Imojula yelensi yePeriscope: ukuphusha imikhawulo yokuthwebula izithombe ngocingo lweselula

Esikhathini sokuthwebula izithombe ze-smartphone, imojula yelensi ye-periscope, enomklamo wayo oyingqayizivele, yephule imikhawulo yokuthwebula izithombe ngocingo lweselula futhi yasuka endaweni ephezulu yaya ekusetshenzisweni kabanzi. Nokho umgwaqo osazobhekana nawo ugcwele izinselelo.

Ilensi ye-periscope, eboleka isimiso se-perope, isebenzisa izibuko namaprism ukugoba indlela yokukhanya, ifinyelela ukusondeza okuphezulu kwe-optical emzimbeni omncane, njenge-OPPO Find8 Ultra, ehlanganisa isistimu yamakhamera amahlanu emzimbeni we-9mm, okuhlanganisa i-6x, i-leperinse ye-telescope enkulu ye-3x yesithombe sokudubula. Nokho, ukuphishekela izilinganiso zokusondeza okuphezulu kudinga ukwandisa inani lamalensi nezici, okwandisa ukulahlekelwa kokudluliswa kokukhanya futhi kunciphisa ukucaca nokugqama kwesithombe; ukwenziwa kwetiyetha kwamalensi kwenza kube nzima kakhulu ukulawula ukuphamba nokushintshashintsha kwe-chromatic, futhi imiphetho yesithombe ijwayele ukufiphazwa futhi ihlanekezele ukusondeza kokukhulisa kakhulu, obekuyinkinga egqamile kumamodeli asekuqaleni, okwenza kube semqoka kakhulu ukukhulisa ukwakheka kokubona nokusondeza kwebhalansi kanye nekhwalithi yesithombe ukuze kuzuzwe impumelelo.

Isikhala sangaphakathi se-smartphone sihlangene, futhi imojula yelensi ye-periscope, ikakhulukazi inguqulo yokukhulisa kakhulu, ithatha indawo enkulu, okuphoqa abakhiqizi ukuthi bahlele kabusha ezinye izingxenye, njengokuklama ukwakheka kwebhethri ngokukhethekile nokudela umthamo othile wokuzivumelanisa nezimo, okuthinta ukusebenza konke kanye nempilo yebhethri ye-smartphone. Ukushisa okukhiqizwe ukusebenza kwemojuli, kuhambisana nokungashisi kahle ukushisa endaweni evalekile, kungaholela kalula ekwehleni kwekhwalithi yesithombe nokuhluleka kwedivayisi, kukwenze kudingeke ukuhlela isikhala ngendlela enengqondo futhi kuxazululwe inkinga yokukhipha ukushisa.

Uma kuqhathaniswa nendabuko ikhamera amalensi e-telephoto, kunegebe kukhwalithi yokuthwebula yamalensi e-periscope. Ngamalensi amancane nokuvuleka okulinganiselwe, ahlushwa indawo yokukhanya enganele ekukhanyeni, okuholela emsindweni omkhulu, futhi lapho kudutshulwa izigcawu zasebusuku noma ekukhanyeni okuphansi, izindawo ezimnyama azinayo imininingwane nokuthungwa; ezigcawini zobubanzi obuguquguqukayo obuphezulu, ububanzi obuguquguqukayo obuncane buvame ukuphumela ekuchayekeni ngokweqile nasekuchayekeni kancane, futhi umbala nemininingwane yokukhiqiza kabusha kuyahlanekezelwa. Idizayini yokubona, ubuchwepheshe bezinzwa, kanye ne-algorithm kumele kusungulwe ndawonye ukuze kuthuthukiswe ikhwalithi yokucabanga.

Bebhekene nalezi zinselele, abakhiqizi bahlola ngenkuthalo. Ekwakhiweni kwe-optical, bakha izinto ezintsha zamalensi kanye nokunciphisa ukulahleka kokukhanya nokuphambuka; ekuhlelweni kwesikhala, basebenzisa izixazululo ezihlangene, ezihlanganisa kakhulu ukunciphisa umthelela kwezinye izingxenye; futhi ekuthuthukiseni ikhwalithi, bakhulisa utshalomali ocwaningweni nasekuthuthukisweni kwezinzwa, bathuthukise ama-algorithms, futhi basebenzise ukuqashelwa kwesigcawu esihlakaniphile, i-HDR yesikhathi sangempela, nobunye ubuchwepheshe ukuze kuthuthukiswe isithombe. Imojuli yelensi ye-periscope ibhekene nezinselelo eziningi, kodwa inamandla amakhulu, futhi ngenqubekela phambili yezobuchwepheshe, izoletha ukukhuphuka okuphakeme ekuthwebuleni izithombe ngefoni yeselula isiza ama-smartphones ukuthi angene enkathini yokuthatha izithombe ezibanzi.
