Ukuhlaziya okujulile kobuchwepheshe bokulinganisa umbala wamakhamera amaningi we-smartphone

Kubuchwepheshe banamuhla be-smartphone obuvela ngokushesha, amasistimu amakhamera amaningi abe indinganiso yamamodeli aphambili. Kodwa-ke, indaba yokuchezuka kombala phakathi kwamalensi ihlale ihlupha ulwazi lomsebenzisi. Lesi sihloko sizongena kubuchwepheshe obuyinhloko be Amakamelo amaningi ukusebenzisana - ukulinganiswa kombala, nokuhlaziya izinselele zayo zobuchwepheshe nezisombululo zemboni.

Ama-smartphones esimanje ngokuvamile ahlome ngamakhamera amaningi, njengekhamera eyinhloko, i-ultra-wide angle, ne-telephoto lens. Ilensi ngayinye inamamodeli ahlukene, imiklamo yokubona, nama-algorithms wokucabanga. Lapho abasebenzisi beshintsha amalensi, kungase kube khona ukweqa okuphawulekayo kombala nokugqamayo, okugqama kakhulu ezimeni zokukhanya eziyinkimbinkimbi.

Izinselelo ezibalulekile zihlanganisa:

1.Umehluko wempendulo yezinzwa: Izinzwa ezihlukene zinokuzwela okuhlukile kumibala eyinhloko ye-RGB, okuholela ekuphambukeni kwemvelo ekukhiqizeni kabusha kombala.

2. Umehluko wendlela yokubona: Umehluko ekufakweni kwelensi nokokusebenza kwelensi kungathinta ukudluliswa kokukhanya, ngaleyo ndlela kushintshe ukusebenza kombala.

3. Ukuhambisana kwe-algorithm: Ama-algorithms athuthukiswe ngokuzimela kukhamera ngayinye (njenge-HDR, ukuncishiswa komsindo) angase angqubuzane lapho esebenza ndawonye.

Ukuxazulula lezi zinkinga ezingenhla, abakhiqizi be-smartphone nabakhiqizi bama-chip (abafana ne-Qualcomm, i-MediaTek) bathuthukise ngokuhlanganyela ubuchwepheshe bokulinganiswa kwe-multi-dimensional:

1. Ukulinganisa umbala wezingxenyekazi zekhompuyutha

Ukufanisa i-matrix yombala: Nge-spectrometer yaselabhorethri ukuze kuqoqwe idatha yokusabela kombala yelensi ngayinye, sungula i-matrix yokuguqulwa kwezibalo, futhi uguqule isikhala sombala sezinzwa ezihlukene kusizinda sombala esijwayelekile (njenge-sRGB/P3).

Ukuvumelanisa ibhalansi emhlophe: Ukusebenzisa inzwa yokushisa kombala noma i-algorithm ukuvumelanisa amapharamitha ebhalansi emhlophe yelensi ngayinye ngesikhathi sangempela ukuze kuncishiswe umthelela wezinguquko zokukhanya kwe-ambient kumbala.

2.Ukwenziwa ngcono kwe-algorithm yesoftware

Ukuqondanisa kwephoyinti lesici: Ngobuchwepheshe bokubhaliswa kwesithombe, khomba amaphuzu ezici athwetshulwe amalensi ahlukene ngaphansi kwesigcawu esifanayo, bese usungula ubudlelwano bemephu bezinga le-pixel.

Ukuzuza okunamandla: Ngokuhambisana nomehluko wokukhanya kwendawo, lungisa ngamandla i-ISO namapharamitha okuchayeka welensi ngayinye ukuze ugweme ukuchayeka ngokweqile ezithombeni ezinhle kakhulu noma umsindo ezindaweni ezimnyama.

3.Ukunika amandla okufunda ngomshini

Imodeli yokulinganisa eshayelwa idatha: Sebenzisa inombolo enkulu yedatha yokudubula yangempela ukuze uqeqeshe inethiwekhi ye-neural ukuze ufunde ukuchezuka kombala wamalensi ahlukene kuzigcawu eziyinkimbinkimbi, futhi uzuze isinxephezelo esivumelana nezimo.

I-algorithm yokuqaphela isigcawu: Khomba uhlobo lwesigameko nge-AI (njengesigcawu sasebusuku, ukuma ngobude) shayela amasu okulinganisa athile, futhi uthuthukise umthelela wokulungiselelwa okuqondisiwe.

1.I-Huawei XD Fusion Pro: ubuchwepheshe bokuhlanganisa isizinda se-RAW enamakhamera amaningi, yethula ukuhlukaniswa kwe-scece semantic ekulinganisweni kombala, futhi kuzuzwe ukuhlanganisa umbala phakathi kobude obuhlukile bokugxila.

I-2.Apple Deep Fusion: ubuchwepheshe bokuhlanganisa ozimele abaningi, obuhlanganiswe ne-ISP kanye ne-neural engine, ukuze kuthuthukiswe ukushintshwa kombala ngaphansi kokubambisana kwamakhamera amaningi.

3.I-Samsung Multi-Aperture Ngokulungiswa kokuvula okubonakalayo kanye nokuxhumanisa amakhamera amaningi, gcina ukufana kombala ngaphansi kwezimo ezihlukene zokukhanyisa.

Ukungaguquguquki kombala kuwumkhawulo oyinhloko wolwazi lwesistimu yamakhamera amaningi. Ukuphumelela kwayo kwezobuchwepheshe akuncikile kuphela ekuthuthukisweni kwehadiwe kodwa futhi kudinga ukuhlanganiswa okujulile kwama-algorithms nedatha. Ngobuchwepheshe be-AI nobuchwepheshe bezinzwa, ikusasa lokusebenzisana kwamakhamera amaningi lizothuthukela ekumeleleni imibala ehlakaniphe kakhulu nengokwemvelo.
