Fig. 1-2 are schematic structural diagrams of an image capturing device of an electronic device according to an embodiment of the present invention; fig. 3-4 are schematic diagrams illustrating a simple structure and an optical path of an image capturing device of an electronic apparatus according to an embodiment of the present invention; the image capturing device of the electronic device 1 provided by the embodiment includes an image collecting unit 10 and a movable light transmission unit 11; when the light transmission unit 11 moves into the electronic device 1, the rear light S1 on the side of the electronic device back plate 12 enters through the first incident surface M1 of the light transmission unit 11 and is output to the image acquisition unit 10 through the first exit surface M2, so that the image acquisition unit 10 can take a rear scene; when the light transmission unit 11 moves to the outside of the electronic device 1, a front light S2 on the screen (not shown in the drawings) side of the electronic device enters through the second incident surface M3 of the light transmission unit 11, and is reflected at least twice and then output from the second exit surface M4 to the image acquisition unit 10, so that the image acquisition unit 10 performs front scene shooting; wherein the first incident M1 coincides with the main optical axis of the first exit surface M2; the second incident plane M3 is parallel to the main optical axis of the second exit plane M4.
The image capturing unit 10 may be a device configured on the electronic device 1 and configured to perform an image capturing operation, and may be a camera, for example. The image capturing unit 10 in the embodiment of the present invention is fixedly disposed inside the electronic device, and the light-sensitive surface of the image capturing unit faces the back plate side of the electronic device, similar to a rear image capturing unit configured in an existing electronic device. The movable light transmission unit 11 may be a channel specially used for guiding light transmission, and may be an integrated optical device, the optical device is filled with a medium capable of supporting light transmission, and incident light may change a transmission path of light inside the light transmission unit 11 through refraction or reflection based on the material and the specific internal structure of the light transmission unit 11, so that the light is emitted from a desired exit surface. The light transmission unit 11 may also be an optical transmission channel formed by arranging a rear photographing lens and a front photographing lens in a movable structural member. This embodiment is not limited to this.
Optionally, as shown in fig. 1 and fig. 2, the light transmission unit 11 in this embodiment is disposed between the back plate 12 of the electronic device 1 and the image capturing unit 10, and is capable of moving between the back plate 12 of the electronic device 1 and the image capturing unit 10, an opening 121 is disposed on a side surface of the back plate of the electronic device 1, and the light transmission unit 11 is capable of moving from the inside of the electronic device 1 to the outside of the electronic device 1 through the opening 121, for example, fig. 1 shows a schematic structural diagram of an image capturing apparatus of the electronic device when the light transmission unit moves into the electronic device; fig. 2 is a schematic structural diagram of an image capturing device of an electronic device when the light transmission unit is moved out of the electronic device, and an opening 122 is disposed on a front surface of a back plate of the electronic device 1, so that when the light transmission unit 11 is moved into the electronic device, the light transmission unit 11 can receive a rear light S1 through the opening 122.
Specifically, as can be seen from the schematic diagrams of the simple structure and the optical path of the image capturing apparatus of the electronic device shown in fig. 3 and 4, in order to ensure that the image capturing unit can obtain the rear light ray S1 through the first incident surface M1 and the first exit surface M2 as much as possible, when the position of the light transmitting unit 11 needs to be ensured (as in the case shown in fig. 3) when the light transmitting unit 11 moves into the electronic device 1, the main optical axis of the first exit surface M2 coincides with the perpendicular bisector of the photosensitive surface of the image capturing unit 10, and the main optical axis of the first incident surface M1 coincides with the main optical axis of the first exit surface M2; in order to prevent the front light S2 from entering the image capturing unit 10, it is necessary to make the second incident surface M3 inside the electronic device to ensure that the front light S2 cannot enter the light transmitting unit 11. In order to ensure that the image capturing unit can obtain the front light ray S2 through the second incident plane M3 and the second exit plane M4 as much as possible, when the light transmission unit 11 needs to be moved to the outside of the electronic device 1 (as shown in fig. 7) when the position of the light transmission unit 11 is set, the main optical axis of the second exit plane M4 coincides with the perpendicular bisector of the light sensing plane of the image capturing unit 10, because the light sensing plane of the image capturing unit 10 is parallel to the back panel side of the electronic device when the front shooting is performed, the main optical axis of the second incident plane M3 is parallel to the main optical axis of the second exit plane M4, and in order to prevent the rear light ray S1 from entering the image capturing unit 10, the first incident plane M1 needs to be shielded by the back panel 12 of the electronic device, and it needs to ensure that the rear light ray S1 cannot enter the light transmission unit 11. Alternatively, each of the incident surface and the exit surface of the light transmission unit 10 may be a combination of one or more of a plane, a convex surface, or a concave surface.
Optionally, the specific light path direction of the image capturing device of this embodiment when performing post-capture and pre-capture is as follows: as shown in fig. 3, when the light transmission unit 11 moves into the electronic device 1, the image capturing apparatus of the embodiment performs post-scene capturing, and at this time, after the post-light S1 on the back panel side of the electronic device enters the light transmission unit 11 through the first incident plane M1 of the light transmission unit 11, the post-light S1 is projected to the first exit plane M2 in a straight line without being reflected and transmitted, and is output to the light sensing plane of the image capturing unit 10 from the first exit plane M2, and at this time, the image capturing unit 10 performs post-scene capturing based on the image captured by the light sensing plane. As shown in fig. 4, when the light transmission unit 11 moves to the outside of the electronic device 1, the image capturing apparatus of this embodiment performs front-end scene capturing, at this time, the front light S2 on the screen side of the electronic device enters the light transmission unit 11 through the second incident surface M3 of the light transmission unit, the front light S2 reflects at least twice (shown in fig. 2 as twice) inside the light transmission unit 11 and enters the second exit surface M4, the reflected front light S2 is output to the photosensitive surface of the image capturing unit 10 by the second exit surface M4, and at this time, the image capturing unit 10 performs front-end scene capturing based on the image captured by the photosensitive surface.
Optionally, in order to improve the shooting quality, a plurality of rear image capturing units may be optionally disposed in the electronic device, so that the number of the image capturing units 10 in the embodiment of the present invention may be one or more, when the number of the image capturing units 10 is multiple, the coverage area of each incident surface and each exit surface of the light transmitting unit 11 should be correspondingly increased, the photosensitive surface of all the image capturing units 10 should be covered, and correspondingly, the area of the opening 122 on the back plate of the electronic device should also be correspondingly increased.
The image shooting device provided by the embodiment of the invention adopts the fixed rear image acquisition unit and the movable light transmission unit, when the light transmission unit moves into the electronic equipment, the rear light detected by the backboard of the electronic equipment enters through the first incident surface of the light transmission unit and is output to the image acquisition unit through the first emergent surface, and at the moment, the image acquisition unit can shoot a rear scene; when the light transmission unit moves to the outside of the electronic device, the front light on the screen side of the electronic device enters through the second incident surface of the light transmission unit and is output to the image acquisition unit from the second emergent surface after being reflected for at least two times in the light transmission unit, and at the moment, the image acquisition unit can shoot front scenery. According to the scheme of the embodiment of the invention, the dual functions of front shooting and rear shooting of the electronic equipment can be realized through the rear image acquisition unit and the movable light transmission unit on the electronic equipment, an independent image acquisition unit is not required to be specially arranged for the front shooting, and the production cost of the electronic equipment is reduced while the complete full-screen design of the electronic equipment is realized.
Furthermore, when shooting is performed in a scene with weak light intensity, light supplement is generally required to be performed on shooting light through a flash lamp, and the conventional electronic equipment is generally provided with corresponding flash lamps for a rear camera and a front camera, and the front flash lamp is required to be the same as the front camera and arranged on the side of a display screen of the electronic equipment to occupy the position of the display screen. In order to realize the full screen design of the display screen, the embodiment of the invention can further optimize the image shooting device of the electronic equipment on the basis of the embodiment, and a flash lamp 13 is added on the image shooting device of the electronic equipment 1; the flash 13 is disposed on the light transmission unit 11, and when the light transmission unit 11 moves out of the electronic device 1, the flash 13 is configured to perform a light supplement operation on the front light S2 when the front light S2 is lower than a preset threshold. Since the flash 13 is used for supplementing light for the front light, the light emitting surface of the flash 13 faces the display screen side of the electronic device 1, and when the flash is disposed on the light transmission unit, it is required to ensure that the flash 13 is located outside the electronic device when the light transmission unit 11 moves to the outside of the electronic device 1. Specifically, the flash 13 may be disposed on the side of the light transmission unit as shown in fig. 5, or may be disposed above or below the light transmission unit. The advantage that sets up like this lies in, need not to occupy the space setting flash light of electronic equipment display screen, when realizing the complete full screen design of electronic equipment, has guaranteed leading shooting effect.
Fig. 6-7 are schematic diagrams of a simple structure and an optical path of an image capturing device of another electronic apparatus according to an embodiment of the invention; in the present embodiment, based on the above-mentioned embodiments, the specific structure and the optical path transmission manner when the light transmission unit 11 is not an integral optical device will be described in detail. The light transmission unit 11 of the present embodiment includes: a movable structure 111; a rear shooting mirror 112 and a front shooting mirror group 113 are arranged on the movable structural component 111; the first incident surface M1 and the first exit surface M2 are located on the rear photographing mirror 112; the second incident plane M3 and the second exit plane M4 are located on the front photographing lens group 113. The mirror surface of the rear shooting mirror 112 close to the electronic device back plate 12 is a first incident surface M1, and the mirror surface close to the image acquisition unit 10 is a first emergent surface M2; when the light transmission unit 11 moves out of the electronic device 1, the rear lens 112 is shielded by the back plate 12 of the electronic device, and no rear light enters the first incident surface M1. The front photographing lens group 113 comprises an incident mirror 1131, an exit mirror 1132, a first reflecting mirror 1133 and a second reflecting mirror 1134; the mirror surface of the incidence mirror 1131 close to the screen side of the electronic device 1 is a second incidence surface M3; the mirror surface of the exit mirror 1132 close to the image acquisition unit 10 is the second exit surface M4; the first mirror 1133 comprises a first reflection plane M5, and the second mirror 1134 comprises a second reflection plane M6; the front light ray S2 on the screen side of the electronic device 1 enters through the second incident plane M3, is projected onto the first reflection plane M5 by the incident mirror 1131, is reflected onto the second reflection plane M6 through the first reflection plane M5, is reflected onto the exit mirror 1132 through the second reflection plane M6, and is output to the image capturing unit 10 through the second exit plane M4 of the exit mirror 1132.
The rear photographing mirror 112, the incident mirror 1131, and the exit mirror 1132 may be one of a plane mirror, a convex lens, or a concave lens, or may be a combined lens formed by at least two of them. The first reflector 1133 and the second reflector 1134 are mainly used to reflect light on a reflection plane and change a light transmission path, and in order to reduce the loss of light, optical devices that can achieve total reflection, such as a plane mirror and a prism, may be selected as the first reflector 1133 and the second reflector 1134, and when the positions of the first reflector 1133 and the second reflector 1134 are set, the angles of light incident on the reflectors may be totally reflected on the reflectors as much as possible. The movable structure 111 may be a groove-shaped movable member made of alloy, plastic, etc. and may perform a retracting and ejecting operation between the inside and the outside of the electronic device through the opening on the side of the back panel of the electronic device based on the driving force of the driving unit, where the retracted state is shown in fig. 6 and the ejected state is shown in fig. 7.
Fig. 6 and 7 are schematic diagrams of simple structures of image capturing devices of the same electronic device in different states, where the structural elements in the two diagrams correspond to each other, and reference may be made to fig. 7 (or fig. 6) for structural elements not labeled in fig. 6 (or fig. 7).
In the image capturing apparatus according to an embodiment of the present invention, when the front view and the rear view are captured by the rear image capturing unit and the movable light transmitting unit on the electronic device, the movable optical transmitting unit may be an integrated optical device, and although the integrated optical device has good stability, the production and maintenance costs are high. The light transmission unit is composed of simple light lenses and movable structural parts, so that the production cost and the subsequent maintenance cost are greatly reduced.
Alternatively, on the basis of the foregoing embodiments, a specific case of the moving process of the light transmission unit 11 of the image capturing apparatus provided in the foregoing embodiments is described next. Specifically, the image capturing apparatus according to the embodiment of the present invention further includes a control unit and a driving unit; the control unit is used for controlling the driving unit to adjust the position of the light transmission unit 11 according to the shooting requirement to be switched.
The control unit may be an overall control unit of the electronic device, or may be a control unit specially used for controlling the movement of the light transmission unit 11. It may be a single chip, a Field Programmable Gate Array (FPGA), or a Central Processing Unit (CPU) of an electronic device. The driving unit may be a unit that provides a driving force for the movement of the movable mirror group 11, and may be, for example, a small driving motor, a push rod, a spring, or the like.
Specifically, the shooting requirements to be switched in this embodiment may include a front shooting requirement and a rear shooting requirement, and whether the shooting requirements to be switched are the front shooting requirement or the rear shooting requirement may be determined by a user clicking a camera switching icon on a camera application program interface. For example, if the current shooting mode is the rear-end shooting mode and the user clicks the camera conversion icon, the shooting requirement to be converted at this time is the front-end shooting requirement. Optionally, the shooting mode entered after the camera application is started may be a default shooting mode (e.g., a post shooting mode) of the system, or may be a shooting mode before the camera application is last turned off. Optionally, whether the shooting requirement to be switched is the front shooting requirement or the rear shooting requirement may also be determined by a user triggering a physical button on the electronic device, for example, a pop-up control button may be set for the light transmission unit 11, and if the user clicks the button, a pop-up instruction of the light transmission unit 11 is triggered and generated, where the pop-up instruction indicates that the shooting requirement of the user is the front shooting requirement.
Optionally, if the shooting requirement that needs to be switched currently is a pre-shooting requirement, the control unit may generate a first control instruction, and send the first control instruction to the driving unit, and the driving unit may control the light transmission unit 11 to move from the inside of the electronic device 1 to a preset position outside the electronic device 1 based on the first control instruction, that is, move the light transmission unit 11 from the position shown in fig. 1 to the position shown in fig. 2. If the current shooting requirement needing to be switched is a post-shooting requirement, the control unit may generate a second control instruction, and send the second control instruction to the driving unit, and the driving unit may control the light transmission unit 11 to move from the outside of the electronic device 1 to a preset position inside the electronic device 1, that is, move the light transmission unit 11 from the position shown in fig. 2 to the position shown in fig. 1, based on the second control instruction.
According to the image shooting device provided by the embodiment of the invention, the driving unit can be controlled by the control unit according to the shooting requirement required to be switched at present to adjust the position of the movable light transmission unit in the image shooting device provided by any embodiment of the invention, so that the image acquisition unit can shoot images according to the shooting requirement to be switched. The device provides guarantee for completing front scene shooting and rear scene shooting through one image acquisition unit and the movable light transmission unit, and reduces the production cost of the electronic equipment while realizing the complete full-screen design of the electronic equipment.
Fig. 8 is a flowchart of an image capturing method provided by an embodiment of the present invention, which is applicable to the case of capturing an image by the image capturing apparatus described in the foregoing embodiments, and can be specifically executed by a control unit in the image capturing apparatus. As shown in fig. 8, the method specifically includes the following steps:
s801, if the shooting requirement to be switched is detected to be front shooting, controlling the driving unit to move the light transmission unit from the first position to the second position.
Wherein, the shooting requirement to be switched can include two kinds of front shooting requirements and rear shooting requirements. Optionally, there are many methods for detecting that the shooting requirement to be switched is a pre-shooting requirement in this step, and this embodiment is not limited thereto, and one possible implementation manner may be to detect a pop-up instruction of the light transmission unit; specifically, the pop-up instruction of the light transmission unit may be automatically generated after a user triggers a physical button on the electronic device. For example, a pop-up control button may be set for the light transmission unit, if the user clicks the button, a pop-up instruction of the light transmission unit is generated and transmitted to the control unit, and if the control unit receives the pop-up instruction, it indicates that the pop-up instruction of the light transmission unit is detected, that is, it is detected that the shooting requirement to be switched is front shooting. Another possible implementation may be to receive a pre-capture instruction transmitted by the camera application. Specifically, the pre-shooting instruction may be automatically generated after the user triggers a camera conversion icon on the camera application program interface. For example, a camera conversion icon for performing pre-and post-view conversion is arranged on a camera application program interface, if the current shooting mode is the post-shooting mode and a user clicks the camera conversion icon, a pre-shooting instruction is automatically generated by a relevant process of an application program and transmitted to the control unit, and if the control unit receives the pre-shooting instruction, it is determined that the shooting requirement to be converted is detected as pre-shooting.
Optionally, if it is detected that the current shooting requirement to be switched is a pre-shooting requirement, the control unit may generate a first control instruction, and send the first control instruction to the driving unit, and the driving unit may control, based on the first control instruction, the light transmission unit to move from the first position (i.e., inside the electronic device) to a preset position of the second position (i.e., outside the electronic device), that is, move the light transmission unit from the position shown in fig. 1 to the position shown in fig. 2.
Optionally, in order to prevent the light transmission unit from being damaged, the light transmission units in the embodiments of the present invention are all located inside the electronic device in a scene without front-end shooting, that is, all located at the second position. Therefore, after the step of moving the light transmission unit from the first position to the second position, the method further includes: and if the shooting requirement to be switched is detected to be post shooting or the camera application program is detected to be closed, controlling the driving unit to move the light transmission unit from the second position to the first position. Specifically, if it is detected that the current shooting requirement to be switched is a post-shooting requirement, or the camera application program is already closed, the control unit may generate a second control instruction, and send the second control instruction to the driving unit, and the driving unit may control the light transmission unit to move from the second position (i.e., outside the electronic device) to the preset position of the first position (i.e., inside the electronic device) based on the second control instruction, that is, move the light transmission unit from the position shown in fig. 2 to the position shown in fig. 1.
It should be noted that the manner of detecting that the current shooting requirement to be switched is the rear shooting requirement by the control unit of the electronic device is similar to the manner of detecting that the shooting requirement to be switched is the front shooting requirement, for example, the control unit may detect a retraction instruction of the light transmission unit; or receiving a post shooting instruction transmitted by the camera application program. There are also many ways for the control unit of the electronic device to detect that the camera application has been closed, for example, if it is detected that the camera application is deleted from the system running process, it indicates that the camera application has been detected to be closed; if the background running time of the camera application program is detected to exceed the preset time length, the camera application program is detected to be closed; it may also be that the camera application is detected to have been closed when the user does not use the camera application for a preset time period.
It should be noted that if the pre-shooting is detected through the pop-up instruction of the light transmission unit, it indicates that the pre-shooting requirement is triggered by the user through a physical key on the electronic device, and at this time, the camera application program is not necessarily started in the electronic device, so that it is necessary for the operating system of the electronic device to detect whether the started camera shooting program exists currently, if so, the operation of S802 below may be directly performed, if not, the preset camera application program needs to be started first, and then the operation of S802 below is performed, where the preset camera application program may be a camera application program carried by the operating system of the electronic device, or may be a user-defined setting according to a requirement; the camera application program frequently used by the user can be used as the preset camera application program according to the use habit of the user.
And S802, responding to a shooting instruction of the camera application program, and controlling the image acquisition unit to shoot images based on the moved light transmission unit.
Optionally, there are many triggering manners for generating the shooting instruction by the related process of the camera application, for example, the triggering manner may be generated by a user clicking a shooting key on a shooting interface of the camera application; the method can also be generated by triggering of a user through preset gestures, expressions and voices. Without limitation to this embodiment, after the camera application program generates a shooting instruction, the shooting instruction is sent to the control unit of the electronic device, and the control unit starts the image capturing unit of the image capturing apparatus to capture an image based on the light transmission unit moved in S801 in response to the shooting instruction. Since S801 is to move the light transmission unit from the first position to the second position, this step controls the image capturing unit to perform front scene capturing based on the moved light transmission unit after responding to a capturing instruction of the camera application. If the light transmission unit is moved from the second position to the first position in S801, the image acquisition unit is controlled to perform post-scene shooting based on the moved light transmission unit after the step responds to a shooting instruction of the camera application program.
According to the image shooting method provided by the embodiment of the invention, if the control unit of the image shooting device detects that the shooting requirement to be switched is front shooting, the control unit controls the driving unit to move the light transmission unit from the first position to the second position, and then after a shooting instruction of a camera application program is received, the control unit responds to the shooting instruction and controls the image acquisition unit to carry out image shooting operation based on the moved light transmission unit.
