Technical Field
[0001] This application relates to the field of camera technology, specifically to an aperture, an aperture adjustment method, a lens system, a shooting device, and a mobile device. Background Technology
[0002] In a camera, the aperture is a device used to control the amount of light passing through the lens and entering the sensor inside the camera body. Cameras with different aperture sizes produce different photo effects. Nowadays, most cameras have the function of adjusting the aperture size. By adjusting the aperture, the same camera can produce photos with different effects. Adjusting to a large aperture can blur the background of the photo, while adjusting to a small aperture can achieve a large depth of field.
[0003] Nowadays, more and more mobile devices are equipped with lenses of different aperture sizes in their cameras, enabling them to adapt to more shooting needs and environmental changes, and to achieve stronger image resolution. However, too many lenses can also lead to problems such as limited space for internal components, increased heat dissipation burden, and higher consumption of computing resources. Furthermore, lenses with adjustable apertures typically use a mechanical method, where the aperture only switches between a few preset values according to the user's needs, failing to achieve smooth, linear aperture adjustment and limiting the user's shooting experience.

[0073] In practical applications, users have increasingly diverse requirements for photos taken by mobile devices. They not only need mobile device cameras to have superior image resolution and ultra-fast processing speeds, but also to meet their more personalized shooting needs. Currently, the camera devices configured on mobile devices (such as cameras with multiple lens systems in smartphones) have fixed adjustable aperture values, resulting in fixed shooting effects. It's impossible for users to adjust the aperture to a different value unless they switch to another mobile device with the desired aperture, which limits and inconveniences the user experience. The following embodiments of this application disclose a mobile device equipped with a lens system that allows for smooth aperture adjustment. Through electronic control, users can adjust the aperture to the desired size based on any set aperture value, thus achieving a more diverse shooting experience covering the entire aperture range.
[0074] The aperture, aperture adjustment method, lens system, shooting device, and mobile device disclosed in this application are specifically described in the following embodiments.
[0075] Example 1
[0076] Embodiment 1 of this application discloses a shooting device with an adjustable aperture, which allows the user to adjust the aperture to any desired aperture value, thereby achieving more diverse shooting effects.
[0077] like Figure 1 As shown, the shooting device includes a housing 1, a shooting module 2, and a lens system 3. Both the shooting module 2 and the lens system 3 are installed within the housing 1, with the lens system 3 mounted on the shooting module 2. The housing 1 serves as the external frame structure of the shooting device, integrating and protecting the internal components, while also facilitating integration into any electronic device, especially mobile devices. The shooting module 2 is the internal component of the shooting device used to control the taking of photos, enabling it to capture various photos in different environments and scenes according to the user's needs, achieving any desired shooting effect. The lens system 3 is the internal component of the shooting device used to image objects and scenes. Different lens systems 3 can achieve different imaging effects, thus allowing the shooting module 2 to control the capture of photos with different effects. In this embodiment, the lens system 3 has an adjustable aperture, allowing the user to capture photos with different effects at any aperture value. The shooting module 2 and the lens system 3 are assembled together to realize the shooting function.
[0078] like Figure 2The specific structure of the lens system 3 in the photographing device of the present embodiment 1 is shown, which includes a lens module 4 and an electrical connector 5 mounted on the lens module 4; wherein the lens module 4 is the core component in the lens system 3, which plays a role of image taking, imaging and adjusting lens parameters; the electrical connector 5 plays a role of realizing electrical coupling and digital communication connection between the lens module 4 and the control system in the photographing device, which is mainly composed of a circuit connection substrate with FPC (Flexible Printed Circuit); the lens module 4 realizes intelligent electric control adjustment and digital control function through the electrical connector 5.
[0079] Specifically, the lens module 4 includes a protective film 6, a lens group 7, a focusing motor 8, a filter 9, an aperture 10 and an image sensor 11, along the optical axis direction of the lens module 4, the image sensor 11 is arranged between the filter 9 and the electrical connector 5, the focusing motor 8, the lens group 7 and the protective film 6 are sequentially arranged on the surface of the filter 9 away from the electrical connector 5, the image sensor 11 is connected to the electrical connector 5, wherein the protective film 6 is used to protect the lens module 4 from external dust or external force, the lens group 7 is used for imaging, the focusing motor 8 is used for focusing and zooming, the filter 9 is used for filtering light, the aperture 10 is used for adjusting the entering light and the depth of field, the image sensor 11 is used for receiving images, and the whole lens module 4 is used to form photos with different effects according to the user's needs. The aperture 10 can be arranged at any suitable position in the lens module 4, but the central axis of the aperture 10 needs to coincide with the optical axis X. The aperture 10 is connected to the electrical connector 5 and is powered through the electrical connector 5, so as to realize intelligent electric control adjustment and digital control of the aperture size, so that the user can realize taking photos with different effects at any aperture value.
[0080] Referring to Figures 3 to 5In the present embodiment 1, the aperture 10 arranged in the lens module 4 comprises a first conductive layer 12, a second conductive layer 13, an electrochromic layer 14, an ion storage layer 15 and an electrolyte layer 16, which are sequentially connected; the first conductive layer 12 and the second conductive layer 13 are respectively connected to the positive and negative ends of the power supply circuit; when the power supply circuit is powered on, an electric field is formed between the first conductive layer 12 and the second conductive layer 13, and the electric field controls the movement of ions in the ion storage layer 15 between the ion storage layer 15 and the electrochromic layer 14; when the direction of the electric field is the first direction D1, the ions move to the electrochromic layer 14 through the electrolyte layer 16 and adhere to the electrochromic layer 14, causing the electrochromic layer 14 to change color and form the aperture 10; when the direction of the electric field is the second direction D2, the ions move away from the electrochromic layer 14 through the electrolyte layer 16 to the ion storage layer 15, causing the electrochromic layer 14 to change color and form the light transmission hole 17; wherein the light transmission hole 17 is located in the aperture 10, the first direction D1 is that the electrochromic layer 14 points to the ion storage layer 15, and the second direction D2 is opposite to the first direction D1.
[0081] Specifically, in combination with the five-layer structure of the aperture 10 in Figure 2 and Figure 3 , Figure 3 , the aperture 10 is arranged in the lens module 4. Figure 2The first conductive layer 12, the ion storage layer 15, the electrolyte layer 16, the electrochromic layer 14 and the second conductive layer 13 arranged in the optical axis direction of the middle lens module 4 in turn means that the first conductive layer 12 and the second conductive layer 13 are located at the outermost side, the ion storage layer 15, the electrolyte layer 16 and the electrochromic layer 14 are located between the first conductive layer 12 and the second conductive layer 13, the ion storage layer 15 is attached to the first conductive layer 12, the electrochromic layer 14 is attached to the second conductive layer 13, and the electrolyte layer 16 is located between the ion storage layer 15 and the electrochromic layer 14. The first conductive layer 12 and the second conductive layer 13 are connected to the positive and negative ends of the power supply circuit, and whether the first conductive layer 12 and the second conductive layer 13 are connected to the positive end or the negative end of the power supply circuit can be determined according to actual conditions or user needs or product types. In the first optional implementation, the first conductive layer 12 is connected to the positive end of the power supply circuit, and the second conductive layer 13 is connected to the negative end of the power supply circuit. When the power supply circuit is forwardly powered, the electric field is in the second direction D2, and when the power supply circuit is reversely powered, the electric field is in the first direction D1. In the second optional implementation, the first conductive layer 12 is connected to the negative end of the power supply circuit, and the second conductive layer 13 is connected to the positive end of the power supply circuit. When the power supply circuit is forwardly powered, the electric field is in the first direction D1, and when the power supply circuit is reversely powered, the electric field is in the second direction D2. The above two optional implementations can make the electrode arrangement of the aperture 10 not be limited, and whether the first conductive layer 12 and the second conductive layer 13 are connected to the positive end or the negative end of the power supply circuit only affects the logic between the electric field direction and the aperture size adjustment. Figure 3 Only the five-layer structure arrangement of the aperture 10 is shown, and other arrangement modes can be transformed according to Figure 3 the above first optional implementation, the technical solution of the above second optional implementation can be inferred from the technical solution of the first optional implementation, and the principle will not be repeated. In Figure 3 , from left to right, each layer is in turn the first conductive layer 12, the ion storage layer 15, the electrolyte layer 16, the electrochromic layer 14 and the second conductive layer 13, in combination with Figure 2 , the first conductive layer 12 and the second conductive layer 13 are respectively connected to the electrical connecting piece 5 and powered through the electrical connecting piece 5, the first conductive layer 12 and the ion storage layer 15 are arranged together to excite the ion movement in the ion storage layer 15, and the second conductive layer 13 and the electrochromic layer 14 are arranged together to make the ion attached to the electrochromic layer 14 stable on the electrochromic layer 14. It should be noted that Figure 3 In order to facilitate illustration, the size of each layer is enlarged, and in fact the thickness of each layer is very small, in the order of microns to millimeters, and the thinner the thickness of each layer structure of the aperture 10, the better.
[0082] In this embodiment 1, Figures 3 to 5 The disclosed aperture 10 uses the physical property of electric field controlling ion movement and the chemical property of chemical reaction between ions and electrochromic layer 14 to make electrochromic layer 14 transparent, which together realizes the adjustment of aperture size. This adjustment of aperture size is different from the mechanical adjustment method of the existing aperture 10. It does not need to consider the mechanical adjustment structure with the function of enlarging or reducing the light transmission hole 17. It only needs a plane that can be coated with five layers of materials to realize the adjustment of the aperture 10. On the one hand, it can save the process flow and assembly space of installing the aperture 10 with mechanical adjustment structure. On the other hand, it increases the flexibility of the installation position of the aperture 10. The aperture 10 can be coated on any plane perpendicular to the optical axis X in the lens module 4, or it can be coated on the transparent glass in advance, and then the transparent glass and other components of the lens module 4 are installed together.
[0083] Referring to Figure 4 In one embodiment of the aperture 10 of this embodiment 1, the electrochromic layer 14 includes a carrier 18 and a plurality of color-changing rings 19 formed by color-changing materials coated on the carrier 18. The plurality of color-changing rings 19 are concentric rings with a common center O1. Different color-changing rings 19 correspond to different aperture values with respect to the inner diameter of the center O1. In the radial direction outward from the center O1, an electric field in the second direction D2 is applied to each color-changing ring 19 in turn from the color-changing ring 19.1 containing the center O1, and ions are sequentially detached from each color-changing ring 19. In the reverse direction of the radial direction, an electric field in the first direction D1 is applied to each color-changing ring 19 in turn from the outermost color-changing ring 19.2, and ions are sequentially attached to each color-changing ring 19. Specifically, the plurality of color-changing rings 19 do not completely realize full coverage of the aperture value. There are still a few parts of the aperture value that are not covered, because there will be a small gap 20 between each color-changing ring 19 that is not coated with color-changing material. However, overall, it basically realizes the function of arbitrary adjustment of aperture value. The more the number of color-changing rings 19, the more the change of aperture size that can be realized. The color-changing rings 19 can change color one by one from the center O1 to the edge or from the edge to the center O1, or they can change color simultaneously. The density of the color-changing rings 19 and the size of each color-changing ring 19 can be set according to the requirements. When adjusting the size of the aperture 10, the color-changing ring 19 corresponding to the aperture value that needs to be adjusted and the color-changing ring 19 inside it can be colored, and the aperture 10 has high accuracy in adjustment, realizing the function of arbitrary adjustment of aperture value. In terms of electrical connection process, the color-changing material coating method of the plurality of color-changing rings 19 can be more conducive to the electrical coupling between the electrochromic layer 14 and the second conductive layer 13. After all, only the corresponding aperture value size and position of different color-changing rings 19 need to be arranged corresponding traces at the corresponding position of the second conductive layer 13. The carrier 18 can be glass or a film.
[0084] Referring to Figure 5 In another embodiment of the aperture 10 of the present embodiment 1, the electrochromic layer 14 includes a carrier 18 and a color-changing region 21 formed by a color-changing material coated on the carrier 18, the color-changing region 21 contains a physical center O2 of the carrier 18, which can or can not be the center O1 of the circle; in the outward direction from the physical center O2, the ions gradually detach from the color-changing region 21 inwardly from the physical center O2; when the electric field intensity increases, the ions gradually diffuse outwardly from the physical center O2 and adhere to the color-changing region 21 in the reverse direction of the outward direction. Specifically, the electrochromic layer 14 has only one color-changing region 21 entirely coated with the color-changing material, and the physical center O2 of the color-changing region 21 is located on the optical axis X of the lens module 4. When the user starts adjusting the aperture 10, the ions are excited to move and adhere to the physical center O2 of the electrochromic layer 14, and the intermediate part of the electrochromic layer 14 changes color to form the aperture 10 through the chemical reaction between the ions and the color-changing material. When the ions detach from the electrochromic layer 14, the intermediate part of the electrochromic layer 14 changes to be transparent through the chemical reaction between the ions and the color-changing material, forming the light transmission hole 17. As the area where the voltage is applied in the color-changing region 21 converges from the edge of the color-changing region 21 to the physical center O2 of the color-changing region 21, the ions adhering to the electrochromic layer 14 gradually increase from the edge of the color-changing region 21 to the physical center O2, and the inner diameter of the light transmission hole 17 gradually decreases, so the aperture value also slowly decreases. As the area where the voltage is applied in the color-changing region 21 diffuses from the physical center O2 of the color-changing region 21 to the edge of the color-changing region 21, the ions adhering to the electrochromic layer 14 gradually decrease from the physical center O2 of the color-changing region 21 to the edge, and the inner diameter of the light transmission hole 17 gradually increases, so the aperture value also slowly increases. The design of the entire color-changing region 21 can completely realize the full coverage of the aperture value, and realize the function of arbitrary adjustment of the aperture value. In the process of gradually converging or diffusing the area where the voltage is applied in the color-changing region 21, the rate of the decrease or increase of the inner diameter of the light transmission hole 17 depends on the rate of the convergence or diffusion of the area where the voltage is applied, which is usually uniform. Because for the user experience, the change rate of the aperture 10 during shooting should not be too fast or too slow, which will affect the actual operation experience of the user. However, the design of the entire color-changing region 21 will make the electrical connection process more complex, which needs to additionally design a set of electrical control logic suitable for the mutual reaction of the ions and the color-changing material in the color-changing region 21 to realize the process of diffusing from the physical center O2 of the color-changing region 21 to the edge or converging from the edge of the color-changing region 21 to the physical center O2. The carrier 18 can be glass or a film.
[0085] In the present embodiment 1, the first conductive layer 12 and the second conductive layer 13 of the aperture 10 are both provided with indium tin oxide (ITO) traces, so that the first conductive layer 12 and the second conductive layer 13 have high transparency and do not affect imaging. The aperture 10 is connected with the FPC in the electrical connector 5 through the indium tin oxide traces, and then connected with the master control device in the shooting module 2 through the FPC, and the voltage of the indium tin oxide traces of the first conductive layer 12 and the second conductive layer 13 is controlled by the master control device to realize the color change of different apertures 10, so as to realize the control of the shooting device on different aperture sizes.
[0086] In combination Figure 4 and Figure 5 In the present embodiment 1, the ions stored in the ion storage layer 15 of the aperture 10 can be lithium ions for example, and the color-changing material coated in the electrochromic layer 14 can be tungsten trioxide (WO3) for example. When the user needs to adjust the aperture value of the aperture 10 to become smaller, the power supply circuit is controlled to supply power to the second conductive layer 13 through the electrical connector 5, that is, a voltage with the electric field direction being the first direction D1 is applied to both ends of the aperture 10, at this time, the lithium ions stored in the ion storage layer 15 enter the electrolyte layer 16 along the second direction D2 opposite to the electric field direction under the action of the electric field and move to the electrochromic layer 14, and finally adhere to the electrochromic layer 14. At this time, the lithium ions are injected into the tungsten trioxide, a chemical reaction occurs, and tungsten bronze LiWO3-x is formed, W 6+ is reduced to W 5+ , and the electronic transition absorbs photons to cause the glass / film to change color, so that in each color-changing ring 19 on the electrochromic layer 14, starting from the outermost color-changing ring 19.2, the color-changing rings 19 are sequentially changed to be opaque in the reverse radial direction to form the aperture 10, or starting from the outermost color-changing ring 19.3 within the inner diameter range of the light transmission hole 17, the color-changing rings 19 are sequentially changed to be opaque in the reverse radial direction to gradually reduce the light transmission hole 17, or starting from the edge of the color-changing area 21 of the electrochromic layer 14, the color-changing area 21 is gradually changed to be opaque in the reverse radial direction to form the aperture 10, or starting from the edge of the light transmission hole 17, the color-changing area 21 is gradually changed to be opaque in the reverse radial direction to gradually reduce the light transmission hole 17. When the user needs to adjust the aperture value of the aperture 10 to become larger, the power supply circuit is controlled to supply power to the first conductive layer 13 through the electrical connector 5, that is, a voltage with the electric field direction being the second direction D2 is applied to both ends of the aperture 10, at this time, the lithium ions in the electrochromic layer 14 are separated from the electrochromic layer 14 under the action of the electric field, enter the electrolyte layer 16 and move to the ion storage layer 15, and finally return to the ion storage layer 15. At this time, the tungsten bronze LiWO3-x undergoes a chemical reaction, and the lithium ions are separated from the tungsten bronze LiWO3-x, W 5+ becomes W 6+, the electronic transition absorption photon makes the glass / film discolor, so that in each discoloring ring 19 on the electrochromic layer 14, from the discoloring ring 19.1 containing the center, the discoloring ring 19.1 is sequentially discolored to transparent in the radial direction, forming a transparent light transmission hole 17, or from the most edge discoloring ring 19.3 in the inner diameter range of the light transmission hole 17, the discoloring ring 19.3 is sequentially discolored to transparent in the radial direction, so that the light transmission hole 17 gradually becomes larger, or from the physical center O2 of the discoloring area 21 of the electrochromic layer 14, the discoloring area 21 is gradually discolored to transparent in the radial direction, forming a transparent light transmission hole 17 in the aperture 10, or from the edge of the light transmission hole 17, the light transmission hole 17 is gradually discolored to transparent in the radial direction, so that the light transmission hole 17 gradually becomes larger.
[0087] In this embodiment 1, as shown in the drawings, Figure 6 The filter 9 of the lens module 4 has a filter glass 22, and the aperture 10 with the five-layer structure described above is coated on the filter glass 22, which can be coated on the surface of the filter glass 22 close to the image sensor 11 or on the surface of the filter glass 22 close to the focusing motor 8, and is used to filter light rays of specific wavelengths in natural light to form photos with different light and shadow effects. When the number of filter glasses 22 is two, the aperture 10 is arranged between the two filter glasses 22, that is, the aperture 10 with the five-layer structure is coated between the two filter glasses 22 to strengthen the structural stability of the aperture 10. The first conductive layer 12 of the aperture 10 can be coated on the filter glass 22 close to the image sensor 11 or on the filter glass 22 close to the focusing motor 8, and the second conductive layer 13 is the same. Of course, in other embodiments, the aperture 10 can also be made into a packaged glass layer alone, and the aperture 10 can be arranged in the lens group 7, or between the lens group 7 and the focusing motor 8, or between the focusing motor 8 and the filter 9, or between the filter 9 and the image sensor 11, etc., as long as the functions and technical effects of the aperture 10 in this embodiment 1 can be achieved.
[0088] Embodiment 2
[0089] The embodiment 2 of the present application discloses an aperture adjusting method applied to the photographing device disclosed in the embodiment 1 of the present application, and the photographing device has the lens system and the aperture disclosed in the embodiment 1 of the present application.
[0090] As shown in the drawings, Figure 7 The aperture adjusting method comprises:
[0091] S100: receiving a first operation of a user on the photographing device; and then performing S200.
[0092] S200: in response to the first operation, judging a selection of the user for adjusting the aperture; and then judging the selection of the user.
[0093] When the user selects to adjust the aperture to be smaller, S300 is performed: a voltage is applied to the aperture to make the direction of the electric field of the aperture be the first direction; when the user selects to adjust the aperture to be larger, S400 is performed: a voltage is applied to the aperture to make the direction of the electric field of the aperture be the second direction; wherein the first direction is that the electrochromic layer of the aperture points to the ion storage layer, and the second direction is opposite to the first direction.
[0094] Specifically, in S100, the user performs a first operation on the photographing device, which is that the user gives an instruction to the photographing device through a mobile device or a human-computer interaction function (such as a touch screen or an operation interface) of the photographing device, and selects to use the photographing device in large aperture adjustment or small aperture adjustment. At this time, the aperture in the photographing device can be closed, or can be the aperture value adjusted in the last use. Therefore, S200 needs to be performed to compare the aperture value selected by the user with the aperture value in the last use in response to the first operation of the user. If the aperture value selected by the user is smaller, small aperture adjustment is selected, and S300 is performed. If the aperture value selected by the user is larger, large aperture adjustment is selected, and S400 is performed. When S300 is performed, the control system of the mobile terminal or the photographing device controls the voltage applied to both ends of the aperture to make the direction of the electric field of the aperture be the first direction. At this time, the variable color material in the aperture gradually or instantaneously changes from the edge of the light transmission hole to the center or the physical center of the aperture to become non-transparent, so that the light transmission hole becomes smaller or even disappears, thereby realizing the small aperture effect. When S400 is performed, the control system of the mobile terminal or the photographing device controls the voltage applied to both ends of the aperture to make the direction of the electric field of the aperture be the second direction. At this time, the variable color material in the aperture gradually or instantaneously changes from the center or the physical center of the aperture or the edge of the light transmission hole to the edge of the aperture to become transparent, forming a light transmission hole or making the light transmission hole further larger, thereby forming the large aperture effect.
[0095] By using the aperture adjustment method of this embodiment 2, the direction of the electric field is controlled, the amount and position of the chemical reaction of the ions and the variable color material are controlled, and then the size of the light transmission hole formed in the aperture due to the color change of the variable color material is controlled, thereby realizing the effect of full coverage of the aperture value of the aperture size adjustment. This can help the user to take more photos with different effects and enhance the user's shooting experience.
[0096] In this embodiment 2, when the electrochromic layer of the aperture includes a carrier and a plurality of variable color rings formed by the variable color material coated on the carrier, the plurality of variable color rings are concentric rings with a common center, and the inner diameters of different variable color rings about the center correspond to different aperture values, respectively.
[0097] Optionally, when the aperture adjustment is getting larger, gradually apply voltage to each color-changing ring in the radial direction from the center to the outside, so that the electric field is in the second direction, until the aperture reaches the preset aperture value; when the aperture adjustment is getting smaller, gradually apply voltage to each color-changing ring in the reverse direction of the radial direction, so that the electric field is in the first direction, until the aperture reaches the preset aperture value or returns to the default aperture value or is completely closed. By sequentially applying voltage to each color-changing ring in the radial direction from the center to the outside, so that the electric field is in the second direction, the large aperture adjustment is realized, or by sequentially applying voltage to each color-changing ring in the reverse direction of the radial direction from the edge of the light transmission hole, the small aperture adjustment is realized. The function of aperture adjustment is realized by sequentially applying voltage to the color-changing ring corresponding to the position to make it change color layer by layer.
[0098] Optionally, according to the aperture size of the light transmission hole corresponding to the preset aperture value, voltage is applied to the color-changing ring in the aperture size range. The user can input the required aperture value in advance to form a preset aperture value, and then directly apply voltage to all color-changing rings in the aperture size range of the light transmission hole corresponding to the preset aperture value during adjustment. When the applied voltage makes the electric field of the aperture in the first direction, the small aperture adjustment of the aperture is realized. When the applied voltage makes the electric field of the aperture in the second direction, the large aperture adjustment of the aperture is realized. The function of aperture adjustment is realized by simultaneously applying voltage to the color-changing ring corresponding to the position in the aperture size range of the light transmission hole corresponding to the preset aperture value.
[0099] It can be understood that part or all of the steps or operations in the above embodiments are only examples, and the embodiments of the present application can also perform other operations or various modifications of the operations. In addition, each step can be executed in a different order from the above-mentioned embodiments, and it is possible that not all the operations in the above-mentioned embodiments are executed.
[0100] Further, generally, it can be clear to distinguish whether an improvement of a technology is in hardware (e.g., improvement of circuit structure of diode, transistor, switch, etc.) or in software (e.g., improvement of method flow). However, as technology develops, many improvements of method flow nowadays can be considered as direct improvement of hardware circuit structure. Designers almost always program improved method flow into hardware circuit to get corresponding hardware circuit structure. Therefore, it cannot be said that an improvement of method flow cannot be implemented by hardware entity module. For example, Programmable Logic Device (PLD) (e.g., Field Programmable Gate Array (FPGA)) is such an integrated circuit, whose logic function is determined by accessing party programming the device. A digital device is "integrated" on a piece of PLD by designers programming it by themselves, without asking chip manufacturers to design and make special integrated circuit chip. Moreover, nowadays, instead of manually making integrated circuit chip, such programming is mostly implemented by "logic compiler" software, which is similar to software compiler used when programming is developed and written, and the original code before being compiled also needs to be written in specific programming language, which is called hardware description language (HDL), and there are many kinds of HDL, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., and the most commonly used are VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also be clear that only a little logical programming of method flow in the above-mentioned hardware description languages and programming into integrated circuit can easily get hardware circuit implementing the logical method flow.
[0101] Therefore, the method flow proposed in the embodiments of the present application can be implemented in a hardware manner, for example, using a controller to control a touch screen to implement the method flow proposed in the embodiments of the present application.

[0103] The present application provides a computer readable storage medium, the computer readable storage medium stores a computer program, when the computer program is run on a computer, the computer executes the aperture adjustment method disclosed in Embodiment 2 of the present application.
[0104] The present application provides a computer program product, the computer program product comprises a computer program, when the computer program is run on a computer, the computer executes the aperture adjustment method disclosed in Embodiment 2 of the present application.
[0105] Those skilled in the art can clearly understand that the technologies in the embodiments of the present application can be realized by means of software and necessary general hardware platforms. Based on such understanding, the technical solutions in the embodiments of the present application can be embodied in the form of software products, which can be stored in storage media such as ROM / RAM, magnetic disks, optical disks, etc., and include a plurality of instructions for causing a computer device (which can be a personal computer, a server, or a network device, etc.) to execute the methods described in the various embodiments or some parts of the embodiments of the present application.
[0106] According to the aperture, the aperture adjustment method, the lens system, the photographing device and the mobile device provided in the embodiments of the present application, a voltage is applied to the color-changing material, the color-changing material and ions react chemically to make the electrochromic layer change color and become transparent, forming a light-transmitting hole capable of transmitting light, the size of the light-transmitting hole is changed by changing the direction and size of the voltage, the aperture size is more smoothly adjusted, and the lens system can take more different effect photos under the condition of more sizes of apertures.
