Isivamvo sokukhanya kwe-ambientikakhulu yenziwe ngamacandelo okukhanya.Amalungu e-photosensitive aphuhliswe ngokukhawuleza, iindidi ezininzi, kwaye zisetyenziswa ngokubanzi.I-sensor yokukhanya okusingqongileyo inokubona imeko yokukhanya ejikelezileyo kwaye yazise i-chip chip ukulungelelanisa ngokuzenzekelayo ukukhanya kwe-backlight ye-monitor ukunciphisa ukusetyenziswa kwamandla kwemveliso.Kwelinye icala, inzwa yokukhanya kwe-ambient inceda umboniso ngomfanekiso othambileyo.Xa ukukhanya kwendalo kuphezulu, umboniso wekristale elulwelo usebenzisa isivamvo sokukhanya okujikeleze uya kulungelelanisa ngokuzenzekelayo ekukhanyeni okuphezulu.Xa indawo yangaphandle imnyama, umboniso uya kulungelelaniswa kukukhanya okuphantsi.

Umgama wokukhanya usondele kwi-chip sensor -WH APS 4530A luhlobo lokukhanya kwi-converter yedijithali.Idibanisa iisensom zokukhanya zendalo esingqongileyo eziphambili, izinzwa eziphambili kunye nezibane eziphezulu ze-infrared ze-LED.Isihluzi sakhelwe-ngaphakathi ukucinezela infrared, kwaye sinika ispectrum kufutshane nezenzo zamehlo omntu.I-ALS inokusebenza phantsi kobumnyama ukuya ekukhanyeni kwelanga, kwaye uluhlu olukhethiweyo lokuchongwa malunga ne-40dB.Imveliso ye-Dual-channel (iliso lomntu kwaye icacile), ukwenzela ukuba i-ALS inomlinganiselo wokukhanya okulungileyo phantsi kweemeko ezahlukeneyo zokukhanya.Isihluzi se-940nm sakhiwe-kwinzwa (PS) yokukhanya okusingqongileyo.Ke ngoko, i-PS inokubona ukukhanya kwe-infrared ye-reflex, enokuchaneka okuphezulu kunye nokuchasana okugqwesileyo.I-WH4530A inomsebenzi wokuphazamiseka ocwangcisekileyo, kwaye inomda osekelwe kwi-ALS kunye ne-PS.

Izinzwa zokukhanya okusingqongileyo zinobumnyama obuncinci bangoku, impendulo yokukhanya ephantsi, uvakalelo oluphezulu, kunye nokutshintsha komgca kunye nokukhanya kokukhanya kwangoku;eyakhelwe-kwi-double-sensitive element, i-attenuation ngokuzenzekelayo kufuphi ne-infrared, impendulo ye-spectral kufuphi ne-curve yokusebenza kwamehlo omntu (omnyama: ijika lokuphendula iliso lomntu, iBlue: i-Optical resistance response curve, eluhlaza: i-ambient light response curve);Olunye uqwalaselo lolunye uqwalaselo xa ukhetha inzwa yokukhanya efanelekileyo kukukhetha inzwa enempendulo efanelekileyo yespectrum.I-PIN yesiqhelo ye-Photoami diode okanye ukuxhathisa kwamehlo (i-passive okanye esebenzayo) ngokwayo inoluhlu lokuphendula olubanzi kakhulu, kubandakanya imitha ye-IR kunye nemitha ye-UV.
