gigapixel

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.[1][2]
