Pamene chiwonetsero cha LED chikugwiritsidwa ntchito mu chipinda chowongolera, situdiyo ya TV ndi malo ena, nthawi zina zimayambitsa kusokoneza kwa moire pa chithunzi cha kamera.Pepalali likuwonetsa zomwe zimayambitsa ndi mayankho a moire, ndipo imayang'ana momwe mungasankhire chophimba cha LED kuti muchepetse kapena kuchotsa moire.
1.Kodi moire anakhalako bwanji?
2.Kodi kuchotsa kapena kuchepetsa moire?
3.Momwe mungasinthire mawonekedwe a gridi ya CCD kamera ndi chiwonetsero cha LED?
4.Momwe mungasinthire mtengo wachibale wa CCD kamera ndi mawonekedwe a gridi ya LED?
5.Kodi pali njira yosinthira dera lakuda losakhala lowala kukhala lowala pakuwonetsa kwa LED?
Mukajambula zithunzi pazithunzi zowonetsera zamagetsi za LED zikugwira ntchito, mikwingwirima ina yachilendo ndi ma ripples osakhazikika amawonekera.Ma ripples awa amatchedwa moire fringes kapena moire zotsatira.Moire effect ndi malingaliro owoneka.Pamene gulu la mizere kapena mfundo zikuwonetsedwa pamwamba pa gulu lina la mizere kapena mfundo, mizere kapena mfundozi zimakhala zosiyana ndi kukula kwake, ngodya kapena matayala.
Chikoka chachikulu cha zotsatira za Moore ndi kanema wawayilesi ndi kamera.Ngati kuunikira pakati pa ma pixel a skrini yowonetsera zamagetsi ya LED sikuli bwino, mawonekedwe azithunzi pawonekedwe lamagetsi la LED adzakhudzidwa ndipo kunyezimira kudzayamba pomwe chiwonetserochi chimayang'aniridwa bwino.Izi zimabweretsa vuto lalikulu pakupanga ma studio apa TV ndi zida zina zamakanema.
(1) Kodi moire adakhalako bwanji?
Moire:
Pamene mapatani awiri okhala ndi ma frequency a spatial aphatikizana, mawonekedwe ena atsopano nthawi zambiri amapangidwa, omwe nthawi zambiri amatchedwa moire pattern (monga momwe tawonetsera pa Chithunzi 2).
Chowonekera chachikhalidwe cha LED chimakonzedwa ndi ma pixel owala odziyimira pawokha, ndipo pali madera akuda osawoneka bwino pakati pa ma pixel.Nthawi yomweyo, chinthu chodziwikiratu cha kamera ya digito chimakhalanso ndi malo ozindikira ofooka pozindikira kuwala.Pamene kuwonetsera kwa digito ndi kujambula kwa digito kulipo nthawi imodzi, chitsanzo cha moire chimabadwa.
Popeza CCD (chithunzi sensa) chandamale pamwamba (photosensitive pamwamba) ya kamera ndi ofanana ndi chithunzi pakati pa Chithunzi 2, pamene mwambo LED chiwonetsero chazithunzi ndi ofanana ndi chithunzi kumanzere kwa Chithunzi 2. Iwo wapangidwa a machubu otulutsa kuwala kwa lattice okonzedwa molingana.Chiwonetsero chonsecho chili ndi malo akulu osawala, omwe amapanga gululi ngati chitsanzo.Kuphatikizika kwa ziwirizi kumapanga chitsanzo cha moire chofanana ndi kumanja kwa Chithunzi 2.
(2) Momwe mungachotsere kapena kuchepetsa moire?
Popeza mawonekedwe a gululi a LED amalumikizana ndi mawonekedwe a gridi ya CCD kuti apange mawonekedwe a moire, kusintha mtengo wachibale ndi mawonekedwe a gululi amtundu wa grid CCD ndi mawonekedwe a gridi ya LED amatha kuthetsa kapena kuchepetsa mawonekedwe a moire.
(3) Momwe mungasinthire mawonekedwe a grid ya CCD ndi chiwonetsero cha LED?
Pogwiritsa ntchito kujambula filimu, palibe pixel yogawidwa nthawi zonse, kotero palibe mafupipafupi okhazikika komanso opanda moire.
Chifukwa chake, chodabwitsa cha moire ndi vuto lomwe limayambitsidwa ndi digito ya kamera ya TV.Kuti muchotse moire, kusintha kwa chithunzi chazithunzi cha LED chotengedwa mu lens kuyenera kukhala kocheperako poyerekeza ndi ma frequency a chinthu chovuta.Izi zikakwaniritsidwa, palibe malire ofanana ndi a sensa omwe angawonekere pachithunzichi, motero palibe moire omwe angapangidwe.
M'makamera ena a digito, fyuluta yotsika pang'ono imayikidwa kuti isefa gawo lapamwamba la mawonekedwe azithunzi kuti muchepetse moire, koma izi zimachepetsa kuthwa kwa chithunzicho.Makamera ena a digito amagwiritsa ntchito zinthu zozindikira pafupipafupi.
(4) Momwe mungasinthire mtengo wachibale wa CCD ya kamera ndi mawonekedwe a grid yowonetsera LED?
1. Sinthani ngodya yowombera kamera.Potembenuza kamera ndikusintha pang'ono kuwombera kwa kamera, phokoso la moire likhoza kuthetsedwa kapena kuchepetsedwa.
2. Sinthani malo owombera kamera.Mwa kusuntha kamera kumanzere ndi kumanja kapena mmwamba ndi pansi, mukhoza kuthetsa kapena kuchepetsa mole ripple.
3. Sinthani makonda pa kamera.Kuyang'ana ndi tsatanetsatane wambiri zomwe zikuwonekera bwino pazithunzi zatsatanetsatane zitha kupangitsa kuti tinthu tambiri tiphuke.Kusintha pang'ono koyang'ana kungathe kusintha kumveka bwino, motero kumathandiza kuthetsa ma ripples.
4. Sinthani kutalika kwa lens.Ma lens osiyanasiyana kapena zoikamo zautali wokhazikika zitha kugwiritsidwa ntchito kuthetsa kapena kuchepetsa ma molar ripple.
Chowonetsera chowonetsera cha LED chimakonzedwa ndi ma pixel owala odziyimira pawokha, ndipo pali madera akuda osawoneka bwino pakati pa ma pixel.Pezani njira yosinthira dera lakuda losakhala lowala kukhala lowala, ndikuchepetsa kusiyana kowala ndi ma pixel owala odziyimira pawokha, omwe amatha kuchepetsa kapena kuchotseratu moire.
(5) Kodi pali njira yosinthira dera lakuda losakhala lowala kukhala lowala pakuwonetsa kwa LED?
COB ma CD ma CD chiwonetsero cha LED, ndikosavuta kuchita izi.Ngati tili ndi mwayi woyika chiwonetsero cha LED cha COB pamodzi ndi chiwonetsero cha LED cha SMD, titha kupeza mosavuta kuti: chiwonetsero cha LED cha COB chimatulutsa kuwala kofewa ngati gwero la kuwala pamwamba, pomwe chiwonetsero cha LED cha SMD mwachiwonekere chimamva kuti zowala particles ndi palokha zounikira mfundo.Zitha kuwoneka kuchokera pa Chithunzi 3 kuti njira yosindikizira ya COB yonyamula ndi yosiyana kwambiri ndi ya SMD.Njira yosindikizira yakuyika kwa COB ndiye gawo lonse lotulutsa kuwala kwa ma pixel ambiri otulutsa kuwala palimodzi.Njira yosindikizira yakuyika kwa SMD ndi pixel yowala imodzi, yomwe ndi malo odziyimira pawokha.
MPLED ikhoza kukupatsirani chiwonetsero cha LED cha COB ma CD ma CD, ndipo zinthu zathu za ST Pro zitha kupereka mayankho otere.Chowonetsera chowonetsera cha LED chomalizidwa ndi kuyika kwa cob chili ndi malo ang'onoang'ono, omveka bwino komanso owoneka bwino kwambiri.Chip chotulutsa kuwala chimayikidwa mwachindunji pa bolodi la PCB, ndipo kutentha kumamwazikana mwachindunji kudzera pa bolodi.Mtengo wotsutsa kutentha ndi wochepa, ndipo kutentha kwa kutentha kumakhala kolimba.Kuwala pamwamba kumatulutsa kuwala.Kuwoneka bwino.
Kutsiliza: Momwe mungachotsere kapena kuchepetsa moire pakuwonetsa kwa LED?
1. Sinthani ngodya yojambulira kamera, malo, makonda ndi kutalika kwa lens.
2. Gwiritsani ntchito kamera ya kanema yachikhalidwe, kamera ya digito yokhala ndi sensa yapamwamba kwambiri ya malo, kapena kamera ya digito yokhala ndi fyuluta yotsika.
3. Chowonetsera chowonetsera cha LED mu mawonekedwe a COB a phukusi amasankhidwa.
