Chithunzi chatsopano cha Sony cha smartphone cha CMOS chili ndi DRAM yake

El mphamvu zazing'onozing'ono zamakono Zatilola kuyandikira pafupi ndi zida zonse zomwe timanyamula m'manja, m'galimoto kapena kunyumba, osatchulanso zamakampani ndi ntchito zina zomwe zimagwiritsa ntchito zazing'ono pamalo ochepa kwambiri. Umisiri ndi kupanga kwafika pamlingo waukulu kwakuti simukudziwa kuti denga lanu ndi chiyani.

Sony ndiimodzi mwazomwe zimatenga katsayo kupita nayo kumadzi pakujambula ndipo pano ndi pomwe idakwera pamlingo chojambulira chimodzi cha 3-wosanjikiza BSI CMOS kwa mafoni omwe, chifukwa chaukadaulo wamakono, amanyamula DRAM yawo m'matumbo awo.

DRAM muchithunzi chazithunzi

RAM ndi mtundu wosungira kosasunthika kwambiri, komwe nthawi zina kumalumikizidwa ndi ma processor ndi makompyuta. Koma Sony tsopano ikugwiritsa ntchito maubwino ake zaukadaulo uwu kuti uwongolere kuthamanga kwa masensa azithunzi. Osati zokhazo, koma yakwanitsa kuchepetsa kukula kwa sensa yomwe imatha kuphatikizidwa ndi smartphone.

3 wosanjikiza sensa

Funso lomwe limakhalapo ndichifukwa chake mukufuna kugwiritsa ntchito DRAM kapena Dynamic RAM mkati mwazithunzi zazithunzi. Cholinga cha RAM ndi iosachulukitsa kuwerenga kwazithunzi zazithunzi, polingalira za mtundu uwu wokumbukira ngati imodzi mwazomwe zimasungidwa mwachangu posungira ndikusunga matekinoloje omwe ndiotsika mtengo m'matumba ambiri. Poterepa, DRAM ili mu "sangweji" pakati pa kapangidwe ka mapikiselo a BSI ndi gawo loyambira lomwe limayang'anira kukonza kwa siginecha.

DRAM motero imakhala ngati dera lomwe imatha kuwerenga mwachangu zomwe zimapita ku sensa kotero iwo akhoza kutsitsidwa kwa purosesa pang'onopang'ono. Izi zikutanthauza kuti sensa ikhoza kutenga chidziwitso chofanana cha pixel pasekondi imodzi. Makamaka pa sensa iyi, zikutanthauza kuti mapikseli miliyoni 19,3 amatha kujambulidwa mu 1/129 kachigawo kamodzi kokha, poyerekeza ndi ndalama zofananira ndi 1/30 kachigawo kamodzi, ndikokulitsa kwakukulu.

Ubwino wina wophatikiza DRAM muzithunzi zazithunzi ndikuti mungathe kujambula pang'onopang'ono pa ma fps 1.000 ngakhale pamaganizidwe a 1920 x 1080 (Full HD). Chojambulacho chimatha kukhala ndi ma megapixel 21.2 ndipo imatha kujambula kanema wa 4K pa 60 FPS kapena 240 FPS ya Full HD. Mphamvu ya sensa ya DRAM ndi 1 Gigabit, yomwe ili pafupifupi 125MB.

Sony sanawulule pomwe sensa iyi iphatikizidwa mu smartphone, koma sizingakhale zopenga kwambiri kuganiza kuti zingatero khalani pamapeto a Xperia mochedwa za chaka chino.

Sony ngati imodzi mwazinthuzo

Kampani yaku Japan ikuwonetsanso ndi ukadaulo uwu kuti umapezeka Pangani chidaliro cha opanga ambiri kukhala ndi chithunzi chabwino kwambiri. Iyenera kungokhala ndi mapulogalamu oyenerera mu mtundu wake wa Xperia kuti igwiritse ntchito masensa ake mwanjira yabwinoko, popeza mitundu ina ndi yomwe, potengera ma algorithms, imadziwa kugwiritsa ntchito zida zazikulu zoperekedwa ndi Sony .

Ichi ndi chimodzi mwazovuta zazikulu zomwe Sony ndi mtundu wake wa Xperia adakhalapo, ngakhale posachedwapa, ngakhale m'mapulogalamu omaliza omwe adayambitsidwa mu 2015, mtundu wa kujambula wakula kwambiri. Mulimonsemo, zambiri zikuyembekezeredwa kuchokera kwa wopanga waku Japan motere pamene ali ndi zida zabwino kwambiri komanso ngakhale Google Pixel, yomwe ili ndi sensa imodzi, ili nayo pompano kamera yabwino kwambiri zamakono pa smartphone.

Tidzangowona kumapeto kwa chaka Kodi chithunzichi chimatha kuchita chiyani Idzakhala ndi DRAM, ndikuyembekezera mwachidwi kuwona kuthekera kwake mu flagship ya Xperia.


Zomwe zili m'nkhaniyi zikutsatira mfundo zathu za malamulo okonzekera. Kuti mufotokoze cholakwika dinani Apa.
