Momwe Mungathetsere kapena Kuchepetsa Kuwala kwa Moire kwa Kuwonetsera kwa LED?

Pamene mawonedwe otsogolera amagwiritsidwa ntchito muzipinda zolamulira, ma studio a TV ndi malo ena, moire nthawi zina amapezeka.Nkhaniyi ifotokoza zomwe zimayambitsa ndi njira zothetsera moire.

Zowonetsera za LED pang'onopang'ono zakhala zida zowonetsera zipinda zowongolera ndi ma studio apa TV.Komabe, panthawi yogwiritsira ntchito, zidzapezeka kuti pamene lens ya kamera ikuyang'ana pa chiwonetsero chotsogoleredwa, nthawi zina padzakhala mikwingwirima ngati mafunde amadzi ndi mitundu yachilendo (monga momwe tawonetsera pa Chithunzi 1), yomwe nthawi zambiri imatchedwa chitsanzo cha Moire.

Chithunzi 1

Kodi mitundu ya moire imabwera bwanji?

Pamene mapatani awiri okhala ndi ma frequency apakati aphatikizana, mtundu wina watsopano umapangidwa nthawi zambiri, womwe umatchedwa moire (monga momwe tawonetsera pa Chithunzi 2).

Chithunzi 2

Chiwonetsero chachikhalidwe cha LED chimapangidwa ndi ma pixel odziyimira pawokha otulutsa kuwala, ndipo pali madera owoneka bwino osatulutsa kuwala pakati pa ma pixel.Pa nthawi yomweyo, zinthu photosensitive makamera digito komanso zoonekeratu ofooka photosensitive madera pamene iwo tcheru.Moire adabadwa pomwe chiwonetsero cha digito ndi kujambula kwa digito kunalipo.

Momwe mungachotsere kapena kuchepetsa Moire?

Popeza kugwirizana pakati pa mawonekedwe a gridi ya chiwonetsero cha LED ndi mawonekedwe a gululi a CCD kamera kumapanga Moire, kusintha mtengo wachibale ndi mawonekedwe a gululi a CCD kamera ndi mawonekedwe a gululi a chiwonetsero cha LED akhoza mwapang'onopang'ono. kuthetsa kapena kuchepetsa Moire.

Momwe mungasinthire mawonekedwe a gridi ya CCD ndi kameraChiwonetsero cha LED?

Pojambula zithunzi pafilimu, palibe ma pixel omwe amagawidwa nthawi zonse, kotero palibe mafupipafupi okhazikika a malo ndipo palibe moire.

Chifukwa chake, chodabwitsa cha moire ndi vuto lomwe limabweretsedwa ndi digito yamakamera a TV.Kuti athetse moire, kusintha kwa chithunzi cha LED chojambulidwa mu lens chiyenera kukhala chochepa kwambiri kusiyana ndi mafupipafupi a malo a photosensitive element.Izi zikakwaniritsidwa, sizingatheke kuti mikwingwirima yofanana ndi chithunzithunzi iwonekere pachithunzichi, ndipo sipadzakhala moire.

Pofuna kuchepetsa moire, makamera ena adijito ali ndi fyuluta yotsika pang'ono kuti asefe mbali zapamwamba zapafupipafupi pachithunzichi, koma izi zichepetsa kuthwa kwa chithunzicho.Makamera ena a digito amagwiritsa ntchito masensa okhala ndi ma frequency apamwamba kwambiri.

Momwe mungasinthire mtengo wachibale wa mawonekedwe a gridi ya CCD kamera ndi chophimba cha LED?

1. Sinthani ngodya ya kamera.Moire ikhoza kuthetsedwa kapena kuchepetsedwa potembenuza kamera ndikusintha pang'ono mbali ya kamera.

2. Sinthani malo owombera kamera.Moire ikhoza kuthetsedwa kapena kuchepetsedwa posuntha kamera kumbali kapena mmwamba ndi pansi.

3. Sinthani makonda pa kamera.Kuyang'ana kwambiri komanso tsatanetsatane wambiri pamapangidwe atsatanetsatane kumatha kuyambitsa moire, ndipo kusintha koyang'ana pang'ono kumatha kusintha makulidwe ake ndikuchotsa moire.

4. Sinthani kutalika kwa lens.Mitundu yosiyanasiyana ya ma lens kapena utali wokhazikika angagwiritsidwe ntchito kuthetsa kapena kuchepetsa moire.
