Infrared Cleaning
Infrared cleaning is a technique used by some film scanners and flatbed scanners to reduce or remove the effect of dust and scratches upon the finished scan. It works by collecting an additional infrared channel from the scan at the same position and resolution as the three visible color channels (red, green, and blue). The infrared channel, in combination with the other channels, is used to detect the location of scratches and dust. Once located, those defects can be corrected by scaling or replaced by inpainting. Method The three color dyes in typical color film emulsions are largely transparent to infrared light, so the infrared image is almost uniformly clear, unlike the RGB images. On the other hand, dust absorbs and scratches scatter the infrared. Any dust spots or scratches appear as dark marks in the infrared, making them easy to find and compensate for. Pixels that are partially occluded (for example, the dust only obscures a small portion of the pixel) may be corrected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SilverFast
SilverFast is the name of a family of software for image scanning and processing, including photos, documents and slides, developed by LaserSoft Imaging. There are also other applications for image processing using digital cameras or printers and for 48-bit raw data image processing. History SilverFast was introduced in 1995, it is still under development today. Some scanner manufacturers bundle their hardware with SilverFast software. Some of the features developed for SilverFast, especially in the area of color management, error detection and automatic dust and scratch removal, have been patented. The European Digital Press Association named SilverFast the "Best colour management software of the year 2008" for improving the dynamic range of most scanners and for creating ICC profiles automatically. In 2011 version 8 was introduced, and HDR imaging software followed in 2012. SilverFast 9 has been released in 2020. Patents * 2005: Patent granted on barcode technology used ...

Film Scanner
A film scanner is a device made for scanning photographic film directly into a computer without the use of any intermediate printmaking. It provides several benefits over using a flatbed scanner to scan in a print of any size: the photographer has direct control over cropping and aspect ratio from the original, unmolested image on film; and many film scanners have special software or hardware that removes scratches and film grain and improves color reproduction from film. Film scanners can accept either strips of 35 mm or 120 film, or individual slides. Low-end scanners typically only take 35mm film strips, while medium- and high-end film scanners often have interchangeable film loaders. This allows the one scanning platform to be used for different sizes and packaging. For example, some allow microscope slides to be loaded for scanning, while mechanised slide loaders allow many individual slides to be batch scanned unattended. Some software used to process images scanned ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

LaserSoft Imaging
LaserSoft Imaging AG is a software developer designing software such as SilverFast for scanners and large format printers. The company's headquarters are located in Kiel, Germany, north of Hamburg, and another office in Sarasota, Florida, United States. History 1986 - 1990 LaserSoft Imaging was founded in Spring 1986 by the physicist Karl-Heinz Zahorsky, the president of the company today. LaserSoft Imaging became an early adopter of color- and image processing on the Macintosh. It was the first company to distribute video digitizers, such as Pixelogic's 'ProViz' and Truvel's 'TrueScan', the first professional color scanner for the Macintosh, which was first shown at Hannover trade fair CeBIT in 1988, to which LaserSoft Imaging was invited by Apple Computer. 1990 - 2000 Karl-Heinz Zahorsky published many articles about image processing in several professional journals. In 1990 Hell Graphics, the world's leading drum scanner developer in Kiel, hired him as an indepen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hamrick Software
VueScan is a computer program for image scanning, especially of photographs, including negatives. It supports optical character recognition (OCR) of text documents. The software can be downloaded and used free of charge, but adds a watermark on scans until a license is purchased. Purpose VueScan is intended to work with a large number of image scanners, excluding specialised professional scanners such as drum scanners, on many computer operating systems (OS), even if drivers for the scanner are not available for the OS. These scanners are supplied with device drivers and software to operate them, included in their price. A 2014 review considered that the reasons to purchase VueScan are to allow older scanners not supported by drivers for newer operating systems to be used in more up-to-date systems and for better scanning and processing of photographs (prints; also slides and negatives when supported by scanners) than is afforded by manufacturers' software.

Digital ICE
{{Short description, Technique used to automatically remove dust and scratches from scanned film stock Digital ICE or Digital Image Correction and Enhancement is a set of technologies related to producing an altered image in a variety of frequency spectra. The objective of these technologies is to render an image more usable by Fourier or other filtering techniques. These technologies were most actively advanced in the 1960s and early 1970s in the fields of strategic reconnaissance and medical electronics. The term ''Digital ICE'' initially applied specifically to a proprietary technology developed by Kodak's Austin Development Center, formerly Applied Science Fiction (ASF), that automatically removes surface defects, such as dust and scratches, from scanned images. Technology The ICE technology works from within the scanner, so unlike the software-only solutions it does not alter any underlying details of the image.

Minolta
was a Japanese manufacturer of cameras, camera accessories, photocopiers, fax machines, and laser printers. Minolta Co., Ltd., which is also known simply as Minolta, was founded in Osaka, Japan, in 1928 as . It made the first integrated autofocus 35 mm SLR camera system. In 1931, the company adopted its final name, an acronym for "Mechanism, Instruments, Optics, and Lenses by Tashima". In 2003, Minolta merged with Konica to form Konica Minolta. On 19 January 2006, Konica Minolta announced that it was leaving the camera and photo business, and that it would sell a portion of its SLR camera business to Sony as part of its move to pull completely out of the business of selling cameras and photographic film.

Kodachrome
Kodachrome is the brand name for a color reversal film introduced by Eastman Kodak in 1935. It was one of the first successful color materials and was used for both cinematography and still photography. For many years Kodachrome was widely used for professional color photography, especially for images intended for publication in print media. Because of its complex processing requirements, the film was initially exclusively sold process-paid in the United States: customers had to pay Kodak for the cost of development when they bought the film, and independent photography stores were prohibited from developing Kodachrome photos. To develop the film, customers had to mail film to Kodak, who mailed the developed photos back for no additional charge. In 1954, the U.S. Department of Justice found this practice to be an uncompetitive violation of antitrust law. Kodak entered into a consent decree requiring they offer Kodachrome film for sale with and without the development fee, as ...
