    • An image capture device (10) is provided which performs a combination of digital and optical zoom techniques to achieve high levels of zoom without sacrificing image quality. In a first embodiment, an opto-digital lens system is provided including a wide angle lens (20) and a normal lens (25), the transition between which is smoothed using moderate digital zooming. Starting from the wide angle fixed optical length, the processor (40) may be used to digitally zoom the captured image. At a predetermined point during the digital zoom operation, the normal lens (25) is placed into the optical path and the processor (40) again digitally zooms the beginning.
    • 提供了一种图像捕获设备(10),其执行数字和光学变焦技术的组合以实现高水平的变焦而不牺牲图像质量。 在第一实施例中,提供了一种光数字透镜系统,其包括广角镜头(20)和普通透镜(25),使用适度的数字变焦平滑其间的转换。 从广角固定光学长度开始,处理器(40)可用于数字地缩放拍摄图像。 在数字变焦操作期间的预定点,普通透镜(25)被放置在光路中,并且处理器(40)再次数字地缩放开始。

    • A parallax compensation system and method is provided for a camera including an independent viewfinder. For close focus pictures, the camera's taking lens is shifted towards the viewfinder. In one embodiment, for far focus pictures the camera's taking lens is moved away from the viewfinder and is not centered on the image recording medium axis. The lens shifting is accomplished by mounting the taking lens eccentrically in a lens barrel. Rotation of the lens barrel shifts the taking lens towards the independent viewfinder for close focus shots. In one embodiment, the viewfinder axis is tilted towards the taking lens to help iliminate parallax in close focus pictures.
    • 为包括独立取景器的照相机提供视差补偿系统和方法。 对于近距离对焦的照片,相机的拍摄镜头将朝向取景器移动。 在一个实施例中,对于远焦点图像,相机的拍摄镜头被移动远离取景器并且不以图像记录介质轴为中心。 透镜移位通过将拍摄镜头偏心地安装在镜筒中来实现。 透镜镜头的旋转将拍摄镜头朝向独立取景器移动,以进行近距离对焦拍摄。 在一个实施例中,取景器轴线朝着拍摄镜头倾斜以帮助在近距离对焦的图像中显示视差。
