Samsung yakaunza itsva 200MPx photo sensor mavhiki mashoma apfuura ISOCELL HP3. Iyi ndiyo sensor ine diki pixel saizi zvachose. Ikozvino, iyo yeKorea tech hofori yataura nezve budiriro yayo kuburikidza nevagadziri kubva kuSystem LSI division uye Semiconductor R&D Center.
Sensor yemufananidzo (kana photosensor) isystem semiconductor inoshandura mwenje unopinda muchishandiso kuburikidza nekamera lenzi kuita masaini edhijitari. Masikirwo emifananidzo anovakwa mune zvese zvigadzirwa zvemagetsi zvine kamera, senge digitaalinen makamera, malaptop, mota uye, hongu, mafoni. Iyo ISOCELL HP3, yakaunzwa neSamsung muna Chikumi, iphotosensor ine 200 miriyoni 0,56 micron pixels (iyo indasitiri idiki pixel saizi) mune 1/1,4 ″ optical fomati.
"Nezvidiki zvidiki pixel saizi, saizi yemuviri ye sensor uye module inogona kuderedzwa, iyo inobvumirawo ukuru uye upamhi hwe lens kudzikiswa," anotsanangura mugadziri Myoungoh Ki kubva kuSamsung's System LSI division. "Izvi zvinogona kubvisa zvinhu zvinokanganisa dhizaini yechigadzirwa, senge kamera inobudikira, pamwe nekuderedza kushandiswa kwemagetsi," akadaro. akawedzera.

Nepo mapikiseli madiki achibvumira mudziyo kuve mutete, kiyi ndeyekuchengetedza mhando yemufananidzo. ISOCELL HP3, yakagadziridzwa ichishandisa matekinoroji echizvino-zvino, ine 12% diki pixel saizi pane yekutanga Samsung 200MPx photosensor. ISOCELL HP1, inogona kuderedza nzvimbo yekamera mune nharembozha nekusvika 20%. Kunyangwe idiki pixel saizi, ISOCELL HP3 yakagadziridzwa ichishandisa tekinoroji inokwirisa yavo Yakazara Zvakanaka Capacity (FWC) uye inoderedza kurasikirwa kwekunzwa. Diki pixel saizi yakanakira kugadzira zvidiki, zvidiki zvidiki, asi zvinogona kukonzera kushoma mwenje kupinda muchishandiso kana kukanganisa pakati peevakidzani pixels. Nekudaro, kunyangwe neizvi, Samsung yakakwanisa kutsungirira, uye maererano naKi, ndeye nekuda kweiyo proprietary tekinoroji kugona kweiyo hofori yeKorea.

Samsung yakakwanisa kugadzira madziro emuviri pakati pepixels akatetepa uye akadzika uchishandisa Yakazara Depth deep trench isolation (DTI) tekinoroji, iyo inovimbisa kushanda kwepamusoro kunyangwe pahukuru hwe 0,56 microns. DTI inogadzira chikamu chakasarudzika pakati pemapikseli anoita semadziro anodzivirira kudzivirira kurasikirwa kwechiedza uye kunatsiridza mashandiro ekuona. Mugadziri Sungsoo Choi weSamsung's Semiconductor R&D Center anofananidza tekinoroji nekuvaka chivhariso chakatetepa pakati pemakamuri akasiyana muchivakwa. "Mukutaura kwevanhu, zvakangofanana nekuedza kugadzira madziro akatetepa pakati pekamuri yako nekamuri rinotevera pasina kukanganisa mwero wekudzivirira inzwi," akatsanangura.
Unogona kufarira
Super Quad Phase Detection (QPD) tekinoroji inobvumira ese mazana maviri emamiriyoni pixels kuti atarise nekuwedzera kusimba kweiyo autofocus pixels kusvika 200%. QPD inopa kukurumidza uye kwakaringana autofocus basa nekushandisa lenzi imwe pamusoro pemapikisi mana, ichibvumira kuyerwa kwese kwechikamu mutsauko wekuruboshwe, kurudyi, kumusoro uye pasi pechinyorwa chiri kutorwa mifananidzo. Haisi chete iyo autofocus yakanyanya kurongeka husiku, asi iyo yepamusoro resolution inochengetedzwa kunyangwe kana yaswededzwa mukati. Kugadzirisa dambudziko rekushomeka kwemhando yemifananidzo munzvimbo dzakadzika-mwenje, Samsung yakashandisa hunyanzvi hwepixel tekinoroji. "Takashandisa yakagadziridzwa vhezheni yeTetra2pixel tekinoroji yedu, iyo inosanganisa mana kana gumi nematanhatu ari padyo mapikisiki kuita senge pixel hombe munzvimbo dzisina chiedza," Choi akadaro. Iyo yakagadziridzwa pixel tekinoroji inoita kuti zvikwanise kupfura mavhidhiyo mu8K resolution pa30 fps uye mu4K pa120 fps pasina kurasikirwa nemunda wekuona.
Ki naChoi vakatiwo vakasangana nezvipingamupinyi zvakati wandei mukugadzirwa kweiyo photosensor nyowani (kunyanya mukuita tekinoroji yeDTI, iyo yakashandiswa neSamsung kekutanga), asi kuti vakakundwa nekuda kwekubatana kwe zvikwata zvakasiyana-siyana. Zvisinei nekukura kuri kuda, hofori yeKorea yakaunza sensor nyowani isingasviki gore mushure mekuzivisa yayo yekutanga 200MPx sensor. Ndeipi smartphone iyo ichatanga mairi haisati yanyatsojeka panguva ino.
