Gigapixel image

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" × 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. 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]

A gigamacro image is a gigapixel image which is a close-up or macro image.

Gigapixel images may be of particular interest to the following:

Terapixel

A terapixel image is an image composed of one trillion (1012) pixels. Though currently rare, there have been a few instances such as the Microsoft Research Terapixel project for use on the Fulldome projection system,[3] a composite of medical images by Aperio,[4][5] and Google Earth's Landsat images viewable as a time-lapse are collectively considered over one terapixel.[6]

In August, 2014, GIGAmacro announced that they would capture the photographs for the world's first terapixel macro image at the annual SIGGRAPH conference in Vancouver, BC.[7] As of the end of August, 2014 GIGAmacro announced the success of the capture phase of the project, but have not yet said when the final terapixel image will be made public.[8]
