【具体实施方式】
以下，通过发明的实施方式来对本发明进行说明，但是以下实施方式并非限制权利要求书所涉及的发明。此外，实施方式中说明的特征的所有组合未必是发明的解决方案所必须的。对本领域普通技术人员来说，显然可以对以下实施方式加以各种变更或改良。从权利要求书的描述显而易见的是，加以了这样的变更或改良的方式都可包含在本发明的技术范围之内。
权利要求书、说明书、附图以及摘要中包含作为著作权所保护对象的事项。任何人只要如专利局的文档或者记录所表示的那样进行这些文件的复制，著作权人就无法异议。但是，在除此以外的情况下，保留一切的著作权。
图1是示出了本实施方式所涉及的摄像系统10的外观立体图的一个示例的图。图2是示出了从侧面侧观察摄像系统10的外观图的一个示例的图。
摄像系统10包括主体100、保持机构200、万向节300和摄像装置400。摄像装置400在内部包括图像传感器430。摄像装置400可拆装地保持镜头单元。保持机构200以能够相对于主体100在Z轴(偏航轴)方向可移动的方式保持万向节300。保 持机构200包括保持部202和旋转部204。保持部202经由旋转部204固定于主体100。保持部202保持万向节300。旋转部204可以以能够旋转的方式与保持部202的一端连接，万向节300可以以能够以偏航轴为中心旋转的方式与另一端连接。旋转部204包括包括转子的致动器，通过致动器驱动而能够旋转。
万向节300是可旋转地支撑摄像装置400的支撑机构的一个示例。摄像装置400可以包括容纳图像传感器430的壳体，且万向节300可旋转地支撑壳体。万向节300使用致动器以X轴(俯仰轴)为中心可旋转地支撑摄像装置400。万向节300使用致动器进一步分别以Y轴(滚转轴)和Z轴(偏航轴)为中心可旋转地支撑摄像装置400。万向节300可以通过以偏航轴、俯仰轴以及滚转轴中的至少1个为中心旋转摄像装置400，来改变图像传感器430的姿势。
万向节300包括旋转部301、旋转部303、旋转部305、支撑部302以及支撑部304。旋转部301、旋转部303以及旋转部305包括包括转子的致动器。旋转部301设置在支撑部302的一端。旋转部303设置在支撑部302的另一端。支撑部302的另一端经由旋转部303与支撑部304的一端连接。旋转部305设置在支撑部304的另一端。支撑部304的另一端经由旋转部305与保持部202的另一端连接。支撑部302以摄像装置400能够通过旋转部301以俯仰轴为中心旋转的方式支撑摄像装置400。即，支撑部302是以摄像装置400能够在俯仰方向上旋转的方式支撑摄像装置400的第一支撑部的一个示例。支撑部304以摄像装置400能够通过旋转部303以滚转轴为中心旋转的方式支撑支撑部302。即，支撑部304是以摄像装置400能够在纵摇方向上旋转的方式支撑支撑部302的第二支撑部的一个示例。支撑部304以摄像装置400能够通过旋转部305在横摇方向上旋转的方式由保持部202支撑。
摄像装置400可拆装地保持包括至少1个镜头的镜头单元。镜头单元可以是可更换镜头。
在如上所述构成的摄像系统10中，在摄像装置400上能够可拆装地安装各种镜头单元。但是，在镜头单元中，也存在不符合摄像装置400的标准的镜头单元。为了使摄像装置400能够保持这样的标准之外的镜头单元，摄像系统10还可以包括连接摄像装置400和镜头单元的卡口适配器。
图3是卡口适配器500安装在摄像装置400上的摄像系统10的外观立体图的一个示例。图4是卡口适配器500安装在摄像装置400上的摄像系统10的从侧面侧观察到的外观图的一个示例。卡口适配器500包括符合与摄像装置400连接的镜头单元的标准的卡口结构。通过这样的卡口适配器500，能够在摄像装置400上安装各种镜头单元。在卡口适配器500上可以可拆装地连接有不符合摄像装置400的卡口结构的标准的镜头单元。在卡口适配器500上也可以可拆装地连接有符合摄像装置400的卡口结构的标准的镜头单元。
在镜头单元中，也有由于重量大或者长度长等原因万向节300难以稳定地支撑的镜头单元。即，在镜头单元中，也有难以维持摄像装置400相对于主体100的位置的镜头单元。因此，摄像系统10还可以包括支撑摄像装置400以维持摄像装置400相对于主体100的位置的支撑体。
图5是支撑体150安装在主体100上的摄像系统10的外观立体图的一个示例。图6是从侧面侧观察到的支撑体150安装在主体100上的摄像系统10的外观图的一个示例。
支撑体150支撑摄像装置400以维持摄像装置400相对于主体100的位置。支撑体150可以固定在主体100和摄像装置400上。支撑体150可以经由螺栓152固定于主体100。支撑体150包括比螺栓152的外径大的贯通开口。螺栓152经由这个贯通开口螺纹固定于主体100。支撑体150在外表面包括表示图像传感器430的摄像面的位置的标记151。支撑体150可以在支柱的侧面包括标记151。另外，在摄像装置400 被支撑体150支撑的情况下，万向节300不控制摄像装置400的姿势。即，万向节300不工作。
如图3及图4所示，主体100包括用于固定支撑体150的固定面140。固定面140位于摄像装置400和卡口适配器500的下方。主体100可以在固定面140包括用于检测支撑体150是否安装于主体100的检测传感器132。检测传感器132可以是机械开关，其对应于支撑体150安装于固定面140的情况而接通。检测传感器132可以是电元件，其对应于支撑体150安装于固定面140的情况而电导通。
通过支撑体150支撑摄像装置400，万向节300能够稳定地支撑各种镜头单元。另外，支撑体150也可以不固定于卡口适配器500，而固定于摄像装置400。或者，支撑体150也可以分别固定于卡口适配器500和摄像装置400。
保持机构200以摄像装置400能够向接近固定面140的方向及远离其的方向移动的方式保持万向节300。保持机构200包括旋转部204，其使保持万向节300的保持部202以沿着固定面140的轴(俯仰轴)为中心相对于主体100旋转。因此，保持机构200能够调整摄像装置400距固定面140的高度。由此，能够防止由于摄像装置400相对于主体100在Z方向上发生位置偏移，导致支撑体150无法固定于卡口适配器500或摄像装置400。
图7是从摄像装置400拆下卡口适配器500的状态的从正面侧观察到的卡口适配器500，摄像装置400和万向节300的外观立体图的一个示例。图8是从摄像装置400拆下卡口适配器500的状态的从背面侧观察到的卡口适配器500，摄像装置400和万向节300的外观立体图的一个示例。
摄像装置400包括使图像传感器430露出的开口401。开口401可以是圆形。摄像装置400在开口401的周围包括镜头卡口402。镜头卡口402可以是所谓的卡口式镜头卡口。镜头卡口402包括卡口侧卡合部406。卡口侧卡合部406朝向开口401的 内侧突出。卡口侧卡合部406可以是朝向开口401的内侧突出的凸缘。镜头卡口402沿着开口401的边缘包括触点部404。
卡口适配器500包括底座部502。底座部502可以是矩形的板状部件。底座部502在与开口401相对的位置包括开口501。卡口适配器500在底座部502的第一面503包括可拆装地连接镜头单元的连接部504。连接部504是第一连接部的一个示例。连接部504可以包括所谓的卡口式卡口结构。连接部504在开口501的周围包括与镜头单元的触点部电连接的触点部506。连接部504包括朝向开口501的内侧突出的适配器侧卡合部505。适配器侧卡合部505是第二适配器侧卡合部的一个示例。适配器侧卡合部505可以是朝向开口501的内侧突出的凸缘。连接部504可以包括多个适配器侧卡合部505。连接部504可以沿着开口501的边缘部包括3个适配器侧卡合部505。通过镜头单元相对于卡口适配器500旋转，适配器侧卡合部505与镜头单元包括的镜头侧卡合部卡合，镜头单元与卡口适配器500连接。在此，适配器侧卡合部505与镜头侧卡合部卡合的状态的概念包括：镜头侧卡合部的至少一部分位于适配器侧卡合部505的至少一部分的背侧并重叠，且镜头单元相对于卡口适配器500在光轴方向上的移动受到限制的状态。这个状态的状态包括：镜头侧卡合部的至少一部分在光轴方向上与适配器侧卡合部505的至少一部分重叠，但镜头侧卡合部的至少一部分不与适配器侧卡合部505的至少一部分接触的状态。
底座部502在与第一面503相反的第二面511上包括可拆装地连接于摄像装置400的连接部510。连接部510是第二连接部的一个示例。连接部510包括与摄像装置400的卡口侧卡合部406卡合的适配器侧卡合部512。适配器侧卡合部512是第一适配器侧卡合部的一个示例。连接部510可以包括多个适配器侧卡合部512。适配器侧卡合部512可以朝向开口501的外侧突出。适配器侧卡合部512可以是朝向开口501的外侧突出的凸缘。适配器侧卡合部512与摄像装置400的卡口侧卡合部406卡合，从而卡口适配器500与摄像装置400连接。在此，适配器侧卡合部512与卡口侧 卡合部406卡合的状态的概念包括：适配器侧卡合部512的至少一部分位于摄像装置400的卡口侧卡合部406的至少一部分的背侧并重叠，且卡口适配器500相对于摄像装置400在光轴方向上的移动受到限制的状态。这个状态的概念包括：适配器侧卡合部512的至少一部分在光轴方向上与摄像装置400的卡口侧卡合部406的至少一部分重叠，但适配器侧卡合部512的至少一部分不与摄像装置400的卡口侧卡合部406的至少一部分接触的状态。
底座部502在第二面511还包括与摄像装置400的触点部404电连接的触点部514。底座部502可以沿着开口501包括多个触点部514。
摄像装置400可旋转地与设置于万向节300的支撑部302的一端的旋转部301连接。旋转部301包括致动器，并从镜头卡口402的卡口面突出。底座部502在侧部包括与旋转部301对应的凹部550。在卡口适配器500安装于摄像装置400的情况下，旋转部301嵌入凹部550。
在此，从镜头卡口402的卡口面突出的旋转部301成为屏障，无法通过使卡口适配器500相对于摄像装置400旋转来使适配器侧卡合部512与卡口侧卡合部406卡合，并安装于摄像装置400。因此，连接部510还包括旋转体513。旋转体513是圆环状的部件。旋转体513以能够相对于底座部502旋转的方式设置于底座部502的开口501。
卡口适配器500还包括保持部516，其保持触点部514，并且相对于底座部502可旋转地保持旋转体513。保持部516可以固定于底座部502的第二面511。保持部516包括使触点部514露出的通孔。保持部516包括供旋转体513的一部分贯通的通孔。保持部516相对于底座部502可旋转地覆盖旋转体513的突出部分以外的其他部分。
适配器侧卡合部512从旋转体513的从保持部516突出的部分的外周面向外侧突出地设置。卡口适配器500还包括操作部520，其用于使旋转体513与适配器侧卡合 部512一起相对于底座部502旋转。操作部520在相对于摄像装置400拆装连接部510时被操作。
旋转体513与操作部520和适配器侧卡合部512连接，与操作部520相对于底座部502相对地移动的情况进行连动，来与适配器侧卡合部512一起相对于底座部502相对地旋转。旋转体513可以与适配器侧卡合部512一体地构成。适配器侧卡合部512与操作部520相对于底座部502相对地移动的情况进行连动，并相对于底座部502相对地移动，从而与摄像装置400的镜头卡口402的卡口侧卡合部406卡合。操作部520通过相对于底座部502滑动而使旋转体513相对于底座部502旋转。在卡口适配器500的连接部510被按压到摄像装置400的镜头卡口402的卡口面的状态下，如图9A所示，当操作部520相对于底座部502向第一方向590滑动时，旋转体513向第一方向590旋转，使得适配器侧卡合部512与摄像装置400的镜头卡口402的卡口侧卡合部406卡合。在卡口适配器500的连接部510安装于摄像装置400的镜头卡口402的卡口面的状态下，如图9B所示，当操作部520相对于底座部502向与第一方向590相反的第二方向592滑动时，旋转体513向第二方向592旋转，使得适配器侧卡合部512与摄像装置400的镜头卡口402的卡口侧卡合部406的卡合被解除。由此，从摄像装置400拆下卡口适配器500。
图10是拆卸了一部分零件的卡口适配器500的外观立体图。在图10中，拆卸了保持部516以及操作部520的盖子。操作部520包括锁定机构530，锁定机构包括通过卡止于保持部516而防止操作部520相对于底座部502相对地移动的卡止部532。保持部516在与卡止部532的一端侧的前端部分533对应的外周侧面上包括槽，通过前端部分533嵌入槽，防止操作部520相对于底座部502滑动。卡口适配器500还包括检测部540，其检测是否处于卡止部532卡止于保持部516的状态。在此，卡止部532卡止于保持部516的状态的概念包括：卡止部532的一部分与保持部516的一部分抵接，且操作部520无法相对于底座部502移动的状态。这个状态的概念包括：例 如卡止部532的前端部分533与保持部516的槽的边缘相抵接，且操作部520无法相对于底座部502移动的状态。这个状态的概念包括：在卡口适配器500不能从摄像装置400拆下的程度下，操作部520能够相对于底座部502移动的状态。进一步而言，这个状态的概念包括：在卡口适配器500的触点部514和摄像装置400的触点部404电连接，且能够经由卡口适配器500的触点部514和摄像装置400的触点部404进行通信的程度下，操作部520能够相对于底座部502移动的状态。
图11及图12示出了锁定机构530的放大立体图。图11示出了卡止部532未将检测部540的开关542按下的状态。图12示出了卡止部532已将检测部540的开关542按下的状态。
锁定机构530还包括支撑板531、按钮535以及弹簧536。支撑板531可移动地支撑按钮535以及卡止部532。按钮535是对卡止部532卡止于保持部516的状态和卡止部532未卡止于保持部516的状态进行切换的切换部的一个示例。按钮535包括从按压面的背面延伸的延伸部537。延伸部537包括引导槽5371。支撑板531包括向延伸部537一侧突出的引导柱534。引导柱534插入到引导槽5371中，引导延伸部537朝长度方向移动。卡止部532在中央附近包括通孔5321。卡止部532可以通过从支撑板531突出的销可旋转地支撑在支撑板531上。
当按下按钮535时，延伸部537的端部按压卡止部532。卡止部532被延伸部537按下，并以通孔5321为中心旋转。由此，卡止部532的前端部分533从按下检测部540的开关542的状态移动到未按下的状态。在处于卡止部532卡止于保持部516的状态的情况下开关542在被卡止部532按下，检测出卡止部532卡止于保持部516的状态。在处于卡止部532未卡止于保持部516的状态的情况下，开关542不被卡止部532按下，检测出卡止部532未卡止于保持部516的状态。
弹簧536与支撑板531和卡止部532连接。在按钮535被按下而卡止部532未按下开关542的状态下，弹簧536伸长。当从按钮535被按下的状态变为未被按下的状 态时，通过弹簧536的复原力，卡止部532变回原来的位置，即卡止部532按下开关542的状态。
在经由卡口适配器500的触点部514和摄像装置400的触点部404进行通信期间，卡口适配器500被从摄像装置400拆下，或在卡口适配器500与摄像装置400之间的连接不完全的状态下经由卡口适配器500的触点部514和摄像装置400的触点部404开始通信，则通信会在中途被中断。由于通信的中断，有可能对摄像系统10的控制等产生影响。
因此，卡口适配器500在开关542为断开状态的情况下，可以判断卡口适配器500与摄像装置400的连接是不完全的，不允许经由卡口适配器500的触点部514和摄像装置400的触点部404进行通信。另一方面，卡口适配器500在开关542为接通状态的情况下，可以判断可靠地进行了卡口适配器500与摄像装置400的连接，允许经由卡口适配器500的触点部514和摄像装置400的触点部404进行通信。
卡口适配器500通过支撑体150固定于主体100。如图13所示，卡口适配器500可以以摄像装置400横拍的姿势即第一姿势通过支撑体150固定于主体100上。另外，如图14所示，卡口适配器500可以以摄像装置400纵拍的姿势即第二姿势通过支撑体150固定于主体100上。
卡口适配器500以万向节300的偏航轴310为中心旋转。偏航轴310不一定与摄像装置400所包括的图像传感器430的中心431一致。而且，无论摄像装置400处于横拍的姿势还是纵拍的姿势，支撑体150的高度h都是恒定的。如果假设卡口适配器500在图像传感器430的中心431处旋转，来设计卡口适配器500的大小，则在摄像装置400处于横拍姿势和纵拍姿势这两种情况下，卡口适配器500固定于支撑体150的固定面与主体100固定于支撑体150的固定面之间的距离有可能不一致。在这种情况下，有可能无法将卡口适配器500通过支撑体150固定于主体100。因此，优选考虑万向节300的偏航轴310的位置来设计卡口适配器500的形状。
卡口适配器500的形状为：在万向节300以第一姿势(横拍姿势)支撑摄像装置400时卡口适配器500固定于支撑体150的第一固定面561与主体100固定于支撑体150的主体侧固定面140之间的距离，与在万向节300以相对于第一姿势以沿着光轴的偏航轴310为中心旋转后的第二姿势(纵拍)支撑摄像装置400时卡口适配器500固定于支撑体150的第二固定面562与主体侧固定面140之间的距离相同。即，卡口适配器500的形状为：在万向节300以第一姿势支撑摄像装置时卡口适配器固定于支撑体的第一固定面561与偏航轴310之间的距离a，与在万向节300以第二姿势支撑摄像装置400时卡口适配器固定于支撑体的第二固定面562与偏航轴310之间的距离b相同。换言之，卡口适配器500的形状为：从偏航轴310到横拍用的卡口适配器500的第一固定面561的距离a和从偏航轴310到纵拍用的卡口适配器500的第二固定面562的距离b相同。
通过将卡口适配器500的形状设为上述那样的形状，在摄像装置400处于横拍的姿势以及纵拍的姿势这两种的情况下，能够将卡口适配器500通过支撑体150可靠地固定于主体100。
图15示出了摄像系统10的功能块的一个示例。摄像系统10包括主体100、保持机构200、万向节300、镜头卡口400、卡口适配器500、支撑体150以及镜头单元600。
主体100包括主体控制部110、存储器120以及检测传感器132。主体控制部110控制整个摄像系统10。主体控制部110是控制装置的一个示例。主体控制部110可以由CPU或MPU等微处理器、MCU等微控制器等构成。存储器120存储主体控制部110对保持机构200、万向节300、摄像装置400、卡口适配器500和镜头单元600进行控制所需的程序等。存储器120可以为计算机可读记录介质，可以包括SRAM、DRAM、EPROM、EEPROM及USB存储器等闪存中的至少1个。存储器120可以设 置于主体100内部。存储器120可设置成可从主体100上拆卸下来。检测传感器132检测到支撑体150安装在主体100上。
摄像装置400包括图像传感器430、摄像控制部410、存储器420和加速度传感器440。图像传感器430可以由CCD或CMOS构成。图像传感器430拍摄经由镜头单元600成像的光学图像，并将所拍摄的图像数据输出至摄像控制部410。摄像控制部410可以由CPU或MPU等微处理器、MCU等微控制器等构成。摄像控制部410可以根据来自主体控制部110的动作指令来控制摄像装置400。存储器420可以为计算机可读记录介质，可以包括SRAM、DRAM、EPROM、EEPROM及USB存储器等闪存中的至少1个。存储器420储存摄像控制部410对图像传感器430等进行控制所需的程序等。存储器420可以设置于摄像装置400的壳体内部。存储器420可以设置成可从摄像装置400的壳体中拆卸下来。加速度传感器440可以是用于检测摄像装置400的姿势的3轴加速度传感器。
镜头单元600包括多个镜头612、多个镜头驱动部610、镜头控制部620以及存储器630。多个镜头612可以起到变焦镜头、可变焦距镜头及聚焦镜头的作用。多个镜头612中的至少一部分或全部被配置为能够沿着光轴移动。镜头单元600可以是可拆装地设置在摄像装置400上的可更换镜头。镜头驱动部610经由凸轮环等机构构件使多个镜头612中的至少一部分或全部沿着光轴移动。镜头驱动部610可以包括致动器。致动器可以包括步进马达。镜头控制部620按照来自摄像装置400的镜头控制指令来驱动镜头驱动部610，以经由机构构件使1个或多个镜头612沿着光轴方向移动。镜头控制指令例如为变焦控制指令及聚焦控制指令。
卡口适配器500包括适配器控制部570，检测部540以及存储器572。卡口适配器500通过锁销450可拆装地安装在摄像装置400上。卡口适配器500通过锁销574可拆装地安装在镜头单元600上。卡口适配器500包括用于与摄像装置400通信的触点部514。摄像装置400包括用于与卡口适配器500通信的触点部404。卡口适配器 500包括用于与镜头单元600通信的触点部506。镜头单元600包括用于与卡口适配器500通信的触点部632。
检测部540检测是否处于卡止部532卡止于保持部516的状态。即，检测部540检测是卡口适配器500固定到摄像装置400的状态还是卡口适配器500没有固定到摄像装置400的状态。检测部540可以包括物理地切断触点部506与触点部514之间的电连接的开关。
适配器控制部570在检测部540检测到卡止部532卡止于保持部516的状态的情况下，允许经由卡口适配器500的触点部514和摄像装置400的触点部404进行通信。适配器控制部570在检测部540未检测到卡止部532卡止于保持部516的状态的情况下，不允许经由卡口适配器500的触点部514和摄像装置400的触点部404进行通信。由此，能够防止在经由卡口适配器500的触点部514和摄像装置400的触点部404进行通信期间，卡口适配器500被从摄像装置400拆下，或在卡口适配器500与摄像装置400之间的连接不完全的状态下经由卡口适配器500的触点部514和摄像装置400的触点部404开始通信时，通信被切断而对摄像系统10的控制等产生影响。适配器控制部570是通信控制部的一个示例。
适配器控制部570从控制图像传感器430的摄像控制部410接收符合第一通信标准的第一控制信号，并将第一控制信号转换为符合第二通信标准的第二控制信号并发送给镜头单元600。适配器控制部570是转换部的一个示例。即使在摄像装置400的通信标准与镜头单元600的通信标准不同的情况下，适配器控制部570也能够根据通信标准对控制信号进行转换，从而摄像装置400与镜头单元600可以相互通信。
适配器控制部570可以由CPU或MPU等微处理器、MCU等微控制器等构成。存储器572存储对适配器控制部570进行控制所需的程序等。存储器572可以为计算机可读记录介质，可以包括SRAM、DRAM、EPROM、EEPROM及USB存储器等 闪存中的至少1个。存储器572可以设置在卡口适配器500的内部。存储器572可以设置为能够从卡口适配器500中拆卸下来。
