Color targets such as the ColorChecker can be captured by cameras and other color input devices, and the resulting images’ output can be compared to the original chart, or to reference measurements, to test the degree to which image acquisition reproduction systems and processes approximate the human visual systems.
Greenshot offers several modes for creating a screenshot: "Capture region" allows to select an area of the screen by dragging a green rectangle to the desired position and size. "Capture last region" is used to re-capture exactly the same area that was captured before.
Launched by Google in February 2013, the Chromebook Pixel was the high-end machine in the Chromebook family. The laptop has an unusual 3:2 display aspect ratio touch screen featuring what was at its debut the highest pixel density of any laptop, [131] a faster CPU than its predecessors in the Intel Core i5, and an exterior design described by ...
Screen capture may refer to: Screenshot , an image file which shows the content of a computer's screen at the moment of shot Screencast , also known as a video screen capture , a digital recording of computer screen output, often containing audio narration
Luma is the weighted sum of gamma-compressed R′G′B′ components of a color video—the prime symbols ′ denote gamma compression. The word was proposed to prevent confusion between luma as implemented in video engineering and relative luminance as used in color science (i.e. as defined by CIE ).
A screencast is a digital recording of computer screen output, also known as a video screen capture or a screen recording, often containing audio narration. [1] The term screencast compares with the related term screenshot; whereas screenshot generates a single picture of a computer screen, a screencast is essentially a movie of the changes over time that a user sees on a computer screen, that ...
This chart shows the most common display resolutions, with the color of each resolution type indicating the display ratio (e.g., red indicates a 4:3 ratio). This article lists computer monitor, television, digital film, and other graphics display resolutions that are in common use. Most of them use certain preferred numbers.
Color constancy is, in turn, related to chromatic adaptation. Conceptually, color balancing consists of two steps: first, determining the illuminant under which an image was captured; and second, scaling the components (e.g., R, G, and B) of the image or otherwise transforming the components so they conform to the viewing illuminant.
