A first aspect of the embodiments of the present disclosure provides a camera module 10, as shown in fig. 1, the camera module 10 includes a color changing element 11, a lens 12, and an image sensor 13, which are disposed along a light incident direction. Wherein the lens 12 acquires an image and images it on the image sensor 13. The image sensor 13 receives an optical signal based on imaging of the lens 12, and converts the received optical signal into a digital signal or an electrical signal.
In one embodiment, the camera module 10 includes a bottom plate 161 and a side wall 162 connected to each other, and a cavity 163 with one open side is formed by the bottom plate 161 and the side wall 162. The cavity 163 is used for accommodating the lens 12 and the image sensor 13.
Wherein the lens 12 includes at least one lens 121 and a lens mount 122. When a plurality of lenses 121 are included, the plurality of lenses 121 are mounted on the lens mount 122 in such a manner that optical axes thereof coincide. Also, the optional image sensor 13 is mounted on the lens mount 122 to maintain relative stability with the lens 121. An optional lens mount 122 is mounted on the base plate 161 to secure the lens 12. In addition, the bottom plate 161 may be a circuit board, such as a printed circuit board or a flexible circuit board, so that the camera module 10 can be connected with other components for use.
Optionally, the camera module 10 includes at least two lenses 12 covered by the color changing member 11. The lens 12 may include a wide-angle lens and a telephoto lens, among others, to switch the activation or synchronously activate to achieve a desired photographing effect. In addition, the number and arrangement of the image sensors 3 are not particularly limited. For example, at least two lenses 12 each have a corresponding image sensor 13, or at least two lenses 12 share one image sensor 13.
The color changing member 11 is disposed on the open side of the cavity 163 and covers the lens 12, so that incident light passes through the color changing member 11 and then is imaged on the image sensor 13 through the lens 12. The color-changing member 11 may achieve a transparent state as shown in fig. 3 or a colored state having a predetermined color as shown in fig. 4.
It is noted with respect to the colored state of the color changing member 11 that the preset color of the colored state may be a single color, such as red, yellow, blue, etc. Or, the preset color is a color group including multiple colors, and the multiple colors are presented in a preset manner to achieve effects such as gradient or preset patterns.
When the camera module 10 is started, the color changing piece 11 is in a transparent state, and the lens 12 acquires an image and forms an image on the image sensor 13. When the camera module 10 is closed, the image sensor 13 does not convert the electrical signal or the digital signal according to the received optical signal, and the color changing member 11 is in a colored state. It should be noted that the color-changing member 11 can change the transparent state and the colored state by changing the color, or changing the transparency, or changing the color and the transparency simultaneously. However, the color change element 11 should satisfy: the transparent state is higher in the transparent state than in the colored state, e.g., the colored state is a non-transparent state. Therefore, the camera module 10 can obtain clear images in a transparent state and can show a preset effect with the camera body in a colored state.
When the camera module 10 is assembled on the terminal device, the part of the color-changing piece 11 corresponding to the lens 12 is exposed, so that the light-transmitting hole of the body is in a preset color when the color-changing piece 11 is in a colored state. Specifically, the color of the part of the body of the terminal device provided with the camera module 10 surrounding the light hole is used as a preset color, and when the camera module 10 is closed, the color changing piece 11 exposed at the light hole is in the same color as the other parts of the body. Therefore, the difference between the light-transmitting hole of the machine body and other parts is weakened, and the machine body has an integrated and complete effect. Furthermore, the camera module 10 provided by the embodiment of the present disclosure provides a new feasible solution for presenting an expected effect to the body back plate of the terminal device, so as to meet the user requirements.
In one embodiment, the transparent state of the color changing member 11 may be selected to be a colorless transparent state or a colored transparent state. When the color-changing member 11 is in a colorless transparent state, the camera module 10 obtains an image with a normal color. When the color-changing piece 11 is in a colored transparent state, the color-changing piece can be used as a filter disc, so that the shooting effect of the camera module 10 is enriched. It should be noted that when the camera module 10 in the related art is used, the filter effect is usually realized by software processing. Therefore, the requirement on software is high, and the filter effect is difficult to realize due to overlarge operation amount when the video is shot. However, in this embodiment, the filter effect is realized by the color changing element 11, which not only reduces the requirement for software, but also helps to obtain video with filter effect.
With respect to the implementation of the color change member 11, in one embodiment, the color change member 11 comprises an electrochromic member. The electrochromic element can present different colors under the action of different electric fields. Moreover, the selectable color-changing piece 11 is formed by splicing different electrochromic pieces, and the color-changing piece 11 is locally changed in color by controlling different electrochromic pieces, or multiple colors are simultaneously presented, so that the shooting effect of the camera module 10 is enriched.
The above is only an exemplary embodiment, and the color changing member 11 may also adopt other implementation manners to switch between the transparent state and the colored state.
Optionally, the color changing member 11 has a film-like structure, and the camera module 10 further includes a transparent cover plate 14 disposed on a side of the lens 12 opposite to the image sensor 13, wherein the transparent cover plate 14 covers the lens 12. The transparent cover plate 14 closes the open side of the cavity 163, providing a safe and stable working space for the lens 12 and the image sensor 13. The color changing member 11 is provided over the transparent cover 14. The color changing element 11 is disposed on a side of the transparent cover 14 away from the lens 12, or the color changing element 11 is disposed on a side of the transparent cover 14 close to the lens 12. When the color changing piece 11 is arranged close to the lens 12, the transparent cover plate 14 also provides a guarantee for the color changing piece 11, and the color changing piece 11 is not directly exposed at the light-transmitting hole at the moment, so that damage is avoided.
In addition, the camera module 10 may include at least two stacked transparent cover plates 14, and the color changing member 11 is disposed on each transparent cover plate 14 to form the stacked color changing members 11. Furthermore, a superimposed color effect is achieved by the at least two color change members 11 being superimposed. In this way, the color choice that the color-changing member 11 finally presents can be enriched when only a single color can be realized by one color-changing member 11.
Wherein the transparent cover plate 14 can be a glass cover plate or a resin cover plate. The placement of the color changing member 11 is not particularly limited, and may cover the lens 12.
Further, the camera module 10 further includes a light emitting element 15, the light emitting element 15 and the lens 12 are located on the same side of the color changing element 11, and the color changing element 11 is covered by the light emitting element 15. It can be understood that the light emitted from the light emitting assembly 15 passes through the color changing element 11 and then exits the camera module 10. Optionally, the light emitting assembly 15 is a flash to improve the lighting conditions of the area being photographed when the image is acquired. At this time, the light emitting element 15 can achieve a colored flashing effect in cooperation with the colored transparent state of the color changing member 11. Or, the light emitting assembly 15 is a flashlight, and in this case, different lighting effects can be realized by matching the light emitting assembly 15 with the coloring state of the color changing member 11. For example, the color changing member 11 is in a transparent milky white color in the colored state, and the effect similar to ground glass is realized. At this time, the light emitting effect of the light emitting component 15 is soft, and the situation that strong light is dazzled when the light emitting component 15 is started in a dark environment is avoided.
