JPEG

King computing, ing JPEG (a yagkas dang JAY-peg; IPA: /ˈdʒeɪpɛɡ/), metung yang maralas gagamitan a paralan ning compression para kareng letratu (photographic images). Maliari yang alilan ing sikan (o pangasiksik) ning pamag-compress, ania maliaring mamili king dagul ning simpan (file size) ampo ing lino ning larawan. Keraklan, babie yang 10 to 1 compression ing JPEG, at ditak mu ing mayayakit a pangabawas king lino ning larawan.

Ing JPEG ing maralas diling magagamit a format para kareng larawan a gagamitan da reng digital camera ampo reng aliwang kasangkapan a kukuang larawan. Iti murin ing pekamaralas dang gagamitan king pamagsimpan (storing) ampong pamagparalang larawan kapamilatan ning World Wide Web.

Ing JPEG standard

Ing lagiung "JPEG" mangabaldugan yang Joint Photographic Experts Group, ing lagiu ning komite o lupung a miglalang ketang standard. Mitátag ya iting grupu aniang 1986, at migpalual yang standard kanitang [[1992[[, at me-apruba ya o metanggap iti kanitang 1994 antimong ISO 10918-1. Aliwa ya ing JPEG king MPEG (Moving Picture Experts Group), a gagawang sistema ning pamag-compress para kareng alben o video.

Tutulduan/lilinawan ne ning JPEG standard ing codec, a mag-isplika nung makananu yang ko-compress o sisiksik ing metung a larawan king agus (stream) da reng byte, at lalako nong pasibayu pangasiksik (decompress) deti ba lang isubli pangabalangkas king metung a larawan, ampo ing file format a magagamit king pamaglangkap o pamanyinup (contain) king agus a ita.
