Inzwa yesithombe entsha yakwa-Sony ye-CMOS ine-DRAM yayo

El amandla amancane kubuchwepheshe Kusivumele ukuthi sisondele kuwo wonke lawo madivayisi esiwaphethe ngesandla, emotweni noma esinayo ekhaya, ingasaphathwa eyomkhakha kanye nezinsizakalo eziningi ezisebenzisa ezincane endaweni encane kakhulu. Ubunjiniyela nokukhiqiza kufinyelele ezingeni eliphezulu kangangoba awazi ngempela ukuthi uphahla lwakho luyini.

USony ungomunye walabo abayisa ikati emanzini ezithombeni futhi manje kulapho selikhuphukele khona ezingeni inzwa eyodwa engu-3 ungqimba lwe-BSI CMOS kuma-Smartphones okuthi, ngenxa yobuchwepheshe besimanje, baphathe i-DRAM yabo emathunjini abo.

I-DRAM ngenzwa yesithombe

I-RAM uhlobo lwesitoreji sedatha esisheshayo esisheshayo, kwesinye isikhathi esihlotshaniswa neprosesa namakhompyutha. Kepha AbakwaSony manje basebenzisa izinzuzo yalobo buchwepheshe ukwenza ngcono isivinini sezinzwa zesithombe. Futhi hhayi lokho kuphela, kepha ukwazile ukuyinciphisa ibe ngosayizi wenzwa engafakwa kwi-smartphone.

Umbuzo ovelayo ukuthi kungani ufuna ukusebenzisa i-DRAM noma i-Dynamic RAM ngaphakathi kwenzwa yesithombe. Inhloso ye-RAM ikhulisa ukufundwa kwedatha yenzwa yesithombe, njengoba lolu hlobo lwememori lubhekwa njengobunye besitoreji esisheshayo kanye nobuchwepheshe bokufinyelela obungabizi ngamaphakethe amaningi. Kulo mongo, i-DRAM itholakala ku- "sandwich" phakathi kwesakhiwo sephikseli ye-BSI kanye nongqimba wesifunda ongaphansi olungisa ukucutshungulwa kwesiginali.

I-DRAM ngaleyo ndlela isebenza njengohlobo lwendawo leyo ingafunda ngokushesha idatha eya enzwa ngakho-ke bangehliselwa phansi ku-processor ehamba kancane. Lokhu kusho ukuthi inzwa ingabamba inani elifanayo lemininingwane ye-pixel engxenyeni yesekhondi. Ikakhulukazi ngalesi senzwa, kusho ukuthi amaphikseli ayizigidi eziyi-19,3 angarekhodwa engxenyeni eyi-1/129 yomzuzwana, uma kuqhathaniswa namanani afanayo adingekayo engxenyeni eyi-1/30 yomzuzwana, okuwukukhulisa okukhulu.

Enye inzuzo yokufaka i-DRAM kwenzwa yesithombe ukuthi ungakwazi thatha ukuhamba kancane kuma-fps ayi-1.000 XNUMX ngisho naku-1920 x 1080 (Full HD) izinqumo. Inzwa uqobo lwayo inamandla angama-megapixel angama-21.2 futhi iyakwazi ukuqopha ividiyo engu-4K kuma-FPS angama-60 noma ama-FPS angama-240 nge-HD ephelele. Umthamo wenzwa ye-DRAM yi-1 Gigabit, eyi-125MB.

AbakwaSony abadalulanga ukuthi le sensor izofakwa nini kwi-smartphone, kepha bekungeke kube ukusangana kakhulu ukucabanga ukuthi kungenzeka ube se-Xperia ephezulu ekugcineni kulo nyaka.

I-Sony njengenye yasesiteji

Inkampani yaseJapan iphinde ikhombise ngalobu buchwepheshe ukuthi itholakala ngokuphelele kubo zuza ukwethenjwa ngabakhiqizi abaningi ukuba nesithombe esihle kunazo zonke. Idinga kuphela ukukwazi ukuhlanganisa isoftware edingekayo kububanzi bayo be-Xperia ukuze isebenzise izinzwa zayo ngendlela engcono, ngoba eminye imikhiqizo iyona, ngokususelwa kuma-algorithms, azi ukuthi angayisebenzisa kanjani i-hardware enkulu eyethulwe nguSony .

Kungokunye kokukhubazeka okukhulu uSony nohlobo lwayo lwe-Xperia abenakho, yize muva nje, noma kuzibuyekezo zokuphela okuphezulu okwethulwe ngo-2015, ikhwalithi yezithombe ithuthuke kakhulu. Kunoma ikuphi, kulindeleke okuningi kumenzi waseJapan ngalo mqondo lapho inehadiwe enhle kakhulu futhi neGoogle Pixel, enenye yezinzwa zayo, ine okwamanje ikhamera ehamba phambili yamanje ku-smartphone.

Sizobona kuphela ekupheleni konyaka yini leyo sensor yesithombe ekwazi izoba ne-DRAM, ngakho-ke ngibheke phambili ukubona amandla ayo kuleyo flagship Xperia.
