Kev Kaw Video Slow-Mo nrog Lub Koob Yees Duab Digital: Technology thiab Kev Muaj Tswv Yim hauv Lub Caij Nyoog Niaj Hnub Nim No
Kev siv tshuab kaw video tau nce qib sai heev nyob rau xyoo tas los no. Ib qho uas tau nrov zuj zus thiab nrhiav tom qab yog kev kaw video qeeb qeeb. Cov thev naus laus zis no tso cai rau peb kom kaw cov sijhawm qeeb qeeb, tsim cov teebmeem zoo nkauj thiab kos duab. Tsab xov xwm no yuav tshawb nrhiav seb cov koob yees duab digital niaj hnub no ua rau kev kaw video qeeb qeeb li cas, cov thev naus laus zis tom qab nws, thiab cov tswv yim muaj tswv yim rau kev siv nws hauv ntau yam kev tsim khoom.
Keeb Kwm Luv Luv ntawm Kev Txav qeeb
Ua ntej peb mus ntxiv, nws yog ib qho pab tau kom kawm me ntsis txog keeb kwm ntawm kev kaw cov yeeb yaj kiab qeeb qeeb. Kev siv cov kev txav qeeb hauv zaj duab xis thiab video tuaj yeem taug qab mus rau thaum ntxov xyoo pua 20th. Ernst Mach, tus kws tshawb fawb Austrian thiab tus kws tshawb fawb, yog ib tus thawj coj hauv kev siv cov txheej txheem qeeb qeeb los tshuaj xyuas kev txav ntawm cov khoom. Tom qab ntawd, Eugène Lauste, tus kws tsim khoom Fabkis, tau tsim thawj lub koob yees duab ceev ceev nyob ib puag ncig xyoo 1912.
Txawm li cas los xij, kev siv cov thev naus laus zis no hauv kev lag luam ua yeeb yaj kiab tsuas yog pib muaj nyob rau nruab nrab xyoo pua 20th.

Algorithm Ua Yeeb Yaj Kiab
Tom qab lub sensor ntes tau daim duab lawm, cov algorithms ua video hauv lub processor duab ua lub luag haujlwm tseem ceeb hauv kev nias thiab teeb tsa cov ntaub ntawv. Cov algorithms no yuav tsum muaj peev xwm ua cov ntaub ntawv sai sai kom tsis txhob muaj kev ncua sijhawm thiab xyuas kom meej tias cov yeeb yaj kiab zoo tshaj plaws tau tsim tawm.
Cov Apps Yees Duab qeeb qeeb uas muaj tswv yim
Cov yeeb yaj kiab qeeb qeeb tsis yog hais txog kev ua kom qeeb qeeb xwb; nws kuj yog hais txog kev qhia txog kev zoo nkauj, cov ntsiab lus, thiab lub zog uas nyuaj rau thaij nrog cov yeeb yaj kiab ib txwm muaj. Nov yog qee qhov kev siv cov yeeb yaj kiab qeeb qeeb uas koj tuaj yeem sim:
Cov Duab Ua Si
Hauv kev tsim cov yeeb yaj kiab lossis suab paj nruag video, cov xwm txheej ua yeeb yam feem ntau raug thaij hauv qeeb qeeb kom ntxiv qhov muaj zog thiab ua yeeb yam. Cov kev txav ceev xws li kev tawg, kev ncaws, lossis kev dhia zoo li meej dua thiab ntxaws dua thaum thaij hauv qeeb qeeb, ua rau cov neeg saib pom zoo dua qhov kev seev cev thiab cov teebmeem tshwj xeeb siv.
Kev thaij duab kis las
Kev ua si nawv yog lwm qhov chaw uas kev kaw suab qeeb qeeb zoo heev. Cov neeg ncaws pob khiav, dhia, lossis ua cov kev txav mus los uas muaj kev txawj ntse heev tuaj yeem raug tshuaj xyuas thiab txaus siab dua los ntawm cov yeeb yaj kiab qeeb qeeb. Slow-mo tso cai rau peb pom tus khau khiav kov txoj kev lossis lub pob tawb ya saum huab cua mus rau lub hoop hauv cov ntsiab lus zoo kawg nkaus.
Cov Ntaub Ntawv Txog Xwm
Lub ntiaj teb no puv npo nrog kev zoo nkauj uas feem ntau tib neeg lub qhov muag tsis pom thaum lub sijhawm ceev ib txwm muaj. Cov yeeb yaj kiab qeeb qeeb tso cai rau peb thaij duab cov sijhawm ntuj tsim xws li noog ya, cov dej poob, lossis cov kab ya hauv txoj kev zoo nkauj heev.
