These drawings and the written description are not intended to restrict the scope of the present application concept in any way, but to illustrate the present application concept to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0034] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, the same numbers are used to indicate the same or similar components. The embodiments described in the following exemplary embodiments are not meant to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the appended claims.

[0035] Figure 1 An application scenario schematic diagram of an aperture value adjustment method provided by an embodiment of the present application, combined with the illustrated scenario, for example: for a full-screen mobile phone, in order to improve the screen ratio, the lens is arranged at the lower part of the screen, and when taking a photo, light enters the lens through the screen. The lens is fixed at the lower part of the screen, the aperture of the lens is fixed, and the aperture determines the amount of light entering the lens.

[0036] It should be noted that the present application does not limit the mobile device to a mobile phone, but can also be other full-screen mobile devices.

[0037] The technical solutions of the present application and the technical solutions of the present application will be described in detail below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. In the description of the present application, unless otherwise explicitly specified and limited, each term should be understood in a broad sense in the art. The embodiments of the present application will be described below with reference to the drawings.

[0038] Figure 2 This is a flowchart illustrating an aperture value adjustment method provided in an embodiment of this application. The method includes the following steps:

[0039] S201, Determine the first distance from the lens optical center to the screen, the second distance from the lens optical center to the lens element, and the lens focal length.

[0040] As an example, the implementing entity of this embodiment can be an aperture value adjustment device, which can be implemented in various ways. For example, it can be program software, or a medium storing relevant computer programs, such as a USB flash drive; or, the device can also be a physical device that integrates or installs relevant computer programs, such as a chip, a smart terminal, a computer, a server, etc.

[0041] It should be noted that the solution in this application is for full-screen mobile devices, that is, mobile devices with the camera at the bottom of the screen (hereinafter referred to as mobile devices).

[0042] Since the mobile device's camera is located at the bottom of the screen, the camera's position cannot be changed, the camera's aperture cannot be switched, and the mobile device's first distance, second distance, and camera focal length are fixed parameters that were determined at the time the mobile device was manufactured.

[0043] Optionally, the first distance, the second distance, and the lens focal length can be obtained from the hardware information of the mobile device.

[0044] Below, in conjunction with Figure 3 Explain the structure of the lens and screen.

[0045] Figure 3 This is a schematic diagram of the lens and screen structure provided in an embodiment of this application. Figure 3 As shown, the lens is located at the bottom of the screen, with its optical center inside the lens. The first distance from the optical center to the center of the screen is L1, and the second distance from the optical center to the center of the lens element is L2. θ is half of the lens's maximum angle of view, which is the maximum range of light that the lens can cover. Point F is the intersection of the edge of the light ray and the tangent to the screen when the lens is at its maximum angle of view, and the distance from the center of the screen to point F is r1. r2 is the distance from the intersection of the line connecting the optical center of the lens and point F with the lens element to the center of the lens element, which is half of the lens's light-transmitting diameter.

[0046] S202. Based on the preset correspondence, the first distance, and the second distance, determine the first correspondence between the aperture value and the screen light-transmitting radius, wherein the preset correspondence is the correspondence between the aperture value, the lens focal length, and the lens light-transmitting diameter.

[0047] Optionally, the preset corresponding relationship is a calculation formula of the aperture value, i.e., aperture value = lens focal length / lens light diameter. The smaller the aperture value is, the larger the lens light diameter is, and the larger the lens light quantity is.

[0048] It can be understood that the aperture of the mobile device is fixed and cannot be adjusted. Through the first corresponding relationship, the aperture value can be converted into the screen light radius, so as to indirectly adjust the aperture value through the screen light radius, thereby meeting the photographing needs of the user in different scenes.

[0049] S203, adjusting the screen light radius based on the first corresponding relationship, so as to adjust the aperture value to a target aperture value.

[0050] It can be understood that for the mobile device, the screen light radius can be realized by controlling the pixels of the screen. The lens corresponding to the pixel light can pass light, and the lens corresponding to the pixel without light can not pass light. The control of the pixels of the screen can adjust the screen light radius range, thereby meeting the photographing needs of the user in multiple scenes.

[0051] The aperture value adjustment method provided by the embodiment of the present application determines a first distance from a lens optical center to a screen, a second distance from the lens optical center to a lens lens, and a lens focal length; determines a first corresponding relationship between the aperture value and a screen light radius based on a preset corresponding relationship, the first distance, and the second distance, wherein the preset corresponding relationship is a corresponding relationship among the aperture value, the lens focal length, and the lens light diameter; and adjusts the screen light radius based on the first corresponding relationship, so as to adjust the aperture value to a target aperture value. Through the above scheme, the actual aperture value can be adjusted in the case of fixed aperture, thereby flexibly adjusting the light quantity and meeting the photographing needs in multiple scenes.

[0052] On the basis of any one of the above embodiments, the following will be described in combination with Figure 4 The detailed process of adjusting the aperture value is described.

[0053] Figure 4 A flowchart of an aperture value adjustment method provided by the embodiment of the present application is shown in FIG. 1. As shown in FIG. 1, the method comprises the following steps. Figure 4

[0054] S401, determining a first distance from a lens optical center to a screen, a second distance from the lens optical center to a lens lens, and a lens focal length.

[0055] It should be noted that the execution process of S401 is described in S201, which will not be described here.

[0056] S402, establishing a second corresponding relationship among a lens view angle, the first distance, and a screen light radius based on the Pythagorean theorem and the first distance. ​

[0057] Specifically, referring to Figure 3 , according to the Pythagorean theorem of triangle, L1 is the first distance from the lens optical center to the screen, tanθ=r1 / L1 can be obtained, wherein θ is 1 / 2 of the lens view angle, and a second correspondence relationship between the lens view angle and the first distance and the screen half light radius is obtained.

[0058] Wherein, tanθ and r1 are variables, L1 is a fixed value, the values of tanθ and r1 after the change comply with the second correspondence relationship, and tanθ changes with the change of r1.

[0059] S403, based on the Pythagorean theorem of triangle and the second distance, a third correspondence relationship between the lens view angle and the second distance and the lens half light diameter is established.

[0060] Specifically, referring to Figure 3 , according to the Pythagorean theorem of triangle, L2 is the second distance from the lens optical center to the lens lens, tanθ=r2 / L2 can be obtained, wherein θ is 1 / 2 of the lens view angle, and r2 is 1 / 2 of the lens half light diameter, and a third correspondence relationship between the lens view angle and the second distance and the lens half light diameter is obtained.

[0061] Wherein, tanθ and r2 are variables, L2 is a fixed value, the values of tanθ and r2 after the change comply with the third correspondence relationship, tanθ changes with the change of r2, and r2 changes with the change of r1.

[0062] Optionally, S402 and S403 can be executed simultaneously.

[0063] S404, according to the third correspondence relationship and the second correspondence relationship, a fourth correspondence relationship between the lens half light diameter and the screen half light radius, the first distance and the second distance is obtained.

[0064] Optionally, the second correspondence relationship tanθ=r1 / L1 is substituted into the third correspondence relationship tanθ=r2 / L2, and the fourth correspondence relationship r2=r1*L2 / L1 is obtained, wherein r2 is 1 / 2 of the lens half light diameter, and the fourth correspondence relationship between the lens half light diameter and the screen half light radius, the first distance and the second distance is obtained.

[0065] S405, based on the preset correspondence relationship, the second correspondence relationship and the third correspondence relationship, the first correspondence relationship is established.

[0066] Optionally, the lens half light diameter=2*r2, r2=r1*L2 / L1 is substituted into the calculation formula of the aperture value, and the first correspondence relationship aperture value=f*L1 / 2r1L2 is obtained. Wherein, the lens focal length f, the first distance L1 and the second distance L2 are fixed values, and according to the first correspondence relationship, the aperture value can be calculated by the screen half light radius.

[0067] S406, acquire a target aperture value, and acquire a target screen light passing radius according to the target aperture value and the first correspondence.

[0068] Optionally, the target aperture value is determined by the mobile device according to a photographing scene. For example, if the user uses the mobile device to take a photograph in a dim environment, the light quantity needs to be increased to improve the photographing effect, and in this case, a lower target aperture value needs to be set.

[0069] Optionally, the target aperture value is determined according to a user setting. For example, if the user wants to increase the exposure of a photographed photo, the user selects a corresponding option in the mobile device, and the mobile device sets a lower aperture value corresponding to the selected option.

[0070] S407, acquire a lens view angle.

[0071] The lens view angle is the maximum range that can be covered by the lens, which is determined when the mobile device is manufactured.

[0072] The lens view angle is described below. Figure 5

[0073] The lens view angle is described below. Figure 5 The lens view angle is described below.

[0074] Optionally, according to the Pythagorean theorem, L1 is the first distance from the lens optical center to the screen, and r1=L1*tanθ, where θ is 1 / 2 of the lens view angle, and L1 and θ are fixed values, so the value of r1 can be calculated.

[0075] Figure 3 For example, in the range of the radius r1, the light can be captured by the camera.

[0076] For example, in the range of the radius r1, the light can be captured by the camera.

[0077] S409, determine whether the target screen light passing radius is less than or equal to the screen light passing radius threshold.

[0078] If yes, perform S410.

[0079] S410, adjust the pixels in the target screen light passing radius to a light passing state, and adjust the pixels outside the target screen light passing radius and within the screen light passing radius threshold to a non-light passing state.

[0080] ​The following describes the pixel adjustment in combination with a scene example. Figure 6 The pixel adjustment is described.

[0081] Figure 6 A pixel adjustment schematic diagram is provided for the embodiments of the present application. Wherein, R1 is a screen light passing radius threshold value, the light in the range of the circle corresponding to R1 can be captured by the lens. R2 is a target screen light passing radius, the range of the circle corresponding to R2 is calculated according to the target aperture value.

[0082] In combination with a scene example, when R2 is determined, and R2 is less than or equal to R1, the pixels in the range of R2 are adjusted to the light passing state, at this time, the light in the range of R2 can be captured by the lens, the pixels located outside the range of R2 and located in the range of R1 are adjusted to the non-light passing state, since the pixels are not light passing, the light in the corresponding range cannot be captured by the lens, thereby realizing the light amount adjustment.
