    • A zoom lens focusing apparatus for a camera includes a zoom ring for adjusting a zoom lens section of the camera to different magnifications by moving a movable lens assembly therein forward and backward. A cam mechanism couples the zoom ring to the movable lens assembly, so that a change in the focal length of the zoom lens section caused by rotation of the zoom ring, is a logarithmic function of the angle of rotation of the zoom ring. A master lens section of the camera also has a movable lens assembly therein which is movable forward and backward by a driving device. The position of the zoom ring is detected while the movable lens of the zoom lens section moves backward or forward, and a sampling pulse generating circuit produces a pulse corresponding to the position of the zoom ring. A voltage which changes corresponding to the distance of the subject from the camera is applied to a charge-and-discharge circuit and the output thereof is held in a sample and hold circuit. The driving device is driven by the output held to drive the movable lens assembly of the master lens section to thereby attain focusing.
    • 用于照相机的变焦镜头聚焦装置包括:变焦环,用于通过将可移动透镜组件向前和向后移动来将照相机的变焦透镜部分调整为不同的倍率。 凸轮机构将变焦环连接到可移动透镜组件,使得由变焦环的旋转引起的变焦透镜部分的焦距的变化是变焦环的旋转角的对数函数。 相机的主镜片部分还具有可移动的透镜组件,其中可移动的透镜组件可由驱动装置向前和向后移动。 当变焦镜头部分的可移动镜头向后或向前移动时,检测变焦环的位置,并且采样脉冲发生电路产生对应于变焦环的位置的脉冲。 将对应于被摄体距相机的距离变化的电压施加到放电电路,其输出保持在采样和保持电路中。 驱动装置被保持的输出驱动,以驱动主透镜部分的可移动透镜组件,从而获得聚焦。

    • A video signal produced through a shooting operation of a camera is sent to a motion detecting unit which detects a motion included in the video signal to set an area of the motion as a space motion area and inputs information of the area to a distance determination circuit which calculates distance between the motion area and the camera by use of a parallax signal produced from stereo cameras disposed in the camera to send information of the space motion area and the distance to a mask determination circuit. The mask determination circuit conducts a comparison between the space motion area information and the space mask area information and between the distance information of the motion area and that of the space mask area, and resultantly compares three-dimensional positions between the detected motion and the mask to determine a position relationship therebetween.
    • 通过照相机的拍摄操作产生的视频信号被发送到运动检测单元,该运动检测单元检测包括在视频信号中的运动,以将运动的区域设置为空间运动区域,并将该区域的信息输入到距离确定电路 其通过使用设置在摄像机中的立体摄像机产生的视差信号来计算运动区域和摄像机之间的距离,以发送空间运动区域的信息和到掩模确定电路的距离。 掩模确定电路进行空间运动区域信息和空间掩模区域信息之间以及运动区域的距离信息与空间掩模区域的距离信息之间的比较,并且结果将比较检测到的运动与掩模之间的三维位置 以确定它们之间的位置关系。
