I. Magnification Levels thiab Flexibility:
Traditional magnifiers feem ntau muab lub zog ruaj khov, xws li 2x, 5x, lossis 10x. Electronic magnifiers, ntawm qhov tod tes, muab cov qib magnification adjustable. Cov neeg siv feem ntau tuaj yeem xaiv lawv qhov kev xav tau ntawm kev nthuav dav, uas tso cai rau kev hloov pauv ntau dua hauv kev saib cov khoom sib txawv lossis cov ntawv ntawm ntau qhov sib txawv. Qhov kev hloov pauv no ua rau cov khoom siv hluav taws xob tsim nyog rau ntau txoj haujlwm thiab cov tib neeg uas muaj qhov sib txawv ntawm qhov xav tau.
II. Zaub Technology thiab Image Enhancement:
Cov khoom lag luam niaj hnub siv cov lo ntsiab muag los nthuav cov khoom uas tau pom, thaum cov khoom siv hluav taws xob siv cov koob yees duab thiab cov ntxaij vab tshaus. Lub koob yees duab ntes cov duab ntawm cov khoom, uas tom qab ntawd tso tawm ntawm qhov screen. Kev siv cov thev naus laus zis tso tawm qhib qhov muaj peev xwm rau cov duab txhim kho cov yam ntxwv tsis pom nyob rau hauv ib txwm siv magnifiers.
Electronic magnifiers feem ntau muaj cov yam ntxwv xws li kho qhov ci, qhov sib piv, thiab xim hom. Cov kev xaiv no tso cai rau cov neeg siv los kho cov duab tso tawm raws li lawv qhov kev nyiam pom thiab ua kom pom kev pom zoo rau cov khoom sib txawv lossis cov ntaub ntawv nyeem. Qee lub tshuab hluav taws xob hluav taws xob txawm muab lwm hom xim, xws li greyscale, inverted xim, los yog customizable xim ob peb ua ke, los hais txog tej yam tsis pom kev zoo li xim dig muag lossis tsis pom kev.
III. Ntxiv nta thiab kev ua haujlwm:
Electronic magnifiers feem ntau tuaj nruab nrog cov yam ntxwv ntxiv uas txhim kho tag nrho cov neeg siv kev paub thiab kev siv tau. Cov yam ntxwv no tuaj yeem sib txawv nyob ntawm tus qauv tshwj xeeb thiab cov chaw tsim khoom tab sis kuj muaj xws li:
a. Freeze Ncej: Qhov no tso cai rau cov neeg siv los ntes thiab khov cov duab tso rau ntawm qhov screen. Nws yog qhov tshwj xeeb tshaj yog thaum nyeem lossis tshuaj xyuas cov ntsiab lus uas xav tau cov duab khov kho.
b. Duab Cia thiab Rov Qab Rov Qab: Qee cov khoom siv hluav taws xob muaj lub cim xeeb los yog lub peev xwm khaws cia uas tso cai rau cov neeg siv txuag thiab nco qab cov duab uas tau ntes yav dhau los. Cov yam ntxwv no muaj txiaj ntsig zoo rau kev xa tawm lossis tshuaj xyuas cov ntaub ntawv tom qab lub sijhawm.
c. Cov ntawv nyeem-rau-hais lus: Ntau lub tshuab hluav taws xob hauv hluav taws xob suav nrog Optical Character Recognition (OCR) thev naus laus zis, ua rau lawv hloov cov ntawv luam tawm mus rau kev hais lus. Qhov kev ua haujlwm no tseem ceeb tshwj xeeb tshaj yog rau cov tib neeg uas muaj qhov tsis pom kev uas yuav nyiam mloog cov ntawv nyeem ntau dua li nyeem nws.
d. Adjustable Viewing Modes: Electronic magnifiers feem ntau muaj ntau hom kev saib, suav nrog cov xim puv, qhov sib txawv siab, thiab cov xim sib txawv. Cov qauv no ua raws li qhov xav tau ntawm qhov muag sib txawv thiab tuaj yeem txhim kho kev nyeem ntawv thiab kev nplij siab.
e. Kev sib txuas: Qee cov khoom siv hluav taws xob muaj cov kev xaiv sib txuas, xws li USB chaw nres nkoj lossis lub peev xwm wireless, tso cai rau cov neeg siv hloov cov duab lossis txuas rau cov khoom siv sab nraud xws li khoos phis tawj lossis TV rau kev pom loj dua.
IV. Portability thiab Loj:
Ib txwm siv magnifiers feem ntau yog tuav los yog mounted ntawm cov khoom muag. Txawm hais tias qee qhov hluav taws xob magnifiers kuj tuaj yeem nqa tau yooj yim, lawv feem ntau yog compact dua thiab hnyav dua piv rau cov khoom siv magnifiers. Electronic magnifiers feem ntau tuaj nyob rau hauv daim ntawv ntawm cov khoom siv tes nrog cov ntxaij vab tshaus foldable los yog portable units nrog built-in cov ntxaij vab tshaus. Qhov loj me me thiab txav tau yooj yim ua rau cov khoom siv hluav taws xob tau yooj yim siv rau ntau qhov chaw, xws li hauv tsev, hauv tsev kawm ntawv, lossis thaum mus ncig.
V. Nqi:
Cov khoom siv hluav taws xob zoo li yuav kim dua li cov khoom lag luam niaj hnub vim lawv cov thev naus laus zis siab, cov yam ntxwv ntxiv, thiab cov peev xwm tso saib. Tus nqi tuaj yeem sib txawv nyob ntawm tus qauv thiab hom, nrog rau ntau yam ntawm cov yam ntxwv thiab kev ua haujlwm muaj.
