[0033] The present application discloses a method and a stylus pen for controlling a terminal device based on optical information. The method is not limited to the stylus pen described below. The relevant structure of the stylus pen of the present application is described as follows:

[0034] See also Figure 1 , Figure 2 and Figure 3 The first aspect of the present application discloses a pen tip assembly 10. The pen tip assembly 10 includes a refill assembly 4, a collecting component 1, a light guide component 2 and a diffuse reflection component 3.

[0035] The refill assembly 4 includes a refill 41 (also referred to as a pen tip or pen head) for touch control, which can at least realize the touch function. Its structure is not limited. For example, for a capacitive stylus pen, the refill assembly 4 includes a weak conductor and a pressure-sensitive element, and the refill 41 is a part of the weak conductor; for an electromagnetic stylus pen, the refill assembly 4 includes the refill 41 and a coil (not marked in the figure).

[0036] The collecting member 1 is penetrated by the pen core 41, so that the collecting member 1 can collect light in the area pointed by the pen core 41. The structure of the collecting member 1 is not limited as long as it can collect light. It is not limited to the structure described later, and can be a condenser in a prism or other shape.

[0037] The light guide 2 surrounds the refill assembly 4, and includes a light guide head end corresponding to the refill 41 and a light guide tail end away from the refill 41; the light guide head end is optically connected to the collecting member 1. The light guide head end is optically connected to the collecting member 1, and the optical connection means that the light collected by the collecting member 1 can be transmitted into the interior of the light guide 2. The light guide 2 is used to guide light so that the light can be transmitted from the collecting member 1 to the diffuse reflection member 3. Its structure is not limited as long as it can play the above-mentioned role. For example, it is not limited to a single component, and can be a part of the pen body shell 40 and the pen tip shell 5, as well as a part of the refill assembly to form a structure capable of guiding light. The light guide tail end encloses a receiving cavity 21.

[0038] The diffuse reflector 3 is located in the accommodating cavity 21. Light passes through the collecting component 1 and enters the light guide 2. It is transmitted to the accommodating cavity 21 through the light guide 2. The light is scattered toward the inside of the accommodating cavity 21 by the diffuse reflector 3, so that the light is received by the optical sensor 20. Figure 1 The propagation path of part of the light is shown in FIG. The diffuse reflection element 3 can be realized by a diffuse reflection layer.

[0039] As described above, since the collection member 1 is passed through the pen core 41 used for touch control and is optically connected to the front end of the light guide member, the collection member 1 is used to collect light in the area pointed by the pen core 41. In this way, there is no need to make a hole in the pen body to collect light, and the appearance of the stylus is beautiful. The user only needs to point the pen core 41 to the area to be collected. Compared with the structure in which the hole is set in the pen body to collect light, there is no need to adjust the stylus so that the light can be collected by the optical sensor through the hole. The collection is convenient, the stylus is easy to use, and the user experience is improved. In addition, by scattering the light into the accommodating cavity 21 through the diffuse reflection member 3, more light can be received by the optical sensor 20, improving the utilization rate of light and the sensitivity of the optical sensor 20.

[0040] In some embodiments, the nib assembly 10 includes a nib housing 5 , the nib housing 5 includes a housing end 51 for the pen core 41 to pass through, and the collecting member 1 includes a spherical surface 11 protruding from the housing end 51 .

[0041] As set above, since the collecting member 1 includes the spherical surface 11 protruding from the end portion 51 of the shell, more light can be collected, thereby effectively improving the focusing performance of the incident light of the pen tip and improving the effect of light incidence.

[0042] In some embodiments, the field of view angle corresponding to the spherical surface 11 is a, 75 degrees ≤ a ≤ 180 degrees. When a = 180 degrees, the spherical surface 11 or the collecting element 1 can be considered as a hemispherical condenser.

[0043] As set above, since 75 degrees ≤ a ≤ 180 degrees, more light can be collected, which can more effectively improve the focusing performance of the incident light from the pen tip and improve the effect of the incident light.

[0044] In some embodiments, see Figure 1 Combination Figure 2 The light guide element 2 is provided with a light guide cavity 22 , and the light guide cavity 22 is provided with a total reflection layer 23 . The total reflection layer 23 totally reflects the light from the collection element 1 .

[0045] As configured above, the total reflection layer 23 totally reflects the collected light to transmit it to the diffuse reflection element 3, thereby improving the light utilization rate, reducing the light loss, and preventing the interference of ambient stray light.

[0046] See also Figure 2 Combined with Figure 1 The light guide cavity 22 includes a first light guide cavity 221 and a second light guide cavity 222 located above the first light guide cavity 221. The side wall of the first light guide cavity 221 is inclined toward the outside of the pen core 41. The side wall of the second light guide cavity 222 extends along the length direction of the pen core 41 and is connected to the side wall of the first light guide cavity 221 at an obtuse angle. Figure 1 The obtuse angle is shown as b. Figure 2 Combined with Figure 1 In the embodiment of the present application, the side wall of the first light guide cavity 221 includes a first light guide cavity outer wall 2211 and a first light guide cavity inner wall 2212, and correspondingly, the side wall of the second light guide cavity 222 includes a second light guide cavity outer wall 2221 and a second light guide cavity inner wall 2222. Figure 1 The total reflection layer 23 includes a first coating layer 231 disposed on the side wall of the first light guiding cavity and a second coating layer 232 disposed on the side wall of the second light guiding cavity.

[0047] As described above, the side wall of the first light guide cavity 221 is inclined toward the outside of the pen core 41, and the side wall of the second light guide cavity 222 extends along the length direction of the pen core 41, and is connected to the side wall of the first light guide cavity 221 at an obtuse angle, so that light can be better transmitted in the light guide cavity 22 by total reflection, thereby improving light utilization, reducing light loss, and preventing interference from ambient stray light. In addition, the obtuse angle setting does not affect the appearance of the stylus, ensuring the beautiful appearance of the stylus.

[0048] In some embodiments, the obtuse angle is b, 120 degrees ≤ b < 180 degrees, for example, 120 degrees, 123 degrees, 125 degrees, 128 degrees, 130 degrees, 135 degrees, 138 degrees, 140 degrees, 143 degrees, 145 degrees, 148 degrees, 150 degrees, 153 degrees, 155 degrees, 160 degrees, 163 degrees, 165 degrees, 168 degrees, 170 degrees, 173 degrees, 175 degrees or 178 degrees, etc.

[0049] As described above, since 120 degrees ≤ b < 180 degrees, light can be better transmitted in the light guide cavity 22 by total reflection, improving light utilization, reducing light loss and preventing ambient stray light interference. In addition, the obtuse angle setting does not affect the appearance of the stylus, ensuring the beautiful appearance of the stylus.

[0050] In some embodiments, the length of the side wall of the first light guiding cavity 221 along the length direction of the pen core 41 is h1, 15mm≤h1≤20mm, for example, 15mm, 16mm, 17mm, 18mm, 19mm or 20mm.

[0051] As set above, since 15mm≤h1≤20mm, the light propagation path is shorter, the light loss is smaller, and the loss is reduced.

[0052] See also Figure 2 Combined with Figure 1 In some embodiments, the light of the diffuse reflector 3 is scattered toward the optical sensor 20, and the length of the optical sensor 20 along the length direction of the pen core 41 is h0. The second light guide cavity 222 includes a second light guide cavity outer side wall 2221 facing the optical sensor 20, and the length of the second light guide cavity outer side wall 2221 along the length direction of the pen core 41 is h2, and h2≥1.5h0.

[0053] As set above, since h2≥1.5h0, it is ensured that the optical sensor 20 can receive as much light as possible, thereby improving the utilization rate of light, reducing light loss, and reducing consumption.

[0054] See also Figure 1 Combined with Figure 2 The second aspect of the present application discloses a stylus. The stylus comprises any of the aforementioned pen tip components 10 and an optical sensor 20, wherein the optical sensor 20 is located in the accommodating cavity 21, receives light from the diffuse reflector 3, and converts the light signal into an electrical signal. Color parameters can be obtained through the electrical signal. The color parameters are stored in a memory. The memory can be a memory of the optical sensor 20 itself, or a memory independent of the optical sensor 20.

[0055] See also Figure 4In some embodiments, the optical sensor 20 has multiple, Figure 4 The main board 30 has multiple sub-control boards 301. Figure 4 3. The plurality of sub-control boards 301 form a regular prism. Each sub-control board 301 is provided with an optical sensor 20. Figure 4 and Figure 1 It can be seen from the combination that the diffuse reflection element 3 surrounds all the optical sensors 20 .

[0056] As configured above, since there are multiple optical sensors 20 and sub-control boards 301, and the diffuse reflector 3 surrounds all the optical sensors 20, more light can be received, further improving the utilization rate of light, with less light loss and reduced consumption.

[0057] In some embodiments, see Figure 1 The main board 30 and the optical sensor 20 are both one. The optical sensor 20 is disposed on the main board 30 and faces the diffuse reflection member 3 .

[0058] See also Figure 5 In a third aspect, the present application discloses a data processing method. The data processing method can be applied to the stylus to send a color result to an electronic device. The electronic device can be a mobile phone, a computer, a digital broadcast terminal, a message transceiver device, a game console, a tablet device, a medical device, a fitness device, a personal digital assistant, etc. The electronic device can communicate with the stylus, and the communication method is not limited, for example, communication can be achieved through Bluetooth or the like.

[0059] The data processing method comprises the following steps:

[0060] S11: In response to the collection signal, obtaining color parameters obtained by the stylus pen based on the light collected by the pen tip assembly 10 .

[0061] The acquisition signal can be generated by the user pressing a physical button on the stylus, or it can be generated by a virtual button on the software, or it can be generated when the relevant application on the electronic device is started. After obtaining the acquisition signal, the collection light signal can be collected all the time. For example, after the stylus is started, it starts to collect light signals and communicates with the electronic device in real time, so as to transmit the obtained color parameters to the electronic device in real time. In addition, the collection light signal can also be collected at a preset frequency, or it can be collected when needed. After the stylus obtains the acquisition signal, the collection component 1 collects the light in the area pointed by the pen core 41. The light is received by the optical sensor of the stylus after total reflection and diffuse reflection in sequence. The optical sensor converts the light signal into an electrical signal, and the color parameters can be obtained based on the electrical signal.

[0062] S12: Sending the color parameter to an electronic device that is communicatively connected to the stylus pen, so that the electronic device obtains a color result based on the color parameter, wherein the color result is used to characterize a display effect, and implements a corresponding function based on the color result.

[0063] In this step, the color parameter can be sent in real time, at a predetermined frequency, or when a certain application on the electronic device (the application is related to the object to be controlled, as described later) is started, etc. The color result is used to characterize the display result. For example, as described later, the function to be implemented is to adjust the screen brightness. The color result includes a light intensity value, which is used to characterize the brightness. In this way, the electronic device can adjust the screen brightness according to the light intensity value. For another example, when the function to be implemented is to adjust the screen color, the color structure characterizes the color, etc. In this case, the color result includes a chromaticity value. The electronic device can adjust the screen color according to the chromaticity value, etc. For another example, the function to be implemented is to control the scene set by the camera. The color result includes a chromaticity value. The scene set by the camera is controlled by adjusting the chromaticity value. The color effect can characterize the display effect under the scene. For example, when taking photos in the evening, the scene of the camera can be set to the evening, but it is achieved by collecting the light in the evening. Then the set scene is more realistic and the display effect of the photo is better.

[0064] The above data processing method obtains color parameters based on the light collected by the pen tip assembly in response to the collection signal, and the color parameters or color results are sent to the electronic device. Therefore, signal collection is convenient and the interaction between the stylus pen and the electronic device is convenient.

[0065] Exemplarily, as a possible implementation method, the data processing method implemented by the above steps S11-S12 can also be implemented based on the cloud (server) as the execution entity.

[0066] See also Figure 6 , Figure 6 Another data processing method is disclosed, which can also be applied to a stylus pen. Figure 5 Compared with the embodiment shown in the figure, the difference lies in that the subject for processing the color parameters to obtain the color result is different. Figure 5 The main body of the embodiment shown is a stylus, which only sends color parameters. Figure 6 In the embodiment shown, the stylus only sends the color result, and of course, the color result is also used to characterize the display effect. In more detail, the data processing method includes the following steps:

[0067] S21: in response to the acquisition signal, obtaining color parameters obtained by the stylus based on the light collected by the pen tip assembly; this step refers to the description of step S11 and will not be repeated here.

[0068] S22: Process the color parameters to obtain a color result, where the color result is used to characterize a display effect;

[0069] S23: Sending the color result to an electronic device that is communicatively connected to the stylus pen, so that the electronic device implements a corresponding function based on the color result.

[0070] In the above implementation, since the stylus pen only sends the color result to the electronic device, the amount of data transmitted between the stylus pen and the electronic device is relatively small, thus avoiding problems such as transmission delay.

[0071] Exemplarily, as a possible implementation method, the data processing method implemented by the above steps S21-S23 can also be implemented based on the cloud (server) as the execution entity.

[0072] In a fourth aspect, the present application discloses a data processing method. The method can be applied to an electronic device. The electronic device can be any of the devices described above. The method comprises the following steps:

[0073] Receiving a color parameter or a color result sent by a stylus pen that is communicatively connected to the electronic device, wherein the color parameter or the color result is obtained by the data processing method of the third aspect, that is, the color parameter or the color result comes from the stylus pen;

[0074] See also Fig.10 , Fig.10 Some components of the electronic device related to this application are shown in FIG. Fig.10 It can be seen that the communication component communicates with the corresponding component of the stylus, such as Bluetooth communication, etc., to receive the color parameters or color results sent from the stylus.

[0075] A corresponding function is implemented based on the color result.

[0076] Continue to see Fig.10 After the processor obtains the color result, it can call the corresponding control to implement the corresponding function.

[0077] The data processing method is further described as follows in conjunction with specific drawings:

[0078] See also Figure 7 , Figure 7 The present invention is a flow chart of a data processing method applied to an electronic device, wherein the data processing method is used to adjust the screen brightness of the electronic device, and comprises the following steps:

[0079] S31: receiving a color parameter or a color result sent by a stylus pen that is communicatively connected to an electronic device, wherein the color result includes a light intensity value.

[0080] In this step, the color parameters or color results may be received in real time, or may be received based on a preset frequency, or may start receiving when the stylus touches the application associated with the object to be controlled on the screen, or when the user operates a brightness progress bar displayed on the screen.

[0081] S32: Process the light intensity value to obtain display brightness.

[0082] In this step, any technology may be used to process the light intensity value to obtain the display brightness, which will not be described in detail.

[0083] S33: Adjust the screen brightness according to the display brightness.

[0084] In this step, the processor of the electronic device will call the corresponding control to adjust the brightness, so that the user does not need to slide the brightness bar displayed on the screen to adjust the screen brightness. Therefore, the data processing method automatically adjusts the brightness according to the color parameter or color result from the stylus, making the brightness adjustment convenient.

[0085] See also Figure 8 , Figure 8 The data processing method shown is applied to a flowchart of an electronic device, wherein the data processing method is used to adjust the screen color of the electronic device, and comprises the following steps:

[0086] S41: receiving color parameters or color results sent by a stylus pen that is communicatively connected to an electronic device, wherein the color results include chromaticity values.

[0087] How to implement this step can refer to step S31 and will not be described in detail.

[0088] S42: Process the chromaticity value to obtain the screen color.

[0089] How to process the chromaticity value to obtain the screen color can be any technology, for example, the chromaticity value includes a horizontal coordinate x and a vertical coordinate y (also referred to as chromaticity value xy in the industry). The screen color is obtained according to the chromaticity value.

[0090] S43: Adjust screen color.

[0091] In this step, the screen color includes the RGB value, color style and color temperature of the screen, etc. The same as the above principle, after the stylus touches the interface for adjusting the screen color, the electronic device receives the chromaticity value and obtains the screen color, and then automatically calls the corresponding control to adjust the screen color. Finally, the data processing method automatically adjusts the screen color according to the color parameters or color results from the stylus, making the screen color adjustment convenient.

[0092] See also Fig. 9 , Fig. 9The data processing method shown is applied to an electronic device to set a scene of a camera.

[0093] S51: receiving a color parameter or a color result sent by a stylus pen that is in communication with the electronic device, wherein the color result includes a chromaticity value;

[0094] How to receive the color parameters or color results can refer to the description of step S31, wherein the receiving can start when the stylus touches the application associated with the object to be controlled on the screen. Specifically in this embodiment, when the user needs to start the camera function, he will click on the camera icon on the screen with his hand or use the stylus to touch the screen. Then, the stylus starts collecting through the collection part of the pen tip assembly, so that the electronic device obtains the color parameters or color results.

[0095] S52: Process the chromaticity value to obtain the color temperature.

[0096] How to obtain the color temperature through the chromaticity value can be achieved by any technology, which will not be described in detail.

[0097] S53: Set the camera scene according to color temperature.

[0098] In this step, for example, if the user takes a photo in the evening, the processor of the electronic device will set the camera scene to evening according to the color temperature, so that the photo display effect is better and more beautiful.
