Ubuchwepheshe be-Apple-sensor ezintathu bunelungelo lobunikazi bama-smartphone

I-Apple inelungelo lobunikazi lenzwa entsha yesithombe efaka isihlukanisi sokukhanya esikwazi ukuthumela ukukhanya kumalungu amathathu we-pixel we-sensor ngombala ngamunye wesikhala se-RGB.

Sekuyisikhashana kusukela izwe lenzwa yesithombe laguqulwa. Yize izinkampani zinelungelo lobunikazi lobuchwepheshe obuningi obuthakazelisayo, amayunithi avame kakhulu ukuhlelwa kweBayer. I-Sigma yenza inqubekela phambili eningi ngezinzwa zayo eziyizendlalelo ezintathu, kuyilapho uFujifilm enconywa ngekhwalithi yesithombe enikezwe izinzwa ze-X-Trans.

Kodwa-ke, kudingeka okuningi futhi kubonakala sengathi i-Apple ihlose ukubuyisa inguqulo yobuchwepheshe engakatholi ukuthandwa okuningi. Umenzi we-smartphone unelungelo lobunikazi inzwa ekhethekile efaka iphrism ehlukanisa ukukhanya, ithumela imibala ehlukene yokukhanya eziteshini zemibala emithathu.

I-Apple inelungelo lobunikazi lemodyuli entsha yekhamera yekhamera, efaka iprism ezohlukanisa ukukhanya futhi izoyithumela kwizendlalelo ezintathu zamaphikseli ahlukene - ungqimba ngalunye lwemibala yesikhala se-RGB.

I-Apple patent-sensor patent ichaza inzwa yesithombe enokuhlukaniswa okulula

Ibizwe njenge-Apple inzwa ezintathu, lokhu ubuchwepheshe bunelungelo lobunikazi e-US. Ngamazwi alula, inzwa empeleni inemigqa eminingi, njengoba inamashidi amathathu wamaphikseli: elilodwa ngombala oluhlaza okwesibhakabhaka, elilodwa ngombala oluhlaza, nelokugcina ngombala obomvu.

Ukuze kuqinisekiswe ukuthi ukukhanya okukhulu ngangokunokwenzeka kushaya isiteshi ngasinye, kuzobekwa iphrism phakathi kwezendlalelo zamaphikseli. Lapho isibani sesishaye isihlukanisi, umbala ngamunye uzothunyelwa esiteshini sawo esihambisanayo.

Lokhu kusho ukuthi ukukhiqizwa kabusha kombala kuzothuthukiswa kunobuchwepheshe bamanje. Ngaphezu kwalokho, ngeke kube khona ukulahleka okuncane, ngoba asikho isidingo sesihlungi seBayer, esivame ukuvimba ingxenye yokukhanya okungenayo.

I-Apple kungadingeka ukuthi yenze ama-smartphones ayo abe makhulu futhi abe mkhulu ukuze enze indawo yobuchwepheshe bayo bezinzwa ezintathu.

Kukhona izingqinamba ezimbalwa okwamanje. Ubuchwepheshe be-Apple-sensors three bubhekiswe kuma-smartphones. Inkampani ezinze e-US yaziwa ngokwethula izingcingo eziphethe okuncane futhi, ngokwahlulela ngencazelo yelungelo lobunikazi, le sensor yezithombe izokala cishe ngo-18mm kuye ku-32mm ubude.

Usayizi omkhulu ungaba wusizo ngoba lonke uhlelo luzofaka phakathi zombili ukuzinza kwesithombe nelensi enokusondeza okubonakalayo. Kodwa-ke, kusazobonakala ukuthi ngabe i-Apple izoyithola yini indlela yokunciphisa lonke uhlelo noma izokwenza amafoni ayo abe made futhi abe mkhulu.

Amakhamera amathathu-CCD ayafana, kanti iPanasonic isebenza kumaMicro Splitters

Ubuchwepheshe obufanayo busetshenzisiwe kumakhamera ama-CCD amathathu. Ukukhanya okungenayo kushaya i-prism ekhethekile eqondisa ukukhanya kumashidi ama-pixel amathathu ahlukene. Ishidi ngalinye le-pixel lihambisana nombala wesikhala se-RGB. Kodwa-ke, lobu buchwepheshe abukho kakhulu, njengoba ubuchwepheshe obujwayelekile be-CMOS kanye ne-CCD kuyizinhlelo ezisetshenziswa kakhulu emhlabeni wanamuhla we-digital imaging.

Yile ndlela i-prism ehlukanisa ukukhanya esebenza ngayo ngaphakathi kwekhiyubhu. Uhlelo olufanayo lunikezwe ilungelo lobunikazi yi-Apple.

Enye inkampani izama iziqhekezi ezikhanyayo yiPanasonic. Umenzi wembule ubuchwepheshe obuhlinzeka ngokuthuthuka kokudlulisa ukukhanya kubonga entweni ebizwa ngeMicro Color Splitters.

Ubuchwepheshe bePanasonic busebenzisa ukwahlukanisa futhi inzwa yayo ingcono kabili njengenzwa esekwe eBayer uma kukhulunywa ngokusebenza okukhanyayo okuphansi. Izinkampani zenza amalungelo obunikazi obunikazi ngaso sonke isikhathi, ngakho-ke ungabambi umoya ngokubona bonke lobu buchwepheshe kumakhamera azokhishwa kungekudala.
