Detailed Description

Fig. 1 is a schematic structural diagram of a terminal device according to an embodiment of the present application. Fig. 2 is a schematic structural diagram of an image pickup device in terminal equipment according to an embodiment of the present application. As shown in fig. 1 and fig. 2, the terminal device provided in this embodiment specifically includes a body 10 and an image pickup device 20, where the image pickup device 20 includes an image sensor 1 and a reflector 2, the image sensor 1 is disposed on the body 10, an incident light side of the reflector 2 is exposed outside the body 10, an emergent light side of the reflector 2 faces the image sensor 1, and the reflector 2 can rotate to different directions facing the body 10, so that the image sensor 1 collects images from different directions of the body 10.

The terminal device can be different devices such as a mobile phone, a tablet computer and a personal digital assistant. In this embodiment, a terminal device is taken as an example for explanation. Specifically, the terminal device includes a main body 10 and a camera device 20 disposed on the main body 10, and the main body 10 is a main structure and a functional main body of the terminal structure, and may specifically include a housing, and a screen, a processor, various functional circuits, and other components disposed inside the housing. The camera device 20 is disposed on the main body 10 and can capture external images and perform photographing and photographing functions.

Specifically, the imaging device 20 includes different components such as the image sensor 1 and the mirror 2. The image sensor 1 is an electronic device that converts an optical image from the outside into an electrical signal having a certain proportional relationship with the image by using a photoelectric conversion function of a photoelectric device. Currently, the image sensor 1 may be a Complementary Metal-Oxide-Semiconductor (CMOS) sensor or other different types. Since the image sensor 1 is composed of a relatively precise photoelectric device, the image sensor 1 can be disposed inside the main body 10 of the terminal device, and the image sensor 1 is shielded and protected by the structure of the main body 10 itself.

In order to transmit light outside the terminal device to the light-sensing surface of the image sensor 1, a reflector 2 is disposed in the image capturing device 20, and the reflector 2 can receive external light from the light-entering side of the reflector 2 and emit the light from the light-emitting side. At this time, by setting the structure and the direction of the reflector 2, the light incident side 21 of the reflector 2 is exposed to the outside of the body 10, and the light emitting side 22 of the reflector 2 faces the image sensor 1, so that the image sensor 1 collects light and images from the outside. At this time, since the mirror 2 itself has the ability to reflect light rays to different directions, the mirror 2 and the image sensor 1 together constitute a structure similar to a periscope. Thus, even if the image sensor 2 is located inside the body 10, it can still receive and collect external light and images normally.

Here, the mirror 2 is not fixed with respect to the body 10 of the terminal device, but can be rotated to different directions with respect to the body 10. With the rotation of the reflector 2, the light incident side 21 of the reflector 2 is correspondingly turned to different directions and positions, and at this time, the light beams from different positions can be irradiated into the camera device 20 through the light incident side 21 of the reflector 2 and reach the light sensing surface of the image sensor 1 under the reflection of the reflector 2, so that the image sensor 1 can acquire the image from the direction. By rotating the reflector 2, the image sensor 1 in the terminal device can acquire and shoot images from different directions outside the terminal device body 10. Compared with the prior art, the scheme that images of the terminal equipment in different directions are shot through different cameras (a front camera and a rear camera) respectively is adopted, the method can finish the shooting of the images of the terminal equipment in different directions only through the same image sensor 1 in the terminal equipment, so that the structure is effectively simplified, the cost is reduced, and the image sensor 1 in the camera device 20 can have higher resolution and stronger parameters; meanwhile, when the camera device 20 shoots images in different directions, only the reflector 2 needs to be turned to different directions, and other elements, such as the lens or the optical anti-shake assembly, can maintain the same state, so that when the terminal device shoots images in different directions, the anti-shake function can be realized through the optical anti-shake assembly, or the lens angle in a specific range can be realized through focusing of the lens, and thus the function of the camera device 20 cannot be weakened due to the change of shooting directions relative to the terminal device body 10.

Wherein, optionally, the body 10 of the terminal device may include a screen 140, and the reflector 2 may be rotated to the same side of the screen 140 and the back side of the screen 140. The camera device 20 can thus be used as a front camera or a rear camera of the terminal.

Various possible configurations of the image pickup device 20 in the terminal apparatus and various possible arrangements of the image pickup device 20 with respect to the main body 10 will be described in detail below.

As an alternative embodiment, the reflector 2 has a light-reflecting surface 22, and the light-reflecting surface 22 forms an angle with the focal plane of the image sensor 1, so as to reflect the light incident from the light-incident side 21 of the reflector 2 to the light-emitting side 23 of the reflector 2.

The image sensor 1 may be accommodated inside the body 10 of the terminal device, and the light-sensing surface of the image sensor 1 may face the front of the outer surface of the body 10, for example, perpendicular to the normal direction of the outer surface of the body 10. In order to reflect and transmit the external light to the light-sensing surface of the image sensor 1, the reflector 2 may be partially or entirely disposed outside the main body 10 of the terminal device. And the reflector 2 may include a light reflecting surface 22 for reflecting light, and the structure of the reflector 2 will be described in detail below:

fig. 3 is a schematic optical path diagram of a first mirror structure provided in an embodiment of the present application. In a first mirror configuration, as shown in fig. 1 to 3, the mirror 2 comprises a light-reflecting surface 22 inside. The mirror 2 and the image sensor 1 have different height positions with respect to the normal direction of the outer surface of the body 10. The reflecting surface 22 of the reflector 2 may be disposed obliquely and form an angle with the focal plane of the image sensor 1, so that external light enters the reflector 2 from the light entrance side 21 of the reflector 2, and then irradiates the reflecting surface 22 and is reflected to another direction by the reflecting surface 22. By adjusting the angle of the reflector 2, a certain included angle is formed between the reflective surface 22 of the reflector 2 and the focal plane of the image sensor 1, so that the external incident light is reflected to the image sensor 1 on the light emitting side 23 of the reflector 2 through the reflector 2.

Because the light-sensing surface of the image sensor 1 faces the front of the outer surface of the main body 10, the angle between the light-reflecting surface 22 of the reflector 2 and the focal plane of the image sensor 1 may be about 45 °. In this way, the direction in which the light incident side 21 of the reflecting mirror 2 faces is substantially parallel to the light sensing surface of the image sensor 1, and thus light and an image incident in parallel to the light sensing surface of the image sensor 1 can be reflected onto the image sensor 1. At this time, an included angle of about 90 degrees is formed between the light incident from the light incident side 21 of the reflector 2 and the light emergent from the light emergent side 23 of the reflector 2, that is, the reflector 2 reflects the light from the outside and then irradiates the light onto the image sensor 1 perpendicular to the original direction of the light. The direction of the optical axis of the mirror 2 is generally along the direction of the line from the light entrance side 21 to the light exit side 23 of the mirror 2.

Fig. 4 is a schematic optical path diagram of a second mirror structure provided in an embodiment of the present application. As shown in fig. 4, in the second reflector structure, when the reflector 2 reflects the external light onto the image sensor 1 through the reflective surface 22, optionally, two reflective surfaces 22 of the reflector 2 may be provided, and the two reflective surfaces 22 have the same orientation and are staggered from each other by a certain distance. At this time, the two reflecting surfaces 22 of the reflector 2 may be disposed in the whole optical path of the image capturing device 20 from the light incident side 21 of the reflector 2 to the light exiting side 23 of the reflector 2, the first reflecting surface 22 reflects the light incident from the light incident side 21 of the reflector 2 to the second reflecting surface 22, and the second reflecting surface 22 reflects the light from the first reflecting surface 22 to the light exiting side 23 of the reflector 2 and irradiates the light sensing surface of the image sensor 1. The specific optical path is shown in fig. 4. At this time, an included angle is formed between the two reflecting surfaces 22 of the reflector 2 and the focal plane of the image sensor 1, and the light-sensitive surface of the image sensor 1 is substantially perpendicular to the light-incident side 21 of the reflector 2, so that after external light enters the reflector 2, the emergent direction of the external light is still the same as or parallel to the incident direction through the reflection of the two reflecting surfaces 22, and a certain displacement exists between the emergent light and the incident light, so that the light incident from the light-incident side 21 of the reflector 2 located outside the body 10 is irradiated onto the image sensor 1 located inside the body 10. At this time, the light beam is reflected for 2 times from the inside of the reflector 2 to the light-emitting side 23 of the reflector 2, and the propagation direction of the light beam is turned twice, wherein the propagation direction of the light beam inside the reflector 2, or the direction of the optical axis of the reflector 2, is also along the light-emitting side 23 of the reflector 2 to the light-emitting side 21 of the reflector 2.

For convenience of description, the mirror 2 in the imaging device 20 will be described as an example of a first mirror structure.

When the image pickup device 20 uses the reflector 2 to transmit light, the external light is irradiated on the image sensor 1. In order to allow the photographing device to photograph images located in different directions around the main body 10, the photographing device 20 may further include a first rotating shaft 24, and the reflector 2 may rotate around the first rotating shaft 24, so that the light incident side of the reflector 2 rotates to different directions toward the main body 10.

At this time, the first rotating shaft 24 can enable the reflector 2 to be rotatably connected with other structures of the terminal device, such as the body 10, or an independent bracket, so that the reflector 2 can be turned to different directions only by driving the reflector 2 to rotate, and the light incident side 21 of the reflector 2 correspondingly faces to different directions of the body 10, and light rays from different directions around the body 10 irradiate into the reflector. Thus, the first rotating shaft 24 is used to rotatably connect the reflector 2, the camera device 20 has a simpler structure, and the movement of the reflector 2 is simpler.

The first shaft 24 may have a variety of different configurations and styles, among others. For example, in order to prevent the first rotating shaft 24 from being blocked in the propagation path of the light and affecting the image quality of the image capturing device 20, the first rotating shaft 24 may be in the form of a trunnion and disposed at the side of the reflector 2, so that the light reflected by the reflector 2 is not blocked by the first rotating shaft 24. Alternatively, a bracket may be provided outside the mirror 2, and the first rotation shaft 24 may be connected to the bracket to rotate the mirror 2.

In particular, the first shaft 24 may have a plurality of different directions of extension. For example, in an alternative configuration, a line drawn between the light-entry side 21 of the mirror 2 and the light-exit side 23 of the mirror 2 would be perpendicular to the first axis of rotation 24.

At this time, a connection line between the light incident side 21 of the reflector 2 and the light emitting side 23 of the reflector 2 is substantially the optical axis direction of the reflector 2, and when the first rotation axis 24 is perpendicular to the connection line, the reflector 2 can rotate around the first rotation axis 24, so that the light incident side 21 and the light emitting side 23 face different directions. Fig. 5 is a schematic view of a first rotation structure of the mirror rotating around the first rotation axis in the embodiment of the present application. Fig. 6 is a schematic structural diagram of a first rotating structure according to an embodiment of the present disclosure, in which a mirror is located at a first position. Fig. 7 is a schematic structural diagram of a first rotating structure according to an embodiment of the present application, in which a mirror is located at a second position. As shown in fig. 5 to 7, taking the case that the focal plane of the image sensor 1 is perpendicular to the connecting direction between the light incident side 21 and the light emergent side 23 of the reflector 2, when the reflector 2 is located at the first position, the light incident side 21 of the reflector faces the first direction, and the light is incident from the direction a, and the light emergent side 23 of the reflector 2 faces the image sensor 1; when the reflector 2 rotates around the first rotating shaft 24 to the second position, the light incident side 21 of the reflector 2 rotates to the direction facing the image sensor 1, i.e. the light emitting side direction at the first position; the light exit side 23 of the mirror 2 is correspondingly rotated to a second direction opposite to the first direction and serves as the light entrance side of the mirror 2 at a second position, thereby receiving light incident from the direction B. By rotating the mirror 2 about the first rotation axis 24, the light incident side 21 of the mirror 2 faces two opposite directions, so that the image capturing device 20 can capture images from the two different directions.

The first rotation shaft 24 may be outside the reflector 2 or may be overlapped with the reflector 2. However, if the first rotating shaft 24 is located outside the reflector 2, the reflector 2 may occupy a large rotation space when rotating, resulting in a large structural size of the image capturing device 20. In order to make the structure of the camera device 20 and the whole terminal device compact, the first rotating shaft 24 may alternatively pass through the reflecting mirror 2.

In this way, since the first rotating shaft 24 is located on the reflector 2 and overlaps with the position of the reflector 2, when the reflector 2 rotates around the first rotating shaft 24, it is equivalent to self-rotation, and therefore, when the reflector 2 rotates, the formed rotating profile occupies only a small space, and the image pickup device 20 can have a compact size.

In the case of the above-mentioned arrangement of the first rotating shaft 24, since the light incident side 21 and the light emitting side 23 of the reflecting mirror 2 are interchanged after the reflecting mirror 2 rotates around the first rotating shaft 24, the rotation angle of the reflecting mirror 2 with respect to the first rotating shaft 24 may be about 90 °, specifically, in fig. 6 to 7, after the reflecting mirror 2 rotates 90 ° counterclockwise around the first rotating shaft 24, an image in the other direction may be captured.

At this time, optionally, the first direction may be a front direction of the terminal device (for example, a direction that the screen faces), and the second direction may be a back direction of the terminal device, so that when the reflector 2 rotates around the first rotating shaft 24 and the light incident side 21 of the reflector 2 faces the first direction and the second direction, respectively, it is equivalent to the light incident side 21 of the reflector 2 faces the front of the body 10 or faces the back of the body 10. At this time, the camera device 20 can be used as a front camera or a rear camera of the terminal device according to different orientations of the light incident side 21 of the reflector 2, and it is no longer necessary to separately provide the front camera and the rear camera.

In yet another alternative arrangement, the first axis of rotation 24 may extend along a line between the light entry side 21 of the mirror 2 and the light exit side 23 of the mirror 2.

At this time, the direction of the first rotation axis 24 is kept coincident or nearly coincident with the optical axis direction of the image pickup device 20. Thus, when the mirror 2 is rotated about the first axis of rotation 24, the overall relative position of the light-in side 21 of the mirror 2 and the light-out side 23 of the mirror 2 remains unchanged, except for the change in orientation of the light-in side 21 of the mirror 2. Fig. 8 is a schematic view of a second rotation structure of the mirror rotating around the first rotation axis in the embodiment of the present application. Fig. 9 is a schematic structural view of a second rotating structure of the present embodiment in which a mirror is located at a first position. Fig. 10 is a schematic structural view of a second rotating structure of the present application with the mirror located at the second position. Specifically, as shown in fig. 8 to 10, still taking the case that the focal plane and the optical axis of the image sensor 1 are perpendicular to each other as an example, the first rotating shaft 24 is disposed perpendicular to the focal plane or the light-sensing surface of the image sensor 1, and when the mirror 2 is located at the first position, the light-incident side 21 of the mirror 2 faces the first direction and receives the incident light from the first direction, i.e., the a direction; when the reflector 2 rotates around the first rotation axis 24 to the second position, the light incident side 21 of the reflector 2 faces a second direction opposite to the first direction and receives incident light from the second direction, i.e. the direction B. Regardless of the direction to which the light-incident side 21 of the mirror 2 is turned, the light-exiting side 23 of the mirror 2 faces the image sensor 1. Thus, with the rotation of the reflector 2, the image sensor 1 can collect and shoot images from different directions outside the body 10. Wherein the orientation between the first direction and the second direction may differ by 180 °.

Because the extending direction of the first rotating shaft 24 is perpendicular to the focal plane direction of the image sensor 1, when the reflector 2 rotates around the first rotating shaft 24, no matter which direction the light incident side 21 of the reflector 2 rotates to the circumferential direction (360 °) of the image pickup device 20, the reflector 2 can normally reflect the external light to the photosensitive surface of the image sensor 1, that is, the reflector 2 can rotate around the first rotating shaft 24 by 360 °. Accordingly, the image capturing device 20 can be used to capture images in different directions in the circumferential direction, not only in two specific directions, namely the first direction and the second direction. Compared with the former arrangement mode of the first rotating shaft 24, the first rotating shaft 24 and the focal plane of the image sensor 1 are vertically arranged, the reflector 2 rotates around the circumferential direction of the camera device 20, the camera device 20 can shoot images in different circumferential directions, and the shooting directions are more various.

In the same way as in the former structure, the first rotation shaft 24 may be outside the reflector 2 or may be coincident with the reflector 2. In order to make the structure of the camera device 20 and the whole terminal device more compact, optionally, when the first rotation axis 24 is perpendicular to the focal plane of the image sensor 1, the first rotation axis 24 may also pass through the mirror 2. At this time, the reflector 2 and the image sensor 1 are overlapped up and down in the normal direction of the outer surface of the body 10, and the first rotating shaft 24 passes through the reflector 2 and overlaps with the position where the reflector 2 is located, so that when the reflector 2 rotates around the first rotating shaft 24, the rotation is equivalent to the rotation around the connecting line between the reflector 2 and the image sensor 1, the light incident side 21 of the reflector 2 faces to different directions of the circumferential direction (360 °) of the image sensor 1, and the light emergent side 23 of the reflector 2 is always opposite to the image sensor 1.

Optionally, when the reflector 2 rotates around the first rotation axis 24, the light incident side 21 of the reflector 2 may face the front of the body 10 of the terminal device, or face the rear of the body 10, and correspondingly, the camera device 20 may be used as a front camera or a rear camera of the terminal device according to different orientations of the light incident side 21 of the reflector 2, so that the camera device 20 can meet the requirements of forward shooting and backward shooting of the terminal device.

The mirror 2 may have a variety of different configurations and forms in order to allow the mirror 2 to reflect light. For example, optionally, the reflector 2 may be a planar reflector, a mirror surface of the planar reflector may be used as the light reflecting surface 22 of the reflector 2, and different portions of the planar reflector may respectively form the light incident side 21 of the reflector 2 and the light exit side 23 of the reflector 2.

Wherein, optionally, the planar reflector may be a glass coated lens, or other reflector sheet material known to those skilled in the art.

Alternatively, the mirror 2 may be a prism. The prism is a transparent polyhedron, and when external light irradiates the prism, the refraction or reflection phenomenon of the light at the boundary of the prism is caused because the refraction index of the material of the prism is inconsistent with the refraction index of the external air. In order to reflect the external light, the reflector 2 may be a total reflection prism. At this time, the prism is a triangular prism, and the cross section of the prism may be an isosceles right triangle. When light rays are emitted from the right-angle side at one side of the cross section of the prism, the light rays can irradiate on the plane where the hypotenuse of the cross section of the prism is located; when the incident angle of the light is larger than a certain value, for example, larger than the critical angle, the total reflection can be generated on the plane where the hypotenuse is located, and the reflected light can be emitted from the right-angle side at the other side of the cross section of the prism.

In particular, when the reflector 2 is a prism, it can be made of optical glass or transparent optical material known to those skilled in the art.

In addition, the reflector 2 may be other optical reflection structures known to those skilled in the art, and is not limited herein.

Fig. 11 is a schematic diagram of a relative position between an image capturing apparatus and a main body according to an embodiment of the present application. As shown in fig. 11, in order to accommodate and mount the image sensor 1, the main body 10 is optionally provided with an accommodating cavity 11 having an opening 12, the image sensor 1 is disposed in the accommodating cavity 11, and the reflector 2 is located outside the opening 12 of the accommodating cavity 11. The reflector 2 can reflect light to the inside of the accommodating cavity 11 through the opening 12, so that the image sensor 1 located in the accommodating cavity 11 can collect external light and images. The accommodating cavity 11 may be formed by a housing of the main body 10, and the image sensor 1 is located inside the housing of the main body 10 and electrically connected to other circuit components in the main body 10, so as to implement an image capturing function.

At this time, by providing the accommodating cavity 11 on the body 10 and disposing the image sensor 1 inside the accommodating cavity 11, the components of the image sensor 1 in the image pickup device 20, such as the image sensor 1, can be buried or hidden inside the body 10, and only a part of the structure of the reflector 2 is exposed on the outer surface of the body 10. Therefore, the overall appearance of the terminal equipment is simpler; meanwhile, the reflector 2 located outside the accommodating cavity has an exposed surface exposed on the outer surface of the body 10, so that a better view field is provided, and images located in front of the body 10 or behind the body 10 can be conveniently shot.

The image sensor 1 located in the accommodating cavity 11 may have different positions and arrangements according to different structures of the reflector 2. As an optional structure, the light-sensing surface of the image sensor 1 faces the opening 12 of the accommodating cavity 11 and is disposed opposite to the light-emitting side of the reflector 2.

In order to reduce the size of the accommodating cavity 11, the light-sensing surface of the image sensor 1 may be aligned with the opening 12, such that the image sensor 1 may be parallel to the outer surface of the body 10, and the light-emitting side 23 of the reflector 2 may be opposite to the light-sensing surface of the image sensor 1. At this time, the accommodating chamber 11 has a small size in the depth direction, which is advantageous for keeping the terminal device in a compact size.

When the terminal device is a mobile phone, the body 10 is a cuboid and has a front side and a back side opposite to each other, and the front side can be used for setting a screen and displaying an image.

At this time, in order to allow the imaging device 20 to capture images from different directions outside the terminal device, the mirror 2 in the imaging device 20 needs to be exposed outside the body 10, and when the mirror 2 rotates, the mirror 2 cannot be shielded by the structure of the body 10 itself. At this time, as an alternative embodiment, the opening 12 of the receiving cavity 11 may be located at a side edge of the body 10 of the terminal device, and the direction of the opening 12 is toward an outer side of the edge of the body 10.

The image sensor 1 and other components in the image capturing device 20 are disposed inside the accommodating cavity 11, the light incident side 21 of the reflector 2 is exposed outside the opening 12, and the height of the light incident side 21 of the reflector 2 is higher than the lateral edge of the body 10, so that the body 10 is not shielded at the lateral side of the reflector 2. At this time, no matter which direction the reflector 2 rotates towards the body 10, the front of the light incident side 21 of the reflector 2 can normally receive the external light and perform imaging. The light incident side 21 of the reflector 2 may face one side of the lateral edge of the main body 10, for example, the light incident side 21 of the reflector 2 faces the front of the main body 10 and collects an image of the front of the main body 10, or faces the back of the main body 10 and collects an image of the back of the main body 10. Compared with the prior art that the front camera needs to be arranged on the side of the screen of the terminal device, namely, in the frame area of the terminal device, the camera device 20 is arranged on the side of the terminal device body 10, and the camera can not be arranged on the front frame of the terminal device, so that the size of the frame area of the terminal device can be reduced, and the screen occupation ratio of the terminal device is increased.

Correspondingly, since the opening 12 of the accommodating cavity 11 is located at the side edge of the body 10, the image sensor 1 is also disposed at the edge area of the body 10, and the light-sensing surface of the image sensor 1 faces the outer side of the edge of the body 10, so as to receive the light and the image reflected by the reflector 2.

In addition, in order to reduce the influence of the camera device 20 on the external shape of the body 10, as an alternative embodiment, the camera device 20 may be hidden inside the overall outline of the body 10, and the camera device 20 does not protrude out of the edge of the body 10, so that the body 10 can have a concise and beautiful external outline.

Specifically, fig. 12 is a schematic structural diagram of another terminal device provided in the embodiment of the present application. Fig. 13 is an enlarged schematic view at a in fig. 12. As shown in fig. 12 and 13, optionally, the body 10 is provided with a through hole 13 penetrating through the front and back surfaces of the body, and the through hole 13 is communicated with the opening 12, so that the reflector 2 of the image pickup device 20 can be disposed in the through hole 13, and the reflector 2 cannot be shielded by the body 10 no matter the reflector 2 rotates to the front surface of the body 10 or rotates to the back surface of the body 10, so that light can be guided into the image pickup device 20 through the reflector 2 and the opening 12 normally. Meanwhile, the body 10 can well protect and shield the reflector 2, and the reflector 2 is prevented from protruding out of the body 10.

It should be noted that the opening direction of the accommodating cavity 11 is applicable to the first reflector structure, that is, the reflector 2 includes a reflective surface 22 therein, and the direction of the outgoing light is perpendicular to the direction of the incoming light, and also applicable to the second reflector structure. When the opening 12 is located at the side edge of the body 10, since the reflector 2 includes two reflective surfaces 22 inside, and the outgoing light and the incoming light can be maintained in a parallel state, the image sensor 1 can be disposed parallel to the front surface of the body 10 or parallel to the back surface of the body 10.

At this time, since the image sensor 1 needs to have higher resolution and imaging quality, the photosensitive surface of the image sensor 1 needs to have a certain area and size, and when the first mirror structure is adopted, the photosensitive surface of the image sensor 1 is along the thickness direction of the body 10, so that the size of the photosensitive surface of the image sensor 1 affects the thickness of the terminal body 10. And the opening of the accommodating cavity is arranged at the side edge of the body 10, and when the reflector 2 comprises two reflecting surfaces 22, the light-sensitive surface of the image sensor 1 is parallel to the front surface or the back surface of the body 10, so the thickness of the body 10 is not influenced by the area of the image sensor 1, and the miniaturization and the thinning of the terminal equipment are facilitated.

In order to fix the reflector 2 and make the reflector 2 rotate to different directions relative to the body 10, the image capturing device 20 may further include a rotating base 6, the reflector 2 may be disposed on the rotating base 6, and the rotating base 6 may rotate relative to the body 10, so that the reflector 2 faces to different directions relative to the body 10.

Specifically, the rotating base 6 may be disposed outside the opening 12, and the rotating base 6 itself is a hollow structure to prevent the rotating base 6 from blocking the propagation of light. The rotation direction of the rotating base 6 is also around the first rotation axis 24, for example, the rotating base 6 can rotate around the circumference of the opening 12, or rotate around the first rotation axis 24 parallel to the image sensor 1, etc.

It will be appreciated by those skilled in the art that the rotating base 6 itself may be a split structure for achieving rotation relative to the body 10, for example, including a fixed portion fixedly connected to the body 10 and a movable portion rotatable relative to the fixed portion, with the mirror 2 being located on and rotatable with the movable portion. The specific structure of the rotating base 6 can refer to a rotating structure known to those skilled in the art, and will not be described herein.

In order to make the image capturing apparatus 20 achieve a rich shooting function, the image capturing apparatus 20 may further include a lens assembly 3, where the lens assembly 3 includes at least one lens 31, and the lens 31 is located on the light-sensing side of the image sensor 1.

Specifically, when the image sensor 1 collects an image of an external scene, imaging is generally performed through the lens assembly 3. The lens assembly 3 includes one or more transparent lenses 31, and a lens barrel 32 for supporting the lenses 31, so that external light can be imaged on the light-sensing surface of the image sensor 1 by refraction of the lenses 31.

The lenses 31 in the lens assembly 3 may be a plurality of lenses, and the plurality of lenses 31 are arranged in groups, so that different functions such as focusing and zooming can be realized by the lens assembly 3 by changing the relative positions of the different lenses 31.

At this time, the lens 31 of the lens assembly 3 is located on the photosensitive side of the image sensor 1, i.e. in front of the photosensitive surface, and the lenses 31 of the lens assembly 3 are sequentially arranged along the optical axis of the lens assembly 3. Since the reflector 2 in the image capturing device 20 only changes the light propagation direction, the reflector 2 and the lens assembly 3 can work together without affecting each other, thereby ensuring normal imaging of the image sensor 1.

Specifically, the lens assembly 3 and the mirror 2 may be located at different positions on the entire propagation optical path of the image pickup device 20. There are many different arrangements and positional relationships between the lens 31 and the reflector 2 in the lens assembly 3. Since the reflector 2 needs to be exposed outside the body 10, in order to fully utilize the space on the body 10, at least a portion of the lens 31 of the lens assembly 3 may be disposed between the light emitting side 23 of the reflector 2 and the image sensor 1.

Since the reflector 2 is partially or completely exposed to the outside of the body 10 and the image sensor 1 can be located inside the body 10, there is a relatively sufficient space between the light-emitting side 23 of the reflector 2 and the image sensor 1. And part or all of the lens 31 of the lens assembly 3 may be disposed in the area between the light exit side 23 of the mirror 2 and the image sensor 1.

Specifically, as an alternative arrangement, all the lenses 31 of the lens assembly 3 may be disposed between the light-emitting side 23 of the reflector 2 and the image sensor 1, as shown in fig. 2. The light-emitting side 23 of the reflector 2 may be opposite to the light-sensing surface of the image sensor 1, and the mirrors 31 are located in front of the image sensor 1. At this time, the lens assembly 3 and the image sensor 1 are both located on the light emitting side 23 of the reflector 2, so the lens assembly 3 can be located inside the body 10 of the terminal device, the space inside the body 10 can be used to dispose the lens assembly 3, the image sensor 1 and other components, and the part exposed outside the body 10 is only the whole or partial structure of the reflector 2. Therefore, the part of the camera device 20 protruding out of the body 10 is less, and the appearance of the terminal equipment is simpler and more beautiful.

As another alternative, a part of the lens 31 of the lens assembly 3 may be disposed on the light incident side 21 of the reflector 2. Fig. 14 is a schematic structural diagram of another image pickup apparatus according to an embodiment of the present application. As shown in fig. 14, in this case, the lens assembly 3 may include a first lens group 3a and a second lens group 3b, each of the first lens group 3a and the second lens group 3b includes at least one lens 31, the first lens group 3a is disposed outside the light incident side 21 of the reflector 2, and the second lens group 3b is disposed between the light emergent side 23 of the reflector 2 and the image sensor 1.

Specifically, after the lens assembly 3 is divided into different lens groups, one of the lens groups, for example, the second lens group 3b, may be disposed between the light-emitting side of the reflector 2 and the light-sensing surface of the image sensor 1, and the other lens groups, for example, the first lens group 3a, may be disposed outside the light-emitting side 21 of the reflector 2. The reflector 2 itself can rotate relative to the body 10, and accordingly, the first lens group 3a can rotate along with the rotation of the reflector 2, and can also be fixedly arranged relative to the body 10. When the first lens group 3a is fixed relative to the body 10 of the terminal device, the reflector 2 is only rotated to a predetermined position, for example, the front position of the body 10, and then is opposite to the first lens group 3a, and the external light sequentially passes through the first lens group 3a, the reflector 2 and the second lens group 3b and irradiates the image sensor 1. When the reflector 2 is located at another position, for example, the back position of the body 10, the external light only irradiates the image sensor 1 through the reflector 2 and the second lens group 3 b. Therefore, when the camera device 20 shoots the scenery and images of the body 10 in different directions, different shooting effects can be correspondingly achieved through different lens combinations. For example, the terminal device may capture a front image with a wide-angle lens and a rear image with a telephoto lens. Or other photographic effects known to those skilled in the art may be achieved by different combinations of lenses.

When the first lens group 3a rotates along with the rotation of the reflector 2, no matter which direction of the scenery is shot, the lenses 31 in the lens assembly 3 all keep the same arrangement and state, at the moment, the lens assembly 3 can be divided into a plurality of lens groups on different sides of the reflector 2, so that the lenses between different lens groups keep a preset distance, and the phenomenon that the distance between the lenses 31 in the lens assembly 3 is too short to affect imaging is avoided.

In order to move the different lenses 31 in the lens assembly 3 back and forth along the optical axis, optionally, the image capturing device 20 may further include a driving motor 5, and the driving motor 5 is configured to drive at least a portion of the lenses 31 in the lens assembly 3 to move, so as to perform a focusing operation or a focusing operation on the lens assembly 3.

Specifically, in order to avoid the driving motor 5 from affecting the normal imaging of the image pickup device 20, the driving motor 5 may be located outside the edge of the lens 31, as shown in fig. 2 or 12. The driving Motor 5 may be a Voice Coil Motor (VCM), a piezoelectric actuator Motor, or the like, and the lens 31 in the lens assembly 3 is driven to move by the movement of the driving Motor 5 itself, so as to change the relative distance between the lenses 31, and accordingly, the focal length of the image capturing device 20 is changed accordingly. The drive motor 5 may also be in the form of other conventional motors known to those skilled in the art, and is not limited thereto.

Optionally, the image capturing apparatus 20 may further include an Optical Image Stabilization (OIS) component, and the Optical image stabilization component may be disposed between the body 10 of the terminal device and the lens component 3. When the lens assembly 3 shakes along with the movement of the terminal device, the optical anti-shake assembly can generate corresponding reverse displacement compensation, so that the shake generated by the lens assembly 3 is reduced or even eliminated, and the imaging quality of the camera device 20 is improved.

In order to arrange the driving motor 5, the lens assembly 3, etc. in the image capturing device 20 on the body 10 and to have a certain position between the lens assembly 3, etc. and the image sensor 1, the body 10 may further include a fixing structure 7, a supporting structure 8 for connecting between the fixing structure 7 and the image sensor 1, etc. The image sensor 1 may be disposed on a circuit board 9, and the circuit board 9 is mounted on the supporting structure 8. The Circuit Board 9 may be a Printed Circuit Board (PCB), among others. In addition, the support structure 8 may also be used to support and fix optical devices such as infrared filters.

Both the fixed structure 7 and the supporting structure 8 may be supporting and mounting structures known to those skilled in the art, and will not be described herein.

Further, when the mirror 2 of the image pickup device 20 is turned to different directions for taking images located at different orientations of the terminal apparatus, the terminal apparatus needs or at this time the shooting direction of the image pickup device 20 to perform the corresponding operation.

In order for the terminal device to sense the orientation of the mirror 2 and perform the corresponding operation. As an optional mode, the terminal device further includes a position sensor and a processing unit, the position sensor is configured to detect a direction to which the reflector 2 rotates, and the processing unit is configured to determine an operating state of the image capturing device 20 according to the direction to which the reflector 2 rotates, where the operating state includes at least one of a front camera state and a rear camera state.

In particular, the position sensor may be of many different types and operation, for example, the position sensor may be of a contact or non-contact sensing type. When the position sensor is a contact sensor, the position sensor may be a microswitch or the like, and when the reflector 2 turns to a specific direction, the microswitch is touched by the reflector 2 or a rotating shaft or the like connected to the reflector 2, the microswitch can turn on or off a circuit, so as to send an indication signal, and the processing unit can determine that the reflector 2 has rotated to a preset direction according to the indication signal, and further determine the working state of the camera device 20. Alternatively, the position sensor may be other physical touch switches known to those skilled in the art.

When the position sensor is a non-contact sensor, the position sensor may sense the direction of the reflecting mirror 2 by infrared or electromagnetic means. For example, the position sensor may include a hall device, which may be located on the body 10 of the terminal device, and a magnetic element, such as a magnet, which may be provided on the reflecting mirror 2. Wherein the hall device may be located at the front surface of the body 10 or at the back surface of the body 10. When the mirror 2 is rotated to face the front surface of the body 10, the magnet approaches the hall device; and when the mirror 2 is rotated to the rear surface of the body 10, the magnet is away from the hall device. Correspondingly, the strength of the signal generated by the hall device changes correspondingly with the distance between the magnet and the hall device, so that the processing unit can judge whether the camera device 20 faces the front side of the terminal equipment or the rear side of the terminal equipment, and accordingly, the working state of the camera device 20 is correspondingly determined to be the front camera state or the rear camera state.

When the processing unit in the terminal device determines that the operating state of the camera device 20 is one of the front camera state and the rear camera state, the switching can be performed through a program or software built in the terminal device, so that the camera device 20 can be used as a front camera or a rear camera.

The processing unit may be a separate circuit component, or may be integrated with other processing and control circuits in the terminal device, for example, in the processor 180 of the terminal device.

The main body 10 of the terminal device may include other components and parts in addition to the camera 20, which will be described in detail below.

Taking the terminal device 100 as a mobile phone as an example, fig. 15 is a block diagram of an internal part structure when the terminal device in fig. 1 is a mobile phone. As shown in fig. 15, the terminal device 100 may include, in addition to the processor 180, a Radio Frequency (RF) circuit 110, a memory 120, other input devices 130, a screen 140, a sensor 150, an audio circuit 160, an I/O subsystem 170, a power supply 190, and the like. Those skilled in the art will appreciate that the handset configuration shown in fig. 15 is not intended to be limiting and may include more or fewer components than those shown, or may combine certain components, or split certain components, or arranged in different components. Those skilled in the art will appreciate that the screen 140 belongs to a User Interface (UI) and that the terminal device 100 may include fewer than or the illustrated User interfaces.

The other respective constituent components of the terminal device 100 will be specifically described below with reference to fig. 15:

the RF circuit 110 may be used for receiving and transmitting signals during information transmission and reception or during a call, and in particular, receives downlink information of a base station and then processes the received downlink information to the processor 180; in addition, the data for designing uplink is transmitted to the base station. Typically, the RF circuitry includes, but is not limited to, an antenna, at least one Amplifier, a transceiver, a coupler, a Low Noise Amplifier (LNA), a duplexer, and the like. In addition, the RF circuitry 110 may also communicate with networks and other devices via wireless communications. The wireless communication may use any communication standard or protocol, including but not limited to Global System for Mobile communication (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), email, Short Messaging Service (SMS), and the like.

The memory 120 may be used to store software programs and modules, and the processor 180 executes various functional applications and data processing of the terminal device 100 by operating the software programs and modules stored in the memory 120. The memory 120 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, an application program required for at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the terminal device 100, and the like. Further, the memory 120 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

Other input devices 130 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of terminal device 100. In particular, other input devices 130 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, a light mouse (a light mouse is a touch-sensitive surface that does not display visual output, or is an extension of a touch-sensitive surface formed by a touch screen), and the like. The other input devices 130 are connected to other input device controllers 171 of the I/O subsystem 170 and are in signal communication with the processor 180 under the control of the other input device controllers 171.

The screen 140 may be used to display information input by or provided to the user and various menus of the terminal device 100, and may also accept user input. The specific screen 140 may include a display panel 141 and a touch panel 142. The Display panel 141 may be a Liquid Crystal Display (LCD) or an Organic Light-Emitting diode (OLED)

Diode, organic light emitting Diode), or the like. The touch panel 142, also referred to as a touch screen, a touch sensitive screen, etc., may collect contact or non-contact operations (e.g., operations performed by a user on or near the touch panel 142 using any suitable object or accessory such as a finger or a stylus, and may also include body sensing operations; including single-point control operations, multi-point control operations, etc.) on or near the touch panel 142, and drive the corresponding connection device according to a preset program. Alternatively, the touch panel 142 may include two parts, i.e., a touch detection device and a touch controller. The touch detection device detects the touch direction and gesture of a user, detects signals brought by touch operation and transmits the signals to the touch controller; the touch controller receives the touch information from the touch detection device, converts the touch information into information that can be processed by the processor, sends the information to the processor 180, and receives and executes a command sent by the processor 180. In addition, the touch panel 142 may be implemented by various types such as a resistive type, a capacitive type, an infrared ray, a surface acoustic wave, and the like, and the touch panel 142 may also be implemented by any technology developed in the future. Further, the touch panel 142 may cover the display panel 141, a user may operate on the touch panel 142 according to the content displayed on the display panel 141 (the display content includes, but is not limited to, a soft keyboard, a virtual mouse, virtual keys, icons, etc.), the touch panel 142 detects a touch operation thereon or nearby, and transmits the touch operation to the processor 180 through the I/O subsystem 170 to determine the type of touch event to determine a user input, and then the processor 180 provides a corresponding visual output on the display panel 141 according to the user input through the I/O subsystem 170 according to the type of touch event. Although in fig. 15, the touch panel 142 and the display panel 141 are two separate components to implement the input and output functions of the terminal device 100, in some embodiments, the touch panel 142 and the display panel 141 may be integrated to implement the input and output functions of the terminal device 100.

The terminal device 100 may also include at least one sensor 150, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor that may adjust the brightness of the display panel 141 according to the brightness of ambient light, and a proximity sensor that may turn off the display panel 141 and/or the backlight when the terminal device 100 is moved to the ear. As one of the motion sensors, the accelerometer sensor can detect the magnitude of acceleration in each direction (generally, three axes), can detect the magnitude and direction of gravity when stationary, and can be used for applications of recognizing the posture of a mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer and tapping), and the like; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which can be configured in the terminal device 100, detailed descriptions thereof are omitted. Among them, those skilled in the art will appreciate that a position sensor for sensing the direction of the mirror 2 also belongs to the above-described sensor 150.

The audio circuitry 160, speaker 161, and microphone 162 may provide an audio interface between the user and the terminal device 100. The audio circuit 160 may transmit the converted signal of the received audio data to the speaker 161, and convert the signal into a sound signal for output by the speaker 161; on the other hand, the microphone 162 converts the collected sound signals into signals, which are received by the audio circuit 160 and converted into audio data, which are output to the RF circuit 108 for transmission to, for example, another cell phone, or to the memory 120 for further processing.

The I/O subsystem 170 controls input and output of external devices, which may include other devices, an input controller 171, a sensor controller 172, and a display controller 173. Optionally, one or more other input control device controllers 171 receive signals from and/or transmit signals to other input devices 130, and other input devices 130 may include physical buttons (push buttons, rocker buttons, etc.), dials, slide switches, joysticks, click wheels, a light mouse (a light mouse is a touch-sensitive surface that does not display visual output, or is an extension of a touch-sensitive surface formed by a touch screen). It is noted that other input control device controllers 171 may be connected to any one or more of the above-described devices.

When the mirror 2 needs to be rotated to change the shooting direction of the image pickup device 20, the direction of the light incident side 21 of the mirror 2 can be manually adjusted by a manual method, or the direction of the mirror 2 can be automatically adjusted. In one alternative, the direction of the light entrance side 21 of the mirror 2 may be adjusted manually. Specifically, the camera device 20 may be provided with a control element coupled with the reflector 2, and when a user applies a force to the control element with a hand, the control element drives the reflector 2 to rotate, so that the light incident side 21 of the reflector 2 points to a direction required by the user. Illustratively, the manipulating member may be a knob or a paddle, etc., which is connected to the reflector 2, and which is a manual manipulation structure commonly used by those skilled in the art.

Alternatively, the mirror 2 may be automatically adjusted in its orientation. At this time, in another alternative, the image pickup device 20 further includes a driving unit 4, and the driving unit 4 is used for driving the rotation of the mirror 2, as shown in fig. 15. Specifically, the driving unit 4 and the reflecting mirror 2 are directly or indirectly connected, so that the reflecting mirror 2 can be driven to rotate by self power. And electric connection has between the inside treater 180 of drive unit 4 and body 10 or the control unit, when terminal equipment need shoot the scenery that is located body 10 the place ahead or body 10 rear equidirectional scenery such as, terminal equipment's treater 180 or the control unit can send corresponding control command, let drive unit 4 drive speculum 2 rotate to equidirectional not, the rotation of speculum 2 can go on automatically like this, the user does not need manual position and the state that changes speculum 2, thereby the operation has been simplified, make to shoot more convenient.

The driving unit 4 may be a variety of different motors, such as a piezoelectric actuator motor or a driving motor commonly used by those skilled in the art, and the driving unit 4 and the mirror 2 may have a variety of different connection manners. For example, the driving unit 4 may be connected to a rotating shaft of the reflector 2, such as the first rotating shaft 24, and rotate the reflector 2 by controlling the rotation of the first rotating shaft 24; alternatively, the driving unit 4 may be directly or indirectly connected to another portion of the mirror 2 and move the portion of the mirror 2, so that the mirror 2 may be automatically rotated. In addition, the driving unit 4 may also be other driving structures and connection manners commonly used by those skilled in the art, and will not be described herein again.

When the reflector 2 rotates, in order to limit the rotation angle of the reflector 2, optionally, the image capturing device 20 further includes a limiting component (not shown in the figure) for limiting the rotation angle of the reflector 2 within a preset angle range.

Here, since the mirror 2 itself can have a large rotation range, when the image pickup device 20 is used, it is only necessary to turn the image pickup device 20 to the front or back of the terminal apparatus body 10. Therefore, the camera device 20 may further include a limiting component, and when the reflector 2 rotates to a preset angle, the limiting component blocks the rotation trend of the reflector 2, so as to limit the rotation angle of the reflector 2 within a preset angle range. However, the rotation angle of the mirror 2 is also different according to the rotation mode of the mirror 2. For example, in the aforementioned manner of rotating the mirror 2 in which the first rotation axis 24 is parallel to the focal plane of the image sensor 1, the mirror 2 rotates by an angle of about 90 °, and therefore the limiting component needs to limit the rotation angle of the mirror 2 within 90 °. And in the reflector 2 rotation mode of first pivot 24 and image sensor 1 mutually perpendicular, reflector 2 can be 360 rotations around first pivot 24, at this moment, can let spacing subassembly with the turned angle restriction of reflector 2 be 180 to make reflector 2 can rotate to the front of body 10 or the back of body 10, and need not to let reflector 2 accomplish the omnidirectional rotation of circumference.

In particular, the spacing assembly may have a variety of different configurations or types. For example, the limiting component may include a stop member which stops the rotation track of the reflector 2, or a stop member which is connected to the first rotation shaft 24 of the reflector 2 or the driving unit 4 and limits the rotation of the first rotation shaft 24 or the movement of the driving unit 4, or a limiting manner known to those skilled in the art, and is not limited herein.

In addition, when the mirror 2 is rotated by the driving unit 4, the processor 180 or other control unit may also send a limit instruction to the driving unit, so that the mirror 2 stops driving after rotating to the preset angle range, and at this time, the mirror 2 may stay at the position within the preset angle range.

Therefore, the terminal equipment can finish image shooting in different directions only through the same image sensor, and better shooting effect can be realized no matter which direction is shot.

In addition, the application also provides a shooting method of the terminal equipment. The photographing method in this embodiment may be applied to the terminal device in the above embodiment, so that the terminal device can make the image pickup device 20 photograph images in different directions around the terminal device by moving the optical element such as the mirror 2 in the image pickup device 20. Fig. 16 is a flowchart illustrating a shooting method of a terminal device according to an embodiment of the present application. As shown in fig. 16, the shooting method of the terminal device in the present embodiment is mainly applied to the terminal device in the foregoing embodiment. Specifically, this terminal equipment includes body 10 and camera device 20, and camera device 20 includes image sensor 1 and speculum 2, and the income light side of speculum 2 exposes the body 10 the outside, the play light side of speculum 2 is towards image sensor 1, and speculum 2 can rotate to the orientation the not equidirectional of body 10.

Specifically, in the imaging device 20, since the mirror 2 can rotate relative to the main body 10 of the terminal apparatus, it can be used to reflect incident light from different directions and reflect the incident light to the image sensor 1. Thus, the light entrance side 21 of the mirror 2 can be directed in different directions of the terminal device by rotation of the mirror 2. Correspondingly, when the terminal equipment shoots, the reflector 2 can be rotated according to the actual needs of the user, so that images facing the rear part (the back of the screen) of the terminal equipment are respectively shot, and the conventional shooting is finished; or shooting the image in front of the terminal equipment (on the front side of the screen) to realize self-shooting of the user.

Since the shooting direction of the image pickup device 20 needs to be determined according to the direction of the light incident side 21 of the mirror 2, the terminal device needs to detect the direction of the light incident side 21 of the mirror 2 in order to control shooting by the image pickup device 20. Wherein, during the detection, the detection can be carried out by a plurality of different means. Illustratively, a position sensor or the like may be employed to detect the actual orientation and direction of the mirror 2.

S102, determining the working state of the camera device according to the direction of the light incident side of the reflector, wherein the working state comprises a front camera state and a rear camera state.

Specifically, the operating state of the image capturing device 20 may include a front camera state and a rear camera state.

Optionally, the step may specifically be that when it is detected that the light incident surface of the reflector 2 faces the one surface of the body 10 with the screen, the working state of the camera device 20 is determined to be a front camera state; when the light incident surface of the detection reflector 2 faces the surface of the main body 10 away from the screen, the working state of the camera device 20 is determined to be the rear camera state.

Specifically, if the light incident side 21 of the reflector 2 faces the rear of the terminal device, that is, the back of the screen, the camera device 20 can shoot the scenery and images in front of the user, and the terminal device can determine that the camera device 20 is in the rear-facing camera state at this time, and switch the interface display mode and the operation mode of the terminal device to the mode corresponding to the rear-facing camera state. If the light incident side 21 of the reflector 2 faces the front of the terminal device, i.e. the front of the screen, then a user appears in the shooting screen of the camera device 20, and can mainly take a self-timer shooting, and the terminal device can confirm that the camera device 20 is in the front camera state at this time, and the interface display mode and the operation mode of the terminal device are also changed correspondingly.

The shooting direction and angle of the current camera device can be identified by detecting the direction of the incident light side of the reflector, and the corresponding switching camera device of the terminal equipment is in a front camera state or a rear camera state, so that the image shooting of the terminal equipment in different directions can be completed by the same image sensor in the camera device.
