[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0025] The parameter adjustment method provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0026] Figure 1 Detailed description of the invention is given in detail below. It is a flow chart of a parameter adjustment method provided in an embodiment of the present application, and the parameter adjustment method is applied to a stylus pen.

[0027] Among them, Figure 2 As shown in FIG. 1 , the stylus pen 200 includes a stylus pen body 201 and a flexible screen 202. The stylus pen body 201 is provided with a cavity, and the flexible screen 202 is provided in the cavity, and the flexible screen 202 can extend out of the cavity (i.e., extend out of the stylus pen body 201) or be retracted into the cavity. The stylus pen 200 is also provided with an opening 203, and the flexible screen 202 can extend out of the stylus pen body 201 from the opening 203. The extended state can be referred to in FIG. Figure 2 The portion extending out of the stylus body 201 can also be retracted into the cavity through the opening 203. The retracted state can be referred to Figure 3 .

[0028] like Figure 1As shown, the parameter adjustment method may include:

[0029] Step 101: Obtain a first length of the flexible screen on the stylus pen extending out of the stylus pen body.

[0030] As for the method for measuring the length of the flexible screen extending out of the stylus body, for example, an infrared transmitter can be set at the opening, and an infrared receiver can be set at the end where the flexible screen can extend out of the opening, and the extension length can be calculated based on the emission time and reception time of the infrared ray.

[0031] Step 102: According to a preset correspondence between the extended length of the flexible screen and the parameter value of the target parameter of the target device, the parameter value of the target parameter of the target device is adjusted to a parameter value corresponding to the first length.

[0032] The target device described here is the stylus or other electronic devices that have established a communication connection with the stylus, that is, in the embodiment of the present application, the parameter value of the target parameter of the stylus can be adjusted according to the extended length of the flexible screen, and the parameter value of the target parameter of other electronic devices that have established a communication connection with the stylus can also be adjusted according to the extended length of the flexible screen. The target parameters described here may include, but are not limited to, at least one of: focal length, volume, flash brightness, and screen brightness.

[0033] In the embodiment of the present application, the parameter value of the target parameter is adjusted by pulling out or retracting the flexible screen, thereby enriching the function of the flexible screen. In addition, such parameter adjustment operation is relatively simple, and for a stylus or other electronic device without a touch function, it is more convenient for the user to adjust the parameter value of the target parameter, thereby improving the user experience.

[0034] Optionally, when the target parameter is focal length, the preset corresponding relationship between the extended length of the flexible screen and the focal length of the target camera may be:

[0035] When the extended length of the flexible screen is equal to 0, the focal length of the target camera is a default focal length value greater than 0;

[0036] When the extended length of the flexible screen is greater than 0 and less than or equal to L0, the preset corresponding relationship between the extended length of the flexible screen and the focal length of the target camera is: n1=L2 / L0*n;

[0037] When the extended length of the flexible screen is greater than L0, the preset corresponding relationship between the extended length of the flexible screen and the focal length of the target camera is: n1=n.

[0038] Among them, the target camera described here is the camera used for current shooting on the target device. The shooting described here can be: taking pictures or recording videos. n1 represents the focal length value of the target camera corresponding to the extended length of the flexible screen. n represents the maximum focal length of the target camera. L2 represents the extended length of the flexible screen (corresponding to the first length). L0 represents the extended length of the flexible screen corresponding to the maximum focal length of the target camera. Among them, the total length of the flexible screen is L1, L1≥L0>0.

[0039] Thus, step 102: adjusting the parameter value of the target parameter of the target device to a parameter value corresponding to the first length according to a preset correspondence between the extended length of the flexible screen and the parameter value of the target parameter of the target device, may include:

[0040] When the first length is equal to 0, the focal length of the target camera is adjusted to the default focal length value;

[0041] When the first length is greater than 0 and less than or equal to L0, the focal length of the target camera is adjusted to: L2 / L0*n;

[0042] When the first length is greater than L0, the focal length of the target camera is adjusted to n.

[0043] Among them, when adjusting the volume, screen brightness, flash brightness and other parameters according to the extended length of the flexible screen, the adjustment logic is similar to the logic of adjusting the focal length. In order to avoid repetition, it will not be repeated here. It should be noted that when the first length is equal to 0, the parameter values ​​of the volume, screen brightness and flash brightness are the currently set parameter values.

[0044] Optionally, when the target parameter is focal length and the target device is the stylus, it can be set that: L1>L0>0.

[0045] When taking pictures with the stylus, after the flexible screen is stretched out, the longer the stretched length is, the more uneven the force on the stylus may be, the more likely it is to shake, and the worse the quality of the captured image. Therefore, in order to reduce the occurrence of shaking, in an embodiment of the present application, the extended length of the flexible screen corresponding to the maximum focal length of the target camera can be limited, that is, L1>L0. This can reduce the length of the flexible screen stretched by the user, thereby alleviating the uneven force on the stylus and reducing the occurrence of shaking.

[0046] Optionally, when the target parameter is a focal length, step 102: adjusting the parameter value of the target parameter of the target device to a parameter value corresponding to the first length according to a preset correspondence between the extended length of the flexible screen and the parameter value of the target parameter of the target device, may further include:

[0047] According to the preset correspondence between the extended length of the flexible screen and the parameter variable of the target camera, the target parameter variable value corresponding to the first length is determined; the sum of the default focal length value of the target camera and the target parameter variable value is determined as the target focal length value; and the focal length of the target camera is adjusted to the target focal length value.

[0048] The default focal length value of the target camera is the minimum focal length value of the target camera, and is also the focal length value of the target camera when the first length is 0.

[0049] In an embodiment of the present application, a corresponding relationship can be pre-established between the extended length of the flexible screen and the focal length variable, and the focal length of the target camera can be adjusted according to the focal length variable corresponding to the extended length.

[0050] Optionally, when the target parameter is focal length, after obtaining a first length of the flexible screen extending out of the stylus body, the parameter adjustment method further includes: when the first length is greater than 0, displaying a preview image in the target display area.

[0051] Among them, the target display area is the display area of ​​the flexible screen that extends out of the stylus body and has a length less than or equal to the L0 part.

[0052] In the embodiment of the present application, when the focal length is adjusted according to the extended length of the flexible screen, the preview image captured by the target camera can be displayed on the stretched flexible screen for the user to view. Moreover, in the case of L1>L0, the portion of the extended length exceeding L0 (i.e., the portion extended later) can be in the screen-off state, so that, firstly, the user can be reminded that the maximum adjustment focal length has been reached, and secondly, the display area in the working state can be reduced, thereby achieving the purpose of saving power consumption.

[0053] Optionally, when displaying the preview image on the stretched flexible screen, the current corresponding focal length value can also be displayed at the same time to remind the user.

[0054] Optionally, the stylus pen is also provided with a shooting button. After adjusting the focal length, the shooting button can be pressed to shoot while keeping the extended length of the flexible screen unchanged, thereby obtaining a captured image.

[0055] Optionally, after obtaining the captured image, the parameter adjustment method may further include: displaying the captured image; when it is detected that the flexible screen has a retraction action, cropping the image content displayed by the retracted part before the retraction; when an extension action is detected within a preset time length after the retraction action of the flexible screen, restoring the image content displayed by the re-extended part before the retraction and that was cropped.

[0056] In the embodiment of the present application, in addition to adjusting the focal length by extending the flexible screen, the image content can be cropped by retracting the flexible screen after shooting. The image cropping operation is simple and convenient for users. After cropping the image content, if you want to restore all or part of the cropped image content, you can stretch out the flexible screen again, and the cropped image content displayed before the retraction will be restored.

[0057] Optionally, in addition to the above-mentioned image cropping method, a cropping frame of a preset shape can be displayed on the captured image, and a gravity sensor can be set on the stylus to adjust the position of the cropping frame through gravity sensing. Then, based on the current state of the flexible screen (the extended length of the flexible screen is less than the maximum extended length), the size of the cropping frame is adjusted by stretching the flexible screen or retracting the second length of the flexible screen. After determining the size of the cropping frame, the image content outside the cropping frame is cropped and the image content within the cropping frame is retained.

[0058] In summary, in the embodiment of the present application, the parameter value of the target parameter is adjusted by pulling out or retracting the flexible screen, thereby enriching the function of the flexible screen. In addition, such parameter adjustment operation is relatively simple, and for a stylus or other electronic device without a touch function, it is more convenient for the user to adjust the parameter value of the target parameter, thereby improving the user experience.

[0059] It should be noted that the parameter adjustment method provided in the embodiment of the present application can be executed by a parameter adjustment device or a control module in the parameter adjustment device for executing the parameter adjustment method. In the embodiment of the present application, the parameter adjustment device provided in the embodiment of the present application is described by taking the parameter adjustment device executing the parameter adjustment method as an example.

[0069] The second adjustment unit is used to adjust the focal length of the target camera to: L2 / L0*n when the first length is greater than 0 and less than or equal to L0.

[0070] The third adjustment unit is used to adjust the focal length of the target camera to n when the first length is greater than L0.

[0071] Among them, the target camera is set on the stylus; n represents the maximum focal length of the target camera; L2 represents the first length; L0 represents the extended length of the flexible screen corresponding to the maximum focal length of the target camera; wherein L1>L0>0, L1 represents the total length of the flexible screen.

[0072] Optionally, the parameter adjustment device further includes:
