Kwadalwa ngo 05.07
I. Isingeniso
Izithombe zendabuko zidinga abasebenzisi ukuba baphawule iphuzu lokugxila ngaphambi kokuthatha isithombe. Uma isithombe sithathwe, ukugxila kuqinisekisiwe, kushiya akukho ndawo yokulungisa. Lokhu kunciphisa ukusebenza kwazo ezimeni lapho isihloko sishintsha ngokushesha noma lapho ukugxila okufunwayo kushintsha ngemuva kokuthathwa, njengokuthatha izithombe zezenzo noma ukuhamba endaweni eshintshashintshayo enezendlalelo eziningi zokujula. Lokhu futhi kwenza kube nzima ukufinyelela ukugxila okuphelele ezimeni zokukhanya okuphansi noma uma isihloko sitholakala kancane.
1.2 Iintroducing the Light Field Camera Module
Ibhokisi lemidlalo yokukhanya limele ukuhamba phambili okukhulu emnothweni wezithombe. Iphula izithiyo zendabuko ngokuthwebula hhayi kuphela amandla kodwa futhi nendlela yokukhanya, ivumela ukulungiswa kokugxila ngemva kokuthwebula. Le msebenzi emangalisayo ivumela abasebenzisi ukuthi bashintshe iphuzu lokugxila ngemuva kokuthathwa kwesithombe, njengokuthi babe namandla okuphinda baphinde bakhethe indawo yokugxila ehlukile.
II. Iziqinisekiso Zobuchwepheshe beMojula yeKhamera yeMithombo Yokukhanya
2.1 Ukuthwebula Nokurekhoda Ulwazi Lwezibani
Ihlo lekhasi lekhanda lekhanda lisebenzisa indlela ehlukile yokuthola ulwazi lokukhanya. Inezici ezihlukile ezincane ezibekwe phakathi kwe-lens enkulu nesensori. Lapho ukukhanya kungena emoduleni, ama-lens amancane ahlukanisa imisebe evela ezindaweni ezahlukene. I-lens ngayinye ikhipha ukukhanya endaweni ethile yesensori, ibamba kokubili amandla nokuhamba kokukhanya. Le datha ibhalwa njengemkhakha we-4D wokukhanya, enezixhumanisi ezikhombisa indawo nokuhamba kwemisebe yokukhanya, ivumela imodyuli ukuthi igcine imephu ebanzi ye-mkhakha wokukhanya wesigcawu.
2.2 Micro Lens Array Design
Ishlobo lens array iyingxenye ebalulekile kumoduli yekhamera ye-light field. Iqukethe ama-lens amancane amaningi ahlale eduze. I-lens ngayinye isebenza njengohlelo lokuthwebula oluncane, ithwebula ingxenye yesigcawu ukusuka kokuthile. Ngokwenza kanjalo, i-array iqoqe ukukhanya okuvela ezindaweni ezahlukene, ikakhulukazi ithwebula i-light field. Lo mkhono uqinisekisa ukuthi lapho ukukhanya kudlula, kuhlukaniswe ngokwendawo futhi kugxilwe ku-sensor, kuthuthukisa ukuthwebula kolwazi olunembile lokukhanya olubalulekile ekucubunguleni ngemva kokuthwebula nasekulungiseni ukugxila.
2.3 Isithombe Sokwakha Ialgorithimi
Ukuze kwakhiwe izithombe ezineziqondiso ezihlukene, imodyuli ithembele kumasu ahlakaniphile. Enye indlela evamile ibandakanya ukusebenzisa idatha ye-4D light field ethathwe ukuze kudalwe i-virtual pinhole array. Ngokwenza imifanekiso yezikhala ezihlukene ze-pinhole, i-algorithm ingashintsha kahle ibanga lokugxila. Iphatha ama-ray okukhanya athathwe ngalinye i-micro lens, ihlanganisa ulwazi oluvela ezikhathini eziningi ukuze ikhiqize isithombe esisha esinefokali efunwayo. Le nqubo ibandakanya ukubalwa okuyinkimbinkimbi ukuze kubhekwane nesixhumanisi nesivinini sama-ray okukhanya, kuqinisekisa ukuthi isithombe esakhiwe sikhanya futhi sinezincazelo ezicacile endaweni egxilile.
III. Ukuqhathanisa Nezithombe Zendabuko
3.1 Izinqumo Zobuchwepheshe

Hierdie fundamentele verskil stel ligveld kameras in staat om meer buigsame beeldvorming vermoëns te bied.
3.2 Iziphumo Zokufanekisa Zihluke
Ngokuphathelene nemiphumela yokukhanyisa, amakhamera ajwayelekile akhiqiza izithombe ezinefokushi eqinile, kuyilapho amakhamera we-light field engakha izithombe ezinefokushi elungisekayo, okuvumela ukulawula okujulile kokuphuma nokukwazi ukushintsha ifokushi ngemuva kokuthwebula. Lokhu kuholela ezithombeni ezihamba phambili nezihlukahlukene ezingakwazi ukubamba kahle izigcawu eziyinkimbinkimbi ezineziqongo eziningi.
IV. Izicelo kanye Nezinzuzo
4.1 Fotografi
Ngekhono lokukhanya, abathwebuli bezithombe bangakwazi ukulungisa ukugxila ngokukhululeka ngemuva kokuthwebula, bethwebula yonke imininingwane ezindaweni eziyinkimbinkimbi futhi bethuthukisa ubuciko ekuthwebuleni izithombe zephrofayela, izithombe zemvelo, nezithombe ezincane.
4.2 Ividiyo Yokuthwebula
Mu vidiyo yokuqopha, imodyuli yekhamera ye-light field inikeza ukulawula okuqondile kokujula kokubuka. Ivumela ukushintsha kokugxila okuthambile futhi igcina ukujula ezimeni ezishintshashintshayo, ivumela abaqophi bevidiyo ukuba bakhe ama-video ahlaba umxhwele anezinhloso zokugxila ezisezingeni le-professional.
4.3 Iziqhamo neZithombe ezikhulayo
Ihamba lekhanda lekhanda ibamba indima ebalulekile emhlabeni we-virtual kanye ne-augmented reality. Ngokuthwebula idatha ye-light field enembile, isiza ukudala ama-3D models anembile kanye nezindawo ezijulile, kuthuthukisa ulwazi lomsebenzisi ezinhlelweni ze-XR.
V. UkuThuthukiswa Isimo kanye Nezindlela Zesikhathi Esizayo
5.1 Ikhono Lokusebenza Lamanje
Okwamanje, ubuchwepheshe bekhamera be-light field busetshenziswa kakhulu emithonjeni yokuthwebula, emhlabeni we-virtual reality, nasezithombeni zezimboni. Busetshenziswa ukuze kuthathwe izithombe ezisezingeni eliphezulu ezine-adjustment yokugxila esheshayo nokwakha okuhlangenwe nakho kwe-VR okujabulisayo.
5.2 Iinkampani ezinkulu
Lytro, a pioneer in light field technology, has developed innovative light field cameras. NVIDIA, with its research in computational photography, is also active in this field.

5.4 Iinkqubo zeMveliso ezizayo
Mu zikhala zikhala, makhamera a maphunziro a kuwala adzakhala osavuta kugula komanso akhazikitsidwa mu mafoni ndi makamera, kukhululukira ogwiritsa ntchito osavuta kuti akhale ndi mwayi wosinthira kuthekera kwa chithunzi pambuyo pa kutenga. Mu mafakitale, adzagwiritsidwa ntchito pa kasamalidwe ka khalidwe, kupanga 3D, ndi kuwona kwa makina, kukulitsa kuchita bwino ndi kuchita bwino.
VI. Isiphetho
6.1 Isishwankathelo
Iyi ngingo ikora mu moduli y'ifoto y'urumuri, isuzuma uburyo bwayo bwihariye bwo guhindura fokus nyuma yo gufata ifoto, amahame y'ubuhanga, imikoreshereze, status y'iterambere, n'uburyo bwo kunoza SEO, igaragaza ubushobozi bwayo bwo guhindura isura y'ifoto.
6.2 Isikhumbuzo Sokwenza
Uma ungathokoziswa ngamakhono e-module yekhamera ye-light field, hlola ngokujulile ngokuyisebenzisa ezithombeni, ividiyo, noma emaphrojeni e-VR. Yabelana ngathola zakho kanye nezinto ozihlangabezana nazo ukuze uthuthukise ukuqonda nokusetshenziswa kwale teknoloji entsha.
