Kodi Ndigwiritse Ntchito Kuchepetsa Phokoso la 3D mu Kamera?

Monga momwe tikudziwira kuti phokoso ndi chinthu chosapeŵeka cha ma amplifiers mu makamera otetezera. Kanema "phokoso" ndi mawonekedwe a "static" omwe amapanga chifunga, timadontho, ndi fuzz zomwe zimapangitsa chithunzi cha kamera yanu yowunikira kuti zisamveke bwino mukamawala pang'ono. Kuchepetsa phokoso ndikofunikira kwambiri ngati mukufuna chithunzi chowoneka bwino m'malo opepuka, ndipo chimakhala chofunikira kwambiri popeza malingaliro akupitilira 4MP ndi 8MP.

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

2D Digital Noise Reduction ndi imodzi mwa njira zofunika kwambiri zochotsera phokoso. Ngakhale kuti ndi bwino kuchotsa phokoso pazithunzi, izo sizichita ntchito yabwino muzosankha zapamwamba komanso pamene pali zoyenda zambiri mozungulira.

2D DNR imatengedwa ngati njira ya "Temporal Noise Reduction". Zomwe zimachitika ndikuti pixel iliyonse pa chimango chilichonse imafanizidwa ndi ma pixel pamafelemu ena. Poyerekeza kukula kwake ndi mitundu ya ma pixel onsewa, ndizotheka kupanga ma aligorivimu kuti muzindikire mawonekedwe omwe atha kugawidwa ngati "phokoso."

3D-DNR ndi yosiyana chifukwa ndi "kuchepetsa phokoso la malo", yomwe imafanizira ma pixel omwe ali mkati mwa chimango chomwecho pamwamba pa kufananitsa chimango ndi chimango. 3D-DNR imachotsa mawonekedwe owoneka bwino azithunzi zopepuka, imagwira zinthu zoyenda popanda kusiya michira, ndipo pakuwala pang'ono, imapangitsa chithunzi kukhala chomveka bwino komanso chakuthwa poyerekeza ndi kusachepetsa phokoso kapena 2D-DNR. 3D-DNR ndiyofunikira kuti mupange chithunzi chomveka bwino kuchokera ku makamera anu achitetezo panjira yanu yowunikira.

Kamera yowunikira ya 3D (3D DNR) yowunikira imatha kudziwa malo a phokoso ndikuipeza poyerekezera ndi kuyang'ana zithunzi za mafelemu akutsogolo ndi kumbuyo Kuwongolera, ntchito yochepetsera phokoso la digito ya 3D imatha kuchepetsa kusokoneza kwa phokoso la chithunzi chofooka cha chizindikiro. Popeza kuwoneka kwaphokoso lachifaniziro kumangochitika mwachisawawa, phokoso lachithunzi chilichonse silifanana. Kuchepetsa phokoso la digito la 3D poyerekeza mafelemu angapo oyandikana a zithunzi, zambiri zomwe sizingadutse (zomwe ndi phokoso) zidzasefedwa, pogwiritsa ntchito kamera yochepetsera phokoso la 3D, phokoso lazithunzi lidzachepetsedwa kwambiri, chithunzicho chidzakhala chokwanira. Potero kuwonetsa chithunzi choyera komanso chofewa.Munjira yowunikira kwambiri ya analogi, ukadaulo wochepetsera phokoso wa ISP umakweza luso lakale la 2D kukhala 3D, ndikuwonjezera ntchito ya chimango kuti muchepetse phokoso pamaziko a phokoso loyambirira lamkati mwa chimango. kuchepetsa. Analogi HD ISP yasintha kwambiri magwiridwe antchito azithunzi zosinthika ndi zina. Pankhani yakusintha kwakukulu, analogi HD ISP imagwiritsanso ntchito ukadaulo wa interframe wide Dynamic, kotero kuti tsatanetsatane wa mbali zowala ndi zakuda za chithunzicho zimveke bwino komanso pafupi ndi momwe maso amunthu amawonera.

Mosasamala kanthu za gwero, phokoso la kanema wa digito limatha kusokoneza kwambiri mawonekedwe azithunzi. Kanema wokhala ndi phokoso locheperako nthawi zambiri amawoneka bwino.Njira imodzi yokwaniritsira izi ndikugwiritsa ntchito kuchepetsa phokoso la kamera ikapezeka. Njira ina ndiyo kugwiritsa ntchito kuchepetsa phokoso pokonza pambuyo.

Pamakampani opanga makamera, ukadaulo wochepetsera phokoso wa 3D mosakayikira ukhala njira yodziwika bwino mtsogolo.Pamene zinthu zowunikira kwambiri za analogi zidatuluka, ukadaulo wochepetsa phokoso wa ISP udapeza malo. Mu zida zowunikira kwambiri za analogi, zitha kukwezedwa ku kamera yamtundu wapamwamba wa analogi pamtengo wotsika, ndipo tanthauzo la vidiyo limatha kupitilizidwa ndi 30%. Uwu ndiye mwayi waukadaulo uwu. Ntchito yochepetsera phokoso ya digito ya 3D imatha kupangitsa kuti makamera a CMOS HD apeze zithunzi zofananira kapena zabwinoko kuposa za CCD za kukula komweko m'malo owunikira pang'ono. Kuphatikizidwa ndi kuchuluka kwamphamvu kwa CMOS, zinthu za CMOS zimagwira ntchito yofunika kwambiri pamakamera a HD. Mwa kuchepetsa kuchuluka kwa deta ya kanema kudzera muzithunzi zochepetsera phokoso, ndipo motero kuchepetsa kupanikizika kwa bandwidth pa intaneti ndi kusungirako, sipadzakhalanso malo a analogi mumsika wapamwamba wowunika.

Poyankha zochitika zazikuluzikuluzi, kuti akwaniritse zosowa za makasitomala ambiri a makamera apamwamba kwambiri, Hampo yatsala pang'ono kukhazikitsa ma modules a kamera ndi teknoloji yochepetsera phokoso la 3D, tiyeni tiyembekezere mankhwala athu atsopano -3D kuchepetsa phokoso kamera. module ikubwera!
