[0051] Figure 22 is an exploded perspective view of a camera module according to a first embodiment of the present application, Figure 23 is Figure 24 is an example of a side sectional view of a first lens group and a second lens group of the camera module of Figures 22 to 24 is an example of a side sectional view illustrating Figure 25 is an example of a side sectional view of an example of driving of the first lens group and the second lens group in the camera module of Figure 25 is an example of driving of Figure 25 is an example of driving of the camera module of Figure 26 is a view illustrating an example of driving of another example of the driving unit according to Figure 25

[0052] Referring to Figure 27 ​The camera module can include a first holder 11 having a plurality of first lens groups 212 and 232, a second holder 21 having a plurality of second lens groups 214 and 234, and an image sensor module 30 that converts light incident through the first lens groups 212 and 232 and the second lens groups 214 and 234 into an electrical signal. The camera module can include a module having a plurality of lens modules 210 and 230 and a plurality of image sensors 35 and 35A. The image sensor module 30 can include a printed circuit board 31 provided with a plurality of image sensors 35 and 35A.

[0053] A housing (not shown) can be further provided outside the first holder 11 and the second holder 21. Such a housing can include a space capable of covering the movement of the first holder 11 in the optical axis direction and a space capable of covering the movement of the second holder 21 in the horizontal direction. The first holder 11 can be a first lens barrel for supporting and housing a plurality of first lens groups 212 and 232. The second holder 21 can be a second lens barrel for supporting and housing a plurality of second lens groups 214 and 234. In the driving or photographing mode, as shown in FIG. 1A, the first holder 11 is disposed on the second holder 21, and thus the first holder 11 and the second holder 21 can overlap in the vertical direction. In the non-driving or non-photographing mode, as shown in FIG. 1B, the first holder 11 is disposed on the side surface of the second holder 21, and thus the first holder 11 and the second holder 21 can overlap in the horizontal direction. Figure 26 Figure 28

[0054] ​​The plurality of lens modules 210 and 230 can include the first lens module 210 and the second lens module 230 aligned along different optical axes and spaced apart in the first direction X. Here, in the driving mode, the first lens module 210 can include the 1-1 lens group 212 and the 2-1 lens group 214 aligned with the first optical axis. In the driving mode, the second lens module 230 can include the 1-2 lens group 232 and the 2-2 lens group 234 aligned along the second optical axis. The plurality of first lens groups 212 and 232 disposed on the first holder 11 can be spaced apart from each other by a first interval. The plurality of second lens groups 214 and 234 disposed on the second holder 21 can be spaced apart from each other by the first interval. The plurality of first lens groups 212 and 232 can include the 1-1 lens group 212 and the 1-2 lens group 232 spaced apart from each other in the first direction X. The plurality of second lens groups 214 and 234 can include the 2-1 lens group 214 and the 2-2 lens group 234 spaced apart from each other in the first direction X. The first holder 11 and the second holder 21 can be non-magnetic. The first holder 11 and the second holder 21 can be made of metal or plastic, in the case of a metal material, it can block electromagnetic interference noise, and in the case of a plastic material, it can reduce weight and can be easily combined with a lens.

[0055] The length of the first holder 11 in the first direction X can be the same as or different from the length of the second holder 21 in the first direction X. The length of the first holder 11 in the second direction Y can be the same as or different from the length of the second holder 21 in the second direction Y. Each of the first holder 11 and the second holder 21 can have a length in the first direction X greater than a length in the second direction Y. Here, the first direction X can be a direction in which the lens modules 210 and 230 are arranged, and the second direction Y can be a direction orthogonal to the first direction X. For example, as shown in FIG. 5, when the camera is disposed in the housing 501 of the terminal, the length in the first direction X can be longer than the length in the second direction Y. As shown in FIG. 6, when the camera is disposed in the terminal, the length in the second direction Y can be longer than the length in the first direction X. As shown in FIG. 7, when the camera is disposed in the terminal, the length in the first direction X and the length in the second direction Y can be the same as or different from each other. Figure 1 Figure 29 Figure 30

[0056] As shown in FIG. 5, when the camera is disposed in the housing 501 of the terminal, the length in the first direction X can be longer than the length in the second direction Y. As shown in FIG. 6, when the camera is disposed in the terminal, the length in the second direction Y can be longer than the length in the first direction X. As shown in FIG. 7, when the camera is disposed in the terminal, the length in the first direction X and the length in the second direction Y can be the same as or different from each other. Figure 25 ​​​As shown, the first holder 11 and the second holder 21 can not be physically connected to each other. The first holder 11 and the second holder 21 can not be electrically connected to each other. In the driving mode, the first holder 11 can protrude more than 4 mm outside the housing of the terminal. The image sensor module 30 can be disposed below the first lens group 11 and / or the second lens group 21. For example, the image sensors 35 and 35A can include a first image sensor 35 and a second image sensor 35A spaced apart in the first direction X.

[0057] In the first lens module 210, in the 1-1 lens group 212, three or four lenses are stacked from the object side toward the sensor side, and the 2-1 lens group 214 includes three lenses to five lenses. The lenses can be stacked from the object side toward the sensor. The first lens module 210 can include six lenses to nine lenses, and can include a solid lens or at least one liquid lens between the solid lenses. The liquid lens can be disposed on at least one of the plurality of second lens groups or two of the second lens groups. Such a liquid lens includes a cavity having a conductive liquid and a non-conductive liquid therein, and can control the interface between the two liquids to be concave, flat, or convex by controlling the applied power.

[0058] In the second lens module 230, in the 1-2 lens group 232, three or four lenses are stacked from the object side toward the sensor side, and the 2-2 lens group 234 includes three lenses to five lenses. The lenses can be stacked from the object side toward the sensor. The second lens module 230 can include six lenses to nine lenses, and can be composed of solid lenses, or at least one liquid lens can be disposed between the solid lenses. Here, in the driving mode, the maximum distance between the two lenses spaced farthest apart between the lenses of the first holder 11 and the lenses of the second holder 21 facing each other can be 4 mm or more, for example, in the range of 4 mm to 9 mm. Here, for the maximum distance, in the mode in which the first lens groups 212 and 232 of the first lens module 210 and the second lens module 230 are moved (popped out) in the optical axis direction from the second lens groups 214 and 234, the distance between the first holder 11 and the second holder 21 can be the largest.

[0059] In this way, the plurality of lens modules 210 and 230 are like Figure 31 and Figure 30As illustrated, the first holder 11 and the second holder 21 are vertically separated in the driving mode, and the first holder 11 and the second holder 21 can be separated in the horizontal direction in the non-driving mode. Accordingly, in the driving mode, the first holder 11 having the plurality of first lens groups 212 and 232 is moved by optimizing the distance between two adjacent lenses, and the plurality of first lens groups 212 and 232 can be aligned with the optical axis of each of the second lens groups 214 and 234 in the popped-out state.

[0060] In the driving mode, the 1-1 lens group 212 and the 2-1 lens group 214 of the first lens module 210 can overlap the first image sensor 35 in the vertical direction. The 1-2 lens group and the 2-2 lens group 234 of the second lens module 230 can overlap the second image sensor 35A vertically. In the non-driving mode, the first holder 11 overlaps the first image sensor 35 and the second image sensor 35A vertically, and the second holder 21 can not overlap the first image sensor 35 and the second image sensor 35A in the vertical direction. Here, in the first example, the printed circuit board 30 is separated from the second holder 21 and only the second holder 21 can move in the horizontal direction, and the first image sensor 35 and the second image sensor 35A can be positioned in a state of alignment with the optical axis of the first lens groups 212 and 232 before or after the movement. In the first example, since the printed circuit board 30 is fixed, it can be advantageous in terms of structure and space. In another second example, the printed circuit board 30 is connected to the second holder 21, the printed circuit board 30 and the second holder 21 can move together, and the first image sensor 35 and the second image sensor 35A can be positioned in a state of alignment with the optical axis of the second lens groups 214 and 234 before or after the movement. As in the second example, when the printed circuit board 30 and the second holder 21 move together, the number of cases considering the optical axis can be reduced, and thus the optical performance can be improved.

[0061] The first image sensor 35 can convert light incident through the first lens module 210 into an electrical signal. The second image sensor 35A can convert light incident through the second lens module 230 into an electrical signal. The image sensors 35 and 35A can be any one of a charge-coupled device (CCD), a complementary metal-oxide semiconductor (CMOS), a CPD, and a CID. Any one of the image sensors 35 and 35A can be a color (RGB) sensor, and the other can be a black-and-white sensor.

[0062] The first image sensor 35 and the second image sensor 35A can be disposed on one printed circuit board 31. The ratio of the length of the long side to the length of the short side in the first image sensor 35 and the second image sensor 35A can be 4:3 or 16:9. The printed circuit board 31 can include an FPCB. A filter can be disposed on the image sensors 35 and 35A. A first filter (not shown) can be disposed on the first image sensor 35, and the first filter can be disposed inside the second holder 21. The first filter can be disposed between the 2-1 lens group 214 of the second holder 21 and the first image sensor 35. The first filter can be an infrared filter, and can block light in an infrared region from being incident on the first image sensor 35. A second filter (not shown) can be disposed on the second image sensor 35A, and the second filter can be disposed inside the second holder 21. The second filter can be disposed between the 2-2 lens group 234 of the second holder 21 and the second image sensor 35A. The second filter can be an infrared filter, and can block light in an infrared region from being incident on the second image sensor 35A. The first filter and the second filter can be formed by applying an infrared blocking coating material on a plate-shaped filter (e.g., a cover glass) to protect an imaging surface or a cover glass. The first filter and the second filter can be an infrared absorption filter or an infrared reflection filter.

[0063] The lenses of the first lens module 210 and the lenses of the second lens module 230 can have different Fno (F number). The first lens module 210 and the second lens module 230 can produce images having a difference in image brightness or image quality. For example, one of the first lens module 210 and the second lens module 230 can be a wide-angle lens module or a telephoto lens module, and the other can be a main lens module or a general lens module. The wide-angle lens module can photograph an object having a wider width than that of the main lens module. The telephoto lens module can photograph an object at a certain distance compared to the standard lens module. Either of the first lens module 210 and the second lens module 230 can be a super wide-angle lens module. The super wide-angle lens module can be provided with a wider angle of view than the wide-angle lens module, for example, the angle of view of the wide-angle lens module can be 45 degrees or more or in the range of 45 degrees to 90 degrees, and the angle of view of the super wide-angle lens module can be 120 degrees or more. Since various function lens modules are installed in the camera module, user convenience can be improved and the quality of the photographed image can be improved. The first lens module 210 can have a focal length of 3 mm or more, for example, in the range of 3 mm to 10 mm. The focal length of the second lens module 230 can be greater than that of the first lens module 210, and can be 10 mm or more, for example, in the range of 10 mm to 14 mm. As another example, the sizes of the first image sensor 35 and the second image sensor 35A can be different from each other.

[0064] As Figure 32 shown, in the driving mode, the first holder 11 and the second holder 21 can overlap the image sensors 35 and 35A in the vertical direction. As Figure 33 shown, when switched to the non-driving mode, the second holder 21 can move in the horizontal direction M1, and the first holder 11 can move in the sensor direction M2. Here, when switched from the driving mode to the non-driving mode, the first holder 11 can move from the first region R1 exposed to the outside of the housing of the terminal toward the third region R3, and the second holder 21 can move from the third region R3 toward the second region R2 spaced apart in the horizontal direction. Accordingly, in the driving mode, the first holder 11 and the second holder 21 overlap in the vertical direction, and in the non-driving mode, the first holder 11 and the second holder 21 can overlap in the horizontal direction, so that the height of the camera module can be reduced. Here, the thickness of the first holder 11 and the second holder 21 on the printed circuit board 31 before the ejection can be 5 mm or less, and the total thickness of the first holder 11 after the ejection can be in the range of 10 mm ± 1 mm. Here, the difference in the height of the first holder 11 before and after the driving can be about 1 / 2 of the thickness of the first holder 11. By providing a longer total length (TTL) of the camera module with the thickness due to the ejection state, the optical performance can be improved. Here, the lenses of the first lens group and the lenses of the second lens group can be distinguished based on the optical system having the longest length among the plurality of lens modules, for example, the telephoto lens module. Or, the lenses of the first lens group and the lenses of the second lens group can be distinguished based on the TTL of the optical system having the largest image sensor. The camera device can include a plurality of driving units and a control portion to drive each of the first holder 11 and the second holder 21. The plurality of driving units can include a first driving unit (not shown) to drive the first holder 11 in the vertical direction and a second driving unit (not shown) to drive the second holder 21 in the horizontal direction. Each of the first driving unit and the second driving unit can include at least one of a piezoelectric member, an actuator, or a stepping motor. As another example, the driving unit can include a plurality of leaf springs, and elasticity in the vertical direction can be provided by the leaf springs. As another example, a Hall sensor can be provided on at least one of the first holder 11 and the second holder 21, and the Hall sensor can detect movement in the vertical direction.

[0065] As Figure 32 (A) and Figure 25As shown in (B), the first driving unit can include a first guide shaft 41, a first moving part 43 connected to the first guide shaft 41 and the first holder 11, and a first driving part (not shown) for flowing the first moving part 43 through the first guide shaft 41. The second driving unit can include a second guide shaft 51, a second moving part 53 connected to the second guide shaft 51 and the second holder 21, and a second driving part (not shown) for moving the second moving part 53 through the second guide shaft 51. The first driving part and the second driving part can be implemented as a piezoelectric member or a stator such as a coil. The piezoelectric member is stretched or contracted when a voltage is applied to transmit the above-mentioned flow to the first guide shaft 41 and the second guide shaft 51. The first guide shaft 41 extends in the vertical direction along the first region R1 and the third region R3, is connected to the outside of the first holder 11, and can be arranged in one or more. The second guide shaft 51 extends in the horizontal direction along the second region R2 and the third region R3, is connected to the outside of the second holder 21, and can be arranged in one or more. The first guide shaft 41 and the second guide shaft 51 can be disposed in directions perpendicular to each other. The first moving part 43 can move vertically along the first guide shaft 41 together with the first holder 11. The second moving part 53 can move in the horizontal direction along the second guide shaft 51 together with the second holder 21. The first holder 11 and the second holder 21 can be moved simultaneously. The moving distance of the first holder 11 can be shorter than the moving distance of the second holder 21.

[0066] As shown in Figure 1 , which is a configuration showing another example of the first driving unit. The first driving unit can include a first guide shaft 41, an intermediate guide shaft 42, a first connecting part 43A, and an intermediate connecting part 43B. The first guide shaft 41 and the intermediate guide shaft 42 can move the first holder 11 in the upward or downward direction in a multi-stage manner. By moving the first holder 11 in such a multi-stage manner, the height of the fixed first guide shaft 41 can not be increased. Specifically, as shown in Figure 25 , the intermediate guide shaft 42 is disposed inside the first guide shaft 41, that is, in a region adjacent to the first holder 11. The upper end of the intermediate guide shaft 42 can be moved from a position higher than the upper end of the first guide shaft 41 to a lower position.

[0067] As shown in Figure 26 , when the intermediate guide shaft 42 can be driven by the third driving part, the first connecting part 43A and the first holder 11 can be moved in the downward direction, and then in Figure 27In the illustrated state, when the first holder 11 is disposed on the upper portion of the third region R3, the first guide shaft 41 is driven by the first driving portion, and thus the intermediate connection portion 43B connected to the first guide shaft 41 can move the first holder 11 toward the lower portion of the third region R3 or the sensor. Thus, as illustrated, the first guide shaft 41 and the intermediate connection portion 43B can position the first holder 11 at a position closest to the image sensors 35 and 35A. The third driving portion can include a piezoelectric member. Figure 27

[0068] Figure 25 is a view illustrating a camera module according to a second embodiment, and detailed description of configurations identical to those of the first embodiment will be omitted.

[0069] Referring to Figure 27 ​The camera module can include three lens modules. The camera module can include a first holder 11 and a second holder 21 and a first lens module 210, a second lens module 230, and a third lens module 250 aligned with different optical axes. The camera module can include a first image sensor 36, a second image sensor 37, and a third image sensor 38 disposed on one printed circuit board 450. The first holder 11 can include three or more first lens groups 212, 232, and 252. The second holder 21 can include three or more second lens groups 214, 234, and 254. The first holder 11 can include a 1-1 lens group 212, a 1-2 lens group 232, and a 1-3 lens group 252, and the second holder 21 can include a 2-1 lens group 214, a 2-2 lens group 234, and a 2-3 lens group 254. The first lens module 210 vertically overlaps the first image sensor 36, the second lens module 230 vertically overlaps the second image sensor 37, and the third lens module 250 can vertically overlap the third image sensor 38. A filter (not shown) can be disposed on each of the first image sensor 36, the second image sensor 37, and the third image sensor 38. The first image sensor 36, the second image sensor 37, and the third image sensor 38 can be disposed on one printed circuit board 31 to be spaced apart from each other. The first lens module 210 can be a wide-angle lens module, the second lens module 230 can be a main lens module or a general lens module, and the third lens module 250 can be a telephoto lens module. Here, the Fno of the telephoto lens module can be 1.8 or less. Any one of the first lens module 210, the second lens module 230, and the third lens module 250 can be implemented as a super wide-angle lens module. The super wide-angle lens module can be provided with a wider angle of view than that of the wide-angle lens module, for example, the angle of view of the wide-angle lens module can be 45 degrees or more or in the range of 45 degrees to 90 degrees, and the angle of view of the super wide-angle lens module can be 120 degrees or more. By installing various functional lens modules in the housing 100, the convenience of the user can be improved and the quality of the photographed image can be improved.

[0070] The first lens module 210 can have a focal length of 3 mm or more, for example, in a range of 3 mm to 10 mm. The second lens module 230 can have a focal length greater than that of the first lens module 210, and can be 10 mm or more, for example, in a range of 10 mm to 14 mm. The third lens module 250 can have a focal length of 10 mm or more, for example, in a range of 10 mm to 14 mm. The first lens module 210, the second lens module 230, and the third lens module 250 can have different focal lengths or the sizes of the first image sensor 36, the second image sensor 37, and the third image sensor 38 can be adjusted to improve image quality in a desired shooting mode. In this case, the distance between the lens groups of the telephoto lens module having the greatest focal length among the lens modules can be set as a reference, and then the distances between the lens groups of the other lens modules can be set. The length of the first holder 11 and the second holder 21 in one direction X can be greater than or equal to the length in the other direction. For example, as shown in FIG. 10, the camera module can be disposed under the housing 501 of the terminal, and can protrude when the first holder having the first lens group is driven. Figure 25

[0071] The plurality of first lens groups 212, 232, and 252 disposed in the first holder 11 can be disposed to be spaced apart from each other by a first interval. The plurality of second lens groups 214, 234, and 254 disposed on the second holder 21 can be disposed to be spaced apart from each other by the first interval. The plurality of first lens groups 212, 232, and 252 can include the 1-1 lens group 212, the 1-2 lens group 232, and the 1-3 lens group 252 spaced apart from each other in the first direction. The plurality of second lens groups 214, 234, and 254 can include the 2-1 lens group 214, the 2-2 lens group 234, and the 2-3 lens group 254 spaced apart from each other in the first direction. Here, the first lens module 210 can include the 1-1 lens group 212 and the 2-1 lens group 214 aligned along the first optical axis. The second lens module 230 can include the 1-2 lens group 232 and the 2-2 lens group 234 aligned along the second optical axis. The third lens module 250 can include the 1-3 lens group 252 and the 2-3 lens group 254 aligned along the third optical axis.

[0072] ​In the first lens module 210, three or four lenses are stacked from the object side toward the sensor side in the 1-1 lens group 212, and the 2-1 lens group 214 includes three lenses to five lenses. The lenses can be stacked from the object side toward the sensor side. The first lens module 210 can include six lenses to nine lenses, and can be made of solid lenses, or at least one liquid lens can be provided between the solid lenses, in which the liquid lens is supplied with a power source. In consideration of this, it can be provided in the second holder. In the second lens module 230, three lenses or four lenses are stacked from the object side toward the sensor side in the 1-2 lens group 232, and the 2-2 lens group 234 includes three lenses to five lenses. The lenses can be stacked from the object side toward the sensor side. The second lens module 230 can include six lenses to nine lenses, and can be made of solid lenses, or at least one liquid lens can be provided between the solid lenses. In the third lens module 250, two or three lenses are stacked from the object side toward the sensor side in the 1-3 lens group 252, and the 2-3 lens group 254 includes three lenses to five lenses. The lenses can be stacked from the object side toward the sensor side. The third lens module 250 can include five lenses to eight lenses, and can be made of solid lenses, or at least one liquid lens can be provided between the solid lenses.

[0073] As Figure 27 shown, the first holder 11 is driven by a first driving unit, which can include a first guide shaft 121 provided outside the first holder 11, a first connecting part 123 connected with the first guide shaft 121 and the first holder 11, and a first driving part 125 for driving the first guide shaft 121. The second holder 21 is driven by a second driving unit, which can include a second guide shaft 151 provided outside the moving distance of the second holder 21, a second connecting part 153 connected with the second guide shaft 151 and the second holder 21, and a second driving part 155 for driving the second guide shaft 151. The first driving part 125 and the second driving part 155 can be piezoelectric members, and as another example, can be implemented as an actuator or a stepping motor. One or more of the first driving units can be arranged to stably raise or lower the first holder 11 in the vertical direction. One or more of the second driving units can be arranged to move the second holder 21 upward or downward in the horizontal direction.

[0074] When Figure 27 the state shown in FIG. 1A is switched to Figure 27 , it is in a driving mode, and the first holder 11 is raised in the vertical direction M2 by the first driving unit 121, 123, and 125, and the second holder 21 can be moved toward the sensor in the horizontal direction M1 by the second driving unit 151, 153, and 155. When Figure 26The illustrated state is switched to Figures 32 to 34 In the state of FIG. 27, the second holder 21 is in the non-driving mode, and the first holder 11 can be moved in the vertical direction M2 by the first driving unit 121, 123, and 125, and the second holder 21 can be moved in the horizontal direction M1 by the second driving unit 151, 153, and 155. Thus, the moving distance G1 of the first holder 11 can be 4 mm or more. Here, in the driving mode, the maximum distance between the lenses of the first holder 11 and the lenses of the second holder 21 can be 4 mm or more, for example, it can be in the range of 4 mm to 9 mm. Here, the maximum distance is the distance in the mode (pop-up) in which the first lens groups 212, 232, and 252 of the first lens module 210, the second lens module 230, and the third lens module 250 are moved in the optical axis direction from the second lens groups 214, 234, and 254 to the surface of the housing 501, and the distance between the first holder 11 and the second holder 21 can be the largest. Here, the moving distance G1 of the first holder 11 can be about 1 / 2 of the thickness of the first holder 11. The distance between two adjacent ones of the first optical axis, the second optical axis, and the third optical axis of the first lens module 210, the second lens module 230, and the third lens module 250 can be constant or one of them can be larger, but the present application is not limited thereto. As another example, a quadruple lens module can be included in the first holder 11 and the second holder 21. The quadruple lens module can be a first lens module to a fourth lens module, and can include the first lens module 210, the second lens module 230, and the third lens module 250 disclosed above and a lens module for Time of Flight (ToF) (for example, the one disclosed in FIG. 27). Such a TOF lens module and an image sensor can provide depth data as well as two-dimensional data. Alternatively, the ToF lens module can be applied as the third lens module 250. When such a ToF lens module is applied, the camera device can include an infrared element. Figure 32

[0075] In Figure 26 , an example in which the second holder 21 moves in a direction orthogonal to the direction in which the plurality of lens modules 210, 230, and 250 are disposed, that is, in the short side direction of the second holder 21 has been described. As Figure 27 and Figure 27 indicated, an example in which the second holder 21 moves in the same direction as the direction in which the plurality of lens modules 210, 230, and 250 are disposed, that is, in the long side direction of the second holder 21 has been described. Such movement of the second holder 21 can be used in the camera structure of the terminal as Figure 26 and Figure 32 indicated.

[0076] As​Figure 26 of (A) and Figure 27 of (B), the thickness T2 of the camera module, i.e., the height from the printed circuit board to the upper end of the first holder 11 (i.e., T2) can be greater than the height T1 of the accommodation space of the mobile terminal. Accordingly, the first holder 11 can move by a distance G1 obtained by the difference between the two heights T2-T1 in the upward or downward direction. Here, in the driving mode, the first holder 11 can protrude by the distance G1 to the outside of the housing 501, and in the non-driving mode, the first holder 11 can move by the distance G1 in the downward direction. The 1-1 lens group 213 of the first holder 11 and the 2-1 lens group 215 of the second holder 21 can be aligned with the first optical axis P1, and thus can operate in the photographing mode. The 1-2 lens group 233 of the first holder 11 and the 2-2 lens group 235 of the second holder 21 can be aligned with the second optical axis P2, and thus can operate in the photographing mode. Here, the filters F1 and F2 can be disposed between the second holder 21 and the image sensors 36 and 37, respectively. In this camera module, the lenses of the 1-1 lens group 213 of the first lens module of the first holder 11 and the lenses of the 1-2 lens group 215 of the first lens module of the second holder 21 can be aligned from the object side toward the sensor side. The aperture can be located at the edge of the object side surface of the first lens or the second lens of each of the plurality of first lens groups, and can be disposed at the edge of the object side surface of the first lens or the second lens according to each lens module. Here, as shown in FIGS. 10A and 10B, the first lens module 210 can be a main lens module, and the second lens module 220 can be a sub lens module. The first lens module 210 can include the 1-1 lens group 212 and the 1-2 lens group 213, and the second lens module 220 can include the 2-1 lens group 214 and the 2-2 lens group 215. Figure 28 and Figure 29 As shown in FIGS. 10A and 10B, when the first lens module 210 is a main lens module, the 1-1 lens group 212 and 213 can be stacked in two or three lenses, and can have a total positive refractive power. For example, in the first lens module 210, the object side lens (the lens closest to the object) and the last sensor side lens (the lens closest to the sensor) of the 1-1 lens group 212 and 213 can have a positive refractive power. When the 1-1 lens group 212 and 213 are two lenses, the focal length of the object side lens can be 0.7 times or more, for example, between 0.7 times and 1.5 times, of the total focal length of the first lens group. When the 1-1 lens group 212 and 213 are stacked with three lenses, among the lenses of the 1-1 lens group 212 and 213, the refractive power from the object side lens to the sensor side surface (the sensor side surface of the last lens) separated from the 2-1 lens group 214 and 215 can have a positive refractive power, and the focal length of the object side lens can be 1.5 times or more, for example, in the range of 1.5 times to 3 times, of the total focal length of the 1-1 lens group 212 and 213.

[0077] The 2-1 lens groups 214 and 215 of the first lens module 210 can be composed of 3 or 4 elements, the total refractive power can have a negative refractive power, and the object side lens and the sensor side lens of the 2-1 lens group 215 can have a negative refractive power. In the second lens groups 214 and 215, the focal length of the sensor side lens can be 0.15 times or more of the focal length of the entire 2-1 lens group, for example, 0.15 to 1.5 times. In the 2-1 lens groups 214 and 215 of the first lens module 210, the object side lens can have a sagittal height (Sag) value of 0.01 mm or less, which reaches a height of 25% of the effective diameter of the lens, to reduce sensitivity to lateral decentration. The total TTL (distance from the object side lens to the sensor) of the first lens module 210 having the 1-1 lens groups 212 and 213 and the 2-1 lens groups 214 and 215 can be in the range of 90% to 100% of the thickness of the terminal on which the optical system is mounted. The thickness of the 1-1 lens groups 212 and 213 or the first holder 11 disclosed above can be 40% or less of the TTL of the entire optical system, for example, in the range of 30% to 40%. The thickness of the 1-1 lens groups 212 and 213 or the first holder 11 can be formed in consideration of the thickness of the mobile terminal or camera accommodation space. The thickness or height of the 2-1 lens groups 214 and 215 or the second holder 21 can be set in the range of 30% or more of the TTL of the entire optical system, for example, 30% to 60%. In the driving mode, the distance between the 1-1 lens groups 212 and 213 or the first holder 11 and the 2-1 lens groups 214 and 215 or the second holder 21 is 20% or less of the entire optical system, for example, in the range of 10% to 20%.

[0078] When the second lens module 230 is a long focus lens module, the first lens group 232 and the second lens group 233 can consist of three lenses, have a total refractive power of positive refractive power, and the object side lens and the sensor side lens can have positive refractive power. The focal length of the object side lens of the first lens group 232 and the second lens group 233 can be 0.6 times or more of the total focal length of the first lens group 232 and the second lens group 233, for example, between 0.6 times and 1.5 times. Here, the aperture can be disposed on the object side edge of the first lens and the object side edge of the second lens of the first lens group 232 and the second lens group 233. The 2-2 lens group 234 and 235 of the second lens module 230 can consist of two lenses, have a total refractive power of negative refractive power, and the object side lens and the sensor side lens have negative refractive power. The focal length of the sensor side lens of the 2-2 lens group 234 and 235 can be 1.5 times or more of the total focal length of the 2-2 lens group 234 and 235, for example, 1.5 times to 2.5 times. The object side lens of the 2-2 lens group 234 and 235 can be configured to have a sag value of 0.01 mm or less, which reaches 25% of the lens effective diameter, to reduce sensitivity due to horizontal decentration.

[0079] The total TTL (length from the surface of the first lens to the sensor) of the second lens module 230 can be 90% to 100% of the thickness of the terminal to which the optical system is to be mounted, and the thickness of the holder having the 1-2 lens group and the 2-2 lens group can be divided in a ratio with respect to the total optical system length (TTL). For example, the thickness of the first holder 11 having the 1-2 lens group 232 and 233 can be 40% or less of the total optical system length TTL, for example, in the range of 30% to 40%. The thickness of the second holder 21 having the 2-2 lens group 234 and 235 can be 60% or less of the total optical system TTL, for example, in the range of 50% to 60%. The thickness of the first lens group 232 and the second lens group 233 or the first holder 11 can be formed in consideration of the thickness of the mobile terminal or the space for accommodating the camera. The interval between the 1-2 lens group 232 and 233 or the first holder 11 and the 2-2 lens group 234 and 235 or the second holder 21 can be in the range of 20% or less of the total optical system, for example, in the range of 10% to 20%. As shown in FIG. 10, the first lens group 212, 232, and 252 of the plurality of lens modules disposed in the first holder 11 assume a vertically upward state, and when not driven, they can drop to the same position as the surface of the housing. Figure 35

In describing the third embodiment, the same configurations as the first and second embodiments can be selectively included in the description of the first and second embodiments.

[0081] Referring to ​ , the camera module can include a housing 100 including a first holder 110 having a plurality of first lens groups 212 and 232 and a second holder 120 having a plurality of second lens groups 214 and 234, and an image sensor module 400 that converts light incident through the first lens groups 212 and 232 and the second lens groups 214 and 234 into an electrical signal. The camera module can include a module having a plurality of lens modules 210 and 230 and a plurality of image sensors 410 and 430. The first holder 110 can be coupled to an inner portion of the second holder 120 or to an upper portion of the second holder 120. The first holder 110 and the second holder 120 can be disposed to overlap in a vertical direction.

[0082] As shown in ​ , the second holder 120 has a receiving space 115, and the first holder 110 can be inserted into the receiving space 115 of the second holder 120. The second holder 120 can not be physically connected with the first holder 110. The inner lens groups 214 and 234 of the receiving space 115 can be connected by a support portion 122. A vertical thickness of the first holder 110 can be the same as a depth of the receiving space 115 of the second holder 120, for example, can be 4 mm or less. Here, the receiving space 115 can include a structure having a side wall facing a portion of at least one side surface or both side surfaces of the first holder 110. That is, the side wall of the receiving space 115 can be a structure having a minimum height that can be guided when the first holder 110 moves from the second holder 120 in an optical axis direction. As another example, the second holder 120 can have a flat top surface without the receiving space 115. ​

[0083] As ​ illustrated, a length D3 of the first holder 110 in the first direction X can be less than or equal to a length D0 of the second holder 120 in the first direction X. A length D4 of the first holder 110 in the second direction Y can be less than or equal to a length D2 of the second holder 120 in the second direction Y. The length D3 of the first holder 110 in the first direction X can be greater than the length D4 in the second direction Y. The length D0 of the second holder 120 in the first direction X can be greater than the length D2 in the second direction Y. Here, the first direction X can be a direction in which the lens modules 210 and 230 are arranged, and the second direction Y can be a direction orthogonal to the first direction X. The housing 100 can be provided in a top view shape of a rectangle or a regular rectangle. For example, as ​ illustrated, when the housing 100 is provided in the housing 501 of the terminal, the length in the first direction X can be longer than the length in the second direction Y. As ​ illustrated, when the housing is provided in the terminal, the length in the second direction Y can be longer than the length in the first direction X. As ​ illustrated, when the housing is provided in the terminal, the length in the first direction X and the length in the second direction Y can be the same as or different from each other.

[0084] As ​ and 17 illustrated, the housing 100 can include a plurality of lens modules 210 and 230. The plurality of lens modules 210 and 230 can include a first lens module 210 and a second lens module 230 spaced apart in the first direction X. Here, the first lens module 210 can include a 1-1 lens group 212 and a 2-1 lens group 214 aligned along a first optical axis. The second lens module 230 can include a 1-2 lens group 232 and a 2-2 lens group 234 aligned along a second optical axis. The plurality of first lens groups 212 and 232 provided on the first holder 110 can be spaced apart from each other by a first interval D1. The plurality of second lens groups 214 and 234 provided on the second holder 120 can be spaced apart from each other by a first interval. The plurality of first lens groups 212 and 232 can include the 1-1 lens group 212 and the 1-2 lens group 232 spaced apart in the first direction X. The plurality of second lens groups 214 and 234 can include the 2-1 lens group 232 and the 2-2 lens group 234 spaced apart from each other in the first direction X. The first holder 110 and the second holder 120 can be non-magnetic. The first holder 110 and the second holder 120 can be made of a metal material or a plastic material, and in the case of the metal material, it can block electromagnetic interference noise, and in the case of the plastic material, it can reduce weight and can be easily combined with a lens.

[0085] As ​As illustrated, the image sensor module 240 can include a plurality of image sensors 410 and 430 and a printed circuit board 450 on which the plurality of image sensors 410 and 430 are disposed. For example, the image sensors 410 and 430 can include a first image sensor 410 and a second image sensor 430 spaced apart in a first direction X. In the first lens module 210, the 1-1 lens group 212 can have three to four lenses, and the 2-1 lens group 214 can have three to five lenses. The first lens module 210 can include six to nine lenses, and can include a solid lens or at least one liquid lens between the solid lenses. The liquid lens can be disposed on at least one or two of the plurality of second lens groups. In the second lens module 230, the 1-2 lens group 232 can have three or four lenses, and the 2-2 lens group 234 can have three to four lenses. The second lens module 230 can include six to nine lenses, and can consist of solid lenses, or at least one liquid lens can be disposed between the solid lenses. Here, in a non-actuated mode, the minimum distance between two lenses closest to each other between the lenses of the first holder 110 and the lenses of the second holder 120 facing each other can be 0.5 mm or less, for example, in the range of 0.1 mm to 0.5 mm. Here, for the minimum distance, the distance between the first holder 110 and the second holder 120 can be the minimum in the case where the first lens module 210 and the second lens module 230 are not actuated or not used. Here, the maximum distance between two lenses spaced the most apart from each other between the lenses of the first holder 11 and the lenses of the second holder 21 facing each other can be 4 mm or more, for example, in the range of 4 mm to 9 mm. Here, the maximum distance is in the mode where the first lens groups 212 and 232 of the first lens module 210 and the second lens module 230 are moved (popped out) in the optical axis direction from the second lens groups 214 and 234, and the distance between the first holder 11 and the second holder 21 can be the maximum. In this way, the plurality of lens modules 210 and 230 are vertically separated into the first holder 110 and the second holder 120, and since the distance between two adjacent lenses is optimized, the first holder 11 having the plurality of first lens groups 212 and 232 is moved, and the plurality of first lens groups 212 and 232 can be aligned with the second lens groups 214 and 234 in the popped-out state in the optical axis direction.

[0086] The 1-1 lens group 212 and the 2-1 lens group 214 of the first lens module 210 can overlap the first image sensor 410 in a vertical direction. The 1-2 lens group and the 2-2 lens group 234 of the second lens module 230 can overlap the second image sensor 430 in a vertical direction. The first image sensor 410 can convert light incident through the first lens module 210 into an electrical signal. The second image sensor 430 can convert light incident through the second lens module 230 into an electrical signal. Either one of the image sensors 410 and 430 can be a color (RGB) sensor, and the other can be a black-and-white sensor. A light filter can be disposed on the image sensors 410 and 430.

[0087] The first lens module 210 and the second lens module 230 can produce images having a difference in image brightness or image quality. For example, one of the first lens module 210 and the second lens module 230 can be a wide-angle or telephoto lens module, and the other can be a main lens module or a general lens module. Either one of the first lens module 210 and the second lens module 230 can be a super wide-angle lens module. Since lens modules of various functions are mounted on the housing 100, user convenience can be improved and the quality of a photographed image can be improved.

[0088] The first lens module 210 can have a focal length of 3 mm or more, for example, in a range of 3 mm to 10 mm. The focal length of the second lens module 230 can be greater than that of the first lens module 210, and can be 10 mm or more, for example, 10 mm to 14 mm. As another example, the sizes of the first image sensor 410 and the second image sensor 430 can be different from each other. The second holder 120 can have a receiving space 115 on an upper portion or inside thereof, and the first holder 110 can be inserted or coupled to the receiving space 115. The first holder 110 is disposed in the receiving space 115 of the second holder 120, and the first holder 110 can be moved vertically upward or downward to an initial position with respect to the second holder 120 by a driving portion.

[0089] As ​ and ​As shown, the stator 363 can be disposed on at least one side or both sides of the outer side surface of the first holder 110. The stator 363 can be disposed to have a longer length in a direction in which the lens modules 210 and 230 are arranged. The stator 363 can be disposed to have a longer length in the first direction X. The stator 363 can extend to the outside of the 1-1 lens group 212 and the 1-2 lens group 232. The movable member 361 can be disposed on the inner surface or the outer surface of the second holder 120 facing the stator 363. The movable member 361 can be disposed on the inner surface or the outer surface of the second holder 120 facing the stator 363. The movable member 361 can be disposed at a position facing one or more stators 363. The movable member 361 can be a magnet, and the stator 363 can include a coil. The driving unit 360 can include the movable member 361 and the stator 363. Here, the second holder 120 can be provided with a receiving groove for mounting the movable member 361 or can be provided with a plurality of holes 352 to transmit a magnetic field.

[0090] The first image sensor 410 and the second image sensor 430 can be electrically connected to the printed circuit board 450. The printed circuit board 450 can supply power to the stator 363. The printed circuit board 450 can include a controller (not shown) for controlling driving of the first holder 110. The stator 363 or the coil can move the first holder 110 in the vertically upward direction or the vertically downward direction by electromagnetic interaction with the magnet. The magnet and / or the coil can be used for AF driving and / or OIS driving. As another example, the driving unit can include a piezoelectric member disposed in the second holder 120 and a shaft that is a shaft guiding movement of the first holder 110, and the first holder 120 can be guided vertically upward or downward by the piezoelectric member. Accordingly, the driving member can include at least one of a piezoelectric member, an actuator, and a stepping motor, but is not limited thereto. As another example, the driving part can include a plurality of leaf springs, and elasticity in the vertical direction can be provided by the leaf springs. As another example, a Hall sensor can be disposed on at least one of the first holder 110 and the second holder 120, and the Hall sensor can detect movement in the vertical direction.

[0091] As shown in (A) of FIG. 10, the first holder 110 is disposed on the second holder 120 before the camera module is driven or when the camera device is not in use. The first holder 110 can be in close contact with the upper surface of the second holder 120 or can be in close contact with an interval of 1 mm or less. The upper surface of the first holder 110 can be disposed on the same horizontal surface as the upper surface of the second holder 120. As shown in (B) of FIG. 10, the first holder 110 can be disposed to be spaced apart from the second holder 120 by a predetermined distance. ​ ​ ​When the camera module is driven or the camera device is in a use mode, when power of the positive electrode is supplied to the stator 363 of the driving portion, the movable member 361 of the first holder 110 moves in the upward direction and protrudes a prescribed distance G1 in the upward direction from the surface of the housing 501 in the second holder 120. In this case, the first holder 110 can protrude a distance G1 in a range of 1 mm or more, for example, in a range of 3 mm to 4 mm, based on the upper surface of the second holder 120. For example, the first holder 110 can protrude in a range of 3 mm or more, for example, in a range of 3 mm to 7 mm, from the surface of the housing of the mobile terminal. In this case, the separation distance G2 between the first holder 110 and the second holder 120 can be 3 mm or more, for example, in a range of 3 mm to 7 mm. Here, the thickness of the first holder 110 and the second holder 120 on the printed circuit board 450 before the ejection can be 7 mm or less, and the thickness of the first holder 110 after the ejection can be in a range of 10 mm ± 1 mm. By providing a longer total length (TTL) of the camera module using the thickness due to the ejection state, the optical performance can be improved. In addition, by separating the adjacent upper / lower lens groups by the distance G2 as described above, a longer flange back length (FBL) can be provided. Thereafter, when the power supplied to the stator 363 is cut off or power of the opposite polarity is supplied to the stator 363, the first holder 110 can move to the initial position. The driving portion for controlling the movement of the first holder 110 can be controlled by the controller.

The super wide-angle lens module can be provided with a wider angle of view than the wide-angle lens module, for example, the angle of view of the wide-angle lens module can be 45 degrees or more or in the range of 45 degrees to 90 degrees, and the angle of view of the super wide-angle lens module can be 120 degrees or more. Since lens modules of various functions are installed in the housing 100, user convenience can be improved and the quality of the photographed image can be improved.

In this case, another lens module can be set based on a telephoto lens module having the largest focal length among each lens module.

Here, the first direction can be a direction in which the lens modules are arranged, and the second direction can be a direction orthogonal to the first direction. The housing 100 can be provided in a rectangular or regular rectangular plan view shape. When the housing 100 has a square shape, straight lines connecting the first lens module 210, the second lens module 230, and the third lens module 250 can be provided in a triangular shape.

Here, the housing 100 can include the first lens module 210, the second lens module 230, and the third lens module 250 arranged in one direction. The first lens module 210, the second lens module 230, and the third lens module 250 can be spaced apart from each other in the first direction X or the second direction Y. Here, the first lens module 210 can include the 1-1 lens group 212 and the 2-1 lens group 214 aligned along a first optical axis. The second lens module 230 can include the 1-2 lens group 232 and the 2-2 lens group 234 aligned along a second optical axis. The third lens module 250 can include the 1-3 lens group 252 and the 2-3 lens group 254 aligned along a third optical axis. In the first lens module 210, the 1-1 lens group 212 can have three lenses or four lenses, and the 2-1 lens group 214 can have three lenses to five lenses. The first lens module 210 can include six lenses to nine lenses, and can include a solid lens or at least one liquid lens between the solid lenses.

Here, in the non-driving mode, the minimum distance between the two lenses closest to each other between the lenses of the first holder 110A and the lenses of the second holder 120 can be 0.5 mm or less, for example, in the range of 0.1 mm to 0.5 mm. Here, the minimum distance is the distance when the first lens module 210, the second lens module 230, and the third lens module 250 are not driven or not used, and the distance between the first holder 110a and the second holder 120 can be the minimum. Here, the maximum distance between the two lenses spaced the most apart between the lenses of the first holder 110A and the lenses of the second holder 120 can be 4 mm or more, for example, can be in the range of 4 mm to 9 mm. Here, the maximum distance is the distance in the mode (pop-up) in which the first lens groups 212, 232, and 252 of the first lens module 210, the second lens module 230, and the third lens module 250 are moved from the second lens groups 214, 234, and 254 in the optical axis direction to above the surface of the housing 501, and the distance between the first holder 11 and the second holder 21 can be the maximum.

[0097] The distance between two adjacent ones of the first optical axis, the second optical axis, and the third optical axis of the first lens module 210, the second lens module 230, and the third lens module 250 can be constant or one of them can be larger, but the present application is not limited thereto. As another example, the housing 100 can include a four-fold lens module in the first holder 110A and the second holder 120. The four-fold lens module can be a first lens module to a fourth lens module, and can include the first lens module 210, the second lens module 230, and the third lens module 250 disclosed above, and a time-of-flight (ToF) lens module (for example, 272 in ​

[0098] ​ (A) of FIG. 1 and ​ (B) of FIG. 1 are examples illustrating a side cross-sectional view of a camera module according to a fourth embodiment. ​ ​Two lens modules are illustrated, but three or four lens modules can be included without being limited thereto. As ​ (A) and ​ (B) of FIG. 1, the housing can include a first holder 11 and a second holder 21 stacked in a vertical direction. The housing can include a plurality of lens modules 210 and 230, for example, can include at least two lens modules. Image sensors 410 and 430 and optical filters (not shown) disposed on a printed circuit board 450 can be disposed below the lens modules 210 and 230, respectively.

[0099] The first lens module 210 can include a 1-1 lens group 212 disposed in the first holder 110 and a 2-1 lens group 214 disposed in the second holder 230. The second lens module 230 can include a 1-2 lens group 232 disposed in the first holder 110 and a 2-2 lens group 234 disposed in the second holder 230.

Each of the 1-2 lens group 232 and the 2-2 lens group 234 of the second lens module 230 can include two or more lenses.

Here, the guide shaft 41 can be disposed not to be exposed to the outside of the housing of the terminal.

[0100] The camera module according to the first embodiment to the fourth embodiment can be combined with a front or a rear of a portable terminal. As ​ illustrated, a plurality of first lens groups 212, 232, and 252 can be arranged in a first direction and can be simultaneously vertically upward or downward. As ​ illustrated, a plurality of first lens groups 212, 232, and 252 can be arranged in a second direction and can be simultaneously vertically upward or downward. As ​As shown, the plurality of first lens groups 212, 232, and 252 can be arranged in the first direction and the second direction, and can be simultaneously vertically upward or downward. In ​ In the fifth embodiment, the ToF lens module 272 can be added to the first holder 11 or a camera flash module can be further provided, but the present application is not limited thereto. The housing 501 of such a terminal can have an opening through which the first holder 11 can protrude. In addition, by moving the second holder provided below the first holder 11 in the horizontal direction, the total thickness of the camera module can be manufactured to be thinner, and it can be applied to a smartphone having a thin thickness of 11 mm or less. Accordingly, a part of the first holder 11 can protrude only during use and can not protrude from the outside of the housing of the mobile terminal such as a smartphone. Accordingly, in a non-use mode of the camera, the problem that a part of the lens module of the camera device protrudes to the outside of the smartphone can be improved, making it easy to carry and the appearance design can be improved, and it can also protect the surface of the camera module from damage.

In the description of the fifth embodiment, the same configuration as the first embodiment includes the description of the first embodiment.

[0102] Referring to ​ The mobile terminal 500 according to an embodiment of the present application can be a portable electronic device equipped with a camera module 1000, for example, a mobile communication terminal, a smartphone, a tablet, etc. As shown in ​As shown, the mobile terminal 500 is equipped with a camera module 1000 to photograph an object. The camera module 1000 can include a plurality of lenses, optical axes (Z-axes) of the lenses can be in a direction perpendicular to a thickness direction (Z-axis direction) of the mobile terminal 500, and the thickness direction of the mobile terminal 500 can be a direction from a front surface to a rear surface of the terminal or a reverse direction. For example, the optical axes (Z-axes) of the plurality of lenses provided in the camera module 1000 can be formed in a width direction or a length direction (X-axis direction or Y-axis direction) of the mobile terminal 500. Accordingly, even if the camera module 1000 has functions such as auto focus (hereinafter, AF), zoom, and optical image stabilization (hereinafter, OIS), the thickness of the mobile terminal 500 is not increased. Accordingly, the size of the mobile terminal 500 can be reduced and a thinner thickness can be provided.

[0103] The camera module 1000 according to an embodiment of the present application can include at least one of AF, zoom, and OIS functions. The camera module 1000 having AF, zoom, and OIS functions, etc. needs to be provided with various components, such that the size of the camera module can increase compared to a general camera module. When the size of the camera module 1000 increases, it can become a problem of miniaturization of the mobile terminal 500 in which the camera module 1000 is mounted.

[0104] For example, in a camera module, the number of stacked lenses increases for a zoom function, and when a plurality of stacked lenses are formed in the thickness direction of a terminal, the thickness of the terminal also increases according to the number of stacked lenses. Therefore, when the thickness of the terminal does not increase, the number of stacked lenses cannot be sufficiently secured, and zoom performance is reduced. In addition, in order to implement AF and OIS functions, an actuator for moving a lens group in an optical axis direction or in a direction perpendicular to the optical axis should be installed, and when the optical axis of the lens group is formed in the thickness direction of the terminal, the actuator for moving the lens group should also be installed in the thickness direction of the portable electronic device. Therefore, the thickness of the terminal increases. However, in the camera module 1000 according to the embodiment of the present application, since the optical axes (Y axes) of the plurality of lenses are disposed perpendicular to the thickness direction of the mobile terminal 500 (i.e., parallel to the wide surface of the mobile terminal 500), the mobile terminal 500 can be miniaturized even though the camera module 1000 having AF, zoom, and OIS functions is installed. In addition, the camera module 1000 can slide downward in the optical axis Y direction and slide upward in the opposite direction. Therefore, the thickness in the vertical direction of the camera module 1000 which slides downward can be made thinner, thereby making the mobile terminal 500 smaller. Also, when the camera function is used, the camera module 1000 can slide upward so that it protrudes outside the housing 501 of the mobile terminal 500, and the center of the lens (i.e., the optical axis) can be aligned on the same line. Here, in the state of sliding downward, a part of the lens in the camera module 1000 on the edge side is supported to slide at a fixed position, and the other part on the edge side is inclined toward the light incident side in the optical axis direction. The upward sliding is an operation opposite to the downward sliding operation, and the optical axis can be aligned at the center of the lens. The sliding operation can be a sliding operation in one direction M5 or the opposite direction M6 or an inclination of the plurality of lenses. In ​ In the embodiment of the present application, in addition to the camera module 1000 according to the embodiment of the present application, a camera module having different performance can be further disposed in the housing 501 of the mobile terminal, but the present application is not limited thereto.

[0105] Referring to ​ and ​ , the camera module 1000 can include a first mirror 515, a lens module 510 having a plurality of lenses, and a second mirror 517. The camera module 1000 can include a printed circuit board 551 and an image sensor 553 disposed on the printed circuit board 551. The camera module 1000 can include a driving unit 530 for sliding or inclining the lens module 510, the first mirror 515, and the second mirror 517.

[0106] As ​As illustrated, the first mirror 515 can be disposed at an angle of 45 degrees to change the optical path of the incident light L0 irradiated from the upper portion to be a right angle. The first mirror 515 is a mirror closest to the object side, and can reflect the incident light toward the plurality of lenses. The second mirror 517 can be disposed at an angle of 45 degrees to change the optical path of the light incident through the plurality of lenses to be a right angle. The second mirror 517 is a mirror closest to the sensor, and can reflect the incident light toward the image sensor 553 and converge the light to the image sensor 553. The lens module 510 having the plurality of lenses can be disposed between the first mirror 515 and the second mirror 517. A first straight line passing through the center of the plurality of lenses can be an optical axis, and the light incident through the first mirror 515 is refracted to be emitted to the second mirror 517. An aperture can be disposed on the edge side of the incident surface (object side surface) of any one of the two lenses closest to the first mirror 515 among the plurality of lenses. The lens module 510 can include three or more lenses, for example, three lenses to seven lenses. Among the plurality of lenses, the lens closest to the first mirror 515 can have a positive refractive power, and the lens L1 closest to the second mirror 517 can have a negative refractive power. The plurality of lenses can include at least one or both of a lens having a positive refractive power and a lens having a negative refractive power. At least one or both of the plurality of lenses can include a convex surface or an aspheric surface in which at least one side or both sides of the incident surface and the exit surface are convex. At least one or both of the plurality of lenses can include a concave surface or a flat surface on which at least one of the incident surface and the exit surface is concave. The plurality of lenses can include a solid material or a lens using a liquid. The lens module 510 can include at least one liquid lens. The liquid lens has a conductive liquid and a non-conductive liquid in a cavity, and can adjust the curvature of the interface between the conductive liquid and the non-conductive liquid by an external power source. The liquid lens can be disposed closer to the first mirror 515 than the second mirror 517. As another example, the liquid lens can be disposed closer to the second mirror 517 than the first mirror 515. The width of the cavity of the liquid lens in a direction adjacent to the first mirror 515 can be greater than the width in a direction adjacent to the second mirror 517.

[0107] In the case of a second straight line extending in a direction perpendicular to the first straight line passing through the center of the plurality of lenses, the second straight line passing through the center surface or tangent of each lens can be disposed parallel to each other. The second straight line can be a thickness direction of the mobile terminal. ​ and ​ As illustrated, the upper portion of at least one lens or all of the plurality of lenses can protrude above the housing 501 of the mobile terminal. As illustrated, ​ and ​As illustrated, the upper portions of the first and second mirrors 515 and 517 can protrude from the upper portion of the housing 501 of the mobile terminal. The image sensor 553 converts light reflected by the second mirror 517 into an electrical signal. The image sensor 553 is mounted on the printed circuit board 551. The direction in which light is incident on the image sensor 553 can be a direction perpendicular to the optical axis. The direction horizontal to the upper surface of the printed circuit board 551 and the image sensor 553 can be a direction perpendicular to the optical axis.

[0108] The camera module 1000 according to an embodiment of the present application can include at least one of a wide-angle lens module, an ultra-wide-angle lens module, and a telephoto lens module. The ultra-wide-angle lens module can be provided with a wider angle of view than that of the wide-angle lens module, for example, the angle of view of the wide-angle lens module can be 45 degrees or more or in the range of 45 degrees to 90 degrees, and the angle of view of the ultra-wide-angle lens module can be 120 degrees or more. By mounting various functional lens modules, the convenience of the user can be improved and the quality of the photographed image can be improved. A filter (not shown) can be provided between the image sensor 553 and the second mirror 517. The camera device according to an embodiment of the present application can be disposed in the state ​ illustrated when the camera is in a non-driving mode or a non-use mode, and can be disposed in the state ​ illustrated when the camera is in a driving mode or a use mode.

[0109] As ​ illustrated, the camera module can include a holder 512 and guide shafts 521 and 523 formed around each of the plurality of lenses. The holder 512 can protect and support the periphery of each of the lenses. One or more guide shafts 521 and 523 can be provided outside the lens module 510, for example, two or three guide shafts 521 and 523 can be provided outside the lens module 510. The two guide shafts 521 and 523 can be spaced apart from each other at positions facing each other or in the range of 120 degrees to 240 degrees with respect to the center of the lens, as ​ illustrated. The guide shafts 521 and 523 can guide the movement of the plurality of lenses along the outside of the plurality of lenses.

[0110] The camera module can include movement guide portions 512A and 512B protruding from the outer side of the holder 512. The movement guide portions 512A and 512B can be coupled to guide shafts 521 and 523, respectively. One or more than two or two or more of the movement guide portions 512A and 512B can be provided on the outer side of the holder 512, for example, two or three. The movement guide portions 512A and 512B can have a through-hole therein, and the guide shafts 521 and 523 can be inserted into the through-hole. The movement guide portions 512A and 512B can have a through-hole, and can guide when at least one of the plurality of guide shafts 521 and 523 moves in the optical axis direction. For example, the first guide shaft 521 provided above the center of the lens module 510 moves in the optical axis direction, the second guide shaft 523 is a fixed shaft at a position below the center of the lens module 510, and supports the movement of the first guide shaft 521, and can support when the lens module 510 slides downward or upward. Here, the connection portion between the first movement guide portion 512A supporting the first guide shaft 521 and the holder 512 has a width (for example, a line width) smaller than the width or diameter of the first movement guide portion 512A and can be connected with a flexible material. Thus, the connection portion between the first movement guide portion 512A and the holder 512 can provide flexibility when the first guide shaft 521 reciprocally moves. As another example, the connection portion can be in contact between the first movement guide portion 512A and the holder 512 in the form of a ball, and can be connected to each other by a ball friction force.

[0111] In addition, the connection portion between the second movement guide portion 512B supporting the second guide shaft 523 and the holder 512 has a width (for example, a line width) smaller than the width or diameter of the second movement guide portion 512B and can be connected with a flexible material. Thus, the connection portion between the second movement guide portion 512B and the holder 512 can provide flexibility when the second guide shaft 523 reciprocally moves. As another example, the connection portion can be in contact between the first movement guide portion 512A and the holder 512 in the form of a ball, and can be connected to each other by a ball friction force. As another example, the first movement guide portion 512A and the second movement guide portion 512B can be formed with an open groove or an open recess portion, and a portion of the guide shafts 521 and 523 exposed to the open groove or the open recess portion enables to swim. The guide shafts 521 and 523 can be provided outside the region where light is incident. That is, the guide shafts 521 and 523 can be provided in a region not exposed to the opening of the housing 501. In addition, the guide shafts 521 and 523 can be arranged within a range not affecting light incident onto the image sensor 553.

[0112] The holder 512 and the movement guide portions 512A and 512B can be provided outside the first and second mirrors 515 and 517. Accordingly, each of the guide shafts 521 and 523 can be individually connected with the first mirror 515, each lens, and the second mirror 517. Accordingly, when ​ the structure shown in FIG. 5A is changed to the structure shown in FIG. 5B, the first guide shaft 521 can move in a direction from the first mirror 515 to the second mirror 517. At this time, the second guide shaft 523 supports the movement of the first and second mirrors 515 and 517 and the plurality of lenses. Accordingly, the upper portion of the lens module 510 and the first and second mirrors 515 and 517 can protrude to the outside of the housing 501 of the mobile terminal, and the centers of the plurality of lenses can be aligned on the same optical axis. ​ On the contrary, when switching from the structure shown in FIG. 5A to the structure shown in FIG. 5C, the first guide shaft 521 can move in a direction from the second mirror 517 to the first mirror 515. At this time, the second guide shaft 523 supports the movement of the first and second mirrors 515 and 517 and the plurality of lenses. Accordingly, the upper portion of the lens module 510 and the first and second mirrors 515 and 517 can be accommodated in the housing 501 of the mobile terminal, and the centers of the plurality of lenses can be aligned on different axes. At this time, since the camera module does not protrude from the surface of the mobile terminal, the lenses can be protected and the appearance design in a non-use mode can be improved. Here, the height difference G5 between the lens module 510 and the upper ends of the first and second mirrors 515 and 517 can be 2 mm or more, for example, in the range of 4 mm to 10 mm in the driving mode and the non-driving mode. Accordingly, the upper portion of the camera module can be exposed during use and not exposed when not in use.

[0113] ​ ​

[0114] The camera module can include a driving unit 130 for transmitting a driving force to at least one of the guide shafts 521 and 523. The driving unit 530 can include at least one of a piezoelectric member, an actuator, and a stepping motor. The driving unit 530 can move at least one guide shaft 521 in the optical axis direction. For example, the piezoelectric member can control the guide shaft 521 that linearly moves according to physical displacement caused by an applied electric field.

[0115] ​​​The driving unit 530 according to an embodiment of the present application can include an actuator including a movable member 531 disposed outside the first mirror 515 and a stator 533 facing the movable member 531. The movable member 531 can be connected to the first guide shaft 521. The movable member 531 can be disposed in a direction perpendicular to a direction in which the first guide shaft 521 extends, and can be pushed up or down in a direction perpendicular to the direction in which the first guide shaft 521 extends with respect to the first guide shaft 521. When the movable member 531 is a magnet, the stator 533 can be a coil. As another example, when the movable member 531 is a coil, the stator 533 can be a magnet. When external power is applied to the driving unit 530, a magnetic field is formed between the driving unit 531 and the movable member 531 according to a polarity of the power applied to the stator 533. At this time, the movable member 531 is connected to the first guide shaft 521, and a force is applied to push the first guide shaft 521 outward from the optical axis due to the magnetic field formed by the power of the first polarity, and in this case, the first guide shaft 521 can move in a direction from the first mirror 515 toward the second mirror 517 (driving mode). In this case, the upper portion of the camera module can protrude through the opening 1D of the housing 501 of the terminal. Accordingly, the first mirror 515 reflects light incident from the object side, and the lens module 510 having a plurality of lenses aligned with the optical axis controls the light incident through the first mirror 515. The light is refracted toward the second mirror 517, and the second mirror 517 can converge the incident light to the image sensor 553. In contrast, a force to pull the first guide shaft 521 in the direction of the optical axis can be applied due to the magnetic field formed by the power of the second polarity. Accordingly, the first guide shaft 521 can move in a direction from the second mirror 517 toward the first mirror 515 (non-driving mode). In this case, the upper portion of the camera module can be accommodated inside the housing 501 of the terminal, and can be disposed below the line 1B parallel to the surface of the housing 501. In this case, the tilt angles of the first mirror 515, each lens, and the second mirror 517 can be the same. Here, as shown in ​ FIG. 6A, the movable member 531 is connected to the first guide shaft 521 in a central region of the lens module 510 overlapping the lens module 510 when viewed, and can be pushed or pulled with respect to the first guide shaft 521 by the magnetic field. As shown in ​ and ​ FIG. 6B, the stator 533 can be fixed to one surface of the support body 541. The support body 541 is disposed such that the stator 533 faces the movable member 531.

[0116] As shown in ​ and ​As shown, the device may include a protective cover 501A, which has a transparent window 501B on the upper part of the camera module. The transparent window 501B is disposed on a first reflector 515 and can transmit incident light to the first reflector 515. The protective cover 501A can support the transparent window 501B and protect the upper part of the camera module. The protective cover 501A can protrude together with the camera module in camera driving mode, and can be positioned at the same level as the upper surface of the housing 501 when the camera is in non-driving mode. For example, as ​ As shown, the protective cover 501A can be placed on top of the holder 512 of the multiple lenses or supported on the first guide shaft 521. Therefore, the protective cover 501A can slide up or down along the movement M5 and M6 of the first guide shaft.

[0117] like ​ and ​ As shown, in the camera module, at least one or both of the first reflector 515A and the second reflector 517 can have a triangular prism shape. However, the prism shape structure can be arranged taking into account the height of the reflectors and interference with the movement of the protective cover 501A or other lenses. For example, when the first reflector 515A is configured in a prism shape, a movable member 531 can be disposed on the rear surface or vertical plane of the first reflector 515A. The movable member 531 can be moved (M5, M6) to slide upward or downward together with the first reflector 515A and the first guide shaft 521.

[0118] like ​ and ​ As shown, the two guide shafts 521 and 523 can be disposed on opposite sides of each other, and the moving guides 512A and 512B can be integrally disposed on the outer retainer 512 of the lens, or can be connected separately. ​ As shown, guide shafts 521, 523, and 525, and the outer guide portions 512A, 512B, and 512C of the retainer 512 are arranged in three different positions, and any one guide shaft 523 arranged on one side of the lens can be spaced more than 120 degrees from the other two guide shafts 523 and 525. These three guide shafts 521, 523, and 525 can be positioned in a region that does not interfere with the incident efficiency of the first reflector 515 and the light collection efficiency to the image sensor 553. Here, the field of view (FOV) of the camera module can be a first angle, and the angle of incidence of the principal ray can be a second angle relative to the optical axis. For example, the first angle can be in the range of 20 to 50 degrees, and the second angle can be approximately half of the first angle. The second angle can be the principal ray angle (CRA). Using the field of view and CRA, the height of the camera module (i.e., the height in the thickness direction of the terminal) can be set by the relationship between the image sensor 553 and the first lens L1 closest to it.

[0119] like ​ As shown in (A), when assuming that the image sensor 553 and the first lens L1 closest to it face each other, Sa can be obtained as S×tan(Sb). Here, S is the distance between the first lens L1 and the image sensor 553, and Sb can be the incident CRA (i.e., CRA 1.0F) on the image sensor 553. ​ As shown in (C), the diagonal length (i.e., SL = 1.0F), that is, the size of the image sensor 553, can be set in the range of 8mm to 16mm.

[0120] like ​ (A) and ​ As shown in (C), the size of the second reflector 517 is set to cover the height H1 of the image sensor 553, and the back focal length BFL can be the sum of the distance Da between the first lens L1 and the second reflector 517 on the path of the incident light L0 and the distance Db between the second reflector 517 and the image sensor 553. The sum of distances (Da+Db) can be equal to or greater than the height H1 of the second reflector 517. When the diagonal length of the first lens L1 is Ll, ​​the thickness is Lt, and the diagonal angle of the first lens is Lq, the height Ld of the first lens L1 can be obtained as S-2sa. S can be obtained as the back focal length (Da+Db).

[0121] Diagonal length Ll passes through get.

[0122] The diagonal angle Lq of the first lens L1 can be obtained asin(Lt / Ll). Therefore, the angle at which the lens module 510, which has the first reflector and the first lens, can be tilted should be less than the height that the module can occupy in the mobile terminal.

[0123] Therefore, with the telephoto lens module as the reference (X 2.5x) and the FOV at 30 degrees, the CRA can be set to 15 degrees. When the image sensor 553 is 1 / 1.7 inches, S is approximately 9.4mm, so H1 can be 9.4mm. In such a camera setup, with an effective focal length (EFL) of 17.54, Sa is 2.5mm and Ld is 6.88. In this case, the height of the lens module is 3mm or 5mm greater than Ld, and can be within a maximum range of 10mm.

[0124] The length of the diagonal L1 can be obtained as Equation 2.

[0125]

[0126] When the limit of the lens module in the mobile terminal is 7mm, Ll must be rotated back to less than 7mm.

[0127]

[0128] The finally required Aθ is obtained as Lq+Pq, and Aθ can be an angle in which the lens module can be tilted.

[0129] Therefore,

[0130] In Equations 3, 4, when Lt is 2.8 mm as in the example, and the lens module height H is 7 mm, Lq=15.6 degrees, Pq=47.6 degrees, Aθ can be obtained as 63.2 degrees. Thus, the overall effective height can be reduced to 7 mm, which is less than 10 mm. Thus, the lens height or diameter can be reduced by 35% or less, for example, in the range of 25% to 35% with respect to the total height. That is, the height of the lens module can be reduced by 30% through the operation before or after tilting. A part of the camera module can protrude only during use and can not protrude during non-use outside the housing 501 of the mobile terminal such as a smartphone. Thus, in the non-use mode of the camera, the problem that a part of the lens module of the camera device protrudes outside the smartphone can be improved, thus facilitating portability and can improve the appearance design. The surface of the camera module can also be protected from damage.
