图1是示出本实施方式所涉及的摄像装置100的外观立体图的一个示例的图。图2是示出本实施方式所涉及的摄像装置100的功能块的图。
摄像装置100包括摄像部102及镜头部200。摄像部102包括图像传感器120、摄像控制部110及存储器130。图像传感器120可以由CCD或CMOS构成。图像传感器120将通过变焦镜头211以及聚焦镜头210成像的光学图像的图像数据输出至摄像控制部110。摄像控制部110可以由CPU或MPU等微处理器、MCU等微控制器等构成。存储器130可以是计算机可读记录介质，也可以包括诸如SRAM、DRAM、EPROM、EEPROM和USB存储器等闪存中的至少一种。存储器130储存摄像控制部110对图像传感器120等进行控制所需的程序等。存储器130可以设置于摄像装置100的壳体内部。存储器130可以设置成可从摄像装置100的壳体上拆卸下来。
摄像部102还可以包括指示部162及显示部160。指示部162是从用户处接受对摄像装置100的指示的用户界面。显示部160显示由图像传感器120所摄像的图像、摄像装置100的各种设定信息等。显示部160可以由触控面板组成。
镜头部200包括聚焦镜头210、变焦镜头211、镜头驱动部212、镜头驱动部213以及镜头控制部220。聚焦镜头210和变焦镜头211可以包括至少一个镜头。聚焦镜头210和变焦镜头211的至少一部分或全部被配置为能够沿着光轴移动。镜头部200可以是被设置成能够相对摄像部102拆装的可更换镜头。镜头驱动部212经由凸轮环、引导轴等机构构件使聚焦镜头210的至少一部分或全部沿着光轴移动。镜头驱动部213经由凸轮环、引导轴等机构构件使变焦镜头211的至少一部分或全部沿着光轴移动。镜头控制部220按照来自摄像部102的镜头控制指令来驱动镜头驱动部212和镜头驱动部213中的至少一个，并经由机构构件使聚焦镜头210和变焦镜头211中的至少一个沿着光轴方向移动，以执行变焦动作和聚焦动作中的至少一个。镜头控制指令例如为变焦控制指令及对焦控制指令。
镜头部200还包括存储器240、位置传感器214以及位置传感器215。存储器240对由镜头驱动部212和镜头驱动部213驱动的聚焦镜头210和变焦镜头211的控制值进行存储。存储器240可以包括SRAM、DRAM、EPROM、EEPROM及USB存储器等闪存中的至少一个。位置传感器214检测聚焦镜头210的位置。位置传感器214可以检测当前的聚焦位置。位置传感器215检测变焦镜头211的位置。位置传感器215可以检测变焦镜头211的当前的变焦位置。
镜头部200包括光学式图像抖动校正机构(OIS)。更具体而言，镜头部200包括图像抖动校正用镜头231和镜头232、镜头驱动部233、镜头驱动部234、位置传感器235、位置传感器236以及振动传感器250。振动传感器250可以是检测摄像装置100振动的陀螺仪传感器。振动传感器250可以是检测摄像装置100振动的加速度传感器。陀螺仪传感器检测例如角度抖动和旋转抖动。加速度传感器检测例如X方向和Y方向的位移抖动。即便是陀螺仪传感器，也可以将角度和旋转转换为X方向的分量和Y方向的分量。即便加速度传感器，也可以将X方向和Y方向的位移抖动转换为角度抖动和旋转抖动。振动传感器250可以将加速度传感器和陀螺仪传感器组合。镜头驱动部233使镜头231沿与光轴相交的方向移动。镜头驱动部233可以使镜头231沿与光轴垂直的方向移动。镜头驱动部233可以包括音圈电机。镜头驱动部234使镜头232沿与光轴相交的方向移动。镜头驱动部234可以使镜头232沿与光轴垂直的方向移动。镜头驱动部234可以包括音圈电机。
位置传感器235检测镜头231的位置。位置传感器235可以检测镜头231与光轴垂直方向的位置。位置传感器235可以输出镜头231与光轴垂直方向的位置作为显示镜头231振动的振动信号。位置传感器236检测镜头232的位置。位置传感器236可以检测镜头232与光轴垂直方向的位置。位置传感器236可以输出镜头232与光轴垂直方向的位置作为显示镜头232振动的振动信号。
镜头部200是图像抖动校正装置的一个示例。镜头控制部220从振动传感器250获取显示振动第一振动信号，并基于第一振动信号，通过镜头驱动部233和镜头驱动 部234，使镜头231和镜头232沿与光轴相交的方向振动，从而校正图像抖动。图像传感器120拍摄通过变焦镜头211、聚焦镜头210、镜头232以及镜头232成像的图像。
镜头控制部220通过镜头驱动部234使镜头232以第一频带的频率振动，通过镜头驱动部233使镜头231以比第一频带更高的第二频带的频率振动，从而校正图像抖动。
由于单独驱动图像抖动校正用镜头231和镜头232，由此能够使分别驱动镜头231和镜头232的镜头驱动部233和镜头驱动部234小型化。通过在不同的频带驱动镜头231和镜头232，能够降低由位置传感器235和位置传感器236检测出的镜头231和镜头232的位置的误差对图像抖动校正的影响。此外，通过在不同的频带驱动镜头231和镜头232，能够在较宽频带对图像抖动进行校正。
镜头231可以比镜头232轻。镜头231的直径可以比镜头232的直径小。通过减小在相对较高频带进行驱动的镜头231的尺寸，能够降低镜头驱动部233消耗的电力。
镜头控制部220可以通过滤波器从来自振动传感器250的振动信号中提取第一频带的振动信号和第二频带的振动信号。镜头控制部220可以基于第一频带的振动信号，通过镜头驱动部234使镜头232以第一频带的频率振动，基于第二频带的振动信号，通过镜头驱动部233使镜头231以第一频带的频率振动。
镜头控制部220可以基于来自振动传感器250的振动信号，通过镜头驱动部233使镜头231以第二频带的频率振动。进而，镜头控制部220可以基于由位置传感器235检测出的显示镜头231振动的振动信号与来自振动传感器250的振动信号之差，通过镜头驱动部234使镜头232以第一频带的频率振动。
镜头231的灵敏度可以与镜头232的灵敏度不同。灵敏度显示镜头移动量和由镜头产生的图像抖动校正量之间的比值。与灵敏度低的镜头相比，灵敏度高的镜头对应镜头移动量的图像抖动校正量更大。也就是说，与灵敏度低的镜头相比，灵敏度高的镜头通过较小的移动得到更大的校正图像抖动的效果。镜头232的灵敏度可以比镜头231的灵敏度低。镜头控制部220可以使灵敏度高的镜头231以第二频带的频率振动，使灵敏度低的镜头232以比第二频带更低的第一频带的频率振动。
镜头控制部220可以基于来自振动传感器250的振动信号，通过镜头驱动部233使灵敏度高的镜头231以第二频带的频率振动，基于由位置传感器235检测出的显示镜头231振动的振动信号与来自振动传感器250的振动信号之差，通过镜头驱动部234使灵敏度低的镜头232以第一频带的频率振动。也就是说，镜头控制部220基于来自振动传感器250的振动信号，先使灵敏度高的镜头231振动，再通过使灵敏度低的镜头232振动来校正不能由镜头231消除的图像抖动。
驱动镜头231的镜头驱动部233可以包括压电元件或者超声波电机来代替音圈电机。通过利用压电元件或者超声波电机，能够实现小型化。
图3是示出光学式图像抖动校正机构的框图的一个示例的图。图3的框图示出以下示例：从来自振动传感器250的振动信号中提取第一频带的振动信号和第二频带的振动信号而驱动各自的音圈电机2312及2322。
将来自振动传感器250的振动信号输入至滤波器252。滤波器252输出显示图像抖动的频率分量的振动信号。如图4和图5所示，PID2311从来自滤波器252的振动信号500中提取显示第二频带振动的振动信号502，并且PID2311基于显示第二频带振动的振动信号502，驱动音圈电机2312而使镜头231振动。位置传感器235输出显示镜头231振动的振动信号。通过将来自滤波器252的振动信号与来自位置传感器235的振动信号的差分振动信号输入至PID2311从而执行反馈控制。
同样地，如图4和图5所示，PID2321从来自滤波器252的振动信号500中提取显示第一频带振动的振动信号501，并且PID2321基于显示第一频带振动的振动信号501，驱动音圈电机2322而使镜头232振动。位置传感器236输出显示镜头232振动的振动信号。通过将来自滤波器252的振动信号与来自位置传感器236的振动信号的差分振动信号输入至PID2321，从而执行反馈控制。滤波器252可以从振动信号500中提取显示第一频带的振动的振动信号501和显示第二频带的振动的振动信号502。
图6是示出光学式图像抖动校正机构的框图的另一个示例的图。图6的框图示出以下示例：基于来自振动传感器250的振动信号，使镜头231以第二频带的频率振动，将不能由镜头231校正的图像抖动通过使镜头232以第一频带的频率振动进行校正。
将来自振动传感器250的振动信号输入至滤波器252。滤波器252输出显示图像抖动的频率分量的振动信号。如图7所示，PID2311基于来自滤波器252的振动信号511驱动音圈电机2312，从而使镜头231振动。位置传感器235输出显示镜头231振动的振动信号512。如图8所示，将来自滤波器252的振动信号511与来自位置传感器235的振动信号512的差分振动信号513输入至PID2321和PID2311。PID2321基于差分振动信号513驱动音圈电机2322，从而使镜头232振动。位置传感器236输出显示镜头232振动的振动信号。通过将差分振动信号513与来自位置传感器236的振动信号的差分振动信号输入至PID2321，从而执行反馈控制。
根据本实施方式，能够使惯性矩相对较小的小型镜头231以高频率振动，使惯性矩相对较大的大型镜头232以低频率振动。由此能够降低电力消耗，并提高图像抖动的校正性能。
图9是示出可全部或部分地体现本发明的多个方面的计算机1200的一个示例。安装在计算机1200上的程序能够使计算机1200作为与本发明的实施方式所涉及的装置相关联的操作或者该装置的一个或多个“部”而起作用。或者，该程序能够使计算机1200执行该操作或者该一个或多个“部”。该程序能够使计算机1200执行本发明的实施方式所涉及的过程或者该过程的阶段。这种程序可以由CPU1212执行，以使计算机1200执行与本说明书所述的流程图及框图中的一些或者全部方框相关联的指定操作。

通信接口1222通过网络与其他电子装置通信。硬盘驱动器可以存储计算机1200内的CPU1212所使用的程序及数据。ROM1230在其中存储运行时由计算机1200执行的引导程序等、和/或依赖于计算机1200的硬件的程序。程序通过CR-ROM、USB存储器或IC卡之类的计算机可读记录介质或者网络来提供。程序安装在也作为计算机可读记录介质的示例的RAM1214或ROM1230中，并通过CPU1212执行。这些程序中记述的信息处理由计算机1200读取，并引起程序与上述各种类型的硬件资源之间的协作。可以通过根据计算机1200的使用而实现信息的操作或者处理来构成装置或方法。
例如，当在计算机1200和外部装置之间执行通信时，CPU1212可执行加载在RAM1214中的通信程序，并且基于通信程序中描述的处理，命令通信接口1222进行通信处理。通信接口1222在CPU1212的控制下，读取存储在RAM1214或USB存储器之类的记录介质内提供的发送缓冲区中的发送数据，并将读取的发送数据发送到网络，或者将从网络接收的接收数据写入记录介质内提供的接收缓冲区等中。
此外，CPU1212可以使RAM1214读取USB存储器等外部记录介质所存储的文件或数据库的全部或者需要的部分，并对RAM1214上的数据执行各种类型的处理。接着，CPU1212可以将处理过的数据写回到外部记录介质中。
可以将各种类型的程序、数据、表格及数据库之类的各种类型的信息存储在记录介质中，并接受信息处理。对于从RAM1214读取的数据，CPU1212可执行在本公开的各处描述的、包括由程序的指令序列指定的各种类型的操作、信息处理、条件判断、条件转移、无条件转移、信息的检索/替换等各种类型的处理，并将结果写回到RAM1214中。此外，CPU1212可以检索记录介质内的文件、数据库等中的信息。例如，在记录介质中存储具有分别与第二属性的属性值相关联的第一属性的属性值的多个条目时，CPU1212可以从该多个条目中检索出与指定第一属性的属性值的条件相匹配的条目，并读取该条目内存储的第二属性的属性值，从而获取与满足预定条件的第一属性相关联的第二属性的属性值。
以上描述的程序或者软件模块可以存储在计算机1200上或者计算机1200附近的计算机可读存储介质上。另外，连接到专用通信网络或因特网的服务器系统中提供的诸如硬盘或RAM之类的记录介质可以用作计算机可读存储介质，从而可以经由网络将程序提供给计算机1200。
以上使用实施方式对本发明进行了说明，但是本发明的技术范围并不限于上述实施方式所描述的范围。对本领域普通技术人员来说，显然可对上述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。
应该注意的是，权利要求书、说明书以及说明书附图中所示的装置、系统、程序以及方法中的动作、顺序、步骤以及阶段等各项处理的执行顺序，只要没有特别明示“在...之前”、“事先”等，且只要前面处理的输出并不用在后面的处理中，则可以任意顺序实现。关于权利要求书、说明书以及说明书附图中的操作流程，为方便起见而使用“首先”、“接着”等进行了说明，但并不意味着必须按照这样的顺序实施。
