(* The pixel number of 6,000x4,000 ist the number of "effective pixels". The sensor usually has a few extra rows of pixels on all four sides, which explains the sensor resolution of 24.3 MPixels often stated, but no information about the exact image size available.) 6,016 4,000 24,064,000 24.1 Nikon D3300 Canon M50: 6,048 4,032 24,385,536 24.4
Scanners differ significantly from digital camera in many areas. First, the optical resolution of a flatbed scanner can exceed 5000 pixels per inch (200 pixels per mm). Even at a relatively low resolution of 1200 pixels per inch (47 p/mm) a letter sized image would be 134 megapixels in size.
The spatial resolution of consumer displays ranges from 50 to 800 pixel lines per inch. With scanners, ... Analogue and early digital [3] Many cameras and displays ...
In digital photography, pixel density is the number of pixels divided by the area of the sensor. A typical DSLR , circa 2013, has 1–6.2 MP/cm 2 ; a typical compact has 20–70 MP/cm 2 . For example, Sony Alpha SLT-A58 has 20.1 megapixels on an APS-C sensor having 6.2 MP/cm 2 since a compact camera like Sony Cyber-shot DSC-HX50V has 20.4 ...
Because of the relatively large size of the imaging area these media provide, they can record higher resolution images than most consumer digital cameras. Based upon the above pixel density, a medium-format film image can record an equivalent resolution of approximately 83 million pixels in the case of a 60 x 60 mm frame, to 125 million pixels ...
A planetary scanner is a type of very-high-resolution document camera used for capturing certain fragile documents. [57] A book scanner is another kind of document camera, pairing a digital camera with a scanning area defined by a mat to assist in scanning books. Some more advanced models of book scanners project a laser onto the page for ...
The first scan done by the SEAC in 1957 The SEAC scanner. Early digital fax machines such as the Bartlane cable picture transmission system preceded digital cameras and computers by decades. The first picture to be scanned, stored, and recreated in digital pixels was displayed on the Standards Eastern Automatic Computer at NIST. [12]
The camera weighed 8 pounds (3.6 kg), recorded black-and-white images to a cassette tape, had a resolution of 0.01 megapixels (10,000 pixels), and took 23 seconds to capture its first image in December 1975.
