Qhov sib txawv ntawm cov kev daws teeb meem txawv koob yees duab: 4K vs 1080p vs 720p

Thaum xaiv lub koob yees duab zais, daws teeb meem yog ib qho tseem ceeb tshaj plaws los txiav txim siab. Qhov kev pom tseeb ntawm kev txiav txim siab feet tau txiav txim siab zoo li cas los tau cov ntsiab lus ntawm lub ntsej muag, daim ntawv tso cai daim hlau, thiab hloov maj mam txav. Seb puas yog kev ruaj ntseg hauv tsev, kev saib xyuas haujlwm, lossis cov phiaj xwm kev tshawb nrhiav, lub koob yees duab daws teeb meem ntau dua uas tsis ploj vim yog pixelation lossis cov duab tsis zoo.

Nrog thev naus laus zis txhim kho, cov koob yees duab soj ntsuam cov koob yees duab tam sim no, suav nrog 720p (HDS HD), thiab 4K (ultra siab ntsiab lus). Txhua tus muaj nws cov peev xwm, thiab nkag siab txog lawv qhov sib txawv yuav pab koj xaiv qhov kev xaiv zoo tshaj plaws raws li koj cov kev xav tau tshwj xeeb. Raws li tus kws tshaj lijHD zais npe Chaw tsim tshuaj paus, Kuv yuav tsom rau qhov txawv ntawm 4k vs 1080p vs 720p daws teeb meem hauv tsab xov xwm no

Lub koob yees duab daws teeb meem yog dab tsi?

Kev txhais thiab tseem ceeb ntawm kev daws teeb meem

Lub koob yees duab daws teeb meem yog hais txog tus naj npawb ntawm cov pixels uas ua rau cov duab lossis yees duab. Ib qho siab dua kev daws tau txhais tau tias ntau cov pixels, ua rau ci ci thiab muaj cov ncauj lus kom ntxaws. Kev daws teeb meem feem ntau yog sawv cev raws li dav × qhov siab (piv txwv li 1920 × 1080p), thiab tag nrho cov pixel suav txiav txim siab ntau npaum li cas cov duab khaws cia.

Lub koob yees duab 4K muab kwv yees li plaub zaug nthuav dav ntawm 1080p, thaum 1080p yog ob zaug li 720p. Txawm li cas los xij, daws teeb meem ib leeg tsis txiav txim siab video zoo. Lwm yam, xws li sensor thev naus laus zis, lens zoo, thiab compression algorithms, ua lub luag haujlwm tseem ceeb hauv kev ua tau zoo ntawm lub koob yees duab zais.

Cov ntsiab lus tseem ceeb cuam tshuam rau kev ua yeeb yaj kiab zoo

Cov Duab Sensor Tshuab

Cov duab sensor yog cov tseem ceeb tivthaiv ntawm ib lub koob yees duab, hloov lub teeb ci rau hauv cov cim hluav taws xob los tsim cov duab. Ob hom ntawm cov hom sensor feem ntau yog Cmos (miv kev xaiv hlau-oxide-semiconductor) thiab CCD (them nyiaj rau cov kev soj ntsuam niaj hnub, kev ua kom zoo dua qub.

Ntawm Shenzhen Hyteech Technology Co., Ltd, suav txog CMOS CAPO Sensors, suav nrog IMX477, Imx586, thiab OV48C, uas yog cov kev ua kom muaj cov ntsiab lus niaj hnub no. Cov sensors txhim kho kev daws teeb meem, txhawb nqa 4K cov video kaw thiab muab cov xim txo qis. Txawm nyob hauv ib puag ncig qis, peb cov koob yees duab tswj cov teeb liab siab-rau-suab nrov sib piv, ua kom pom tseeb thiab ntxaws ntxaws.

Lens Zoo

Lub koob yees duab daws teeb meem siab tsuas yog zoo li nws lub lens. Hwm cov lo ntsiab muag ntau lub teeb, txo lub glarement, thiab txo lub koob yees duab los ntes cov lus zoo nrog cov ntse thiab meej. Qhov zoo tshaj ntawm lub lens tseem cuam tshuam rau kev tsom mus rau cov khoom nyob deb, uas yog qhov tseem ceeb rau kev txheeb xyuas ntsej muag thiab nyeem cov ntawv nyeem hauv kev soj ntsuam cov duab.

Compression Algorithms (H.265 thiab H.264)

Cov koob yees duab siab dua tsim cov ntawv ntau thiab tsawg, uas tuaj yeem siv chaw cia khoom tseem ceeb thiab bandwidth. Txawm li cas los xij, kev nce qib hauv kev yees duab thev naus laus zis tau hais txog qhov teeb meem no. H.265 (High-eff-eff-eff-eigh-eigh-eigh-eigh-eigh-eigh-effecticicy video coding, HECHC) yog kev txhim kho version ntawm H.264, tso cai rau txog 50% kev ua haujlwm zoo dua. Qhov no txhais tau tias yog 4k koob yees duab siv H.265 tuaj yeem khaws cov video footage nyob rau hauv tib qhov chaw uas 1080p lub koob yees duab yuav xav tau nrog cov laus H.264 compression.

Vim li cas kev daws teeb meem tseem ceeb rau cov koob yees duab uas zais
