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. 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. A gigamacro image is a gigapixel image which is a close-up or macro image. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Photographic Techniques
Photography is the art, application, and practice of creating durable images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive, depending on the purpose ...

Digital Photography
Digital photography uses cameras containing arrays of electronic photodetectors interfaced to an analog-to-digital converter (ADC) to produce images focused by a lens, as opposed to an exposure on photographic film. The digitized image is stored as a computer file ready for further digital processing, viewing, electronic publishing, or digital printing. Digital photography spans a wide range of applications with a long history. In the space industry, where much of the technology originated, it pertains to highly customized, embedded systems combined with sophisticated remote telemetry. Any electronic image sensor can be digitized; this was achieved in 1951. The modern era in digital photography is dominated by the semiconductor industry, which evolved later. An early semiconductor milestone was the advent of the charge-coupled device (CCD) image sensor, first demonstrated in April 1970; the field has advanced rapidly and continuously ever since, paced by concurrent advances ...

VR Photography
VR photography (after virtual-reality photography) is the interactive viewing of panoramic photographs, generally encompassing a 360-degree circle or a spherical view. The results is known as VR photograph (or VR photo), 360-degree photo, photo sphere, or spherical photo, as well as interactive panorama or immersive panorama. VR photography is the art of capturing or creating a complete scene as a single image, as viewed when rotating about a single central position. Normally created by stitching together a number of photographs taken in a multi-row 360-degree rotation or using an omnidirectional camera, the complete virtual reality image can also be a totally computer-generated effect, or a composite of photography and computer generated objects. The history of VR photography is human-computer interaction in which a real or imaginary environment is simulated and users interact with and manipulate that world. Capture There are several ways of capturing VR photography. Rectili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gigapan
GigaPan Systems is a global, privately held technology company that provides hardware, software, and services to create and share high-resolution, interactive gigapixel panoramic images. The company is headquartered in Portland, Oregon. History GigaPan Systems was founded in 2008 as a collaborative project between Carnegie Mellon University and NASA’s Ames Research Center with support from Google. The original GigaPan robotic hardware and related software were devised for NASA's Mars Spirit and Opportunity Rovers, to capture high-definition panoramas of Mars. The development team was led by Randy Sargent, a senior systems scientist at Carnegie Mellon West and the NASA Ames Research Center in Moffett Field, Calif., and Illah Nourbakhsh, associate professor of robotics at Carnegie Mellon in Pittsburgh. The project has since grown into an independent company offering solutions for capturing gigapixel images. Technology GigaPan Systems combines high-definition images and panoramas ...

Powerwall
A powerwall is a large, ultra-high-resolution display that is constructed of a matrix of other displays, which may be either monitors or projectors. It is important to differentiate between powerwalls and displays that are just large, for example, the single projector display used in many lecture theatres. These displays rarely have a resolution higher than pixels, and so present the same amount of information as on a standard desktop display. With Powerwall displays, users can view the display from a distance and see an overview of the data (context), but can also move to within arm’s length and see data in great detail (focus). This technique of moving around the display is known as physical navigation, and can help users to better understand their data. The first Powerwall display was installed at the University of Minnesota in 1994. It was made of four rear-projection displays, providing a resolution of 7.8 million pixels ( pixels). Increases in graphic display power, co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Largest Photographs In The World
Negative The largest seamless photograph made in a single exposure was made using a Southern California jet hangar transformed into a giant camera. The most recent claim to the largest image stitched together was by the Canadian Museum of Civilization. On 3 August 2015, the ''longest'' photographic negative was measured wide. This negative was created bEsteban Pastorino Díaz(Spain) by driving on the 2nd Ring Road (Beijing). Esteban Pastorino Díaz also holds the previous record, a negative measured wide. He used a custom-built panoramic slit camera on 13 June 2010. The negative is a panorama of major streets in Buenos Aires, Argentina, captured by the slit camera while mounted on the roof of a moving car. Largest seamless example *Name of project/picture: '' The Great Picture'' *Claimed by: The Legacy Project; (Jerry Burchfield, Mark Chamberlain, Jacques Garnier, Rob Johnson, Douglas McCulloh, and Clayton Spada) *Photograph of: control tower and runways at the U.S. Marine ...
