Description
The technical field is as follows:
the invention provides a technology for adding a full screen to 3D photography of a mobile phone, and belongs to the field of communication engineering.
Background art:
the mobile phone is highly popularized in life, and brings great convenience to life of people. The camera function and the large screen display function of the mobile phone are two important indexes for measuring the quality of the mobile phone. Many current smart phones have multiple front and rear facing cameras and have proposed and adopted a full screen design. However, at present, the mobile phone mainly uses a plurality of cameras for the purpose of close-range, long-range and wide-angle photography, and a plurality of cameras are rarely used for the purpose of 3D photography. The 3D photography function of the existing mobile phone is basically that a plurality of photos are photographed by using the same camera and then 3D synthesized by using a specific software algorithm. So 3D photography is not a true sense. The real 3D photography is to shoot the same shot object by two cameras arranged in parallel, and because the two cameras arranged in parallel have a difference in photography angle, images shot by the two cameras are combined and displayed to generate a 3D image effect. At present, a plurality of cameras installed on a mobile phone are all arranged together closely, and even if the mobile phone is used for 3D photography, the required photography angle difference is difficult to obtain. Obviously, the 3D camera function can greatly enhance the user experience of the mobile phone. For example, in the aspect of face recognition, many mobile phones currently take 2D photos of faces through cameras, and then perform image recognition on the 2D photos. If a 2D photo of a face of a user faces a camera of a mobile phone, the face recognition of the mobile phone can directly consider that the photo is standing in front of the mobile phone, so that potential safety hazards exist. Some mobile phones, such as apple mobile phones, adopt a spot projection scanning technology to obtain 3D data of a human face for face recognition, which has a good safety performance, but the spot projection scanning technology requires additional complex components to be mounted on the mobile phone, which increases the cost of the mobile phone and occupies the space of the mobile phone. In particular, these mobile phones often have to leave a portion of the space on the front of the mobile phone in order to mount the front camera lens, the spot-projection scanning element, the speaker, and the associated sensors, and thus do not achieve a true full-screen display. For example, some mobile phones adopt a special-shaped full screen design with bang, and some mobile phones leave a whole narrow space above the front of the mobile phone. The bang space and the narrow strip space are used for mounting a front camera lens, a light spot projection scanning element, a loudspeaker and a related sensor. The other mobile phone adopts a lifting camera, when the mobile phone is not used, the camera is sunk to the top of the mobile phone, and when the mobile phone is used, the camera rises to extend out of the top of the mobile phone, so that the front space of the mobile phone is prevented from being occupied, and the mobile phone is left on a full screen. The special-shaped full-face screen with the bang is high in production cost, and extra requirements for displaying images by application software are increased; the mobile phone with a whole narrow space is difficult to be called as a true full-screen mobile phone, and people increasingly pay attention to the display effect of the mobile phone and face huge competitive pressure; the mobile phone adopting the lifting type camera has more fault risks, and the diameter depth of the camera cannot be designed by fully utilizing the thickness of the mobile phone. In addition, the front camera and the back camera of the existing mobile phone are usually two independent camera systems, and cannot be shared.
The invention provides a technology of 3D photography and full screen of a mobile phone, which enables the mobile phone to realize the function of 3D photography based on two cameras with enough photographic angle difference, the cameras, a loudspeaker and related sensors do not need to compete for the front space of the mobile phone with a display screen, and the front 3D camera and the back 3D camera on the mobile phone are mutually communicated and shared.
The invention content is as follows:
the invention aims to provide a mobile phone 3D photography and full screen technology, and aims to enable a mobile phone to realize real 3D imaging based on sufficient double-camera imaging angle difference, and parts such as a camera do not need to compete for space with a display screen on the front side of the mobile phone. In order to achieve the above object, the technology of the present invention includes a handset frame with two ears at the upper left end and the upper right end of the handset frame, respectively. The front and the back of each ear are provided with lens windows; the ear front lens window and the ear back lens window are circular glass windows with the same diameter; the connecting line of the circle center of the front lens window and the circle center of the back lens window on the same ear is vertical to the front plane of the mobile phone. Each ear is internally provided with a cylindrical inner cavity, and the axis of each cylindrical inner cavity is parallel to the long edge of the mobile phone and the front plane of the mobile phone; the diameter of the cylindrical inner cavity is slightly larger than that of the lens window; the front lens window and the back lens window on the same ear are communicated with the cylindrical inner cavity in the ear, and a connecting line of the circle center of the front lens window and the circle center of the back lens window is vertically intersected with the axis of the cylindrical inner cavity. A beveling cylinder with a reflector, a set of lens group and a photosensitive imaging element are sequentially arranged in the cylindrical cavity in each ear from top to bottom along the axial direction of the cylindrical cavity.
The axis of the oblique cutting cylinder is coincident with the axis of the cylindrical cavity in the ear, the oblique cutting surface of the oblique cutting cylinder forms an angle of 45 degrees with the axis of the oblique cutting cylinder, and the oblique cutting surface of the oblique cutting cylinder is the mirror surface of the reflector. The diameter of the oblique cylinder is almost the same as but slightly smaller than that of the cylindrical cavity in the ear, and the cylindrical surface of the oblique cylinder and the cavity wall of the cylindrical cavity in the ear are very smooth, so that the cylindrical surface of the oblique cylinder can closely cling to the cavity wall of the cylindrical cavity in the ear to rotate. The upper end of the oblique cutting cylinder is provided with a motor which is used for driving the oblique cutting cylinder to rotate in the cylindrical cavity in the ear. When the scene in front of the mobile phone needs to be shot, the motor drives the oblique cutting cylinder to rotate in the cylindrical inner cavity in the ear until the reflector of the oblique cutting cylinder faces the lens window in front of the ear; when the scene on the back of the mobile phone needs to be shot, the motor drives the oblique cylinder to rotate in the cylindrical inner cavity in the ear until the reflective mirror of the oblique cylinder faces the lens window on the back of the ear.
A guiding raised head is arranged on the cavity wall of the cylindrical cavity in each ear and close to the top of the cylindrical cavity, a guide rail groove is arranged on the cylindrical surface of the oblique cylinder and close to the top of the oblique cylinder and parallel to the circumference of the top of the oblique cylinder, and the guiding raised head on the cavity wall of the cylindrical cavity in each ear is just clamped in the guide rail groove of the oblique cylinder. In the process that the motor drives the beveled cylinder to rotate, when the guiding raised head on the cavity wall touches one extreme end of the guide rail groove of the beveled cylinder, the reflector of the beveled cylinder is aligned with one lens window of the ear; when the motor drives the chamfered cylinder to rotate reversely until the guide raised head on the cavity wall touches the other end of the guide rail groove of the chamfered cylinder, the mirror of the chamfered cylinder is aligned with the other lens window of the ear.
The center and focus of each lens of the lens group are on the axis of the cylindrical inner cavity. The center of the light-sensitive surface of the light-sensitive imaging element is also on the axis of the cylindrical cavity, and the light-sensitive surface is perpendicular to the axis of the cylindrical cavity. When the reflector of the oblique cylinder is aligned with one lens window of the ear, the light rays transmitted from the lens window can be changed by 90 degrees by the reflector and reflected to the lens group below the oblique cylinder, and then the light rays are focused on the photosensitive imaging element below the lens group through the lens group.
When the reflector of the oblique cylinder is aligned with one lens window of the ear, because the cylindrical surface of the oblique cylinder is tightly attached to the cavity wall of the cylindrical inner cavity, light rays transmitted from the other lens window of the ear can be blocked and sealed by the cylindrical surface of the oblique cylinder, and the photosensitive imaging work of the element below the oblique cylinder on the light rays from the first lens window cannot be influenced. Therefore, although the camera installed on a single ear of the mobile phone only has one set of reflector, lens group and photosensitive imaging element, the same camera can shoot the scene in front of the mobile phone and the scene at the back of the mobile phone by rotating the oblique cylinder to switch the direction of the reflector between the front lens window and the back lens window of the ear. At present, the front-shot lens and the back-shot lens of most mobile phones are two completely independent camera systems, and do not share any component with each other. In the technology of the invention, the front-shot lens and the back-shot lens on each ear of the mobile phone are actually shared by the same set of camera system, thereby reducing the cost and the installation space.
Because the upper left end and the upper right end of the mobile phone are respectively provided with an ear, and each ear is internally provided with a camera, when the cameras in the two ears shoot the same scene, for example, the scene in front of the mobile phone, the two cameras in the left ear and the right ear are separated by a distance of about the width of a mobile phone frame, so that the shooting angle difference of the same scene can be formed, and two shot synchronous images with the shooting angle difference can be used for 3D imaging. And because the cameras in the two ears can shoot the scene in front of the mobile phone and the scene in back of the mobile phone, the 3D shooting can be realized for the scene in front of the mobile phone and the scene in back of the mobile phone.
In addition, the loudspeaker and other related sensors of the mobile phone can be arranged at proper positions on the two ears without competing for space with the display screen on the front side of the mobile phone, so that the whole rectangular area on the front side of the mobile phone can be completely used for installing the display screen, and the real full-screen mobile phone is realized. Many current full-screen cell phones are not really true full-screen because they usually require a whole narrow strip, a bang area, or a water drop area on the front space of the cell phone for installing a front camera, a speaker, and other related sensors.
The technology of the invention can enable the mobile phone to realize the functions of shooting 3D photos, recording 3D videos and carrying out 3D imaging face recognition. When cameras in two ears of the mobile phone synchronously shoot photos of the same scene, the shot two synchronous image photos with shooting angle difference can be used for synthesizing a 3D photo; when cameras in two ears of the mobile phone synchronously shoot videos of the same scene, the shot two synchronous image videos with shooting angle difference can be used for synthesizing a 3D video; when cameras in two ears of the mobile phone are aligned to front lens windows of the ears and synchronously shoot faces in front of the mobile phone, two shot synchronous face images with shooting angle difference can be used for 3D imaging face recognition. It is to be emphasized that: the method of synthesizing a 3D photograph, the method of synthesizing a 3D video, and the method of 3D imaging face recognition based on two sets of synchronous image data having a difference in shooting angle are not the contents of the present invention; there are many existing correlation methods that can be used directly. The invention mainly comprises two ears carried by the mobile phone and a camera arranged in the ears; the contents of the invention enable the mobile phone to generate two groups of synchronous image data with enough shooting angle difference; however, it is difficult for the camera system of the existing mobile phone to generate two sets of synchronous image data with sufficient shooting angle difference, so that the existing mobile phone cannot realize a real 3D photo and a real 3D video based on the two sets of synchronous image data with the shooting angle difference.
Because the width of the mobile phone frame is limited, the distance between the two cameras installed in the ears at the upper left end and the upper right end of the mobile phone frame is also limited, and therefore when the two cameras synchronously shoot the same scene, the shooting angle difference of the two cameras is greatly dependent on the linear distance from the scene to the mobile phone. When the linear distance is too large, the difference between the shooting angles of the two cameras is so small that the two sets of synchronous image data captured cannot be effectively used for synthesizing a 3D image unless the imaging resolutions of the two cameras are both high enough to effectively distinguish the image difference caused by the small difference between the shooting angles. However, high imaging resolution means high manufacturing costs. Therefore, the inventive technique is mainly used to take 3D images of close-up scenes given the constraints of manufacturing costs. Generally speaking, when the head image of the user is shot by using the front-camera lens of the mobile phone, the distance is relatively short, and the shooting angle difference of the two cameras can be ensured to be large enough, so that a 3D image can be effectively synthesized to realize functions such as face recognition and 3D expression modeling. If only the short-distance scene in front of the mobile phone needs to be subjected to 3D shooting, each ear of the mobile phone frame in the technology of the invention can only have a front lens window without a back lens window, namely, the mobile phone can only carry out 3D shooting and shooting on the scene in front of the mobile phone. At the moment, the axis of the cylindrical inner cavity in each ear of the mobile phone frame passes through the center of the front lens window and is vertical to the front plane of the mobile phone, and the camera in each ear of the mobile phone frame does not need to be obliquely cut into a cylinder, and a reflector and a motor carried by the cylinder. In fact, if only a short-distance scene in front of the mobile phone needs to be photographed in a 3D manner, in the technology of the present invention, a front camera lens used by various current mobile phones can be directly installed in each ear of the mobile phone frame.
Technical indicators such as pixel resolution, aperture size, and the like of cameras in both ears of a mobile phone in the technology of the present invention, which are related to photographing performance and imaging quality, can be designed and decided according to the price, market, and functional location of the mobile phone.
Each component in the mobile phone 3D photography and full screen technology can be designed by adopting proper materials, shapes, sizes, quantities, colors and layout positions.
The technology for 3D photography and full screen of the mobile phone has the following beneficial effects: the technology of the invention can enable the mobile phone to realize the function of 3D photography based on two cameras with enough photography angle difference; the camera, the loudspeaker and the related sensor do not need to compete for the front space of the mobile phone with the display screen, namely the whole front space of the mobile phone can be used for installing the display screen, so that a real comprehensive screen is realized; in addition, the front camera and the back camera on each ear of the mobile phone are actually the same set of cameras which are shared, which is beneficial to saving cost and space.

Fig. 1 shows a main structure diagram of a mobile phone 3D photography plus full screen technology according to the present invention. The technology of the invention comprises a mobile phone frame (1), wherein the upper left end and the upper right end of the mobile phone frame (1) are respectively provided with an ear (2), and the rectangular space on the front surface of the mobile phone frame (1) is reserved for a display screen (3). The front of each ear (2) is provided with a front lens window (4), and the back of each ear (2) is provided with a back lens window (5). The loudspeaker (6) of the mobile phone is arranged at the proper position on the two ears (2), and other related sensors can be arranged at the proper position on the two ears (2) without competing for the space with the display screen (3) on the front side of the mobile phone, so that the front space of the mobile phone can be completely used for installing the display screen (3). The front lens window (4) of the ear (2) and the back lens window (5) of the ear (2) are circular glass windows with the same diameter; the line connecting the circle center of the front lens window (4) and the circle center of the back lens window (5) on the same ear (2) is vertical to the front plane of the mobile phone. The camera is arranged in the ear (2) and comprises a beveled cylinder (7), a set of lens group (10) and a photosensitive imaging element (11); the oblique cutting surface of the oblique cutting cylinder (7) is a reflective mirror (8), and the top of the oblique cutting cylinder (7) is provided with a motor (9) to drive the oblique cutting cylinder (7) to rotate, so that the reflective mirror (8) can be switched between being aligned with the front lens window (4) and being aligned with the back lens window (5). Because the upper left end and the upper right end of the mobile phone frame (1) are respectively provided with one ear (2), and each ear (2) is internally provided with one camera, when the cameras in the two ears (2) shoot the same scene, for example, the scene in front of the mobile phone is shot simultaneously, the two cameras in the left ear and the right ear (2) are separated by about the width of the mobile phone frame (1), so that the shooting angle difference of the same scene can be formed, and two shot synchronous images with the shooting angle difference can be used for 3D imaging. And because the cameras in the two ears (2) can shoot the scene in front of the mobile phone and the scene in back of the mobile phone, 3D shooting can be realized for the scene in front of the mobile phone and the scene in back of the mobile phone. In addition, the loudspeaker (6) and other related sensors of the mobile phone can be arranged at proper positions on the two ears (2) without competing for space with the display screen (3) on the front side of the mobile phone frame (1), so that the front space of the mobile phone frame (1) can be completely used for installing the display screen (3) to realize a true full-screen.
Fig. 2 shows an exemplary diagram of the cell phone ear and the cylindrical cavity in the 3D camera and full screen technology of the invention. Each ear (2) of the mobile phone frame (1) is internally provided with a cylindrical inner cavity (12), and the axis of the cylindrical inner cavity (12) is parallel to the long edge of the mobile phone frame (1) and is also parallel to the front plane of the mobile phone frame (1). The diameter of the cylindrical inner cavity (12) is slightly larger than the diameters of the lens windows (4) and (5). The front lens window (4) and the back lens window (5) on the same ear (2) are communicated with the cylindrical inner cavity (12) in the ear (2), and a connecting line of the circle center of the front lens window (4) and the circle center of the back lens window (5) is vertically intersected with the axis of the cylindrical inner cavity (12). A guiding projection (13) is arranged on the inner cavity wall of the cylindrical cavity (12) in each ear (2) and close to the top of the cylindrical cavity (12). The guide projection (13) serves to align the chamfered cylinder (7) mounted in the ear (2) after rotation precisely with the lens window (4) or (5) to be aligned. It is emphasized that, in order to make the example of fig. 2 clearer, fig. 2 shows only the main internal structure of the ear (2) at the upper left end of the handset frame (1), and does not show the camera assembly mounted in the ear (2).
FIG. 3 is a schematic diagram of an embodiment of a chamfered cylinder, a lens set and a photosensitive imaging device in 3D photography and full-face screen technology of a mobile phone according to the present invention. A beveling cylinder (7) with a reflector (8), a set of lens group (10) and a photosensitive imaging element (11) are sequentially arranged in a cylindrical cavity (12) in each ear (2) from top to bottom along the axial direction of the cylindrical cavity (12). The axis of the oblique cutting cylinder (7) is coincident with the axis of the cylindrical inner cavity (12) in the ear (2), the oblique cutting plane of the oblique cutting cylinder (7) forms an angle of 45 degrees with the axis of the oblique cutting cylinder (7), and the oblique cutting plane of the oblique cutting cylinder (7) is the mirror surface of the reflector (8). The diameter of the oblique cutting cylinder (7) is almost the same as that of the cylindrical inner cavity (12) in the ear (2) but is slightly smaller, and the cylindrical surface of the oblique cutting cylinder (7) and the cavity wall of the cylindrical inner cavity (12) in the ear (2) are both very smooth, so that the cylindrical surface of the oblique cutting cylinder (7) can be tightly attached to the cavity wall of the cylindrical inner cavity (12) in the ear (2) to rotate. The upper end of the oblique cutting cylinder (7) is provided with a motor (9) which is used for driving the oblique cutting cylinder (7) to rotate in a cylindrical inner cavity (12) in the ear (2). When the scene in front of the mobile phone needs to be shot, the motor (9) drives the chamfered cylinder (7) to rotate in the cylindrical inner cavity (12) in the ear (2) until the reflective mirror (8) of the chamfered cylinder (7) faces the front lens window (4) of the ear (2); when the scene on the back of the mobile phone needs to be shot, the motor (9) drives the oblique cutting cylinder (7) to rotate in the cylindrical inner cavity (12) in the ear (2) until the reflective mirror (9) of the oblique cutting cylinder (7) faces the back lens window (5) of the ear (2). A guide rail groove (14) is arranged on the cylindrical surface of the beveled cylinder (7), which is close to the top of the beveled cylinder (7) and is parallel to the circumference of the top of the beveled cylinder (7), and a guide raised head (13) on the inner cavity wall of the inner cylindrical inner cavity (12) of the ear (2) is just clamped in the guide rail groove (14) of the beveled cylinder (7). In the process that the motor (9) drives the beveled cylinder (7) to rotate, when the guiding raised head (13) on the cavity wall of the cylindrical inner cavity (12) touches the tail end of the guide rail groove (14) of the beveled cylinder (7), the reflector (8) of the beveled cylinder (7) is aligned with a lens window of the ear (2), for example, the front lens window (4); when the motor (9) drives the chamfered cylinder (7) to rotate reversely until the guiding raised head (13) on the cavity wall of the cylindrical inner cavity (12) touches the other end of the guide rail groove (14) of the chamfered cylinder (7), the reflector (8) of the chamfered cylinder (7) is aligned with the other lens window of the ear (2), for example, the back lens window (5). Each lens of the lens set (10) has a center and a focal point on the axis of the cylindrical cavity (12). The center of the light-sensitive surface of the photosensitive imaging element (11) is also on the axis of the cylindrical cavity (12), and the light-sensitive surface is perpendicular to the axis of the cylindrical cavity (12). When the reflector (8) of the oblique cylinder (7) is aligned with one lens window (4) or (5) of the ear (2), the light rays transmitted from the lens window can be changed by 90 degrees by the reflector (8) and reflected to a lens group (10) below the oblique cylinder (7), and then the light rays are focused on a photosensitive imaging element (11) below the lens group (10) through the lens group (10). When the reflector (8) of the chamfered cylinder (7) is aligned with one lens window of the ear (2), for example, the front lens window (4), because the cylindrical surface of the chamfered cylinder (7) is tightly attached to the cavity wall of the cylindrical inner cavity (12), the light penetrating from the other lens window of the ear (2), for example, the back lens window (5), can be blocked and sealed by the cylindrical surface of the chamfered cylinder (7), so that the photosensitive imaging work of the element below the chamfered cylinder (7) on the light from the first lens window cannot be influenced. Therefore, although the camera installed on a single ear (2) of the mobile phone frame (1) only has one set of reflector (8), lens group (10) and photosensitive imaging element (11), the same camera can shoot the scene in front of the mobile phone and the scene in the back of the mobile phone by rotating the beveling cylinder (7) to enable the reflector (8) to switch the direction between the front lens window (4) and the back lens window (5) of the ear (2). It is emphasized that, in order to make the example of fig. 3 clearer, fig. 3 shows only the components of the camera, namely the chamfered cylinder (7), the lens group (10) and the photosensitive imaging element (11), without the cylindrical cavity (12) in the ear (2) where these camera components are located.

a guide raised head is arranged on the cavity wall of the cylindrical inner cavity in each ear and close to the top of the cylindrical inner cavity, a guide rail groove is arranged on the cylindrical surface of the oblique cylinder and close to the top of the oblique cylinder and parallel to the circumference of the top of the oblique cylinder, the guide raised head on the cavity wall of the cylindrical inner cavity in each ear is just clamped in the guide rail groove of the oblique cylinder, when the guide raised head on the cavity wall touches one extreme end of the guide rail groove of the oblique cylinder in the process of driving the oblique cylinder to rotate by a motor, the reflector of the oblique cylinder is aligned with one lens window of the ear, and when the motor drives the oblique cylinder to reversely rotate until the guide raised head on the cavity wall touches the other extreme end of the guide rail groove of the oblique cylinder, the reflector of the oblique cylinder is aligned with the other lens window of the ear; the center and the focus of each lens of the lens group are on the axis of the cylindrical inner cavity; the center of the light-sensitive surface of the light-sensitive imaging element is also on the axis of the cylindrical cavity, and the light-sensitive surface is vertical to the axis of the cylindrical cavity; when the reflector of the oblique cylinder is aligned with one lens window of the ear, the light rays transmitted from the lens window can be changed by 90 degrees by the reflector and reflected to a lens group below the oblique cylinder, and then the light rays are focused on a photosensitive imaging element below the lens group through the lens group; when the reflector of the chamfered cylinder is aligned with one lens window of an ear, because the cylindrical surface of the chamfered cylinder is tightly attached to the cavity wall of the cylindrical inner cavity, light rays transmitted from the other lens window of the ear can be blocked and sealed by the cylindrical surface of the chamfered cylinder, so that the photosensitive imaging work of a component below the chamfered cylinder on the light rays from the first lens window cannot be influenced; therefore, although the camera installed on a single ear of the mobile phone only has one set of reflector, lens group and photosensitive imaging element, the same camera can shoot the scene in front of the mobile phone and the scene at the back of the mobile phone by rotating the oblique cylinder to switch the direction of the reflector between the front lens window and the back lens window of the ear; because the upper left end and the upper right end of the mobile phone are respectively provided with an ear and each ear is internally provided with a camera, when the cameras in the two ears shoot the same scene, for example, the scene in front of the mobile phone, the two cameras in the left ear and the right ear are separated by a distance of about one width of the mobile phone, so that the shooting angle difference of the same scene can be formed, and two shot synchronous images with the shooting angle difference can be used for 3D imaging; the cameras in the two ears can shoot the scene in front of the mobile phone and the scene in back of the mobile phone, so that the 3D shooting can be realized for the scene in front of the mobile phone and the scene in back of the mobile phone; in addition, the loudspeaker and other related sensors of the mobile phone can be arranged at proper positions on two ears without competing for space with the display screen on the front of the mobile phone, so that the front space of the mobile phone can be completely used for installing the display screen.
2. The mobile phone 3D photography and full screen technology of claim 1, wherein: when cameras in two ears of the mobile phone synchronously shoot photos of the same scene, the shot two synchronous image photos with shooting angle difference can be used for synthesizing 3D photos.
3. The mobile phone 3D photography and full screen technology of claim 1, wherein: when the cameras in the two ears of the mobile phone synchronously shoot videos of the same scene, the shot two synchronous image videos with shooting angle difference can be used for synthesizing a 3D video.
4. The mobile phone 3D photography and full screen technology of claim 1, wherein: each ear of the mobile phone frame can only have a front lens window without a back lens window, namely, the mobile phone can only take 3D pictures and take pictures of scenes in front of the mobile phone; the axis of the cylindrical inner cavity in each ear of the mobile phone frame passes through the center of the front lens window and is vertical to the front plane of the mobile phone; the camera in the ear of the mobile phone frame does not need to cut the cylinder and the reflector and the motor carried by the cylinder.
5. The mobile phone 3D photography and full screen technology of claim 1, wherein: when cameras in two ears of the mobile phone are aligned to front lens windows of the ears and synchronously shoot faces in front of the mobile phone, two shot synchronous face images with shooting angle difference can be used for 3D imaging face recognition.
6. The mobile phone 3D photography and full screen technology of claim 1, wherein: technical indicators such as pixel resolution, aperture size, etc. of the cameras in both ears of the mobile phone, which are related to photographing performance and imaging quality, can be designed and decided according to the price, market, and functional location of the mobile phone.
7. The mobile phone 3D photography and full screen technology of claim 1, wherein: the various components of the described technology may be designed with appropriate materials, shapes, sizes, quantities, colors, and placement positions.
