Raws li tau ua haujlwm cams tsis tu ncua kev nyab xeeb tsis tu ncua cov ntaubntawv povthawj, kev tswj xyuas chaw cia ntawm nco phaib ua ib qho tseem ceeb heev. Ob lub thev naus laus zis tseem ceeb - cov ntxig kaw thiab lub sijhawm sau ntawv - Ua si qhov tseem ceeb ntawm cov tshuab khaws cia ntev thiab kev txo qis kev noj haus. To taub yuav ua li cas lawv cov haujlwm qhia yog vim li cas lawv yog cov tseem ceeb ntawm kev ua haujlwm Cam ua haujlwm.
Loop kaw: Kev Ua Ntej Tsis Tau Ua Ntej
Loop kaw yog qhov tseem ceeb ua haujlwm hom rau cov cams ntau dua. Nws ua haujlwm los ntawm:
· Sib cais cia:Daim npav nco tau kho raws li cov lus luv luv, tsau-duration video ntu ntu (piv txwv li, 1, 3, lossis 5 feeb txhua).
Cov ntaub ntawv kaw cia:Lub koob yees duab cov ntaub ntawv video, sau ib ntu tom qab lwm tus.
Tsis siv neeg sau cia:Thaum lub cim xeeb daim npav yog tag nrho, cov laus tshaj plaws teev ntu yog cia li muab tshem tawm.
Pem teb tsis ntev:Cov ntaub ntawv tshiab uas tau sib sau ua ke dhau cov ntaub ntawv qub tshaj plaws, tsim lub voj nrib pleb.
Yuav ua li cas Ntxoo Cov Ntawv Teev Tseg Qhov Chaw:
· Txwv tsis pub daim ntawv foos uas tsis yog:Yog tsis muaj lub voj kaw, lub koob yees duab yuav tsuas tso kaw ib zaug daim npav puv, tawm ntawm cov neeg tsav tsheb tsis muaj kev tiv thaiv. Voj cov ntaub ntawv ua kom ntseeg tau cov ntaubntawv tsis pub dhau los ntawm kev tso chaw tsis tu ncua.
· Nco txog cov xwm txheej tsis ntev los no:Nws inherently ua ntej tshaj plaws cov footage tshiab tshaj plaws. Cov duab loj dua, ua rau tsis tshua muaj qhov tseem ceeb, tsis tu ncua rov ua dua tshiab, ua kom pom qhov chaw ib txwm muaj rau cov ntaub ntawv tshiab.
Kev tiv thaiv:Qhov tseem ceeb, ntu ntu manually cawm los ntawm tus neeg siv lossis cia li xauv cov kev xav tau (g-sensor) cov xwm txheej feem ntau yog tiv thaiv los ntawm kev siv cov pov thawj tseem ceeb.
Lub Sij Hawm Teev: ntes cov xuab moos hauv feeb
Lub sijhawm-lapse kaw cia (lossis chaw nres tsheb hom sij hawm-Lapse) yog hom tshwj xeeb, feem ntau siv rau kev ntsuas nres nres tsheb. Nws ua haujlwm los ntawm:
Txo txo cov kab ntawv ntes:Hloov chaw sau cov yeeb yaj kiab txuas ntxiv ntawm tus qauv txheem ib ob), lub koob yees duab yuav ntes tau ntau dua (piv txwv li 1, lossis 5 vib nas this).
Cov cuab yeej ua si playback:Cov neeg no tau muab sau ua cov ntawv video. Thaum ua si rov qab ntawm tus qauv txheem tus nqi, lub sijhawm tshwm sim tau spramatically sped li-teev ntawm cov txheej xwm tiag tiag yog condensed mus rau feeb.
Cas lub sij hawm-lapse kaw chaw seem (ua kom zoo):
Cov ntaub ntawv txo qis:Txais tsuas yog 1 thav duab txhua ob peb feeb, hloov ntawm 30 thav duab txhua thib ob, txo cov ntaub ntawv nyoos ntawm 30, 60, 150, lossis ntau dua. Nov yog thawj qhov chaw txuag hluav taws xob.
· Txuas ntxiv:Qhov kev ua tau zoo no tso cai rau lub tsheb khiav ceev ceev rau lub sijhawm nres tsheb uas siv ib feem ntawm cov chaw khaws cia ntev ntev.
Kev tshwm sim pib:Thaum zoo cov lus qhia nthuav tawm yog ploj, lub sijhawm-lapse zoo qhia tau cov txheej txheem ntawm lub tsheb (piv txwv li ib tug neeg mus ncig, ib lub rooj zaum tawm ntawm qhov chaw nres tsheb) tshaj lub sijhawm nres tsheb) dua lub sijhawm nres tsheb.
Lub sib xyaw ua ke: kev siv cov khoom siv cia
Ob lub voj kaw thiab lub sijhawm-lapse khaws cov kev sib tw ntawm nco nco lub cim xeeb muaj peev xwm:
Thauj kaw:Ua kom ntseeg tau cov haujlwm txuas ntxiv los ntawm kev txawj ntse uas tsis tau tshaj tawm tsis yog tus ntiv tes tseem ceeb, tiv thaiv daim npav los ntawm kev sau thiab nres. Nws tswj qhov chaw nyob hauv cov qauv sau tseg hom.
·-Lapse kaw:Radically txo cov ntaub ntawv hneev taw ntawm qhov kev ntes ntawm kev ntes thaum lub sijhawm tshwj xeeb (xws li chaw nres tsheb), tso cai rau cov npav me me. Nws tsim qhov chaw ua haujlwm los ntawm kev hloov pauv hauv txoj kev kaw tseg.
Vim li cas qhov teeb meem no rau cov tsav tsheb:
· Unaintrupt kev tiv thaiv:Loop ntaubeering lav lub koob yees duab yog ib txwm sau cov kev sib tw tshaj tawm tshiab tsis muaj kev cuam tshuam ntawm kev tiv thaiv phau ntawv.
· Kev nres tsheb ntev hauv kev nres tsheb:Lub sijhawm-Lapse hom ua rau cov neeg pheej yig, ntev ntev cov ntaub ntawv rau kev ntaus-thiab-khiav lossis kev sib tw uas tej zaum yuav tshwm sim tom qab tawm hauv lub tsheb.
Per -kas ua haujlwm zoo:Los ntawm kev kho kom zoo, ob qho thev naus laus zis txo cov zaus ntawm kev xav tau kom pom tseeb daim npav lossis yuav khoom loj heev (thiab kim) high-endence nco phaib.
Vim li cas khaws pov tseg:Cov ntaub ntawv muaj kev tiv thaiv nyob hauv cov ntawv teev cov ntaub ntawv thiab cov txheej txheem cej luam tau muab los ntawm lub sijhawm-lapse txhim kho tus tsav tsheb muaj peev xwm ntes thiab khaws cov duab duab zoo nkauj.
Ntse Technology rau Kev Thaj Yeeb Ntawm Lub Siab
Cov ntaube teev thiab cov sijhawm-kaw cov ntaubntawv tsis yog tshwj xeeb; Lawv yog cov kev txawj ntse ua cov kev daws teeb meem rau cov kev txwv ntawm kev tsoo cam cia. Los ntawm kev nkag siab tias cov qauv no ua haujlwm li cas - cov tsav tsheb tuaj yeem txaus siab rau lawv cov cams ua rau muaj kev tiv thaiv kev tswj hwm kev tswj hwm kev cia. Cov thev naus laus zis yog qhov tseem ceeb rau kev ntseeg siab, ntev-ntev khiav nrawm cam kev ua tau zoo.
