One day, cameras may be able to capture less data but produce images that look just as good as a traditional photo. Bell Labs is the latest to attempt such a feat, and it's doing so while eschewing another major camera standby, the lens. The laboratory has developed a single-pixel camera that only uses a series of transparent openings to capture its image, without any glass to direct the light. The system uses a technology called "compressive sensing," which is still in its early stages of study...
