- Gigapixel image
A gigapixel image is a
digital image bitmap composed of one billion (109)pixels (picture elements), more than 150 times the information captured by a mid-range (6megapixel )digital camera . Current technology for creating such veryhigh-resolution images involves makingmosaic s of a large number of high-resolution digital photographs, or uses afilm negative as large as 9"×12" (23 cm×30 cm), which is then scanned with a high-endfilm scanner . Recent developmentsFact|date=May 2007 have demonstrated the practicality of developing scanning cameras capable of creating a gigapixel image in a single sweep of a scene.Gigapixel images are of particular interest to the following:Fact|date=May 2007
* Physicists viewing the results ofsupercomputer simulation s
* Viewers ofsatellite composite image s for various purposes, includingagricultural policy ,land use planning , andmilitary intelligence
* Artists
* Health care providers, such as pathologists, for virtualmicroscopy utilizing whole slide images (digitally scanned glassmicroscope slide s)
* Visual effects industry, where gigapixel images can enable the creation of immersive digital environmentsSee also
