Ngoku, abantu abaninzi bafuna ukwazi ukuba yeyiphi isiphumo esingcono phakathi kweskena kunyeikhamera yoxwebhu.Phambi kokuba siphendule lo mbuzo, makhe sithethe ngemisebenzi ephambili yezi zimbini.Iskena sisixhobo esidibeneyo se-optoelectronic esavela kwi-1980s, kwaye umsebenzi wayo oyintloko kukuqonda i-electronization yamaxwebhu ephepha.Ekuqaleni kokuzalwa kwekhamera yoxwebhu, umsebenzi ophambili kukwenza amaxwebhu ephepha nge-elektroniki.Umahluko kuphela phakathi kweeskena ngumgaqo osebenzayo.Ezi zixhobo zimbini zijongana neemfuno ezifanayo, abathengi abaninzi bafuna ukuthelekisa kwaye babone ukuba yeyiphi isixhobo esinesiphumo esingcono.Umahluko omkhulu phakathi kwekhamera ephezulu kunye neentlobo ezahlukeneyo zeskena azikho kangako umphumo, njengoko imeko yesicelo yahlukile.
Iimpawu eziphambili zeikhamera yoxwebhuzezi: amaxwebhu askeniweyo akafuni phepha, akukho nkunkuma yamaphepha, afanele iofisi engenamaphepha.Isantya sokuskena sesixhobo sokubetha esiphakamileyo sikhawuleza, ngelixa iskena semveli sinzima ngakumbi xa uskena uxwebhu, kufuneka uphakamise isiciko ukuguqula iphepha, kwaye isixhobo sokubetha okuphezulu sinokuskena ngokuthe ngqo iphepha.Iskena semveli sinzima ngakumbi xa uskena amaxwebhu.I-scanner ye-Flatbed ngumthombo wokukhanya ovaliweyo, ongachatshazelwa kukukhanya okunamandla, ukuskena umfanekiso awuyi kutshintsha, ngokusisiseko unokufikelela kubukhulu be-1: 1, ukubuyisela umbala ophezulu, umfanekiso ocacileyo.Ilungele ukuskena imizobo yemibala, imifanekiso, iifoto.
Umsebenzi ophambili we-scanner kukuskena, kodwa ukuskena nje ukuthelekisa, iskena singcono kunesixhobo sokudubula okuphezulu, isisombululo se-scanner optical sinokufikelela ngokulula kwi-600dpi kwaye isisombululo siphezulu kakhulu, sifanelekile kwizicelo zokuskena ezichanekileyo. Isetyenziselwa ukwenza idijithali idatha entsonkothileyo kunye nokuqondwa kombhalo we-OCR, iikhamera yoxwebhuIsebenza kakhulu kuneskena, kodwa ukuba ufuna nje isiphumo sokuskena esichanekileyo, iskena singcono.
