Usebenza njani umsebenzi we-len? Yeyiphi iparamitha endimele ndiyiqwalasele?

A I-Scan Scan LensNgaba i-lens ekhethekileyo isetyenziswa ikakhulu kwiikhamera zeskena. Yenza iskena esikhawulezayo esiphezulu sicinga kumda othile. Yahlukile kwiilebhu zekhamera zemveli kwaye zihlala zisetyenziswa kwicandelo lemizi-mveliso.

Yintoni umgaqo wokusebenza weskenaI-lens?

Umgaqo wokuSebenza we-Scan Scan Ilensi isekwe ikakhulu kwiteknoloji ye-Scan. Xa usebenza, iskeni iskeni i-lens ibeka umphezulu womphezulu womgangatho ngomgca kwaye uqokelele ulwazi lokukhanya komqolo we-pixels ukuba ifake umfanekiso wonke endaweni yokufaka umfanekiso wonke.

Ngokukodwa, imigaqo-siseko yokuSebenzisa i-Scan Scan inamanyathelo aliqela:

Ukucinga okuphezulu:Inqaku lokukhanya lesampulu ukuba iskenwe yi-scan-fat ifakwe izinto ezifotileyo zomgca kwi-intanethi kwilensi yomgca kwaye iguqulwe ibe yimiqondiso yombane.

I-Line-Ine-LineI-Line-Bline-Line-Line-Line-Line Scans Scans ukusuka phezulu ukuya ezantsi kwesampulu ngesantya esithile, iguqula ulwazi lokukhanya lomgca ngamnye kube ngumqondiso wombane.

Ukulungiswa kwesiginali:Emva kokulungiswa, umqondiso wombane uguqulwa ube ngumqondiso wedijithali wokufumana umfanekiso.

I-Stitch yomfanekiso:Hlanganisa kunye imiqondiso yedijithali yomqolo ngamnye ukuba ibe ngumfanekiso wesampulu yonke.

Umgaqo wokuSebenza weScan Ilensi

Yeyiphi iparamitha ekufuneka ihlawulwe ingqalelo kwi-Scanses Scanses?

Iiparameter zeI-Scan Scanseszinxulumene ngokusondeleyo neemfuno ezahlukeneyo kunye nemeko yesicelo. Ezi paramitha zilandelayo kufuneka zijolise kuzo:

Isisombululo

Isigqibo seskena somgca iskena ihlala ibaluleke kakhulu kwi-metric eziphambili. Ukuphakama kwesisombululo, ukuphakamisa ukucaciswa kwemifanekiso, okunxulumene nenani leephikseli kwindawo yokucinga kunye nobungakanani bento ebonisa ingcinga.

I-aperture

Ubungakanani be-aperture ilawula ubungakanani bokukhanya okungena kwilensi, ichaphazela ukuqaqamba kwe-lens kunye nexesha lokubonisa le filimu. I-aperture enkulu inokuphucula umgangatho wemifanekiso xa isetyenziswa kwiimeko eziphantsi, kodwa zinokunciphisa uluhlu olunzulu.

Uluhlu lokujonga

Uluhlu lokugxila lubhekisa kumgama olona luhlaza lunokudubula lensi. Ngokubanzi, i-tider ebuthile, kwaye ibanzi kuthetha ukuba ingatola izinto ezininzi zobude obujolise kuzo.

Ukuphakama komfanekiso

Ukuphakama komfanekiso kubhekisa kubude bemifanekiso yensimbi kwi-lens kwi-scanning. Ukuphakama komfanekiso omkhulu kufuna isantya sokuncancisa ngokukhawuleza, okuya kukhokelela kwisantya esiphezulu sokucinga kunye nenqanaba eliphezulu lokuhambisa idatha.

Gxila kumgangatho womfanekiso

IUmgangatho osemgangathweni

Ukucingisisa umgangatho kungalinganiswa ziiparamitha ezinje ngesisombululo se-Latteral, umlinganiso wesayizi, kunye nombuso wombala. Ngokwesiqhelo, isisombululo esiphezulu se-Lateral, umyinge-wengxolo, kunye nombuso wombala ithetha umgangatho ophezulu.

Ubungakanani beelensi kunye nobunzima

Ubungakanani kunye nobunzima bunokuchaphazela ukusetyenziswa kweI-Scan Scanseskwezinye iinkqubo. Ke ngoko, ubungakanani nobunzima belensi kufuneka kuthathelwe ingqalelo ngokwemeko ezahlukeneyo zesicelo.

Iingcinga zokugqibela:

Ukuba unomdla wokuthenga iintlobo ezahlukeneyo zeelensi zokujonga, ukuskena, iidrones, ikhaya, okanye naluphi na olunye usetyenziso, sinayo into oyifunayo. Nxibelelana nathi namhlanje ukuze ufunde ngakumbi malunga neelensi zethu kunye nezinye izinto.
