What is gamma vs luma?
Luma refers to the luminance or rather the percentage of black to white in a color image. Gamma refers to the luminance as seen on a television or computer monitor. Chroma refers the range of colors after the red, blue and green elements have been mixed.
What color space uses luma?
YUV color space was particularly useful when color was first introduced to television as it could decode and display both color and black and white. Like all color spaces, YUV is just an abbreviated term for 'luma', 'red projection' and 'blue projection'.
What is the difference between luma and lightness?
Gamma correction: The process of coding and decoding luminance with the aim of optimizing the output for human vision. Luma: Used primarily in video, luma is the weighted sum of gamma-corrected RGB values. Lightness: A subjective measure of brightness, relative to the brightness of a white point.
What are luma and chroma components?
Video signals would be separated into a lightness or "luma" component and two color or "chroma" components, similar to how images can be separated into three red, green and blue (RGB) components. The luma and chroma components would then be referred to as YUV (with analog) or YCbCr (with digital) as opposed to RGB.
