Kuyini isithwebuli

ikhompyutha Abaningi amadivayisi neuropathy okwamanje asetshenziswa ekhaya, kuze kube muva nje ingatholakala kuphela emahhovisi ezinkampani ezinkulu. Yilokho okwenzeka kuma-Enani ikhompyutha. Abakhiqizi washeshe wabona ukuthi lokhu niche market likhululekile, futhi sakwazi ukuqala ukukhiqizwa idivayisi kwesabelomali ekilasini, okuyinto imisebenzi ngokugcwele izidingo kwe-avareji ikhaya umsebenzisi.

Naphezu kweqiniso lokuthi ezitolo computer ukunikela anhlobonhlobo lezi amadivaysi, ngokuvamile ngesikhathi isivakashi, nawu umbuzo, uyini Enani. Lena ejwayelekile, kubangelwa ukuphishekela ulwazi ngokwemvelo. Namuhla sibheka ukuthi yini isithwebuli futhi yini okumelwe siyibheke lapho uthenga.

Scanner - kule divayisi opto obuzisebenzela yokuguqula Imininingwane isithombe ku ifomu digital, okuyinto ongasebenza ngayo uhlelo kukhompyutha. Nansi incazelo elula. Nokho, ukuze ukuqonde ngokwengeziwe lokho isithwebuli, kudingeka utadishe isakhiwo layo langaphakathi. Lokhu kuzokhulisa abasebenzi hhayi kuphela isizinda solwazi, kodwa futhi ikuvumela ukuthi ukhethe imodeli esifanelana.

Ubude isithwebuli yokusebenza Isimiso ilula: into ukuskenwa ukuqondisa imisebe ukukhanya kancane kubonakala ku izakhi svetoregistriruyuschie. Ngenxa amazinga ehlukene kuveza (isib, umbala omnyama ibonisa sibi kakhulu kunalokho okuboniswa omhlophe) logic iyunithi yakha "ukuphrinta" digital into isikeni. Lokhu ukucaciseleka ivumela ukuphendula ngokunabile umbuzo yini isithwebuli, ngoba ukuskena, kuvela, ungakwazi ngisho izinto besiyoba sikhulu, hhayi nje umbhalo ephepheni, njengoba abaningi becabanga kanjalo. Kodwa, noma kunjalo, kuyaqondakala okwandile kudivayisi ezikhethekile kakhulu yakhelwe ukusebenza umbhalo nezithombe. Naphezu isimiso esifanayo wokusebenza, kunezinhlobo ezahlukene scanner.

Iningi ephansi ekupheleni model kumadivayisi tablet. Ngo kubo ephepheni camera nge Imininingwane sokuqhafaza ubekwe ewindini esobala (ingilazi, plastic) futhi idivayisi yayicindezele phezulu ikhava opaque. Eceleni ishidi guided ugongolo ukukhanya kanye kubonakala lithunjwa. I element eyinhloko isithwebuli --matrix. Kunezinhlobo ezimbili izinhlobonhlobo ke: CIS futhi be-CCD. Endabeni matrix of uhlobo lokuqala ngaphansi ingilazi, okuyinto ibekwe phezu ishidi, ukuthutha kuyinto LED multi-umzila photocells. Yena kancane ezinwabuzelayo ishidi, kuhlanganise LED ujike umugqa obomvu, oluhlaza okwesibhakabhaka, imibala eluhlaza (ezidingekayo ukuze kwakhiwe isithombe umbala).

onobuhle ezinjalo eziphansi nokwethembeka-superior (lutho ikhefu) can ke ukonga isithakazelo abathengi abafuna isixazululo ukuskena namakhasi umbhalo emhlophe. Ngakho sikhumbule ukuthi ijubane ukuskena kancane, kudinga clamping Friend ishidi ku ingilazi, le mediocre izinga izithombe.

Ngo onobuhle be-CCD-matrix diodes akuzona phezu kwekalishi, futhi isibani ukukhanya. Ukukhanya kubonakala eqoqwe uhlelo izibuko ngokugxila, ukuthola umfanekiso umbala sehlukaniswe tincenye bohlu ishuthiwe futhi photocells. Le isixazululo bavunyelwe ukuthola izithombe egqamile futhi acacile eMhlanganweni ekhishwa, kuyilapho uvalwe ephethe ingilazi kungadingeki, njengoba umfutho ukukhanya yanele ukuba unqobe ibanga elifushane. isivinini Icubungula futhi uye kunyuke. Singasho ukuthi namuhla ke yisisombululo kuhle. Ububi kuyinto ukuvinjelwa isibani ukuphila (ngesikhathi ke kuyomelwe bashintshe, njengoba kuqhathaniswa diodes ukukhanya-likhipha) kanye nesidingo sangaphandle ugesi.

Izikena libhekene ukujula ekhishwa (okufanayo 24, 32, 48 izingcezu) kanye nesinqumo. On the izingcezu umbala kumele hhayi kuphela ukugeleza izithombe, kodwa futhi umsindo matrix ngokwayo, ngakho kulapho ngcono. Ngakolunye uhlangothi, akufanele kube ngoba indlu ukuxosha amalulwane - iphrinta ukuthi okukhiphayo isithombe okuskeniwe akakwazi ukubonisa 48-bit ngokwenyama. Ukulungiswa icaciswe njengo-XXX: YYY, lapho «XXX» - amachashazi, futhi «YYY» - izinyathelo ukuthutha.
