[0002] This application claims the benefit of priority from Korean Patent Application No. 10-2024-0047706 filed on April 9, 2024, in the Korean Intellectual Property Office, and Korean Patent Application No. 10-2023-0151177 filed on November 3, 2023, in the Korean Intellectual Property Office, the disclosures of which are incorporated herein by reference in their entirety for all purposes. Technical Field

[0003] The following description relates to a camera module. Background Art

[0004] Portable electronic devices include camera modules. For example, portable electronic devices such as, but not limited to, portable phones, laptops, and the like may typically include one or more camera modules. As photography and video recording using portable electronic devices become more common, there is a demand for improved camera module performance. However, since small portable terminals generally have a relatively thin thickness, it may be difficult to mount a camera module with high performance and high resolution. For example, in order to reduce or miniaturize a telephoto camera module with a long focal length, the image sensor package should also be small. However, for high-resolution imaging and photography, an image sensor or image sensor package of sufficient size is required. Utility Model Content

However, the electronic devices on which the camera module may be mounted are not limited to the aforementioned devices. As an example, the camera module may be mounted on any portable electronic device such as a portable game console.

[0049] A camera module according to the first aspect may include a first lens group, a second lens group, a first optical path conversion unit, a second optical path conversion unit, an image sensor, and a first driving unit. In the camera module according to the first aspect, the first lens group may include one or more lenses.

In the camera module according to the first aspect, the second lens group may include one or more lenses. For example, the second lens group may include one or more lenses arranged along a second optical axis. In this example, the second optical axis may be in a direction intersecting the first optical axis. In the camera module according to the first aspect, the first optical path conversion unit may be configured to reflect light incident through the first lens group toward the second lens group. In the camera module according to the first aspect, the second optical path conversion unit may be configured to reflect light incident through the second lens group toward the image sensor. For example, the second optical path conversion unit may reflect light incident along the second optical axis of the second lens group toward a third optical axis of the image sensor. In this example, the third optical axis may be configured to form an acute angle with the first optical axis. In the camera module according to the first aspect, the first driving unit may drive one or more of the first optical path conversion unit and the image sensor.

[0050] The camera module according to the second aspect may include a first lens group, a second lens group, a first optical path conversion unit, a second optical path conversion unit, an image sensor, and a first drive unit. In the camera module according to the second aspect, the first lens group, the first optical path conversion unit, the second lens group, the second optical path conversion unit, and the image sensor may be arranged sequentially along an optical axis. Furthermore, in the camera module according to the second aspect, the image sensor may be arranged so as to form an acute angle with respect to an incident surface of the second optical path conversion unit.

[0051] Hereinafter, various embodiments will be described with reference to the accompanying drawings.

[0052] First, refer to Figures 1 to 4D An exemplary camera module according to a first embodiment is described.

[0053] The camera module 10 according to the first embodiment may include a first lens group 100, a first optical path conversion unit 200, a second lens group 300, a second optical path conversion unit 400, and an image sensor package 500. However, the configuration of the camera module 10 according to the first embodiment is not limited to the above elements. As an example, the camera module 10 may further include a first driving unit 600 that drives the first optical path conversion unit 200.

[0054] The first lens group 100, the first optical path conversion unit 200, the second lens group 300, the second optical path conversion unit 400, and the image sensor package 500 may be arranged sequentially along the optical axis. In an example, the first optical path conversion unit 200 may be disposed on the image side of the first lens group 100, the second lens group 300 may be disposed on the image side of the first optical path conversion unit 200, the second optical path conversion unit 400 may be disposed on the image side of the second lens group 300, and the image sensor package 500 may be disposed on the image side of the second optical path conversion unit 400.

[0055] The first lens group 100 may include one or more lenses arranged in sequence along the first optical axis C1. For example, the first lens group 100 may include a first lens having a refractive power. However, the number of lenses constituting the first lens group 100 is not limited to one lens. The first lens group 100 or the first lens may have a predetermined refractive power. For example, the first lens group 100 or the first lens may have a positive refractive power. The first lens group 100 or the first lens may have an overall meniscus shape. For example, the object-side surface of the first lens disposed at the front end of the first lens group 100 may be convex, and the image-side surface of the lens disposed at the rear end of the first lens group 100 may be concave. The first lens group 100 may include lenses of a predetermined size. For example, the maximum diameter of the first lens disposed at the front end of the first lens group 100 may be greater than the maximum length (horizontal length or vertical length of the incident surface) of the first optical path conversion unit 200.

[0056] The first optical path conversion unit 200 can be configured to reflect light incident along the first optical axis C1 of the first lens group 100 onto the second optical axis C2 of the second lens group 300. For example, the first optical path conversion unit 200 can be configured in the form of a prism that totally reflects light incident along the first optical axis C1 in the direction of the second optical axis C2. However, the form of the first optical path conversion unit 200 is not limited to a prism. For example, the first optical path conversion unit 200 can be replaced with a mirror.

[0057] The first optical path conversion unit 200 can be configured as follows Figures 2A to 2C The unique shape shown in .

[0058] As an example, the first optical path conversion unit 200 may be configured to have positive refractive power. As a detailed example, the first optical path conversion unit 202 according to the first modification may have Figure 2AThe convex shape of the exit surface 230 shown in FIG. The convex shape of the exit surface 230 can be formed by integrally combining a conventional prism and a plano-convex lens, or by integrally molding a prism and a plano-convex lens. As another example, the first optical path conversion unit 200 can be configured such that the incident surface 210 and the exit surface 230 or the emission surface 230 can be configured to have different areas.

[0059] As a detailed example, in the first optical path conversion unit 204 according to the second modification, as shown in FIG. Figure 2B As shown in , the exit surface 230 may be formed to extend longitudinally along the direction of the first optical axis C1, so that the incident surface 210 has an area larger than that of the exit surface 230. As another example, Figure 2C As shown in , the first optical path conversion unit 206 may be formed in a manner that an edge or corner of the exit surface 230 is chamfered.

[0060] The second lens group 300 may include one or more lenses arranged sequentially along the second optical axis C2. As an example, the second lens group 300 may include a second lens and a third lens arranged sequentially along the second optical axis C2. The second lens and the third lens may each have positive or negative refractive power. As a detailed example, the second lens may have positive refractive power and the third lens may have negative refractive power. However, the number of lenses comprising the second lens group 300 and the refractive powers of the lenses are not limited to the above. For example, the second lens group 300 may consist of three or more lenses.

[0061] The second optical path conversion unit 400 may be configured to reflect light incident along the second optical axis C2 toward the image sensor of the image sensor package 500. For example, the second optical path conversion unit 400 may include two or more reflective surfaces so that light incident along the second optical axis C2 may be incident along a third optical axis C3 of the image sensor.

[0062] Will refer to Figure 3 The second optical path conversion unit 400 according to one aspect is described in detail.

[0063] The second optical path conversion unit 400 may include an incident surface 410, a first reflective surface 420, and a second reflective surface 430. The second optical path conversion unit 400 may have an integrally formed reflective surface and an exit surface. For example, the first reflective surface 420 of the second optical path conversion unit 400 may be a reflective surface on which light is reflected and an exit surface on which light is emitted.

[0064] The second optical path conversion unit 400 can be configured to obtain both total reflection and specular reflection of light. As an example, the first reflective surface 420 of the second optical path conversion unit 400 can be configured to provide total reflection of light, and the second reflective surface 430 of the second optical path conversion unit 400 can be configured to provide specular reflection of light. As a detailed example, the first incident angle θ1 of the first reflective surface 420 is greater than the critical angle of the first reflective surface 420, and the second incident angle θ2 of the second reflective surface 430 can be less than the critical angle of the second reflective surface 430. The first reflective surface 420 and the second reflective surface 430 can be arranged in a predetermined shape. For example, the angle θ between the first reflective surface 420 and the second reflective surface 430 can be 16 degrees to 32 degrees. As a detailed example, the angle θ between the first reflective surface 420 and the second reflective surface 430 can be 30 degrees or 18 degrees.

[0065] The second optical path conversion unit 400 can be configured to provide multiple internal reflections. In detail, the second optical path conversion unit 400 can be configured to perform an even number of internal reflections. For example, the second optical path conversion unit 400 can be configured to perform two or four internal reflections. The number (N) of internal reflections of the second optical path conversion unit 400 and the angle θ between the first reflective surface 420 and the second reflective surface 430 can satisfy the following conditional expression.

[0066] θ=90 / (2n+1), 2n=N

[0067] In the above conditional expressions, n is a positive integer. For example, when the number of internal reflections of the second optical path conversion unit 400 is 2, the angle θ is 30 degrees. As another example, when the number of internal reflections of the second optical path conversion unit 400 is 4, the angle θ is 18 degrees. The number of internal reflections of the second optical path conversion unit 400 may be 6 or greater. However, it is more preferred that the number of internal reflections of the second optical path conversion unit 400 does not exceed 4. To further explain, in the example where the number of internal reflections of the second optical path conversion unit 400 increases to 6 or greater, the angle of incidence θ decreases to 12.9 degrees or less, and the amount of light incident on the second optical path conversion unit 400 also decreases. Therefore, the problem of rapid deterioration of the resolution of the camera module may occur. Therefore, it is more preferred that the number of internal reflections of the second optical path conversion unit 400 is 2 or 4.

[0068] The image sensor package 500 may be configured to include an image sensor (not shown). For example, the image sensor may be provided on one side of the image sensor package 500 to convert light incident through the second optical path conversion unit 400 into an electrical signal. The image sensor package 500 may be provided to face one side of the second optical path conversion unit 400. As an example, the image sensor package 500 may be provided to face the first reflective surface 420 of the second optical path conversion unit 400.

[0069] The first drive unit 600 can be configured to enable optical image stabilization (OIS) of the camera module 10. In this embodiment, the first drive unit 600 can be configured to move the first optical path conversion unit 200 in a direction intersecting the first optical axis C1. As an example, the first drive unit 600 can be configured to move the first optical path conversion unit 200 in a first direction and a second direction intersecting the first optical axis C1. As another example, the first drive unit 600 can be configured to move the first optical path conversion unit 200 in a first direction intersecting the first optical axis C1 and rotate the first optical path conversion unit 200 based on the first optical axis C1.

[0070] Will refer to Figures 4A to 4D The combined structure of the first optical path conversion unit 200 and the first driving unit 600 is described in detail.

[0071] like Figure 4A As shown in , the first driving unit 600 may be configured to partially contact or couple with the first optical path conversion unit 200. For example, the first driving unit 600 may be configured to support at least one of a reflective surface and a side surface of the first optical path conversion unit 200.

[0072] like Figure 4B and Figure 4C As shown in FIG, the first drive unit 600 may include a movable body 610, a first drive portion 620, and a second drive portion 630. However, the configuration of the first drive unit 600 is not limited to the above components. For example, the first drive unit 600 may further include ball bearings 642 and 644 to enable smooth movement of the first optical path conversion unit 200 or the movable body 610. As another example, the first drive unit 600 may further include Hall sensors 652 and 654 for detecting the position of the movable body 610.

[0073] The movable body 610 may be composed of multiple components or elements. As an example, the movable body 610 may be composed of a first movable body 612 and a second movable body 614. However, the configuration of the movable body 610 is not limited to the first movable body 612 and the second movable body 614. For example, the movable body 610 may be composed of three or four components as needed. The first movable body 612 may be configured to support the first optical path conversion unit 200. As an example, a receiving portion 6122 on which the first optical path conversion unit 200 can be placed may be formed in the first movable body 612. The second movable body 614 may be configured to support the first movable body 612. The second movable body 614 may be disposed in the housing 12 of the camera module 10. For example, the second movable body 614 may be disposed on the inner bottom of the housing 12. The first movable body 612 and the second movable body 614 may be configured to rotate or move separately. As an example, the first movable body 612 is configured to rotate or move in one direction while being coupled to the second movable body 614 , and the second movable body 614 may be configured to rotate or move in a different direction while being disposed in the housing 12 .

[0074] The first drive section 620 can be configured to drive the first movable body 612. For example, the first drive section 620 can rotate the first movable body 612 in a direction intersecting the first optical axis C1 and the second optical axis C2. The first drive section 620 can include a first drive magnet 622 and a first drive coil 624. However, the configuration of the first drive section 620 is not limited to the above components. The first drive magnet 622 can be formed in the first movable body 612. For example, the first drive magnet 622 can be formed on the rear surface of the first movable body 612 facing one surface of the housing 12. The first drive coil 624 can be formed in the housing 12. For example, the first drive coil 624 can be formed on the inner surface of the housing 12 facing the first drive magnet 622. The first drive magnet 622 and the first drive coil 624 arranged in this manner can rotate or drive the first movable body 612 in a direction based on the magnetic force generated by the first drive magnet 622 and the first drive coil 624. In an example, the first drive coil 624 can include multiple coils.

[0075] The second driving part 630 can be configured to drive the second movable body 614. For example, the second driving part 630 can rotate the second movable body 614 around the first optical axis C1. The second driving part 630 may include a second driving magnet 632 and a second driving coil 634. However, the configuration of the second driving part 630 is not limited to the above-mentioned components. The second driving magnet 632 can be formed in the second movable body 614. For example, the second driving magnet 632 can be formed on the lower surface of the bottom of the second movable body 614 facing the housing 12. The second driving coil 634 can be formed in the housing 12. For example, the second driving coil 634 can be formed on the bottom of the housing 12 facing the second driving magnet 632. The second driving magnet 632 and the second driving coil 634 arranged in this manner can rotate or drive the second movable body 614 in one direction by the magnetic force generated between the second driving magnet 632 and the second driving coil 634.

[0076] The ball bearings 642 and 644 can be configured to enable smooth operation of the first movable body 612 and the second movable body 614. As an example, the first ball bearing 642 can be provided between the first movable body 612 and the second movable body 614, and the second ball bearing 644 can be provided between the second movable body 614 and the housing 12. For reference, grooves 612h, 614h, and 12h for receiving the ball bearings 642 and 644 can be formed in the first movable body 612, the second movable body 614, and the housing 12, respectively. On the other hand, in an example, at least some of the grooves 612h, 614h, and 12h can have a polygonal cross-sectional shape instead of a circular shape to significantly reduce the contact area with the ball bearings 642 and 644.

[0077] The Hall sensors 652 and 654 may be configured to detect the positions of the first movable body 612 and the second movable body 614. For example, the first Hall sensor 652 may be disposed between the coils of the first drive coil 624 or adjacent to the first drive coil 624 and configured to detect the movement of the first movable body 612, and the second Hall sensor 654 may be disposed on one side of the second drive coil 634 and configured to detect the movement of the second movable body 614. However, the arrangement of the Hall sensors 652 and 654 is not limited to the above-described positions.

[0078] The first driving unit 600 may further include a component that prevents the first movable body 612 from separating.

[0079] In the camera module 10 configured as described above, the first optical path conversion unit 200 and the second optical path conversion unit 400 can be used to converge straight optical paths into a limited space. Furthermore, since the camera module 10 according to this embodiment can perform optical image stabilization based on the first drive unit 600, high-resolution image quality is possible. Furthermore, in the camera module 10 according to this embodiment, the image sensor package 500 can be arranged relatively wide along the diagonal direction of the second optical path conversion unit 400, making it easy to mount a large image sensor and electronic components necessary for high-resolution image quality.

[0129] The first driving unit 601 may further include a component that prevents the first movable body 612 from separating. For example, the first driving unit 601 may include a pair of magnetic bodies 662 and 664 configured to generate an attractive force between the first movable body 612 and the second movable body 614. The first magnetic body 662 may be provided on one side of the first movable body 612 (see FIG. Figure 12C and Figure 12D ), and the second magnetic body 664 may be provided on one side of the second movable body 614 (see Figure 12B and Figure 12D ). The magnetic bodies 662 and 664 configured in this manner can suppress separation of the first movable body 612 and the second movable body 614 by attracting each other.

[0130] Will refer to Figure 13A and Figure 13B The first driving unit 801 is described.

[0131] The first driving unit 801 may be formed in the image sensor package 500. In one example, the first driving unit 801 may be formed in a partial region of the image sensor package 500, or may be integrally formed with the image sensor package 500. In another example, the first driving unit 801 may be configured to accommodate the image sensor package 500. The first driving unit 801 may include a movable body 812, a fixed body 814, a first driving portion 820, and a second driving portion 830. However, the configuration of the first driving unit 801 is not limited to the above components.

[0132] The movable body 812 can be configured to be combined with the image sensor package 500 or the image sensor 510. For example, the movable body 812 can be coupled to the image sensor package 500, or can be configured to accommodate the image sensor 510. The movable body 812 can be configured to be electrically connected to the image sensor package 500 or the image sensor 510. For example, the movable body 812 can be configured in the form of a printed circuit board. However, the form of the movable body 812 is not limited to a printed circuit board. The fixed body 814 can be configured to accommodate the movable body 812. For example, a receiving portion 8142 can be formed inside the fixed body 814 to accommodate the movable body 812 and the image sensor package 500. Similar to the movable body 812, the fixed body 814 can be configured to be electrically connected to the image sensor package 500 or the image sensor 510. For example, the fixed body 814 can be configured in the form of a printed circuit board. However, the form of the fixed body 814 is not limited to a printed circuit board.

[0133] The first driving portion 820 may include a first driving magnet 822 and a first driving coil 824. However, the configuration of the first driving portion 820 is not limited to the above-mentioned components or elements. The first driving magnet 822 and the first driving coil 824 may be arranged to face each other or be adjacent to each other. In an example, the first driving magnet 822 may be formed in the movable body 812, and the first driving coil 824 may be formed in the fixed body 814. In another example, the first driving magnet 822 may be formed on the fixed body 814, and the first driving coil 824 may be formed on the movable body 812. The first driving portion 820 configured in this manner can move the image sensor 510 or the image sensor package 500 in a first direction intersecting the third optical axis C3 based on the magnetic force generated between the first driving magnet 822 and the first driving coil 824.

[0134] The second driving portion 830 may include a second driving magnet 832 and a second driving coil 834. However, the configuration of the second driving portion 830 is not limited to the above-mentioned components or elements. The second driving magnet 832 and the second driving coil 834 may be arranged to face each other, or may be arranged to be adjacent to each other. In an example, the second driving magnet 832 may be formed in the movable body 812, and the second driving coil 834 may be formed in the fixed body 814. In another example, the second driving magnet 832 may be formed on the fixed body 814, and the second driving coil 834 may be formed on the movable body 812. The second driving portion 830 configured in this manner can move the image sensor 510 or the image sensor package 500 in a second direction that intersects the third optical axis C3 based on the magnetic force generated between the second driving magnet 832 and the second driving coil 834.

[0135] In this example, the drive sections 820 and 830 according to this embodiment may be composed of a drive magnet and a drive coil. However, this is merely an example, and the configuration of the drive sections 820 and 830 may be changed within a range that allows the movable body 812 to move in a direction intersecting the third optical axis C3. For example, in a modified form of the embodiment, the drive sections 820 and 830 may be changed to a shape memory alloy, a piezoelectric member, or the like.

[0136] The camera module 50 configured as described above can implement a telephoto imaging optical system with a long focal length. Furthermore, in the camera module 50 according to this embodiment, the multiple first drive units 601 and 801 can simultaneously or selectively drive at least one or more of the first optical path conversion unit 200 and the image sensor package 500, thereby performing fast and precise optical image stabilization. Furthermore, in the camera module 50 according to this embodiment, the image sensor package 500 can be arranged relatively wide in the diagonal direction of the second optical path conversion unit 400, thereby easily mounting a large image sensor and electronic components necessary for achieving high resolution.

[0137] Next, we will refer to Figure 14 and Figure 15 Another form of the camera module according to the third embodiment is described.

[0138] In this example, in the camera module 60 according to this form, components that are the same as those in the above-described embodiment are basically denoted by the same reference numerals as those in the above-described embodiment, and detailed descriptions of these components will be omitted.

[0139] The camera module 60 according to this form differs from the camera module 50 according to the above embodiment in that the camera module 60 further includes a second driving unit 700. Specifically, the camera module 60 according to this form may further include a second driving unit 700 that drives the second lens group 300 in the direction of the second optical axis C2.

[0140] Will refer to Figure 15 The configuration of the second driving unit 700 is described.

[0141] The second drive unit 700 may include a movable body 710, a drive magnet 720, a drive coil 730, a detection sensor 740, and a circuit board 750. However, the configuration of the second drive unit 700 is not limited to the above components. In the example, the second drive unit 700 further includes a ball bearing 760.

[0142] The movable body 710 can be disposed inside the housing 62. For example, the movable body 710 can be disposed while maintaining a predetermined distance from the bottom of the housing 62, or can be disposed so as to partially contact the bottom of the housing 62. The movable body 710 can be configured to accommodate the second lens group 300. In an example, a receiving portion 712 can be formed in the movable body 710 to accommodate the second lens group 300. The movable body 710 can be configured to move in the direction of the second optical axis C2. Specifically, the movable body 710 can move along the second optical axis C2 while being combined with the second lens group 300. In an example, a ball bearing 760 can be disposed between the movable body 710 and the housing 62 to allow the movable body 710 to move smoothly. Specifically, the ball bearing 760 can be disposed between the groove 62h of the housing 62 and the groove 714h of the movable body 710.

[0143] The driving magnet 720 and the driving coil 730 can be formed in the movable body 710 and the housing 62, respectively. For example, the driving magnet 720 can be formed on both sides of the movable body 710, and the driving coil 730 can be disposed in the through-hole 62c of the housing 62 using the circuit board 750 as a medium. The driving magnet 720 and the driving coil 730 can be arranged so as to face each other. The driving magnet 720 and the driving coil 730 configured in this manner can move the second lens group 300 and the movable body 710. For example, the driving magnet 720 and the driving coil 730 can move the second lens group 300 and the movable body 710 in the direction of the second optical axis C2. For reference, the driving magnet 720 is preferably formed to be elongated in the direction of the second optical axis C2 so that the driving magnet 720 can interact with the driving coil 730 even when the movable body 710 changes position.

[0144] The camera module 60 configured as above includes all the features of the above-described camera module 50 , and has a feature of being able to adjust the focal length of the camera module through the second driving unit 700 .

[0145] As explained above, the camera module according to the embodiment may be mounted on a small portable terminal.

[0146] Furthermore, the camera module according to the embodiment is capable of high-resolution imaging and photographing while having a long focal length.
