    Screenshot of Windows 8's Settings app. Screenshot of Windows 8.1's Settings app. The first generation of the app, called "PC Settings" was included with Windows 8, Windows Server 2012, Windows 8.1, and Windows Server 2012 R2. On Windows 8, the PC Settings app was designed as a simplified area optimized for use on touchscreen devices.

  3. Digital camera modes - Wikipedia

    en.wikipedia.org/wiki/Digital_camera_modes

    Macro or close-up modes tend to direct the camera's focus to be nearer the camera. They may shrink the aperture and restrict the camera to wide-angle in an attempt to broaden the depth-of-field (to include closer objects) – this last mode of operation is often known as Super Macro. Movie mode allows a still camera to take moving pictures.

  4. Gamma correction - Wikipedia

    en.wikipedia.org/wiki/Gamma_correction

    For a CRT, the gamma that relates brightness to voltage is usually in the range 2.35 to 2.55; video look-up tables in computers usually adjust the system gamma to the range 1.8 to 2.2, [1] which is in the region that makes a uniform encoding difference give approximately uniform perceptual brightness difference, as illustrated in the diagram at ...

  5. Color balance - Wikipedia

    en.wikipedia.org/wiki/Color_balance

    The left half shows the photo as it came from the digital camera. The right half shows the photo adjusted to make a gray surface neutral in the same light. In photography and image processing, color balance is the global adjustment of the intensities of the colors (typically red, green, and blue primary colors). An important goal of this ...

  6. Automatic gain control - Wikipedia

    en.wikipedia.org/wiki/Automatic_gain_control

    Schematic of an AGC used in the analog telephone network; the feedback from output level to gain is effected via a Vactrol resistive opto-isolator.. Automatic gain control (AGC) is a closed-loop feedback regulating circuit in an amplifier or chain of amplifiers, the purpose of which is to maintain a suitable signal amplitude at its output, despite variation of the signal amplitude at the input.

  7. Chroma subsampling - Wikipedia

    en.wikipedia.org/wiki/Chroma_subsampling

    [clarification needed] This knowledge allowed RCA to develop a system in which they discarded most of the blue signal after it comes from the camera, keeping most of the green and only some of the red; this is chroma subsampling in the YIQ color space and is roughly analogous to 4:2:1 subsampling, in that it has decreasing resolution for luma ...

  8. PlayStation Eye - Wikipedia

    en.wikipedia.org/wiki/PlayStation_Eye

    The camera features a two-setting adjustable fixed-focus zoom lens. Selected manually by rotating the lens barrel, the PlayStation Eye can be set to a 56 ° field of view (red dot) similar to that of the EyeToy, [ 11 ] for close-up framing in chat applications, or a 75° field of view (blue dot) for long-shot framing in interactive physical ...

  9. Black level - Wikipedia

    en.wikipedia.org/wiki/Black_level

    Video black level is defined as the level of brightness at the darkest (black) part of a visual image or the level of brightness at which no light is emitted from a screen, resulting in a pure black screen. Video displays generally need to be calibrated so that the displayed black is true to the black information in the video signal. If the ...
