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. Current technology for creating such very high-resolution images usually involves either making digital image mosaics of many high-resolution digital photographs or using a film negative as large as 12" × 9" (30 cm × 23 cm) up to 18" × 9" (46 cm × 23 cm), which is then scanned with a high-end large-format film scanner with at least 3000 dpi resolution. A square image of 31,623 pixels in width and height is one gigapixel. A gigapixel rendering of a 2D fractal (~2.15 gigapixels).Ī gigapixel image is a digital image bitmap composed of one billion (10 9) pixels (picture elements), 1000 times the information captured by a 1 megapixel digital camera.
