Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

In order to better understand the scheme of the embodiment of the present application, the following technical contents are first described:

(1) description of the spectra: light is one of the electromagnetic waves, and we tend to distinguish the different electromagnetic waves by wavelength. The units of wavelength are typically expressed in nm (nanometers). In the light (sunlight), a part visible to the naked eye is called "visible light", and the wavelength range of the visible light is about 380-780 nm. The parts other than this are invisible to the naked eye and are conventionally called "lines", such as infrared rays and ultraviolet rays. In the spectrogram, the ultraviolet light band is formed by the wavelengths below 380nm and the infrared light band is formed by the wavelengths above 780nm close to two ends of visible light.

(2) The spectral characteristics of the optical filter in the conventional RGB camera module mainly penetrate in the visible light band and are cut off in the infrared and ultraviolet portions, such characteristic settings are mainly to keep consistent with the photosensitive characteristics of human eyes, and the problem of color cast during photographing is avoided.

(3) Aiming at different photographing application requirements, an additional camera module can be added in the electronic device, the spectral characteristics of an Optical filter in the additional camera module are different from those of an Optical filter in a conventional RGB camera module, for example, the Optical filter in the additional camera module is highly transparent in a band interval of 680nm ± 20nm (namely 660nm to 700nm), and the transmittance curve of the Optical filter is shown in fig. 1b, wherein a solid line is the transmittance curve of the Optical filter at an Automatic Optical Inspection (AOI) tilt angle of 0 degree, and a dotted line is the transmittance curve of the Optical filter at an AOI tilt angle of 30 degrees, in a photograph taken by the additional camera module, original green vegetation and trees can be displayed as pink, so that a photographing effect like illusion is presented.

Based on the above description, it can be found that, in the prior art, in order to satisfy multiple photographing requirements, it is imperative to add an additional camera module in the electronic device, and the drawback brought by the newly added module is the increase of the material cost of the electronic device and the increase of the stacking difficulty of the whole structure.

Therefore, a solution that does not require an additional module while satisfying various photographing requirements is needed.

The following describes the camera module provided in the embodiments of the present application in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to fig. 2a, the embodiment of the present application provides a camera module, including lens 1, the camera module further includes: at least two resonant cavities 2;

above-mentioned camera lens 1 mainly plays transmission, refraction light's effect, and external light transmits the chip after the camera lens on, and the light signal is received to the chip, and then reaches the purpose of formation of image with light signal conversion for the signal of telecommunication.

Specifically, in some embodiments, the resonant cavity is a Fabry-Perot (F-P) cavity.

The two F-P cavities 2 are overlapped and arranged on the lens end surface of the lens 1, and taking the scene shown in fig. 2a as an example, at least two F-P cavities 2 are overlapped and arranged on the top end surface of the lens 1; fig. 2a shows a scenario comprising two F-P cavities 2, it being understood that a number of 3, 4 or more F-P cavities may be provided according to product requirements;

in the embodiment of the present application, an adjusting member (not shown in the drawings) for adjusting the thickness of the F-P chamber 2 is provided in the F-P chamber 2; in the case where the thickness of each F-P cavity 2 is the target thickness of each F-P cavity 2, only one transmission peak having the same wavelength is included between each F-P cavity 2.

In the embodiment of the application, at least two overlapped F-P cavities are added on the camera module, the thickness of each F-P cavity is adjusted to the target thickness of each F-P cavity, so that only one transmission peak with the same wavelength is included between each F-P cavity, the transmission peak with the same wavelength is only required to be corresponding to the target optical wavelength, only the light with the target optical wavelength can be obtained by the lens through the F-P cavity, and multiple photographing requirements can be met by one camera module.

The target optical wavelength refers to an optical wavelength corresponding to the selected photographing module, for example: when the photographing effect of photographing the green vegetation and the trees as pink is to be achieved, the thickness of each F-P cavity is adjusted, the transmission peak of the F-P cavity is within the transmission range shown in the figure 1b, so that the F-P cavity can only transmit light within the range, and only the light within the range can be acquired by the lens, and the photographing effect of photographing the green vegetation and the trees as pink is achieved. By adopting the camera module provided by the embodiment of the application, the thickness of the F-P cavity is correspondingly adjusted according to different photographing requirements, and the tuning of the wavelength of transmitted light is realized, so that various different filtering modes can be completed by only one camera module, and various different photographing requirements are realized.

With continued reference to fig. 2a, in some embodiments, the camera module further comprises:

the drive motor 3: the lens 1 is pushed to reach a corresponding position, so that the imaging focal plane is superposed with the photosensitive chip 5, the aim of clear imaging is fulfilled, and if the imaging focal plane of the lens is not superposed with the photosensitive chip 5, the imaging is fuzzy;

base (holder) 4: the function of structural support and carrying of the driving motor 3 is achieved;

the photosensitive chip 5: after receiving the optical signal transmitted to the inside of the module through the lens 1, the optical signal is converted into an electric signal through the processing inside the photosensitive chip 5;

circuit board 6: mainly the transmission function of electric signals.

The structure of each component may be the structure of a corresponding component in an existing camera module, which is not specifically limited in the embodiment of the present application.

It should be noted that, because the F-P cavity 2 already plays a role in filtering, in the camera module provided in the embodiment of the present application, no optical filter needs to be disposed, and the filtering requirement of the entire camera module is completely met by the F-P cavity 2.

With continued reference to fig. 2a, in some embodiments, at least two F-P chambers 2, comprise: the first and second

F-P cavities

21 and 22 include only one transmission peak having the same wavelength therebetween, respectively, in a case where the thickness of the first F-P cavity 21 is a first target thickness and the thickness of the second F-P cavity 22 is a second target thickness.

Referring to fig. 2b, the F-P chamber 2 includes: a substrate 201, a first reflective layer 202, a second reflective layer 204, and a conductive layer 205;

the first reflective layer 202 and the second reflective layer 204 are located between the substrate 201 and the conductive layer 205;

an adjusting component (not shown in the figure) is positioned between the first reflecting layer 202 and the second reflecting layer 204, the adjusting component is fixedly connected with the first reflecting layer 202 and the second reflecting layer 204 respectively, and the adjusting component is used for adjusting the distance between the first reflecting layer 202 and the second reflecting layer 204;

the adjusting component is electrically connected with the conductive layer 205, and the adjusting component is electrified through the conductive layer 205, so that the adjusting component is electrically controlled.

In this embodiment, the substrate 201 may be formed by a flat glass plate, the first reflective layer 202 and the second reflective layer 204 play a role of reflecting light, a cavity 203 is formed between the first reflective layer 202 and the second reflective layer 204, the adjusting member is disposed in the cavity 203, and the thickness of the whole F-P cavity 21 is adjusted by adjusting the thickness of the cavity 203.

Specifically, in some embodiments, the adjusting component is an electrostrictive polymer or an electro-optic effect polymer, and the electrostrictive polymer or the electro-optic effect polymer can deform when being electrically stimulated, so that the thickness, the refractive index and the like between the first reflecting layer 202 and the second reflecting layer 204 can be changed

It should be noted that the control of the deformation amount of the electrostrictive polymer or the electro-optic effect polymer mainly depends on the voltage value applied thereto, specifically, the corresponding relationship between the deformation amount and the voltage value may be obtained in advance through experiments or tests, and when the thickness of the F-P cavity is actually controlled, the voltage value to be used can be determined directly according to the deformation amount that needs to be adjusted.

The working principle of the F-P cavity is described as follows:

the F-P cavity is formed according to the principle of parallel panel-to-beam interference, which is shown in fig. 3, and the reflected

beams

2, 3, 4 and the transmitted beams 1 ', 2 ', 3 ' have relatively close intensities and can pass through, thereby generating the multi-beam interference phenomenon.

The spectral characteristics of the F-P cavity are shown in fig. 4 below, with several transmission peaks. Under the action of an external voltage, the thickness and the refractive index of the cavity of the electrostrictive polymer in the F-P cavity are changed, so that the wavelength of a transmission peak of the F-P cavity is shifted. Thereby achieving the purpose of tuning the wavelength.

Specifically, as shown in fig. 5, under the action of an external voltage, the cavity length and the refractive index of the medium in the cavity of two F-P cavities of each pixel point change, so that the wavelength of the transmission peak of each FP cavity moves, and the cavity lengths and the refractive indexes of the first FP cavity and the second FP cavity can be respectively controlled by controlling the voltage, so that the wavelengths of the transmission peaks of the two resonant cavities move

For example: under the action of an external voltage, the wavelengths of the transmission peaks of the two F-P cavities move (respectively, the upper diagram and the middle diagram in fig. 5), the wavelengths of the two F-P cavities are only the same in the 540nm band, the two F-P cavities are superposed, and finally only the light energy in the 540nm band penetrates (as shown in the lower diagram in fig. 5), and the rest bands cannot pass through.

The lengths of the two cavities are changed by adjusting the voltage, so that the light wave band which can be penetrated after the combined action of the first-level F-P cavity and the second-level F-P cavity is adjusted, light rays emitted by a shot object are filtered by the F-P cavity to form single wave band light, the single wave band light rays emitted by the shot object pass through, and light rays in other wave bands are filtered.

Referring to fig. 6, an execution subject of the method is an electronic device, the electronic device includes a camera module shown in fig. 2a, and the method includes the following specific steps:

step 601: determining corresponding target light wavelength according to the target photographing mode;

in the embodiment of the present application, the target photographing mode is used to indicate a photographing requirement of a user, and the target photographing mode has a corresponding relationship with a target optical wavelength, for example, the mode of photographing green vegetation and trees as pink is referred to as a "fantasy mode", and the target optical wavelength corresponding to the "fantasy mode" is an optical wavelength corresponding to the transmission range shown in fig. 1 b. Similarly, the other photographing modes correspond to different target light wavelengths respectively.

It can be understood that the target photographing mode and the corresponding target optical wavelength may be pre-stored in the electronic device as a photographing setting parameter, or may also be autonomously set by a user, that is, a user-defined photographing mode, which is not specifically limited in this embodiment of the application.

Step 602: adjusting the distance between the first reflecting layer and the second reflecting layer of each resonant cavity through an adjusting component according to the target optical wavelength, so that the thickness of each resonant cavity is adjusted to the target thickness of each resonant cavity;

in the embodiment of the application, the distance between the first reflecting layer and the second reflecting layer of each resonant cavity is adjusted through the adjusting component, so that the overall thickness of each resonant cavity is adjusted, and the thickness of each resonant cavity is adjusted to the target thickness of each resonant cavity.

Specifically, the resonant cavity is an F-P cavity, and according to the light splitting principle of the F-P cavity shown in fig. 5, the target thickness of each F-P cavity corresponding to different target light wavelengths can be predetermined, so that after the target light wavelength of each pixel point is obtained, the target thickness of each F-P cavity corresponding to each pixel point can be determined, and further, the thickness of each F-P cavity in each pixel point can be adjusted.

In some embodiments, each pixel includes a first F-P cavity and a second F-P cavity; and adjusting the thickness of the first F-P cavity to be a first target thickness and adjusting the thickness of the second F-P cavity to be a second target thickness according to the target optical wavelength.

Specifically, the thickness of each F-P cavity is adjusted to a target thickness of each F-P cavity by an adjustment component in each F-P cavity, depending on the target optical wavelength.

In some embodiments, the adjusting component is an electrostrictive polymer or an electro-optic effect polymer, and accordingly, the specific process of adjusting the thickness of each F-P cavity includes:

(1) determining the target thickness of each F-P cavity according to the preset target light wavelength;

in the embodiment of the application, the transmission peak with the same wavelength between each F-P cavity can be determined according to the wavelength of the target light, and accordingly, the target thickness of each F-P cavity can be determined according to the transmission peak. It can be understood that the wavelength of the unique transmission peak corresponding to each F-P cavity under the condition of different target thicknesses can be determined through preliminary experiments or tests, so that the thickness of each F-P cavity can be directly determined according to the target light wavelength required to be received.

(2) Determining an adjustment voltage corresponding to each F-P cavity according to the target thickness;

the corresponding relation between the adjustment voltage and the target thickness can be determined through experiments or tests in advance, and the corresponding adjustment voltage can be directly determined according to the required target thickness.

(3) A corresponding tuning voltage is applied to the tuning elements in each F-P cavity.

And adjusting the thickness of each F-P cavity to the target thickness of each F-P cavity by applying an adjusting voltage corresponding to the adjusting component in each F-P cavity.

Referring to fig. 6b to 6e, as shown in fig. 6b, according to the first target photographing mode, the thickness of the first F-P cavity 61 is adjusted to a, the thickness of the second F-P cavity 62 is adjusted to a, and then photographing is performed through the lens 60, where the distribution of the transmission peak of the F-P cavity is shown in fig. 6 c; according to the second target photographing mode, as shown in fig. 6D, the thickness of the first F-P cavity 61 is adjusted to D, the thickness of the second F-P cavity 62 is adjusted to D, and then photographing is performed through the lens 60, where the distribution of the transmission peaks of the F-P cavities is shown in fig. 6 e.

Step 603: acquiring an image through a lens in the camera module;

in the embodiment of the application, after the thickness of the F-P is adjusted, photographing is performed, and at this time, only light with the target wavelength can be acquired by the lens, so that a photographed picture conforms to a target photographing mode.
