Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic product accessories, and particularly relates to a photographing system and a terminal accessory. BACKGROUND

[0002] The pinhole camera is small in size and high in concealment, and is usually difficult to be found by naked eyes. People urgently need a simple and portable pinhole camera detection product for daily use. At present, the industry uses a terminal such as a mobile phone for photographing camera detection, but the detection is difficult and the detection accuracy is low. SUMMARY

[0003] The present application provides a photographing system and a terminal accessory, which are low in detection difficulty and high in detection accuracy.

[0004] In a first aspect, the present application provides a photographing system, which comprises a terminal and a terminal accessory. The terminal comprises a camera and a flash. The terminal accessory comprises a first base and a light guide piece. The first base has a first camera hole. The light guide piece is fixed to the first base. The light guide piece comprises an entrance light part and an exit light part. The entrance light part and the exit light part are arranged oppositely and both are exposed relative to the first base. The distance between the exit light part and the first camera hole is smaller than the distance between the entrance light part and the first camera hole. The terminal accessory is detachably fixed to the terminal. The first camera hole is opposite to the camera. The entrance light part is opposite to the flash.

[0005] In the present application, the positions of the entrance light part, the exit light part and the first camera hole of the light guide piece of the terminal accessory are arranged, so that the light guide piece can guide the light emitted by the flash of the terminal to the position around the camera, and the light is emitted from the area around the camera. When the terminal system detects a stolen camera, the light emitted by the flash and reflected back by the stolen camera is mainly concentrated in the area where the camera of the terminal is located and the surrounding area. Therefore, the light reflected back by the stolen camera is easily captured by the camera, the receiving amount of the light reflected back by the stolen camera is increased, and the photographing system is simple, fast and accurate in identifying the stolen camera.

[0006] For example, the light guide piece can further comprise a light guide plate piece and a light guide boss. The entrance light part can be formed on the bottom surface of the light guide plate piece, and the exit light part is formed on the top surface of the light guide boss. The distance between the exit light part and the first camera hole is the distance between the geometric center of the exit light part and the center line of the first camera hole. The distance between the entrance light part and the first camera hole is the distance between the geometric center of the entrance light part and the center line of the first camera hole. The camera can receive external light through the first camera hole, that is, it can be considered that the first camera hole is opposite to the camera. The light emitted by the flash can enter the light guide piece through the entrance light part and be emitted from the exit light part of the light guide piece, that is, it can be considered that the entrance light part of the light guide piece is opposite to the flash.

[0007] In some possible implementation manners, the light emitting portion is arranged around the first camera hole. In this case, the light emitting portion is arranged at a small distance from the first camera hole.

[0008] In some possible implementation manners, the photographing system provided in the present application can further include a terminal and a terminal accessory. The terminal includes a camera and a flash. The terminal accessory includes a first base and a light guide member. The first base has a first camera hole. The light guide member is fixed to the first base. The light guide member includes a light entering portion and a light emitting portion. Both the light entering portion and the light emitting portion are exposed relative to the first base. The light guide member is provided with a light reflecting material except for the light entering portion and the light emitting portion. The terminal accessory is detachably fixed to the terminal. When the terminal accessory is fixed to the terminal, the first camera hole is opposite to the camera, the light entering portion is opposite to the flash, and the light emitting portion is arranged around the first camera hole. Light emitted by the flash enters the light guide member through the light entering portion and is emitted through the light emitting portion.

[0009] In the present application, the light entering portion of the light guide member is opposite to the flash, the light emitting portion is arranged around the first camera hole, and the first camera hole is opposite to the camera. Therefore, the light guide member can guide the light emitted by the terminal flash to a position around the camera, and the light is emitted from the position around the camera. When the terminal system detects a stolen camera, the light emitted by the flash and reflected back by the stolen camera is mainly concentrated in the area where the camera of the terminal is located and the surrounding area. Therefore, the light reflected back by the stolen camera is easily captured by the camera, the receiving amount of the light reflected back by the stolen camera by the camera is increased, and the accuracy and convenience of the photographing system in identifying the stolen camera are improved. In addition, the light reflecting material is arranged on the other part of the light guide member except for the light entering portion and the light emitting portion. Therefore, the light entering the light guide member from the light entering portion is reflected multiple times in the light guide member and is emitted only or mainly from the light emitting portion. Therefore, the light escaping to the air from the area other than the light emitting portion can be prevented, and the light intensity of the light emitted from the light guide member is improved.

[0010] In some possible implementation manners, the light reflecting material can be in the form of a reflective film and covers the other surface of the light guide member except for the light entering portion and the light emitting portion.

[0011] In some possible implementation manners, the light emitting portion is provided with a texture structure. The texture structure is used to make the light emitting angle of the light beam emitted from the light emitting portion less than or equal to the field of view angle of the camera.

[0012] In the present implementation manner, the texture structure can make the light in the light guide member be emitted along a preset angle, and the light is constrained in the receiving field of view of the camera. Therefore, the light reflected back by the stolen camera is more easily received by the camera, and the identification success rate of the stolen camera by the photographing system is improved.

On the other hand, the reflective film of the light guide member covers the hole wall of the light transmission hole, so that the light in the light guide member cannot be emitted from the hole wall of the light transmission hole and interfere with the detection process of the shooting system on the hidden camera, thereby improving the detection accuracy of the shooting system.

[0025] In the implementation manners, the diaphragm can converge light, the light emitted by the flash passes through the diaphragm, and a light spot can be formed when the light is irradiated on the background (for example, a wall surface), so that the picture including the light spot taken by the camera can have a sunset lamp effect.

For example, when the terminal accessory is installed on the terminal, the first accessory can be separated from the shell to protect the terminal by the shell, or the first accessory can be fixed to the shell to protect the terminal by the shell and improve or increase the photographing function of the terminal by the first accessory, thereby improving the user experience of the photographing system.

[0031] In some possible implementation manners, the connection mode between the first connecting piece and the basic connecting piece is magnetic attraction connection, clamping connection or threaded connection.

[0032] When the connection mode between the first connecting piece and the basic connecting piece of the shell is magnetic attraction connection, the first accessory has no damage or little damage to the shell during disassembly and assembly.

When the terminal system detects the hidden camera, the light emitted from the light outlet irradiates the hidden camera, and the light reflected back by the hidden camera is mainly concentrated in the area where the terminal camera is located and the surrounding area, so that the light reflected back by the hidden camera is easily captured by the camera, thereby increasing the amount of light received by the camera from the hidden camera, and improving the accuracy and convenience of the camera in identifying the hidden camera. Wherein, the light reflection material is arranged on the surface of the light guide member except the light inlet and the light outlet, so that the light entering the light guide member from the light inlet is reflected multiple times in the light guide member, and then is emitted from the light outlet, thereby preventing the light from escaping to the air from the area other than the light outlet to cause loss, and improving the light intensity of the light emitted from the light guide member.

The cover plate 112 and the side plate 111 enclose a containing space for containing the terminal 20. The first accessory body 2 can be fixed to the top side of the cover plate 112. In the embodiments of the application, the “top” and “bottom” directions of the structures of the terminal accessory 10 are relative directional descriptions, wherein the direction from the shell 1 to the first accessory body 2 is the direction from the “bottom” to the “top”. For example, the first accessory body 2 is located at the top side of the shell 1, and the shell 1 is located at the bottom side of the first accessory body 2.

[0115] In the embodiments, the shell 1 can be detachably sleeved on the terminal 20 to protect the terminal 20. The first accessory body 2 can be arranged corresponding to the camera 201 and the flash 202 of the terminal 20 to improve or increase the photographing function of the terminal 20.

[0116] Please refer to Figure 34 to Figure 39 and Figure 1 to Figure 33 , Figure 1 to Figure 39 isFigure 40 A partially exploded view of the terminal accessory 10 is shown.

[0117] In some embodiments, the first accessory 2 is detachably fixed to the housing 1. In the present embodiment, since the first accessory 2 of the terminal accessory 10 is detachably connected to the housing 1, the terminal accessory 10 can have multiple use states. For example, when the terminal accessory 10 is mounted on the terminal 20, the first accessory 2 can be detached from the housing 1 to protect the terminal 20 by the housing 1, or the first accessory 2 can be fixed to the housing 1 to not only protect the terminal 20 by the housing 1 but also improve or increase the photographing function of the terminal 20 by the first accessory 2, so as to improve the user experience of the photographing system 100.

[0118] For example, the detachable connection between the first accessory 2 and the housing 1 can be achieved by magnetic connection, clamping connection, threaded connection, or the like, which is not strictly limited in the present embodiment. In other embodiments, the first accessory 2 can also be fixed to the housing 1 by a non-detachable connection.

[0119] Please refer to Figure 41 and Figure 40 , Figure 41 is Figure 40 a partially exploded view of the housing 1, Figure 42 is Figure 41 a sectional view of the housing 1 along A-A.

[0120] In some embodiments, the housing 1 includes a housing base 11 and a base connector 12. The housing base 11 includes the side plate 111 and the cover plate 112 described above. The housing 1 has a window hole 13, which penetrates the housing base 11 and the base connector 12. The cover plate 112 is provided with a mounting hole 1121, which is part of the window hole 13. The mounting hole 1121 can be circular in shape. In other embodiments, the mounting hole 1121 can also be square or other polygons, which is not strictly limited in the present embodiment.

[0121] In some embodiments, the housing base 11 further includes a base boss 113, which is fixed to the top surface of the cover plate 112 and surrounds the mounting hole 1121. The cover plate 112 is further provided with at least one groove 1122, which surrounds and is close to the base boss 113 and the opening of the groove 1122 is located on the top surface of the cover plate 112.

[0122] In some embodiments, the base connector 12 is used to support the detachable connection between the housing 1 and the first accessory 2. In the present embodiment, the detachable connection between the first accessory 2 and the housing 1 is achieved by magnetic connection as an example.

[0123] Exemplarily, the base connector 12 can include a magnetic element 121, a magnetic isolation sheet 122, and a first adhesive layer 123. The magnetic element 121 can be substantially annular. The magnetic element 121 includes a top plate 1211 and a base outer ring wall 1212 connected to a peripheral edge of the top plate 1211 and bent towards a bottom side of the top plate 1211. The magnetic element 121 further includes at least one protrusion 1213 fixedly connected to the base outer ring wall 1212. The first adhesive layer 123 can be substantially annular. The first adhesive layer 123 is located on an inner side of the base outer ring wall 1212 and fixed to the bottom side of the top plate 1211. The magnetic isolation sheet 122 can be substantially annular. The magnetic isolation sheet 122 is located on the inner side of the base outer ring wall 1212 and fixed to a bottom side of the first adhesive layer 123, i.e., the magnetic isolation sheet 122 is fixedly connected to the top plate 1211 through the first adhesive layer 123. The magnetic isolation sheet 122 can be fixedly connected to the base protrusion 113 through a second adhesive layer (not shown in the figure), and the base outer ring wall 1212 is arranged around the base protrusion 113 of the cover plate 112, and the protrusion 1213 is clamped into the groove 1122 of the cover plate 112. The first adhesive layer 123 and / or the second adhesive layer can be glue dispensing or adhesive backing. The base connector 12 can be substantially annular as a whole, and an inner side space of the base connector 12 is part of the window hole 13.

[0124] In the embodiment, the magnetic element 121 is clamped into the groove 1122 of the cover plate 112 through the protrusion 1213, so that the magnetic element 121 is easy to align with the cover plate 112 during installation. In some embodiments, the protrusion 1213 of the magnetic element 121 and the groove 1122 of the cover plate 112 can form a snap structure with a limiting function and a connecting function, so that the connection stability of the magnetic element 121 and the cover plate 112 after assembly is higher.

[0125] In some embodiments, the material of the magnetic element 121 can be magnetic stainless steel, so that the magnetic element 121 is not easy to rust, which is conducive to improving the service life of the shell 1 and the terminal accessory 10. Exemplarily, the magnetic element 121 can be made of 430 stainless steel by forging and pressing process, or made of martensitic precipitation hardening stainless steel (17-4PH raw material) by metal powder injection molding (MIM) process. In other embodiments, the magnetic element 121 can also be a magnet made of ferrous alloy, cobalt alloy, nickel alloy, or manganese alloy, and a corrosion-resistant film layer can be arranged on the surface of the magnetic element 121. The corrosion-resistant film layer can be formed by, for example, paint spraying, physical vapor deposition, electroplating, chemical treatment, etc. The arrangement of the corrosion-resistant film layer makes the magnetic element 121 not easy to rust, which is conducive to improving the service life of the terminal accessory 10.

[0126] In some embodiments, the magnetic isolation sheet 122 is used to block the magnetic field to avoid interference of the magnetic field of the magnetic element 121 and / or the magnetic field of the first ligand 2 to the internal devices of the terminal 20. The material of the magnetic isolation sheet 122 can be, but is not limited to, engineering pure iron, magnetically conductive stainless steel or low carbon steel. Among them, the magnetic isolation sheet 122 can adopt SPCC steel (i.e. general cold-rolled carbon steel sheet) material.

[0127] In other embodiments, the magnetic element 121 can also not be provided with the protrusion 1213, and the shell base 11 can also not be provided with the recess 1122, and the magnetic element 121 and the shell base 11 can be aligned by other ways, which are not strictly limited in the embodiments of the present application.

[0128] Please refer to Figure 1 , Figure 2 is Figure 1 the exploded structural view of the first ligand 2.

[0129] In some embodiments, the first ligand 2 includes a first base 21 and a light guide 22. Among them, the first base 21 can include a first bottom plate 211, a first connecting piece 212 and a first cover 213. The first bottom plate 211 can be provided with a first recess 2111, a second recess 2112, a first through hole 2113 and a second through hole 2114. The openings of the first recess 2111 and the second recess 2112 are located on the top side of the first bottom plate 211. The first recess 2111 can be arranged on the periphery of the first bottom plate 211, and the first recess 2111 can include a plurality of arc-shaped grooves arranged at intervals. The second recess 2112 is located on the inner side of the first recess 2111. The first through hole 2113 and the second through hole 2114 are arranged at the bottom of the second recess 2112 and communicate with the second recess 2112. The first connecting piece 212 can include a plurality of spaced magnets, and the shape of the magnet can be arc-shaped. Among them, the first connecting piece 212 can be a magnet made of magnetic material such as ferrous alloy, cobalt alloy, nickel alloy or manganese alloy. The first cover 213 includes a first top plate 2131 and a first outer ring wall 2132, the first outer ring wall 2132 is connected to the periphery of the first top plate 2131, and is bent towards the bottom side of the first top plate 2131 relative to the first top plate 2131, and the first top plate 2131 is provided with a third through hole 2131a. Among them, the first bottom plate 211 and the first cover 213 can adopt a material that is not transparent, which is not strictly limited in the embodiments of the present application.

[0130] Please refer to Figure 2 , Figure 1 is Figure 1 the structural view of the light guide 22, Figure 2 is Figure 2 the structural view of the light guide 22 at another angle, Figure 3 isFigure 3 A schematic view of a cross-sectional structure of the light guide member 22 along B-B.

[0131] In some embodiments, the light guide member 22 comprises an incident light portion 221 and an emergent light portion 222, which are oppositely arranged. For example, the light guide member 22 can further comprise a light guide plate member 2231 and a light guide boss 2232, which is protruded from the top side of the light guide plate member 2231. The light guide plate member 2231 and the light guide boss 2232 can jointly form a light guide member body 223, which can be an integrally formed structure. The incident light portion 221 can be formed on the bottom surface of the light guide plate member 2231, and the emergent light portion 222 can be formed on the top surface of the light guide boss 2232. The material of the light guide member body 223 can be polymethyl methacrylate, polycarbonate, epoxy resin, optical glass, or other light guide materials, so that the light guide member 22 can well realize light transmission.

[0132] The light guide member 22 is provided with a light reflection material (not shown in the figure) on other portions except the incident light portion 221 and the emergent light portion 222. The light reflection material can be in the form of a reflective film (not shown in the figure) covering the other surfaces of the light guide member 22 except the incident light portion 221 and the emergent light portion 222. The light reflection material provided on the other surfaces of the light guide member 22 except the incident light portion 221 and the emergent light portion 222 can make the light entering the light guide member 22 through the incident light portion 221 be reflected multiple times in the light guide member 22 and then be emitted only or mostly from the emergent light portion 222, so as to prevent the light from escaping into the air from the areas other than the emergent light portion 222 and causing loss, thereby improving the light intensity of the light emitted from the emergent light portion 222 of the light guide member 22.

[0133] For example, the emergent light portion 222 of the light guide member 22 is provided with a texture structure 2221 for converging light. That is, the texture structure 2221 on the emergent light portion 222 can focus the light emitted from the emergent light portion 222, thereby narrowing the light emitting angle of the light beam emitted from the emergent light portion 222 and improving the light intensity of the light emitted from the light guide member 22.

[0134] The texture structure 2221 can include a plurality of light collecting prisms 2221a, each of which is annular. The cross-sectional shape of the light collecting prisms 2221a can be triangular, semicircular, or other structures that exhibit light collecting properties. The plurality of light collecting prisms 2221a are arranged in sequence from inside to outside. The cross-sectional shape of the plurality of light collecting prisms 2221a can be different. The specific cross-sectional shape of each light collecting prism 2221a can be adjusted according to the actual light path of the light guide piece 22, so that each light collecting prism 2221a at different positions can reasonably change the light path of the outgoing light, achieving light convergence. For example, the plurality of light collecting prisms 2221a can be arranged at equal intervals to reduce the design difficulty of the texture structure 2221. In other embodiments, the plurality of light collecting prisms 2221a can also be arranged at unequal intervals, which is not strictly limited in the embodiments of the present application.

[0135] For example, the light guide piece 22 can also be provided with a light transmission hole 224 for allowing external light to pass through the light guide piece 22. For example, the light transmission hole 224 can pass through the light emitting portion 222, that is, the light emitting portion 222 is arranged around the light transmission hole 224. For example, the light transmission hole 224 can pass through the light guide boss 2232 and the light guide plate 2231. The reflective film can also be covered on the hole wall of the light transmission hole 224, so that the light inside the light guide piece 22 will not be emitted from the hole wall of the light transmission hole 224, reducing light loss and improving the light intensity of the light emitted from the light guide piece 22.

[0136] For example, the distance between the light emitting portion 222 and the light transmission hole 224 is less than the distance between the light receiving portion 221 and the light transmission hole 224. The distance between the light emitting portion 222 and the light transmission hole 224 is the distance between the geometric center of the light emitting portion 222 and the center line of the light transmission hole 224, and the distance between the light receiving portion 221 and the light transmission hole 224 is the distance between the geometric center of the light receiving portion 221 and the center line of the light transmission hole 224. In the following description, the distance between the light emitting portion 222, the light receiving portion 221 and other hole structures is understood similarly, which will not be described hereinafter. In this embodiment, since the light emitting portion 222 is arranged around the light transmission hole 224, the distance between the light emitting portion 222 and the light transmission hole 224 is very small, which can be zero in some embodiments.

[0137] The light guide piece 22 can also be provided with a relief space 225 for avoiding other structures when the light guide piece 22 is installed on other structures, so as to reduce the installation difficulty of the light guide piece 22. In some embodiments, the relief space 225 can also function as positioning and / or limiting when the light guide piece 22 is assembled with other structures.

[0138] Please refer to Figure 2 and Figure 4 , Figure 5 is Figure 4A cross-sectional structure schematic diagram of the first ligand 2 along C-C, Figure 3 is Figure 5 A cross-sectional structure schematic diagram of the first ligand 2 along D-D.

[0139] In some embodiments, in the first ligand 2, the first connecting piece 212 is installed in the first recessed groove 2111 of the first bottom plate 211, and the gap between the first connecting piece 212 and the groove wall of the first recessed groove 2111 can be fixed by glue or back glue (not shown in the figure). Among them, the plurality of magnets included in the first connecting piece 212 are adapted to the shape of the plurality of arc-shaped grooves of the first recessed groove 2111. In other embodiments, the number and shape of the magnets of the first connecting piece 212 can also have other design ways, for example, designed as an integral annular magnet, and the shape of the first recessed groove 2111 is adapted to the shape of the first connecting piece 212.

[0140] The light guide piece 22 is installed in the second recessed groove 2112 of the first bottom plate 211. Among them, the light inlet part 221 of the light guide piece 22 faces the second through hole 2114 of the first bottom plate 211, and the light inlet part 221 of the light guide piece 22 is exposed relative to the first bottom plate 211. The light transmission hole 224 of the light guide piece 22 is communicated with the first through hole 2113 of the first bottom plate 211, and the light outlet part 222 of the light guide piece 22 is arranged away from the first bottom plate 211.

[0141] The first cover body 213 is installed on the top side of the light guide piece 22 and the first bottom plate 211. The first top plate 2131 of the first cover body 213 is arranged opposite to the first bottom plate 211, and the light guide piece 22 is located between the first top plate 2131 and the first bottom plate 211. The first outer ring wall 2132 of the first cover body 213 is arranged around the first bottom plate 211. The light guide boss 2232 of the light guide piece 22 is at least partially located in the third through hole 2131a of the first cover body 213, and the light outlet part 222 of the light guide piece 22 is exposed relative to the first cover body 213.

[0142] In this embodiment, the light transmission hole 224 of the light guide piece 22 and the first through hole 2113 of the first bottom plate 211 are communicated to form a first imaging hole 214 of the first base 21, in other words, the first imaging hole 214 includes the light transmission hole 224 and the first through hole 2113. The light outlet part 222 of the light guide piece 22 is arranged around the first imaging hole 214, and the distance between the light outlet part 222 of the light guide piece 22 and the first imaging hole 214 is very small, even zero, and the distance between the light outlet part 222 of the light guide piece 22 and the first imaging hole 214 is smaller than the distance between the light inlet part 221 and the first imaging hole 214. The light inlet part 221 and the light outlet part 222 of the light guide piece 22 are exposed relative to the first base 21. The light guide piece 22 can be fixedly connected to the first bottom plate 211 by bonding, buckling connection and the like, so that the light guide piece 22 is fixed to the first base 21.

[0143] It can be understood that, for the first camera hole 214 of the first base 21, the first base 21 is the basic structure of the first ligand 2, the first base 21 has a basic space for arranging the first camera hole 214, when the light guide member 22 is partially located in the basic space, part of the structure of the light guide member 22 (for example, the light transmission hole 224 described above) can participate in the formation of the first camera hole 214, when the light guide member 22 is completely located outside the basic space, the first camera hole 214 is formed by the basic space, and the light guide member 22 does not participate in the formation of the first camera hole 214. For example, in other embodiments, the first camera hole 214 can also be completely formed by the light transmission hole 224, or formed by other hole structures of the first base 21, and the embodiments of the present application do not strictly limit the structure of the first camera hole 214.

[0144] Please refer to Figure 3 and Figure 6 again, in some embodiments, a plurality of protrusions 2115 are arranged at the periphery of the first bottom plate 211, and a plurality of limiting grooves 2132a are arranged at the inner side of the first outer ring wall 2132, and the protrusions 2115 of the first bottom plate 211 are at least partially located in the limiting grooves 2132a of the first outer ring wall 2132. In the embodiment, the cooperation structure of the protrusions 2115 of the first bottom plate 211 and the limiting grooves 2132a of the first outer ring wall 2132 is beneficial to realize the positioning of the first bottom plate 211 and the first cover body 213. In other embodiments, the cooperation structure of the protrusions 2115 of the first bottom plate 211 and the limiting grooves 2132a of the first outer ring wall 2132 can also realize the mutual limiting of the first bottom plate 211 and the first cover body 213 in the circumferential direction, so that the connection structure of the first ligand 2 is stable and has high reliability.

[0145] Please refer to Figure 6 and Figure 3 , Figure 7 to Figure 9 is Figure 7 a cross-sectional view of the terminal accessory 10 shown in FIG. 10 along D-D.

[0146] In some embodiments, the first ligand 2 is installed at the top side of the shell 1 and can be connected with the base connecting member 12 of the shell 1. For example, the bottom of the first ligand 2 has a first accommodating space 23, and the first bottom plate 211 and the first outer ring wall 2132 jointly form the first accommodating space 23. The base connecting member 12 is at least partially located in the first accommodating space 23, and the first outer ring wall 2132 is arranged at the outer side of the base connecting member 12 and close to the base connecting member 12. The magnetic element 121 of the base connecting member 12 of the shell 1 and the first connecting member 212 of the first base 21 of the first ligand 2 form a magnetic attraction force, so that the first base 21 and the first ligand 2 are detachably fixed to the shell 1. The window hole 13 of the shell 1 exposes the first camera hole 214 of the first ligand 2 and the light inlet portion 221 of the light guide member 22.

[0147] In the embodiment, the first connecting member 212 of the first accessory 2 is connected to the base connecting member 12 of the shell 1 by magnetic attraction, and the first accessory 2 does not damage or slightly damages the shell 1 during disassembly and assembly. In other embodiments, the first connecting member 212 of the first accessory 2 can be connected to the base connecting member 12 of the shell 1 by snap connection or threaded connection, or other connection, which is not strictly limited in the embodiment.

[0148] Please refer to Figure 6 , the first accessory 2 can be provided with a first positioning mark 24, and the shell 1 is provided with a base positioning mark 14. By aligning the first positioning mark 24 with the base positioning mark 14 on the shell 1, the first accessory 2 can be accurately positioned in the circumferential direction of the shell 1, thereby improving the assembly accuracy of the terminal accessory 10. The positioning mark can be a pattern, a protrusion, a groove, or the like, which is not strictly limited in the embodiment.

[0149] Please refer to Figure 8 , Figure 7 is Figure 9 a cross-sectional view of the photographing system 100 along E-E.

[0150] In some embodiments, in the photographing system 100, when the terminal accessory 10 is fixed to the terminal 20, the window hole 13 on the shell 1 of the terminal accessory 10 exposes the camera 201 and the flash 202 of the terminal 20, the first camera hole 214 of the first accessory 2 of the terminal accessory 10 is directly opposite the camera 201, and the light inlet part 221 of the light guide member 22 of the first accessory 2 is directly opposite the flash 202.

[0151] The camera 201 can receive external light through the first camera hole 214, that is, it can be considered that the first camera hole 214 is directly opposite the camera 201. For example, the center line of the first camera hole 214 coincides with or slightly deviates from the optical axis of the camera 201, so that the camera 201 can receive more external light through the first camera hole 214, and the shooting quality is better.

[0152] The light emitted by the flash 202 of the terminal 20 can enter the light guide member 22 through the light inlet part 221, and be emitted from the light outlet part 222 of the light guide member 22, that is, it can be considered that the light inlet part 221 of the light guide member 22 is directly opposite the flash 202. For example, at least 50% of the light emitted by the flash 202 enters the light inlet part 221 of the light guide member 22, so as to improve the light intensity of the light emitted from the light outlet part 222 of the light guide member 22.

[0153] In some other embodiments, the light rays irradiated to the light inlet 221 of the light guide 22 can be light rays emitted by other components of the terminal 20, and the light inlet 221 of the light guide 22 can be arranged to face the components of the terminal 20, and the application does not make strict limitations in this regard.

[0154] Please refer to Figure 7 and Figure 10 , Figure 11 is Figure 10 the light path conduction diagram of the shooting system 100 shown in FIG. 10 when shooting the hidden camera. Figure 3 , Figure 11 is Figure 3 the light path conduction diagram of the shooting system 100 shown in FIG. 11 when shooting the hidden camera. Figure 6

[0155] In the embodiments of the application, the shooting system 100 can be used to detect the hidden camera 30, which can be but is not limited to a pinhole camera, a mobile phone camera, a night vision device, etc. In the detection process of the shooting system 100, the flash 202 forms outgoing light, the outgoing light enters the inside of the light guide 22 through the light inlet 221 of the light guide 22, and after multiple reflections in the inside of the light guide 22, the light is emitted by the light outlet 222 of the light guide 22. When the light emitted by the light outlet 222 irradiates the hidden camera 30, due to the “cat eye effect”, the high-reflectivity light-sensitive surface of the photoelectric sensor in the hidden camera 30 will reflect part of the light back along the original path, and the reflected light passes through the first camera hole 214 (including the light transmission hole 224 of the light guide 22) of the terminal accessory 10 and is collected by the camera 201. The terminal 20 analyzes the light collected by the camera 201 through a software algorithm, thereby identifying the position of the hidden camera 30 and realizing the detection of the hidden camera 30.

[0156] Please refer to Figure 11 , Figure 11 is a light path diagram when a traditional terminal shoots a hidden camera, Figure 12 is Figure 12 the light path diagram when the shooting system 100 shown in FIG. 10 shoots a hidden camera.

[0157] As shown in Figure 2 , when a traditional terminal detects a hidden camera through a flash 50, the light emitted by the flash 50 irradiates the hidden camera 30, and the light reflected by the hidden camera 30 is mainly concentrated around the flash 50. Figure 2 ​The middle solid line is the light emitted by the flash 50, and the dashed line is the light reflected back by the hidden camera 30. Since there is a certain distance between the flash 50 and the camera 40, most of the light reflected back by the hidden camera 30 is shot back around the flash 50, and only a small part is shot into the camera 40, so that the light reflected back by the hidden camera 30 is difficult to be captured by the camera 40 of the terminal, and the detection ability of the traditional terminal to the hidden camera 30 is low, and the detection accuracy is insufficient.

[0158] As shown in Figure 13 , Figure 13 and Figure 1 , in the embodiment of the present application, the positions of the light-in part 221 and the light-out part 222 of the light guide 22 and the first camera hole 214 of the terminal accessory 10 are set, so that the light guide 22 can guide the light emitted by the flash 202 to the position around the camera 201, and the light is emitted from the surrounding area of the camera 201. When the terminal 20 system detects the hidden camera, the light emitted by the flash 202 and reflected back by the hidden camera 30 is mainly concentrated in the area where the camera 201 is located and the surrounding area, so that the light reflected back by the hidden camera 30 is easily captured by the camera 201, increasing the receiving amount of the light reflected back by the hidden camera 30 by the camera 201, so that the shooting system 100 is more simple, fast and accurate in identifying the hidden camera 30. Therefore, the detection difficulty of the shooting system 100 to the hidden camera 30 in the embodiment of the present application is low, and the detection accuracy is high.

[0159] Please refer to Figure 14 and Figure 15 , Figure 14 is Figure 2 the interface diagram of the terminal 20 in the process of detecting the hidden camera. For example, the light emitted by the flash 202 of the terminal 20 is flickering light. At this time, although other reflective objects in the environment also produce reflection, which may interfere with the identification of the hidden camera 30 by the shooting system 100, but by using the principle of active and passive imaging, the terminal 20 can correct the shooting picture collected by the camera 201 after the camera 201 collects the shooting picture, so as to improve the identification accuracy. For example, when the flash 202 is on, the anti-hidden camera 30 in the environment will form a light spot 2041 in the shooting picture of the terminal 20, and when the flash 202 is off, the light spot 2041 in the shooting picture of the terminal 20 disappears. When the terminal 20 is slightly moved, the reflected light of the hidden camera 30 in the shooting picture will be concentrated in one position, and the reflected light of other objects will have obvious position change. The terminal 20 software compares multiple shooting images through algorithm, and can filter out most of the reflected light of the environment background and other noises, leaving and enhancing the reflected light spot 2041 of the hidden camera 30 in the picture, and prompting in the shooting picture of the terminal 20 interface. For example, as shown inFigure 1 As shown, the hidden camera 30 forms a light spot 2041 in the shooting screen of the terminal interface 204, and the terminal 20 provides a prompt through the prompt box 2042.

[0160] Please refer to it again. Figure 15 In some embodiments, the reflective film of the light guide 22 can cover the hole wall of the light-transmitting hole 224, thereby preventing the light in the light guide 22 from escaping from the hole wall of the light-transmitting hole 224 and interfering with the detection process of the shooting system 100 on the hidden camera 30, so as to improve the detection accuracy of the shooting system 100.

[0161] See also Figure 14 and Figure 2 In some embodiments of this application, the texture structure 2221 of the light-emitting portion 222 of the light guide 22 can be used to make the emission angle of the light beam emitted from the light-emitting portion 222 less than or equal to the field of view of the camera 201. In this embodiment, the texture structure 2221 enables the light in the light guide 22 to be emitted at a preset angle, confining this part of the light within the receiving field of view of the camera 201, making it easier for the light reflected back by the hidden camera 30 to be received by the camera 201, thereby improving the success rate of the shooting system 100 in recognizing the hidden camera 30.

[0162] In other embodiments, the positional relationship between the light-emitting portion 222 of the light guide 22 and the first camera hole 214 may differ from the aforementioned embodiments. For example, when the distance between the light-emitting portion 222 of the light guide 22 and the first camera hole 214 is less than the distance between the light-incident portion 221 and the first camera hole 214, the light-emitting portion 222 of the light guide 22 is positioned close to and on one side of the first camera hole 214, and does not surround the first camera hole 214. The light transmitted in the light guide 22 is emitted from one side of the first camera hole 214. In this case, since the light guide 22 can also guide the light emitted by the flash lamp 202 to be emitted around the first camera hole 214, the terminal accessory 10 can still improve the detection accuracy of the terminal 20 for the hidden camera 30.

[0163] In some other embodiments, when the light-emitting portion 222 of the light guide 22 is not arranged around the first camera hole 214, the light guide 22 may also not have a light-transmitting hole 224, and the light guide 22 may be arranged side by side with the first camera hole 214 rather than overlapping it. This application does not strictly limit the specific structure of the light guide 22 or its installation position in the first ligand 2.

[0172] In some embodiments, the second ligand 3 is mounted on the top side of the shell 1 and can be connected with the base connector 12 of the shell 1. For example, the second ligand 3 is provided with a second accommodating space 34 at the bottom, and the base connector 12 is at least partially located in the second accommodating space 34. The adapter ring can be wrapped around the outside of the base connector 12 and close to the base connector 12. The second connector 322 of the second base 32 of the second ligand 3 and the magnetic element 121 of the base connector 12 of the shell 1 form a magnetic attraction force, so that the second base 32 and the second ligand 3 are detachably fixed to the shell 1.

[0173] In the embodiment, the connection between the second connector 322 of the second ligand 3 and the base connector 12 of the shell 1 is magnetic attraction connection, and the second ligand 3 has no damage or little damage to the shell 1 during disassembly and assembly.

[0175] In some embodiments, the second base 32 of the terminal accessory 10 can be detachably fixed to the shell 1, and the through hole 326 of the second base 32 is opposite to the window hole 13 of the shell 1 and the camera 201 of the terminal 20. The adapter seat 33 of the second ligand 3 is used to mount the photographic filter 35, and the mounted photographic filter 35 covers the through hole 326 of the second base 32.

[0176] The through hole 326 can allow light to enter the window hole 13, that is, it can be considered that the through hole 326 is opposite to the window hole 13. The camera 201 can receive external light through the through hole 326, that is, it can be considered that the through hole 326 is opposite to the camera 201.

In addition, the threaded connection structure of the second adapter 3 and the photographic filter 35 is conducive to the installation and removal of various types and same sizes of photographic filters 35 on the second adapter 3.

[0179] Please refer to Figure 18 and Figure 20 , Figure 21 is Figure 20 the structural schematic diagram of the shooting system 100 in another use state.

[0180] In some embodiments of the present embodiment, the second adapter 3 can further include an adapter 36 connected to the adapter seat 33. The two ends of the adapter 36 can be provided with threaded structures, one end of which is provided with an external thread, and the other end is provided with an internal thread. The diameter of the external thread is different from the diameter of the internal thread. The external thread is installed in the mounting space 334 of the adapter seat 33 and is connected to the internal thread 333 of the adapter seat 33. The adapter 36 can be used to install a photographic filter, and the internal thread thereof can be used to connect the photographic filter. The diameter of the internal thread and / or the external thread of the adapter 36 can be 55mm, 52mm, 58mm, etc.

[0181] In the present embodiment, the second adapter 3 can install more photographic filters of different sizes through the adapter 36, so that the terminal system using the terminal accessory 10 can adapt to more types and more sizes of photographic filters, and the shooting experience is improved.

The shell 1 of the present embodiment includes all or part of the features of the shell 1 of the foregoing embodiment. The differences between the terminal accessory 10 of the present embodiment and the terminal accessory 10 of the foregoing embodiment will be mainly described below.

[0183] In some embodiments, the terminal accessory 10 comprises a housing 1 and a third accessory 4, which is detachably fixed to the housing 1. The connection between the housing 1 and the third accessory 4 is a detachable connection, so that the third accessory 4 is easy to connect and detach with the housing 1. In this embodiment, the connection between the housing 1 and the third accessory 4 is described by way of example of magnetic attraction. Exemplarily, the connection between the housing 1 and the third accessory 4 can be, but is not limited to, magnetic attraction, clamping connection or threaded connection, etc. In other embodiments, the third accessory 4 can also be fixed to the housing 1 by an undetachable connection.

[0184] Exemplarily, the third accessory 4 can be provided with a third positioning mark 41, and the housing 1 is provided with a basic positioning mark 14. By aligning the third positioning mark 41 with the basic positioning mark 14 on the housing 1, the third accessory 4 is accurately positioned in the circumferential direction of the housing 1, thereby improving the assembly accuracy of the terminal accessory 10. The positioning mark can be a pattern, a protrusion, a groove or the like, and the embodiments of the present application are not limited thereto.

[0185] Please refer to Figure 18 and Figure 23 , Figure 24A is Figure 23 the exploded view of the third accessory 4 shown in Figure 18 is Figure 24A the cross-sectional view of the diaphragm 43 along H-H shown in

[0186] In some embodiments, the third accessory 4 can comprise a third base 42 and a diaphragm 43. The third base 42 can comprise a third bottom plate 421, a third connecting piece 422 and a third cover 423. The third bottom plate 421 comprises a fourth recessed groove 4211, a fifth recessed groove 4212, a fourth through hole 4213 and a fifth through hole 4214.

[0188] The third cover body 423 comprises a third top plate 4231 and a third outer ring wall 4232 connected to the periphery of the third top plate 4231 and bent towards the bottom side of the third top plate 4231. The third top plate 4231 is provided with a sixth through hole 4231a and a seventh through hole 4231b arranged at intervals.

[0189] For example, the diaphragm 43 is used to converge light. The diaphragm 43 has an incident light side 431 and an exit light side 432 arranged oppositely. The incident light side 431 of the diaphragm 43 can be a planar structure, and the exit light side 432 of the diaphragm 43 can be a Fresnel structure 4321 with convex lens properties. In this embodiment, the diaphragm 43 has a smaller thickness by arranging the Fresnel structure 4321, which is beneficial to the thinness of the third body 4 and the terminal accessory 10.

[0190] Please refer to Figure 18 , Figure 23 is Figure 24B the cross-sectional structure schematic diagram of the third body 4 along I-I.

[0191] In some embodiments, in the third body 4, the third connecting piece 422 is installed in the fourth recessed groove 4211, and the third connecting piece 422 and the fourth recessed groove 4211 can be fixed by point gluing or back gluing (not shown in the figure). The diaphragm 43 can be installed in the fifth recessed groove 4212, the incident light side 431 of the diaphragm 43 can abut against the bottom wall of the fifth recessed groove 4212, the exit light side 432 of the diaphragm 43 is arranged away from the bottom wall of the fifth recessed groove 4212, and the diaphragm 43 can cover the fourth through hole 4213. The diaphragm 43 and the groove wall of the fifth recessed groove 4212 can be fixed by point gluing or back gluing (not shown in the figure).

[0192] The third cover body 423 is installed on the top side of the third bottom plate 421, the third top plate 4231 of the third cover body 423 is arranged oppositely to the third bottom plate 421, the third connecting piece 422 is located between the third top plate 4231 and the third bottom plate 421, and the third outer ring wall 4232 can be arranged around the third bottom plate 421. The sixth through hole 4231a of the third top plate 4231 is arranged corresponding to the fifth recessed groove 4212 of the third bottom plate 421, the diaphragm 43 can be partially located in the sixth through hole 4231a, and the exit light side 432 of the diaphragm 43 is exposed oppositely to the third top plate 4231. The seventh through hole 4231b of the third top plate 4231 communicates with the fifth through hole 4214 of the third bottom plate 421.

[0193] In the third ligand 4, the third base 42 has a third camera hole 424 and a flash hole 425, the third camera hole 424 includes the seventh through hole 4231b and the fifth through hole 4214, the flash hole 425 includes the fourth through hole 4213, the fifth recessed groove 4212 and the sixth through hole 4231a. At this time, the diaphragm 43 is fixed to the third base 42 and is arranged corresponding to the flash hole 425.

[0194] Please refer to Figure 24B and Figure 18 , Figure 25 to Figure 27 is Figure 25 the cross-sectional structure diagram of the structure shown in J-J.

[0195] In some embodiments, in the accessory, the third ligand 4 is mounted on the top side of the shell 1, and can be connected with the base connector 12 of the shell 1. Exemplarily, the bottom of the third ligand 4 has a third accommodating space 44, and the third bottom plate 421 and the third outer ring wall 4232 jointly form the third accommodating space 44. The base connector 12 is at least partially located in the third accommodating space 44, and the third outer ring wall 4232 surrounds the outside of the base connector 12 and is close to the base connector 12. Among them, the third connector 422 of the third base 42 of the third ligand 4 and the magnetic element 121 of the base connector 12 of the shell 1 form a magnetic attraction force, so that the third base 42 and the third ligand 4 are detachably fixed to the shell 1. Among them, the window hole 13 of the shell 1 exposes the third camera hole 424 and the flash hole 425 of the third ligand 4.

[0196] Please refer to Figure 26 and Figure 25 , Figure 27 is Figure 26 the cross-sectional structure diagram of the shooting system 100 along K-K, Figure 28 is Figure 29 the light path diagram of the shooting system 100 in some use states.

[0197] In some embodiments, the shell 1 of the terminal accessory 10 can be detachably sleeved on the terminal 20, the third camera hole 424 of the third ligand 4 of the terminal accessory 10 is directly opposite the camera 201 of the terminal 20, and the diaphragm 43 of the third ligand 4 is directly opposite the flash 202 of the terminal 20.

[0198] Among them, the camera 201 can accept external light through the third camera hole 424, that is, it can be considered that the third camera hole 424 is directly opposite the camera 201. Exemplarily, the center line of the third camera hole 424 coincides with or has a little deviation from the optical axis of the camera 201, so that the camera 201 can accept more external light through the third camera hole 424, and the shooting quality is better.

[0199] The light emitted by the flash 202 can irradiate the diaphragm 43 through the flash hole 425, that is, the diaphragm 43 of the third ligand 4 is considered to be opposite to the flash 202. For example, at least 50% of the light emitted by the flash 202 can irradiate the diaphragm 43, so that the shooting system 100 can form a light spot on the background with a better sunset lamp effect.

[0200] In one use state, as shown in FIG. 6, because the diaphragm 43 can converge light, when the light emitted by the flash 202 irradiates the background (for example, a wall) through the diaphragm 43, a light spot can be formed, so that the picture taken by the camera 201 including the light spot can have a sunset lamp effect. For example, the shooting system 100 can form a light spot on the background at a distance of 1.2m to 1.5m from the terminal. Figure 28

[0201] For example, the focal length of the diaphragm 43 can be in the range of 4mm to 7mm, so that the shooting system 100 can form a light spot on the background at a distance of 1.2m to 1.5m with a better sunset lamp effect. For example, the pitch of the Fresnel structure 4321 of the diaphragm 43 is in the range of 0.05mm to 0.3mm, and the tooth depth is in the range of 0.05mm to 0.3mm. Wherein, the pitch and tooth depth of each tooth in the Fresnel structure 4321 can be fine-tuned according to the optical effect, and the specific size is not strictly limited in the embodiments of the present application.

[0202] In some embodiments of the present application, the accessory can include a shell 1, a first ligand 2 and a second ligand 3. The structures of the shell 1, the first ligand 2 and the second ligand 3 can refer to the related description of the foregoing embodiments. Wherein, the first ligand 2 and the second ligand 3 can be detachably fixed to the shell 1. In this embodiment, because the terminal accessory 10 adopts a multi-ligand structure, the shooting system 100 can improve the detection accuracy of the stolen camera 30 by installing the terminal accessory 10 with the first ligand 2, and can also meet the diversified shooting needs by installing the terminal accessory 10 with the second ligand 3, thereby improving the diversity of the shooting system 100 and the user experience.

[0203] For example, the shell 1 includes a basic connector 12, the first base 21 of the first ligand 2 includes a first connector 212, and the second base 32 of the second ligand 3 includes a second connector 322. The first connector 212 and the second connector 322 can be detachably connected to the basic connector 12 by the same connection mode. In this embodiment, the first ligand 2 and the second ligand 3 are fixed to the shell 1 by the same connection mode, which can simplify the structure of the terminal accessory 10 and reduce the cost.

[0211] Please refer to Figure 27 andFigure 30 , Figure 31 is Figure 31 is an exploded structural schematic view of the housing 1 of the terminal accessory 10, Figure 26 is Figure 32 is a sectional structural schematic view of the housing 1 along L-L.

[0212] In some embodiments, the housing 1 comprises a housing base 11 and a base connector 12, the housing base 11 has a through hole 114. The base connector 12 comprises a bottom wall 125 and a side wall 126, the middle part of the bottom wall 125 has the mounting hole 124, the side wall 126 is connected to the periphery of the bottom wall 125, the side wall 126 is bent towards the top of the bottom wall 125 relative to the bottom wall 125, and the side wall 126 and the bottom wall 125 jointly enclose the mounting groove 16. The base connector 12 is installed in the through hole 114 of the housing base 11, and the side wall 126 of the base connector 12 is fixedly connected to the hole wall of the through hole 114 of the housing base 11.

[0213] In other embodiments, the housing base 11, the base connector 12 and the connection relationship therebetween can also be designed in other manners, and the embodiments of the present application do not make strict limitations in this regard. For example, in other embodiments, the base connector 12 can also be embedded in the interior of the housing base 11.

[0214] Please refer to Figure 33 and Figure 32 , Figure 25 is Figure 33 is a sectional structural schematic view of the first accessory 2 along M-M, Figure 25 is Figure 33 is a sectional structural schematic view of the terminal accessory 10 along N-N.

[0215] In some embodiments, the bottom of the first accessory 2 is provided with a clamping protrusion 25. For example, the clamping protrusion 25 can be protruded from the bottom of the periphery of the first bottom plate 211. In the terminal accessory 10, the clamping protrusion 25 of the first accessory 2 is at least partially located in the mounting groove 16 of the housing 1, and through the cooperation of the clamping protrusion 25 and the mounting groove 16, the alignment and limiting of the first accessory 2 and the housing base 11 can be realized. In other embodiments, the housing 1 can also not be provided with the mounting groove 16, and the first accessory 2 can be at least partially located in the mounting hole 124 or on the top side of the housing 1.

[0216] For example, the first accessory 2 can be provided with a magnet, the base connector 12 can comprise a magnetic element 121 and a magnetic shielding sheet 122 (not shown in the figure), and the first accessory 2 and the base connector 12 are fixed through magnetic attraction.

[0217] It can be understood that, Figure 34 The connecting structure of the shell 1 and the first ligand 2 in the corresponding embodiment can also be applied to the foregoing Figure 35 The connecting structure of the shell 1 and the first ligand 2, the second ligand 3, and / or the third ligand 4 in the corresponding embodiment.

[0218] In the foregoing Figure 34 In the corresponding embodiment, the terminal accessory 10 is mainly taken as a protective shell for example, and the implementation mode of the terminal accessory 10 being a camera accessory is exemplarily described below.

[0219] Please refer to Figure 35 and Figure 34 , Figure 36 is a structural schematic diagram of the photographing system 100 in another embodiment, Figure 37 is Figure 36 is a partially exploded structural schematic diagram of the photographing system 100 shown in Figure 35 is Figure 37 is a cross-sectional structural schematic diagram of the terminal accessory 10 along O-O shown in

[0220] The main difference between the terminal accessory 10 of the embodiment and the foregoing embodiments is that the terminal accessory 10 of the embodiment has the same or similar structure as the first ligand 2, the second ligand 3, or the third ligand 4 in the foregoing embodiments. The terminal accessory 10 of the embodiment does not include the shell 1, and the terminal accessory 10 of the embodiment is directly fixed to the camera 201 region of the terminal 20.

[0221] Exemplarily, the photographing system 100 includes the terminal 20 and the terminal accessory 10, and the terminal accessory 10 has the same or similar structure as the first ligand 2 in the foregoing embodiments. For example, the terminal 20 includes the camera 201 and the flash 202, and the terminal accessory 10 includes the first base 21 and the light guide member 22. The first base 21 has the first camera hole 214, and the light guide member 22 is fixed to the first base 21. The light guide member 22 includes the light-in portion 221 and the light-out portion 222, the light-in portion 221 and the light-out portion 222 are oppositely arranged, and both are exposed relative to the first base 21. The distance between the light-out portion 222 and the first camera hole 214 is less than the distance between the light-in portion 221 and the first camera hole 214. The terminal accessory 10 is detachably fixed to the terminal 20, the first camera hole 214 is opposite to the camera 201, and the light-in portion 221 is opposite to the flash 202. In the embodiment, other descriptions of the terminal accessory 10 can refer to the related content of the first ligand 2 in the foregoing embodiments.

[0222] In the embodiment of the present application, the light guide 22 can guide the light emitted by the flash 202 to the position around the camera 201 and be emitted by the area around the camera 201, by setting the positions of the light inlet 221, the light outlet 222 and the first camera hole 214 of the light guide 22 of the terminal accessory 10. When the terminal system detects the hidden camera 30, the light emitted by the flash 202 and reflected back by the hidden camera 30 is mainly concentrated in the area where the camera 201 is located and the surrounding area, so that the light reflected back by the hidden camera 30 is easily captured by the camera 201, which increases the amount of light reflected back by the hidden camera 30 received by the camera 201, and makes the shooting system 100 more simple, fast and accurate in identifying the hidden camera 30. Therefore, the shooting system 100 in the embodiment of the present application has low detection difficulty and high detection accuracy for the hidden camera 30.

[0223] In some embodiments, the terminal accessory 10 further comprises a fixing structure fixed to the first base 21, and the fixing structure is used to fix the terminal accessory 10 to the terminal 20. For example, the fixing structure can comprise a magnet, which is used to be magnetically connected with a magnetic element 121 (not shown in the figure) of the terminal 20, so as to fix the terminal accessory 10 to the terminal 20. In other embodiments, the fixing structure can also comprise a reusable adhesive, which can be located at the bottom of the terminal accessory 10 and used to bond the terminal 20, and can be removed when disassembly is needed and can bond the terminal 20 again in the next assembly process. In other embodiments, the fixing structure can also be a threaded connection structure or a clamping structure, etc.

[0224] In some embodiments, as shown in Figure 35 Figure 38 Figure 39 Figure 38 Figure 35 Figure 39 Figure 34 Figure 34 to Figure 39 Figure 1 to Figure 33 Figure 1 to Figure 39 Figure 40 Figure 41 Figure 40 Figure 41 Figure 40 Figure 42 Figure 41 Figure 42 The bottom of the terminal accessory 10 can be provided with a recessed space 26, which is used to avoid the camera 201 or the camera decoration of the terminal 20 when the terminal accessory 10 is fixed to the terminal 20, so as to avoid abrasion to the camera 201 or the camera decoration, and improve the reliability and service life of the shooting system 100.

[0225] It can be understood that in other embodiments, the terminal accessory 10 with the same or similar structure as the second ligand 3 or the third ligand 4 in the foregoing embodiments can also be directly fixed to the terminal 20, and can also comprise a fixing structure for fixing to the terminal 20, which is not strictly limited in the embodiment of the present application.

[0226] The above examples are only used to illustrate the technical solutions of the present application, but not to limit the same; although the present application has been described in detail with reference to the foregoing examples, it should be understood by those of ordinary skill in the art that the technical solutions recorded in the foregoing examples can be modified, or some technical features thereof can be replaced by equivalent ones; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
