Ndi kupita patsogolo kosalekeza kwa sayansi ndi ukadaulo, kuwala kochepa kwa LEDchiwonetseroamagwiritsidwa ntchito kwambiri pamsika. Zokhala ndi matanthauzo apamwamba, kuwala kwakukulu, kuchulukira kwakukulu komanso kutsitsimula kwapamwamba, kuwala kwa LED kakang'onochiwonetseros amagwiritsidwa ntchito kwambiri m'makoma a TV, kumbuyo kwa siteji, malonda ndi zipinda zamisonkhano. Kutanthauzira kwakukulu komanso kuphatikizika kosasunthika kwa ma LED ang'onoang'onochiwonetseroziyenera kukhala ndi purosesa yabwino yamavidiyo. Munkhaniyi, tikuwonetsa matekinoloje ofunikira a 8 a LED yaying'onochiwonetserokanema purosesa.
1. Technology Space Conversion Technology
LEDchiwonetseroUkadaulo wa kutembenuza danga ndi imodzi mwamakina ofunikira a purosesa ya kanema. Zowonetsera zosiyana za LED zimagwiritsa ntchito malo osiyanasiyana amitundu, choncho m'pofunika kutembenuza chizindikiro cholowera kukhala malo amtundu omwe amafanana ndi chinsalu cha LED pogwiritsa ntchito luso la kutembenuza danga. Pakalipano, malo omwe amagwiritsidwa ntchito kwambiri ndi RGB, YUV ndi YCbCr, ndi zina zotero. Kupyolera mu luso la kutembenuza danga, malo awa amatha kusinthidwa kukhala malo amtundu wa chophimba cha LED, kuti akwaniritse kubereka kolondola kwa utoto.
2. Ukadaulo Wokulitsa Zithunzi
Kusamvana kwa chophimba chaching'ono cha LED ndikokwera kwambiri, ndipo ukadaulo wokulitsa zithunzi ndi imodzi mwamaukadaulo ofunikira a purosesa yamavidiyo. Tekinoloje yokulitsa zithunzi imaphatikizanso ma algorithm otanthauzira, magnification algorithm ndi edge preservation algorithm. Interpolation algorithm ndi imodzi mwaukadaulo womwe umagwiritsidwa ntchito kwambiri pakukulitsa zithunzi, kudzera mu interpolation aligorivimu ikhoza kukhala chithunzi chotsika mpaka kukulitsa chithunzithunzi chapamwamba, kuwongolera kumveka bwino komanso tsatanetsatane wa chithunzicho.
3.Color Correction Technology
Ukadaulo wowongolera utoto ndiukadaulo wofunikira kwambiri mu purosesa ya kanema wa LED, chifukwa chophimba cha LED mukupanga chiziwoneka choyipa cha chromatic, makamaka mu splicing ndizovuta kwambiri kusinthika kwa chromatic. Ukadaulo wowongolera utoto umatengera kusiyanitsa, machulukitsidwe, hue ndi magawo ena amasinthidwa kuti akwaniritse bwino komanso kufananiza, kusintha utoto wa kanemayo.
4. Gray Scale Processing Technology
Small phula LED chophimba kuwonetsera imvi sikelo ndi mkulu kwambiri, kotero grayscale processing luso ndi imodzi mwa matekinoloje kiyi mu kanema purosesa. Ukadaulo wa Grey Scale processing makamaka kudzera muukadaulo wa PWM (Pulse Width Modulation) wowongolera kuwala kwa LED, kuti kuwala kwa LED iliyonse kusinthidwa bwino. Nthawi yomweyo, ukadaulo wopangira imvi umafunikanso kuthana ndi vuto la kuchuluka kwa milingo yotuwa kuti akwaniritse chiwonetsero chatsatanetsatane.
5. Pretreatment Technology
Ukadaulo wokonzekeratu umatanthawuza kukonza ndi kukhathamiritsa kwa siginecha yamakanema pamaso pa chiwonetsero cha LED. Zimaphatikizaponso kupindula kwa ma sign, denoising, kunola, kusefa, kukulitsa mtundu ndi njira zina zopangira. Mankhwalawa amatha kuchepetsa phokoso, kupititsa patsogolo kusiyana ndi kumveka bwino potumiza zizindikiro, komanso kuthetsa kusiyana kwa mitundu ndikuwongolera zenizeni ndi kuwerenga kwa zithunzi.
6. Kulumikizana kwa chimango
Powonetsera chophimba cha LED, ukadaulo wolumikizana ndi chimango ndi imodzi mwamaukadaulo ofunikira kwambiri pakupanga makanema. Ukadaulo wolumikizana ndi chimango umatheka makamaka powongolera kuchuluka kwa zotsitsimutsa za chophimba cha LED ndi mawonekedwe amtundu wa siginecha yolowera, kuti vidiyoyo iwonetsedwe bwino. Mu kuphatikizika kwamitundu yambiri, ukadaulo wolumikizira chimango umatha kupewa kugawanika kwa chinsalu ndikung'ambika ndi zovuta zina.
7.Kuwonetsa Kuchedwa Technology
Nthawi yochedwa yowonetsera yazithunzi zazing'ono za LED ndizofunika kwambiri chifukwa muzinthu zina, monga mpikisano wa E-Sports ndi makonsati, kuchedwa kwa nthawi yaitali kungapangitse kuti kanema ndi audio zisagwirizane, zomwe zimakhudza zomwe wogwiritsa ntchito akukumana nazo. Chifukwa chake, mapurosesa amakanema amayenera kukhala ndi ukadaulo wochedwa kuti akwaniritse nthawi yayifupi kwambiri yochedwetsa.
8.Multi-signal Input Technology
Nthawi zina, ndikofunikira kuwonetsa magwero angapo nthawi imodzi, monga makamera angapo, makompyuta angapo ndi zina zotero. Choncho, pulosesa ya kanema imayenera kukhala ndi teknoloji yolowetsa zizindikiro zambiri, zomwe zimatha kulandira magwero angapo a zizindikiro panthawi imodzi, ndikusintha ndi kusakaniza mawonetsero. Panthawi imodzimodziyo, teknoloji yolowetsa zizindikiro zambiri imayeneranso kuthetsa mavuto a magwero osiyanasiyana a magwero a zizindikiro ndi mitengo yosiyana ya chimango kuti akwaniritse mavidiyo okhazikika komanso osalala.
Mwachidule, matekinoloje ofunikira a purosesa yaying'ono ya vidiyo ya LED akuphatikiza ukadaulo wosinthira danga, ukadaulo wokulitsa zithunzi, ukadaulo wowongolera utoto, ukadaulo wopangira imvi, ukadaulo wolumikizana ndi chimango, ukadaulo wochedwetsa komanso ukadaulo wolowetsa ma sign-ambiri. Kugwiritsa ntchito matekinolojewa kumatha kusintha bwino mawonekedwe owonetsera komanso chidziwitso cha ogwiritsa ntchito pazithunzi zazing'ono za LED. M'tsogolomu, ndi chitukuko chosalekeza cha teknoloji, pulosesa ya kanema idzasinthidwa nthawi zonse ndikusinthidwa kuti igwiritse ntchito chophimba chaching'ono cha LED kuti chibweretse ntchito yabwino kwambiri.
