Ukuqhathaniswa kwe-Smartphone Camera Anti-Shake Technology: i-OIS, i-EIS, kanye neMpi Yesistimu Yokuqinisa I-Six-Axis Hybrid Stabilization

Njengoba imisebenzi yokuthatha izithombe yama-smartphones iqhubeka nokuphindaphinda futhi ithuthukiswa, ubuchwepheshe bokulwa nokuzamazama buye baba ngesinye sezici ezibalulekile ezinquma ikhwalithi yomkhiqizo wokugcina. Kusukela ezithombeni, izigcawu zezemidlalo kuya ekudalweni kwezigcawu zasebusuku, isidingo sabasebenzisi sokuqina kwesithombe sikhula usuku nosuku. Lesi sihloko sizohlaziya ngokujulile izimiso zobuchwepheshe nokusebenza kwe-OIS evamile yamanje (Optical Image Stabilization), ICE (I-Electronic Image Stabilization) kanye namasistimu wokuzinzisa ama-axis ayisithupha ukuze akusize wenze ukukhetha okunolwazi lapho uthenga.

I-OIS isisombululo sakudala esidumile sokulwa nokunyakazisa, esinxephezela imiphumela yokundindizela kwesandla ngokugudluzwa ngokomzimba kweqembu le-lens noma inzwa. Umgomo wayo uwukubheka i-gyroscope ukuthola isiqondiso kanye nobukhulu bokuzamazama kweselula, kanye nokushayela imoto encane ukuze ulungise indawo yelensi ukuze ugcine ukukhanya kuzinzile. I-OIS yendabuko ine-engeli yokunyakazisa ngokuvamile engu-±1°, futhi inezinzuzo ezisobala endaweni yokukhanya okuphansi, ngokwelula isikhathi sokuchayeka ukuze kuthuthukiswe ukukhanya, kuyilapho kunciphisa ukufiphala.

Izinzuzo: Umthelela ophansi kukhwalithi yesithombe, asikho isidingo sokudela amaphikseli noma ukunqampuna kwesithombe; Ivelele ekukhanyeni okuphansi, ifanele isigcawu sasebusuku, isithombe esinokukhanya okuphansi nezinye izimo.

Ukulinganiselwa: Izindleko eziphezulu zehadiwe, indawo enkulu yokuhlala; Lim anti-Shake range, kunzima ukubhekana nokunyakaza okunodlame noma ukudlidliza kwefrikhwensi ephezulu.

I-EIS ithembele kuma-algorithms ukuze ifinyelele ekulweni nokunyakaziswa, ngokuhlaziya umehluko phakathi kwamafreyimu evidiyo, iguqule ngokushintshashintshayo indawo yokunqampuna yesithombe ukuze inxephezele ukunyakazisa Umgomo wayo ufana "nonqampuna olushintshashintshayo", kusetshenziswa amaphikseli onqenqema wenzwa ukuze asuse ukuzamazama, kodwa izodela inkambu ethile yokubuka nokuxazulula.

Izinzuzo: Akukho hardware eyengeziwe edingekayo, izindleko eziphansi futhi kulula ukuhlanganisa; Sekela amalensi ama-angle abanzi, afanele ukushuthwa kwevidiyo yezemidlalo

Imikhawulo: Ukulahlekelwa kwekhwalithi yesithombe okuphawulekayo, ikakhulukazi ezindaweni zokukhanya okuphansi lapho umsindo ukhuphuka khona; Umthelela we-anti-shake unqunyelwe inzwa, futhi amamodeli asezingeni eliphezulu enza kangcono.

Ubuchwepheshe be-anti-shake obunama-axis ayisithupha (obufana ne-Vivo's micro gimbal, i-Huawei's Sensor Shift) yisixazululo esisha esivele eminyakeni yamuva nje, sihlanganisa ukuzinza komzimba kwe-OIS nokwenza ngcono kwe-algorithm ye-EIS. Ukuthatha i-gimbal encane ye-Vivo njengesibonelo, yamukela isakhiwo "sokumiswa kwebhola elikabili", futhi ngohlaka lokunyakaza olungavamile kazibuthe, ifinyelela i-angle yokunyakazisa engu-±3 °, ehlanganisa indawo engu-3. izikhathi ezingaphezu kwe-OIS yendabuko. Ihlanganiswe ne-algorithm yokuthola ukunyakaza kwe-AI, ingalandelela futhi inxephezele ukuzamazama okuyinkimbinkimbi ngesikhathi sangempela.

Amakhefu Obuchwepheshe:

1.I-anti-shake ye-Multi-dimensional: Isekela ukuhunyushwa kwe-eksisi ye-X/Y kanye nesinxephezelo sokuzungezisa i-R-eksisi, ehlanganisa izikhombisi-ndlela zokunyakaza.

2.Isinxephezelo esinamandla: Ngokunciphisa isikhathi sokuchayeka nokuthuthukisa i-algorithm yokugxilisa ingqondo, izinga lempumelelo lezifinyezo zezemidlalo liyathuthukiswa.

3. Ukuthuthukiswa kokukhanya okuphansi: Kuhlanganiswe izinzwa ezinkulu zokuvula (ezifana ne-f/1.6) kanye nokunciphisa umsindo wesizinda RAW, ukuthwebula izithombe ebusuku kuhlanzekile.

Izimo Zokusebenza Ezijwayelekile:

1.reme ukudubula kwezemidlalo (i-skateboarding, ukuhamba ngebhayisikili).

2. Isigcawu sasebusuku esiphathwa ngesandla isikhathi eside.

3. Ukugxila kwevidiyo nokunyakaza kwe-cinematic.

Ikhwalithi yesithombe se-Pue: Khetha i-OIS noma isistimu ye-hybrid ye-axis eyisithupha kuqala, enenzwa enkulu;

Gxila kuvidiyo: Amasistimu ayingxube ye-axis ayisithuphanjenge-gimbal encane) Inhlanganisela ye-EIS izinze kakhulu;

Isabelomali esinomkhawulo: Uhlelo lwe-EIS lunokusebenza kwezindleko eziphezulu, kodwa ludinga ukulahlekelwa kwekhwalithi yesithombe.

Njengoba ubuchwepheshe be-AI buthuthuka, izixazululo zokulwa nokuzamazama ziyashintsha zisuka kwezenyama ziye ekwenziweni kobuhlakani. Isibonelo, ubuchwepheshe be-vivo be-"Object Tracking" bungakhiya ezihlokweni ezinyakazayo futhi bugcine ukugxila, kuyilapho i-AIS ye-Huawei (AI-Shake) ibikezela ama-jitter trajectories ngokufunda komshini. Ngokuzayo, ukwenziwa ngcono kwe-synergistic kwezinzwa nama-chips kuzothuthukisa ukunemba kokumelana nokunyakaziswa kuyilapho kunciphisa ukusetshenziswa kwamandla, kuqhubekisela phambili ukuthwebula izithombe kweselula kumazinga ochwepheshe.

Ukuvela kobuchwepheshe bokulwa nokunyakaziswa kwamaselula kuqhutshwa ngokuyisisekelo isidingo sabasebenzisi sokuthwebula izikhathi zesinema usohambweni." Kungakhathaliseki ukuthi ukwethembeka kwakudala kwe-OIS, ukuguquguquka nokulula kwe-EIS, noma ukusebenza ngempumelelo kwesistimu ehlanganisiwe yama-axis ayisithupha, konke kuthuthukisa umuzwa wezithombe zamaselula ngezilinganiso ezihlukene. Uma ukhetha, kubalulekile ukucabangela isabelomali sakho se-antiriosha kungaba ngempela usizo lokusungula esikhundleni sokuba umkhawulo.
