在一实施例中，控制模块40包括分别与镜头组件20电性连接的对焦模块42和芯片模块41，对焦模块42根据测距组件30发送的距离信息调节镜头组件20的焦距。镜头组件20拍摄并向芯片模块41发送图像信息，芯片模块41用于处理图像信息。可选地，对焦模块42采用AF(Automatic Focus，自动对焦)系统，芯片模块41采用ISP(Image Signal Processor，图像处理器)芯片模块41。
对焦模块42与测距组件30相互电性连接，测距组件30根据检测介质的收发数据获取距离信息，该距离信息发送至对焦模块42。对焦模块42根据该距离信息调整镜头21的焦距，以使镜头21能采集被摄物体适宜的图像信息。图像传感器22将相应地光线转换成电信号形式的图像信息，该电信号传递至芯片模块41。芯片模块41根据电信号生成相应的图形数据，图形数据通过显示模块显示。如图形数据通过设备自带的显示屏或可传输至可识别设备上，以方便用户识别，用户体验好。
在一实施例中，相机主体10设为框架结构，如相机主体10设为数码相机的外壳、摄像设备的外壳、手机的外壳及其他拍摄设备的框架形外壳。在设备主体上设有拍摄孔，镜头组件20的轴线与拍摄孔的轴线重合。在设备主体上还设有至少一个探测孔，测距组件30通过至少一个探测孔发射及接收检测介质，信号阻挡少，测距效果好。
