Taw qhia
Cov koob yees duab digital tau tshwm sim hauv cov khw muag khoom noj khoom haus li ntawm rau xyoo. Los ntawm thawj ob peb hom xws li Apple, Sony, thiab Kodak (tsis suav cov koob yees duab digital), kuv ntseeg tias muaj ntau tshaj ib puas hom (tus sau tsis muaj ntaub ntawv xeem). Qee lub npe yeej coj txawv txawv rau tus sau. Yuav luag txhua theem tswv yim ua lag luam tau tso digital koob yees duab, thiab txawm tias lub npe nrov Factories Hasselblad thiab Rollei kuj tau tso digital koob yees duab! Tsis yog cov koob yees duab ntawm cov koob yees duab ua cov digital koob yees duab xwb, tab sis kuj muaj cov tshuab computer xws li IBM thiab HP.
