TECHNICAL FIELD
[0001] The present application belongs to the field of micro image equipment, and particularly relates to an embedded micro image acquisition terminal. BACKGROUND
[0002] At present, micro photography is one of the specialties of digital cameras, and common scenes can be shot into dramatic scenes by micro photography, and micro photography is particularly good at showing small things such as flowers, birds, fish and insects, and can fully show details and observe the organization or texture structure of objects, such as wood section texture structure, identification of gemstones and antiques.
[0003] However, when taking photos on site, for example, customs departments need at least two workers, one for taking photos and the other for compensating exposure from one side, and therefore, the following defects exist:
[0004] 1) Since focusing is performed manually, it is difficult to ensure that the focusing distance is the same each time, so that the photos taken have different standards and cannot accurately obtain the texture structure information of the photographed object;
[0005] 2) During the shooting process, the photographer inevitably shakes the lens, so it is also difficult to stably obtain satisfactory photos;
[0006] 3) When compensating exposure, the angle of light source irradiation is different, and the external light interference also affects the exposure effect, and the lateral light causes the shadow of the photographed object, thereby affecting the shooting effect;
[0007] 4) It is expensive and inconvenient to carry. SUMMARY
[0008] The technical problem to be solved by the present application is to overcome the deficiencies of the prior art and provide an improved embedded micro image acquisition terminal.

[0011] Preferably, the lens is arranged in parallel with the front end surface of the compression ring. In this way, it can be ensured that the structure of the surface of the sample to be detected is magnified at the same focal length.

[0013] Preferably, the first cavity is cylindrical, the second cavity is frustoconical and gradually increases in diameter from the first cavity, and the lens is positioned at the communication between the first cavity and the second cavity.
[0014] According to another specific embodiment and a preferred aspect of the present application, the lamp is mounted in the second cavity, and the compression ring abuts against the lamp.
[0015] Preferably, the diameter of the annular inner cavity of the lamp is greater than the outer diameter of the lens, and the center line of the lamp, the center line of the lens, and the center line of the compression ring are arranged in line.
[0016] Specifically, the lamp comprises an annular lamp strip, a plurality of light bodies arranged on the annular lamp strip, and a power supply and a control switch.

[0019] In addition, the compression ring is detachably connected with the second part, and the inner cavity of the compression ring is in a straight cylinder shape or a frustoconical shape with a free diameter gradually increasing forward.

[0034] As Figure 1 shown, the embedded macro image acquisition terminal of the embodiment comprises a macro lens 1 and a lamp 2 for compensating exposure.
[0035] As Figure 2 shown, the macro lens 1 comprises a lens seat 10 and a lens 11, wherein the lens seat 10 comprises a seat body 100, a press ring 101 detachably arranged at the front end of the seat body 100, and a lens outer connecting part 102 arranged at the rear end of the seat body 100.
[0036] In this case, the press ring 101 is annular, and the inner cavity of the seat body 100, the inner cavity of the press ring 101, and the surface of the sample to be detected form a closed image acquisition area.
[0037] The seat body 100 comprises a first part 100a and a second part 100b, which are internally formed with a first cavity q1 and a second cavity q2, respectively.
[0038] Specifically, the first cavity q1 is cylindrical, and the second cavity q2 is frustoconical with a gradually increasing diameter from the first cavity to the front. The lens 11 is installed at the communication between the first cavity q1 and the second cavity q2.
[0039] The lens 11 is arranged in parallel with the front end surface of the press ring 101. In this way, the structure magnified picture of the surface of the sample to be detected can be obtained at the same focal length.
[0040] As Figure 3 shown, the press ring 101 is detachably connected with the second part 100b, and the inner cavity of the press ring 101 is straight or frustoconical with a gradually increasing inner diameter from the front. The selection is made according to the object to be photographed. For example, for objects, a common straight cylinder can be used. Small objects are located in the straight cylinder area and close to the lens, so that the magnified picture of the clear object structure can be easily obtained. Once the object to be photographed is large in size, such as the texture structure of a conventional wood section, the frustoconical shape is used, which can not only expand the image acquisition area but also facilitate focusing.
[0041] The lens outer connecting part 102 is an external thread arranged at the outer periphery of the first part 100a.
[0042] The lamp 2 is annular, and the lamp 2 is embedded in the second cavity q2, and the press ring 101 abuts against the lamp 2.
[0043] The diameter of the annular inner cavity of the lamp 2 is greater than the outer diameter of the lens 11, and the center line of the lamp 2, the center line of the lens 11, and the center line of the press ring 101 are arranged in coincidence.
[0044] As Figure 4 shown, the lamp 2 comprises an annular lamp strip 20, a plurality of light bodies 21 arranged on the annular lamp strip 20, and a power supply and a control switch.
[0045] Specifically, the light body 21 is a conventional bulb, such as an LED lamp. The lamp 2 is provided with a fitting gap k on one side of the second cavity q2, and further comprises an external power connector 22 extending outward from one side of the annular lamp strip 20, wherein the external power connector 21 is embedded from the fitting gap k, the annular lamp strip 20 is arranged in abutment with the wall surface of the second cavity q2 and is spaced apart from the lens. Through the arrangement of the external power connector, on the one hand, the positioning of the annular lamp strip can be realized to prevent displacement; on the other hand, through the transmission line, the power supply of the mobile phone can be communicated with the power supply of the lamp, so that the mobile phone directly supplies power.
[0046] In addition, the power supply is a conventional lithium battery, which can be charged. Once the transmission line is forgotten, the lithium battery can supply power to the light body 21.
[0047] Therefore, the embodiment has the following advantages:
[0048] (1) The annular light around the camera can provide precise annular light supplement centered on the photographed object (there is no annular light supplement lamp centered on the camera of the mobile phone at present), which can greatly eliminate the shadow of the photographed object compared with other lateral light;
[0049] (2) Cooperating with various fixing clamps, the light supplement camera can be flexibly replaced for multi-camera mobile phones;
[0050] (3) The size is very small, which can meet the high flexibility requirement of macro photography, and has high portability;
[0051] (4) The power supply is convenient, and the mobile phone can directly supply power;
[0052] (5) After the macro lens and the shooting device are combined, not only the microstructure of the object surface can be photographed, but also the small object (such as insects, jewelry, flowers, etc.) can be photographed, and the light supplement in the image acquisition area by the lamp can not only reduce the focusing distance under the macro lens, but also provide stable and shadow-free light supplement conditions for the lens during shooting, so that the effect of the obtained photo (such as high definition) is good, and the operation can be completed by one person, which is very convenient.
[0053] The above has described the present application in detail, the purpose of which is to enable persons skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application, and any equivalent changes or modifications made according to the spirit and principle of the present application should be covered within the protection scope of the present application.
