While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
An embodiment of the present invention provides a camera module, and referring to fig. 1 to 6, the camera module may include: a carrier 10, a plurality of lenses 11 fixedly disposed on the carrier 10, an image sensor 12 movable below the lenses 11, and a driving mechanism 13; the driving mechanism 13 is used for driving the image sensor 12 to move so as to align the image sensor 12 with one of the lenses 11.
The camera module provided by the embodiment of the invention realizes the multiplexing of the image sensor by matching the image sensor with the plurality of lenses, and meets the requirement of a user on the diversification of the camera shooting function; meanwhile, the embodiment of the invention reduces the whole volume and the cost of the camera module, and the plurality of lenses which are fixedly arranged avoid the relative movement between the lenses and the external equipment, thereby avoiding the gap between the lenses and the external equipment and meeting the sealing requirements of dust prevention, water prevention and the like.
Further, when image sensor's imaging quality is higher, just can make the image that every camera lens of matching was gathered all have higher formation of image effect to make the whole formation of image effect of the module of making a video recording obtain promoting, and then can promote user's use and experience. Furthermore, one image sensor is used for matching, so that the development period of engineers is shortened, and the optimization in the whole software debugging is more convenient.
It should be noted that the lens in the embodiment of the present invention includes, but is not limited to, the following lenses: a macro lens, a telephoto lens, a wide-angle lens, a zoom lens, and a fixed focus lens. It should be noted that, the camera module in this embodiment may further include a hollow housing, the bearing, the lens, the image sensor, and the driving mechanism are disposed in a hollow structure surrounded by the housing, and the bearing and the driving mechanism are disposed on an inner surface of the housing respectively.
The embodiment of the invention provides two lens arrangement modes, one is linear arrangement mode, and the other is circumferential distribution mode, wherein the two lens arrangement modes adopt different driving modes when driving the image sensor to move and align, and the specific description is as follows.
It should be noted that, in the embodiment of the present invention, the driving mechanism may be a voice coil motor, a piezoelectric ceramic motor, a stepper motor, or the like, and the specific type or type of the driving mechanism is not limited in the embodiment of the present invention.
In an optional embodiment, the lens arrangement in this embodiment is a linear arrangement, and referring to fig. 2, the camera module may further include: a rail 14 provided on the carrier 10; the image sensor 12 is mounted on the rail 14;
the arrangement of the plurality of lenses 11 on the carrier 10 matches the shape of the rail 14;
the driving mechanism 13 is used for driving the image sensor 12 to move on the rail 14.
The rail provided in the embodiment of the present invention may be a slide rail, and the rail may support the image sensor, and the image sensor may slide on the rail. Furthermore, the inventor finds that if one image sensor matches multiple lenses, when the multiple lenses move and the image sensor is fixedly arranged, empty spaces of the multiple lenses need to be reserved to match all the lenses (for example, if there are n lenses, there need to be 2n-1 lens positions to match all the lenses).
In another alternative embodiment, the lens arrangement in this embodiment is a linear arrangement, and referring to fig. 3, the camera module may further include: a rack 15 and a gear 16 connected to the drive mechanism 13; the rack 15 is meshed with the gear 16;
the image sensor 12 is arranged at one end of the rack 15 far away from the gear 16; the arrangement mode of the plurality of lenses 11 on the carrier 10 is matched with the extending shape of the rack 15;
the driving mechanism 13 is used for driving the gear 16 to rotate so as to drive the image sensor 12 on the rack 15 to move.
In this embodiment, the driving gear drives the rack to stretch when rotating, so as to drive the image sensor to move under one of the lenses and align. It should be noted that the rack in this embodiment may be a long strip or a curved rack, and the specific shape of the rack is not limited in this embodiment of the present invention, but the arrangement manner of the plurality of lenses on the carrier must match the shape of the rack, that is, match the movement track of the rack. It should be noted that, in the present embodiment, the rack is configured such that only one side of the rack engaged with the gear is provided with teeth, and the other side is used for fixedly mounting the image sensor.
In another alternative embodiment, the lens arrangement manner in this embodiment is a circumferential distribution arrangement manner, and as shown in fig. 4, the camera module may further include: a turntable 17;
the image sensor 12 is arranged on the turntable 17; the driving mechanism 13 is used for driving the turntable 17 to rotate, so that the turntable 17 drives the image sensor 12 to rotate; the carrier 10 has a disk shape, and a plurality of lenses 11 are arranged on the carrier 10 at a predetermined angle.
It should be noted that, in the embodiment of the present invention, the centers of the turntable and the carrier are located on the same straight line in the vertical direction. Further, in this embodiment, the distance from the axis of each lens to the center of the bearing member is also the same, and the distance is the same as the distance from the image sensor to the center of the turntable, so that it can be ensured that the image sensor on the turntable can be matched with any lens when the turntable rotates.
When the image sensor in the embodiment of the present invention is disposed on the turntable, at least 3 driving methods may be adopted to drive the turntable to rotate, which are as follows:
< embodiment 1>
Referring to fig. 4, the output end of the driving mechanism 13 is directly connected to the center of the turntable 17, that is, the output end of the driving mechanism is vertically connected to the center of the turntable, and when the driving mechanism drives the turntable to rotate, the driving mechanism drives the image sensor on the turntable to move.
The inventor finds that when the driving mechanisms are connected to the center of the turntable, the thickness of the whole camera module is larger, and such an assembly relationship is not favorable for being applied to ultrathin intelligent electronic equipment, such as a smart phone, a smart tablet computer and the like, and the space occupation of the camera module used by the intelligent electronic equipment is as small as possible. In order to save the space occupation ratio of the camera module, the inventor innovatively adopts the driving connection modes of the modes 2 and 3.
< mode 2>
Referring to fig. 5, the camera module may include: a rotating shaft 18, a gear 16 and a rack 15 respectively engaged with the rotating shaft 18 and the gear 16; the rotating shaft 18 is arranged at the center of the rotating disc 17, and the gear 16 is connected with the driving mechanism 13; the driving mechanism 13 is used for driving the gear 16 to rotate so as to drive the rotating shaft 18 meshed with the rack 15 to rotate, so that the turntable 17 drives the image sensor 12 to rotate.
It should be noted that, in the embodiment of the present invention, the driving mechanism is disposed side by side with other portions of the camera module, so that the space in the vertical direction is compressed, and the thickness of the whole camera module is reduced. The turntable is driven to drive the image sensor to rotate to a position below the target lens and align the target lens in a mechanical connection mode of a gear, a rack, a rotating shaft and the like.
< mode 3>
Referring to fig. 6, the camera module may include: a belt 19; the driving mechanism 13 is connected with the rotary table 17 through a transmission belt 19;
the driving mechanism 13 drives the turntable 17 to rotate through the transmission belt 19, so as to rotate the image sensor 12 on the turntable 17.
It should be noted that the above-mentioned driving belt can be a belt or a chain, and when the above-mentioned driving belt is used, a clamping groove can be arranged at the circumferential edge of the turntable so as to facilitate the embedding of the driving belt, and a protrusion/convex tooth can also be arranged at the circumferential edge of the turntable so as to facilitate the clamping of the chain and the like. Of course, a transmission shaft may be disposed at the center of the turntable to connect the transmission belt, and the connection manner of the transmission belt and the turntable is not particularly limited in the embodiment of the present invention.
Based on the same inventive concept, an embodiment of the present invention further provides a method for controlling switching of lenses in the camera module, in the present invention, switching of lenses is implemented by moving a position of an image sensor, and as shown in fig. 7, the method may include the following steps:
and step S71, receiving a control command.
In this step, the control instruction received by the camera module may be a control instruction sent by a user, or a control instruction sent by an upper control device of the camera module. For example, when the camera module is installed on a smart phone, a control instruction for switching a photographing mode (and generating a switching lens) by clicking a user can be received, or the control instruction can be sent by the smart phone when an APP in the smart phone is adapted to a photographing scene.
And step S72, determining the matched target shot according to the scene parameters contained in the control command.
It should be noted that the control instruction in the embodiment of the present invention includes scene parameters, and different scene parameters may match different camera lenses, and this step is mainly a process of identifying and determining a target lens.
Wherein the scene parameters include at least one of: shooting mode, light brightness, object focusing distance and shooting time. The photographing mode may include: the method comprises a portrait shooting mode, a large-aperture shooting mode, a night scene shooting mode and the like.
And step S73, judging whether the target lens is the current lens aligned by the image sensor. If not, go to step S74; otherwise, step S75 is executed.
And step S74, controlling the driving mechanism to drive the image sensor to move to the position below the target lens and align.
And step S75, lenses do not need to be switched.
The method for controlling the lens switching in the camera module, provided by the embodiment of the invention, determines the target lens matched with the photographing by identifying the scene parameters contained in the control command, judges whether the target lens is the current lens aligned with the image sensor, and controls the driving mechanism to drive the image sensor to move to the position below the target lens and align the target lens if the target lens is not the current lens aligned with the image sensor. The lens switching control method is a control method aiming at matching a plurality of lenses with one image sensor, realizes the multiplexing of the image sensor and meets the requirement of a user on the diversification of the camera shooting function.
In an optional embodiment, the implementation of step S74 includes: calculating the movement displacement and/or the rotation angle of the image sensor according to the position of the current lens and the position of the target lens;
and controlling the driving mechanism to drive the image sensor to move by corresponding displacement and/or rotate by corresponding angle to be aligned with the target lens.
It should be noted that, in the embodiment of the present invention, it is necessary to pre-store the configuration information of the lens and the position information of the lens, and the upper control device controlling the camera module generates the driving control instruction according to the configuration information and the position information, so as to control the image sensor to move under the target lens and align when it is determined that the target lens is not the current lens aligned by the image sensor.
In a specific embodiment, referring to fig. 8, after the camera module is started, the method for controlling switching of lenses in the camera module may specifically include the following steps:
step S801, acquiring image data collected by the image sensor under the plurality of lenses respectively.
In this step, after the camera module is opened, the driving mechanism can drive the image sensor to move under each lens and align, and then image data is collected to generate a plurality of images.
And S802, comparing the definition values of the image data collected by the image sensor under the lens, and selecting the lens matched with the image sensor.
In this step, sharpness value comparison is performed on a plurality of collected image data (i.e., generated images), for example, images with the highest sharpness under all different shots are compared, and the shot is determined as a shot paired with the image sensor.
Step S803, control the driving mechanism to drive the image sensor to move under the lens and align. At this time, the image acquired under the shot is the clearest image, but the image is not necessarily a shooting scene required by the user or APP.
And step S804, controlling the driving mechanism to drive the image sensor to move to a position below the default lens and align.
And step S805, receiving a control instruction. This step can be referred to as step S71, and will not be described herein.
Step S806, determining the matched target shots according to the scene parameters included in the control command. This step can be referred to as step S72, and will not be described herein.
Step S807, determine whether the target lens is the current lens aligned by the image sensor. If not, executing step S808; otherwise, step S811 is performed. This step can be referred to as step S73, and will not be described herein.
And step S808, controlling the image sensor to stop collecting the image data. In the step, the image sensor stops collecting the image data, so that the situation that the collected image data is not a correct image or the collected image data is incomplete when the lens is switched is avoided, and poor picture experience such as unsmooth blocking is avoided for a user.
And step 809, calculating the movement displacement and/or the rotation angle of the image sensor according to the position of the current lens and the position of the target lens. In this step, the displacement or angle of the image sensor from the aligned current lens to the target lens is calculated by calculating the position information of the lens and the position information of the target lens, so as to generate a control command of movement to control the driving mechanism to move the image sensor.
It should be noted that, in this embodiment, the execution sequence of the step S808 and the step S809 is not sequential, the step S808 may be executed first, the step S809 may be executed first, or the steps may also be executed simultaneously, which is not specifically limited in this embodiment of the present invention.
And step S810, controlling the driving mechanism to drive the image sensor to move by corresponding displacement and/or rotate by corresponding angle, and aligning with the target lens.
Step S811, no lens switching is required.
