A gigapixel image is a digital image bitmap composed of one billion (109) pixels (picture elements), 250 times the image captured by a mid-range (4 megapixel) digital camera. Current technology for creating such very high-resolution images involves making mosaics of a large number of high-resolution digital photographs, or using World War II spycam technology to create a film negative as large as 9"×12" (23 cm×30 cm), which is then scanned with a high-end film scanner. Recent developments have demonstrated the practicality of developing scanning cameras capable of creating a gigapixel image in a single sweep of a scene.
