Chair of innovative-camera company discusses technology, licensing

Macworld : A California company called Lytro has developed a revolutionary new camera that allows users to focus an image after it’s been shot. Lytro uses a microlens array to capture four-dimensional light-field information. With software and processing, that information can be used to improve the image later. In a Q&A with Lytro’s executive chair Charles Chi, Tim Moynihan asks him about the light-field technology, best types of sensors, and licensing possibilities with camera and camera-phone manufacturers.
