Analog koob yees duab (CVBS, CCTV)

Nyob rau hauv lub tshav pob ntawm kev ruaj ntseg video soj ntsuam, analog thiab digital, raws li zoo raws li lub network yog nrog rau ib leeg.Lub koob yees duab kev ruaj ntseg thaum ntxov yog analog (Analog), lub npe hu ua analog, txhais tau hais tias lawv simulate lub cev kom muaj nuj nqis uas sawv cev rau lub suab, cov ntaub ntawv duab, lub teeb liab ntawm lub hom phiaj uas tau yees duab yog hloov dua siab tshiab rau hauv cov teeb liab hluav taws xob, lub waveform ntawm lub analog. teeb liab simulates qhov kev hloov ntawm cov ntaub ntawv.Qhov sib txawv ntawm qhov ci ntawm cov khoom uas tau yees duab sib haum rau qhov sib txawv ntawm qhov ci ci, qhov tam sim no hauv lub koob yees duab lub raj hluav taws xob yuav hloov raws li.Analog teeb liab yog siv qhov kev hloov pauv tam sim no los sawv cev lossis simulate cov duab ntes, sau lawv cov yam ntxwv kho qhov muag, thiab tom qab ntawd los ntawm kev hloov kho thiab demodulation, lub teeb liab yuav raug xa mus rau lub receiver, tso tawm rau ntawm qhov screen, rov qab mus rau qhov qub optical duab. .

Cov koob yees duab analog tau muab faib ua analog SD koob yees duab thiab analog HD koob yees duab raws li lawv cov kev daws teeb meem.Analog koob yees duab feem ntau siv BNC connectors ua video tso zis connector.

CVBS Camera

Analog SD lub koob yees duab tseem hu ua CVBS lub koob yees duab, lub npe hu ua CVBS hais txog Composite Video Broadcast Signal, uas yog, sib xyaw synchronous video tshaj tawm cov teeb liab.Nws xa cov ntaub ntawv nyob rau hauv ib tug analog waveform.Cov yees duab sib xyaw muaj chromatic aberration (xim thiab saturation) thiab luminance (brightness) cov ntaub ntawv thiab synchronizes lawv nyob rau hauv ib tug fading mem tes, kis nrog tib lub teeb liab.

CVBS cov koob yees duab siv TVLine (kab TV, kab TV) los ntsuas lub peev xwm los daws cov duab.Thaum ntxov CVBS analog koob yees duab tuaj yeem nkag tau los ntawm BNC lub taub hau analog saib ncaj qha tso saib cov duab yeeb yaj kiab, thiab qhov ntse ntawm cov duab ntawm no analog saib yog qhov tseeb ntawm cov ntsiab lus ntawm cov kab dub thiab dawb kab rov tav uas nyob ib sab.Yog li lub koob yees duab analog pom meej ntawm chav ntsuas ntsuas kuj tseem hu ua TV Line, tseem hu ua TV Line (uas yog, TVLine), qee zaum kuj hu ua qhov pom tseeb ntawm qhov kev daws teeb meem.Analog lub koob yees duab daws teeb meem feem ntau yog kuaj los ntawm ISO12233 Daim Ntawv Qhia (Daim Ntawv Qhia), thiab nrog kev pab los ntawm cov cuab yeej thib peb, xws li ImaTest, HYRes, iSeetest thiab lwm yam software los nyeem cov nqi tiag tiag.Piv txwv li, 650 kab txhais tau hais tias lub koob yees duab no tuaj yeem paub qhov txawv ntawm cov kab cim ntawm daim ntawv xeem daim npav ze ntawm tus nqi ntawm 650.

CVBS lub koob yees duab cov kev pab cuam muaj ntau heev, lub hauv paus ntawm txhua qhov kev pab cuam yog DSP thiab sensor ob feem.Thaum Ntxov DSP kev pab cuam feem ntau yog Sony's SS-1 (2163), SS-11 (3141/2), SS-11X (4103), SS-HQ1 (3172), SS-2, Effio-E (SS4), Effio-P, Effio-A, Effio-V, thiab lwm yam .. Panasonic rau D5 feem ntau yog D4, D5 MN673276, Kaus Lim Kauslim Samsung, NEXTCHIP processor, Taiwan A-NOVA ADP series, thiab lwm yam.. Thiab sesnor tseem yog rau Sony, Panasonic, Samsung feem ntau.Qhov sib txawv ntawm DSP thiab sensor ua ke saum toj no tuaj yeem tsim los rau cov kev daws teeb meem sib txawv.

Effio series dhau los ua Sony hauv analog SD lub koob yees duab saib lub sijhawm kawg zaj nkauj."Effio" yog "Txhim kho cov yam ntxwv thiab cov duab zoo" (Enhanced Features and Fine Image Processor) acronym.Qhov siab tshaj plaws daws teeb meem ntawm Effio series yog nyob ib ncig ntawm 750 kab - 800 kab.Qhov no yog qhov kev daws teeb meem siab tshaj plaws uas tau ua tiav los ntawm analog SD lub koob yees duab.Lub koob yees duab Effio ib txwm muaj qhov zoo pixel suav ntawm 976 ( kab rov tav) x 582 ( ntsug), yog li nws tseem hu ua 960H lub koob yees duab (zoo pixels ntau dua 960 nyob rau hauv kab rov tav kev taw qhia).

Lub Effio series tau pib nyob ib ncig ntawm 2009, thiab cov tshuaj Effio-P tau qhia hauv 2012. Tom qab ntawd Sony yuav tau tsom mus rau kev tshawb fawb thiab kev loj hlob ntawm CMOS, analog SD koob yees duab kuj maj mam los txog.

Analog HD koob yees duab

Sony tso tseg CCD, lub hom phiaj tseem ceeb yuav hloov mus rau CMOS yog vim tib yam kev daws teeb meem, tus nqi ntawm CMOS qis dua, thiab qhov kev daws teeb meem siab dua, qhov sib txawv ntawm tus nqi ntau dua, uas txhais tau tias CCD tsis haum rau kev daws teeb meem siab. koob yees duab kev ruaj ntseg.Lub koob yees duab kev ruaj ntseg rau HD, thawj yam uas yuav tsum tau muab tshem tawm yog CCD sensor.
