Iingcebiso zeNgcali zokukhetha eyona khamera yewebhu igqwesileyo

Ukuba iiwebcams ngoku ziyinxalenye ebalulekileyo yonxibelelwano lweshishini ihamba ngaphandle kombuzo. Amashishini amaninzi, nokuba angakanani na, amkela ukusebenzela kude, kwaye iintlanganiso zenyani ziyanda. Ukuqonda iimpawu ezahlukeneyo zekhamera yewebhu kunokukunceda wenze izigqibo zokuthenga ezingcono malunga nokuba loluphi uhlobo olungcono lokufumana.

Iiwebcams zangaphandle vs. iiwebcams zangaphakathi

Igama elithi "webcam" ngoku liphantse lafana nelinye laptops, nangona ingazange isetyenziswe, kwaye iikhamera zewebhu zangaphandle zisenazo izibonelelo zazo. Ngelixa umndilili efowuni kule mihla ilayishwe ngeekhamera ezithatha imifanekiso enesigqibo esiphezulu kunye neevidiyo ukwenza imbonakalo endilisekileyo ngexesha leentlanganiso zenyani, ukuphuma kwebhetri okukhawulezileyo kuhlala kungumda omkhulu. Oku ke kwenza iilaptops zibe lukhetho oluthembekileyo ngeenjongo ezinjalo. 

Nangona kunjalo, mnye umbuzo oseleyo: "Ngaba i-webcam yewebhu ephakathi ilungile ngokwaneleyo?" Akusoloko, ngesizathu esinye esilula: Ikhamera yewebhu yangaphakathi, efana nekhamera eyakhelweyo ngaphakathi, yenye yezinto ezininzi ekufuneka zibe nazo abenzi beelaptop abapakisha kwiimveliso zabo ngelixa bezama ukuzigcina zinexabiso elifanelekileyo. Sisenzo esinzima sokulinganisa kwaye, rhoqo, esibangela ukuba umgangatho wekhamera ubandezeleke. 

Xa kuthelekiswa nekhamera yewebhu ye-USB yangaphandle, ikhamera yewebhu yangaphakathi ihlala ibonelela ngomgangatho ophantsi womfanekiso kunye nokucaca kwelizwi ngenxa yokusetyenziswa kwezixhobo ezikumgangatho ophantsi. Iilaptops zihlala zinemiba yokufudumeza, kwaye amandla okucoca ukukhanya kunye nokugxila kwekhamera kudla ngokuba semngciphekweni, nto leyo eyenza ukuba iiwebcams zangaphakathi zinganqweneleki kakhulu kwiinjongo zenkomfa yevidiyo. Ukunyuselwa kwikhamera yewebhu yangaphandle kuza ngexabiso elincinci elongezelelweyo kodwa kuthembisa umgangatho ongcono, iimpawu, ukuqina, kunye namava omsebenzisi. 

Iimpawu ezibalulekileyo zekhamera yewebhu

Ngoku siyaziqonda iingenelo zokusebenzisa i Ikhamera yewebhu ye-USB yangaphandle, masingene phakathi kweziphi iimpawu ezibalulekileyo ekufuneka sizijonge.

Resolution

Ukucaca komfanekiso kunye nomgangatho wevidiyo zezinye zezalathi ezicacileyo zokusebenza kwekhamera. Ke ngoko, kubalulekile ukujonga isisombululo sekhamera yewebhu. Izahlulo ezintathu ezibanzi zesisombululo phakathi kweewebcams zangaphandle zezi:

1280 x 720 pixels (HD Ready okanye 720p): Esi sesona sisombululo sisezantsi ngokubanzi phakathi kweewebcams zanamhlanje kodwa sihlala sisaziwa ngokusasaza bukhoma kunye neenjongo zenkomfa yevidiyo. 

1920 x 1080 pixels (iHD epheleleyo okanye 1080p): Le khamera yewebhu enesisombululo esiphezulu lolona khetho lukhethwayo kubasebenzisi beshishini abafuna inkangeleko engaphezulu yobuchwephesha kwiscreen.

3840 x 2160 pixels (Ultra HD okanye 4K): Ezi khamera zewebhu zinesombululo esiphezulu zikhethwa ikakhulu kwiinjongo zokuhlela ividiyo ezikumgangatho ophezulu kwaye ziza nethegi yexabiso eliphakamileyo.

Ngoko ke, kwiimeko ezininzi, 720p kwaye 1080p iiwebcams zanele, kuxhomekeke kwiimfuno zomntu kunye nohlahlo lwabiwo-mali.

Umgangatho wefreyimu

Kungenjalo kwaziwa njengezakhelo ngomzuzwana (fps), ireyithi yesakhelo ikwaliphawu elibalulekileyo lokumisela ukusebenza kwekhamera yewebhu njengoko ibonisa ukuba ividiyo iya kuba lula kangakanani na. Ukuqala ukusuka kwi-30fps ephantsi ukuya phezulu ukuya kuthi ga kwi-120fps, iiwebcams ezona ziphezulu nezifikelelekayo zikholisa ukuza ne-60fps enesisombululo se-720p okanye i-30fps enesisombululo se-1080p.

Iilensi zekhamera 

Kukho izinto ezimbini ezibalulekileyo ekufuneka ziqwalaselwe malunga nelensi yekhamera yewebhu: ukwakhiwa kwayo kunye nendawo yokujonga. Iilensi zeWebcam ziza ngeglasi kunye neentlobo zeplastiki. Ngaphandle kwexabiso eliphezulu, kububulumko ukukhetha yangaphambili njengoko iglasi ilula ukuyikrwela, ngaloo ndlela inika ukucaca okungcono kunye nokuqina.

Intsimi yokujonga (i-FOV) ibonisa ububanzi bendawo ebanjwe yi-lens yekhamera yewebhu kwaye isuka kwii-degrees ze-60, ibambe umntu omnye, ukuya kwii-90 degrees, ibambe iqela labantu. Ukhetho lwakho luya kuxhomekeka kwinto efunwa ikhamera yewebhu. 

Imakrofoni eyakhelwe ngaphakathi

Olunye uphawu olubalulekileyo kodwa oluhlala lungahoywa lwekhamera yewebhu ngumbhobho owakhelwe ngaphakathi, ovumela amava e-video-conferencing engena-clutter-free. Ezinye iiwebcams zide zibe nazo iimayikrofoni ezimbini ezakhelwe ngaphakathi (okanye ii-omnidirectional) ezinceda ukubamba isandi sendalo ngakumbi. Ngelixa ii-microphone zangaphandle ngokuqinisekileyo zinomgangatho ophakamileyo wesandi, ukuphucula itekhnoloji ye-microphone eyakhelwe-ngaphakathi kwiikhamera zewebhu kubanceda ukuba bafumane ukuthandwa okukhulu phakathi kwabasebenzisi.

Iimpawu ezongezelelweyo ezinenzuzo yewebhu yewebhu

Iimpawu zewebhu ezingabalulekanga azithethi ukuba kufuneka zingahoywa. Nazi ezimbalwa ezifanele ukukhankanywa ngokukhethekileyo.    

I-Autofocus kunye nokulungiswa kokukhanya okuphantsi

Ubunjani bomfanekiso obumfiliba bunokuphazamisa kwaye buphazamise ngexesha lokusetyenziswa kwekhamera yewebhu. I autofocus feature ke ngoko iza luncedo njengoko ijolise ngokuzenzekelayo ikhamera kumxholo endaweni yangasemva. Iiwebcams ezihambele phambili ngakumbi zinenzuzo eyongezelelweyo yokujonga ngokukhawuleza okuzenzekelayo, nkqu nakwiindawo ezixakekileyo.

Nangona kunjalo, ukugxila kwe-auto kunokusilela kwiimeko ezingakhanyiswanga kakuhle, njengasekuseni nangokuhlwa. Ukukhetha ikhamera yewebhu enento yokulungiswa kokukhanya okuphantsi kusombulula le ngxaki, ukonyusa ukusebenza kwe-autofocus kuzo zonke iimeko zokukhanya. Ezinye iimodeli zewebhu ezikwisiphelo esiphezulu zikwakhona nezibane ezakhelwe ngaphakathi, ezivumela umsebenzisi ukuba alungelelanise inqanaba lokukhanya.

Ukuhlolwa okuluhlaza

Kusenokubakho izizathu ezininzi zokuba kutheni umsebenzisi anokufuna ukwenza mfiliba imvelaphi yakhe ngexesha lomnxeba wevidiyo - ukusuka ekufihleni imvelaphi ephithizelayo ekukhuseleni ubumfihlo bomntu. Ukuhlola okuluhlaza luphawu olukhethekileyo olufumanekayo ngezinye iikhamera zewebhu ezithi, ngaphandle kokwenza mfiliba, ziphinde zitshintshe imvelaphi yesifundo ngokokuthanda kwabo.

Isoftware inkxaso

Nabani na osebenzisa ikhamera yewebhu enobutyebi anokuzuza kwinkxaso yesoftware. Ngokusebenzisa ulawulo lwesoftware, umsebenzisi unokuseta izinto azikhethayo kwinqaku ngalinye, ngaloo ndlela ebanika ulawulo olukhulu ekusebenzeni abakufunayo kwikhamera yewebhu.

isishwankathelo

Ngamafutshane, ukuthenga ikhamera yewebhu yangaphandle kukutyalomali olulumkileyo kumashishini okanye abo bakwimigca esemthethweni yomsebenzi. Ukugxila kwiimpawu ezinxulumene nomfanekiso, ividiyo, kunye nomgangatho womsindo kunokunceda umthengi afumane iziseko ezichanekileyo, ngelixa ukuqonda iimpawu ezongezelelweyo zekhamera yewebhu kunokunceda abasebenzisi ukuba bafumane okuninzi kubuchwephesha babo.

Njengoko ihlabathi liqhubeka licutheka ngokwedijithali, imfuno yokugcina umelo oluyinyani ngokusebenzisa izikrini iya ibaluleke kakhulu. Ukuthenga ikhamera yewebhu elungileyo ehambelana neemfuno zeshishini lomntu kunye nesimbo kulutyalo-mali olunexabiso kunye noluncinci olunokuhlawula ekuhambeni kwexesha. I yembutho namhlanje izaliswe ziikhamera zewebhu ezingapheliyo, ngoko ke ukuqhelana neempawu kunokukunceda wenze ukhetho olufanelekileyo ngokukhawuleza.Hlala phezu kweendlela zamva nje kwaye ufumane ulwazi oluninzi lweshishini, ulwazi lweengcali, kunye neendaba zeB2B ngexesha elifanelekileyo UChovm uyafunda.
