Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the 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 technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Referring to fig. 1 to 4, an embodiment of the invention discloses a camera module 100, and the disclosed camera module 100 can be applied to an electronic device. The disclosed camera module 100 includes a base 110, a first photosensitive unit, a lens 130, a diaphragm adjusting part 140, a second photosensitive unit 160, and a temperature adjusting unit 170.
The base 110 is a base component of the camera module 100, and the base 110 can provide a mounting base for other components of the camera module 100. The first photosensitive unit is disposed on the base 110, the lens 130 is connected to the base 110, and the lens 130 covers the first photosensitive unit. The first light sensing unit can sense light passing through the lens 130, and finally, light sensing shooting of the camera module 100 is achieved. Specifically, the first photosensitive unit may be a photosensitive chip.
The aperture adjustment portion 140 is disposed between the first photosensitive unit and the lens 130, and specifically, the aperture adjustment portion 140 is disposed in a space covered by the lens 130, and the aperture adjustment portion 140 can adjust the size of the aperture, so that the photosensitive amount of the first photosensitive unit can be adjusted. In a specific operation process, the light passing through the lens 130 passes through the aperture adjustment portion 140, and the light sensing amount of the first light sensing unit is controlled by the adjustment of the aperture adjustment portion 140.
In the embodiment of the present invention, the aperture adjusting part 140 has a light-transmitting area including a central light-transmitting area and a light-shielding adjusting area surrounding the central light-transmitting area. Specifically, the central light-transmitting area may be a circular area, the light-shielding adjustment area may be a circular area, and the center of the circular area may coincide with the center of the circular area. Of course, the central light-transmitting area and the light-shielding adjustment area may have other shapes, and the specific shapes of the central light-transmitting area and the light-shielding adjustment area are not limited in the embodiments of the present invention. In the working process of the camera module 100, the central light-transmitting area always allows light to transmit, and the size of the central light-transmitting area can be determined according to the requirements of users. In a more preferred embodiment, the larger the ratio between the area of the light shielding adjustment region and the area of the central light transmission region, the stronger the adjustment capability of the aperture adjustment portion 140.
The shading adjusting area can shade the light, and then can adjust the light quantity projected on the first photosensitive unit. In the embodiment of the invention, the adjusting piece is arranged in the shading adjusting area, and the adjusting piece can adjust the shading area of the shading adjusting area. The second photosensitive unit 160 is electrically connected to the temperature adjustment unit 170, the second photosensitive unit 160 is used for sensing the brightness of the environment where the camera module 100 is located, and the temperature adjustment unit 170 adjusts the temperature according to the photosensitive quantity of the second photosensitive unit 160. Specifically, the temperature adjusting unit 170 can control the temperature of the adjusting member, thereby indirectly controlling the adjusting member to adjust the coverage area of the shading adjusting area, and further indirectly adjusting the light sensing amount of the first light sensing unit.
In the embodiment of the present invention, the temperature adjusting unit 170 is configured to adjust a first temperature of an adjusting member according to a light sensing amount of the second light sensing unit 160, and a first area of the adjusting member, which shields the light shielding adjustment area, is directly proportional to the first temperature. In a specific working process, the adjusting piece can expand with heat and contract with cold, and then the shading area of the shading adjusting area can be adjusted. Specifically, the temperature adjusting unit 170 may be connected to the regulating member to adjust the temperature of the regulating member.
Specifically, the temperature adjusting unit 170 can adjust the shielding area of the adjusting part in the shading adjusting area by adjusting the heating amplitude, in this case, the heating temperature of the adjusting part by the temperature adjusting unit 170 is higher, the deformation of the adjusting part is larger, the heating temperature of the adjusting part by the temperature adjusting unit 170 is lower, and the deformation of the adjusting part is smaller. The deformation amount of the regulating piece is changed by regulating the temperature of the regulating piece.
In a specific embodiment, when the light sensing amount of the second light sensing unit 160 satisfies the first preset condition, the heating value of the temperature adjusting unit 170 is increased, and the coverage area of the adjusting member on the light shielding adjusting area is increased, so that the shielding area of the light shielding adjusting area on light is increased, and the light sensing amount of the first light sensing unit can be reduced.
Under the condition that the light sensing amount of the second light sensing unit 160 meets the second preset condition, the heat productivity of the temperature adjusting unit 170 is reduced, and the coverage area of the adjusting piece to the shading adjusting area is reduced, so that the shading area of the shading adjusting area to the light is reduced, and the light sensing amount of the first light sensing unit can be increased.
It should be noted that the first preset condition and the second preset condition may represent a light intensity condition of a shooting environment where the camera module 100 is located, or may be shooting parameters preset by a user. For example, the first preset condition may be that the light sensing amount of the second light sensing unit 160 is smaller than the first preset light sensing amount, the second preset condition may be that the second light sensing unit 160 is larger than the second preset light sensing amount, and the first preset light sensing amount may be smaller than the second preset light sensing amount. In the case where the light sensing amount of the second light sensing unit 160 is smaller than the first preset light sensing amount, it can be said that the ambient brightness is low and the light quantity passing through the light blocking adjustment area needs to be increased. In the case where the photosensitive amount of the second photosensitive unit 160 is greater than the second preset photosensitive amount, it may be indicated that the ambient brightness is high and the amount of light passing through the light blocking adjustment region needs to be reduced.
Of course, the temperature adjusting unit 170 may realize the deformation of the adjusting member by cooling the adjusting member, so as to adjust the shielding area of the light shielding adjusting region.
The camera module 100 disclosed in the embodiment of the present invention improves the structure of the camera module in the prior art, so that the camera module 100 is provided with the aperture adjusting portion 140, the temperature adjusting unit 170 is configured to adjust the first temperature of the adjusting member, so that the first area of the adjusting member, which shields the light shielding adjusting area, is in direct proportion to the first temperature, and the adjusting member provided by the aperture adjusting portion 140 can adjust the shielding of the light shielding adjusting area on light, and finally can adjust the light sensing amount projected onto the first light sensing unit through the aperture adjusting portion 140. Under the condition that the light sensing amount of the first light sensing unit needs to be reduced, the temperature adjusting unit 170 enables the temperature of the adjusting piece to be increased, so that the coverage area of the adjusting piece on the shading adjusting area is increased, the shading adjusting area blocks more light, and the purpose of reducing the light sensing amount of the first light sensing unit is achieved; under the condition that the light sensing amount of the first light sensing unit needs to be increased, the temperature adjusting unit 170 can enable the temperature of the adjusting piece to be reduced, so that the coverage area of the adjusting piece on the shading adjusting area is reduced, the blocking of the shading adjusting area on light is reduced, and the light amount projected onto the first light sensing unit is increased. Compared with the conventional method of adjusting the white balance of an image through a software algorithm, the camera module 100 disclosed in the embodiment of the invention can directly adjust the throughput of ambient light through the aperture adjusting part 140 according to the intensity of the ambient light, and finally can obviously improve the image quality.
As described above, the adjusting member is provided in the light shielding adjustment region, and the adjusting member can change the coverage area of the light shielding adjustment region by the temperature adjustment unit 170. The kind of the adjusting member may be various. In the optional scheme, the adjusting part can be a solid adjusting part, and the solid adjusting part can realize expansion with heat and contraction with cold under the adjustment of the temperature adjusting unit 170, so that the volume of the adjusting part is changed, and the coverage area of the shading adjusting area is enlarged. Specifically, set up first holding tank in the shading regulation district, in the first holding tank was located to the solid regulating part, the volume of solid regulating part was less than the volume of first holding tank to can be under the condition of thermal energy, warp along the direction of lining up of first holding tank gradually.
In another alternative, a first accommodating cavity may be provided in the shading adjustment area, the solid adjustment member is provided in the first accommodating cavity, and the volume of the solid adjustment member is smaller than that of the first accommodating cavity, so that the solid adjustment member can be gradually deformed in the first accommodating cavity under the condition of thermal expansion.
First holding tank or first chamber of holding are favorable to forming the space that the volume is confirmed to be favorable to the solid regulating part to carry out comparatively normal expend with heat and contract with cold and warp. Meanwhile, the adjusting piece is a solid adjusting piece, the deformation of the solid adjusting piece is stable, and the coverage area of the shading adjusting area can be accurately adjusted. The solid state adjusting member may be of various types, for example, the solid state adjusting member may be a shape memory alloy member. The shape memory alloy part has better deformation capability under the condition of change, thereby being easier to realize the adjustment of the coverage area of the shading adjusting area.
In a more preferred embodiment, the solid conditioning member may be at least partially in contact with the temperature conditioning unit 170, so that more effective temperature conditioning is performed by contact heat conduction.
In another embodiment, the regulating member may include a first airbag and a first gas filled in the first airbag. A second accommodating groove is formed in the shading adjusting area, and the first air bag is arranged in the second accommodating groove. Of course, a second accommodating cavity can be arranged in the shading adjusting area, and the first air bag is arranged in the second accommodating cavity. The first holding tank or the second holding chamber can hold the first airbag, so that the first airbag is favorably deformed more regularly in the first holding tank or the first holding chamber under the condition that the first gas is heated. Because the expansion with heat and contraction with cold of gas is comparatively obvious under the condition of temperature variation, consequently, the regulating part of this kind of structure can make the regulation to the area covered of shading regulatory region more high-efficient.
In order to improve the deformability of the first gas, in a preferred embodiment, the regulating member may further include a gas storage box, the gas storage box is communicated with the first gas bag, the first gas is stored in the gas storage box, and the gas storage box can contain more first gas, so that more first gas can be changed in the first gas bag. Of course, alternatively, the gas storage case has a larger gas containing space, and the first gas bag can be contained in the gas storage case with the volume of the first gas bag reduced, which undoubtedly facilitates the deformation of the first gas bag. In addition, the gas storage box can also be provided with a gas pressure adjusting device, under the condition that the volume of the first gas bag needs to be reduced, the gas pressure of the gas storage box is adjusted, so that the storage capacity of the gas storage box is further improved, when the volume of the first gas bag needs to be increased, the gas pressure of the gas storage box can be reduced, so that the gas stored in the gas storage box can be rapidly filled into the first gas bag, meanwhile, the gas quantity remained in the gas storage box can be further reduced, the deformation effect of the first gas bag is improved, and the shading area can be better adjusted.
In the case where the temperature adjusting unit 170 heats the first gas, the first gas is thermally expanded, and the area of the first air bladder covering the light blocking adjustment area is increased, so that the light sensing amount of the first light sensing unit is decreased. In the case where the temperature adjusting unit 170 cools the first gas, the first gas is cooled and contracted, and the area of the first gas bag that shields the light blocking adjustment area is reduced.
In an embodiment of the present invention, the gas storage box is disposed on the base 110, and the camera module further includes a gas guiding tube, and the first airbag is communicated with the gas storage box through the gas guiding tube. Because the air duct can play the effect that links up, consequently can make gas storage box have more the setting position on base 110 to the realization is assembled comparatively flexibly.
The first gas may be a variety of types, and in a preferred embodiment, the first gas may be nitrogen or an inert gas, which is relatively stable and not easily adversely affected.
In yet another specific embodiment, the regulating member may include a first light-shielding liquid, and the light-shielding regulating region is a light-shielding liquid-filled region. Under the condition that the temperature adjusting unit 170 heats the first light-shielding liquid, the first light-shielding liquid expands, the area of the light-shielding adjusting area shielded by the first light-shielding liquid increases, and therefore light blocking with a larger area is achieved. In the case where the temperature adjusting unit 170 cools the first light-shielding liquid, the area of the light-shielding adjustment region shielded by the first light-shielding liquid decreases. In this concrete scheme, the regulating part includes first shading liquid, and first shading liquid has good mobility and fillability to can pack in shading liquid filling area better, reach better filling effect. Meanwhile, compared with the first gas, the first light-shielding liquid is less affected by the ambient temperature, so that a relatively stable filling function can be exerted.
In the case where the adjuster includes the first light-shielding liquid, in the case where the temperature adjusting unit 170 heats the first light-shielding liquid, the first light-shielding liquid can be expanded in a liquid state, and the first light-shielding liquid may be kept in a liquid state all the time. Of course, it may also be: under the condition that the temperature adjusting unit 170 heats the first shading liquid, the first shading liquid can be changed from a liquid state to a gaseous state, so that the shading area of the shading adjusting area can be adjusted more quickly, and the purpose of efficient adjustment is achieved.
In a preferred scheme, the shading liquid filling area can be internally stored with second gas, and the second gas can maintain the air pressure balance in the shading liquid filling area, so that the influence of the air pressure in the external environment on the first shading liquid can be avoided.
Similarly, in a preferable embodiment, the adjusting member disclosed in the embodiment of the present invention may further include a light-shielding liquid storage box 150, and the light-shielding liquid storage box 150 is communicated with the light-shielding liquid filling region. Specifically, the first light-shielding liquid may be a non-light-transmissive liquid, such as ink, metallic mercury, an opaque organic liquid, and the like.
