    • 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。
