Global Shutter VS Rolling Shutter

Kodi mukudabwa momwe mungasankhire pakati pa Rolling shutter ndiChotsekera padziko lonse lapansiza pempho lanu?Kenako, werengani nkhaniyi kuti mumvetse bwino kusiyana pakati pa shutter ndi shutter yapadziko lonse komanso momwe mungasankhire yomwe ikugwirizana bwino ndi pulogalamu yanu.

Makamera am'mafakitale amasiku ano ndi makina ojambulira ali ndi masensa omwe amajambula ndi kujambula zithunzi pazolinga zosiyanasiyana za kukonza ndi kusanthula.Masensa amenewa amagwiritsa ntchito shutter yamagetsi kujambula zithunzi.Chotsekera chamagetsi ndi chipangizo chomwe chimayang'anira kuwonekera kwa zitsime za photon pa sensa.Imatsimikiziranso ngati ma pixel amawululidwa mzere ndi mzere kapena ngati matrix wathunthu.Mitundu iwiri yayikulu ya shutter yamagetsi ndi Rolling shutter ndi Global shutter.Nkhaniyi ikuyang'ana makina otsekera, kusiyana pakati pa zotsekera ziwirizi, ndi komwe angawagwiritse ntchito.

Kodi Rolling shutter ndi chiyani?

Makina otsekera mu kamera amawulula mizere ya pixel imodzi pambuyo pa inzake, ndikuchotsa kwakanthawi kuchokera pamzere umodzi kupita wina.Poyamba, mzere wapamwamba wa chithunzicho umayamba kusonkhanitsa kuwala ndikumaliza.Kenako mzere wotsatira umayamba kutolera kuwala.Izi zimapangitsa kuchedwa kumapeto ndi nthawi yoyambira kusonkhanitsa kuwala kwa mizere yotsatizana.Nthawi yosonkhanitsa kuwala kwa mzere uliwonse ndi yofanana ndendende.

Rolling Shutter Effect

Kusiyana kwamaganizidwe pakati pa sensa yotsekera yotsekera ndi sensor yapadziko lonse lapansi kumawonekera makamaka pakupeza zithunzi zamphamvu.Zinthu zoyenda mwachangu zikagwidwa ndi sensa yotsekera, chotchinga chotchinga Mphamvu chimachitika.Mu shutter yotsekera, ma pixel onse amtundu wa sensa yazithunzi samawululidwa nthawi imodzi ndipo mzere uliwonse wa ma pixel a sensor amawunikidwa motsatizana.Chifukwa cha izi, ngati chinthu chikuyenda mwachangu kuposa nthawi yowonekera komanso nthawi yowerengera ya sensa ya chithunzi, chithunzicho chimasokonekera chifukwa cha mawonekedwe a kuwala.Izi zimatchedwa rolling shutter effect.

Kodi Global Shutter ndi chiyani?

Chotsekera padziko lonse lapansiMawonekedwe a sensa yazithunzi amalola ma pixel onse a sensa kuti ayambe kuwonekera ndikusiya kuwonekera nthawi imodzi pa nthawi yowonekera panthawi yomwe chithunzi chilichonse chikupezeka.Pambuyo pakutha kwa nthawi yowonetsera, kuwerengera kwa pixel kumayamba ndikupitilira mzere ndi mzere mpaka zonse za pixel zitawerengedwa.Izi zimapanga zithunzi zosasokonezeka popanda kugwedezeka kapena kugwedezeka.Masensa a shutter padziko lonse amagwiritsidwa ntchito kujambula zinthu zothamanga kwambiri.

Kodi sensor yapadziko lonse lapansi imagwira ntchito bwanji?

Chotsekera chapadziko lonse chimawulula mizere yonse ya chithunzi nthawi imodzi, 'kuzizira' chinthu chomwe chikuyenda.Izi zimalepheretsa kupotoza, zomwe zimapangitsa ukadaulo wa shutter wapadziko lonse lapansi kukhala chisankho choyenera pamapulogalamu omwe ali ndi zinthu zosuntha komanso kusuntha kwachangu, kuphatikiza kuzindikira kwa nambala yamalaise ngati gawo lowunika magalimoto, mwachitsanzo.

Ubwino wa ma sensor a shutter padziko lonse lapansi:

1. High chimango mitengo

2. Kusamvana kwakukulu

3. Zithunzi zowoneka bwino za Crystal, ngakhale zowonekera zazifupi kwambiri

4. Makhalidwe apamwamba a phokoso, ngakhale m'malo osawunikira bwino

5. Broad dynamic range

6. Kuchita bwino kwambiri mpaka 70%

Kodi timafuna kuti kamera yapadziko lonse lapansi yotseka ndi kamera yotsekera?

Kamera ya shutter yapadziko lonse imagwiritsidwa ntchito kwambiri kujambula zinthu zothamanga kwambiri popanda zinthu zakale komanso zowoneka bwino.Makamera otsekera padziko lonse lapansi amagwiritsidwa ntchito ngati kutsatira mpira, makina opanga mafakitale, maloboti osungira, ma drones ndi zina.

Masensa otsekera otsekera amapereka chidwi kwambiri pakujambula ndipo atha kugwiritsidwa ntchito ngati ntchito zotsika mtengo.Amagwiritsidwa ntchito kwambiri kujambula zinthu zomwe zikuyenda pang'onopang'ono monga mathirakitala aulimi, zotengera zoyenda pang'onopang'ono, ndi ntchito zodziyimira zokha monga ma kiosks, scanner barcode, etc.
