DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] The various specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, various possible combinations of the specific technical features in the present invention will not be described separately.

[0030] In the embodiments of the present invention, the field of view refers to the area of ​​the object that can be seen on the screen of the mobile terminal; the object side refers to the side close to the object; and the image side refers to the side where the image sensor forms an image.

[0031] The mobile terminal 1 provided in the embodiment of the present invention may be a mobile phone, a laptop computer, a tablet computer, or the like. Figure 1As shown, the mobile terminal 1 is illustrated as a mobile phone, and the type of the mobile terminal 1 is not limited.

[0032] like Figure 1 and Figure 2 As shown, the mobile terminal 1 provided in the embodiment of the present invention includes a housing 11, a lens 12, a camera assembly 13 and a driving member 14. The housing 11 has a housing cavity inside for accommodating some necessary parts such as a circuit board 15 and a battery. The lens 12 is fixedly connected to the housing 11, and the camera assembly 13 is arranged in the housing 11, including a plurality of lenses 131 that can be superimposed with the lens 12 to photograph the field of view of the mobile terminal 1. Specifically, the types of the lenses 131 are different, and they have different photographing functions, such as wide-angle macro lenses 131 or telephoto lenses 131. The lens 12 is usually a lens and has good optical properties, which can change the object distance of the lens 131, and finally change the image formed. For example, after the lens 131 is superimposed with the lens 12, the focusing distance when the picture is taken can be changed, so that images with different magnifications can be obtained, and different photographing experiences can be obtained. In order to select different types of lenses 131 and lens 12 to be superimposed according to shooting requirements, a driving member 14 is connected to the camera assembly 13 to drive the lenses 131 to rotate so that each lens 131 can be superimposed with the lens 12. Therefore, according to the current shooting requirements, each lens 131 is driven to rotate by the driving member 14, and the corresponding lens 131 can be superimposed with the lens 12 as required to meet the current shooting requirements. For example, when it is necessary to perform close-up microscopic shooting of the object to be photographed, the wide-angle macro lens 131 is rotated by the driving member 14 to be superimposed with the lens 12. Under the common optical performance of the lens 12 and the wide-angle macro lens 131, the object to be photographed can be photographed at close range to obtain an image with a large magnification.

[0033] The mobile terminal 1 provided in the embodiment of the present invention has a lens 12 disposed on the housing 11, and a lens 131 capable of realizing different shooting functions is disposed in the housing 11. By making the lens 12 overlap with different lenses 131 for shooting, different shooting functions can be realized, and the lens 131 can be an existing lens 131 such as a standard lens 131, a wide-angle lens 131, and a telephoto lens 131. Therefore, by adopting this arrangement, it is only necessary to arrange the lens 12 on the housing 11, and there is no need to re-arrange the structure of the lens 131, thereby saving the cost required for re-arranging the lens 131, and further reducing the production cost of the mobile terminal 1.

[0034] In the above, the meaning of superposition is that the lens 12 can be superimposed with the lens 131 in the object side direction of the lens 131, and together with the lens 131, a new camera component is formed, and a specific shooting function is realized by changing the object distance from the object to the lens 131 and the optical parameters of the lens 131, and processing the incident light. After superposition, the distance between the lens 12 and the lens 131 can be in contact with each other, or can be separated by a certain distance, and the distance satisfies effective focus during shooting.

[0035] like Figure 2 and Figure 3 As shown, in the embodiment of the present invention, the lens 12 is fixed on the housing 11. Therefore, in order to realize the fixed installation of the lens 12, a mounting hole 111 is provided on the housing 11, and the lens 12 is fixed in the mounting hole 111. The installed lens 12 is fixed on the housing 11, and the position will not change. The superimposed shooting with each lens 131 is realized by the rotation of each lens 131 located inside the housing 11. At the same time, a through hole 112 is also provided on the housing 11, and the through hole 112 can be superimposed with the lens 131 for shooting. That is, the lens 12 is not installed in the through hole 112. The through hole 112 serves as a avoidance structure for the lens 131 and does not block the framing of the lens 131. The camera function that can be realized by the lens 131 is realized by the functional characteristics of the lens 131 itself. In this way, when there is no need to superimpose shooting with the lens 12, the lens 131 can directly shoot through the through hole 112, so that the mobile terminal 1 still has the function of conventional shooting. Of course, it is understandable that a lens can also be provided in the through hole 112 to prevent external dust and impurities from entering the housing 11 through the through hole 112. Moreover, the lens does not affect the light in the field of view from entering the lens 131, nor does it change the path of the incoming light.

[0036] In some embodiments, a plurality of mounting holes 111 may be provided on the housing 11, and lenses 12 with different optical properties may be provided in each mounting hole 111, so that they can be combined with different lenses 131 to achieve different shooting functions. Alternatively, a plurality of lenses 12 may be provided in each mounting hole 111, and the object distance of the lens 131 may be changed by the plurality of lenses 12 to achieve different shooting effects. A plurality refers to two or more.

[0037] like Figure 3 and Figure 4As shown, the camera assembly 13 also includes a PCB board 132, an image sensor 133 and a fixture 134. The image sensor 133 is arranged on the image side of the lens 131, and is used to sense the imaging signal of the lens 131. Specifically, CMOS is usually used as the image sensor 133 in mobile phones. The CMOS image sensor 133 integrates a DSP (digital processing chip) and appears to be a single component in appearance. The image sensor 133 (CMOS image sensor 133 integrated with DSP) is fixed on the PCB board 132, and the fixture 134 is arranged on the outside of the image sensor 133 (i.e., the side close to the object being photographed) and is connected to the PCB board 132. The fixture 134 is provided with a cavity for accommodating the lens 131, and the lens 131 is opposite to the image sensor 133. During the photographing process, the light of the photographed object first passes through the lens 131 and then reaches the image sensor 133. The photons in the light hit the image sensor 133 to generate movable charges. This is the internal photoelectric effect. The movable charges are collected to form an electrical signal, which is converted into a digital signal through the A / D converter. The digital signal is sent to the DSP (Digital Signal Processor) for processing and finally transmitted to the screen of the mobile terminal 11 to form a display image, thus realizing the photographing of the photographed object. Specifically, the structure of the DSP includes an ISP (Image Signal Processor) and a JPEG encoder, among which the ISP is the key to determining the smoothness of the image.

[0038] It is understandable that for CMOS, DSP can be integrated into CMOS. CMOS has the advantages of high integration, low power consumption, and low cost, and is more suitable for mobile phones with limited installation space.

[0039] In some embodiments, the lens 12 is superimposed with the lens 131 to achieve close-up macro photography. Macro photography refers to the use of the optical capability of the lens 131. Under the premise of ensuring clear imaging of the object, the mobile terminal 11 can shoot with a larger optical magnification when it is close to the object. The optical magnification refers to the ratio between the imaging height of the image sensor 133 and the height of the object.

[0040] It should be noted that the magnification rate felt by the user = optical magnification rate * screen magnification rate * digital magnification rate, where the optical magnification rate refers to the ratio of the height of the image on the image sensor 133 to the height of the object being photographed, the screen magnification rate refers to the ratio of the screen size to the size of the image sensor 133, and the digital magnification rate is the ratio of the size of the same part on the screen after the user artificially magnifies the part on the screen to the size of the same part on the screen before the magnification. Specifically, for example, the principle of image magnification felt by the user after shooting is as follows: Figure 5 As shown, the light reflected from the object 172 reaches the image sensor 133 after passing through the lens 131, and then generates an electrical signal. After passing through the analog-to-digital conversion device, the electrical signal is converted into a digital signal. After being processed by the DSP, it is transmitted to the screen 18 of the terminal device to form an image, and the user can magnify a part of the image as needed on the screen 18. At this time, the image displayed on the screen 18 is the screen magnified image 19.

[0041] Specifically, according to the basic optical imaging principle, tan(FOV / 2) = imaging height / focal length = object height / object distance, and the optical magnification = imaging height / object height = focal length / object distance. Among them, FOV is the field of view angle, which refers to the angle formed by two sides of the maximum range that the measured or photographed object can pass through the center of the lens 131 with the center of the lens 131 of the optical instrument as the vertex in the optical instrument. FOV is usually used to measure the field of view range of the lens 131. For example, the viewing angle of a conventional standard lens 131 is about 45 degrees, and the viewing angle of a wide-angle lens 131 is above 60 degrees. According to the above formula for calculating the optical magnification, to increase the optical magnification, it can be achieved by reducing the object distance or increasing the focal length, that is, on the premise of ensuring clear imaging, the lens 131 is as close as possible to the object and the focal length of the lens 131 is increased.

[0042] According to the Gaussian imaging formula, 1 / f = 1 / u + 1 / v. Where f is the focal length; u is the object distance; v is the image distance; when u > 2f, a reduced and inverted image is formed on the image sensor 133; when u = 2f, v = f, that is, the focal length is equal to the image distance, and an equal-sized and inverted image is formed on the image sensor 133; f < u < 2f, an enlarged and inverted image is formed on the image sensor 133; when u = f, no image is formed; when u < f, a virtual image is formed and cannot be imaged on the image sensor 133113. Therefore, when the focal length f remains unchanged, v and u show an opposite change trend. When u increases, v decreases; when u decreases, v increases. Since macro shooting is a shooting method of taking a close-up shot to obtain an enlarged image of the object, that is, an enlarged real image is formed on the image sensor 133. Therefore, during close-up macro shooting, the object distance u is relatively small. Therefore, in order to meet the focusing requirement, the focal length of the lens 131 needs to be smaller to ensure that f < u < 2f, and the image distance and the object distance satisfy the above Gaussian imaging formula.

[0043] In the embodiment of the present invention, at least one lens 131 is a wide-angle macro lens, which means that the focal length of the lens is short, the viewing angle is large, and a large area of ​​scenery can be captured within a short shooting distance range. By superimposing the wide-angle macro lens with the lens 12, an ultra-macro lens can be formed, that is, a lens that can clearly perform large optical magnification shooting when the object distance is very small. In the embodiment of the present application, macro photography and microscopic photography can be achieved under the superposition of the lens 131 and the lens 12. Specifically, the effective focal length f of the wide-angle macro lens is 1.335mm, the field of view (FOV) at the maximum image height is 77.6 degrees, the aperture value (f-number) is 2.8, and the minimum working distance is 3mm, wherein the working distance refers to the distance from the object to the vertex (center) of the first surface of the lens 12 (the surface closest to the object), that is, the lens 131 can at least focus on the object with an object distance of about 3mm, and can achieve clear shooting of the image. Of course, depending on different shooting requirements, the lens 131 can also be used to achieve clear shooting of objects with a working distance of more than 3 mm.

[0044] like Figure 2 As shown, the camera assembly 13 also includes a rotating bracket 135. The rotating bracket 135 is used to provide support for each lens 131, and each lens 131 is installed on the rotating bracket 135, and the driving member 14 is connected to the rotating bracket 135. In this way, the driving member 14 provides a driving force to drive the rotating bracket 135 to rotate, and the rotating bracket 135 drives each lens 131 to rotate, so as to select the required lens 131 and the lens 12 to be superimposed to meet the shooting requirements. Specifically, it is preferred to set the rotating bracket 135 as a disc, the driving shaft of the driving member 14 is connected to the center position of the rotating bracket 135, and each lens 131 is evenly spaced on the rotating bracket 135 to ensure that the rotating bracket 135 can rotate smoothly. At the same time, the rotating bracket 135 can be provided with a fixing hole to realize the fixing of each lens 131, ensuring the stability and reliability of each lens 131 after installation. The shape of the fixing hole matches the shape of the lens 131 to be installed, so that the lens 131 can be effectively installed.

[0045] In one possible implementation, Figure 6 and Figure 7As shown, the image sensor 133 is fixed on the rotating bracket 135. After the image sensor 133 is fixed on the rotating bracket 135, it is located on the image side of the lens 131, and is used to convert the optical image captured by the lens 131 into a digital signal, and send the digital signal to the digital signal processing chip, which performs optimization processing to obtain the corresponding image. In this way, the image sensor 133 set on the image side of each lens 131 is determined. That is, the image sensor 133 corresponding to each lens 131 can rotate synchronously and cannot be changed during the rotation process.

[0046] In one possible embodiment, Figure 2 and Figure 8 As shown, the image sensor 133 is fixed on the circuit board 15 in the housing 11. Usually, a circuit board 15 is arranged inside the housing 11, and the image sensor 133 is fixed on the circuit board 15, and is spaced apart from the lens 131. The spacing distance is based on the premise that the image sensor 133 can effectively sense the optical image captured by the lens 131, so as to accurately convert the optical image into a digital signal. With this arrangement, the image sensor 133 arranged on the image side of each lens 131 will not rotate with the lens 131 after the lens 131 rotates. That is, when the lens 131 rotates and adjusts, the image sensor 133 corresponding to the lens 131 changes.

[0047] like Figure 2 As shown, in the embodiment of the present invention, the image sensor 133 (refer to Figure 3 ) includes a first image sensor 1331 and a second image sensor 1332. The first image sensor 1331 is used to image the light after passing through the superimposed lens 12 and the lens 131; the second image sensor 1332 is arranged at a distance from the first image sensor 1331, and is used to image the light after passing through the lens 131 without the lens 12 superimposed. In this way, the image side of the lens 131 superimposed with the lens 12 and the lens 131 not superimposed with the lens 12 always has the image sensor 133. Therefore, not only can the shooting after the lens 131 is superimposed with the lens 12, or the lens 131 is not superimposed with the lens 12, but the lens 131 directly performs conventional shooting alone, but also the image combination formed by the superimposed shooting of one of the lenses 131 and the lens 12 and the conventional shooting of the other lens 131 alone can be realized, so as to realize different shooting functions and further improve the shooting experience.

[0048] like Figure 7 and Figure 8As shown, the camera assembly 13 also includes a rotating shaft 136. One end of the rotating shaft 136 is connected to the rotating bracket 135, and the other end is connected to the driving member 14. Driven by the driving member 14, the rotating bracket 135 is rotated around the axis of the rotating shaft 136 to adjust different lenses 131 and lenses 12 as needed to achieve stacking. Specifically, the rotating shaft 136 is adjacent to the lens 131 and has a certain distance, so that the rotation of the rotating bracket 135 can be achieved without interfering with the lens 131. It should be noted that there can be many ways to connect the rotating shaft 136 to the rotating bracket 135, such as snap-on, threaded connection, etc. The connection between the rotating shaft 136 and the driving member 14 can be connected through a sleeve, or a connecting hole is provided on the rotating shaft 136, and the driving shaft of the driving member 14 is inserted into the connecting hole to achieve a fixed connection.

[0049] Specifically, in order to achieve the smooth rotation of the rotating bracket 135, the rotating shaft 136 is vertically connected to the rotating bracket 135, and the center of the rotating bracket 135 is located on the axis of the rotating shaft 136. In this way, after the rotating bracket 135 is connected to the rotating shaft 136, the rotating shaft 136 is located at the center of the rotating bracket 135, and the rotating bracket 135 can maintain balance. In the process of rotating with the rotating shaft 136 as the support, it can remain stable and not tilt, and achieve smooth and smooth rotation. Specifically, after the rotating shaft 136 is connected to the rotating bracket 135, the axis of the rotating shaft 136 is aligned with the optical axis of each lens 131 (refer to Figure 7 ) are kept parallel.

[0050] In some possible implementation schemes, the type of lens 12 can be selected according to actual design requirements, and the lens 12 can be set as a convex lens or a concave lens. That is, the lens 12 installed on the housing 11 can be a convex lens or a concave lens, or when multiple lenses 12 are simultaneously arranged on the housing 11, each lens 12 can be set as a convex lens and a concave lens respectively. In a specific application, when the lens 12 is set as a convex lens, the focal length of the lens group formed after being matched with each lens 131 becomes longer, and after each lens 131 is rotated and switched to the bottom of the lens 12 to achieve superposition, a longer focal length effect can be obtained, such as superimposing with the telephoto lens 131 to obtain a longer focal length and a larger zoom ratio. When the lens 12 is set as a concave lens, the focal length of the lens group formed after being matched with each lens 131 becomes shorter, and after each lens 131 is rotated and switched to the bottom of the lens 12 to achieve superposition, a shorter focal length effect can be obtained, such as a shorter focal length when superimposed with the wide-angle macro lens 131, and a better experience effect can be obtained.

[0051] The focal length of the lens 131 is related to the optical performance of the lens 131 itself. A telephoto lens 131 can be used to increase the focal length of the lens 131 to improve the optical magnification. Specifically, the lens 131 itself also has its own magnification; the optical magnification of the optical instrument or electronic device is related to the magnification of the lens 131 itself. The magnification of the lens 131 and the lens 12 is related to the magnification of the lenses that compose them. The magnification of the lens 12 refers to the ratio of the image size of the object on the focal plane through the lens to the actual size of the object. In addition, the lens 12 may include one or more lenses. The different magnifications of each lens 12 means that in the case of the same image sensor 133, the optical magnifications corresponding to different lenses 12 are different.

[0052] In some possible implementation schemes, the lens 12 can also be set as an external component. When superimposed shooting is required through the lens 12, the component can be connected to the corresponding camera by bonding or vacuum adsorption, and the corresponding shooting function can be obtained after superimposed with the camera.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
