    • A lens barrel includes a lens barrel part generally cylindrical about an optical axis, a first driving part arranged to serve as a drive source for executing a focusing action, a second driving part arranged to serve as a drive source for executing a zooming action and a third driving part arranged to serve as a drive source for executing an aperture reducing action. The first, second and third driving parts are disposed externally of the lens barrel part and circumferentially of the optical axis, and may have arcuate outer surfaces which may not extend beyond the perimeter of the lens barrel part.
    • 透镜镜筒包括通常围绕光轴圆柱形的透镜镜筒部分,布置成用作用于执行聚焦动作的驱动源的第一驱动部件,布置成用作执行缩放动作的驱动源的第二驱动部件和 第三驱动部件布置成用作用于执行孔径减小动作的驱动源。 第一驱动部件,第二驱动部件和第三驱动部件设置在镜筒部分的外侧并且在光轴的周向设置,并且可以具有弓形的外表面,该外表面可以不延伸超过透镜镜筒部分的周边。

    • Disclosed is a device which is mounted on a vehicle, and captures a rear region of a vehicle and a blind spot region outside of a viewing range of a side mirror adjacent to the rear region of the vehicle. A captured image is subjected to image processing so that the blind spot region on the captured image is compressed. The image after subjected to the image processing is displayed so as to be visible to a driver. The blind spot region on the captured image is compressed so that a sudden change of position of a object in a horizontal direction on the captured image is suppressed, as against a change of distance from the vehicle to the object. Compression is performed so that the ratio of transition of position of the object in the horizontal direction on the captured image to transition of distance from the vehicle to the object is substantially the same as the ratio of transition of position of the object in the horizontal direction in the side mirror to transition of distance from the vehicle to the object. The phenomenon of the object's appearance as if the object suddenly accelerates in the vicinity of the vehicle is avoided.
    • 公开了一种安装在车辆上的装置,并且捕获车辆的后部区域和邻近车辆后部区域的侧镜的观察范围之外的盲点区域。 拍摄的图像经受图像处理,使得捕获的图像上的盲点区域被压缩。 显示经过图像处理后的图像,以便对驾驶员可见。 被捕获的图像上的盲点区域被压缩,从而抑制了被拍摄图像上的物体在水平方向上的位置的突然变化,与对车辆的距离的变化相对应。 进行压缩,使得物体在水平方向上的位置的转变与捕获的图像之间的距离与从车辆到物体的距离的转变的比率基本上与物体在水平方向上的位置的转变的比率相同 在侧视镜中,从车辆到物体的距离过渡。 避免了在车辆附近突然加速物体的外观现象。
