Ungaqinisekisa Kanjani Ukulungiswa Kwamalensi Ezimboni? Iyini Imisebenzi Yawo?

1,Ungaqinisekisa kanjani ukuxazululwa kwamalensi ezimboni?

Ukuqinisekisa isinqumo se-ilensi yezimboni, ezinye izilinganiso nokuhlolwa kuvame ukudingeka. Ake sibheke izindlela eziningana ezivamile zokuqinisekisa ukucaca kwamalensi ezimboni:

Ukulinganiswa kwe-MTF

Amandla okuxazulula kwelensi angahlolwa ngokuhlola i-Modulation Transfer Function (MTF) yelensi. Ukulinganiswa kwe-MTF kungaveza ikhono lelensi lokudlulisa imininingwane ngamaza ahlukene kanye nokuqhathanisa, ngaleyo ndlela kwahlulelwe ukusebenza kwelensi.

Isithombe sokuhlolwa kwesisombululo

Sebenzisa isithombe sokuhlola isixazululo esinomehluko omkhulu kanye nemininingwane ukuze uhlole ikhono lesisombululo selensi. Ngokubheka imininingwane kanye nezimo zomphetho esithombeni, ungaqale wahlulele ukusebenza kwesisombululo selensi.

Sebenzisa izithombe ukuhlola isixazululo

Sebenzisa amashadi okuhlola isixazululo

Ezinhlelweni ezisebenzayo, ukulungiswa kwelensi kungahlolwa kusetshenziswa amashadi okuhlola ukulungiswa aklanyelwe ngqo ukuhlola ukulungiswa kwelensi. Lawa mashadi aqukethe uchungechunge lwemigqa noma amaphethini amancane akuvumela ukuthi uhlole ukulungiswa kwelensi ngokubheka ukuthi la maphethini abukhali futhi abonakala kangakanani esithombeni.

Sebenzisa imishini yobungcweti

Uma kudingeka isilinganiso sesisombululo esinembile kakhudlwana, imishini yobuchwepheshe yokukhanya kanye nesofthiwe kungasetshenziswa ukwenza izivivinyo zesisombululo ezinemininingwane eminingi.

Bheka ikhwalithi yesithombe

Ungakusebenzisa lokhuilensi yezimboniukudubula into nokubona ukucaca nemininingwane yesithombe. Uma isithombe sicacile, sinemininingwane, futhi sinombala oqondile kanye nokuqhathanisa okuphezulu, kusho ukuthi ilensi ingaba nesisombululo esiphezulu.

Imininingwane yomkhiqizi wereferensi

Abakhiqizi bamalensi bavame ukunikeza ulwazi mayelana nesinqumo selensi kuncazelo yomkhiqizo, kufaka phakathi idatha efana nenani lesinqumo esiphezulu noma ijika le-MTF. Ungabhekisela futhi kuncazelo enikezwe umenzi ukuze uqonde ukusebenza kwesinqumo selensi.

2,Yimiphi imisebenzi eyinhloko yamalensi ezimboni?

Njengelensi ekhethekile yokukhanya yezinhlelo zokusebenza zokubona kwezimboni, imisebenzi eyinhloko yamalensi ezimboni ifaka okulandelayo:

Ukutholwa Nokuhlonza

Amalensi ezimboni, uma ehlanganiswa namakhamera nemithombo yokukhanya, angasetshenziswa ukuthola amaphutha ebusweni, ukukala ubukhulu, ukuhlonza umbhalo noma amaphethini, nokufeza ukulawulwa kwekhwalithi okuzenzakalelayo kanye nokuqapha inqubo yokukhiqiza. Lokhu kuthuthukisa ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo.

Imisebenzi yamalensi ezimboni

Ukutholwa Kwesithombe

Amalensi ezimboniingathwebula izithombe ezinesinqumo esiphezulu, eziphambene kakhulu, ezingafani kakhulu, iqinisekisa ukucaca nokunemba kwezithombe ezithwetshuliwe, inikeze isisekelo esithembekile sokucutshungulwa nokuhlaziywa kwezithombe okulandelayo.

Ukutholwa Kwedatha

Idatha yesithombe etholwe ngamalensi ezimboni ingasetshenziswa ekuhlaziyweni kwezibalo, ukuqoshwa kwedatha, kanye nokuxilongwa kwamaphutha, okusiza amabhizinisi ukuthi athuthukise futhi athuthukise izinqubo zawo zokukhiqiza.

Isiqondiso Esibonakalayo

Amalensi ezimboni angasetshenziswa emisebenzini efana nokubeka, ukuzulazula, kanye nokuqashelwa ezinhlelweni zokubona komshini, ukuhlinzeka ngesiqondiso esibonakalayo samarobhothi nemishini ezenzakalelayo, kanye nokufeza ukukhiqizwa nokusebenza okuzenzakalelayo.

Imicabango Yokugcina:

UChuangAn wenze umklamo wokuqala kanye nokukhiqizwa kweamalensi ezimboni, ezisetshenziswa kuzo zonke izici zezicelo zezimboni. Uma unesithakazelo noma unesidingo samalensi ezimboni, sicela usithinte ngokushesha okukhulu.
