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.
As shown in fig. 1 to 4, an embodiment of the present invention discloses a camera module, which can be applied to a mobile terminal, and includes a camera holder 100, a camera 300, a light intake amount adjuster 400, and a driving mechanism 500. The camera bracket 100 is a bearing part of the whole camera module. The number of cameras 300 may be at least two, each camera 300 being mounted to the camera support 100, the field of view 330 of the camera 300 being shown in fig. 2 and 3.
The light inlet amount adjusting member 400 is provided with a plurality of light inlets 410, the light inlets 410 can transmit light, and the light transmitting areas of at least two light inlets 410 are different, so that different light inlets can be obtained in different states, and the light inlet amount of the camera module can be adjusted. The light inlet 410 may be a circular hole, and at this time, the light passing area of the light inlet 410 is related to the aperture of the light inlet 410, and the larger the aperture is, the larger the light passing area is, and the smaller the aperture is, the smaller the light passing area is. The light inlet amount adjusting member 400 is movably installed in the camera holder 100, and at least one camera 300 is opposite to the light inlet hole 410 having a different light transmission area in the movable stroke of the light inlet amount adjusting member 400. That is, when the position of the light amount adjusting member 400 with respect to the camera head holder 100 is changed, the light entrance hole 410 facing the camera head 300 is also changed, so that the amount of light entering the camera head 300 is changed. Specifically, the light inlet amount adjusting element 400 may be slidably disposed on the camera holder 100, or may be rotatably disposed on the camera holder 100, in order to simplify the structure and control procedure of the camera module, in an embodiment of the present invention, the light inlet amount adjusting element 400 is rotatably disposed on the camera holder 100, and the rotation angle may be 180 °, 360 °, or an integral multiple of 360 °.
The driving mechanism 500 is drivingly connected to the light intake amount adjusting member 400 to apply a driving force to the light intake amount adjusting member 400 so that the light intake amount adjusting member 400 moves relative to the camera head bracket 100. When the light inlet amount adjusting element 400 is rotatably disposed on the camera bracket 100, the driving mechanism 500 specifically includes a driving source and a rotating shaft 510 fixedly connected to the light inlet amount adjusting element 400, and a driving shaft of the driving source can be coaxially fixed with the rotating shaft 510, so as to drive the rotating shaft 510 to rotate, so that the light inlet amount adjusting element 400 rotates therewith.
As can be seen from the above, in the camera module disclosed in the embodiment of the present invention, at least two cameras 300 are provided, at least two light inlet holes 410 with different light transmission areas are provided in the light inlet amount adjusting piece 400, and the driving mechanism 500 can drive the light inlet amount adjusting piece 400 to move, so that at least one camera 300 can be opposite to the light inlet hole 410 with different light transmission areas, and the light inlet amount of the camera 300 can be changed. Therefore, after the camera module is adopted, the user can adjust the light inlet quantity of the camera 300 according to different scenes, and the multiple cameras 300 can be combined, so that the shooting requirements of the user under different scenes are met.
Of course, the light entering amount of the camera 300 can also be adjusted according to the light intensity of the environment where the camera module is located, so as to achieve the purpose of improving the imaging effect. Specifically, in a low-light environment, the current light-entering amount of the camera 300 is relatively small, and at this time, the driving mechanism 500 drives the light-entering amount adjusting piece 400 to work, so that the light-entering hole 410 with a larger light-passing area is opposite to the camera 300, the light-entering amount of the camera 300 is increased, and the purpose of improving the shooting effect is achieved. On the contrary, in a strong light environment, the current light entering amount of the camera 300 is larger, and at this time, the driving mechanism 500 drives the light entering amount adjusting piece 400 to work, so that the light entering hole 410 with a smaller light passing area is opposite to the camera 300, the light entering amount of the camera 300 is reduced, and the purpose of improving the shooting effect is achieved. In a backlight environment, the light entrance hole 410 facing the camera 300 can be changed by the driving mechanism 500 as well, and the amount of light entering the subject is increased, so that the taken picture is brighter. When the depth-of-field imaging is adopted, the light entering amount of the camera 300 can be flexibly adjusted to adapt to different shooting environments, and the depth-of-field imaging effect is optimized.
Alternatively, in order to reduce the space occupied by the light intake amount adjusting member 400, the light intake holes 410 may be arranged along the rotation direction of the light intake amount adjusting member 400, that is, the centers of the light intake holes 410 are located on the same circumference.
As described above, the light amount adjusting member 400 is rotatably connected to the camera head bracket 100 via the rotating shaft 510, the driving source of the driving mechanism 500 may be the driving motor 520, and if the driving motor 520 directly drives the rotating shaft 510, the driving motor 520 can only be disposed along the extending direction of the rotating shaft 510, which results in a large space size of the camera module. To solve this problem, the driving mechanism may further include a gear transmission part 530, and the driving motor 520 is in transmission connection with the rotating shaft 510 through the gear transmission part 530. The gear transmission part 530 can change the transmission direction of the acting force, and then the arrangement mode of the driving motor 520 can be flexibly selected according to the actual situation, so that the whole camera module is more compact in structure and smaller in occupied space.
The gear transmission part 530 may specifically include a first gear shaft 531 provided on the camera bracket 100 and a first bevel gear 532 sleeved on the first gear shaft 531, wherein a worm section 511 is provided on the rotating shaft 510, and the worm section 511 is engaged with the first bevel gear 532. In this case, the first helical gear 532 and the worm section 511 may form a worm-and-wheel pair, and further, the transmission of the force is realized by a simple structure, and this transmission method also has advantages of a large transmission ratio, a compact structure, smooth transmission, no noise, self-locking property, and the like.
In a specific embodiment, the first gear shaft 531 can be directly fixed coaxially with the driving shaft of the driving motor 520, and then drive the first bevel gear 532 to rotate. However, since the distance between the driving shaft of the driving motor 520 and the rotating shaft 510 is large, the size of the first bevel gear 532 is large, and the space size of the camera module is large. For this purpose, the gear transmission part 530 further includes a second gear shaft 533 disposed on the camera bracket 100 and a second bevel gear 534 sleeved on the second gear shaft 533, and the driving motor 520 is in transmission connection with the first bevel gear 532 through the second bevel gear 534. At this point, the smaller size second beveled gear 534 is used to transfer the force to the first beveled gear 532.
It should be noted that the second bevel gears 534 and the second gear shafts 533 may be arranged in groups, and may be arranged in one group, or may be arranged in two groups, specifically, the selection may be performed according to the overall structure of the camera module. In addition, a receiving groove 110 may be formed in the camera bracket 100, and the rotating shaft 510, the first gear shaft 531, the first helical gear 532, the second gear shaft 533 and the second helical gear 534 are all located in the receiving groove 110, so as to further improve the structural compactness of the camera module.
In an alternative embodiment, two cameras 300 may be provided, namely, a first camera 310 and a second camera 320, and the first camera 310 and the second camera 320 are simultaneously opposite to the two light inlets 410. That is to say, the embodiment of the present invention can adjust the light incident amount according to the structure of the dual cameras, so that the first camera 310 and the second camera 320 can both obtain a better shooting effect.
After the first camera 310 and the second camera 320 are disposed, the rotation axis of the light inlet amount adjusting member 400 may be located in a plane formed by the axes of the two light inlet holes 410. During the rotation of the light inlet amount adjusting member 400, the two light inlet holes 410 can be more reliably opposite to the first camera 310 and the second camera 320 at the same time, which is more convenient for the first camera 310 and the second camera 320 to shoot at the same time.
Further, the camera module disclosed in the embodiment of the present invention may further include a bracket cover 200, where the bracket cover 200 is installed on the camera bracket 100 and located below the bracket cover 200. The holder cover 200 is provided with a light hole 210, and the light hole 210 is opposite to the light inlet 410 and can allow light entering the light inlet 410 to pass through. The light-passing area of the light-passing hole 210 is larger than that of the light-entering hole 410, the light-passing hole 210 can also be set as a circular hole, and the aperture of the light-passing hole 210 is larger than that of the light-entering hole 410. The holder cover 200 may block external foreign substances from entering the camera 300 on the basis of allowing external light to enter the camera 300. When the cameras 300 are provided in two, the light passing holes 210 on the stand cover 200 may be provided in two, and the two light passing holes 210 are respectively disposed opposite to the first camera 310 and the second camera 320.
In a further embodiment, a mounting groove 220 may be provided on a surface of the holder cover 200 facing the light amount adjusting member 400, and the light amount adjusting member 400 is positioned in the mounting groove 220. The light inlet amount adjusting piece 400 is assembled in a slotted mode, so that the space occupied by the light inlet amount adjusting piece 400 can be reduced, and the space occupied by the whole camera module is reduced accordingly.
When the light inlet amount adjusting member 400 is rotatably disposed on the camera bracket 100, further, the sidewall of the mounting groove 220 is an arc sidewall, and the center of the circle where the arc sidewall is located is the rotation center of the light inlet amount adjusting member 400. The light amount adjusting member 400 may be configured as a disc structure, and a gap between the arc-shaped sidewall of the mounting groove 220 and the edge of the light amount adjusting member 400 may be set as small as possible, so that the arc-shaped sidewall assists in limiting the light amount adjusting member 400, and the smoothness of the light amount adjusting member 400 when rotating is not affected.
As shown in fig. 5, an embodiment of the present invention further discloses a method for controlling a camera module, which is used for controlling the camera module according to any one of the embodiments, and includes the following steps:
s100, acquiring the light entering amount of the current light entering hole 410 of the camera module.
Specifically, before the camera module does not perform a shooting operation, light of an external environment can enter the inside of the camera 300 through the current light inlet (i.e., the light inlet 410 opposite to the camera 300 in this state), and then is sensed by a chip inside the camera 300, the chip generates a corresponding electrical signal according to the intensity of light, and the electrical signal can be transmitted to a control chip (e.g., a control chip of a mobile terminal), so that the control chip obtains the light inlet amount of the current light inlet of the camera module. Of course, the light entering amount corresponding to each light entering hole 410 may be stored in advance, and the light entering amount of the current light entering hole 410 may be obtained by detecting the light entering hole corresponding to the camera 300.
And S110, judging whether the light inlet quantity is larger than a preset value, if so, entering a step S120, and otherwise, entering a step S130.
After the control chip obtains the light entering amount of the current light entering hole of the camera module, the light entering amount can be compared with a preset value, the preset value is the corresponding light entering amount when the shooting effect is ideal, and the preset value can be prestored in equipment comprising the camera module provided by the embodiment of the invention.
S120, driving the light intake amount adjusting member 400 to move through the driving mechanism 500, so that the target light intake hole on the light intake amount adjusting member 400 is opposite to the camera 300, and the light transmission area of the target light intake hole is smaller than that of the current light intake hole.
If the current light amount is larger than the preset value, the light amount is too large, and the light amount needs to be reduced to obtain a relatively ideal shooting effect. Accordingly, the control chip can control the voltage of the driving mechanism 500, so that the driving mechanism 500 drives the light inlet amount adjusting member 400 to move, and further, the target light inlet hole with a smaller light transmission area is aligned with the camera 300, thereby reducing the light inlet amount. It should be noted that the light passing area of each light inlet 410 and the position of the light inlet on the light inlet adjusting member 400 can be pre-stored in the device, and the control chip can know the required rotation angle of the light inlet adjusting member 400 according to the pre-stored information and control the driving mechanism 500 accordingly.
And S130, judging whether the light inlet quantity is smaller than a preset value, if so, entering the step S140, and if not, ending.
S140, driving the light intake amount adjusting piece 400 to move through the driving mechanism 500, so that the target light intake hole on the light intake amount adjusting piece 400 is opposite to the camera 300, and the light transmission area of the target light intake hole is larger than that of the current light intake hole.
If the current light amount is smaller than the preset value, the light amount is too small, and the light amount needs to be increased to obtain a relatively ideal shooting effect. Accordingly, the control chip can control the voltage of the driving mechanism 500, so that the driving mechanism 500 drives the light inlet amount adjusting member 400 to move, and further, the target light inlet hole with a larger light transmission area is aligned with the camera 300, thereby increasing the light inlet amount.
The embodiment of the invention also discloses a mobile terminal which comprises the camera module disclosed by any one of the embodiments. The mobile terminal disclosed by the embodiment of the invention can be a smart phone, a tablet computer, an electronic book reader or a wearable device. Of course, the mobile terminal may also be other terminal devices, which is not limited in this embodiment of the present invention.
In the above embodiments of the present invention, the difference between the embodiments is mainly described, and different optimization features between the embodiments can be combined to form a better embodiment as long as they are not contradictory, and further description is omitted here in view of brevity of the text.
