Kodi Ndiyenera Kugwiritsa Ntchito Kuchepetsa Phokoso la 3D mu Kamera?

Monga momwe tikudziwira, phokoso ndi chinthu chomwe sichingapeweke chifukwa cha ma amplifier omwe ali m'makamera achitetezo. "Phokoso" la kanema ndi mtundu wa "static" womwe umapanga chifunga, ma speckles, ndi fuzz zomwe zimapangitsa chithunzi cha kamera yanu yowunikira kuti chisamveke bwino m'malo opanda kuwala. Kuchepetsa phokoso ndikofunikira kwambiri ngati mukufuna chithunzi chowoneka bwino m'malo opanda kuwala, ndipo chimakhala chofunikira kwambiri chifukwa ma resolution tsopano akupitirira 4MP ndi 8MP.

Pali njira ziwiri zodziwika bwino zochepetsera phokoso pamsika. Yoyamba ndi njira yochepetsera phokoso la nthawi yotchedwa 2D-DNR, ndipo yachiwiri ndi 3D-DNR yomwe ndi njira yochepetsera phokoso la malo.

Kuchepetsa Phokoso la Digito la 2D ndi njira imodzi yodziwika bwino yochotsera phokoso. Ngakhale kuti imapambana pochotsa phokoso pazithunzi, sigwira ntchito bwino kwambiri pakakhala kusuntha kwambiri.

2D DNR imaonedwa ngati njira ya "Kuchepetsa Phokoso la Nthawi". Chomwe chimachitika ndichakuti pixel iliyonse pa chimango chilichonse imayerekezeredwa ndi pixels pa mafelemu ena. Poyerekeza mphamvu ndi mitundu ya pixel iliyonse, n'zotheka kupanga ma algorithms kuti azindikire mawonekedwe omwe angagawidwe ngati "phokoso."

3D-DNR ndi yosiyana chifukwa ndi "kuchepetsa phokoso la malo", komwe kumayerekeza ma pixel mkati mwa chimango chomwecho pamwamba pa kufananiza chimango ndi chimango. 3D-DNR imachotsa mawonekedwe osawoneka bwino a zithunzi zowala pang'ono, imagwira zinthu zoyenda popanda kusiya michira kumbuyo, ndipo mu kuwala kochepa, imapangitsa chithunzi kukhala chomveka bwino komanso chakuthwa poyerekeza ndi chopanda kuchepetsa phokoso kapena 2D-DNR. 3D-DNR ndi yofunika kwambiri popanga chithunzi chowoneka bwino kuchokera ku makamera anu achitetezo pamakina anu owunikira.

Kamera yowunikira yochepetsa phokoso la 3D (3D DNR) imatha kupeza komwe phokoso lili ndikupeza poyerekezera ndikuwunika zithunzi za mafelemu akutsogolo ndi akumbuyo. Kuwongolera, ntchito yochepetsera phokoso la digito la 3D imatha kuchepetsa kusokoneza kwa phokoso la chithunzi chofooka cha chizindikiro. Popeza mawonekedwe a phokoso la chithunzi ndi osadziwika, phokoso la chithunzi chilichonse cha chimango silofanana. Kuchepetsa phokoso la digito la 3D poyerekezera mafelemu angapo oyandikana nawo a zithunzi, chidziwitso chosalumikizana (chomwe ndi phokoso) chidzasefedwa chokha, pogwiritsa ntchito kamera yochepetsera phokoso la 3D, phokoso la chithunzi lidzachepetsedwa kwambiri, chithunzicho chidzakhala chokwanira. Potero kuwonetsa chithunzi choyera komanso chofewa. Mu dongosolo lowunikira la analog high-definition, ukadaulo wa ISP wochepetsa phokoso umakweza ukadaulo wachikhalidwe wa 2D kukhala 3D, ndikuwonjezera ntchito ya chimango chochepetsera phokoso la chimango kutengera kuchepetsa phokoso lamkati mwa chimango choyambirira. Analog HD ISP yasintha kwambiri ntchito za chithunzi chosinthika ndi zina zotero. Ponena za njira yogwiritsira ntchito mphamvu zambiri, analog HD ISP imagwiritsanso ntchito ukadaulo wa interframe wide dynamic, kuti tsatanetsatane wa kuwala ndi mbali zakuda za chithunzicho zikhale zomveka bwino komanso pafupi ndi zotsatira zenizeni zomwe maso a anthu amawona.

Mosasamala kanthu za komwe kwachokera, phokoso la kanema wa digito lingathe kuwononga kwambiri mawonekedwe a kanema. Kanema wokhala ndi phokoso losawoneka bwino nthawi zambiri amawoneka bwino.Njira imodzi yomwe ingathandize kuchita zimenezi ndikugwiritsa ntchito njira yochepetsera phokoso yomwe ili mkati mwa kamera ngati ilipoNjira ina ndiyo kuchepetsa phokoso pambuyo pokonza.

Mu makampani opanga makamera, ukadaulo wochepetsa phokoso la 3D mosakayikira udzakhala njira yodziwika bwino mtsogolomuPamene zinthu zowunikira za analog high-definition zinatuluka, ukadaulo wa ISP wochepetsa phokoso unapeza malo. Mu zida zowunikira za analog high-definition, zimatha kusinthidwa kukhala kamera yapamwamba ya analog pamtengo wotsika, ndipo zotsatira za kanema zitha kukonzedwa ndi 30%. Uwu ndiye ubwino wa ukadaulo uwu. Ntchito yochepetsera phokoso ya digito ya 3D ingathandize makamera a CMOS HD kupeza zithunzi zomwezo kapena zabwino kuposa CCD ya kukula komweko pamalo opanda kuwala kwenikweni. Kuphatikiza ndi mitundu yayikulu ya CMOS, zinthu za CMOS zimagwira ntchito yofunika kwambiri m'makamera a HD. Mwa kuchepetsa kuchuluka kwa deta yamavidiyo kudzera muzithunzi zochepetsera phokoso, motero kuchepetsa kuthamanga kwa bandwidth ndi malo osungira maukonde, sipadzakhala malo a analog pamsika wowunikira wa high-definition.

Poyankha izi, kuti akwaniritse zosowa za makasitomala ambiri a makamera apamwamba kwambiri, Hampo yatsala pang'ono kuyambitsa ma module angapo a makamera okhala ndi ukadaulo wochepetsera phokoso wa 3D, tiyeni tiyembekezere chinthu chathu chatsopano - module ya kamera yochepetsera phokoso ya 3D ikubwera!
