"骁龙"双摄像头:先拍照,后对焦

你所看到的世界是立体的,现在,智能相机也一样了。人的大脑捕捉并整合左、右眼的影像信息,然后将信息合成图像。现在,借助带双影像信号处理器(ISP)的Qualcomm骁龙处理器,就可以实现相似的成像效果:在骁龙处理器的帮助下,制造商可以在设备背面安装两个摄像头,分别配有一个ISP。我们看到,一些智能手机已经具有这样的功能了,包括ZTE Axon、Axon Pro、HTC One M8HTC Butterfly 3、奇酷手机旗舰版和尊享版等。

智能手机搭载的骁龙处理器使用双摄像头采集信息,从而提供更多新颖、充满创意的摄影选择。处理器采用双视频流,可将拍摄的多个图片转化为深度信息,这与大脑感知深度的方式非常相似,因为大脑从左右眼接收的信息会略有差别。一旦有了这些深度信息,新特性也就显现出来:

快速自动对焦:利用深度信息,骁龙处理器可以快速精确地设定相机焦平面,因此照片非常清晰。

重新对焦:骁龙处理器可以给两个摄像头设置不同的焦点,因此,在拍摄瞬间,两个摄像头就捕捉到了不同的焦点和深度信息。这样一来,您就可以先拍摄,再选择焦点。

图像细化: 深度映射使骁龙处理器能够理解前景和背景、风景和人物。您在拍摄照片之后,可以调整这些聚焦面。 

有了这些强大的新功能,您手握骁龙芯智能手机,便可以拍摄出乎意料且前所未有的精彩照片。
