  2. Dots per inch - Wikipedia

    en.wikipedia.org/wiki/Dots_per_inch

    Dots per inch. A close-up of the dots produced by an inkjet printer at draft quality. Actual size is approximately 1⁄4 by 1⁄4 inch (6 by 6 mm). Individual coloured droplets of ink are visible; this sample is about 150 DPI. Dots per inch ( DPI, or dpi [1]) is a measure of spatial printing, video or image scanner dot density, in particular ...

  3. Comparison of digital and film photography - Wikipedia

    However, even if both techniques have inherent noise, it is widely appreciated that for color, digital photography has much less noise/grain than film at equivalent sensitivity, leading to an edge in image quality. [10] For black-and-white photography, grain takes a more positive role in image quality, and such comparisons are less valid.

  4. 6K resolution - Wikipedia

    en.wikipedia.org/wiki/6K_resolution

    6K resolution is mainly used for digital cinema and professional video production, as it offers more detail and clarity than lower resolutions. Some cameras, such as the RED WEAPON 6K Camera, can capture video in 6K resolution. However, there are not many displays that can show 6K resolution natively, as they are very expensive and rare.

  5. Digital cinematography - Wikipedia

    en.wikipedia.org/wiki/Digital_cinematography

    Digital cinematography is the process of capturing (recording) a motion picture using digital image sensors rather than through film stock. As digital technology has improved in recent years, this practice has become dominant. Since the mid-2010s, most movies across the world are captured as well as distributed digitally.

  6. List of common display resolutions - Wikipedia

    The extra pixels are used to form the increased area to the sides of the D1 image. The pixel density of 960H is identical to standard D1 resolution so it does not give any improvement in image quality, merely a wider aspect ratio. Alternative analog video transport technologies carrying higher resolutions than 960H include HD-TVI, HDCVI, and AHD.

  7. Pixel density - Wikipedia

    en.wikipedia.org/wiki/Pixel_density

    Scanners and cameras. "PPI" or "pixel density" may also describe image scanner resolution. In this context, PPI is synonymous with samples per inch. 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 .

  8. Digital video - Wikipedia

    en.wikipedia.org/wiki/Digital_video

    Digital video comprises a series of digital images displayed in rapid succession. In the context of video, these images are called frames. [e] The rate at which frames are displayed is known as the frame rate and is measured in frames per second. Every frame is a digital image and so comprises a formation of pixels.

  9. Moving image formats - Wikipedia

    en.wikipedia.org/wiki/Moving_image_formats

    The best quality for 50 Hz material is provided by digital motion analysis. Modern digital systems. Digital video is free of many of the limitations of analog transmission formats and presentation mechanisms (e.g. CRT display) because it decouples the behavior of the capture process from the presentation process. As a result, digital video ...
