There is too much in the world to see. Digital cameras capture all that is within their field of vision, storing richly detailed images in large files. But for many purposes, they don’t have to. When we’re driving, we don’t need to know the license plates of all the cars around us, just their general shapes and positions. RedEye, a new image processing architecture, wants cameras to process images first, and then store only the relevant details. The goal: reducing the amount of data it takes to store images, so a wearable computer could watch what a human watches, continuously.
