Referring to fig. 1, fig. 1 shows a schematic diagram of a composition structure of an electronic device provided in the present application. In some electronic devices, the camera assembly 2 may be provided to capture images or record video by the camera assembly 2. As shown in fig. 1, when the image pickup device 2 is mounted below the display screen of the notebook computer, the image pickup device 2 is at a bottom view photographing angle because the user is at a higher position with respect to the image pickup device 2 when photographing the user. The image of the user thus captured may produce a relatively severe perspective distortion. Fig. 1 is only an example, and the camera assembly may be located at other positions of the computer, for example, above the display screen, and the position of the user relative to the camera assembly may be distorted.

Referring to fig. 2, fig. 2 shows a schematic diagram of perspective distortion provided by the present application. As shown in fig. 2, when the image pickup assembly 2 is at a photographing angle in a bottom view, in a direction along the central axis 211 of the optical lens, since distances from the upper and lower sides of the target object 5 to the optical lens 22 are not the same, that is, the upper and lower sides of the target object 5 have an object distance difference a with respect to the optical lens 22, a problem of perspective distortion occurs. And the larger the elevation angle of the bottom view photographing, the larger the object distance difference a between the upper and lower sides of the user and the optical lens 22, the more serious the distortion of the photographed image.

In view of this, the embodiment of the present application provides an electronic apparatus, which may be any electronic apparatus including an image capturing unit, and any electronic apparatus provided with an image capturing unit for capturing image data may be included within the scope of the embodiment of the present application. For example: notebook computers, tablet computers, desktop computers, all-in-one machines, and the like. For convenience of description, a notebook computer is taken as an example to describe the electronic device provided in the embodiment of the present application, but the electronic device is not limited to be only a notebook computer, and the embodiment of the present application does not limit the type of the electronic device.

Referring to fig. 3 and 4, fig. 3 shows a schematic diagram of a second component structure of the electronic device provided in the present application, and fig. 4 shows a schematic diagram of a first component structure of an image capturing assembly in the electronic device provided in the present application. The electronic device provided by the embodiment of the application comprises: a body 1 and a camera assembly 2; wherein the body 1 has a first region 11; the camera assembly 2 is movably arranged in the first area 11, the camera assembly 2 comprises an image sensor 21 and an optical lens 22, and the camera assembly 2 is movable relative to the body 1 such that in a radial direction E along the optical lens 22, a center axis 211 of the image sensor and a center axis 221 of the optical lens 22 have an offset B.

In this embodiment of the present application, the body 1 may be a part of a structural part in the electronic device, or may be another structural part in the electronic device except for the image capturing module 2. For example, in the case where the electronic device is a notebook computer, the body 1 may be a portion including a display unit provided for the notebook computer, or may be a portion including a keyboard provided for the notebook computer.

Illustratively, the first area 11 on the body 1 may be a part of the area of the body 1 near the edge portion, for example, the first area 11 may be a bezel portion on the B-side of the notebook computer. The first area 11 may be another area on the body 1, which is not limited in the embodiment of the present application.

In the embodiment of the present application, during the process of using the electronic device, an image of the user may be acquired, or an image of the target object 5 may be acquired. The camera assembly 2 may be disposed in the first region 11 and the camera assembly 2 may be movably disposed in the first region 11, such that the camera assembly 2 may move relative to the body 1. In this way, the position of the imaging module 2 on the main body 1 can be adjusted as necessary.

For example, the image pickup assembly 2 may be provided in a structure including the image sensor 21 and the optical lens 22. The optical lens 22 may be a lens assembly including a plurality of optical lenses, and the optical lens 22 is configured to refract and collect light reflected by the object to be photographed and then project the light onto the image sensor 21. The image sensor 21 is configured to convert an optical signal projected to a light sensing surface of the image sensor 21 through the optical lens 22 into an electrical signal, and then convert the obtained electrical signal into image data.

As another example, in the radial direction E of the optical lens 22, the optical lens 22 and the image sensor 21 may be provided in different axial structures, that is, the center axis 211 of the image sensor and the center axis 221 of the optical lens have an offset B. The central axis 211 of the image sensor and the central axis 221 of the optical lens are parallel or nearly parallel, and the central axis 211 of the image sensor and the central axis 221 of the optical lens are staggered by a certain distance along the radial direction E of the optical lens 22.

According to the electronic device provided by the embodiment of the application, since the camera shooting assembly 2 is movably arranged in the first area 11 of the body 1, when the camera shooting assembly 2 shoots the target object 5 and the plane where the target object 5 is located is not perpendicular to the central axis 221 of the optical lens, the position of the optical lens 22 relative to the target object 5 can be adjusted by adjusting the position of the camera shooting assembly 2 relative to the body 1, so that the central axis 221 of the optical lens and the plane where the target object 5 is located are perpendicular to each other or are close to each other. In this way, in the direction along the central axis 221 of the optical lens, the object distance difference a between different parts of the target object 5 and the optical lens 22 can be reduced, and then the perspective distortion generated after the light reflected by different parts of the target object 5 passes through the optical lens 22 can be reduced, and the distortion generated by the acquired image of the target object 5 can be reduced. Meanwhile, setting the center axis 211 of the image sensor and the center axis 221 of the optical lens to have the offset B in the radial direction E of the optical lens 22 allows the light reflected by the target object 5 having a large offset distance from the center axis 221 of the optical lens to pass through the optical lens 22 and then to be transmitted to the image sensor 21 entirely, so that the image data including the complete target object 5 can be acquired by the image sensor 21. Therefore, the electronic equipment provided by the embodiment of the application can reduce distortion generated by the acquired image.

In some embodiments, referring to fig. 5, fig. 5 shows a second schematic diagram of the composition structure of the camera assembly in the electronic device provided in the present application. The electronic device provided by the embodiment of the application further comprises a driving component 3 arranged in the body 1, wherein the driving component 3 is in transmission connection with the image pickup component 2 and is used for driving the image sensor 21 and/or the optical lens 22 to move so as to have an offset B.

In the embodiment of the present application, in order to have the required offset B between the image sensor 21 and the optical lens 22, it is necessary to enable relative movement between the image sensor 21 and the optical lens 22 in the radial direction E of the optical lens 22. The driving assembly 3 may be provided in the electronic device, and the driving assembly 3 is in driving connection with the image capturing assembly 2 to drive the image sensor 21 and the optical lens 22 to move, or to drive the image sensor 21 or the optical lens 22 to move, through the driving assembly 3.

The driving assembly 3 may be provided in a structure comprising a driving member and a transmission member, the driving member being fixedly mounted in the body 1, the transmission member being connected to an output shaft of the driving member, and the transmission member being drivingly connected to the image sensor 21 and/or the optical lens 22, for example. In this way, the driving member may be driven to move by the driving member, so as to drive the image sensor 21 and/or the optical lens 22 to move.

In the above embodiment, since the driving assembly 3 is disposed in the body 1 and the driving assembly 3 is in driving connection with the image pickup assembly 2, the image sensor 21 and/or the optical lens 22 can be driven to move by the driving assembly 3, so that the movement between the image sensor 21 and the optical lens 22 can be generated such that the image sensor 21 and the optical lens 22 have a desired offset B in the radial direction E of the optical lens 22.

In some embodiments, as shown in fig. 5, the image sensor 21 may be slidably disposed in the first region 11 of the body 1, and the driving assembly 3 is drivingly connected to the image sensor 21, and the driving assembly 3 is configured to drive the image sensor 21 to move relative to the optical lens 22 in a radial direction E along the optical lens 22.

In this embodiment, the optical lens 22 may be fixedly mounted in the first region 11 of the body 1 with respect to the image sensor 21, and the image sensor 21 may be slidably disposed in the first region 11 of the body 1.

For example, in order to facilitate the installation of the image sensor 21 and the optical lens 22, an image pickup holder 41 may be provided, the image pickup holder 41 is installed in the first area 11, the optical lens 22 is fixed on the image pickup holder 41, and the image sensor 21 is slidably provided on the image pickup holder 41 through an adapted guide rail and a slide groove. And, the central axis 211 of the image sensor and the central axis 221 of the optical lens are parallel or nearly parallel. For example, a guide rail may be provided on the imaging holder 41, and a chute may be provided on the image sensor 21; alternatively, a chute may be provided in the imaging holder 41, and a guide rail may be provided in the image sensor 21. Wherein, the extending direction of the guide rail is consistent with the radial direction E of the optical lens 22, so that the image sensor 21 can move along the radial direction E of the optical lens 22.

As another example, the driving member in the driving assembly 3 may be fixed to the image pickup bracket 41, and for example, a driving member such as a servo motor may be used as the driving member. The transmission member in the driving assembly 3 may adopt a matched gear and a rack, the gear may be fixed on the output shaft of the servo motor, and the rack may be fixed on the image sensor 21. In this way, the gear can be driven to rotate by the servo motor to drive the rack to move, so that the image sensor 21 can be driven to move.

In the above embodiment, since the image sensor 21 is slidably disposed in the first region 11 of the body 1 and the driving assembly 3 is drivingly connected to the image sensor 21, the image sensor 21 can be driven by the driving assembly 3 to move in the radial direction E of the optical lens 22, so that the image sensor 21 and the optical lens 22 can have a desired offset B therebetween.

In some embodiments, as shown in fig. 5, the optical lens 22 may be slidably disposed in the first region 11, and the driving assembly 3 is drivingly connected to the optical lens 22, where the driving assembly 3 is configured to drive the optical lens 22 to move relative to the image sensor 21 in a radial direction E of the optical lens 22.

In this embodiment, the image sensor 21 may be fixedly mounted in the first region 11 of the body 1 with respect to the optical lens 22, and the optical lens 22 may be slidably disposed in the first region 11 of the body 1.

For example, the image sensor 21 may be fixed to the image pickup holder 41, and the optical lens 22 may be slidably disposed on the image pickup holder 41 through an adapted guide rail and a slide groove. And, the central axis 211 of the image sensor and the central axis 221 of the optical lens are parallel or nearly parallel. For example, a guide rail may be provided on the imaging holder 41, and a slide groove may be provided on a lens barrel for mounting the optical lens 22; alternatively, a slide groove may be provided in the imaging holder 41, and a guide rail may be provided in the lens barrel. Wherein, the extending direction of the guide rail is consistent with the radial direction E of the optical lens 22, so that the optical lens 22 can move along the radial direction E of the optical lens 22.

As another example, the driving member in the driving assembly 3 may be fixed to the image pickup bracket 41, and for example, a driving member such as a servo motor may be used as the driving member. The transmission member in the driving assembly 3 may adopt a matched gear and rack, and the gear may be fixed on the output shaft of the servo motor, and the rack may be fixed on the lens barrel of the optical lens 22. In this way, the gear can be driven to rotate by the servo motor to drive the rack to move, so that the optical lens 22 can be driven to move.

In the above embodiment, since the optical lens 22 is slidably disposed in the first area 11 of the body 1 and the driving assembly 3 is in driving connection with the optical lens 22, the optical lens 22 can be driven by the driving assembly 3 to move along the radial direction E of the optical lens 22, so that the image sensor 21 and the optical lens 22 can have a required offset B.

In this embodiment, the image sensor 21 and the optical lens 22 may also be slidably disposed in the first area 11 of the body 1 along the radial direction E of the optical lens 22 at the same time, and the driving assembly 3 is in driving connection with the image sensor 21 and the optical lens 22 at the same time. For example, racks may be provided on both the image sensor 21 and the optical lens 22, and a gear mounted on an output shaft of the servo motor may be engaged with both racks at the same time. In this way, during the rotation of the gear, the two racks can be driven to move simultaneously in opposite directions, so that the image sensor 21 and the optical lens 22 can be moved simultaneously in opposite directions along the radial direction E of the optical lens 22, so as to change the offset B between the image sensor 21 and the optical lens 22.

In some embodiments, the electronic device provided in the embodiments of the present application further includes a pose sensor assembly electrically coupled to the driving assembly 3, the pose sensor assembly being configured to detect a pose state of the target object 5, the pose sensor assembly controlling the driving assembly 3 to drive the image sensor 21 and/or the optical lens 22 to move so as to adjust the offset B.

In this embodiment, in order to improve the usability of the electronic device, a pose sensor may be disposed in the electronic device, so as to detect the pose state of at least a part of the target object 5 or an area of the target object 5 located in the shooting area 23 of the imaging assembly 2 by using the pose sensor, and control the driving assembly 3 according to the pose state of the target object 5, so that the driving assembly 3 drives the image sensor 21 and/or the optical lens 22 to move.

Illustratively, the pose sensor assembly may employ an infrared sensor or the like, and the pose sensor assembly may detect the position of the target object 5 relative to the camera assembly 2. In this way, it can be determined whether the target object 5 is within the range of the photographing region 23 of the image pickup device 2. For example, in the case where it is detected that the target object 5 moves beyond the range of the photographing region 23 of the photographing assembly 2, a control signal may be transmitted to the driving assembly 3 through the pose-sensing assembly to drive the image sensor 21 and/or the optical lens 22 to move such that the offset B between the image sensor 21 and the optical lens 22 is adapted to the position where the target object 5 is located, so that image data including the target portion 51 of the target object 5 may be acquired.

In the above embodiment, since the pose sensor assembly is disposed in the electronic device and is electrically connected to the driving assembly 3, the driving assembly 3 can be controlled to drive the image sensor 21 and/or the optical lens 22 to move according to the pose state of the target object 5 detected by the pose sensor assembly relative to the image pickup assembly 2, so that the offset B between the image sensor 21 and the optical lens 22 can be adjusted, that is, the photographing region 23 of the image pickup assembly 2 can be adjusted, so that the target object 5 is located within the range of the photographing region 23 of the image pickup assembly 2, and further, the target object 5 moving to different positions relative to the image pickup assembly 2 can be photographed.

In some embodiments, as shown in fig. 5, the pose state of the target object 5 detected by the pose sensing assembly includes: an offset distance of the target portion 51 of the target object 5 in the radial direction E of the optical lens 22; the pose sensor assembly controls the driving assembly 3 to drive the image sensor 21 and/or the optical lens 22 to move to adjust the offset B, comprising: in the case where the actual offset distance D is greater than the minimum offset distance C, controlling the driving assembly 3 based on the actual offset distance D and the minimum offset distance C to drive the image sensor 21 and/or the optical lens 22 to move to adjust the offset amount B so that the target portion 51 is within the photographing region 23; the minimum offset distance C includes the minimum distance between the target portion 51 and the photographing region 23 in the case where the target portion 51 is located within the photographing region 23.

In this embodiment of the present application, the target object 5 may be located in front of the image capturing component 2 of the electronic device, where the position of the target object 5 relative to the electronic device may change, and the range of the capturing area 23 of the image capturing component 2 is limited. In the case where the target site 51 of the target object 5 is located within the range of the photographing region 23 of the photographing assembly 2 and moves within the photographing region 23, complete image data of the target site 51 can be acquired by the photographing assembly 2. In contrast, when at least a part of the target portion 51 moves out of the range of the photographing region 23, that is, when the target portion 51 of the target object 5 moves in the radial direction E of the optical lens 22, the actual offset distance D of the target portion 51 moving in the radial direction E of the optical lens 22 is greater than the minimum offset distance C between the target portion 51 and the photographing region 23, image data of a portion of the target portion 51 beyond the photographing region 23, that is, image data of the entire target portion 51 cannot be acquired.

Illustratively, as shown in fig. 4, the range of the photographing region 23 of the image pickup assembly 2 is related to the amount of offset B between the image sensor 21 and the optical lens 22. In the case where at least a part of the target portion 51 moves out of the range of the photographing region 23, the photographing region 23 of the image pickup assembly 2 can be adjusted by adjusting the offset amount B between the image sensor 21 and the optical lens 22, so that the adjusted photographing region 23 can cover the target portion 51 after the movement again.

As another example, as shown in fig. 5, in the process of moving the target object 5, in the case where the moving distance of the target object 5 relative to the photographing region 23 is smaller than the minimum offset distance C, the target object 5 is always within the photographing region 23, and then the complete image data of the target portion 51 can be acquired. At this time, the offset B between the image sensor 21 and the optical lens 22 may not be adjusted. In the case where the target portion 51 is located within the photographing region 23 in the radial direction E of the optical lens 22, the minimum offset distance C may be the minimum distance from the edge of the target portion 51 to the boundary of the photographing region 23.

In yet another example, in the case where the movement distance of the target object 5 with respect to the photographing region 23 is greater than the minimum offset distance C, at least a portion of the target object 5 is outside the photographing region 23, the image capturing assembly 2 cannot acquire an image of the portion of the target site 51 that is outside the photographing region 23 any more. At this time, the offset amount B between the image sensor 21 and the optical lens 22 may be adjusted according to the actual offset distance D and the minimum offset distance C of the target object 5. For example, the offset B may be adjusted according to the difference between the actual offset D and the minimum offset C; that is, by driving the driving assembly 3, the image sensor 21 and/or the optical lens 22 are driven to move to change the offset B, so that the photographing region 23 of the image capturing assembly 2 is changed, such that the photographing region 23 can cover at least the target portion 51, and thus complete image data of the target portion 51 after moving relative to the image capturing assembly 2 can be acquired. The larger the difference between the actual offset distance D and the minimum offset distance C, the larger the offset amount B. However, in order to satisfy the requirements for the sharpness of the acquired image, the offset B needs to be limited to a certain range.

In the above embodiment, since the offset B is adjusted according to the actual offset D and the minimum offset C of the target portion 51 of the target object 5 in the radial direction E of the optical lens 22, the photographing region 23 of the image capturing assembly 2 can be changed, so that the photographing region 23 can always cover the space where the target portion 51 is located, and further, after the target object 5 moves relative to the image capturing assembly 2, the image data including the complete target portion 51 can be acquired.

In some embodiments, as shown in fig. 5, the electronic device provided in this embodiment of the present application further includes an angle adjustment assembly 4 movably disposed on the body 1, and the camera assembly 2 is disposed on the angle adjustment assembly 4, and an included angle between the central axis 221 of the optical lens and the body 1 can be adjusted by the angle adjustment assembly 4, so as to adjust a shooting angle between the camera assembly 2 and the target object 5.

In this embodiment, in the process of using the electronic device, according to the usage habits of different users, the included angles between the body 1 of the electronic device and the target object 5 to be photographed may be different, that is, the included angle between the central axis 221 of the optical lens in the image capturing component 2 and the target object 5 is different, and then the image capturing component 2 may be in a state of upward shooting or downward shooting relative to the target object 5, so that the object distance difference a exists between different parts of the target portion 51 and the optical lens 22, and perspective distortion may be generated on the obtained image of the target portion 51. The angle adjusting component 4 can be arranged on the body 1 of the electronic device, so that the camera shooting component 2 is driven to move through the angle adjusting component 4, the included angle between the central axis 221 of the optical lens and the body 1 is changed, and the included angle between the central axis 221 of the optical lens and the target object 5 can be changed, so that the shooting angle between the camera shooting component 2 and the target object 5 can be adjusted.

By way of example, if the target object 5 is generally vertical, the central axis 221 of the optical lens may be adjusted to be horizontal or nearly horizontal. This can reduce the object distance difference a between different portions of the target portion 51 and the optical lens 22.

As another example, the angle adjustment assembly 4 may be provided in a structure including the camera support 41, the driving member 42, and the transmission member. The camera bracket 41 may be rotatably disposed on the body 1, and a rotation axis of the camera bracket 41 is perpendicular to the central axis 221 of the optical lens. The driving member 42 is fixed to the body 1, and the transmission member is mounted on an output shaft of the driving member 42 and is in transmission connection with the image pickup bracket 41. For example, the driving member 42 may collect a servo motor, etc., and the driving member may adopt a driving gear and a driven gear which are engaged with each other, and fix the driving gear on an output shaft of the servo motor, and fix the driven gear on a rotation shaft of the image pickup bracket 41. The driven gear can be driven by the servo motor to rotate so as to drive the camera support 41 to rotate, so that the camera assembly 2 can rotate along the rotation direction F relative to the body 1.

In the above embodiment, since the angle adjusting component 4 is disposed in the body 1 of the electronic device and the image capturing component 2 is disposed on the angle adjusting component 4, the angle between the optical lens 22 located on the image capturing bracket 41 and the body 1 can be adjusted by driving the image capturing component 2 to move relative to the body 1 by the angle adjusting component 4, so that the capturing angle between the image capturing component 2 and the target object 5 can be adjusted to be a right angle or a near right angle, and then the object distance difference a between different portions of the target portion 51 of the target object 5 and the optical lens 22 can be reduced, and the perspective distortion generated by the obtained image of the target portion 51 can be reduced, so as to improve the quality of the obtained image.

In some embodiments, the angle adjustment assembly 4 in the electronic device provided in the embodiments of the present application is further configured to obtain a vertical included angle between the body 1 and a vertical direction, and adjust the included angle between the angle adjustment assembly 4 and the body 1 according to the vertical included angle, so as to adjust the included angle between the central axis 221 of the optical lens and the body 1.

In this embodiment of the application, in order to adjust the shooting angle between the camera module 2 and the target object 5 in real time and rapidly, the angle adjusting module 4 may be further configured to obtain a vertical included angle between the body 1 and the vertical direction, so as to adjust the included angle between the angle adjusting module 4 and the body 1 according to the vertical included angle.

For example, an inclination sensor may be disposed in the angle adjustment assembly 4, so that a vertical angle between the angle adjustment assembly 4 and a vertical direction is measured by the inclination sensor, that is, a vertical angle between the body 1 driving the angle adjustment assembly 4 to move together and the vertical direction may be measured, and an angle between the central axis 221 of the optical lens and the vertical direction may be obtained.

As another example, in the case where the vertical angle is zero degrees, or near zero degrees, indicating that the photographing angle between the image pickup assembly 2 and the target object 5 is a right angle or near a right angle, there is no need to adjust the photographing angle of the image pickup assembly 2. Under the condition that the included angle between the camera shooting assembly 2 and the vertical direction exceeds the preset angle, the angle adjusting assembly 4 can be controlled to execute an adjusting action according to the vertical included angle so as to drive the camera shooting assembly 2 to move, so that the shooting angle of the camera shooting assembly 2 meets shooting requirements, namely, the shooting angle of the camera shooting assembly 2 is close to a right angle.

In the above embodiment, since the angle adjusting component 4 can also obtain the vertical angle between the body 1 and the vertical direction, the camera component 2 can be driven to move relative to the body 1 by the angle adjusting component 4 to adjust the angle between the central axis 221 of the optical lens and the body 1, so as to adjust the angle between the central axis 221 of the optical lens and the target object 5, and further adjust the shooting angle between the camera component 2 and the target object 5 according to different inclination angles of the body 1 relative to the target object 5, so that the shooting angle can be kept at a near right angle.

In some embodiments, the angle between the central axis 221 of the optical lens and the body 1 may be 0 to 45 °.

In this embodiment, when the target object 5 is at different positions relative to the image capturing component 2 and the capturing area 23 cannot cover the target portion 51 by adjusting the offset B, the included angle between the central axis 221 of the optical lens and the body 1, that is, the capturing angle of the image capturing component 2 to the target object 5, may be adjusted, so that the image capturing component 2 is in a state of tilting or pitching the target object 5. In this way, although the acquired image of the target portion 51 has perspective distortion, complete image data of the target portion 51 can be acquired.

For example, the angle range of rotation of the angle adjustment assembly 4 relative to the body 1 may be set to 0 to 45 °, so that the angle between the central axis 221 of the optical lens and the body 1 may be changed in the range of 0 to 45 ° during the rotation of the imaging assembly 2 relative to the body 1 by the angle adjustment assembly 4.

In the above embodiment, since the included angle between the central axis 221 of the optical lens and the body 1 is set to be variable in the range of 0 to 45 °, on one hand, the angle adjusting component 4 may drive the camera component 2 to move so as to change the shooting angle of the camera component 2, so that the range of the shooting area 23 of the camera component 2 may be increased; on the other hand, the movement of the camera shooting assembly 2 relative to the body 1 can be within a certain range, so that the occupied space of the camera shooting assembly 2 in the body 1 can be reduced, the miniaturization of the body 1 is facilitated, and the miniaturization of electronic equipment is also facilitated.

In some embodiments, as shown in fig. 4, in the electronic device provided in the embodiments of the present application, in the radial direction E of the optical lens 22, the range of the offset B is smaller than or equal to the radius of the imaging area of the image sensor 21.

In the present embodiment, the photographing region 23 of the image pickup device 2 can be changed by adjusting the offset amount B between the image sensor 21 and the optical lens 22. However, as is known from the principle of lens imaging, the light transmitted to the image sensor 21 through the optical lens 22 forms an image having a higher sharpness in the central region than in the peripheral region on the image sensor 21. In contrast, in the case where the offset B is larger, image data of a larger portion of the target portion 51 is formed in the peripheral region of the imaging region on the image sensor 21, so that the sharpness of the acquired image of the target portion 51 is reduced.

For example, the offset B between the image sensor 21 and the optical lens 22 may be set to be equal to or smaller than the radius of the imaging area of the image sensor 21. In this way, in the case of adjusting the photographing region 23 of the photographing assembly 2 by changing the offset amount B, it is also possible to make the obtained image have a certain sharpness.
