includes a circuit board 11, a mounting seat 12, and a deformation elastic sheet 13, where the deformation elastic sheet 13 is disposed on the circuit board 11 through the mounting seat 12.

It should be noted that the control module 5, the image acquisition module 6, the image processing module 7 and the light source 8 are all disposed on the circuit board 11.

Further, the circuit board 11 is provided with an electrical connection portion.

Under the condition that the rotating assembly is pressed by external force, the rotating assembly drives the deformation elastic sheet 13 to be electrically connected with the electric connection part; under the condition that the rotating assembly is free from external force, a first gap is formed between the deformation elastic sheet 13 and the electric connection part.

On the other hand, the rotating assembly is provided with a plurality of convex parts (not shown) at intervals in the rotating direction, and the deformable elastic sheet 13 is electrically connected with the electric connection part under the condition that the convex parts are abutted with the deformable elastic sheet 13; under the condition that the convex part is not in contact with the deformation elastic sheet 13, a first gap is formed between the deformation elastic sheet 13 and the electric connection part.
