Usage examples
  • Värvsussignaali kujutatakse tavaliselt kahe värvierinevuse komponendina: U = B′ − Y′ (sinine − luma) ja V = R′ − Y′ (punane − luma) ja igale neist erinevatest komponentidest võib olla rakendatud mastaabitegureid ja nihkeid, nagu on täpsustatud kohaldatavas videostandardis.
chrominance signal
Usage examples
  • Chrominance signal is usually represented as two color-difference components: U = B′ − Y′ (blue − luma) and V = R′ − Y′ (red − luma). Each of these different components may have scale factors and offsets applied to it, as specified by the applicable video standard.
