Description

一种成像镜头、摄像模组及电子设备
本申请要求于2023年10月18日提交到国家知识产权局、申请号为202311351973.5、发明名称为“一种成像镜头、摄像模组及电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及光学成像技术领域，尤其涉及一种成像镜头、摄像模组及电子设备。
背景技术
随着摄像设备技术的发展，越来越多的移动终端设备具备摄像功能。用户对于移动终端的摄像功能的要求也逐渐多元化，期望移动终端能够实现在远景、微距及暗光场景中均具有良好的拍摄效果。
对于移动终端设备，例如手机，为了更加便于用户携带和使用终端设备，以及提高终端设备的美观度，会逐渐缩小终端设备的厚度，并导致终端设备在厚度方向上的内部空间愈发狭小。通常，在终端设备的厚度方向上配置摄像模组，终端设备在厚度方向上狭小的内部空间将严重限制摄像模组的整体尺寸。
而为了实现在远景、微距及暗光场景中均具有良好的摄影效果，需要通过长焦镜头等摄像模组进行成像。传统的长焦镜头通过马达移动镜头整体来实现对焦，不利于摄像模组的小型化，且通过马达移动镜头实现对焦，在微距时长焦镜头的成像质量很差，长焦微距拍摄效果较差。同时受限于移动终端中模组体积的要求，长焦镜头的光圈较小、靶面较小，暗光拍摄效果差。
发明内容
本申请实施例提供了一种成像镜头、摄像模组及电子设备，以解决配置在移动终端中的长焦镜头微距及暗光拍摄效果差的问题。
第一方面，本申请实施例提供一种成像镜头，沿光轴从物侧至像侧依次包括第一透镜组和第二透镜组；第一透镜组沿光轴从物侧至像侧依次包括具有正屈折力的第一透镜、具有负屈折力的第二透镜、具有正屈折力的第三透镜；第二透镜组沿光轴从物侧至像侧依次包括具有正屈折力的第四透镜、具有负屈折力的第五透镜、具有负屈折力的第六透镜。
其中，第一透镜组的位置相对于摄像模组的成像面固定；第二透镜组位于第一透镜组与成像面之间，第二透镜组被配置为可沿光轴在第一透镜组与成像面之间移动；第一透镜组的有效焦距FG1、第二透镜组的有效焦距FG2、成像镜头在对焦无穷远时的有效焦距Finf满足：1<(FG1-FG2)/Finf<2。
根据上述成像镜头，通过设置第一透镜组和第二透镜组，并对两个透镜组中的透镜的屈折力进行限定，使成像镜头能够接收更大角度的入射光线，并收敛成像镜头的像差及色差，实现长焦大光圈的特征并提升成像镜头的成像性能。同时，对第一透镜组和第二透镜组的有效焦距与成像镜头对焦无穷远时的有效焦距进行设计，可提高成像镜头在无穷远物距到近焦物距下的成像质量。
在一种实现方式中，第一透镜的物侧面于近光轴处为凸面；第二透镜的物侧面于近光轴处为凹面，第二透镜的像侧面于近光轴处为凹面；第三透镜的物侧面于近光轴处为凸面，第三透镜的像侧面于近光轴处为凸面；第四透镜的物侧面于近光轴处为凹面，第四透镜的像侧面于近光轴处为凸面；第五透镜的像侧面于近光轴处为凹面；第六透镜的物侧面于近光轴处为凹面，第六透镜的像侧面于近光轴处为凹面。这样，通过合理设计第一透镜组和第二透镜组中不同透镜的面型，使成像镜头能够接收更大角度的入射光线，并使进入成像镜头的光线平稳过渡，令光线的走势更加平顺，从而实现大光圈、大靶面的特征，以提高成像镜头的成像质量。
在一种实现方式中，第一透镜的有效焦距f1，与成像镜头在对焦无穷远时的有效焦距Finf满足：0.3<f1/Finf<1。这样，通过对第一透镜的有效焦距进行约束，能够平衡成像镜头的球差，提高成像镜头的成像质量。同时第一透镜还可使成像镜头能够接收更大角度的入射光线，扩大成像镜头的视场角范围，进而实现长焦大光圈、大靶面的特征。
在一种实现方式中，第一透镜的有效焦距f1，与第二透镜的有效焦距f2满足：-2.8<f1/f2<-1.5。这样，通过对第一透镜和第二透镜的有效焦距的约束，使第二透镜能够对经由第一透镜入射的光线进行过渡，减少大角度入射光线的弯折角度，平衡成像镜头的慧差，同时保证整个系统在高低温状态下的成像性能。
在一种实现方式中，成像镜头在对焦无穷远时的有效焦距Finf，与成像镜头在对焦微距时的有效焦距Fmac满足：Finf/Fmac<1.5。这样，通过约束成像镜头在远焦状态和近焦状态的有效焦距的比例，从而对第二透镜组在光轴上的移动范围进行限定，在具有较高成像性能的基础上，实现成像镜头的小型化。
在一种实现方式中，第三透镜的有效焦距f3，与第一透镜组的有效焦距FG1满足：0.2<f3/FG1<1.0。这样，通过约束第三透镜的有效焦距，使第三透镜能够将经由第一透镜和第二透镜入射的光线进行收缩，减少边缘光线的偏差，从而平衡成像镜头的球差及慧差，提高长焦大光圈的成像镜头的成像质量。
在一种实现方式中，第六透镜的有效焦距f6，与第二透镜组的有效焦距FG2满足：0.5<f6/FG2<3。这样，通过约束第六透镜的有效焦距与第二透镜组的有效焦距的比例，可对成像镜头的场曲进行平衡，提高成像镜头近焦状态下的成像性能。
在一种实现方式中，第四透镜在光轴上的中心厚度CT4、第四透镜的物侧面的曲率半径R41，以及，第四透镜的像侧面的曲率半径R42满足：0.5<CT4*(R42/R41)<3。这样，通过对第四透镜的中心厚度及物侧面、像侧面的曲率半径进行约束，可以控制第四透镜的形状，对光线进行有效控制，从而对场曲和像散进行平衡，并有利于实现大靶面的特征，提高成像镜头的成像质量。
在一种实现方式中，第三透镜的像侧面的曲率半径R32，与第四透镜的物侧面的曲率半径R41满足：0.5<R41/R32<5。这样，可对第一透镜组和第二透镜组中相邻的透镜进行约束，使光线平缓地由第一透镜组进入第二透镜组中，减少第一透镜组和第二透镜组间的组装公差敏感性，降低组装难度，提高成像镜头的成像质量及组装工艺性。
在一种实现方式中，第四透镜和第五透镜的组合焦距f45，与第五透镜和第六透镜在光轴上的空间间隔T56满足：-100<f45/T56<-5。这样，通过分配第二透镜组中第四透镜和第五透镜的组合焦距以及第五透镜和第六透镜在光轴上的空间间隔，使第二透镜组能够平衡场曲、像散，同时还可为结构件预留组装位置，便于成像镜头设置在终端设备中。
在一种实现方式中，微距对焦时第六透镜像侧面和成像面在光轴方向的距离BFLmin，与第一透镜物侧面和成像面在光轴方向的距离TTL满足：BFLmin/TTL>0.05。这样，可通过对第六透镜在近焦状态时像侧面和成像面的距离的约束，对成像镜头的对焦行程进行优化，同时还可对成像镜头进行结构优化，便于音圈马达结构的排布，进而实现成像镜头的小型化。
第二方面，本申请实施例提供了一种摄像模组，由物侧至像侧依次包括：光阑、如前述中任一种成像镜头，以及，成像面。根据上述摄像模组，具有该成像镜头的摄像模组在结构小型化的基础上，还具有长焦大光圈、大靶面的特征，从而提高摄像模组的成像性能。
第三方面，本申请实施例提供了一种电子设备，包括前面板、中框、后盖、以及如前述的摄像模组，其中：前面板上设有显示屏，中框设置在前面板与后盖之间，后盖上设有摄像孔；摄像模组通过摄像孔设置在电子设备中，摄像模组中的成像镜头的光轴方向与电子设备的厚度方向平行。由此，可使电子设备中设有该摄像模组，进而通过该摄像模组，实现小型化。

本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请，下面将结合附图对本申请的实施例进行详细描述。
随着摄像设备技术的发展，越来越多的移动终端设备具备摄像功能，如智能手机、平板电脑、摄像机、数码相机等设备，均设有摄影模块来实现摄影功能。本申请实施例以智能手机为例进行说明。
图1为具有电子摄像功能的电子设备在厚度方向上的结构示意图。如图1所示，该电子设备100包括前面板110、中框120、后盖130、电子元件140和摄像模组150，其中前面板110、中框120和后盖130围合形成一个腔室，电子元件140和摄像模组150设置在该腔室内。
在本申请实施例中，摄像模组150可为电子设备100的前置摄像头和/或后置摄像头，对于摄像模组150的具体设置位置本申请中不做限制。
图2为摄像模组150的内部结构示意图，如图2所示，摄像模组150包括光阑151、成像镜头152和图像传感器(Sensor)153。摄像模组150还可以包括其它与成像相关的组件，例如：保护膜、音圈马达(Voice Coil Motor，VCM)、滤光片、底座、导电布、软硬结合板和连接器等，此处不一一列举。
为了满足用户对电子设备100的摄像功能的要求，需要成像镜头152在远距、微距以及 暗光条件下均具有良好的成像质量，示例性的，可通过组合多个透镜的方式构成成像镜头152并进行成像。如图2所示，成像镜头152包括n个沿成像镜头152的光轴方向依次排列的透镜1521，其中n为大于1的正整数，成像镜头152的光轴方向同电子设备100的厚度方向。
图像传感器153包括感光元件，如电荷耦合元件(Charge coupled Device，CCD)、互补金属氧化物半导体(Complementary Metal Oxide Semiconductor，CMOS)。图像传感器153用于感应成像镜头152聚焦的光线，并在成像面上形成对应于景物的电子图像，其中，成像面是图像传感器153朝向透镜1521的一侧表面。
随着成像镜头152中透镜1521的数量的增加，成像镜头152汇聚光线的能力越高，可以有效提高成像镜头152的解析力和对比度，且能够提高成像镜头152的防眩光效果及成像质量。但是，相应的，成像镜头152的厚度也会越大。
为了便于用户的手持，以及提高电子设备100的美观度，会逐渐降低电子设备100在厚度方向上的尺寸。为了适应电子设备100在厚度方向上缩小的尺寸，摄像模组150在电子设备100的厚度方向上的尺寸也需要缩小，相应的，成像镜头152在电子设备100的厚度方向上的尺寸也需要缩小。
在此基础上，随用户对摄影效果要求的提升，为了实现在远景、微距及暗光场景中均具有良好的摄影效果，需要通过应用长焦镜头的摄像模组150进行成像。但传统的长焦镜头通过马达移动镜头整体来实现对焦，不利于摄像模组150的小型化，且通过马达移动镜头实现对焦，在微距时长焦镜头的成像质量很差，长焦微距拍摄效果较差。同时受限于移动终端中模组体积的要求，小型化后的长焦镜头的光圈较小、靶面较小，暗光拍摄效果差。
为了解决上述问题，需要在保证成像镜头152包括足够数量的透镜1521，以及有效控制成像镜头152在电子设备100的厚度方向上的尺寸的基础上，还需要对成像镜头152中的透镜1521做出合理的设计，从而提高其在微距或暗光环境中的成像质量。
图3为本申请实施例提供的一种摄像模组200的结构示意图，图4为本申请实施例提供的另一种摄像模组200的结构示意图。
在本申请实施例中，如图3所示，摄像模组200沿光轴201从物侧至像侧依次包括光阑ST0、成像镜头210和成像面L8。在一些实施例中，如图4所示，摄像模组200还可以包括滤光片L7，滤光片L7设置于成像镜头210和成像面L8之间。
如图3和图4所示，成像镜头210沿光轴201从物侧至像侧依次包括第一透镜组211和第二透镜组212，其中第一透镜组211沿光轴201从物侧至像侧依次包括第一透镜L1、第二透镜L2和第三透镜L3；第二透镜组212沿光轴201从物侧至像侧依次包括第四透镜L4、第五透镜L5和第六透镜L6。

应当理解的是，在本申请实施例中，物侧是指靠近所拍摄景物的一侧，像侧是指靠近图像传感器的一侧。因此，成像镜头210中的每个透镜均具有物侧面和像侧面，其中，物侧面是指透镜中朝向物侧的镜面，像侧面是指透镜中朝向像侧的镜面。如图3和图4所示，第一透镜L1包括物侧面E11和像侧面E12，第二透镜L2包括物侧面E21和像侧面E22，第三透镜L3包括物侧面E31和像侧面E32，第四透镜L4包括物侧面E41和像侧面E42，第五透镜L5包括物侧面E51和像侧面E52，第六透镜L6包括物侧面E61和像侧面E62。
如图3和图4所示，光阑ST0设置在物侧与成像镜头210之间，且在部分实施例中，光阑ST0为环形片状结构，能够阻挡由成像镜头210边缘入射的光线。应当理解的是，光阑ST0 的圈口越大，通光量越高，光阑ST0的圈口越小，通光量越低。
在部分实施例中，滤光片L7也具有物侧面IR1和像侧面IR2，滤光片L7用于校正色彩偏差和/或保护位于成像面L8上的感光元件。滤光片L7可以包括蓝玻璃和/或IR-CUT双滤镜等，对于滤光片L7的具体种类本申请实施例中不做限制。
在实际应用中，入射光线在进入成像镜头210前，会有部分边缘光线被光阑ST0拦截，无法进入成像镜头210中。而未被光阑ST0拦截的入射光线则从第一透镜L1的物侧面E11射入，而后入射光线依次经过后续各个透镜，从第六透镜L6的像侧面E62射出。出射光线从滤光片L7的物侧面IR1射入并经由像侧面IR2射出，经过滤光片L7过滤处理的出射光线入射至成像面L8上，由成像面L8感应该光线，并生成对应的电子图像。

需要说明的是，透镜的物侧面的凹凸以像侧为参考，物侧面背离像侧弯曲为凸，物侧面朝向像侧弯曲为凹。透镜的像侧面的凹凸以物侧为参考，像侧面朝向物侧弯曲为凹，像侧面背离物侧弯曲为凸。
配合不同透镜的面型设计，不同的透镜具有不同的光学性能。其中，具有正屈折力的第一透镜L1，能够快速汇聚入射光线，收敛成像镜头210的通光口径，同时还可接收更大角度的入射光线，提高成像的视场角范围。
具有负屈折力的第二透镜L2，则可使大角度的入射光线过渡得更加平缓，减少场曲和球差。
具有正屈折力的第三透镜L3，可以收缩入射光线，减少边缘光线的偏差，从而平衡成像镜头的球差及慧差。
具有正屈折力的第四透镜L4，可以对成像镜头210产生的场曲和像散进行平衡。
具有负屈折力的第五透镜L5，可以减少成像镜头210产生的像差和色差。

1<(FG1-FG2)/Finf<2           (1)
通过对第一透镜组211和第二透镜组212的有效焦距与成像镜头210对焦无穷远时的有效焦距进行设计，可提高成像镜头在无穷远物距到近焦物距下的成像质量，避免对焦不同距离物体时产生的成像质量不一的情况。
在一些实施例中，第一透镜L1的有效焦距f1，与成像镜头210在对焦无穷远时的有效焦距Finf满足关系式(2)：
0.3<f1/Finf<1             (2)
在本实施例中，通过对第一透镜L1的有效焦距f1进行约束，能够平衡成像镜头210的球差，提高成像镜头210的成像质量。同时结合第一透镜L1的面型设计，第一透镜L1还可使成像镜头210能够接收更大角度的入射光线，扩大成像镜头210的视场角范围，进而实现长焦大光圈、大靶面的特征。
在一些实施例中，第一透镜L1的有效焦距f1，与第二透镜L2的有效焦距f2满足关系式(3)：
-2.8<f1/f2<-1.5          (3)

Finf/Fmac<1.5             (4)
这样，通过约束成像镜头210在远焦状态和近焦状态的有效焦距的比例，从而对第二透镜组212在光轴201上的移动范围进行限定，在具有较高成像性能的基础上，实现成像镜头的小型化，使得成像镜头210可应用在厚度更小的电子设备当中。
在一些实施例中，第三透镜L3的有效焦距f3，与第一透镜组211的有效焦距FG1满足关系式(5)：
0.2<f3/FG1<1.0            (5)
这样，通过约束第三透镜L3的有效焦距，使第三透镜L3能够将经由第一透镜L1和第二透镜L2入射的光线进行收缩，减少边缘光线的偏差，从而平衡成像镜头210的球差及慧差，提高长焦大光圈的成像镜头210的成像质量。
在一些实施例中，第六透镜L6的有效焦距f6，与第二透镜组212的有效焦距FG2满足关系式(6)：
0.5<f6/FG2<3           (6)
这样，通过约束第六透镜L6的有效焦距与第二透镜组212的有效焦距的比例，可对成像镜头210的场曲进行平衡，提高成像镜头210近焦状态下的成像性能。
在一些实施例中，第四透镜L4在光轴201上的中心厚度CT4、第四透镜L4的物侧面E41的曲率半径R41，以及，第四透镜L4的像侧面E42的曲率半径R42满足关系式(7)：
0.5<CT4*(R42/R41)<3           (7)
这样，通过对第四透镜L4的中心厚度及物侧面E41、像侧面E42的曲率半径进行约束，可以控制第四透镜L4的形状，对光线进行有效控制，从而对场曲和像散进行平衡，并有利于实现大靶面的特征，提高成像镜头210的成像质量。
在一些实施例中，第三透镜L3的像侧面E32的曲率半径R32，与第四透镜L4的物侧面E41的曲率半径R41满足关系式(8)：
0.5<R41/R32<5             (8)
这样，可对第一透镜组211和第二透镜组212中相邻的透镜进行约束，使光线平缓地由第一透镜组211进入第二透镜组212中，减少第一透镜组211和第二透镜组212间的组装公差敏感性，降低组装难度，提高成像镜头210的成像质量及组装工艺性。
在一些实施例中，第四透镜L4和第五透镜L5的组合焦距f45，与第五透镜L5和第六透镜L6在光轴201上的空间间隔T56满足关系式(9)：
-100<f45/T56<-5              (9)
这样，通过分配第二透镜组212中第四透镜L4和第五透镜L5的组合焦距以及第五透镜L5和第六透镜L6在光轴201上的空间间隔，使第二透镜组212能够平衡场曲、像散，同时还可为结构件预留组装位置，便于成像镜头210设置在终端设备中。
在一些实施例中，微距对焦时第六透镜L6的像侧面E62和成像面L8在光轴201方向的距离BFLmin，与第一透镜L1的物侧面E11和成像面L8在光轴201方向的距离TTL满足关系式(10)：
BFLmin/TTL>0.05           (10)
这样，可通过对第六透镜L6在近焦状态时像侧面E62和成像面L8的距离的约束，对成像镜头210的对焦行程进行优化，同时还可对成像镜头210进行结构优化，便于音圈马达结构的排布，进而实现成像镜头210的小型化。
在一些实施例中，各透镜包括至少一个非球面透镜，即第一透镜L1的物侧面E11至第六透镜L6的像侧面E62中至少一个镜面为非球面镜面。非球面透镜具有从透镜中心到透镜边缘，曲率连续变化的特点。与从透镜中心到透镜边缘具有恒定曲率的球面透镜不同，非球面透镜具有更佳的曲率半径特性，具有改善像差的优点。采用非球面透镜后，能够尽可能地消除在成像的时候出现的像差，从而提高成像质量。
在一些实施例中，第一透镜L1、第二透镜L2、第三透镜L3、第四透镜L4、第五透镜L5和第六透镜L6中每个透镜的物侧面和像侧面中至少一个为非球面镜面。
在一些实施例中，第一透镜L1、第二透镜L2、第三透镜L3、第四透镜L4、第五透镜L5和第六透镜L6中每个透镜的物侧面和像侧面均为非球面镜面。
在一些实施例中，各透镜包括至少一个玻璃透镜。示例性的，成像镜头210中的第一透镜L1可为玻璃透镜，其余可为塑料透镜，相较于塑料透镜来说，玻璃透镜在有更高的折射率的基础上具有较低的色散系数，使第一透镜L1在具有良好的光学性能的条件下，还能够降低其温度敏感性，使成像镜头210能够应用在更多的环境中。前述透镜材质仅为本申请中一种示例性说明，本申请中对于各透镜的具体材质构成不做限制。
由此，本申请实施例提供的成像镜头210既可以在暗环境下提高镜头的进光量，增强画质，又可以避免在亮环境下出现过度曝光等不利影响。通过合理分配成像镜头中各透镜的屈折力、面型、材质、尺寸等，可以有效地汇聚入射光线，降低像差和像散，以在使成像镜头210可以适应终端设备在厚度方向上的尺寸的基础上，有效提高成像镜头210在复杂光环境下的成像质量，并且可以有效提高各透镜的加工及组装的便利性。相应的，本申请实施例提供的摄像模组200也可以在适应终端设备在厚度方向上的尺寸的基础上，具有长焦大光圈、大靶面和高成像质量等特性。
