Method to distinguish details better in the dark areas of a picture.
Before being displayed, the linear RGB data must be processed (gamma corrected) to compensate for the gamma of the display.
This is a method to correct the lightness or darkness of pictures, so that the pictures appear with the same brightness on any monitor.
In a linear color space, color levels are equally spaced throughout a gamut. The problem with this type of color space is that level-to-level changes at the low end of the gamut seem greater to the eye than equal changes at the high end. In a gamma-corrected color space, color levels are spaced logarithmically so that level-to-level changes seem consistent throughout the range.
A built in camera feature that adjusts for the brightness characteristic of the monitor
Refers to the correction of linear response of a video camera image sensor in order to compensate for the monitor phosphor screen nonlinear response. Without gamma correction set to the inverse (exact opposite corresponding value) of the monitor's gamma, a video camera would not be able to provide a complete video image for a unified display. Gamma correction is measured with the exponential value of the curve describing the non-linearity.
As not all screens or printers are the same, colors have to be adjusted from the computers idea of "normal" before they are displayed.
a non-linear adjustment of the pixel values to compensate for this difference and produce a more accurate representation on the screen
A function applied to colors stored in the framebuffer to correct for the nonlinear response of the eye (and sometimes of the monitor) to linear changes in color-intensity values.
A method of correcting the lightness or darkness of pictures, so that they appear with the same brightness on any monitor.
Gamma correction is a form of brightness editing which has a lesser impact on the overall look of a picture than normal brightness adjustment. Only the parts of the picture which are neither too light nor too dark are adjusted.
In reference to displaying an image accurately on a computer screen, Gamma correction controls the overall brightness of an image. Images which are not properly corrected can look either bleached out, or too dark.
An electronic correction carried out by the camera circuitry to balance the brightness seen by the camera to that of the monitor.
Adjustment of the intensity values of an image (loosely speaking, a combination of brightness and contrast) in order to compensate for variations in output devices. For example, images displayed on a standard Macintosh must be gamma-corrected to appear the same way they do on a standard PC, and vice versa.
A method for controlling how midtones are rendered in a scanned image.
The changing of the brightness, contrast or color balance by assigning new values to the gray or color tones. Gamma correction can be either linear or nonlinear. Linear changes effect all tones, nonlinear changes effect only areas tone by tone, like highlights, shadows, or midtones.
A CCU control which can alter the progression of the black-to-white tonal range. Often used to open up shadow areas in a low-key picture or to hold picture detail in bright video areas.
The process of altering the gamma of computer graphics, pictures, or video in order to make the picture show up properly and enable the proper recognition...
The tone value characteristic for all monitors can be adjusted by means of the gamma correction value. The color reproduction of ColorEdge monitors is controlled by an internal 10-bit Look-Up-Table (LUT). It facilitates a more exact gradation of color information than a standard 8-bit LUT. By means of integrated color management, color saturation and color intensity can be also separately adjusted for RGB and CMY.
A form of tone mapping in which the shape of the tone map is a gamma.
The correction of tonal ranges in an image, normally by the adjustment of tone curves.
Correction of gray-scale inconsistency. The brightness characteristic of a CRT is not linear with respect to voltage; the voltage-to-intensity characteristic is usually close to a power of 2.2. If left uncorrected, the resulting display has too much contrast and detail in black regions is not reproduced. To correct this inconsistency, a correction factor using the 2.2 root of the input signal is included, so that equal steps of brightness or intensity at the input are reproduced with equal steps of intensity at the display.
A computer monitor displays colors by exciting phosphors on the screen. Unfortunately, phosphors do not excite linearly. For example, if a computer reads a luminance value from a photographic image and sends it directly to the monitor, the displayed color will be dimmer than in the original photograph. The gamma correction adjusts for the nonlinearity of phosphor excitation. (The gamma is the numeric power to which the video signal voltage is raised to obtain a linear light response).
Adjusts the video display image to correspond with that seen by the video camera or video input when the gamma is non-linear.
Th is is a process that makes pictures appear more accurately on a specific monitor via tone mapping.
Non-linear tonal correction that edits an image's gamma curve.
To provide for a linear transfer characteristic from input to output device.
A nonlinear correction factor which is supposed to convert an evenly-spaced grayscale palette to evenly-spaced levels of brightness in the monitor (as measured by a photometer). It is usually in the form of a table representing the function where gamma is usually 1.7-2.2.
The measure of contrast that results in lightening or darkening the midtone regions of an image. Also, the amount of midtones need to be adjusted on a monitor.
In film and video production, a method of adjusting pixel values so they can be represented properly on an output device. Gamma correction lets you compensate for lack of contrast in a video display.
Gamma correction, gamma nonlinearity, gamma encoding, or often simply gamma, is the name of a nonlinear operation used to code and decode luminance or tristimulus values in video or still image systems.
