Lik'hamera tsa Analog (CVBS, CCTV)

Lefapheng la ts'ireletso ea video ea ts'ireletso, analog le digital, hammoho le marang-rang a tsamaisana le tse ling.Lik'hamera tsa ts'ireletso tsa pele ke analog (Analog), eo ho thoeng ke analog, e bolela hore li etsisa palo ea 'mele e emelang molumo, tlhahisoleseling ea setšoantšo, lets'oao le khanyang la sepheo se nkuoang se fetoloa lets'oao la motlakase, waveform ea analog. lets'oao le etsisa phetoho ea litaba.Khanya e fapaneng ea ntho e nkoang foto e lumellana le litekanyetso tse fapaneng tsa khanya, hona joale ka har'a tube ea elektronike ea khamera e tla fetoha ka tsela e nepahetseng.Letšoao la Analog ke ts'ebeliso ea phetoho ena ea hajoale ho emela kapa ho etsisa setšoantšo se hapuoeng, ho rekota litšobotsi tsa bona tsa optical, ebe ka ho feto-fetoha le ho nyenyefatsa, lets'oao le tla fetisetsoa ho moamoheli, le bonts'itsoeng skrineng, le khutlisetsoe setšoantšong sa mantlha sa optical. .

Lik'hamera tse tloaelehileng tsa analog li ka aroloa ka lik'hamera tsa SD tsa analog le li-analog HD lik'hamera ho latela qeto ea tsona.Likh'amera tsa analoge hangata li sebelisa likhokahanyo tsa BNC joalo ka sehokelo sa tlhahiso ea video.

Khamera ea SD ea Analog e boetse e tsejoa e le kh'amera ea CVBS, eo ho thoeng ke CVBS e bua ka Letšoao la Phatlalatso ea Video ea Composite, ke hore, lets'oao la phatlalatso la video le kopaneng.E fetisetsa data ka mokhoa oa analog waveform.Video e kopantsoeng e na le leseli la chromatic aberration (hue le saturation) le leseli (khanya) mme e li hokahanya ka sekhahla se nyamelang, se fetisoang ka lets'oao le ts'oanang.

Lik'hamera tsa CVBS li sebelisa TVLine (mohala oa thelevishene, mohala oa TV) ho lekanya bokhoni ba ho rarolla litšoantšo.Lik'hamera tsa khale tsa analoge tsa CVBS li ka fihlelleha ka "BNC head analog monitor" e bonts'ang litšoantšo tsa video ka kotloloho, 'me ho hlaka ha setšoantšo ho sebono sena sa analoge ha e le hantle ke tekanyo ea lintlha tsa mela e haufi e metšo le e tšoeu.Kahoo ho hlaka ha khamera ea analoge ea tekanyo ea tekanyo e boetse e bitsoa TV Line, e tsejoang hape e le TV Line (ke hore, TVLine), ka linako tse ling e boetse e bitsoa ho hlaka ha qeto.Qeto ea kh'amera ea Analog hangata e lekoa ke ISO12233 Chart Card (Chate), le ka thuso ea lisebelisoa tsa mokha oa boraro, joalo ka ImaTest, HYRes, iSeetest le software e 'ngoe ho bala boleng ba nnete.Mohlala, mela e 650 e bolela hore kh'amera ena e khona ho khetholla ho fihla ho mela e tšoailoeng kareteng ea chate ea liteko haufi le boleng ba 650.

Mananeo a khamera ea CVBS a mangata, motheo oa lenaneo ka leng ke DSP le sensor likarolo tse peli.Lenaneo la pele la DSP haholo-holo 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, joalo-joalo. Panasonic ho D5 haholo-holo D4, D5 MN673276, Korea Samsung, NEXTCHIP processor, Taiwan A-NOVA ADP letoto la lihlooho tse, joalo-joalo .. Le sesnor hape haholo-holo ho Sony, Panasonic, Samsung haholo-holo.Metsoako e kaholimo e fapaneng ea DSP le sensor e ka etsoa bakeng sa tharollo ea lik'hamera tse fapaneng.

Letoto la Effio le fetoha Sony nakong ea kh'amera ea analog ea SD pina ea ho qetela."Effio" ke "Litšobotsi tse Ntlafetseng le Motlakase oa Litšoantšo tse Ntle" (Litšobotsi tse Ntlafetseng le Motlakase oa Litšoantšo) o khutsufalitsoeng.Qeto e phahameng ea letoto la Effio e pota-potile mela ea 750 - mela ea 800.Ena ke qeto e phahameng ka ho fetisisa e kileng ea fihleloa ke kh'amera ea SD ea analog.Khamera e tloaelehileng ea Effio e na le palo e sebetsang ea pixel ea 976 (e rapameng) x 582 (e theohileng), kahoo e boetse e tsejoa e le kh'amera ea 960H (lipikselse tse sebetsang tse kholo ho feta 960 ka lehlakoreng le tšekaletseng).

Letoto la Effio le ile la qalisoa ho pota 2009, 'me tharollo ea Effio-P e ile ea hlahisoa ka 2012. Ka mor'a moo Sony e tla lebisa tlhokomelo haholo-holo boitekong ba lipatlisiso le nts'etsopele ho CMOS, lik'hamera tsa SD tsa analog le tsona butle-butle li fihla qetellong.

Khamera ea Analog HD

CCD e lahliloeng ke Sony, sepheo se ka sehloohong se tla fetisetsoa ho CMOS ke hobane maemo a ts'oanang a tharollo, litšenyehelo tsa CMOS li tlaase haholo, 'me qeto e phahameng, ho na le lekhalo le leholo la litšenyehelo, e leng se bolelang hore CCD ha e tšoanelehe bakeng sa liqeto tse phahameng. lik'hamera tsa tshireletso.Lik'hamera tsa ts'ireletso ho HD, ntho ea pele e lokelang ho tlosoa ke sensor ea CCD.
