What is chrominance?
Chrominance is part of a video signal that carries information about the attributes of the displayed colors. The development of information about the transmission of information on color paved the way to the color of television, a move that revolutionized the television industry. Colors are given in the form of quantitative measurements compared to standard reference color, so the signal is standardized, although the screen properties can change the way the color expresses. People can use the term "chroma" to indicate chrominance.
The two different features are expressed in the color part of the video signal, shade and saturation, with the color defined by red, green, blue (RGB) with a metric of color for quantitative description of the color. This information is also associated with a lum about brightness. Because the human eye is very sensitive to the differentiation of brightness, chroma and luma can be balanced against each other to achieve a standing, clear image with recognizable color patterns. In this case, the color signal lags slightly behind the brightness signal and as a resultThe colors may look blurry or cold, especially around the lines. This can be very disturbing for some viewers, because even if the delay is not easily visible, it can deceive or confuse your eyes.
When problems are identified with a color part of the broadcast, this may be caused by broadcasting, the problem with the device or the problems of image processing. TV networks generally try to solve the quality of broadcasting quality as quickly as possible to prevent the loss of frustrated viewers who turn off the TV when signal problems persist.
This term is sometimes used among photographers in describing image processing. All cameras generate different stages of "noise" in the pictures they take, and image processing often includes cleaning images to look sharper and more visually pleasant. Because people are more sensitive to brightness changes than in color, they must be worked outCreating for noise chromination carefully to avoid endangering the finished image. Digital image processing programs will divide the image into Chroma and Luma components, allowing people to clean the chromination without sacrificing luma simultaneously, keeping the image fresh with clear contrast, especially in the rear of the picture.
