CMOS--matrix: izici, imisebenzi kanye nokusebenza zedivayisi

CMOS--matrix - idivayisi umsebenzi wakhe omkhulu yilona ibhadalele nemingcele athile imisebe yokukhanya ukuthi eze phezu. matrices amabili ejwayelekile elisetshenziswa yesimanje izithombe kanye video imishini: CMOS futhi be-CCD. Lesi sihloko Sizokwenza ngokuqhathanisa ubuchwepheshe ezimbili.

ulwazi olujwayelekile

Ngakho, be-CCD--matrix. Lolu hlobo ekuqaleni kubhekwa izinga eliphezulu kakhulu, kodwa futhi amandla khudlwana futhi kuyabiza. Umgomo we operation amadivayisi ezinjalo kusekelwe ukuqoqwa lonke isithombe version-analog, kulandele ibhadalele. CMOS-matrix, ngokungafani esincintisana yayo, digitizes kwe-pixel ngayinye.

Ukuqhathanisa ubuchwepheshe ezimbili

CMOS-amadivaysi babe energopoteblyayuschimi ekuqaleni kancane futhi ezishibhile, lokhu kuyiqiniso ikakhulukazi ekukhiqizeni usayizi kumadivayisi ezinkulu, kodwa ziphansi izinga be-CCD. Kuze kube namuhla, be-CCD-ubuchwepheshe maningi eliphezulu izithombe, bajwayele emikhakheni ehlukahlukene yesayensi kanye umkhakha, lapho izinga yesithombe eziphoqelelwe izidingo eliphakeme. Ngokwesibonelo, imithi.

Eminyakeni yamuva, lolu hlobo imishini is kakhulu ziyancipha energy ukusetshenziswa kanye izindleko, kodwa futhi CMOS--matrix sakhombisa inqubekela phambili ebonakalayo ekuthuthukisweni yayo. Isibonelo, lwapheleliswa sethula ku ileveli entsha ikhwalithi yesithombe ejwayelekile. Ngaphezu kwalokho, intuthuko kwezobuchwepheshe enkulu ekwakhekeni izinzwa esekelwe CMOS-ubuchwepheshe lwenziwe, okungukuthi i-pixel ye isithombe ngasinye seyenziwe sokufunda Transistor amplifier. Lokhu kuye kwenza ukuba ukukhiqiza icala voltage ukuguqulwa ngqo endaweni. Nale CMOS--matrix isibe belingana be-CCD-technology. Futhi manje amadivaysi esimanjemanje kakhulu kusekelwe idivayisi esekelwe CMOS.

Izinzuzo CMOS-ubuchwepheshe

Kufinyeta okungenhla, singakwazi fingqa izinzuzo mishini. Lokhu low power ukusetshenziswa kwimodi static, eziphansi yokukhiqiza (ikakhulukazi uma ucabangela lesinqumo eliphezulu CMOS--matrix). Kodwa inzuzo ebaluleke kunazo zonke, ikhono ukunikeza out ngomumo isignali digital, okuyinto akudingi ukuguqulwa eyengeziwe.

Ukusetshenziswa CMOS-ubuchwepheshe bama-computer

Ngamunye umsebenzisi imishini yesimanje ikhompyutha nsuku ebhekene nedivaysi ezifana web-ikhamera. Kodwa abaningi abazi ukuthi kusekelwe isimiso CMOS-technology. I-Web-ikhamera isetshenziswa njengoba idivayisi ngabanye ukusebenza, futhi esishunyekwe isibonelo e-laptops. Amadivayisi anjalo zenzelwe ukusebenza kwenethiwekhi multimedia izicelo. Ukwakheka umkhiqizo wathi kuhlanganisa: afanayo lens, a bamba ikhadi levidiyo, isihlungi optical, kweyunithi isithombe kokucindezelwa, processor, flash inkumbulo, web-iseva, futhi inethiwekhi esibonakalayo. I-matrix isisekelo sanoma ibuphi camcoder noma fotoappatara. Ngoba izinga isithombe ngobulili kuzoncika isixazululo zedivayisi. Lokhu ipharamitha ngokuvamile e amakhamera iwebhu in the uhla kusuka megapixels 0.1 2. Nokho, imikhiqizo eminingi kuba 0.3 megapixel. Esinye isici sokunquma webcam wenza Uhlaka format. Ethandwa kakhulu kuba matrix CMOS 1/4. Kunezinye izakhiwo, kodwa abaqiniseki ezivamile (isib, 1/3, 1/2 noma 2/3 ngamasentimitha).
