Ngati pali zipinda zingapo, mutha kugwiritsa ntchito zizindikiro zazing'ono za analog (zochepa mpaka 3,000).
Kuwonera pa intaneti
GULUMBO
Zida zonse zowonera makanema zomwe zilipo pamsika zitha kugawidwa m'magulu atatu: amwenye, odziwika a ku Asia ndi ena odziwika. Ktreyim amaphatikiza pakati pa zinthu zina ndi zinthu zopanga zazikulu zamagetsi (komanso, panjira, kwa Asia). Ndimafuna kudziwa kuti maguluwa ndi ochezeka kwambiri osagwirizana ndipo sakupikisana wina ndi mnzake.
Kamera MVK-08 Ard imasintha zokha za diaphragm, kamera yomwe imapangidwa ndi Baierg (Russia) imaphatikiza kudalirika kwakukulu komanso mtengo wotsika. "Mahatchi" amenewa ndi amodzi omwe amaperekedwa mu anti-Varmal magwiridwe antchito ndikutetezedwa ku fumbi ndi chinyezi. Komabe, mtundu wachitsanzo pano ali m'chipinda chachikulu kwa kukhazikitsa panja, ndipo pali zida zingapo za zida mu khomo ndi kanema. Mitengo yamitengo - 1.5-10 zigwa zikwizikwi.
Mtengo wa makamera opanda zingwe ochokera ku China ndiotsika kangapo kuposa mtengo wazinthu zopanga zodziwika bwino. Koma ndi kuwononga anthu oyamwitsa akuwoneka kuti amadziwa bwino konse, ndipo makadi a kanema m'makamera oterewa sakhala owala. Mitundu yambiri imagulitsidwa pansi pa chidule cha alphanumeric.
Makampani akuluakulu, monga jvc, Sanyo, Panyosonic (onse Japan), Samsung (Korea) ndi osewera akale. Amapanga zipinda zamtengo wapatali (kuchokera ku ma ruble 7,000 pa zosankha zosavuta), koma m'malo mwake amapereka mtundu wambiri ndikutsimikizika. Koma makamera a opanga zinthu zopangira zovuta samawerengedwa, ndiye kuti, amaganiza kuti adzakhazikitsidwa m'malo. Komabe, monga njira, thermocons yapadera ndi anti-Vandal "imaperekedwanso. Komabe, mtengo wa amoyo woterowo umafika nthawi zina mpaka mtengo wa kamera yokha.
Mwachidziwikire, tsogolo la machitidwe oyang'anira makanema ndi kuchuluka kwawo kwa ma network ndi materikinoli apamaneti. Zowonadi, pankhaniyi, zopangidwa padziko lonse lapansi zimagwiritsidwa ntchito, ndipo vuto la kukhazikitsa limathetsedwa. Mbali yolimba, makamera apamwamba safuna luso lapakompyuta komanso chifukwa cha kuphweka kwawo kodalirika.
Mwachikondi, mlandu wopanga makina ogwiritsira ntchito bwino ayenera kukhala osasinthika ndi akatswiri. Tikukhulupirira kuti nkhani yathu ikuthandizani kuti mulankhule nawo m'chinenedwe chimodzi kapena mosavuta kunena zofuna zanu ndikumvetsetsa tanthauzo la zosankha. Kupatula apo, zovuta zosankha imodzi mwa izo zikugwera.
Mtundu wa matrix. Matrix "Mtima" wa Camcorder: Amatembenuza mtsinjewo. Pali mitundu iwiri ya matrics: CCD (CCD) ndi CMOS (CMO). Onsewa ndi oyenera kuyang'anira makanema: Ndizofanana, chifukwa zimasiyana pokhapokha powerenga zambiri. Matinsi a CMOS amasiyanitsidwa ndi phokoso lochuluka, koma amagwira ntchito ndi kugwiritsa ntchito mphamvu zochepa, kotero kuti m'magulu okhala ndi chakudya, atha kusankha kusankha kamera ndi sensor.
Diagonal matrix. Kukula kwa matrix kumatsimikiziridwa ndi kuchuluka kwa zigawo za zigawo zake ndipo, motero, kukula kwa chilichonse. Ambiri amakhulupirira kuti ochepera matrix, abwino, komabe, malamulo a chisinthiko amagetsi pankhaniyi sakugwira ntchito. Chiwerengero cha zinthu mu matriries ndizofanana, koma matrix ang'onoang'ono amadziwika ndi phokoso lalikulu la zamagetsi komanso kumva bwino, zomwe zimafotokozedwa mu tirigu wowonjezereka, ngati zibwera kupita kuchipinda cha utoto. Matrics mu zipinda zachitetezo kwambiri amakhala ndi zilembo za 1/3 (pafupifupi 8mm). Kuyang'ana ma matric 1/2-inch.
Kusintha. Parameter iyi imatsimikizira momwe zimapangidwira chithunzicho kuchokera pa kamera. Kwa makina oyang'anira makanema (ndi TeleVog Televizioni, ambiri), gawo la muyezo - mizere ya pa TV (mwachitsanzo, TVl) imatanthawuza kuti zitheka kusiyanitsa ndi mizere 400. Pankhaniyi, chilolezo sichitha kupitirira bala, chinagona pansi muyezo wofotokozera (mwachitsanzo, mu PAL-625 mizere).
Izi zikuwonekeratu kuti makamera akuda ndi oyera. Izi zimachitika chifukwa chakuti ali ndi chithunzi chimodzi cha khungu limodzi, pomwe chifukwa chake kusinthika kosintha kosasinthika ndi kochepa, pomwe khungu lofananalo limapangidwa ndi zinthu zitatu ndi zosefera zogwirizana ndi RGB.
Kuthetsa kwa makamera digito kumawonetsedwa ku pixel mbali za chimango, mwachitsanzo: 640480 pixel. Momwemonso, vidiyo yolembedwa mu mawonekedwe a digito imadziwika, kuphatikiza ndi thandizo la wolemba kanema.
Kuyika chidwi. Ngakhale matrics amakono ali ndi mitundu yopaunikirapo, ndiye kuti, ndiyotheka kufalitsa chidziwitso chokwanira kunyezimira. Kuperewera kumeneku kumalipiridwa ndi kusintha kwadzidzidzi kwa nthawi: Zenera laling'ono laling'ono lakanthawi likhoza kuwunikira chimango kuti chijambule (mpaka 1/100), 1/50 s) amapita. Kuphatikiza apo, kuti mupeze chithunzi chomveka bwino, chizindikiro chochokera ku matrix chikukulitsidwa, podutsa phokoso laphokoso. Komabe, zonsezi zimakhala ndi malire pa chidwi cholowera. Uwu ndiye gawo la kuwunikira chinthu chomwe chawonedwa, chomwe ndi chovomerezeka (kapena pansipa chomwe chimawoneka ngati kamera). Kuphatikiza pa mtundu wa kamera, imachokera ku magawo khumi kupita ku zana la suti. Mwachitsanzo, tikuwona kuti kuwunikira kuti nyengo yowala nthawi ya dzuwa imatha kufika pa 3,000 LC, pafupifupi 100 lcs ndipo, kumapeto, nthawi yocheperako, yocheperako 0,01 lc. Mwachidziwikire, popanda njira zapadera mu mdima wamdima, kamera iliyonse imakhala yakhungu kwathunthu.
Kuwonekera kuwunikira. Kutulutsa kwa radiation kumadziwika ndi zithunzi zilizonse zokulirapo kuposa kuona kwa munthu, ndipo ngati camkorder (ndiye kuti Seesor waiwo waikidwa ngati tochi. Katunduyu amagwiritsidwa ntchito kuwunikira malo owonera nthawi yomwe mulingo wowunikira ali pansi pa chidwi cha kamera. Chithunzicho chimapezeka ndi monochrome.
Kusintha kwa diaphragm (Ard). Kusiyanitsa kwakukulu kumayambitsidwanso chifukwa cha kuchuluka kwa kuwala komwe kukugwa pamatrix. Komabe, njirayi siyithandiza kwambiri kukulitsa chidwi, kuchuluka kwake kumathetsa kuwunikira mu nyengo yokwanira ndikuwonjezera lakuthwa. Chifukwa chake, magalasi okhala ndi Ard amamveka kugwiritsa ntchito makamera amsewu. Pankhaniyi, mwayi wowongolera ku diaphragm kuyenera kuthandizidwa ndi kamera, chifukwa lamulo kuti musinthe bowo la mandala a diaphragm limapezeka ndi chingwe chapadera.
Kutalika kwambiri. Makona ofala a Camcorder amatengera kutalika kwa mandala (omwe ndi ochepa, mbali yodutsa ", komanso yocheperako ya matrix? kutalika kofanana. Ndi mtunda wa 3.6mm ndi 1/3-inch match, ngodya ya View ndi 78. Ili ndiye njira yofananira. Zogwira ntchito zapadera, kuphatikiza kwa matrix ndi mandala amagwiritsidwa ntchito, kupereka ziwonetserozi pofotokoza gawo limodzi mpaka 150. Chifukwa chake, kamera yowonera yaying'ono ndiyoyenera kuwunika gawo laling'ono pamtunda wofunikira, kumbuyo kwa gazebo m'munda , ngati palibe kuthekera kuyika kamera pomwepo. Makamera ambiri omangika amapezeka mu vidiyo yavidiyo: amagwira malo okwanira, osataya madera akufa.
