  2. Contrast ratio - Wikipedia

    en.wikipedia.org/wiki/Contrast_ratio

    An LCD technology is dynamic contrast (DC), also called advanced contrast ratio (ACR), and smart contrast ratio (SCR [4]) and various other designations.When there is a need to display a dark image, a display that supports dynamic contrast underpowers the backlight lamp (or decreases the aperture of the projector's lens using an iris), but proportionately amplifies the transmission through the ...

  3. Contrast resolution - Wikipedia

    en.wikipedia.org/wiki/Contrast_resolution

    Contrast resolution or contrast-detail is an approach to describing the image quality in terms of both the image contrast and resolution. Contrast resolution is usually measured by generating a pattern from a test object that depicts how image contrast changes as the structures being imaged get smaller and closer together.

  4. Contrast (vision) - Wikipedia

    en.wikipedia.org/wiki/Contrast_(vision)

    The maximum contrast of an image is termed the contrast ratio or dynamic range. In images where the contrast ratio approaches the maximum possible for the medium, there is a conservation of contrast. In such cases, increasing contrast in certain parts of the image will necessarily result in a decrease in contrast elsewhere.

  5. Display contrast - Wikipedia

    en.wikipedia.org/wiki/Display_contrast

    The "luminance contrast" is the ratio between the higher luminance, L H, and the lower luminance, L L, that define the feature to be detected.This ratio, often called contrast ratio, CR, (actually being a luminance ratio), is often used for high luminances and for specification of the contrast of electronic visual display devices.

  6. Gamma correction - Wikipedia

    en.wikipedia.org/wiki/Gamma_correction

    Graphics card and monitor contrast and brightness have an influence on effective gamma, and should not be changed after gamma correction is completed. The top two bars of the test image help to set correct contrast and brightness values. There are eight three-digit numbers in each bar.

    NOTE: Some browsers alter the gamma of a displayed image, so to see the actual, unmodified image and get a more exact result, it should be downloaded and viewed using photo software. Deutsch: Ein Testbild, um Ihren Monitor auf die Darstellung fotografischer Schattendetails zu überprüfen.

  9. Histogram equalization - Wikipedia

    en.wikipedia.org/wiki/Histogram_equalization

    This method usually increases the global contrast of many images, especially when the image is represented by a narrow range of intensity values. Through this adjustment, the intensities can be better distributed on the histogram utilizing the full range of intensities evenly. This allows for areas of lower local contrast to gain a higher contrast.
