Description

Technical Field

[0001] The present invention relates to optical imaging technology, and particularly to an optical camera lens group, an image pickup module, and an electronic device. Background Art

[0002] Currently, although four - or five - element optical camera lens groups can meet the requirements of miniaturization, the refractive power configuration of their lenses is unbalanced, which easily causes excessive off - axis aberration and is difficult to correct, resulting in poor efficiency of the electronic photosensitive element in receiving the light emitted by an object and affecting the imaging quality. Summary of the Invention

[0003] Aiming at the technical problem that the four - or five - element optical camera lens group in the prior art cannot simultaneously meet the usage requirements of both the optical total length and the imaging quality, an optical camera lens group, an image pickup module, and an electronic device are provided in an embodiment of the present invention.

[0004] The optical camera lens group according to the embodiment of the present invention sequentially includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens from the object side to the image side. The first lens has a positive refractive power, and the image side surface of the first lens is concave at the optical axis; the object side surface of the second lens is convex at the optical axis; the object side surface of the third lens is convex at the optical axis; the fifth lens has a positive refractive power, and both the object side surface and the image side surface of the fifth lens are aspherical surfaces, and at least one inflection point is provided on the object side surface of the fifth lens; the sixth lens has a negative refractive power, the image side surface of the sixth lens is concave at the optical axis, both the object side surface and the image side surface of the sixth lens are aspherical surfaces, and at least one inflection point is provided on at least one of the object side surface and the image side surface of the sixth lens; the optical camera lens group satisfies the following conditional formula: 5 < f / CT5 < 12; where f is the focal length of the optical camera lens group, and CT5 is the central thickness of the fifth lens on the optical axis.

[0005] The optical camera lens group according to the embodiment of the present invention can ensure the miniaturization of the optical camera lens group while obtaining excellent imaging quality. In addition, by providing an aperture on the object side surface of the first lens, the size of the relative aperture is enlarged, and the light input is increased, which is beneficial to obtaining a display image with less noise and better image quality. Further, the optical camera lens group satisfies the conditional formula 5 < f / CT5 < 12, which can reasonably control the astigmatism of the optical camera lens group and obtain good imaging quality in the off - axis field of view.

[0006] In some embodiments, the optical camera lens group further satisfies the following conditional formula: 0.5 < |f1 / f6| < 2; where f1 is the focal length of the first lens, and f6 is the focal length of the sixth lens.

[0007] When the optical camera lens group satisfies the conditional expression 0.5 < |f1 / f6| < 2, the first lens provides positive refractive power and the sixth lens provides negative refractive power, which can reasonably distribute the positive and negative refractive powers of the optical camera lens group, effectively balance and control the spherical aberration of the optical camera lens group, reduce the sensitivity of the optical camera lens group, and improve the imaging quality of the optical camera lens group.

[0008] In some embodiments, the optical camera lens group further satisfies the following conditional expression: -3 < f2 / f < 1.5; where f2 is the focal length of the second lens.

[0009] When the optical camera lens group satisfies the conditional expression -3 < f2 / f < 1.5, the positive and negative refractive powers of the optical camera lens group can be reasonably distributed, the aberration of the optical camera lens group can be corrected, and the sensitivity of the optical camera lens group can be reduced.

[0010] In some embodiments, the optical camera lens group further satisfies the following conditional expressions: 1.4 < nd2 < 1.7, 15 < vd2 < 60; and / or 1.4 < nd3 < 1.7, 15 < vd3 < 60; and / or 1.4 < nd4 < 1.7, 15 < vd4 < 60; and / or 1.4 < nd5 < 1.7, 15 < vd5 < 60; where nd2 is the refractive index of the second lens, vd2 is the Abbe number of the second lens; nd3 is the refractive index of the third lens, vd3 is the Abbe number of the third lens; nd4 is the refractive index of the fourth lens, vd4 is the Abbe number of the fourth lens; nd5 is the refractive index of the fifth lens, vd5 is the Abbe number of the fifth lens.

[0011] When the optical camera lens group satisfies the conditional expressions 1.4 < nd2 < 1.7, 15 < vd2 < 60; and / or 1.4 < nd3 < 1.7, 15 < vd3 < 60; and / or 1.4 < nd4 < 1.7, 15 < vd4 < 60; and / or 1.4 < nd5 < 1.7, 15 < vd5 < 60, by reasonably selecting the lens materials, the optical camera lens group can effectively eliminate chromatic aberration and improve the imaging quality of the optical camera lens group.

[0012] In some embodiments, the optical camera lens group further satisfies the following conditional expression: Imgh / TTL ≥ 0.5; where Imgh is half of the maximum imaging height of the optical camera lens group, and TTL is the distance from the object side of the first lens to the imaging plane along the optical axis.

[0013] When the optical camera lens group satisfies the conditional expression Imgh / TTL ≥ 0.5, it can meet both the user's high pixel requirements for the optical camera lens group and the miniaturization requirements.

[0014] In some embodiments, the optical camera lens group further satisfies the following conditional formula: Imgh / TTL≥0.7; where Imgh is half of the maximum imaging height of the optical camera lens group, and TTL is the distance from the object side surface of the first lens to the imaging surface along the optical axis.

[0015] Compared with an optical camera lens group that satisfies the conditional formula Imgh / TTL≥0.5, the optical camera lens group that satisfies the conditional formula Imgh / TTL≥0.7 can further meet the user's high-pixel requirements for the optical camera lens group and can further meet the miniaturization requirements.

[0016] In some embodiments, the optical camera lens group further satisfies the following conditional formula: -5<(R8+R9) / (R8-R9)<260; where R8 is the curvature radius of the object side surface of the fourth lens, and R9 is the curvature radius of the image side surface of the fourth lens.

[0017] When the optical camera lens group satisfies the conditional formula -5<(R8+R9) / (R8-R9)<260, by reasonably restricting the relationship between the object side surface and the image side surface of the fourth lens, the optical camera lens group can effectively distribute the optical deflection angles borne by the lenses and simultaneously improve the astigmatism of the off-axis field of view.

[0018] In some embodiments, the optical camera lens group further satisfies the following conditional formula: -7<R12 / R13<3.5; where R12 is the curvature radius of the object side surface of the sixth lens, and R13 is the curvature radius of the image side surface of the sixth lens.

[0019] When the optical camera lens group satisfies the conditional formula -7<R12 / R13<3.5, by adjusting the curvature radius of the sixth lens, the spherical aberration and astigmatism of the optical camera lens group can be effectively corrected, thereby improving the imaging quality of the optical camera lens group.

[0020] In some embodiments, the optical camera lens group further satisfies the following conditional formula: 0.5<|f2 / R4|<2; where f2 is the focal length of the second lens, and R4 is the curvature radius of the object side surface of the second lens.

[0021] When the optical camera lens group satisfies the conditional formula 0.5<|f2 / R4|<2, the aberration generated by the optical camera lens group can be balanced, and at the same time, the high-order aberration generated by the second lens can be further corrected, improving the imaging quality.

[0022] In some embodiments, the optical camera lens group further satisfies the following conditional formula: -5<R6 / f3<2.0; where R6 is the curvature radius of the object side surface of the third lens, and f3 is the focal length of the third lens.

[0023] When the optical camera lens group satisfies the conditional formula -5 < R6 / f3 < 2.0, it can balance aberrations such as astigmatism and distortion generated by the optical camera lens group, and at the same time can further correct the high-order aberrations generated by the third lens.

[0024] In some embodiments, the optical camera lens group further satisfies the following conditional formula: (CT1 + CT2 + CT3) / TTL < 0.3; where CT1 is the central thickness of the first lens on the optical axis, CT2 is the central thickness of the second lens on the optical axis, CT3 is the central thickness of the third lens on the optical axis, and TTL is the distance from the object side surface of the first lens to the imaging surface on the optical axis.

[0025] When the optical camera lens group satisfies the conditional formula (CT1 + CT2 + CT3) / TTL < 0.3, the first lens, the second lens, and the third lens have a reasonable thickness configuration, which is beneficial to reducing the sensitivity of the optical camera lens group and shortening the overall optical length of the optical camera lens group.

[0026] In some embodiments, the optical camera lens group further satisfies the following conditional formula: 12 < f45 / CT34 < 85; where f45 is the combined focal length of the fourth lens and the fifth lens, and CT34 is the air gap between the third lens and the fourth lens on the optical axis.

[0027] When the optical camera lens group satisfies the conditional formula 12 < f45 / CT34 < 85, the refractive power of the optical camera lens group is reasonably distributed, the imaging quality is improved, and the size of the optical camera lens group is reduced.

[0028] The imaging module according to the embodiment of the present invention includes the optical camera lens group and the photosensitive element described in any one of the above embodiments. The photosensitive element is disposed on the image side of the optical camera lens group.

[0029] The imaging module according to the embodiment of the present invention can ensure the miniaturization of the optical camera lens group while obtaining excellent imaging quality. In addition, the optical camera lens group enlarges the size of the relative aperture and increases the light input amount through the aperture disposed on the object side surface of the first lens, which is beneficial to obtaining a display image with less noise and better image quality. Further, when the optical camera lens group satisfies the conditional formula 5 < f / CT5 < 12, the astigmatism of the optical camera lens group can be reasonably controlled, and good imaging quality can be obtained in the off-axis field.

[0030] The electronic device according to the embodiment of the present invention includes a housing and the imaging module described in the above embodiment. The imaging module is mounted on the housing.

[0031] The electronic device according to the embodiment of the present invention can ensure the miniaturization of the optical camera lens group while obtaining excellent imaging quality. In addition, the relative aperture size is enlarged by the aperture disposed on the object side of the first lens in the optical camera lens group, and the amount of incident light is increased, which is beneficial to obtaining a display image with less noise and better image quality. Further, the optical camera lens group satisfies the conditional formula 5 < f / CT5 < 12, which can reasonably control the astigmatism of the optical camera lens group and obtain good imaging quality in the off-axis field. And the housing can protect the image pickup module.

The first lens element L1 has positive refractive power. The fifth lens element L5 has positive refractive power. The sixth lens element L6 has negative refractive power.

[0064] The aperture STO can be an aperture stop or a field stop. The embodiments of the present invention are described using an aperture stop as an example.

[0066] The optical imaging lens group 10 of the embodiment of the present invention satisfies the following conditional formula: 5 < f / CT5 < 12; where f is the focal length of the optical imaging lens group 10, and CT5 is the central thickness of the fifth lens L5 on the optical axis. That is to say, f / CT5 can be any value within the interval (5, 12). For example, this value can be 5.636, 5.648, 6.605, 7.104, 7.785, 7.882, 7.987, 8.485, 8.681, 10.258, 10.699, and so on.

[0067] The optical imaging lens group 10 of the embodiment of the present invention can ensure the miniaturization of the optical imaging lens group 10 while obtaining excellent imaging quality. In addition, the diaphragm STO provided on the object side S1 of the first lens L1 of the optical imaging lens group 10 expands the size of the relative aperture and increases the light input amount, which is beneficial to obtaining a display image with less noise and better image quality. Further, the optical imaging lens group 10 satisfies the conditional formula 5 < f / CT5 < 12, which can reasonably control the astigmatism of the optical imaging lens group 10 and obtain good imaging quality for off-axis fields.

[0068] In some embodiments, the optical camera lens group 10 satisfies the following conditional formula: 0.5 < |f1 / f6| < 2; where f1 is the focal length of the first lens L1, and f6 is the focal length of the sixth lens L6.

[0069] When the optical camera lens group 10 satisfies the conditional formula 0.5 < |f1 / f6| < 2, the first lens L1 provides positive refractive power, and the sixth lens L6 provides negative refractive power. By reasonably distributing the positive and negative refractive powers of the optical camera lens group 10, the spherical aberration of the optical camera lens group 10 can be effectively balanced and controlled, the sensitivity of the optical camera lens group 10 can be reduced, and the imaging quality of the optical camera lens group 10 can be improved.

[0070] In some embodiments, the optical camera lens group 10 satisfies the following conditional formula: -3 < f2 / f < 1.5; where f2 is the focal length of the second lens L2.

For example, this value can be 1.517, 1.535, 1.545, 1.634, 1.636, 1.639, 1.661, 1.678, etc.; vd2 can be any value within the interval (15, 60).

For example, this value can be 1.517, 1.535, 1.545, 1.634, 1.636, 1.639, 1.661, 1.678, etc.; vd3 can be any value within the interval (15, 60). For example, this value can be 19.2, 20.4, 24.0, 55.9, 64.2, etc.; or, 1.4 < nd2 < 1.7, 15 < vd2 < 60; and 1.4 < nd3 < 1.7, 15 < vd3 < 60; that is to say, nd2 and nd3 can be any value within the interval (1.4, 1.7). For example, this value can be 1.517, 1.535, 1.545, 1.634, 1.636, 1.639, 1.661, 1.678, etc.; vd2 and vd3 can be any value within the interval (15, 60). For example, this value can be 19.2, 20.4, 24.0, 55.9, 64.2, etc.; or, 1.4 < nd2 < 1.7, 15 < vd2 < 60; 1.4 < nd3 < 1.7, 15 < vd3 < 60; 1.4 < nd4 < 1.7, 15 < vd4 < 60; and 1.4 < nd5 < 1.7, 15 < vd5 < 60; that is to say, nd2, nd3, nd4, and nd5 can be any value within the interval (1.4, 1.7). For example, this value can be 1.517, 1.535, 1.545, 1.634, 1.636, 1.639, 1.661, 1.678, etc.; vd2, vd3, vd4, and vd5 can be any value within the interval (15, 60). For example, this value can be 19.2, 20.4, 24.0, 55.9, 64.2, etc.; To save space, other combinations of the above conditional expressions are not listed here one by one. This is only for exemplary illustration and not a limitation on the embodiments of the present invention.

[0073] When the optical camera lens group 10 satisfies the conditional expressions 1.4 < nd2 < 1.7, 15 < vd2 < 60; and / or 1.4 < nd3 < 1.7, 15 < vd3 < 60; and / or 1.4 < nd4 < 1.7, 15 < vd4 < 60; and / or 1.4 < nd5 < 1.7, 15 < vd5 < 60, by reasonably selecting the lens materials, the optical camera lens group 10 can effectively eliminate the chromatic aberration and improve the imaging quality of the optical camera lens group 10.

[0074] In some embodiments, the optical camera lens group 10 satisfies the following conditional expression: Imgh / TTL ≥ 0.5; where Imgh is half of the maximum imaging height of the optical camera lens group 10, and TTL is the distance from the object side surface S1 of the first lens L1 to the imaging surface S15 along the optical axis. That is to say, Imgh / TTL can be any value greater than or equal to 0.5. For example, this value can be 0.500, 0.590, 0.613, 0.697, 0.709, 0.713, 0.739, 0.756, 0.769, 0.817, and so on.

[0075] When the optical camera lens group 10 satisfies the conditional expression Imgh / TTL ≥ 0.5, it can meet both the user's high pixel requirements for the optical camera lens group 10 and the miniaturization requirements.

[0076] In some embodiments, the optical camera lens group 10 satisfies the following conditional expression: Imgh / TTL ≥ 0.7; that is to say, Imgh / TTL can be any value greater than or equal to 0.7. For example, this value can be 0.700, 0.709, 0.713, 0.739, 0.756, 0.769, 0.817, and so on.

[0077] Compared with the optical camera lens group 10 that satisfies the conditional expression Imgh / TTL ≥ 0.5, the optical camera lens group 10 that satisfies the conditional expression Imgh / TTL ≥ 0.7 can further meet both the user's high pixel requirements for the optical camera lens group 10 and the miniaturization requirements.

[0078] In some embodiments, the optical camera lens group 10 satisfies the following conditional expression: -5 < (R8 + R9) / (R8 - R9) < 260; where R8 is the curvature radius of the object side surface S7 of the fourth lens L4, and R9 is the curvature radius of the image side surface S8 of the fourth lens L4. That is to say, (R8 + R9) / (R8 - R9) can be any value within the interval (-5, 260). For example, this value can be -4.186, -0.624, 1.057, 1.986, 2.099, 4.369, 4.540, 7.114, 13.194, 17.861, 247.449, and so on.

[0079] When the optical camera lens group 10 satisfies the conditional formula -5 < (R8 + R9) / (R8 - R9) < 260, by reasonably restricting the relationship between the object side S7 and the image side S8 of the fourth lens L4, the optical camera lens group 10 can effectively distribute the optical deflection angles borne by the lenses and improve the astigmatism of the off-axis field of view at the same time.

[0080] In some embodiments, the optical camera lens group 10 satisfies the following conditional formula: -7 < R12 / R13 < 3.5; where R12 is the radius of curvature of the object side S11 of the sixth lens L6, and R13 is the radius of curvature of the image side S12 of the sixth lens L6. That is to say, R12 / R13 can be any value within the interval (-7, 3.5). For example, this value can be -6.627, -6.090, -6.076, -6.026, -4.596, 1.187, 1.483, 1.513, 1.922, 3.066, 3.347, and so on.

[0081] When the optical camera lens group 10 satisfies the conditional formula -7 < R12 / R13 < 3.5, by adjusting the radius of curvature of the sixth lens L6, the spherical aberration and astigmatism of the optical camera lens group 10 can be effectively corrected, thereby improving the imaging quality of the optical camera lens group 10.

[0082] In some embodiments, the optical camera lens group 10 satisfies the following conditional formula: 0.5 < |f2 / R4| < 2; where f2 is the focal length of the second lens L2, and R4 is the radius of curvature of the object side S3 of the second lens L2. That is to say, |f2 / R4| can be any value within the interval (0.5, 2). For example, |f2 / R4| can be 0.730, 0.778, 0.781, 0.796, 0.827, 0.871, 0.940, 0.980, 1.249, 1.297, 1.713, and so on.

[0083] When the optical camera lens group 10 satisfies the conditional formula 0.5 < |f2 / R4| < 2, the aberration generated by the optical camera lens group 10 can be balanced, and at the same time, the high-order aberration generated by the second lens L2 can be further corrected to improve the imaging quality.

[0084] In some embodiments, the optical camera lens group 10 satisfies the following conditional formula: -5 < R6 / f3 < 2.0; where R6 is the radius of curvature of the object side S5 of the third lens L3, and f3 is the focal length of the third lens L3. That is to say, R6 / f3 can be any value within the interval (-5, 2.0). For example, this value can be -3.726, -0.465, -0.013, 0.074, 0.144, 0.211, 0.304, 0.391, 0.509, 1.035, 1.822, and so on.

[0085] When the optical camera lens group 10 satisfies the conditional formula -5 < R6 / f3 < 2.0, it can balance aberrations such as astigmatism and distortion generated by the optical camera lens group 10, and at the same time can further correct the high-order aberrations generated by the third lens L3.

[0086] In some embodiments, the optical camera lens group 10 satisfies the following conditional formula: (CT1 + CT2 + CT3) / TTL < 0.3; where CT1 is the central thickness of the first lens L1 on the optical axis, CT2 is the central thickness of the second lens L2 on the optical axis, CT3 is the central thickness of the third lens L3 on the optical axis, and TTL is the distance from the object side surface S1 of the first lens L1 to the imaging surface S15 on the optical axis. That is to say, (CT1 + CT2 + CT3) / TTL can be any value less than 0.3. For example, this value can be 0.241, 0.244, 0.252, 0.254, 0.256, 0.258, 0.259, 0.263, 0.265, 0.284, and so on.

[0087] When the optical camera lens group 10 satisfies the conditional formula (CT1 + CT2 + CT3) / TTL < 0.3, the first lens L1, the second lens L2, and the third lens L3 have a reasonable thickness configuration, which is beneficial to reducing the sensitivity of the optical camera lens group 10 and shortening the overall optical length of the optical camera lens group 10.

[0088] In some embodiments, the optical camera lens group 10 satisfies the following conditional formula: 12 < f45 / CT34 < 85; where f45 is the combined focal length of the fourth lens L4 and the fifth lens L5, and CT34 is the air gap between the third lens L3 and the fourth lens L4 on the optical axis. That is to say, f45 / CT34 can be any value within the interval (12, 85). For example, this value can be 12.775, 15.125, 16.299, 17.397, 17.762, 20.707, 22.487, 25.884, 34.808, 39.195, 82.176, and so on.

[0089] When the optical camera lens group 10 satisfies the conditional formula 12 < f45 / CT34 < 85, it can reasonably distribute the refractive power of the optical camera lens group 10, improve the imaging quality, and reduce the size of the optical camera lens group 10.

[0090] In some embodiments, the optical camera lens assembly 10 further includes a filter L7. Filter L7 is disposed between the sixth lens element L6 and the imaging surface S15. In an embodiment of the present invention, filter L7 is an infrared filter L7. When the optical camera lens assembly 10 is used for imaging, light emitted from or reflected by the subject enters the optical camera lens assembly 10 from the object side and sequentially passes through the first lens element L1, the second lens element L2, the third lens element L3, the fourth lens element L4, the fifth lens element L5, the sixth lens element L6, and the object-side surface S13 and image-side surface S14 of the infrared filter L7, ultimately converging onto the imaging surface S15.

[0091] In some embodiments, the first through sixth lenses L1 through L6 are plastic lenses. In the first through eleventh embodiments of the present invention, the first through sixth lenses L1 through L6 are all plastic lenses. Thus, by rationally configuring lens materials, the optical camera lens assembly 10 achieves ultra-thinness and low cost while correcting for aberrations and addressing temperature drift.

[0092] In certain embodiments, at least one surface of the first through sixth lenses L1 through L6 in the optical camera lens system 10 is aspherical. For example, in the first through eleventh embodiments, both the object-side and image-side surfaces of the first through sixth lenses L1 through L6 are aspherical. The shape of the aspherical surface is determined by the following formula: Where Z is the longitudinal distance from any point on the aspheric surface to the vertex of the surface, r is the distance from any point on the aspheric surface to the optical axis, c is the vertex curvature (the inverse of the curvature radius), k is the cone constant, and Ai is the correction coefficient of the i-th order aspheric surface.

[0093] In this way, the optical camera lens assembly 10 can effectively reduce the total length of the optical camera lens assembly 10 by adjusting the curvature radius and aspheric coefficient of each lens surface, and can effectively correct aberrations to improve imaging quality.
