A gigapixel image is a digital image bitmap composed of one billion (109) pixels (picture elements), 1000 times the information captured by a 1 megapixel digital camera. Current technology for creating such very high-resolution images usually involves either making mosaics of a large number of high-resolution digital photographs or using a film negative as large as 12" Ã 9" (30 cm Ã 23 cm) up to 18" Ã 9" (46 cm Ã 23 cm), which is then scanned with a high-end large-format film scanner with at least 3000 dpi resolution. Only a few cameras are capable of creating a gigapixel image in a single sweep of a scene, such as the Pan-STARRS PS1 and the Gigapxl Camera.
If you feel very proud of your iPhone’s 8Megapixel camera or your high resolution DSLR, you might want to consider what a camera capable of taking photos with gigapixel resolution implies. Researchers at Duke University and the University of Arizona thought this through, and managed to devise a 50 gigapixel camera. Here’s Paris in 26 Gigapixels [...]
