哪位高手请帮我翻译一下论文摘要，非常感谢!

本文针对数码相机自动对焦系统的设计要求,对自动对焦的基本理论与方法、对焦评价函数及其选择、对焦窗口的规划与自动选择、自动对焦的反馈控制进行了深入研究。
在研究数码相机结构、对焦原理与自动对焦技术的基础上，分析了对焦评价函数特别是常用梯度函数的特点，从隔行扫描间隔选取像素与设定大小阈值、用绿色分量值替代灰度值和粗扫细扫分别选取不同评价函数等三个方面对梯度函数进行了修正。
提出了对焦窗口规划，论述了选用19个对焦窗口的可行性，并就近距离物体优先的对焦窗口自动选择提出了实现方法。
通过对峰值搜索方法的研究，分析了传统爬山算法的不足，提出了粗扫与细扫相结合、自适应变步长的改进型爬山算法，探讨了自动对焦的反馈控制。

In this paper, a digital camera autofocus system design requirements, the autofocus of the basic theory and methods, focusing evaluation function and its selection, focus of planning and automatic window selection, autofocus feedback control carried out in-depth research.

Research at the structure of a digital camera, autofocus Focusing Principle and technology, based on the analysis of the focusing evaluation function in particular are commonly used features of the gradient function, from the interlaced scanning interval to select the size of pixels and set the threshold, with a green sub-Money alternative gray value and fine-coarse sweep sweep separately select a different function, such as evaluation of three aspects of the gradient function has been amended.

Focus window proposed planning, discussed the selection of 19 focus window feasibility and priority of focus close-up objects in a window automatically select a method of implementation.

By the peak search method of research, an analysis of the shortcomings of traditional climbing algorithm proposed coarse sweep sweep with a combination of small, adaptive variable step size improved climbing algorithm of feedback control of the autofocus.
