CMOSka-furta: Tilmaamo, hawlaha iyo hawlgallada ee qalabka

CMOSka-furta - qalab Hawsha ugu weyn waa digitization ee beegyada uu qaar ka mid ah rays iftiinka iman dushiisa. laba matrices caadiga ah loo isticmaalo qalabka sawir iyo video casriga ah: CMOSka iyo CCD. Maqaalkani waxa uu u hibeeyeen ilaa ay barbar oo ka mid ah laba teknoolajiyada.

warbixin guud

Sidaas daraaddeed, CCD-furta. Noocaan waxaa markii hore loo arkaa ugu tayada sareeya, laakiin sidoo kale ka badan oo tamar-degdeg ah oo qaali ah. Mabda'a hawlgalka qalabka sida ku salaysan yahay ururinta sawir oo dhan in version analog ah, raaceen by digitization. CMOSka-furta, ka duwan ay tartan, digitizes pixel walba si gaar ah.

Marka la barbardhigo A ka mid ah laba teknoolajiyada

CMOSka-qalabka ahaayeen energopoteblyayuschimi hore ka yar oo raqiis ah, taasi waa run gaar ahaan la-soo-saarka ee qalabka size waaweyn, laakiin waxay yihiin liita tayada CCD. Ilaa maantadan la joogo, CCD-technology yihiin images tayo sare leh ka badan, waxay waxaa loo isticmaalaa in beeraha kala duwan ee sayniska iyo warshadaha, halkaas oo tayada image ku soo rogay shuruudaha ugu sareeya. Tusaale ahaan, in dawada.

Sanadihii la soo dhaafay, noocan ah qalabka waxaa si weyn u dhimay isticmaalka tamarta iyo kharashka, laakiin sidoo kale CMOSka-furta sameeyey horumar la taaban karo ee dhinaca horumarinta. Tusaale ahaan, waxaa la sugay bilaabay heerka cusub ee Heerka tayada image. Intaas waxaa sii dheer, kacaanka farsamada ee soo saaridda dareemayaal ku salaysan CMOSka-technology ayaa la sameeyey, kuwaas oo in pixel kasta image ayaa lagu fulin waayo reading kordhiyo transistor. Tani ayaa loo ogol yahay in ay soo saaraan diinta danab lacag si toos ah meesha ugu. Iyada oo ay taasi CMOSka-furta waxa uu noqday par leh CCD-technology. Haddaba qalabka ugu casrisan ku saleysan yahay qalab ku salaysan CMOSka.

Faa'iidooyinka CMOSka-technology

Koobaya kor ku xusan, waxaan ku soo koobnay karaa faa'iidooyinka qalabka sida. Tani isticmaalka awoodda yar yahay hab guurto ah, kharash yar ee wax soo saarka (gaar ahaan ka fiirsaneysa xalinta sare CMOSka-furta). Laakiin faa'iido ugu muhiimsan waa awood u leh inay bixiso diyaar signal digital, taas oo aan u baahnayn beddelaad dheeraad ah.

Isticmaalka CMOSka-technology ee technology computer

user kasta oo qalab computer casri ah maalin kasta hor leh qalab sida a web-camera sida. Laakiin dhowr ogahay in ay ku salaysan waa on mabda'a CMOSka-technology. Web-camera waxaa loo isticmaalaa sida qalab functional shaqsiga, iyo gundhig tusaale ahaan in laptops. aaladaha noocan oo kale ah waxaa loogu talagalay in la codsiyada multimedia shebekadaha shaqeeyaan. Halabuurka ee wax soo saarka ayaa sheegay in ka mid ah: soo diyaariyeen a gashto, kaarka video qabashada ah, filter ah indhaha, unit image riixo ah, processor a, xasuusta flash, web-server, iyo interface network. Matrix ayaa waxaa aasaas u ah fiidiyo ama fotoappatara. Maxaa yeelay, tayada image ee lagu kala qaado waxay ku xirnaan doontaa xalinta ka mid ah qalabka. Halbeegga Tani waxay badanaa in kamaradaha web waa waa in kala duwan oo ka soo 0.1 ilaa 2 megapixels. Si kastaba ha ahaatee, in wax soo saarka ugu badan waa 0.3 megapixels. Arrin kale oo la go'aaminayo webcam qabanayo format jir. The ugu caansan waa furta oo CMOSka 1/4. Waxaa jira qaabab kale, laakiin waxay ka yar tahay wax caadi ah (tusaale ahaan, 1/3, 1/2 ama 2/3 inch ah).
