Description

Imaging module, terminal equipment and zooming method

Technical Field

The embodiment of the invention relates to the technical field of imaging, in particular to an imaging module, terminal equipment and a zooming method.

Background

With the rapid development of communication technology, the use of terminal devices such as mobile phones and tablet computers is more and more common. At present, the shooting function becomes a standard function on the terminal equipment. In order to achieve a good photographing effect, terminal devices that can perform optical zooming in a small range (e.g., twice or three times) are increasingly widely used.

Generally speaking, in order to realize optical zooming of a terminal device, a plurality of lenses with different focal lengths need to be arranged in the terminal device, and a user can select a corresponding lens to work according to actual requirements. It can be seen that the optical zoom of the terminal device is realized by simply overlapping a plurality of lenses, so the cost is higher, and the space occupied by the lenses is larger.

Disclosure of Invention

The embodiment of the invention provides an imaging module, terminal equipment and a zooming method, and aims to solve the problems that the existing imaging module is high in cost and large in occupied space of a lens.

In order to solve the technical problem, the invention is realized as follows:

in a first aspect, an embodiment of the present invention provides an imaging module, including:

a lens;

a photosensitive element for receiving light;

a plurality of optical structures having different focal lengths, each of said optical structures being switchable between an operative position and an inoperative position;

the driving mechanism is connected with the optical structures and is used for driving the optical structures to switch between the working position and the non-working position;

when the optical structure is switched to the working position, the optical structure projects the light rays shot into the lens to the photosensitive element.

In a second aspect, an embodiment of the present invention provides a terminal device, including the imaging module described above, where the imaging module is installed in a housing of the terminal device.

In a third aspect, an embodiment of the present invention provides a zooming method, which is applied to the imaging module described above, where the zooming method includes:

determining whether a preset zooming condition is satisfied;

and under the condition that a preset zooming condition is met, controlling a driving mechanism in the imaging module to drive a plurality of optical structures in the imaging module to switch between a working position and a non-working position.

In the imaging module provided by the embodiment of the invention, based on the driving mechanism, the plurality of optical structures can be switched between the working position and the non-working position, when any optical structure is switched to the working position, the optical structure can project light rays shot into the lens to the photosensitive element, and the photosensitive element can perform imaging based on the projected light rays. Thus, the optical structure and the lens in the working position can form an optical transmission structure with a focal length which is the sum of the focal length of the optical structure and the focal length of the lens in the working position. Because including a plurality of optical structures of focus difference each other in the imaging module, and every optical structure homoenergetic switches over to operating position, so a plurality of optical structures and camera lens can constitute a plurality of optical transmission structures of focus difference each other, that is to say, imaging module can have a plurality of optional focuses. Under the condition that actuating mechanism switches the optical structure who is in operating position, the focus that the formation of image module during operation used can change, and like this, terminal equipment can realize many gears optics and zoom.

It can be seen that, in the embodiment of the present invention, because the imaging module of the terminal device includes the plurality of optical structures with different focal lengths and the driving mechanism, the optical zooming of the terminal device can be realized by switching the optical structure at the working position through the driving mechanism, and the optical zooming does not need to be overlapped through a plurality of lenses, compared with the prior art, the embodiment of the present invention can realize the optical zooming of the terminal device at a lower cost, and further, the embodiment of the present invention can avoid the excessive occupation of the lenses to the space.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present 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.

Referring to fig. 1 and 2, schematic structural diagrams of an imaging module according to an embodiment of the present invention are shown. Alternatively, the imaging module may be installed in the housing 1 of the terminal device, so that the housing 1 may protect the imaging module.

As shown in fig. 1 and 2, the imaging module includes: a lens 21, a photosensitive element 23, an optical structure 25 and a driving mechanism.

Wherein the position and focal length of the lens 21 are fixed.

Generally, the terminal device further includes at least one of a front camera system and a rear camera system, and a screen 5; the light paths of the front camera system and the rear camera system are different. The lens 21 is a lens in a front camera system in the case where the relative position of the lens 21 to the screen 5 is the condition shown in fig. 1; when the relative position of the lens 21 and the screen 5 is the case shown in fig. 2, the lens 21 is a lens in a rear camera system.

The photosensitive element 23 is used for receiving light. Wherein the photosensitive element 23 may have a photosensitive surface 230.

It should be noted that the photosensitive element 23 is a core element for implementing imaging, and the photosensitive element 23 may be a Complementary Metal-Oxide-Semiconductor (CMOS) element, of course, the type of the photosensitive element 23 is not limited thereto, and may be determined specifically according to an actual situation, and the embodiment of the present invention is not limited thereto.

The number of optical structures 25 is plural (i.e., at least two), the focal lengths of the plural optical structures 25 are different from each other, and each optical structure 25 is switchable between an operating position and a non-operating position.

The number of the optical structures 25 may be three, four, six, or eight, of course, the number of the optical structures 25 is not limited thereto, and may be determined according to actual situations, which is not limited in this embodiment of the present invention.

A driving mechanism connected to the plurality of optical structures 25 for driving the plurality of optical structures 25 to switch between the operative position and the inoperative position; when the optical structure 25 is switched to the working position, the optical structure 25 projects the light rays shot into the lens 21 to the photosensitive element 23.

Alternatively, each optical structure 25 may be a concave mirror, so that the structure of the optical structure 25 is very simple and the installation operation is very convenient. In actual operation, when the concave mirror is switched to the operating position, the concave mirror can directly project the light rays shot into the lens 21 to the photosensitive surface 230 of the photosensitive element 23 by reflecting the light rays.

Of course, the optical structure 25 is not limited to a concave mirror. For example, the optical structure 25 may be a convex lens, etc., and it is only necessary to ensure that the optical structure 25 can change the transmission direction of the light rays shot into the lens 21 when being switched to the working position, so as to project the light rays shot into the lens 21 onto the photosensitive surface 230 of the photosensitive element 23.

In the imaging module according to the embodiment of the present invention, based on the driving mechanism, the plurality of optical structures 25 may be switched between the working position and the non-working position, when any of the optical structures 25 is switched to the working position, the optical structure can project the light rays that are taken into the lens 21 to the photosensitive element 23, and the photosensitive element 23 may perform imaging based on the projected light rays. Thus, the optical structure 25 and the lens 21 in the operating position can constitute an optical transmission structure with a focal length that is the sum of the focal length of the optical structure 25 and the focal length of the lens 21 in the operating position. Because the imaging module includes a plurality of optical structures 25 with different focal lengths, and each optical structure 25 can be switched to the working position, the plurality of optical structures 25 and the lens 21 can form a plurality of optical transmission structures with different focal lengths, that is, the imaging module can have a plurality of selectable focal lengths. In the case that the driving mechanism switches the optical structure 25 in the working position, the focal length used when the imaging module works may change, so that the terminal device can realize multi-stage optical zooming.

It can be seen that, in the embodiment of the present invention, since the imaging module of the terminal device includes the plurality of optical structures 25 with different focal lengths and the driving mechanism, the optical zooming of the terminal device can be realized by switching the optical structures 25 located at the working position through the driving mechanism, and the optical zooming does not need to be overlapped through the plurality of lenses 21, compared with the prior art, the embodiment of the present invention can realize the optical zooming of the terminal device at a lower cost, and can also avoid excessive occupation of the lenses 21 on space.

Alternatively, as shown in fig. 3 to 6, there are two lenses 21, two lenses 21 are disposed at intervals, and a plurality of optical structures 25 are disposed between the two lenses 21, and when the optical structures 25 are switched to the working position corresponding to any one of the lenses 21, the optical structures 25 project the light rays shot into any one of the lenses 21 to the photosensitive element 23.

One of the two lenses 21 may be a lens in a front camera system (for example, the lens on the left side in fig. 3 to 6, which will be referred to as the left lens for short in the following description), and the other of the two lenses 21 may be a lens in a rear camera system (for example, the lens on the right side in fig. 3 to 6, which will be referred to as the right lens for short in the following description), and each optical structure 21 is located between the left lens and the right lens.

In this embodiment, as shown in fig. 3, when the optical structure 25 with the focal length f1 is switched to the working position corresponding to the left lens, the other optical structures 25 are all in the non-working position corresponding to the left lens, and the optical structure 25 with the focal length f1 can project the light rays shot into the left lens to the light sensing surface 230 of the light sensing element 23, so as to realize the imaging of the front camera system. As shown in fig. 4, when the optical structure 25 with the focal length f2 is switched to the working position corresponding to the left lens, the remaining optical structures 25 are all in the non-working position corresponding to the left lens, and the optical structure 25 with the focal length f2 can project the light rays shot into the left lens to the light sensing surface 230 of the light sensing element 23, so as to realize the imaging of the front camera system.

Similarly, as shown in fig. 5, when the optical structure 25 with the focal length f1 is switched to the working position corresponding to the right lens, the remaining optical structures 25 are all in the non-working position corresponding to the right lens, and the optical structure 25 with the focal length f1 can project the light rays shot into the right lens to the light sensing surface 230 of the light sensing element 23, so as to realize the imaging of the rear camera system. As shown in fig. 6, when the optical structure 25 with the focal length f2 is switched to the working position corresponding to the right lens, the remaining optical structures 25 are all in the non-working position corresponding to the right lens, and the optical structure 25 with the focal length f2 can project the light rays shot into the right lens to the light sensing surface 230, so as to realize the imaging of the rear camera system.

It can be seen that, in this embodiment, through the arrangement of the two lenses 21, namely the left lens and the right lens, the imaging of the two systems, namely the front camera system and the rear camera system, can be realized only by arranging the photosensitive element 23 in the terminal device, so that not only can the space in the terminal device be saved, so as to enable the space in the terminal device to be expandable, but also the number of interfaces required to be arranged in the terminal device can be reduced as much as possible, thereby effectively reducing the cost and the system complexity of the terminal device.

Alternatively, as shown in fig. 1-6, a plurality of optical structures 25 are connected in sequence to form a ring structure;

the drive mechanism is configured to drive the ring structure to rotate to switch one of the plurality of optical structures 25 to the operating position.

The plurality of optical structures 25 may be connected by welding, bonding, or the like to form a ring structure by connection. In particular, the annular structure may be a multi-faceted cylindrical structure. In particular, the drive mechanism may be a rotating electrical machine, by which the rotation of the ring structure may be realized in particular.

In this embodiment, only the driving mechanism is required to drive the ring structure to rotate, the optical structure 25 at the working position can be switched, and the optical zooming of the terminal device can be successfully realized.

Alternatively, the ring-shaped structure is fixedly provided with a central axis 27 as shown in fig. 1 to 7, and the central angle of each optical structure 25 with respect to the central axis 27 is the same;

a drive mechanism is coupled to the central shaft 27 to rotate the central shaft 27.

Specifically, the plurality of optical structures 25 included in the imaging module may be specifically 6 concave mirrors shown in fig. 7, and the focal lengths of the 6 concave mirrors may be f1 to f6, respectively. In the annular structure formed by connecting the 6 concave mirrors in sequence, the reflecting surface of each concave mirror faces outwards (i.e. away from the central axis 27), and the central angle (i.e. α 1 to α 6) of each concave mirror relative to the central axis 27 can be 60 degrees, that is, the 6 concave mirrors are divided into 360 degrees in half.

In this embodiment, the driving mechanism may be a rotating electrical machine with an output shaft fixed thereto, and the central shaft 27 may be fixedly connected with the output shaft. In this way, under the condition that the rotating motor drives the output shaft to rotate, the central shaft 27 can rotate along with the output shaft, and accordingly, the optical structure 25 in the working position can be switched, so that the optical zooming of the terminal device can be realized conveniently. In addition, the central angles of the optical structures 25 relative to the central axis 27 are the same, so that the chance of the optical structures 25 being in the operative position is as balanced as possible.

Alternatively, a plurality of optical structures 25 are connected in series to form a linear structure;

the drive mechanism is configured to drive the linear structure to move to switch one optical structure 25 of the plurality of optical structures 25 to the operating position.

Wherein the plurality of optical structures 25 may be connected by welding, bonding, etc. to form a linear structure by the connection.

In this embodiment, the linear structure is driven to move only by the driving mechanism, the optical structure 25 at the working position can be switched, and the optical zooming of the terminal device can be successfully realized, so that the optical zooming operation of the terminal device is convenient to implement.

Optionally, the imaging module further comprises: the linear structure is movably arranged in the sliding rail and moves along the sliding rail. In this way, the slide rail can limit the moving range of the linear structure, and the linear structure does not undergo a large positional change in other directions than the installation direction of the slide rail.

Optionally, as shown in fig. 1 to 6, the imaging module further includes: a controller 29; wherein the controller 29 is electrically connected to the driving mechanism, and the controller 29 is configured to control the driving mechanism to drive the plurality of optical structures 25 to switch between the working position and the non-working position.

Among them, the controller 29 may also be referred to as a zoom controller.

It can be seen that, in the embodiment, the driving mechanism can be conveniently controlled in an electric control mode, so that the optical zooming of the terminal equipment is realized. It is of course also possible that the drive mechanism is controlled purely mechanically.

Alternatively, the controller 29 is configured to determine whether a preset zoom condition is satisfied, and control the driving mechanism to drive the plurality of optical structures 25 to switch between the operating position and the non-operating position if the preset zoom condition is satisfied.

It should be noted that the operation strategy of the controller 29 is various, and the following description is given by way of example.

In one embodiment, the controller 29 is specifically configured to:

in the case where a zoom control instruction input by the user is received, it is determined that the preset zoom condition is satisfied, and the driving mechanism is controlled to switch the optical structure 25 indicated by the zoom control instruction to the operating position.

Specifically, in the case shown in fig. 1, the concave mirror with focal length F1 is in the working position, and the concave mirror with focal length F1 can reflect the light rays that are taken into the lens 21 (assuming that the focal length is F) to the photosensitive surface 230 of the photosensitive element 23, and at this time, the concave mirror with focal length F1 and the lens 21 constitute an optical transmission structure with focal length F + F1.

If optical focusing is required due to the distance of an object to be photographed, a user may input a zoom control instruction to the terminal device through a touch screen operation, and the zoom control instruction may be used to instruct to switch a concave mirror of another focal length (for example, a concave mirror of focal length f 2) to the operating position. Next, a zoom control command can reach the controller 29, at which time, the controller 29 may determine that the preset zoom condition is satisfied, and drive the ring structure to rotate through the driving mechanism, so as to switch the concave mirror with the focal length F2 to the working position according to the instruction of the zoom control command, at which time, the concave mirror with the focal length F2 and the lens 21 form an optical transmission structure with the focal length F + F2, and the optical zoom of the terminal device is successfully achieved.

In this embodiment, the controller 29 can switch the optical structure 25 to the working position according to the instruction of the zoom control instruction input by the user, so as to better ensure the imaging effect of the terminal device.

In another embodiment, the controller 29 is electrically connected to the photosensitive element 23 and the driving mechanism,

the controller 29 is specifically configured to:

controlling the driving mechanism to sequentially switch each optical structure 25 to the working position;

respectively obtaining preview images generated by the photosensitive elements 23 when the optical structures 25 are in the working positions;

determining a preview image with the best preview effect in the preview images;

and under the condition that the optical structure 25 corresponding to the determined preview image is not at the working position currently, determining that a preset zooming condition is met, and controlling the driving mechanism to switch the optical structure 25 corresponding to the determined preview image to the working position.

In specific implementation, as shown in fig. 8, a user first selects to use the front-facing camera system for imaging or to use the rear-facing camera system for imaging through a touch screen operation, and the terminal device determines an object selected by the user from the front-facing camera system and the rear-facing camera system.

Next, the controller 29 may control the driving mechanism to rotate the ring structure of fig. 7 by one rotation, so that the concave mirrors having the focal lengths f1 to f6 can be sequentially switched to the operating positions. When any concave reflector is in a working position, the terminal equipment can carry out automatic focusing and adopt a set algorithm to carry out fine focusing. Thereafter, the controller 29 may acquire the preview images generated by the photosensitive elements 23 when the concave mirrors are at the working positions, respectively, and compare the acquired preview images to determine a preview image with the best preview effect. In the case where the concave mirror corresponding to the preview image with the best preview effect is not currently located at the operating position, the controller 29 may determine that the preset zoom condition is satisfied, and control the driving mechanism to switch the concave mirror to the operating position.

Specifically, if the comparison shows that the controller 29 determines that the preview effect of the preview image generated by the photosensitive element 23 is the best when the concave mirror with the focal length f3 is in the working position, which indicates that in the present case, the best imaging effect can be obtained by placing the concave mirror with the focal length f3 in the working position, and therefore, the controller 29 can switch the concave mirror with the focal length f3 to the working position.

In this embodiment, the controller 29 can automatically determine the optical structure 25 that can achieve the best imaging effect from the optical structures 25 according to the image preview effect when the different optical structures 25 are in the working position, and place the optical structure 25 in the working position, so that the imaging effect of the terminal device can be better ensured.

It can be seen that, in this embodiment, the controller 29 may perform corresponding control operations when the preset zoom condition is satisfied, so as to better ensure the imaging effect of the terminal device.

In summary, compared with the prior art, the present embodiment can realize the optical zoom of the terminal device at a lower cost, and can also avoid the excessive occupation of the lens 21 on the space.
