Detailed Description

The electronic equipment provided by the embodiment of the application is suitable for an auxiliary finger reading application scene. By adopting the electronic equipment provided by the embodiment of the application, the user only needs to vertically place the electronic equipment in front of the finger-reading book, so that the electronic equipment can shoot the finger-reading operation of the user on the finger-reading book, and the finger-reading of the user is further assisted.

A conventional electronic device for assisting finger reading is shown in fig. 1, and the electronic device can be erected on a desktop through a support of a support plate, and a reflector is arranged above a camera of the device, and the reflector is arranged to enable light from the desktop to enter the camera. When the electronic equipment is vertically placed in front of a book, the book image enters the camera through reflection of the reflector, so that shooting and imaging of the book by the camera are realized. At the moment, when the user reads the book, the camera of the electronic equipment shoots and identifies the finger reading action of the user, determines the content pointed by the user, and simulates reading of the content pointed by the user, so that the aim of assisting finger reading is fulfilled.

The conventional auxiliary finger-reading electronic device needs to shoot and image a book flatly placed on a desktop in an upright state without leaving the reflector. The mirror can be designed to be integrated with the electronic device or as a small part to be attracted by a magnet. The reflector is designed to be integrated with the electronic equipment, so that the electronic equipment has a convex shape and is not convenient to carry; the reflector is designed into a small part adsorbed by the magnet, so that the reflector is easy to lose and inconvenient to use.

Moreover, based on the fixed arrangement of the camera and the reflector, the width of the picture which can be shot by the camera is limited, and most books are opened and closed left and right. When a user opens a book and lays the book on a desk, the width of the book is large, the imaging range of the conventional auxiliary electronic equipment cannot completely cover the opened book, and if the user moves the position of the book slightly, the electronic equipment cannot shoot effective images, and the user has to adjust the position of the electronic equipment or the book in time in the pointing and reading process so as to ensure that the pointing and reading position of the user can be shot by the electronic equipment.

Therefore, the conventional electronic device for assisting finger reading is not neat in structure, inconvenient to use, limited in imaging width and difficult to ensure full-coverage shooting of books.

Compared with the conventional auxiliary finger reading electronic equipment, the electronic equipment provided by the embodiment of the application is tidier in structure, larger in imaging range and further convenient for a user to read.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

An embodiment of the present application provides an electronic device, as shown in fig. 2, the electronic device includes:

the device comprises a device body 1, at least two camera modules 2 arranged on the device body 1, and a processor 3 electrically connected with the at least two camera modules 2;

the orientations of the cameras of the at least two camera modules 2 are the same as the front orientation of the equipment body 1, and the cameras are inclined towards the bottom of the equipment body 1;

and the processor 3 is used for splicing the images acquired by the at least two camera modules 2 to obtain a spliced image.

Specifically, the electronic device may be any mobile electronic device having data processing capability, especially having image capturing and processing capability based on a camera module, such as a mobile phone, a tablet computer, a digital camera, a video camera, and a sound recorder. In the embodiment of the present application, the electronic device refers to a mobile intelligent electronic device with an auxiliary finger reading function, such as a smart phone, a tablet computer, a learning machine, and the like.

The device body 1 of the electronic device includes a main body case, and various functional components such as a processor, a battery, and a speaker, which are mounted in an internal space surrounded by the main body case. The installation of various functional components inside the main body housing can refer to the common installation manner of various functional components inside the electronic equipment, and is not described in detail herein.

In the embodiment of the present application, the apparatus body 1 is a flat plate structure, i.e., the front and back surfaces of the housing are both planar and parallel to each other.

The camera module 2 is configured to collect image data and send the collected image data to the processor 3 for processing.

The embodiment of the application sets up two at least camera modules 2 for above-mentioned electronic equipment, and two at least camera modules 2 distribute and install on equipment body 1 to the shooting direction that sets up each camera module 2 does not overlap completely. Through the setting of above-mentioned two at least camera modules 2, above-mentioned electronic equipment can realize the shooting to the equidirectional not, and its shooting range is wider.

As a preferred implementation manner, in the embodiment of the present application, the at least two camera modules 2 are installed at the same horizontal position of the device body 1, so that the shooting ranges of the camera modules 2 are transversely distributed, and the transverse shooting range of the electronic device can be expanded.

Wherein, two at least camera modules 2 are installed in same horizontal position of equipment body 1, mean that two at least camera modules 2 are installed along same horizontal direction dispersion on electronic equipment for each camera module 2 is the same apart from the height of electronic equipment bottom.

In fig. 2, two camera modules 2 are taken as an example to show the installation positions of at least two camera modules 2 of the electronic device on the device body 1 of the electronic device, and when the number of the camera modules 2 is larger, each camera module 2 can be installed on the same horizontal position of the device body 1 as shown in fig. 2.

The at least two camera modules 2 can be arranged in the equipment body 1 or on the outer surface of the equipment body 1, and can be arranged through a fixed structure or a detachable structure.

As a preferable arrangement, in the embodiment of the present application, the at least two camera modules 2 are installed in the electronic device, and the installation does not affect the original shape of the device body 1 of the electronic device, that is, the camera modules 2 are completely placed in the device body 1, and the main body housing of the device body 1 maintains the original shape.

It can be understood that, arbitrary mounting means all uses the normal shooting of guaranteeing camera module 2 and is in the same horizontal position of equipment body 1 as the prerequisite, moreover, should guarantee that the orientation of each camera module 2 follows following the setting:

the orientation of the cameras of the at least two camera modules 2 is the same as the orientation of the front face of the equipment body 1. The direction of the camera is the same as the direction of the front surface of the apparatus body 1, and is any direction in the range from minus 90 degrees to plus 90 degrees with reference to the normal of the plane where the front surface of the apparatus body 1 is located (the normal is outward perpendicular to the front surface of the apparatus body 1). The camera module 2 is arranged so that the electronic device has a front camera and can acquire images towards the front of the electronic device.

When the electronic device provided by the embodiment of the application is applied to an auxiliary finger reading scene, a user usually uses a front camera of the electronic device to collect the finger reading scene of the user on a book, and then the content pointed by the user is simulated to be read aloud. In the above scenario, the electronic device is generally placed upright with its front facing the user and the book that the user points to read, in order to capture the user-directed image.

According to the conventional arrangement scheme of the front camera of the electronic equipment, the imaging direction of the front camera of the electronic equipment is perpendicular to the front face of the electronic equipment, namely the optical axis of the camera is perpendicular to the front face plane of the electronic equipment. At the moment, the front camera of the electronic equipment forms images towards the front of the equipment, and the book on the desktop in front of the equipment is not in the imaging range of the book. In the above-mentioned auxiliary reading scenario, the user needs to manually adjust the upright electronic device to tilt toward the book to be read by the user, so that the front-facing camera thereof can capture the image read by the user.

The arrangement of the camera module 2 of the electronic device provided by the embodiment of the application is different from that of a conventional front camera of the electronic device. As shown in fig. 3, in the embodiment of the present invention, the camera module 2 is installed inside the main body 1 of the electronic device in an inclined manner, and the orientation of the camera is inclined toward the bottom of the main body 1.

The bottom of the main body 1 is an edge portion that is in contact with the table top and supports the electronic device to stand upright when the electronic device is placed upright for assisting finger reading.

Based on the above arrangement of the embodiment of the present application, when the electronic device is used for assisting reading and is placed upright, as shown in fig. 3, the camera module 2 of the electronic device collects images obliquely downward toward the front of the device, and images are not formed in a direction perpendicular to the front plane of the device and toward the front of the device, and at this time, the book located in front of the electronic device is within the imaging range of the camera module 2. Therefore, the user does not need to manually adjust the electronic equipment to incline towards the book direction, and only needs to place the electronic equipment in an upright state.

Further, because this application embodiment sets up two at least camera modules 2 for above-mentioned electronic equipment to two at least camera modules 2 are installed in the same horizontal position of equipment body 1, then each camera module 2 is installed along the dispersion of same water flat line on electronic equipment, and the horizontal region that each camera module 2 can shoot is different like this. Specifically, the shooting areas of the camera modules 2 are distributed in parallel in the horizontal direction.

Assuming that the electronic device proposed in the embodiment of the present application includes two camera modules 2, the shooting ranges of the two camera modules 2 are as shown in fig. 4.

Wherein 201 is the camera module on the right, 207 is the camera module on the left, 202 is the electronic equipment, that is, 201 and 207 two camera module groups are set up in the upper portion of electronic equipment 202 both ends about same horizontal position. When the electronic device is vertically placed on a desktop, the back surface of the electronic device is provided with a supporting plate, as shown in fig. 3, so that the back surface of the electronic device is placed at a certain angle with the desktop. In fig. 4, 203 and 206 refer to the right and left pages of the reading book, 204 is the image capturing area of the

right camera module

201, and 205 is the image capturing area of the left camera module 207, respectively. It is thus clear that the horizontal imaging range of two camera modules is different, through the horizontal orientation of adjusting each camera module, can make the horizontal imaging range of each camera module adjacent or have partial overlap.

Based on the setting of each camera module 2 and the imaging range characteristics of each camera module 2, this embodiment of the application still sets up a treater 3 for foretell electronic equipment, and this treater 3 and each camera module 2 electric connection. The processor 3 may be any type of processor having at least an image processing function. When each camera module 2 collects an image, the collected image is sent to the processor 3, and the processor 3 performs splicing processing on the image collected by each camera module 2 to obtain a spliced image.

For example, the processor 3 may be disposed inside the apparatus body 1, may be mounted on the surface of the apparatus body 1, or may be disposed separately from the apparatus body 1, for example, may be an independent processor connected to the at least two camera modules 2 in a wireless or wired manner.

In the present embodiment, the processor 3 is preferably provided inside the apparatus body 1. When the processor 3 is provided inside the device body 1, it may be integrated with a processor of an electronic device, and may be, for example, a CPU, a processing chip, or the like of the electronic device.

For example, as shown in fig. 4, the processor 3 splices the image obtained by shooting the image shooting area 204 by the right camera module 201 and the image obtained by shooting the image shooting area 205 by the left camera module 207 to obtain a spliced image, and the spliced image is equivalent to an image obtained by simultaneously shooting the

image shooting areas

204 and 205 in the figure, and is equivalent to that the electronic device can shoot and image the image shooting areas shown by 204 and 205 in the figure, and the shooting range of the electronic device is far greater than that of a single camera module, especially the transverse shooting range of the single camera module.

It can be understood that because each camera module 2 is different to the shooting angle that indicates to read books and shoot, perhaps because each camera module 2 is different at the mounting height on equipment body 1, all can make each camera module 2 shoot the difference such as size, visual angle and the scale of the image that obtains. At this time, when the processor 3 splices the images shot by each camera module 2, the images shot by each camera module 2 may be preprocessed first to make each image meet the image splicing requirement. For example, the images captured by the camera modules 2 are cut into images with the same size, or the viewing angles of the images captured by the camera modules 2 are adjusted to make the images captured by the camera modules 2 meet the stitching requirements, or the brightness, contrast, resolution, and the like of the images captured by the camera modules 2 are unified, so as to ensure that the display effects of the stitched images are uniform. When the technical scheme of the embodiment of the application is specifically implemented, other image splicing preprocessing schemes can be adopted to preprocess the images shot by the camera modules 2, so that the subsequent image splicing processing can be performed conveniently.

As an exemplary implementation manner, the processor 3 performs a stitching process on the images captured by the camera module 2, and may be implemented according to the following scheme:

as shown in fig. 4, when the two camera modules respectively shoot a left page image and a right page image of a finger-reading book, the processor 3 compares the left page image with the right page image, then determines similar or identical parts in the left page image and the right page image through the compared images, so that repeatedly shot picture areas L1 and R1 can be found out through the similar or similar images, then compares the images L1 and R1 of the same parts to select a shot part which is clear, cuts off the shot part which is not clear, so that an image a can be generated, and then splices the non-repeated image areas of the left page image and the right page image with the image a, namely, splices the whole shot image, namely, obtains a spliced image.

According to the above description of the embodiment of the present application, when more camera modules 2 are provided for the electronic device, the horizontal shooting range of the electronic device is further increased. Therefore, for example, as shown in fig. 4, when a reading book is transversely unfolded and laid on a desk, the electronic device according to the embodiment of the present application can shoot all pages of the book at the same time, and a user can ensure shooting and recognition of the reading action of the electronic device during page turning and reading.

As can be seen from the above description, the camera of the electronic device proposed in the present application is oriented in the same direction as the front face of the device body and is inclined toward the bottom of the device body. Based on the above setting, when this electronic equipment stands upright and places, its camera is towards its positive downward direction formation of image, when being used for this electronic equipment to indicate to read the scene, this electronic equipment can carry out image acquisition to the books of keeping flat in its dead ahead desktop automatically under the state of standing upright, need not user's manual adjustment electronic equipment imaging direction, can simplify supplementary finger and read the operation content, do benefit to and make the user focus on more pointing on and read.

Furthermore, the electronic device provided by the application can shoot in different directions and can splice the shot images. The multi-direction shooting and the image splicing processing can expand the imaging width of the electronic equipment. When a user horizontally unfolds and places a book in front of the front face of the electronic equipment for reading, the position of the electronic equipment does not need to be adjusted in the process of turning pages left and right of the user, so that any area on the unfolded book can be shot, and the user can further conveniently read the book by pointing.

As an optional implementation manner, referring to fig. 2, the electronic device further includes a display screen 4, the display screen 4 is installed on the front surface of the device body 1, and the at least two camera modules 2 are installed above the display screen 4 in a distributed manner or installed on two sides of the display screen 4 in a distributed manner.

When the at least two camera modules 2 are arranged above the display screen 4 in a distributed manner, the camera modules 2 are arranged above the display screen 4 in a distributed manner, so that the overlapping of the transverse shooting ranges of the camera modules 2 is smaller; when the aforesaid at least two camera modules 2 distribute and install in the both sides of display screen 4, each camera module 2 distributes and installs in the both sides upper portion of display screen 4 to when electronic equipment is upright, each camera module 2 can have the shooting field of vision that is big enough.

The display screen 4 can be any type of display screen, such as a liquid crystal display screen, a L CD display screen, and the like, as a preferred implementation, the embodiment of the present application adopts a L CD touch display screen as the display screen 4.

On the front of the above-mentioned equipment body 1, cover a complete screen cover plate, the size of this screen cover plate is the same with the front size of equipment body 1. Due to the covering of the screen cover plate, the front surface of the electronic equipment is of a smooth flat plate structure. Meanwhile, in order to meet requirements of light transmission and shielding of the screen, different parts of the screen cover plate can be designed to have different colors and light transmission, for example, a screen display area is made of transparent materials, and an area outside the screen display area can be made of non-transparent any color, so that effects of shielding an internal structure and being attractive are achieved.

Since the non-display screen area of the screen cover is designed to be opaque, but the camera module 2 is installed above or on both sides of the display screen 4 and inside the apparatus body 1, the light path of the camera module 2 is blocked.

For the convenience of camera module 2 formation of image, this application embodiment corresponds each camera module 2 position department on equipment body 1 and sets up the screen apron windowing respectively, just also corresponds each camera module 2 position department on the positive screen apron of equipment body and sets up a screen apron windowing, and the screen apron material of this screen apron windowing department is the transparent glass material, can make light see through the screen apron smoothly and get into camera module 2 like this.

The shape and size of the above-mentioned opening of the screen cover can be flexibly set, and are preferably set according to the size of the space capable of opening the window, the inclination angle of the camera module 2 relative to the screen cover, and the angle of view of the camera module 2.

Further, in order to increase the light transmittance of the screen cover plate window, and thus ensure the imaging effect of the camera module 2, in the embodiment of the present application, the inner surface of the glass in the screen cover plate window area is covered with a layer of antireflection film, so as to increase the light transmittance of the screen cover plate window.

It can be understood that, when camera module 2 inclines to install in the inside of equipment body 1, because camera module 2 is the tilt state, its required thickness space will be bigger certainly. However, the inner space thickness of the equipment body 1 is limited, and along with the electronic equipment is designed to be more and more light and thin, the inner thickness space of the equipment body 1 is smaller and smaller, the camera module 2 is required to be obliquely installed at the moment, a considerable imaging visual field is ensured at the same time, the structure and the size of the camera module 2 are required to be selected and designed, the camera module 2 is ensured to be obliquely arranged in the limited thickness space as much as possible, and therefore effective imaging of the front book of the electronic equipment is realized.

Based on the above-mentioned demand, this application embodiment carries out special design to camera module 2.

First, the embodiment of the present application excludes an AF type camera module, that is, an autofocus camera module, and the AF type camera module with a focus motor is relatively large in thickness, so that an FF type camera module, that is, a fixed focus camera module, is preferable.

Secondly, for the above-mentioned fixed focus camera module, this application embodiment still designs its size and mode of assembly according to the thickness of equipment body 1.

Specifically, in order to pursue extremely small size, this application embodiment preferably adopts a fixed focus camera module, and this fixed focus camera module comprises camera and base. The camera lens of traditional tight shot camera module has the screw thread, and under the supplementary of screw thread, the base is advanced in the camera rotation, and after adjusting the focus, use glue to fix the camera. In order to reduce the thickness of camera module, this application embodiment changes the mounting means of camera on the base, changes into fixing on the base through buckle structure, promptly, cancels the camera thread, directly calculates after the good focus, detains on the base. Because no screw thread exists, the overall thickness of the camera module can be reduced by about 2 millimeters.

It can be understood that, in the practical application of the technical solution of the embodiment of the present application, the above design idea of the embodiment of the present application can be referred to, and the size and the assembly manner of the camera module are flexibly designed according to the actual size of the device body 1, the manufacturing process and the design level of the camera module, and the like.

As an exemplary implementation manner, referring to fig. 5, in the embodiment of the present application, a camera bracket 5 is disposed inside an apparatus body 1 for installing a camera module 2.

The camera bracket 5 is mounted on the inner surface of the rear shell 11 of the device body 1, and the at least two camera modules 2 are obliquely mounted on the camera bracket 5.

Illustratively, the structure of the camera support 5 can be flexibly set according to the internal space of the device body 1, and the material thereof can also be flexibly selected. In the embodiment of the present application, the camera bracket 5 is made of plastic.

The installation of the camera module 2 on the camera bracket 5 can also be flexibly arranged. For example, the fixing device can be fixedly installed, and the fixing device can also be installed in a detachable installation mode such as a thread structure and a buckling structure.

In order to promote the formation of image effect of camera module 2, install a camera cover 6 respectively on every camera module 2 in this application embodiment, this camera cover 6 is non-transparent material, and its one end suit is on the camera of camera module 2, and the other end is the opening design. This camera cover 6's setting can prevent that the parasitic light from getting into the camera of camera module 2, can reduce the noise point that camera module 2 shot the image, makes it shoot the image more clear.

Furthermore, in order to further optimize the optical path of the camera module 2, the distance between the book and the electronic device is shortened when the camera module 2 shoots the image. In the embodiment of the present application, a wedge-shaped mirror 7 is respectively configured for each camera module 2. The wedge-shaped mirror 7 is made of a transparent material, such as transparent glass or transparent plastic.

As shown in fig. 5, the wedge mirror 7 may be attached to the opening end of the camera head cover 6, or the wedge mirror 7 may be attached to the inner surface of the opening of the screen cover. The wedge-shaped mirror 7 can be mounted by optical double-sided adhesive tape. When the wedge mirror 7 is attached to the opening end of the camera head cover 6 or the inner surface of the window of the screen cover, the upper thickness is smaller than the lower thickness.

As shown in fig. 6, after the wedge mirror 7 is installed in front of the camera module 2, the wedge mirror 7 intervenes in the optical path of the camera module 2. The light rays are refracted twice when passing through the wedge-shaped mirror 7, so that the light path of the camera module 2 is inclined downwards. As shown in fig. 6, the optical paths shown in 403 and 404 are the optical paths of the camera module 2 when the wedge mirror 7 is not added, and the optical paths shown in 405 and 406 are the optical paths of the camera module 2 after the wedge mirror 7 is added.

It can be seen by contrast that the setting of foretell wedge type mirror 7 can make the light path of camera module 2 further slope down to make its shooting region move to equipment body 1 openly, when this electronic equipment was used for the supplementary reading of indicating, the user can place the book of indicating reading in the position that is closer with electronic equipment, thereby convenience of customers and electronic equipment's interaction.

As an alternative implementation manner, each camera module 2 of the electronic device provided in the embodiment of the present application is respectively mounted on the device body 1 through a rotatable structure, and the rotatable structure can rotate in the horizontal direction.

Illustratively, the camera module 2 is mounted on the rotatable structure, and at the same time, the rotatable structure is mounted on the device body 1. And the rotating shaft of the rotatable structure is arranged in a vertical state, so that the rotatable structure can rotate along the horizontal direction. The camera module 2 is mounted on the rotatable structure, and maintains a state of being inclined downward as shown in fig. 3. It can be understood that the shooting range of the camera module 2 in the horizontal direction can be further expanded as the rotatable structure rotates in the horizontal direction.

In a preferred embodiment, the camera module 2 is mounted inside the apparatus body 1 through the rotatable structure. At this time, the rotatable structure may be fixedly installed on the inner surface of the rear case of the apparatus body 1, while the camera module 2 is obliquely installed on the rotatable structure.

Further, as shown in fig. 5, when the camera mount 5 is mounted on the inner surface of the rear case of the apparatus body 1, the rotatable structure described above may be mounted on the camera mount 5, thereby realizing the mounting of the rotatable structure on the inner surface of the rear case of the apparatus body 1.

As a preferred implementation, the rotatable structure described above is an electromagnetically controlled rotatable structure. The processor 3 is electrically connected to the rotatable structure for controlling the rotatable structure to rotate along the horizontal direction.

For example, the processor 3 may receive a rotating camera operation instruction triggered by a user, and when receiving the rotating camera operation instruction, the processor 3 controls the rotatable structure to rotate in the horizontal direction. Or, the processor 3 automatically determines the position of the instruction reading book according to the images sent by the camera modules 2, and then controls the rotatable structure to rotate along the horizontal direction, so that the camera modules 2 can shoot the instruction reading book more completely.

The specific composition of the above-mentioned electromagnetically-controlled rotatable structure is shown in fig. 7 and 8, and the rotatable structure mainly comprises a mounting bracket, a power supply circuit, and a camera base mounted on the mounting bracket.

The mounting bracket may be mounted on the apparatus body 1, for example, directly inside or on the surface of the apparatus body 1, or may be mounted on the inner surface of the rear case of the apparatus body 1 via the camera bracket 5. The mounting bracket is mainly used for bearing various components of the rotatable structure, and the specific structure and shape of the mounting bracket can be flexibly arranged according to the internal space of the equipment body 1 or the specific structure of the camera bracket 5.

The camera base is arranged on the mounting bracket through a rotating shaft and is used for bearing the camera module 2. This pivot is the pivot of vertical setting for it can be rotatory along the horizontal direction, and, based on the horizontal rotation of this pivot, can drive the camera base and rotate along the horizontal direction, also makes camera module 2 of installing on the camera base rotatory along the horizontal direction promptly.

The electromagnet is arranged on the back face of the camera base, the magnets are respectively arranged on the mounting supports on the two sides of the camera base, and the magnetic poles of the two magnets arranged on the mounting supports in the opposite planes are opposite, so that a magnetic field penetrating through the electromagnet can be generated, and when the electromagnet is electrified, the camera base can rotate under the action of the magnetic field, namely, the camera module 2 on the camera base rotates. The rotation angle of the camera module 2 can be controlled by controlling the size of the electrifying current of the electromagnet.

The power supply circuit is electrically connected with the electromagnet and used for supplying power to the electromagnet. Meanwhile, the power supply circuit is connected with a battery of the electronic equipment, and the battery of the electronic equipment is used as a power supply. The output current of the power supply circuit can be adjusted, so that the power supply circuit is also electrically connected with the processor 3, and the processor 3 can control the output current of the power supply circuit. That is, the processor 3 controls the rotation angle of the rotatable structure by controlling the magnitude of the current output by the power supply circuit of the rotatable structure.

For example, after receiving the current regulation instruction, the processor 3 controls the output current of the power supply circuit according to the current regulation instruction; or, after receiving the lens rotation instruction, the processor 3 judges the direction and angle of lens rotation according to the lens rotation instruction, and according to the lens rotation direction and angle, can determine whether the current of the electromagnet needs to be increased or decreased, and further control the output current of the power supply circuit; or, the processor 3 automatically determines the rotation direction and angle of the camera module 2 according to the image sent by the camera module 2, and further determines the current control strategy for the power supply circuit and controls the output current of the power supply circuit. The device body or hardware independent of the device body can be provided with corresponding touch buttons, so that a user can conveniently send a current adjusting instruction or a lens rotating instruction to the processor through the corresponding touch buttons. Or, the user can control the processor through voice, and the equipment body can collect voice signals so that the processor can identify the voice signals to obtain corresponding instructions.

For example, a variable resistor is provided in the power supply circuit, and a control device for adjusting the resistance value of the variable resistor, the variable resistor is connected to the output end of the power supply circuit, and when the resistance value of the variable resistor changes, the output current of the power supply circuit changes accordingly. When the processor 3 controls and adjusts the output current of the power supply circuit, a control instruction is sent to the variable resistor control device in the power supply circuit, so that the control device adjusts the resistance value of the variable resistor, and the adjustment of the output current of the power supply circuit is realized.

When the processor 3 controls the power supply circuit to input current to the electromagnet, the current of the electromagnet is increased from 0, the magnetic force of the electromagnet is increased along with the increase of the current, and the electromagnet can drive the camera module 2 to rotate under the action of the magnetic force in a magnetic field; in the above process, the larger the current output by the power supply circuit is, the larger the magnetic force of the electromagnet is, and the larger the angle of rotation of the camera module 2 is. When the processor 3 judges that the camera module 2 shoots a target picture by receiving the shot image sent by the camera module 2, the current value output by the control power supply circuit is not increased any more and becomes a constant value, at this time, the rotation angle of the camera module 2 is not changed any more, and the camera module 2 is in a static state.

It can be understood that the camera module 2 is installed inside the device body 1 through the above electromagnetic control rotatable structure, so that the processor 2 of the electronic device can flexibly control the shooting direction of the camera module 2. When the electronic equipment is vertically placed on a table surface, the shooting range of the electronic equipment can be flexibly changed through the control of the processor 3, so that the electronic equipment is more intelligent.

the device comprises a device body 101, a camera module 102 arranged on the device body 101 through a rotatable structure, and a processor 103 electrically connected with the camera module 102, wherein the rotatable structure can rotate along the horizontal direction;

the orientation of the camera module 102 is the same as the front orientation of the equipment body 101, and the camera is inclined towards the bottom of the equipment body 101;

the processor 103 is configured to perform stitching processing on images shot by the camera module 102 in the same shooting period to obtain a stitched image;

the images shot by the camera module 102 in the same shooting period include images shot by the camera module 102 in the same shooting period when the rotatable structure rotates to different positions.

Specifically, unlike the electronic device described in the above embodiment, the electronic device provided in the embodiment of the present application has only one camera module 102, and the camera module 102 is mounted on the device body 101 of the electronic device through a rotatable structure that can rotate in the horizontal direction.

As an exemplary implementation manner, referring to fig. 9, a display screen is disposed on a front surface of the apparatus body 101, and the camera module 102 is installed at a central position above the display screen. In specific implementation of the technical solution of the embodiment of the present application, the installation position of the camera module 102 on the device body 101 may be flexibly set, for example, the camera module 102 may also be installed at a vertex angle position of the front surface of the device body 101, or may be installed on any end surface of the device body 101. This camera module 102 can install in the inside or the surface of equipment body 101, when camera module 102 installs in the inside of equipment body 101, sets up logical unthreaded hole on the surface of equipment body 101 to camera module 102 shoots.

It is important to note that in the present embodiment, the camera module 102 is installed on the device body 101 through a rotatable structure capable of rotating horizontally. By the horizontal rotation function of the rotatable structure, the camera module 102 can rotate in the horizontal direction, that is, can shoot in different directions along the same horizontal plane, thereby expanding the horizontal shooting range.

Meanwhile, the embodiment of the present application sets that the orientation of the camera module 102 is the same as the orientation of the front surface of the apparatus body 101, and the camera is inclined toward the bottom of the apparatus body 101. By the inclined arrangement of the shooting direction of the camera module 102, when the electronic device is placed upright, the camera module 102 shoots downwards towards the front of the device body 101.

When the electronic device is applied to the auxiliary finger reading, a user vertically places the electronic device on a desktop, and places a finger-reading book in front of the electronic device, the camera module 102 of the electronic device can shoot the finger-reading book placed on the desktop in front of the electronic device.

In the embodiment of the present invention, a processor 103 is further provided for the electronic device, and the processor may be any type of processor at least having an image processing function, and may be disposed inside the device body 101, or may be installed on a surface of the device body 101, or may be disposed independently of the device body 101, for example, may be an independent processor connected to the at least two camera modules 102 in a wireless or wired manner.

In the embodiment of the present application, the processor 103 is preferably disposed inside the apparatus main body 101. When the processor 103 is provided inside the device main body 101, it may be integrated with a processor of an electronic device, and may be, for example, a CPU, a processing chip, or the like of the electronic device.

In the embodiment of the present invention, the camera module 102 sends the images captured in the same capturing period to the processor 103 during the image capturing process.

The same shooting period refers to a period of time from the start of shooting to the end of shooting by the camera module 102, and the camera module 102 can horizontally rotate at any time to shoot in different directions in the period of time. The shooting period can be flexibly set, for example, a fixed time period, and also can be the set shooting times of the camera module 102. For example, a set time period after the camera module 102 starts shooting may be set as one shooting cycle, or a set number of times of continuous shooting by the camera module 102 may be set as one shooting cycle.

In the same shooting period, the camera module 102 sends each shot image to the processor 103, and in particular, the camera module 102 sends the shot images in different directions to the processor 103 in the same shooting period. At this time, the processor 103 performs stitching processing on the images shot by the camera module 102 in the same shooting period to obtain a stitched image.

It can be understood that, because the camera module 102 can rotate along the horizontal direction, that is, can shoot along the same plane towards different directions, and the processor 102 splices the images shot towards different directions by the camera module 102, the obtained spliced images cover a faster imaging range. Therefore, based on the rotatable installation and rotatable shooting of the camera module 102 and the splicing processing of the images shot by the camera module 102 in different directions by the processor 103, the transverse shooting range of the electronic equipment can be expanded.

When the electronic equipment is applied to auxiliary reading, even if a user transversely unfolds and flatly places a book in front of the electronic equipment, the whole book can be shot by rotating the camera module 102 and splicing images of the processor 103 under the condition that the user does not need to adjust the placing direction of the electronic equipment, so that the user can conveniently read the book.

Furthermore, the electronic equipment provided by the application can shoot towards different directions along the same horizontal position, and can splice the shot images. The multi-direction shooting and the image splicing processing can expand the imaging width of the electronic equipment. When a user horizontally unfolds and places a book in front of the front face of the electronic equipment for reading, the position of the electronic equipment does not need to be adjusted in the process of turning pages left and right of the user, so that any area on the unfolded book can be shot, and the user can further conveniently read the book by pointing.
