A gigapixel image is a
digital image
A digital image is an image composed of picture elements, also known as ''pixels'', each with ''finite'', '' discrete quantities'' of numeric representation for its intensity or gray level that is an output from its two-dimensional functions ...
bitmap composed of one

pixels (picture elements), 1000 times the information captured by a 1
megapixel digital camera. A square image of 31,623 pixels in width and height is one gigapixel. 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. 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.

Fulldome projection system, a composite of medical images by Aperio, and Google Earth's Landsat images viewable as a time-lapse are collectively considered over one terapixel.
In 2015 the 'Terabite', the world's first terapixel macro image, was released by GIGAmacro.
