JPEG yosintha 9.1 imasulidwa ndi chithandizo chopanda malire chopanda malire

Independent JPEG Gulu yalengeza zakusintha kwa mtundu wa JPEG womwe umadzaza ndi kuya kwa mitundu ya 12-bit, kukulitsa kwakukula, komanso kuponderezana koperewera.

Ojambula ambiri odziwa bwino ntchito amawombera mu RAW mtundu wamtunduwu chifukwa zomwe sizinasinthidwe motero sizimataya mawonekedwe. Mafayilo a RAW amasunga zidziwitso zonse mpaka mafayilo amasinthidwa ndi pulogalamu yapadera, monga Lightroom.

RAW ndiye muyezo wazithunzi zapamwamba, koma fayilo yazithunzi imayenda ndi dzina la JPEG, lomwe limaimira Gulu Lophatikiza Ophatikiza Zithunzi. JPG ndi mawu ena ofala amtundu wamtunduwu.

Ngakhale ndiwotchuka kwambiri padziko lonse lapansi, ili ndi cholakwika chimodzi chachikulu: njira yake yoponderezera ndi "yotayika", chifukwa chake imataya chidziwitso chofunikira pakujambula zithunzi monga momwe zimachitikira mkati mwa kamera.

Mwamwayi, mtunduwo wakhala ukulandila zosintha kwa zaka zopitilira 10, ndikukhala bwinoko. Independent JPEG Gulu ndi lomwe limayang'anira mtundu wamafayilo ndipo yangotulutsa kumene mtundu wa 9.1 wa muyezo wa JPEG.

Mtundu wa JPEG 9.1 tsopano ukupezeka kuti utsitsidwe ndi kuzama kwa mtundu wa 12-bit ndikutsitsa koperewera.

JPEG yosintha 9.1 tsopano ikupezeka, imabweretsa kupanikizika kosatayika komanso mitundu 12-bit

Kusinthaku kumaphatikizaponso kusintha komwe kudafunidwa pamachitidwe opanikizika, omwe pano akutaya zambiri zomwe sizingabwezeretsedwe. Komabe, chifukwa cha JPEG update 9.1, muyezo uwu tsopano utha kuthandizira kukakamira kosatayika.

Gawo labwino kwambiri ndikuti JPEG kukhala yopanda malire yopanikizika idzakhala ndi tanthauzo lalikulu pakujambula kwa HDR (High Dynamic Range) ndi ntchito za AR (Augmented Reality).

Laibulale ya "libjpeg" yakhala ikugwiritsidwa ntchito ngati maziko a JPEG kuyambira 1991. Pafupifupi zaka 23 zapita, koma kukakamizidwa kowonjezedwa pamapeto pake kukuyenda bwino polemba masamu.

Chinthu china chofunikira chatsopano chimakhala ndi kuthandizira kwamitundu 12-bit. Fayilo yamtunduwu idzajambula mitundu yambiri yamphamvu, chifukwa chake mawonekedwe owala adzawonjezeredwa kwambiri.

Kuphatikiza apo, ntchito zokulitsa zasinthidwa, nawonso, ndipo tsopano ndi gawo la china chotchedwa Smart Scale.

Kulera mwana kudzatenga kanthawi, choncho musayembekezere kuti zithunzi zanu za JPEG zizikhala bwino tsiku limodzi

Nambala yoseri kwazomwe zaposachedwa kwambiri za JPEG ikupezeka kuti izitsitsidwa pa tsamba lovomerezeka la Institute for Applied Informatics.

Ndikothekera kuti oyamba kutengera izi ndi makampani osindikiza ndikuwonetsa, pomwe opanga makamera a digito atenga kanthawi kuti asinthe ukadaulo wawo wapano wa JPEG pogwiritsa ntchito kulembera kwatsopano.

Pakadali pano, RAW idzakhalabe muyeso wa kuperewera kopanda malire ndikusintha zithunzi, koma ndizosangalatsa kuwona kupita patsogolo kodabwitsa komwe kumapangidwa ndi fayilo ya JPEG ndipo posachedwa titha kugula makamera omwe amatha kuthana ndi kuya kwa utoto wa 12-bit kuchokera pamafayilo a JPEG.
