先拍照，后对焦【一个高科技创业故事】
|||
美国的Lytro推出了全球第一款突破基本摄影原理的“光场”相机。“光场摄影”的突破性在于，它利用由数万个微透镜组成的阵列捕捉记录拍摄对象周围所有方向的光线信息，从而可以实现“先拍摄后对焦”。
光场相机的好处在于，拍摄者可以根据个人需要和喜好来选择编辑出自己最终想要看到的照片。也就是说，拍照的时候你不必去对焦取景什么的，先把数据搞回家，慢慢琢磨，想什么焦距就什么焦距——这一点很有意思。
这家公司的创始人是斯坦福大学的博士，他博士期间研究的就是light field technology，我也没仔细看到底什么原理；但这位大侠博士研究的不错；毕业后就自己玩这种新相机了。
其实之前他就开始策划宣传了，最近是打算出正式产品。
英文消息：
Lytro will introduce the first light field camera that allows consumers to instantly capture interactive, living pictures and then focus them AFTER they are taken.
Before starting Lytro, Ren was on the fast path to fulfilling his childhood dream of becoming a professor. In fact, his seminal Ph.D. research on light field technology earned the field’s top honor, the ACM Doctoral Dissertation Award for best thesis in computer science and engineering, as well as Stanford University’s Arthur Samuel Award for Best Ph.D. Dissertation. The entrepreneurial spark came when Ren purchased his first DSLR camera and saw the potential to apply light field technology to capture pictures in addition to image generation. As a result, instead of continuing on a purely academic path, Ren decided to apply and extend his theoretical work by making light field cameras that everyone can use. That’s how the Lytro picture revolution began.
When the company originally received funding, Ren was running the business solo. Ren and a core team made breakthrough engineering innovations, setting a strong foundation for the world-class crew he’s now leading to produce light field cameras that make groundbreaking living pictures. The ambition and persistence that characterize Ren’s career are also evident in his hobbies – an avid rock climber, he is constantly striving to reach new heights. Ren holds a Ph.D. in computer science and a B.S. in mathematical and computational science from Stanford University.
