Uguquko lokuthwebula izithombe ngekhompyutha: ukuthi ama-algorithms we-multi-frame synthesis anqamula kanjani imikhawulo yehadiwe yamakhamera we-smartphone

Enkathini yanamuhla yokuphindaphinda okuqhubekayo kubuchwepheshe bokuthwebula be-smartphone, ama-algorithms wokuhlanganiswa kohlaka oluningi acupha buthule uguquko ekuthwebuleni izithombe ngekhompyutha. Lapho ukuthuthukiswa kwezingxenyekazi zekhompuyutha zendabuko kuhlangabezana nemikhawulo ebonakalayo, lo mgogodla, ngokusebenzisa izindlela zokuqamba ezintsha ezichazwe yisoftware, uhlinzeka ngezixazululo ezihlelekile zokulimala kwehadiwe kumakhamera we-smartphone.

Lobu buchwepheshe buthwebula amafreyimu amaningi ezithombe ngokulandelana okusheshayo, kusetshenziswa ama-algorithms ukuqondisa ngobuhlakani nokuhlanganisa ulwazi lweleveli yephikseli. Uma sithatha inzwa ye-iPhone 15 Pro Maxs 48-megapixel njengesibonelo, ubuchwepheshe bayo be-Quad Pixel bungakwazi ukuthwebula izithombe zefomethi engu-12 RAW ngamasekhondi angu-0.5, kuzuze ukukhanya okuphezulu kanye nomthelela wesithombe sokugcinwa kwemininingwane emnyama ngobubanzi obuguqukayo. amakhamera i-algorithm yokwenza kahle. Le modeli yokuthwebula yekhompyutha eyeqa imikhawulo yezingxenyekazi zekhompuyutha ezivamile ithuthukise amandla okulawula umsindo omakhalekhukhwini ezindaweni ezinokukhanya okuphansi ngamaphesenti angaphezu kuka-40%.

Imikhawulo ye-Dynamic Range: Izinzwa zendabuko zivame ukulahlekelwa imininingwane ezigcawini ezinakho kokubili ukukhanya okunamandla nethunzi. I-algorithm ye-HDR ye-Google Pixel 8 Pro ithuthukisa ububanzi obuguquguqukayo ukuya ku-4EV ngokuqondisa kwezinhlaka eziningi, kuzuzwe ukukhiqizwa kabusha kombala okungokoqobo okuseduze nokubona komuntu.

I-Bottleneck Yokusebenza Kokukhanya Okuphansi: I-Galaxy S24 Ultra isebenzisa inzwa engu-200-megapixel ebhangqwe nobuchwepheshe bokunciphisa umsindo wezinhlaka eziningi ukuze kugcinwe ikhwalithi yesithombe esebenzisekayo ezindaweni ezidlulele ze-ISO 02400.

Imikhawulo Yokuqiniswa Kwesithombe Esibonakalayo: I-super-algorithm ye-Vivo X100 enezinhlaka eziningi, ngobuchwepheshe besinxephezelo esinyakazayo, inyusa izinga lempumelelo yokuthwebula ophathwa ngesandla ukuya ku-92%, yeqa imikhawulo ebonakalayo yokuqina kwesithombe.

Ubuchwepheshe bamanje buthuthuke bafinyelela esigabeni sokuhlanganisa ohlaka oluningi oluqhutshwa yi-AI. I-OPPO Thola i-X7's AI imaging brain ingakhetha ngokuzenzakalelayo isu elihle kakhulu lokuhlanganisa ngokwendawo, izuze imodi yesigcawu sasebusuku esisheshayo esingu-0.6-sesekhondi. Lolu hlobo lokuqanjwa kabusha kwe-algorithmic lunike amandla omakhalekhukhwini ukuthi benze inqubekelaphambili ezindaweni ezimfushane zezingxenyekazi zekhompuyutha ezivamile njengokuthwebula ezemidlalo kanye nekhwalithi yesithombe ngocingo.

Ucwaningo lwemakethe lubonisa ukuthi amamodeli ahlonyiswe ngobuchwepheshe bokuhlanganisa ozimele abaningi anesilinganiso samaphuzu angu-23 ngaphezu kwamamodeli endabuko ku-DxOM. Ngokuthuthukiswa kwamandla wekhompuyutha ye-chip nokuphindaphinda kwe-algorithm, ikusasa lokuhlanganiswa kozimele abaningi lizothuthukela ekucutshungulweni kwevidiyo kwesikhathi sangempela kanye nokuhlanganisa okusebenzisana kwamakhamera amaningi I-Huawei Mate 70 uchungechunge 'umsebenzi wokuvula wamakhamera amaningi ngesikhathi esisodwa usuvele ubonise amandla okusebenza okuhlanganiswa kwedatha yezinzwa eziningi.

Lapho ukuthuthukiswa kuhlangabezana nezingqinamba ezibonakalayo, ama-algorithms okuhlanganiswa kwezinhlaka eziningi ahlela kabusha imithetho yezithombe ze-smartphone ngokuchaza ukuthwebula izithombe kusofthiwe. Lobu buchwepheshe abuphuli nje kuphela imikhawulo yezingxenyekazi zekhompuyutha zendabuko kodwa futhi bungenisa inkathi entsha yokuthatha izithombe ngekhompyutha. Kubathengi, ukuqonda lokhu kuthambekela kwezobuchwepheshe kuzokusiza wenze ukukhetha unolwazi lapho uthenga i-smartphone.
