    en.wikipedia.org/wiki/Enhanced-definition_television

    To achieve EDTV, consumer electronic devices such as a progressive scan DVD player or modern video game consoles must be connected through at least a component video cable (typically using 3 RCA cables for video), a VGA connector, or a DVI or HDMI connector. For over-the-air television broadcasts, EDTV content uses the same connectors as HDTV.

    Samsung NX500 - Same 28 MP APS-C sensor as NXI but 4K video is not downsampled from 6.5K so less details and more noise than the NX1 - with this 2.4× crop factor the kit lens become a 38–120mm f8.5–13.4 equivalent for depth of field; 15 min max recording time limit

  4. Motion picture film scanner - Wikipedia

    en.wikipedia.org/wiki/Motion_picture_film_scanner

    The scanner scans the film frames into a file sequence (using high-end computer data storage devices), whose single file contains a digital scan of each still frame; the preferred image file format used as output are usually Cineon, DPX or TIFF, because they can store color information as raw data, preserving the optical characteristics of the ...

    Printing on paper is accomplished with different technologies. Newspapers and magazines were traditionally printed using a halftone screen, [ 2 ] which would print dots at a given frequency, the screen frequency, in lines per inch (LPI) by using a purely analog process in which a photographic print is converted into variable sized dots through ...

    Screen-door effects are more noticeable than LCD when up close, or on larger sizes. [53] New models are no longer produced. Colored sub-pixels may age at different rates, leading to a color shift, although some models will scan pixels to even out wear and prevent this shift. [54] Sensitive to UV light from direct sunlight.

  7. Scan line - Wikipedia

    en.wikipedia.org/wiki/Scan_line

    Scan lines are important in representations of image data, because many image file formats have special rules for data at the end of a scan line. For example, there may be a rule that each scan line starts on a particular boundary (such as a byte or word; see for example BMP file format). This means that even otherwise compatible raster data ...

  8. Progressive scan - Wikipedia

    en.wikipedia.org/wiki/Progressive_scan

    Prices for consumer-grade 4K HDTVs have since lowered and become more affordable, which has increased their prevalence amongst consumers. Computer monitors can use even greater display resolutions. The disadvantage of progressive scan is that it requires higher bandwidth than interlaced video that has the same frame size and vertical refresh ...

  9. Screen printing - Wikipedia

    en.wikipedia.org/wiki/Screen_printing

    Screen printing is a printing technique where a mesh is used to transfer ink (or dye) onto a substrate, except in areas made impermeable to the ink by a blocking stencil.A blade or squeegee is moved across the screen in a "flood stroke" to fill the open mesh apertures with ink, and a reverse stroke then causes the screen to touch the substrate momentarily along a line of contact.
