Dab tsi yog qhov txawv ntawm 720P, 960P, 1080P, 4K?Hauv tsab xov xwm no, kuv yuav sim piav qhia qee cov ntsiab lus tseem ceeb txog kev daws teeb meem, vam tias yuav pab peb cov neeg nyeem nkag siab lub koob yees duab daws teeb meem zoo dua.

Ua ntej,qhov kev daws teeb meem ntawm lub koob yees duab
Feem ntau yog hais txog kab rov tav kev daws teeb meem, tshwj tsis yog tias "ntug" tau teev tseg.Qhov taw qhia rau kev ntsuas qhov kev daws teeb meem ntawm lub koob yees duab yog qhov kev daws teeb meem kab rov tav, thiab nws chav tsev yog ib khub kab, uas yog, nws tuaj yeem muab faib ua Tus lej ntawm cov kab dub thiab dawb kab uas tuaj yeem txheeb xyuas tau.Feem ntau siv cov koob yees duab dub-thiab-dawb feem ntau muaj kev daws teeb meem ntawm 380-600, thiab cov kev daws teeb meem xim ntawm 330-540.Qhov loj dua tus nqi, qhov pom tseeb dua.

 

2. Pixels

Pixels yog ib qho kev qhia ntawm lub koob yees duab daws teeb meem.Tab sis ua ntej ntawm tag nrho cov, peb yuav tsum to taub hais tias lub pixels ntawm lub koob yees duab muab faib ua: zoo li qub pixels thiab dynamic pixels.Yog hais tias tus qauv-txhais lub koob yees duab yog ntsuas ntawm 3 lab pixels, nws yuav tsum tau muab sau tseg. hais tias qhov no yog cov duab tseem ceeb, thiab siv tsis tau rau kev yees duab.Koj yuav tsum tau saib ntawm qhov thib ob parameter, 500,000 dynamic pixels,
Qhov no yog tus naj npawb ntawm pixels muaj rau kev tua.

 

3. Kev daws teeb meem thiab pixels

Kev daws teeb meem suav nrog ob qho tib si kab rov tav thiab ntsug cov lus qhia, thiab yog qhov ntsuas ntawm qhov pom tseeb Feem ntau sharpness thiab pixels zoo ib yam.
Piv txwv li, SD, koj tuaj yeem muab 720 los ntawm 576, thiab koj tuaj yeem pom tias qhov tshwm sim yog dab tsi.thiab nominal
Lub dynamic pixel qhov tseem ceeb yog ze heev.Pixels sawv cev rau lub koob yees duab lub peev xwm tua, thaum kev daws teeb meem yog lub koob yees duab lub peev xwm kaw.Qhov ob yuav tsum yog tias tus nqi dynamic pixel ntau dua li qhov txhais.
