Måling

Målingen betegner den måde, hvorpå kameraet måler mængden af lys til indstilling af eksponeringen.

MJPEG (Motion JPEG)

Et videoformat der er komprimeret som et JPEG-billede.

Støj

"Misfortolkede" pixels i et digitalt billede der anbringes forkert eller tilfældige, lysende pixels. Støj opstår normalt, når et billede optages med en høj følsomhed, eller når følsomheden indstilles automatisk på mørke steder.

Optisk zoom

Dette er en generel zoom, der kan forstørre billeder med et objektiv, og som ikke forringer billedkvaliteten.

Kvalitet

Et udtryk for den grad af komprimering, der anvendes på et digitalt billede. Billeder med højere kvalitet har en lavere komprimeringsgrad, og det medfører oftest en større filstørrelse.

Opløsning

Det antal pixels der findes i et digitalt billede. Billeder med høj opløsning indeholder flere pixels og viser typisk flere detaljer end billeder med lav opløsning.

Lukkerhastighed

Lukkerhastigheden refererer til den tid, det tager at åbne og lukke lukkeren, og dette er en vigtig faktor for et billedes lysstyrke, da den kontrollerer den mængde lys, der når at komme ind gennem blænderen, før det når billedsensoren. En høj lukkerhastighed vil give mindre tid til at lukke lyset ind, hvorfor billedet vil blive mørkere, og du kan lettere tage billeder af motiver i bevægelse.

Vignettering

En reduktion af et billedes lysstyrke eller mætning i periferien (ydre kanter) sammenlignet med billedets midte. Vignettering kan henlede opmærksomheden på genstanden der er anbragt i midten af et billede.

Hvidbalance (farvebalance)

En justering af farvernes intensitet (typisk primærfarverne rød, grøn og blå) i et billede. Målet med justering af hvidbalancen - eller farvebalancen - er at gengive farverne i et billede korrekt.
