A film scanner, also known as a slide scanner or a transparency scanner, is a type of specialized flatbed scanner specifically for scanning film negatives and slides. A typical film scanner works by passing a narrowly focused beam of light through the film and reading the intensity and color of the light that emerges. [ 34 ]
The OneScanner was a series of flatbed scanners marketed by Apple Computer during the early 1990s. The original OneScanner model was introduced in 1991 to replace the earlier Apple Scanner, offering 8-bit (256 shades) greyscale scanning. [1] It was joined by the Color OneScanner the next year, [2] and a series of updated models followed. The ...
"Self portrait with scanner" shows the effects of the focused lighting and limited depth of field when using a scanner to capture a 3-D object. 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).
A flying-spot scanner (FSS) uses a scanning source of a spot of light, such as a high-resolution, high-light-output, low-persistence cathode ray tube (CRT), to scan an image. Usually the image to be scanned is on photographic film, such as motion picture film, or a slide or photographic plate. The output of the scanner is usually a television ...
A film scanner scans original film stock: negative or positive print or reversal/IP. Units may scan gauges from 8 mm to 70 mm (8 mm, Super 8, 9.5 mm, 16 mm, Super 16, 35 mm, Super 35, 65 mm and 70 mm) with very high resolution scanning at 2K, 4K, 8K, or 16K resolutions. (2K is approximately 2048×1080 pixels and 4K is approximately 4096×2160 ...
A push broom scanner, also known as an along-track scanner, is a device for obtaining images with spectroscopic sensors. The scanners are regularly used for passive remote sensing from space, and in spectral analysis on production lines, for example with near-infrared spectroscopy used to identify contaminated food and feed.
