Computational photography

A cutaway view showing some of the optical and electronic components in a Canon 5D - one of the most capable prosumer digital cameras (image from Canon USA). Stanford's multi-camera array. In the arrangement shown above, 100 VGA cameras are combined to create a 30 megapixel virtual video camera. By inserting a microlens array into a conventional handheld camera, one can create a plenoptic camera, which can record a light field in a single snapshot. The photographs produced by a plenoptic camera can be refocused after they are captured, and the viewpoint can be moved. Click above for an example of digital refocusing. Dual photography lets us read a hidden playing card from its reflection in the page of a book. The card's face is shown at lower-right.
