Exempel på hur man kan använda LUMA i en mening

• S-Video can mitigate some of these potential issues, as its luma is transmitted separately from chroma.
• SECAM TV uses FM for the chrominance signal, hence ghosting only affects the luma portion of its signal.
• It also has a backward-compatible trick for sending still images with 704×576 luma resolution and 352×288 chroma resolution (which was added in a later revision in 1993).
• PAL video is composite video because luminance (luma, monochrome image) and chrominance (chroma, colour applied to the monochrome image) are transmitted together as one signal.
• The prime symbol (') denotes that the luma is calculated from gamma-corrected RGB input and that it is different from true luminance.
• Chrominance (chroma or C for short) is the signal used in video systems to convey the color information of the picture (see YUV color model), separately from the accompanying luma signal (or Y' for short).
• With the usual additions of sound carrier and vestigial sideband the result was a combined signal that demanded approximately two to three times the bandwidth of more moderately specified standards, even when colour was added to them (as the color subcarrier resides within the luma signal space).
• SECAM video is composite video; the luminance (luma, monochrome image) and chrominance (chroma, color applied to the monochrome image) are transmitted together as one signal.
• However, the DTV2/PAL version suffers from a manufacturing fault, which results in poor colour rendering (the resistors in the R-2R ladder DACs for both the chroma and the luma have been transposed).
• Chroma subsampling is the practice of encoding images by implementing less resolution for chroma information than for luma information, taking advantage of the human visual system's lower acuity for color differences than for luminance.
• It encodes video luma and chrominance on two separate channels, achieving higher image quality than composite video which encodes all video information on one channel.
