Ama-scanner wezithombe angaba lula noma alula kakhulu-ukhetha
Ungacabanga ukuthi uma nje amakhemikhali edijithali futhi, okubaluleke nakakhulu, ama-scanner wesithombe, ayekade eseduze, cishe zonke izithombe emhlabeni kufanele zivele zilungiswe. Maye, ngokusobala, asisafiki ngisho, noma mhlawumbe amakhophi amakhophi amasha akhiqizwa nsuku zonke-mhlawumbe kokubili. Kunoma yikuphi, iphuzu yilapho, njengoba nje isidingo samaphrinta wezithombe siyaqhubeka, kunjalo nesidingo sokuskena izithombe. Kodwa-ke, akuwona wonke ama-scanner wesithombe ofanayo, futhi kuncike kulokho ohlela ukuskena, ikhwalithi yeskena edingekayo, nokuthi uhlela kaningi kangakanani ukuskena izithombe, ukucacisa indlela oyinkimbinkimbi yomshini oyidingayo.
Mayelana ne-Photo Scanners
I-scanner yezithombe ezinhle kunazo zonke kuyi-scanner ye-drum, kodwa kuphela amahhovisi okusebenzela izithombe ezikhethekile angakwazi ukukhokhela labo. Okulandelayo okungcono kunamaphiksethi aphezulu okuxazulula izixazululo, njenge-Epson's $ 1,000 (noma ngaphezulu) i- Perfection V850 Pro Photo Scanner .

Uma ufuna ukusebenzisa izikrini zakho zezithombe, ukukhanya, ama-slide, nokunye okunjalo ekuphrintiweni kwezakhiwo noma ezinye izinhlelo zokusebenza ezidinga izinqumo eziphezulu, uzodinga ukuskena ezinqumweni eziphakeme kakhulu, noma amachashazi ngamasentimitha (dpi), ukuze bakwazi ukukhuliswa ngaphandle kokunciphisa ikhwalithi yesithombe. Ama-scanners e-photo amahle, njenge-Epson model ebalwe ngenhla, isibonelo, angakwazi ukuskena ngokuphezulu njengama-6,400dpi nangaphezulu.
Isibonelo, ukuguqula isilayidi esithombeni esingu-8x10-intshi, udinga ukuskena ku-2,000dpi noma ngaphezulu.
Futhi amaphikseli ngamasentimitha angu-intshi (i-ppi) yesithombe enezilinganiso zomzimba ezingu-8x10 amayintshi ngu-1,800x3,000, ku-600dpi ..
Ukuthenga Okuzungezile
Linda umzuzu nje. Ngakho usuvele ubheke nxazonke futhi uthola isithwebuli se-flatbed njengalezo engichazwe esigabeni esandulele-kuphela i-$ 100 kuphela. It is scans at 9,600dpi, ine-48-bit bit color depth ukujula, futhi iza nazo zonke ukuhlela izithombe nezinye software edingekayo ukuze uthinte-up bese ulondoloze izithombe oskenayo, kanye software optical uhlamvu ukuqashelwa (OCR) , kanye nesofthiwe yokuqoqa amadokhumenti.
Okuningi, akunjalo? Yebo, yebo, uma konke okwenzayo kuskena izithombe ze-Facebook nezinye izingosi zokuxhumana, lokhu kusetha kuhle. Kodwa khumbula ukuthi okuningi kokuxazululwa kombala nokukhiqizwa kombala okwenziwe kumodeli angabizi kakhulu yimiphumela yokubamba iqhaza kanye nezinye izinhlelo zokusebenza zesofthiwe, noma iningi lentuthu nezibuko, kanti izinqumo eziphezulu kanye nobukhulu bombala obanjwe yi-$ 1,000-scanner (noma ngaphezulu) empeleni kuthathwa futhi ilandwe ngamalensi ngaphakathi kwesithwebuli. Ngamanye amazwi, uthola ukukhiqiza okuningiliziwe nge-dot-per-dot, kunesithombe lapho isithwebuli (nesofthiwe esibonakalayo esibonakalayo) inxephezela ukungabi khona kwezinga eliphezulu, izinzwa eziphezulu.
Ukuthatha i-Plunge
Ngakho-ke isiphi isithwebuli sithombe esizokusebenzela? Ngokweqiniso, uma iningi lezithombe zakho lizobonakala kuWebhu, mhlawumbe lilondolozwe, noma mhlawumbe lilondolozwe kukhathalogi yakho yedijithali noma kudivayisi yakho ye-computing noma isayithi lakho eliyintandokazi yamafu, isithwebuli se-$ 100 sizosebenza kahle kuwe. Abachwepheshe kuphela abahlose ukuphrinta noma ukusebenzisa enye inguqulo ephezulu yokulungisa izithombe kwezinye izindawo, badinga ukwelashwa okwenziwa isithwebuli esiphezulu sezithombe. Futhi yebo, ngezinye izikhathi, kuye ngokuthi isicelo sakho, leso sithwebuli esingaphakathi kwephrinti yakho ye-multifunction iyokwenza kahle-ngezinye izikhathi.
