The utility model provides a camera module can be applied to electronic equipment such as cell-phone, flat board.

As shown in fig. 1, a camera module 100 according to an embodiment of the present invention includes a first imaging module 10. As shown in fig. 1, the first imaging module 10 includes a housing 110, a lens group 120 disposed within the housing 110, at least two image sensors, and a first light path changing element 140. As an example, fig. 1 illustrates a case where two image sensors, i.e., the first image sensor 131 and the second image sensor 132, are provided, but the number of image sensors is not limited to two, and more than two image sensors are included.

In the present embodiment, the first image sensor 131 and the second image sensor 132 are disposed on the same side of the lens group 120 in the optical axis Z direction of the lens group 120, and specifically, the first image sensor 131 and the second image sensor 132 are both located on the image side of the lens group 120. The image side refers to a side of the camera module 100 away from the object to be photographed; the object side corresponds to the image side, and means the side of the camera module 100 close to the object when in use.

The first optical path changing element 140 is movably disposed between the lens group 120 and the at least two image sensors. The first optical path changing element 140 may be movable, and may change a transmission direction of the light emitted from the lens group 120 to be directed to a different image sensor. In a specific arrangement, the first optical path changing element 140 may be rotated or may be translated along the optical axis Z.

Specifically, in the present embodiment, the light a emitted from the lens group 120 passes through the first optical path changing element 140 and is then emitted to the first image sensor 131 or the second image sensor 132. As shown in fig. 1, when the light emitted from the lens group 120 is directed to the first image sensor 131, the first image sensor 131 and the lens group 120 constitute a first imaging unit having a first equivalent focal length. As shown in fig. 2, when the light a emitted from the lens group 120 is emitted to the second image sensor 132 after the first optical path changing element 140 rotates by 90 degrees, the second image sensor 132 and the lens group 120 constitute a second imaging unit having a second equivalent focal length different from the first equivalent focal length. When the number of image sensors is more than two, by analogy, a plurality of imaging units with different equivalent focal lengths will be formed.

The embodiment of the utility model provides an in, equivalent focal length means the length of camera image sensor chip image area diagonal, and when the equivalent becomes 35mm camera frame diagonal length (42.27mm), the focus of the actual focus of its camera lens corresponds 35mm camera lens. When the length of the diagonal line of the image area of the first image sensor 131 is different from the length of the diagonal line of the image area of the second image sensor 132, the first image sensor 131 and the lens assembly 120 form a first imaging unit having a first equivalent focal length, and the second image sensor 132 and the lens assembly 120 form a second imaging unit having a second equivalent focal length, the first equivalent focal length and the second equivalent focal length are different. In this way, when the first image sensor 131 and the second image sensor 132 are switched, the equivalent focal length of the camera module 100 is changed.

In the above embodiment, the first optical path changing element 140 rotates to direct the light emitted from the lens group 120 to different image sensors, so as to switch different equivalent focal lengths, thereby achieving different zoom magnifications. In the zooming process, the same lens group 120 is used, and compared with the traditional technology, different lens groups are needed, so that the internal structure of the camera module is simplified. When the number of the image sensors is more than two, the camera module 100 can realize more effects with different zoom magnifications by switching the image sensors.

The first equivalent focal length of the first imaging unit is different from the second equivalent focal length of the second imaging unit, and various implementations are possible. In a specific configuration, the shapes and sizes (i.e., sizes) of the second image sensor 132 of the first image sensor 131 are different, so that the light emitted from the lens group 120 forms images on the second image sensor 132 of the first image sensor 131 with different effects, and the calculated equivalent focal lengths are different. Thus, by rotating the first optical path changing element 140, switching between different image sensors for use in pairs with the lens group 120 is achieved, thereby achieving the effect of different zoom magnifications.

In other embodiments, the second image sensor 132 of the first image sensor 131 may be configured to have different sizes, but have the same shape, and the effect of the light emitted from the lens group 120 when the light is imaged on the first image sensor 13 and the second image sensor 132 is different, and the calculated equivalent focal length is different. The first optical path changing member 140 may rotate to guide the light a emitted from the lens group 120 to the first image sensor 131 or the second image sensor 132 while the position is changed. In particular, as shown in fig. 1 and 2, the first light path changing element 140 is a prism provided with only one light reflecting surface 141. Specifically, the first light path changing element 140 includes a light reflecting surface 141, a first light incident surface 142, and a second light incident surface 143. More specifically, the prism is a right-angle prism, and the light-reflecting surface 141 is a surface corresponding to the hypotenuse.

As shown in fig. 1, the light reflecting surface 141 of the first optical path changing element 140 is at the first position, the first light incident surface 142 is close to the lens group 120, and the light a emitted from the lens group 120 enters the prism from the first light incident surface 142, is reflected by the light reflecting surface 141, and then exits through the second light incident surface 143 to be emitted to the first image sensor 131. As shown in fig. 2, after the first optical path changing element 140 rotates by 90 degrees, the light a emitted from the lens group 120 enters the prism through the second light incident surface 143, is reflected by the light reflecting surface 141, and then exits to the second image sensor 132 through the first light incident surface 142. In addition, the first light path changing member 140 may also be a flat mirror having a coated film on the back side.

In the above embodiment, the position of the light reflecting surface 141 is changed by rotating the first optical path changing element 140, so that the light emitted from the lens group 120 can be emitted to the first image sensor 131 or the second image sensor 132, thereby achieving the effect of different zoom magnifications.

In other embodiments, the first optical path changing element 140 is disposed in the housing 110 of the camera module 100 in a manner of being capable of translating along the optical axis Z direction, and the at least two image sensors are sequentially arranged along the optical axis Z direction and located on the same side of the first optical path changing element 140. As shown in fig. 5, taking the first image sensor 131 and the second image sensor 132 as an example, in a specific arrangement, the first optical path changing element 140, the first image sensor 131 and the second image sensor 132 are all located on the image side of the lens group 120, the first image sensor 131 and the second image sensor 132 are all located on the same side of the first optical path changing element 140, and the first optical path changing element 140 is a right-angle prism. Specifically, as shown in fig. 5, the first image sensor 131 and the second image sensor 132 are located on the same side of the second light incident surface 143 of the first optical path changing element 140, wherein the second light incident surface 143 of the first optical path changing element 140 is opposite to the first image sensor 131, and the first image sensor 131 is paired with the lens group 120. When the first optical path changing element 140 is moved to the right, the second light incident surface 143 moves to a position opposite to the second image sensor 132, so that the second image sensor 132 is used in combination with the lens group 120.

In the above embodiment, the first optical path changing element 140 is translated to enable the light emitted from the lens group 120 to be emitted to the first image sensor 131 or the second image sensor 132, so as to achieve the effect of different zoom magnifications.

As shown in fig. 1 and 2, the first optical path changing element 140 is rotatably provided in the housing 110 of the camera module. By rotating the first optical path changing element 140, the purpose of switching the first image sensor 131 and the second image sensor 131 is achieved. Wherein the rotation of the first light path changing element 140 may be implemented in various ways.

As shown in fig. 1 and fig. 3, in a possible embodiment, the camera module 100 further includes a control device for controlling the rotation of the first optical path changing element 140, and the control device includes a driving mechanism 151 disposed in the housing 110, and the driving mechanism 151 is used for realizing the rotation of the first optical path changing element 140.

The drive mechanism 151 may comprise a manually or electrically controlled push rod. When manually controlled, the operating button of the push rod is located outside the housing 10, and when mounted to the electronic device, the operating button is located outside the electronic device.

When the control is electric, the push rod is an electric push rod, and the driving motor of the electric push rod is controlled by the controller 152 on the main board of the electronic device. In addition, the lens assembly 120 itself may also be a zoom lens assembly, and the lens assembly 120 includes a zoom lens assembly and a voice coil motor, and the type of the voice coil motor is not limited. The controller 152 may also be used to control the zooming of the lens assembly 120. Of course, the lens groups 120 may be all fixed focus lens groups.

Further, the control device further includes a position sensor 153 disposed in the housing 110. The position sensor 153 is used to detect whether the first optical path changing element 140 is rotated to the right position, and feeds back a signal to the controller 152, forming a closed-loop feedback control system. In a specific arrangement, the position sensor 153 may be a hall sensor or a pressure sensor. Hall sensor or pressure sensor are small, are convenient for set up in the shell, and have the high advantage of sensitivity, realize realizing the accurate control to first light path change element 140 position, realize accurate switching camera module multiplying power.

Taking the first optical path changing element 140 rotating from the first position to the second position as an example, a position sensor 153 is disposed on the inner wall of the housing 10 corresponding to the second position. When the magnification selected by the user is the magnification that can be provided by the second imaging unit, the controller 152 drives the first optical path changing element 140 to rotate through the driving mechanism 151, and whether the first optical path changing element 140 rotates in place is judged according to the signal feedback of the position sensor 153, thus forming a closed-loop feedback control system. The second position is the optimum position of the first optical path changing element 140 required for the magnification, and if the first optical path changing element 140 is not in position, the controller 153 finely adjusts the first optical path changing element 140 by the driving mechanism 151. Similarly, another position sensor 153 is also disposed on the inner wall of the housing 10 corresponding to the first position, and the position detection and adjustment method is the same as the above process, and will not be described again.

In the camera module 100 according to the above embodiment, the number of the image sensors is two, that is, the first image sensor 131 and the second image sensor 132 are included. Specifically, the first image sensor 131 and the second image sensor 132 are arranged in parallel and on both sides of the optical axis Z, and the first optical path changing element 140 is located between the first image sensor 131 and the second image sensor 132. The first image sensor 131 and the second image sensor 132 can be respectively fixed on two opposite inner walls of the housing 10, and the size of the camera module 100 in the optical axis Z direction of the lens group 120 is relatively compact, so that the compactness of the whole structure can be improved, and the miniaturization of the whole structure is facilitated. The number of the image sensors can be more than two, and the arrangement mode is not limited. In one possible embodiment, the plurality of image sensors may be arranged in a circumferential direction around the optical axis.

In addition to the above embodiments, as shown in fig. 1, the light inlet 112 is provided on the wall of the housing 110. The camera module 100 further includes a second light path changing element 160. The second optical path changing element 160 is disposed inside the housing 100 on the other side of the lens group 120 facing away from the first optical path changing element 140, i.e., on the object side of the lens group 120. The second optical path changing element 160 is a right-angled edge, and has a light incident surface 161 and a light emitting surface 162 perpendicular to each other, wherein the light incident surface 161 is disposed to face the light incident hole 112 and parallel to the optical axis Z, the light emitting surface 162 faces the lens assembly 120, and the light emitting surface 162 is perpendicular to the optical axis Z. By the above means, the camera module 100 is formed as a periscopic camera module having different zoom magnifications.

The periscopic camera module of the above embodiment can be a common camera module without an anti-shake function, and can also be a camera module with an optical anti-shake function.

In order to realize the optical anti-shake function, the camera module 100 further includes a first anti-shake mechanism and a second anti-shake mechanism, which are respectively used for realizing the first direction anti-shake function and the second direction anti-shake function. Specifically, as shown in fig. 1, in the camera module 100, the first-direction anti-shake function is realized by rotating the second optical path changing element 160; the second-direction anti-shake function is achieved by moving the lens group 120.

The posture of the camera module 100 shown in fig. 4 is a side view of the camera module 100 and illustrates the directions of the X, Y, Z coordinate axes, the Z axis coinciding with the optical axis Z of the lens group 120. The first direction anti-shake means that the second optical path changing element 160 rotates around the first axis 171 perpendicular to the Z axis, and the rotation direction is shown by an arrow R1 in fig. 4, so that the position of the light incident surface 161 of the second optical path changing element 160 in the Y axis direction is finely adjusted, thereby compensating for the image blur caused by the shake of the camera module 100 in the Y axis direction. The Y-axis direction is the up-down direction, and is also the height direction of the electronic device when the handheld electronic device performs long-range shooting. Therefore, the first-direction anti-shake is realized by rotating the second optical path changing element 160, and the position of the light incident surface 161 in the Y-axis direction is adjusted. Specifically, the first shaft 171 and the light incident surface 161 are arranged to be parallel, that is, the axis of the first shaft 171 is parallel to the light incident surface 310. And it is understood that the second light path changing element 60 rotates about the first axis 171 in a first plane in the direction indicated by the arrow R1. The first-direction anti-shake function may be defined as a Y-axis direction anti-shake function.

The second direction anti-shake means to make the lens assembly 120 move in a translational manner along a second axis, i.e. the X-axis, so as to compensate for the image blur caused by the shake of the camera module 100 in the X-axis direction. Wherein, the X-axis direction is the direction vertical to the drawing surface, and the X-axis is vertical to the Z-axis. It will be appreciated that lens group 120 translates in a second plane perpendicular to the Z-axis, the second plane being perpendicular to the first plane. The second direction anti-shake function can be defined as the X-axis direction anti-shake function.

The first anti-shake mechanism is used to drive the second light path changing element 160 to rotate, so as to realize the anti-shake function in the first direction. In one possible embodiment, as shown in fig. 1, the first anti-shake and anti-shake mechanism includes a first shaft 171 rotatably connected to the second optical path changing element 160, a first magnetic element 172, and a second magnetic element 173, and the first shaft 171 is supported by the housing 110. The first magnetic member 172 is fixedly connected to the second light path changing member 160 directly or through an intermediate member, and the second magnetic member 173 is fixed to an inner wall of the housing 110. At least one of the first magnetic element 172 and the second magnetic element 173 is an electromagnetic unit, and the first magnetic element 172 and the second magnetic element 173 cooperate to drive the second optical path changing element 160 to rotate in a first plane, so that the position of the light incident surface 161 of the second optical path changing element 160 is changed in the Y-axis direction, thereby achieving the anti-shake in the first direction. The electromagnetic unit is a unit that generates magnetic force after being energized, such as an electromagnetic coil. In a specific embodiment, the first magnetic element 172 is a magnet, and the second magnetic element 173 is an electromagnetic coil, which are corresponding to each other. In other embodiments, the first magnetic element 172 and the second magnetic element 1732 may be arranged as follows: the first magnetic element 172 is an electromagnetic coil, and the second magnetic element 173 is a magnet; alternatively, both the first magnetic element 172 and the second magnetic element 173 are electromagnetic coils.

In the above embodiment, the second optical path changing element 160 is rotated by an electromagnetic driving method to realize Y-axis anti-shake, and the second optical path changing element 60 does not need to have a large translation distance in the Y-axis direction, and does not need to be provided with a translation mechanism having a large size in the Y-axis direction, so that the Y-axis anti-shake function is realized and the camera module is favorably thinned. In other embodiments, the second optical path changing element 160 may be driven by a shape memory alloy technique, a stepping motor, a piezoelectric motor, or the like, as long as the second optical path changing element 160 can be rotated.

As shown in fig. 1, the second anti-shake mechanism 180 is used to drive the lens assembly 120 to move in a translational manner. In a specific arrangement, the driving mechanism may be arranged to drive the lens assembly 120 to translate in the X-axis direction, so as to compensate for image blur caused by shaking of the camera module 100 in the X-axis direction. The type of the driving mechanism is not limited as long as the lens group 120 can be driven to translate in the X-axis direction to compensate for image blur caused by shaking of the camera module 100 in the X-axis direction. For example, the drive mechanism may be a linear motor, a solenoid, or the like.

As shown in fig. 1, based on the above embodiment, the camera module 100 may further include a second imaging module 20. The first imaging module 10 is configured as a telephoto imaging module, and the second imaging module 20 is configured as a wide-angle imaging module. The first imaging module 10 is a long focus imaging module, and has the characteristics of small viewing angle, low pixel and long focal length. The second imaging module 20 is a wide-angle imaging module, and has the characteristics of a large viewing angle, high pixels and a short focal length. The concepts of wide and tele are known per se to those skilled in the art and will not be described in further detail herein.

Specifically, the second imaging module 20 is disposed on one side of the first imaging module 10, wherein the second imaging module 20 may have an independent housing 201, and the lens group 202 and the third image sensor 203 are disposed in the housing 201. The housing 201 and the case 110 are fixed together to form the camera module 100 having the dual lenses. In addition, the lens group 202 and the third image sensor 203 of the second imaging module 20 may also be disposed in the housing 110.

In the conventional technology, a wide-angle imaging module and a telephoto imaging module are used in a matched manner, and only one similar optical zoom magnification can be realized. The camera module 100 of the above embodiment uses the wide-angle imaging module, i.e. the second imaging module 20, to shoot at a normal distance, and when a long-distance scene needs to be shot, for example, a tree in a long distance is closed up, the camera module can be switched to the telephoto imaging module, i.e. the first imaging module 10. By switching the first imaging module 10 and the second imaging module 20, optical zooming, i.e. optical-like zooming, is simulated. The first imaging module 10 has two different zoom magnifications, and therefore, the first imaging module 10 and the second imaging module 20 are used in combination, so that two different optical zoom magnifications can be realized, and the optical zoom lens has obvious advantages compared with the optical zoom lens in the conventional technology. Moreover, when the number of the image sensors of the first imaging module 10 is larger, more different optical zoom magnifications can be realized.

An embodiment of the utility model also provides an electronic equipment, including the camera module 100 of any preceding embodiment. The electronic device can be a mobile phone, a tablet and other intelligent mobile terminals, and can also be a camera device such as a digital camera.

In the electronic device of the embodiment, the first optical path changing element 140 enables the light emitted from the lens group 120 to be emitted to different image sensors, so as to switch different equivalent focal lengths, thereby achieving different zoom magnifications. In the zooming process, the same lens group 120 is used, and compared with the traditional technology, different lens groups are needed, so that the internal structure of the camera module is simplified.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only represent some embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
