    • The present invention provides a novel camera apparatus which can be discretely split into two parts; a lens barrel unit and a lens-barrel-support unit which allows the lens barrel unit to freely turn its direction. A built-in angular rate detector detects a swinging movement of the lens barrel unit, whereas a position detector detects a position relationship between the lens barrel unit and the support unit. An operator unit storing programs controls a drive operation of an actuator that generates a specific amount of torque between the lens barrel unit and the support unit to reduce an output from a system controller unit so that swinging symptom of video picture caused by the swinging movement of the video camera can be eliminated. In addition to this primary function, the operator unit also executes its secondary function, in which the operator unit first detects intention of a camera operator by identifying a varied position relationship between the lens barrel unit and the support unit when one intentionally changes an aimed direction of the video camera and then the operator unit controls the driving of the actuator so that the lens barrel unit can correctly face the aimed direction.
    • 本发明提供了一种可以离散地分成两部分的新型相机装置。 镜筒单元和透镜镜筒支撑单元,其允许镜筒单元自由地转动其方向。 内置角速率检测器检测镜筒单元的摆动运动,而位置检测器检测镜筒单元与支撑单元之间的位置关系。 存储程序的操作单元控制在镜筒单元和支撑单元之间产生特定量的扭矩的致动器的驱动操作,以减少系统控制器单元的输出,使得由摆动运动引起的视频图像的摆动症状 可以消除摄像机。 除了这个主要功能之外,操作单元还执行其次要功能,其中操作者单元首先通过识别镜筒单元和支撑单元之间的变化的位置关系来检测相机操作者的意图,当有意改变目标方向 然后操作单元控制致动器的驱动,使得镜筒单元能够正确地朝向目标方向。
