[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0030] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0031] Before introducing the embodiments of the present disclosure, the terms and application backgrounds involved in the embodiments of the present disclosure are first explained:

[0032] Physical resolution: also called standard resolution, refers to the original resolution of the image displayed on the screen, also called true resolution. The optimal resolution of the screen, that is, the mathematical expression of the number of pixel rows and columns actually existing on the screen, is an inherent parameter of the display and cannot be adjusted. It means the maximum number of pixels that can be displayed on the screen.

[0033] Logical resolution: The resolution of the screen display, calculated by physical resolution and zoom factor: physical resolution / zoom factor = logical resolution. The larger the zoom factor, the smaller the logical resolution, the more display pixels each physical pixel corresponds to, and the larger the display font. For example: the physical resolution is 1920×1080, the zoom factor is 1.2, and the logical resolution is 1536×864. One physical pixel corresponds to 1.2 display pixels, and the display font becomes larger.

[0034] At present, the screen sizes and resolutions of electronic devices are becoming more and more diverse. For a screen of a fixed size, different resolutions have different display effects. Therefore, it is necessary to adjust the resolution to achieve the best screen display effect.

[0035] In the prior art, the physical resolution of the screen is adjusted by the default zoom factor to obtain the logical resolution, and the best screen display effect is achieved by the logical resolution. The specific method is: determine the ratio of the horizontal resolution in the physical resolution to the default zoom factor, and use the ratio as the horizontal resolution in the logical resolution; determine the ratio of the vertical resolution in the physical resolution to the default zoom factor, and use the ratio as the vertical resolution in the logical resolution.

[0036] For example, the physical resolution of the screen is 1920×1080, and the default zoom factor is 1.25, then the logical resolution is: 1920 / 1.25=1536, 1080 / 1.25=864; that is: 1536×864.

[0037] However, since different users have different requirements for display effects, the logical resolution obtained by adjusting the physical resolution of the screen by the default zoom factor is fixed, and thus cannot meet the requirements of different users, resulting in a poor user experience.

[0038] Therefore, how to improve the diversity of logic resolution to meet the display effect requirements of different users has become an urgent problem to be solved.

[0039] In order to solve the above problems, the inventor's technical concept is as follows: first, according to the default logical resolution and the preset restriction conditions, at least one zoom factor corresponding to the screen is determined, and then a zoom control corresponding to at least one zoom factor is displayed, and the logical resolution is adjusted twice according to the user's triggering operation on any zoom control. In this way, the user can customize the logical resolution and then adjust the display ratio of the screen to meet the display effect requirements of different users. Therefore, the user experience is improved.

[0040] The application scenarios of the embodiments of the present disclosure are explained below: Figure 1 A schematic diagram of an application scenario of a method for adjusting screen resolution provided by an embodiment of the present disclosure is shown in FIG. Figure 1 As shown, the application scenario includes: an electronic device 11, a processing unit 12, a screen 13, and a storage unit 14.

[0041] Among them, the screen 13 can be an external screen or a built-in screen. Among them, the processing unit 12 can obtain the default logical resolution of the screen and determine at least one zoom factor corresponding to the screen. The processing unit 12 can also display the zoom control corresponding to the zoom factor. The processing unit 12 can also receive the trigger operation of any zoom control and adjust the default logical resolution according to the target zoom factor corresponding to any zoom control. Among them, the executor of the present disclosure is an electronic device, which can specifically be a mobile phone, a tablet, a computer, a server and other devices. The audio permission processing method provided in the embodiment of the present disclosure is described in detail using a detailed embodiment below.

[0042] refer to Figure 2 , Figure 2 A flowchart of a method for adjusting screen resolution provided in an embodiment of the present disclosure. The present disclosure embodiment is described by taking an electronic device as an example. The method includes:

[0043] S201. Obtain a default logical resolution of the screen, where the default logical resolution is obtained by scaling the physical resolution of the screen according to a default scaling factor.

[0044] In this step, the default logical resolution is the display resolution of the screen. In some embodiments, the default logical resolution of the screen is determined based on the PPI (Pixels Per Inch) of the screen and the physical resolution of the screen.

[0045] Optionally, the steps for obtaining the default logical resolution of the screen are: determining the number of pixels per inch (PPI) in the screen, and determining a target PPI range to which the PPI belongs from multiple preset PPI ranges; determining a default scaling factor corresponding to the target PPI range; and scaling the physical resolution of the screen according to the default scaling factor to obtain a default logical resolution.

[0046] Among them, the screen of the electronic device can be a built-in screen or an external screen. In this embodiment, no specific requirements are made for multiple preset PPI ranges. Optionally, since the size of the built-in screen is generally smaller than the external screen, in order to improve the display effect of the built-in screen and the external screen, multiple preset PPI ranges corresponding to the built-in screen and multiple preset PPI ranges corresponding to the external screen are set respectively.

[0047] Table 1 is a table of correspondence between multiple preset PPI ranges and default zoom factors provided by the embodiment of the present disclosure. Among them, the correspondence between multiple preset PPI ranges and default zoom factors corresponding to the built-in screen is as follows: the default zoom factor corresponding to the preset PPI range of less than 140 and greater than or equal to 0 (<140) is 1.0; the default zoom factor corresponding to the preset PPI range of less than 170 and greater than or equal to 140 (140-170) is 1.25; the default zoom factor corresponding to the preset PPI range of less than 200 and greater than or equal to 170 (170-200) is 1.5; the default zoom factor corresponding to the preset PPI range of less than 230 and greater than or equal to 200 (200-230) is 1.666; the default zoom factor corresponding to the preset PPI range of less than 290 and greater than or equal to 230 (230-290) is 2.0; the default zoom factor corresponding to the preset PPI range of greater than or equal to 290 (≥290) is 2.5.

[0048] Among them, the correspondence between multiple preset PPI ranges corresponding to the external screen and the default zoom factors is: the default zoom factor corresponding to the preset PPI range is less than 75 and greater than or equal to 0 (<75) is 1.0; the default zoom factor corresponding to the preset PPI range is less than 125 and greater than or equal to 75 (75~125) is 1.25; the default zoom factor corresponding to the preset PPI range is less than 150 and greater than or equal to 125 (125~150) is 1.5; the default zoom factor corresponding to the preset PPI range is less than 175 and greater than or equal to 150 (150~175) is 1.875; the default zoom factor corresponding to the preset PPI range is greater than or equal to 175 (≥175) is 2.0.

[0050]

[0051] S202: Determine at least one zoom factor corresponding to the screen according to a default logical resolution and preset restriction conditions.

[0052] In some embodiments, the preset restriction condition is used to determine at least one zoom factor corresponding to the screen through the adjusted logical resolution. The following is a detailed description of determining at least one zoom factor corresponding to the screen through the restriction conditions of three situations:

[0053] In the first case, the default logical resolution includes the horizontal resolution. The preset constraint condition may be that the adjusted horizontal resolution is a common horizontal resolution. Accordingly, according to the default logical resolution and the preset constraint condition, determining at least one zoom factor corresponding to the screen includes steps (a1) to (a3):

[0054] (a1) Obtain multiple candidate zoom factors.

[0055] In some embodiments, the plurality of candidate zoom factors are arithmetic progressions. Optionally, the minimum value of the arithmetic progression is 0.5, the maximum value is 2.0, and the tolerance of the arithmetic progression can be 0.1; accordingly, the plurality of candidate zoom factors include: 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0.

[0056] In other embodiments, multiple candidate zoom factors are determined based on the default zoom factor. Optionally, the multiple candidate zoom factors are N; N values ​​can be set first, and the N candidate zoom factors are determined based on the ratio of the N values ​​to the default zoom factor. For example, the multiple candidate zoom factors are 4, and the N values ​​can be set first to 0.8, 1.0, 1.2 and 1.5; the default zoom factor is 1.0; then the multiple candidate zoom factors are: 0.8, 1.0, 1.2 and 1.5.

[0057] (a2) For each candidate zoom factor, determine a first ratio of the lateral resolution to the candidate zoom factor.

[0058] Exemplarily, the horizontal resolution is 1536, the candidate zoom factor is 1.2, and the first ratio of the horizontal resolution to the candidate zoom factor is: 1280.

[0059] (a3) If the first ratio is any one of a plurality of common horizontal resolutions, it is determined that the restriction condition is satisfied, and at least one candidate zoom factor satisfying the restriction condition is determined as at least one zoom factor corresponding to the screen.

[0060] Optionally, the plurality of common horizontal resolutions include at least one of the following: 768, 1024, 1200, 1280, 1366, 1440, 1536, 1600, 1920. Exemplarily, the first ratio of the horizontal resolution to the candidate zoom factor is 1280, and the first ratio (1280) is a common horizontal resolution, and the candidate zoom factor of 1.2 is determined as the zoom factor corresponding to the screen.

[0061] Here, since the adjusted horizontal resolution is a common horizontal resolution, and the display effect of the common horizontal resolution is more in line with the user's requirements, it is more convenient for the user to quickly select a suitable resolution, thereby further improving the user experience.

[0062] In the second case, the default logical resolution includes a horizontal resolution and a vertical resolution; accordingly, determining at least one zoom factor corresponding to the screen according to the default logical resolution and the preset restriction condition may include the following steps (b1) to (b3):

[0063] (b1) Obtain multiple candidate zoom factors.

[0064] (b2) For each candidate zoom factor, determine a first ratio of the horizontal resolution to the candidate zoom factor and a second ratio of the vertical resolution to the candidate zoom factor.

[0065] Exemplarily, the horizontal resolution is 1536 and the vertical resolution is 864. If the candidate zoom factor is 1.2, the first ratio of the horizontal resolution to the candidate zoom factor is 1280; the second ratio of the vertical resolution to the candidate zoom factor is 720.

[0066] (b3) If the first ratio and / or the second ratio is an integer, it is determined that the restriction condition is satisfied, and at least one candidate zoom factor satisfying the restriction condition is determined as at least one zoom factor corresponding to the screen.

[0067] Exemplarily, the first ratio of the horizontal resolution to the candidate zoom factor is 1280, and the second ratio of the vertical resolution to the candidate zoom factor is 720. Wherein, the first ratio and the second ratio are integers, and if the restriction condition is satisfied, the candidate zoom factor of 1.2 is determined as the zoom factor corresponding to the screen.

[0068] Here, since the adjusted horizontal resolution and / or vertical resolution is an integer, the integer resolution can reduce calculation errors when matching the screen, thereby improving the screen display effect. This makes it easier for users to quickly select a suitable resolution, thereby further improving the user experience.

[0069] In the third case, the screen is an external screen; the size of the external screen is generally large. In order to ensure the display effect of the external screen, the maximum logical resolution is generally set close to the physical resolution of the external screen. Accordingly, under the premise of satisfying the first case and / or the second case, the minimum zoom factor of the at least one zoom factor can be further limited.

[0070] Optionally, before determining at least one candidate zoom factor that meets the restriction condition as at least one zoom factor corresponding to the screen, the step also includes: selecting a minimum zoom factor with the smallest value from at least one zoom factor; determining a third ratio of the default logical resolution to the minimum zoom factor; if the difference between the third ratio and the physical resolution is less than or equal to a preset difference, executing the step of determining at least one candidate zoom factor that meets the restriction condition as at least one zoom factor corresponding to the screen.

[0071] The third ratio of the default logical resolution to the minimum zoom factor includes: the ratio of the horizontal logical resolution to the minimum zoom factor, and the ratio of the vertical logical resolution to the minimum zoom factor. In this embodiment, the value of the preset difference is not specifically limited. For example, the preset difference may be 1, 5, or 10.

[0072] Exemplarily, the preset difference is 1, and the minimum zoom factor is 0.8. The physical resolution of the external screen is 1920×1080; the default zoom ratio is 1.25, and the logical resolution is 1536×846; wherein, the third ratio of the horizontal logical resolution to the minimum zoom factor is 1920, and the third ratio of the vertical logical resolution to the minimum zoom factor is 1080; if the difference between the third ratio and the physical resolution is less than the preset difference 1, then continue to perform the step of determining at least one candidate zoom factor that meets the restriction condition as at least one zoom factor corresponding to the screen.

[0073] It should be noted that if the difference between the third ratio and the physical resolution of the screen is greater than the preset difference, the minimum zoom factor is deleted from at least one zoom factor; continue to select the minimum zoom factor with the smallest value from at least one zoom factor; until the difference between the third ratio and the physical resolution of the screen is less than or equal to the preset difference, the step of determining at least one candidate zoom factor that meets the restriction condition as at least one zoom factor corresponding to the screen is executed.

[0074] Exemplarily, the preset difference is 10, and the minimum zoom factor is 0.5. The physical resolution of the external screen is 1920×1080; the default zoom ratio is 1.25, and the logical resolution is 1536×846; wherein, the third ratio of the horizontal logical resolution to the minimum zoom factor is 3072 (greater than 1920), and the third ratio of the vertical logical resolution to the minimum zoom factor is 1692 (greater than 1080); the difference between the third ratio and the physical resolution is greater than the preset difference of 10, and the minimum zoom factor of 0.5 is deleted. Further, continue to select the minimum zoom factor of 0.8 with the smallest value from at least one zoom factor; at this time, the difference between the third ratio and the physical resolution is less than the preset difference of 10, and then continue to execute the step of determining at least one candidate zoom factor that meets the restriction condition as at least one zoom factor corresponding to the screen.

[0075] It should be noted that in this step, when determining at least one zoom factor, the restriction conditions of the above three situations may be satisfied at the same time, or the restriction conditions of any two of the above three situations may be satisfied, or the restriction conditions of only one of the three situations may be satisfied.

[0076] In some other embodiments, the restriction condition is: a correspondence between a preset PPI range, a default zoom factor, and at least one zoom factor. Accordingly, determining at least one zoom factor corresponding to the screen according to the default logical resolution and the preset restriction condition includes: determining a default zoom factor corresponding to the default logical resolution; determining a target PPI range corresponding to the default zoom factor; and determining at least one zoom factor corresponding to the screen from the correspondence between the preset PPI range, the default zoom factor, and at least one zoom factor according to the target PPI range and the default zoom factor.

[0077] The corresponding relationship when the screen is built-in is different from the corresponding relationship when the screen is external. For example, as shown in Table 2 below, Table 2 is a table of the corresponding relationship between the preset PPI range, the default zoom factor and at least one zoom factor provided in an embodiment of the present disclosure. The screen is a built-in screen or an external screen.

[0078] Optionally, the screen is a built-in screen, and the at least one zoom factor includes at least one of the following: 0.8, 1.0, 1.2 and 1.5; wherein the corresponding relationship between the preset PPI range, the default zoom factor and the at least one zoom factor is as follows: the preset PPI range <140, the default zoom factor 1.0 corresponding to at least one default zoom factor includes: 0.8, 1.0, 1.2 and 1.5; the preset PPI range 140-170, the default zoom factor 1.0 corresponding to at least one default zoom factor includes: 0.8, 1.0, 1.2 and 1.5; the preset PPI range 170-200, the default zoom factor At least one default zoom factor corresponding to a magnification of 1.5 includes: 0.8, 1.0, 1.2 and 1.5; at least one default zoom factor corresponding to a preset PPI range of 200-230 and a default zoom factor of 1.666 includes: 0.8, 1.0, 1.2 and 1.5; at least one default zoom factor corresponding to a preset PPI range of 230-290 and a default zoom factor of 2.0 includes: 0.8, 1.0, 1.2 and 1.5; at least one default zoom factor corresponding to a preset PPI range ≥290 and a default zoom factor of 2.5 includes: 0.8, 1.0, 1.2 and 1.5.

[0079] Optionally, the screen is an external screen, and the at least one zoom factor includes at least one of the following: 0.5, 0.53, 0.67, 0.75, 0.8, 1.0, 1.2, 1.25, 1.333, 1.5 and 1.6. Among them, the correspondence between the preset PPI range, the default zoom factor and at least one zoom factor is as follows: the preset PPI range is less than 75, and the default zoom factor is 1.0, and the at least one default zoom factor corresponding to the default zoom factor includes: 1.0, 1.25 and 1.5; the preset PPI range is 75-125, and the at least one default zoom factor corresponding to the default zoom factor is 1.25 includes: 0.8, 1.0, 1.2 and 1.5; the preset PPI range is 125-150, and the at least one default zoom factor corresponding to the default zoom factor is 1.5 includes: 0.67, 1.0, 1.2 and 1.5; the preset PPI range is 150-175, and the at least one default zoom factor corresponding to the default zoom factor is 1.875 includes: 0.53, 0.8, 1.0, 1.333 and 1.6; the preset PPI range is ≥175, and the at least one default zoom factor corresponding to the default zoom factor is 2.0 includes: 0.5, 0.75, 1.0, 1.25 and 1.5.

[0080] Table 2

[0081]

[0082]

[0083] It should be noted that different zoom factors in Table 2 correspond to different zoom levels. According to the font size of the displayed content, the zoom factors are divided into five zoom levels: small, smaller, normal, larger, and larger.

[0084] S203: Display a zoom control corresponding to at least one zoom factor.

[0085] Optionally, the zoom control is displayed only when the user triggers an adjustment operation. Accordingly, this step is: in response to the adjustment operation for the screen resolution, a zoom control interface is displayed, wherein the zoom control interface includes at least one zoom control corresponding to the zoom multiple.

[0086] In this step, the adjustment operation can be any operation that triggers the zoom control interface. The adjustment operation can be a click operation, a slide operation, or a voice operation. Optionally, the adjustment operation is a single click operation on the "resolution zoom factor" control. Figure 3 As shown, the "Resolution Scaling Factor" control is a scaling factor selection box.

[0087] Among them, the zoom control can include the corresponding zoom multiple, which is convenient for users to distinguish and select. Figure 3 As shown, the zoom control interface includes zoom controls corresponding to four zoom factors, namely: a zoom control corresponding to a zoom factor of 0.8, a zoom control corresponding to a zoom factor of 1.0, a zoom control corresponding to a zoom factor of 1.2, and a zoom control corresponding to a zoom factor of 1.5.

[0088] S204: In response to a triggering operation on any zoom control, the default logical resolution is adjusted according to a target zoom factor corresponding to any zoom control.

[0089] Optionally, the default logical resolution includes horizontal resolution and vertical resolution; accordingly, this step is: determine a fourth ratio of the horizontal resolution to the target zoom factor, and adjust the horizontal resolution to the fourth ratio; determine a fifth ratio of the vertical resolution to the target zoom factor, and adjust the vertical resolution to the fifth ratio.

[0090] Exemplarily, the default logical resolution is 1536×864, wherein the horizontal resolution is 1536 and the vertical resolution is 864. The target zoom factor is 1.25. The fourth ratio of the horizontal resolution to the target zoom factor is determined to be 1280, and the horizontal resolution of 1536 is adjusted to 1280; the fifth ratio of the vertical resolution to the target zoom factor is determined to be 720, and the vertical resolution of 864 is adjusted to 720.

[0091] The screen resolution adjustment method provided in this embodiment first scales the physical resolution of the screen according to a default scaling factor to obtain a default logical resolution; then determines at least one scaling factor corresponding to the screen based on the default logical resolution and preset restrictions; finally, displays a zoom control corresponding to the scaling factor, and performs a secondary adjustment on the logical resolution based on the user's selection operation on any zoom control, that is, implements a function for users to customize the logical resolution, so that when users use the screen to browse content, they can easily adjust the logical resolution of the screen to adjust the display ratio of the browsed content, thereby improving the user experience of the electronic device.

[0092] Figure 4 This is a structural block diagram of a screen resolution adjustment device provided by an embodiment of the present disclosure, which is applied to a terminal device with an application installed. Figure 4 The device for adjusting the screen resolution includes: an acquisition module 401, a determination module 402, a display module 403 and an adjustment module 404.

[0093] The acquisition module 401 is used to acquire a default logical resolution of the screen, wherein the default logical resolution is obtained by scaling the physical resolution of the screen according to a default scaling factor;

[0094] A determination module 402, configured to determine at least one zoom factor corresponding to the screen according to the default logical resolution and a preset restriction condition;

[0095] Display module 403, used to display at least one zoom control corresponding to the zoom factor;
