对焦速度

但你需要记住的是缓慢的对焦速度总是在暗光条件下显得尤其明显。

The slow focusing speed is most noticeable in lower light situations .

它可以让自动对焦速度更快并改善低光成像效果。

It can make autofocus faster and improve low-light photography .

基于离焦估计的对焦速度的提高方法

Method of Improving Autofocus Speed Based on Defocus Estimation

在自动聚焦系统中，对焦窗口的选择直接影响对焦的速度和准确性。

In automatic focusing system , the focusing window directly affects the speed and veracity of auto-focusing .

该算法大大减少了自动对焦所需要采集的图像数量，对焦速度、精度以及鲁棒性均有明显的提高。

This algorithm decreases greatly the number of images that are acquired for autofocusing , and increases the speed , accuracy and robustness of the microscopic autofocusing system .

在影像测量仪的自动对焦系统中，比其他方法具有更快的对焦速度和更高的对焦准确度，且具有良好的稳定性。

The improved function , with good stability , has faster focusing speed and higher focusing accuracy than other methods in the auto-focusing system of image measurement instrument .

二者在保持对焦评价曲线灵敏度的同时，可以有效地降低计算量，加快对焦速度。

Keeping acuity of focus measure curve , new approaches reduced run-time and improved the speed of focus .
