In the camera module 100 provided by the embodiment of the present application, the optical integrated component 40 is simpler than the conventional mechanical iris diaphragm, the volume is smaller, the requirement of being lighter and thinner is more satisfied, and because the iris diaphragm 41 and the optical filter 42 jointly form the optical integrated component 40, and the optical integrated component 40 is located at the position where the lens group 30 deviates from the photosensitive chip 20, that is, the optical filter 42 is no longer located between the photosensitive chip 20 and the lens group 30, thereby the conventional camera module 100 can be omitted, a structure for fixing the optical filter 42 between the photosensitive chip 20 and the lens group 30, and further the structural size of the camera module 100 is reduced.

Moreover, the optical integrated assembly 40 formed by the iris diaphragm 41 and the optical filter 42 is arranged at a position where the lens group 30 deviates from the photosensitive chip 20, so that the optical filter 42 is far away from the photosensitive chip 20, thereby avoiding adverse effects caused by too close distance between the optical filter 42 and the photosensitive chip 20 and ensuring that no phenomena such as light spots and ghost images occur in the shooting process.

The optical integrated module 40 according to the embodiment of the present application is composed of an iris diaphragm 41 and an optical filter 42, and the iris diaphragm 41 is attached to the surface of the optical filter 42. The iris diaphragm 41 is bonded to the surface of the optical filter 42, and the iris diaphragm 41 and the optical filter 42 may be integrated into a single structure or may be connected by a connecting body in order to ensure that the iris diaphragm 41 does not easily fall off from the surface of the optical filter 42 and that the structure of the optical integrated module 40 formed by the iris diaphragm 41 and the optical filter 42 is relatively stable.

In one embodiment, the iris diaphragm 41 and the filter 42 are connected by a transparent glue. When the iris diaphragm 41 and the filter 42 are bonded by using transparent glue, the iris diaphragm 41 can be stably fixed on the surface of the filter 42, and the camera module 100 is not abnormally operated due to the falling-off of the iris diaphragm 41, and the camera module 100 is not poor in performance due to the displacement of the iris diaphragm 41. It can be understood that when the transparent glue is used for bonding, the transparent glue has good light transmittance, and does not affect the light entering amount through the lens group 30, so that the adjustment of the iris diaphragm 41 is more precise and stable.

The position relationship between the iris diaphragm 41 and the filter 42 can be two, that is, the iris diaphragm 41 is located on the surface of the filter 42 away from the lens group 30, and the iris diaphragm 41 is located on the surface of the filter 42 close to the lens group 30.

In the integrated optical module 40 provided in the embodiment of the present application, the iris diaphragm 41 is composed of a plurality of annular diaphragm pieces 410 with different inner diameters, the plurality of annular diaphragm pieces 410 are sequentially stacked on the surface of the optical filter in the order of the inner diameter with the center of the circle as the center point to form the iris diaphragm 41, the light transmission state of the annular diaphragm pieces 410 changes when the optical filter is energized, the annular diaphragm pieces 410 are in the opaque state when the optical filter is not energized and are in the transparent state when the optical filter is energized, or the annular diaphragm pieces 410 are in the opaque state when the optical filter is not energized and are in the transparent state when the optical filter is energized. In combination with the positional relationship between the variable aperture 41 and the optical filter 42 and the arrangement order of the inner diameters of the annular aperture pieces 410, there are the following four configurations of the optical integrated assembly 40.

In one embodiment, as shown in fig. 5, the variable aperture 41 is disposed at a position where the optical filter 42 is close to the lens group 30, and the inner diameters of the plurality of annular aperture plates 410 are gradually reduced in a direction along the optical filter 42 away from the lens group 30.

In one embodiment, as shown in fig. 6, the variable aperture 41 is disposed at a position where the optical filter 42 is close to the lens group 30, and the inner diameters of the plurality of annular aperture plates 410 are gradually increased in a direction along the optical filter 42 away from the lens group 30.

It should be noted that the four optical integrated components 40 can meet the corresponding functional requirements, that is, the structural size of the camera module 100 is reduced without affecting the working performance of the camera module 100.

Depending on the material of the annular diaphragm 410, the annular diaphragm 410 may be different in light transmission state when it is energized and when it is not energized.

In one embodiment, the annular aperture plate 410 is made of a dielectric material, and the annular aperture plate 410 is transparent when not energized and opaque when energized. When the iris diaphragm 41 needs to be adjusted to a certain aperture value, the functional requirements can be met only by electrifying the annular diaphragm plates 410 with corresponding inner diameters, and a plurality of annular diaphragm plates 410 do not need to be electrified at the same time, so that electric energy is saved, and the cost is reduced.

In one embodiment, the annular aperture plate 410 is made of another dielectric material, and the annular aperture plate 410 is in an opaque state when not energized and in a transparent state when energized. When the iris diaphragm 41 needs to be adjusted to a certain aperture value, all the annular diaphragm pieces 410 with the inner diameters smaller than or equal to the corresponding inner diameters need to be electrified simultaneously, so that the functional requirements can be met. However, since the annular diaphragm 410 is in the opaque state when it is not in the operating state, i.e., when the annular diaphragm 410 is not energized, the amount of light entering the lens group 30 through the variable aperture 41 is small, and damage to the lens group 30 is small, i.e., damage caused by the lens group 30 being exposed to intense light for a long period of time is avoided.

In the camera module 100 provided in the embodiment of the present application, the ratio of the inner diameters of the adjacent annular aperture plates 410 is a fixed value. When the ratio of the inner diameters of two adjacent annular diaphragm pieces 410 is the same, the annular diaphragm pieces 410 are energized, and the ratio of the incident light amount of the variable diaphragm 41 corresponding to the adjacent annular diaphragm pieces 410 is also the same. In a specific embodiment, as shown in fig. 7, the inner diameter ratio of adjacent ring-shaped aperture plates 410 is 1.4, in this case, the variable aperture 41 is adjusted by energizing to form different apertures, the aperture values of the different apertures are Fno2, Fno2.8, Fno4, Fno5.6, Fno8, Fno11, Fno16 and Fno22, that is, the adjacent ring-shaped aperture plates 410 are energized respectively, and the light incident amount of the corresponding variable aperture plates 41 is different by one time. The iris diaphragm 41 can be divided into eight gears according to the different aperture values, and the iris diaphragm 41 is adjusted to reach different aperture values, so that the depth of field effect of different scenes is obtained, and the mobile phone photographing experience of a user is improved.

It is understood that the iris diaphragm 41 is provided on the basis of the own aperture of the lens group 30, and when all the annular diaphragm 410 of the iris diaphragm 41 is in the transparent state, the amount of light entering the lens group 30 is determined by the own aperture size of the lens group 30. The aperture values of the different gears are designed based on the fact that the mainstream aperture of the current mobile phone is Fno2, that is, the aperture value of the aperture of the lens group 30 itself is Fno2, and at this time, the aperture value is the largest, and when the variable aperture 41 is used for adjustment, the aperture values can be respectively adjusted to Fno2.8, Fno4, Fno5.6, Fno8, Fno11, Fno16 and Fno22, and are sequentially reduced to satisfy the depth of field effect of different shooting scenes, and the larger the aperture value is, the smaller the depth of field is, the smaller the aperture value is, and the larger the depth of field is.

The camera module 100 provided by the embodiment of the application further includes an adjusting assembly (not shown), wherein the adjusting assembly includes a driving circuit, a driving electrode and a conductive wire, the driving circuit is disposed on the circuit board 10, the driving electrode is disposed on the iris diaphragm 41, one end of the conductive wire is electrically connected to the driving circuit, the other end of the conductive wire is electrically connected to the driving electrode, and the driving circuit is powered on to the iris diaphragm 41 through the driving electrode, so as to adjust the light transmission state of the iris diaphragm 41, and further meet the functional requirements.

As shown in fig. 1, the camera module 100 according to the embodiment of the present disclosure further includes a support 50 and a supporting member 60, the support 50 is disposed on the circuit board 10 and spaced from the photo sensor chip 20, the lens group 30 is disposed at a position of the support 50 departing from the circuit board 10, and the lens group 30 is assembled in the supporting member 60. Under the above structure, the camera module 100 can satisfy the corresponding functional requirements. The carrier 60 may be a lens barrel or a voice coil motor.

It can be understood that the electronic device provided in the embodiment of the present application is not limited to a video camera, but may also be any electronic device with a camera shooting function, such as a mobile phone, a camera, a computer, a tablet computer, and the like, which is not described in detail herein.

In the electronic device, since the iris diaphragm 41 and the optical filter 42 in the camera module 100 are integrated into a whole, the structures of the optical filter 42 and the fixed optical filter 42 between the photosensitive chip 20 and the lens group 30 can be omitted, so that the structural size of the camera module 100 is reduced, and the electronic device tends to be light and thin. Meanwhile, the optical integrated assembly 40 formed by the iris diaphragm 41 and the optical filter 42 is arranged at a position where the lens group 30 deviates from the photosensitive chip 20, so that the optical filter 42 is far away from the photosensitive chip 20, adverse effects caused by too close distance between the optical filter 42 and the photosensitive chip 20 are avoided, and phenomena such as light spots and ghost images of the electronic equipment cannot occur in the shooting process.
