Template-matching method is used to decide whether the deformed and rotated template is contained in the image, the decision function is the adaptability function (AF) of GA.

用模板匹配法判定图像中是否含有形变旋转后的模板，判定函数就是遗传算法的适应度函数。

The camera's AF sensors require some details in the image to determine the phase difference. It's harder for the camera to find focus when the light is dim or there is little subject detail.

相机的自动对焦感应点需要一些影像细节来确定相位差，光线不足或者物体细节不足都会导致聚焦困难。

The multi-tasking image-processing Venus Engine enables beautiful image recording and Sonic Speed AF (Auto Focus) combined with a quick camera start-up time to offer a high-speed response time to ensure users can capture even the most spur-of-the-moment photo opportunities.

ENGADGET: Panasonic's Lumix line gets a lot more crowded

Tapping in on the chosen subject within the frame of the cameras' LCD monitor instantly focuses the subject and automatically triggers the shutter for instantaneous in-focus image capture thanks to the Touch AF Shutter function.
