Nigute wahitamo lens nziza kuri kamera yumutekano wawe?

一,Ubwoko bw'inzu ya kamera y'umutekano:

Lens Kamera Yumutekano iza muburyo butandukanye, buri kimwe cyagenewe guhuza ibikenewe byihariye. Gusobanukirwa ubwoko bwa lens iboneka irashobora kugufasha guhitamo iburyo kubishyirwaho kamera yumutekano. Hano hari ubwoko busanzwe bwaLens Kamera:

1,Lens ihamye: Lens ihamye ifite uburebure bumwe nubunini, budashobora guhinduka. Nuburyo buhebuje bukwiye gukurikirana agace runaka adakeneye guhinduka kenshi. Lenyurasiyo ihamye iraboneka muburebure butandukanye, ikwemerera guhitamo umurima wifuza.

2,Leifocal Lens: Lens ya varifocal itanga uburebure bwibanze, ikwemerera guhindura umurima wibitekerezo. Itanga guhinduka muguhindura urwego rwa zoom kandi nibyiza kubihe aho agace gakurikiranwa bishobora guhinduka cyangwa gusaba urwego rutandukanye. Lens Lens isanzwe ikoreshwa muburyo bwo guhinduranya ibisabwa, nkibikurikiranya hanze.

3,Lens zoom:Lens yoom itanga ubushobozi bwo guhindura uburebure bwibanze numurima ureba kure. Irengera zoom ya optique na zoom. Gutyo optique ikomeza ireme ryishusho muguhindura ibintu bya lens, mugihe ya digitale zoom yagura ishusho magiteri, bikaviramo igihombo cyishusho. Indinwa zoom zikoreshwa mubisabwa aho gukurikirana kure nubushobozi bwo gufata ibintu byiza ni ngombwa, nko mubice binini cyangwa hanze.

4,Lens-angle: Lens nini-angle ifite uburebure buciriritse, bikaviramo muburyo bunini. Birakwiriye gukurikirana ibice binini cyangwa imyanya ifunguye aho gufata icyerekezo kinini ni ngombwa. Lens-Angle Lens ikoreshwa muburyo bwo kugenzura nka parikingi, ububiko, cyangwa gukurikirana hanze.

5,Lens ya terefone: Lepheto lens ifite uburebure burebure, itanga urwego rugufi rwo kureba no gukuza cyane. Nibyiza ko ukurikirana cyangwa ibihe bifata amakuru yihariye bivuye kure ni ngombwa. Leselet Lens isanzwe ikoreshwa mubisabwa nko kumenyekana ibimenyetso, isura yo mumaso, cyangwa gukurikirana ingingo zingenzi kure.

6,Lens:Lens ya Pinhole ni lens yihariye ya ntoya kandi ifite ubwenge. Yashizweho kugirango yishwe mubintu cyangwa hejuru, yemerera kwigana kwisi. Lens ya Pinhole ikunze gukoreshwa mubihe bya kamera igomba guhishwa cyangwa umunyabwenge, nko muri ATM, nka ATM, urugi peepholes, cyangwa ibikorwa byo kugenzura.

二,Nigute wahitamo lens nziza kuri kamera yumutekano wawe?

Guhitamo lens nziza kuri kamera yumutekano nintambwe yingenzi mugushikarizwa imikorere myiza no gufatwa amashusho meza ya videwo. Hano hari ibintu bimwe ugomba gusuzuma mugihe uhitamo lens:

Ubwoko bwa kamera:Menya ubwoko bwa kamera yumutekano ufite cyangwa bagateganya kugura. Ubwoko Bumera Bitandukanye, nk'isasu, Dome, cyangwa PTZ (Pan-ly-iltlt-zoom), birashobora gusaba ubwoko bwihariye cyangwa ingano.

Uburebure bwibanze: Uburebure bwibanze bugena umurima wo kureba nurwego rwa Zoom. Yapimwe muri milimetero (mm). Hitamo uburebure bwibanze bujyanye nibyo ukeneye. Hano hari amahitamo asanzwe:

Lens-angle.

Lens isanzwe (8mm kugeza 12mm): itanga ibitekerezo biringaniye bikwiranye na porogaramu rusange.

Indirimbo ya Terefone (12mm no hejuru): itanga urwego runini rwo kureba ariko rutanga ubushobozi bwa zoom bunini bwo gukurikirana urwego rurerure cyangwa ibisobanuro birambuye.

Umwanya wo kureba (Fov): Reba ahantu ushaka gukurikirana kandi urwego rwibisobanuro birakenewe. Umwanya munini wo kureba ni ingirakamaro ahantu hanini hafunguye, mugihe fool nini nini cyane kubice byihariye bisaba kwitegereza neza.

Aperture: Aperture igena ubushobozi bwo gukusanya urumuri. Ihagarariwe na F-numero (urugero, f / 1.4, f / 2.8). Umubare muto F-Umubare werekana aperture yametse, yemerera urumuri rwinshi kwinjiza lens. Aperture nini ni ingirakamaro mubihe byoroheje-byoroheje cyangwa kugirango ifate amashusho asobanutse mu mwijima.

Guhuza Ishusho: Menya neza ko lens ihujwe na sensor igenzura rya kamera yawe. Igishusho rusange cya sensor harimo 1/3 ", 1 / 2.7", na 1 / 2.5 ". Gukoresha lens yagenewe ingano yukuri ifasha gukomeza ubuziranenge kandi yirinde kumvira cyangwa kugoreka amashusho.

Lens mounT: Reba ubwoko bwa laper roma isabwa kuri kamera yawe. Ubwoko busanzwe bwa more burimo CS na c Mount. Menya neza ko lens uhitamo guhuza ubwoko bwa kamera.

Verifocal na Lens ihamye:Lenses ya varifocal igufasha guhindura uburebure bwibanze, itanga guhinduka kugirango uhindure umurima uko bikenewe. Lens Lens ifite uburebure bwibanze kandi utange umurima uteganijwe. Hitamo ubwoko bukwiye ukurikije ibyangombwa byawe.

Ingengo yimari:Reba bije yawe mugihe uhitamo lens. Indinwa-yo mu rwego rwo hejuru hamwe n'ibiranga byateye imbere birashobora kuba bihenze ariko birashobora gutanga ubuziranenge bwiza no kuramba.

Uruganda kandi rusubiramo:Ubushakashatsi abakora ibyuma bizwi cyane muri kamera ya kamera yumutekano. Soma ibisobanuro byabakiriya no gushaka ibyifuzo kugirango umenye ko uhitamo ibicuruzwa byizewe kandi bizwi.

三,Guhitamo lens kubashyior na hanze: itandukaniro ni irihe?

Mugihe uhisemo lens yo murugo cyangwa hanze, hariho itandukaniro rito ritoroshye dusuzumye kubera ibiranga ibidukikije byibidukikije. Dore ibyo ukeneye kumenya:

Imiterere yo gucana:Ibidukikije byo hanze akenshi bifite imiterere itandukanye, harimo urumuri rwinshi, igicucu, nibihe bito-byoroheje mugihe cya nijoro. Ibidukikije byo mu nzu, kurundi ruhande, mubisanzwe bifite amatara agenzurwa hamwe no kumurika. Kubwibyo, guhitamo imigi bigomba kuzirikana ibibazo byihariye byo kumurika bya buri bidukikije.

Hanze:Hitamo lens hamwe na aperture nini (munsi ya F-numero) kugirango ukusanyirizeho urumuri rwinshi muburyo bwo hasi. Ibi bireba neza kugaragara no kwerekana ishusho mugihe cyimbwa, bucya, cyangwa nijoro. Byongeye kandi, lens hamwe nubushobozi bwiza bwo gutanga imbaraga birashobora gukemura itandukaniro riri hagati yizuba nigicucu.

Imbere: Kubera ko ibidukikije byimbere bifite itara rihoraho, lens hamwe na apertures iringaniye birashobora kuba bihagije. Lens hamwe na F-nimero yo hejuru gato irashobora gutanga ubwiza bwiza mumiterere yimbere ntakeneye ubushobozi bwikibazo.

Umwanya wo kureba:Umwanya usabwa urashobora gutandukana ukurikije ingano nimiterere yuburyo.

Hanze: Uturere two hanze dusaba umurima wagutse kugirango ukurikirane umwanya munini neza. Lens-angle Lens ikoreshwa mugufata imyumvire yagutse, cyane cyane kubice bifunguye nkibice bya parikingi cyangwa kubaka imbeba.

Indoor: Umwanya wo kugenzura Indoor urashobora gutandukana bitewe n'akarere kamwe gakurikiranwa. Rimwe na rimwe, lens yagutse irashobora kuba ikwiye gutwikira icyumba kinini cyangwa koridoro. Ariko, muburyo bwo gukomera cyangwa aho bikurikirana birakenewe, lens hamwe numurima munini wo kureba cyangwa ubushobozi bwo guhindura uburebure bwibanze (varifocal lens) birashobora kuguhitamo.

Kurwanya ikirere: Kamera yo kugenzura hanze n'inzira zo hanze igomba guhabwa agaciro ikirere gikaze, nk'imvura, shelegi, umukungugu, cyangwa ubushyuhe bukabije. Ni ngombwa guhitamo lens zagenewe gukoreshwa hanze, akenshi ziza zifite ibintu birwanya ibihe nko ku gahanza kugirango birinde ubushuhe n'imyanda.

Kurwanya kwangiza:Mubidukikije hanze, hari ibyago byinshi byo kwangiza cyangwa kwangiza. Reba lens hamwe nibiranga gukingira nkingaruka-zo kurwanya ingaruka cyangwa dome kugirango wirinde ibyangiritse kandi urebe ko imikorere ya kamera hamwe nubwiza bwishusho butabangamiwe.

Ihuje Ir:Niba sisitemu yawe yo kugenzura irimo infrared (ir) kumurika icyerekezo cyijoro, menya neza ko lens ihujwe numucyo wa Ir. Lens zimwe zishobora kugira iyunguruzo rya IR ryagabanijwe kugirango wongere ireme ryishusho kumunsi mugihe wemereye kumurikira Ir Ijoro.
