Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative and are only for the purpose of explaining the present application and are not to be construed as limiting the present application.

Referring to fig. 1 to 3, a lens assembly 10 according to an embodiment of the present disclosure includes a lens group 12 and a prism 14. The prism 14 comprises an entrance face 142, a reflection face 144 and an exit face 146, at least one of the entrance face 142 and the exit face 146 being provided with an electrochromic structure 16. The prism 14 is used for projecting the light incident from the incident surface 142 to the lens group 12 from the exit surface 146 after being reflected by the reflecting surface 144.

The periscopic camera 100 according to the embodiment of the present application includes the lens assembly 10 according to the embodiment of the present application and the image sensor 20. The image sensor 20 is arranged on a side of the lens group 12 remote from the prism 14.

The electronic apparatus 1000 according to the embodiment of the present application includes the rear cover 200 and the periscopic camera 100 according to the embodiment of the present application. The periscopic camera 100 is exposed from the rear cover 200.

In the lens assembly 10, the periscopic camera 100 and the electronic device 1000 according to the embodiment of the present application, the electrochromic structure 16 is disposed on the incident surface 142 and/or the exit surface 146 of the prism 14 of the lens assembly 10, and the light is selected by coloring the electrochromic structure 16, so that the lens assembly 10 can achieve a physical filter effect, avoid image distortion caused by image algorithm processing, reduce resources occupied by the image algorithm on the electronic device 1000, and improve user experience.

In some embodiments, the electronic device 1000 includes a cell phone, a tablet, a laptop, a smart band, a wearable device, and the like. In the illustrated embodiment, the electronic device 1000 is a cell phone.

It will be appreciated that the electrochromic structure 16 may undergo a reversible color change under the influence of an electric field, wherein the electrochromic structure 16, in a colored state, exhibits a color with a high transmittance of light at wavelengths corresponding to the color exhibited, and a lower transmittance of light at wavelengths corresponding to other colors. Therefore, the electrochromic structure 16 can realize the function of light selective filtering in a colored state, in the lens assembly 10, the light is selected before imaging by controlling the electrochromic structure 16 to realize a physical filter effect, and the light can realize corresponding focal length and field of view through the lens group 12, so that the image sensor 20 can collect corresponding image signals and provide images of original negative films with corresponding styles for user imaging.

In some embodiments, electrochromic structure 16 may be formed on the surface of prism 14 by way of a coating.

Specifically, referring to fig. 4, the electrochromic structure 16 includes a first transparent conductive layer 1612, an electrochromic layer 162, an electrolyte layer 163, an ion storage layer 164, and a second transparent conductive layer 1614, which are sequentially stacked. Wherein the first transparent conductive layer 1612 and the second transparent conductive layer 1614 form an electrode pair 161 of the electrochromic structure 16, the first transparent conductive layer 1612 is electrically connected to the electrochromic layer 162, and the second transparent conductive layer 1614 is electrically connected to the ion storage layer 164, that is, the electrochromic structure 16 includes the electrode pair 161, and the electrochromic layer 162, the electrolyte layer 163, and the ion storage layer 164 sequentially stacked between the electrode pair 161.

Thus, the electrochromic structure 16 is in a neutral state when no voltage is applied, and at this time, the electrochromic material is basically in a transparent state, the light transmittance is high, visible light can be completely transmitted, and a normal image effect can be obtained when an image is shot. When a voltage is applied to the electrochromic structure 16, the electrolyte layer 163 reversibly reacts under the action of an electric field, so that ions migrate to the electrochromic layer 162 to change the transmittance of the electrochromic layer 162, thereby forming a colored state. Wherein the electrochromic structure 16 applies a voltage, i.e. a voltage to the electrode pair 161, so that the electrochromic layer 162 is colored.

In some embodiments, the transmittance of the electrochromic structure 16 in the transparent state may be greater than 75%, and the electrochromic structure 16 may maintain good optical properties in the transparent state. The transmittance in the colored state is more than 40%, and the electrochromic structure 16 can keep effective light transmission after being colored, so that the image sensor 20 can realize normal imaging.

In some embodiments, the first transparent conductive layer 1612 and the second transparent conductive layer 1614 can be Indium Tin Oxide (ITO), which has excellent conductivity and good optical transmittance without affecting the optical transmittance of the device.

Of course, in other embodiments, the first transparent conductive layer 1612 and the second transparent conductive layer 1614 may also be tin oxide (SnO2), Antimony Tin Oxide (ATO), or gold (Au), silver (Ag) nanowires, or the like. The transparent conducting layer can be prepared on a transparent substrate such as glass, plastic and the like in a magnetron sputtering mode. In this way, the electrochromic structure 16 may maintain good optical properties in the transparent state.

In certain embodiments, the electrochromic layer 162 is made of an electrochromic material, and the electrochromic material includes an inorganic electrochromic material or a conductive polymer.

The inorganic electrochromic material can be plated on the transparent conductive layer by means of an electron beam evaporation method, an electrochemical deposition method or the like, and the conductive polymer can be attached on the transparent conductive layer by means of a spin coating method, a spraying method, an electrochemical polymerization method or the like.

In certain embodiments, the electrochromic material comprises an anodic electrochromic material or a cathodic electrochromic material.

Specifically, the anodic electrochromic material is in a transparent or light-colored state in a neutral state and in a colored state in an oxidized state. The cathode electrochromic material is in a colored state in a neutral state and is in a transparent or light-colored state in a doped state.

In one example, the anodic electrochromic material may be nickel oxide (NiO) and the cathodic electrochromic material may be poly (3, 4-ethylenedioxythiophene) (PEDOT).

It should be understood that different electrochromic materials can exhibit different colors under the action of the electric field under the condition that the voltage is applied to the electrochromic structure 16, so that the electrochromic structure 16 can select a suitable electrochromic material according to actual needs and enable the electrochromic structure 16 to exhibit a desired color through corresponding voltage control.

In certain embodiments, the electrochromic material comprises a dual electrochromic material. The dual electrochromic materials may allow the entire electrochromic structure 16 to display color in both the oxidized and reduced states by controlling the voltage applied to the electrode pairs 161.

Note that the dual electrochromic material means that the dual electrochromic material can take different colors in the case where different voltages are applied to the electrode pair 161. In one example, the dual electrochromic material exhibits one color in the oxidized state and another color in the reduced state.

In some embodiments, upon application of a first voltage and a second voltage to the electrode pair 161, the dual electrochromic material exhibits different colors, the first voltage being opposite in polarity to the second voltage.

It is understood that the first voltage may be a forward voltage and the second voltage may be a reverse voltage of the first voltage, such that the dual electrochromic material is in an oxidized state and exhibits one color when the forward voltage is applied to the electrode pair 161; in the case where a reverse voltage is applied to the electrode pair 161, the dual electrochromic material is in a reduced state, exhibiting another color.

In addition, the application of the forward voltage to the electrode pair 161 may be performed such that the first transparent conductive layer 1612 is connected to a positive power supply electrode and the second transparent conductive layer 1614 is connected to a negative power supply electrode.

In certain embodiments, the ion storage layer 164 is used to store the corresponding counter ions when the oxidation-reduction reaction of the electrochromic material occurs.

In this manner, the electrochromic structure 16 may be charge balanced as a whole in cooperation with the corresponding circuitry. For example, when positive ions are transferred to the electrochromic layer 162 under the action of an electric field, negative ions may be transferred to the ion storage 164 for storage, or when negative ions are transferred to the electrochromic layer 162 under the action of an electric field, positive ions may be transferred to the ion storage 164 for storage.

In certain embodiments, the ion storage layer 164 may be another electrochromic material having properties opposite to the electrochromic material of the electrochromic layer 162.

Referring to fig. 5, that is, the electrochromic structure 16 includes a first electrochromic layer 1622, an electrolyte layer 163, and a second electrochromic layer 1624 sequentially stacked between the pair of electrodes 161, and the electrochromic material of the first electrochromic layer 1622 has a property opposite to that of the electrochromic material of the second electrochromic layer 1624.

It should be noted that the opposite property may be the opposite property of the electrochromic material in the oxidized state and the reduced state, for example, one electrochromic material is in the colored state in the oxidized state and the other electrochromic material is in the transparent state in the oxidized state.

Thus, when a voltage is applied, the electrochromic materials of the first electrochromic layer 1622 and the second electrochromic layer 1624 are in opposite oxidation states or reduction states, and the first electrochromic layer 1622 and the second electrochromic layer 1624 can be in coloring states at the same time, so that the electrochromic structure 16 realizes color superposition or complementation, and meets more color requirements.

Of course, in other embodiments, the ion storage layer 164 may be made of a material that is only used to store charges and does not have electrochromic properties, and is not particularly limited herein.

In some embodiments, the prism 14 may be a triangular prism 14, with the entrance face 142 and the exit face 146 being perpendicular to each other.

Thus, the prism 14 can reflect the incident light and emit the light to the lens assembly 12 along the direction perpendicular to the incident direction of the light, and the lens assembly 12 and the prism 14 can be arranged in parallel, so as to reduce the stacking of the lens assembly 10 in the incident direction of the light, which is beneficial to optimizing the spatial configuration of the lens assembly 10.

Further, the lens group 12 with the optical axis perpendicular to the light incidence direction can have a large space for arranging the positions of the respective lenses to achieve the functions of condensing, zooming, and changing the angle of field while ensuring a small thickness dimension.

Referring again to fig. 3, in some embodiments, the entrance face 142 of the prism 14 is provided with the electrochromic structure 16.

In this way, by controlling the coloring of the electrochromic structure 16, so that the electrochromic structure 16 can select before the light enters the prism 14, the transmittance of light with wavelengths corresponding to other colors than the color displayed by the electrochromic structure 16 is reduced, so that the light entering the lens set 12 can realize a physical filter effect.

Referring to fig. 6, in some embodiments, the exit face 146 of the prism 14 is provided with an electrochromic structure 16.

Similarly, by controlling the coloring of the electrochromic structure 16 so that the electrochromic structure 16 selects the light after the light exits from the exit surface 146, the transmittance of light with wavelengths corresponding to other colors than the color displayed by the electrochromic structure 16 is reduced, so that the light entering the lens assembly 12 can realize a physical filter effect.

Referring to fig. 7, in some embodiments, the entrance face 142 and the exit face 146 of the prism 14 are provided with electrochromic structures 16.

In particular, the entrance face 142 is provided with a first electrochromic structure 165 and the exit face 146 is provided with a second electrochromic structure 166. In this way, different light selection effects can be achieved by controlling the first electrochromic structure 165 and the second electrochromic structure 166 for combined coloring.

In certain embodiments, the first electrochromic structure 165 and the second electrochromic structure 166 may be independently controlled. The first electrochromic structure 165 and the second electrochromic structure 166 exhibit different colors in the colored state.

In this manner, by individually controlling the coloration of one of the electrochromic structures 16, different colors of light may be selected. And the two electrochromic structures 16 are controlled to be colored simultaneously, so that different colors can be superposed, and the filter effect of the electrochromic structures 16 is enriched.

In certain embodiments, first electrochromic structure 165 and second electrochromic structure 166 may be different regions of the same electrochromic structure 16. That is, a portion of the electrochromic structure 16 is disposed at the entrance face 142 of the prism 14 and another portion is disposed at the exit face 146 of the prism 14.

In this way, the combination and superimposition of the colors of the electrochromic structure 16 after coloring can also be achieved by controlling the different regions of the electrochromic structure 16.

It should be noted that, in the description of the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features.

The lens assembly 10 changes the direction of light transmission through the prism 14, the electrochromic structure 16 is arranged on the incident surface 142 and the exit surface 146 of the prism 14 to realize light selection, and meanwhile, the surface of the prism 14 is a smooth plane, so that the electrochromic material is easily formed on the surface of the prism 14 through film coating.

Referring to fig. 8, in some embodiments, periscopic camera 100 may further include a control system 30 and a voltage system 40, where control system 30 is configured to control voltage system 40 to apply a voltage to electrode pairs 161 of electrochromic structure 16 to color or fade electrochromic structure 16.

When the voltage applied to the electrode pair 161 of the electrochromic structure 16 is within a certain range, the transmittance of the electrochromic structure 16 may change with the change of the voltage. In this way, by precisely controlling the polarity and magnitude of the voltage applied to the electrochromic structure 16 by the control system 30, the color of the electrochromic structure 16 and the transmittance of the electrochromic structure 16 can be controlled, thereby obtaining a desired filter effect.

In some embodiments, the periscopic camera 100 includes a housing 50 and a cover plate 60, the housing 50 defines a light hole 52, and the cover plate 60 is disposed in the light hole 52 and corresponds to the incident surface 142.

Wherein the lens assembly 10 and the image sensor 20 are disposed within the housing 50. In this manner, the housing 50 can protect the lens assembly 10 and can reduce interference of external unwanted ambient light with the imaging of the image sensor 20. In addition, the housing 50 may provide support for various components of the lens assembly 10, ensuring that the periscopic camera 100 operates properly.

In some embodiments, a third electrochromic structure 167 is disposed on the cover 60.

In this way, the third electrochromic structure 167 on the cover plate 30 can form a colored combination with the electrochromic structure 167 on the prism, thereby realizing a richer filter effect.

In one example, the third electrochromic structure 167 may form a colored combination with the electrochromic structure 16 disposed on the incident face 142; or in colored combination with the electrochromic structure 16 disposed on the exit face 146; or in colored combination with a first electrochromic structure 165 disposed on the entrance face 142 and a second electrochromic structure 166 disposed on the exit face 146.

It can be understood that the cover plate 30 is disposed at the light-passing hole 52, and can play a role of protection together with the housing 50 while achieving light transmission, so as to prevent dust and impurities from entering the interior of the periscopic camera 100. At this time, the cover plate 30 is exposed to the environment and is easily damaged, so that the cover plate 30 may not be provided with an electrochromic structure to reduce the influence of environmental factors (e.g., external force, electrostatic effect, moisture erosion, etc.) on the electrochromic structure. The lens assembly 10 is provided with the electrochromic structure 16 at the prism 14, and in this case, the electrochromic structure 16 is located inside the housing 50, and the housing 50 can protect the electrochromic structure 16 from the external environment.

In some embodiments, the cover 60 may be an infrared filter cover 60.

Thus, the periscopic camera 100 can filter the infrared rays through the infrared filtering cover plate 60, reduce the interference of the infrared rays on the imaging of the image sensor 20, and improve the imaging quality.

Of course, in other embodiments, the periscopic camera 100 may filter the infrared light through a separate infrared cut filter (not shown). The ir-cut filter may be disposed on an optical path in the housing 50, for example, between the cover plate 60 and the prism 14, between the prism 14 and the lens group 12, or between the lens group 12 and the image sensor 20, which is not limited herein.

In some embodiments, periscopic camera 100 may optimize the image captured by image sensor 20 via an image algorithm.

It will be appreciated that when the electrochromic structure 16 is disposed on the prism 14, problems such as refraction, reflection, and diffraction may occur during light transmission due to the different materials between the electrochromic structure 16 and the prism 14. In this way, the periscopic camera 100 can optimize the image captured by the image sensor 20 through an image algorithm, thereby preventing image distortion.

In particular, in some embodiments, for the case of multiple color filter effects, periscopic camera 100 may select a corresponding algorithm to optimize the image captured by image sensor 20 based on the coloring of electrochromic structure 16.

Because the refractive index when different light is transmitted in the medium is different, and electrochromic structure 16 is colored, electrochromic structure 16 presents the light transmissivity that the color corresponds high, and the light transmissivity that other colors correspond is lower, that is to say, under the different colour filter effects, in the light through electrochromic structure 16, the light that each color corresponds constitutes differently. Therefore, according to the coloring condition of the electrochromic structure 16, for example, the coloring color of the electrochromic structure 16, a corresponding algorithm can be selected to optimize the image collected by the image sensor 20, thereby further preventing image distortion and improving the imaging effect.

It should be noted that the periscopic camera 100 may optimize the image and transmit the image to the electronic device 1000 for storage, display or sharing. In other embodiments, the periscopic camera 100 may further transmit the image captured by the image sensor 20 to the electronic device 1000, and then the electronic device 1000 optimizes the image, which is not limited in this respect.

The periscopic camera 100 employs the lens assembly 10, and can change the light propagation direction through the prism 14, reducing the stacking of lens elements in the light incidence direction, so that the lens assembly 12 has a larger arrangement space in the direction perpendicular to the light incidence direction. The periscopic camera 100 may act as a tele-camera.

Referring again to fig. 1, in some embodiments, electronic device 1000 includes wide-angle camera 300, where wide-angle camera 300 and periscopic camera 100 are arranged in parallel.

So, wide camera 300 and telephoto camera form two camera combinations, and electronic equipment 1000 can form images through two camera combinations to obtain better imaging.

Referring to fig. 9, the present embodiment provides a control method for controlling the electrochromic structure 16, the control method includes:

step S1: determining a target color for the electrochromic structure 16;

step S2, determining a target voltage according to the target color; and

in step S3, a target voltage is applied to the electrode pairs 161 to cause the electrochromic structure 16 to assume a target color.

Specifically, steps S1 and S2 may be implemented by the control system 30, and step S3 may be implemented by the voltage system 40. That is, the control system 30 may be used to determine a target color for the electrochromic structure 16, and to determine a target voltage based on the target color. The voltage system 40 may be used to apply a target voltage to the electrode pairs 161 to cause the electrochromic structure 16 to assume a target color.

The control method may accurately determine the target color and the target voltage applied to the electrochromic structure 16 by the control system 30, such that the voltage system 40 may control the color and transmittance of the coloration of the electrochromic structure 16 by controlling the applied voltage to achieve the desired filter effect.

Referring to fig. 10, in some embodiments, when the electrochromic structure 16 is colored, the transmittance of the electrochromic structure 16 corresponds to the voltage applied to the electrode pair 161 of the electrochromic structure 16, and the step S2 includes:

step S22, determining a target transmittance according to the target color; and

in step S24, the magnitude of the target voltage is determined based on the target transmittance.

Specifically, steps S22 and S24 may be implemented by the control system 30, that is, the control system 30 may be configured to determine the target transmittance according to the target color and determine the magnitude of the target voltage according to the target transmittance.

At this time, the control system 30 controls the amount of light transmitted through the electrochromic structure 16 by controlling the magnitude of the voltage applied to the electrode pair 161 to adjust the transmittance of the coloring of the electrochromic structure 16, thereby achieving different filter effects.

In some embodiments, the electrochromic structure 16 may exhibit different colors at different voltages, and step S2 includes: and determining the polarity and the magnitude of the target voltage according to the target color.

In particular, the control system 30 may be used to determine the polarity and magnitude of the target voltage based on the target color.

At this time, the control system 30 may adjust the color and transmittance of the coloration of the electrochromic structure 16 by controlling the polarity and magnitude of the voltage applied to the electrode pair 161.

In certain embodiments, step S1 includes: the target color of the electrochromic structure 16 is determined based on user input.

It will be appreciated that a user may select a desired filter effect to be photographed by entering an instruction so that the control system 30 determines the corresponding filter color and thereby controls the coloring of the corresponding electrochromic structure 16.

step S2, determining a target voltage according to the target color; and

The electronic device 1000 may determine the target color and the target voltage applied to the electrochromic structure 16 by the processor 400 executing corresponding computer programs, such that the voltage system 40 may control the color and transmittance of the coloring of the electrochromic structure 16 by controlling the applied voltage, thereby obtaining the desired filter effect
