An Kira ISP (Image Signal Processor)? Suna, wani haifuwa, kuma importance

Sun ake soya shafi ne yanzu a cikin kasa da wani aiki, amma hanyar wannan suna shafi da aka yi daga farawaƙi jihar rubutu ko lokacin dai dai na kamera ta hanyar mataki, suna aiki mahaifi a ke nuna.

Samfari daidai (ISP) ya ci gaskiya don hanyar shafi. Ya ne alatun mahaifi mai tsaye da ya fi saita data na wannan shafi dai dai a cikin wannan shafi. Akwai yanzu samfari daidai na samfari ake yi? Ko bayan samfari? Suna aiki na samfari don wannan teknoloji a cikin wannan rubutun.

An yi Samfari Daidai (ISP)?

Samfari daidai, ko ISP na farko, ya ne komoponan mai gabatarwa a cikin rubutun jihar rubutu, webkam, kamera digital, da wata aikin samfari. isp a kamera wakilin shugaban yana zuwa aikacewa daidai da rawaƙaɗen fayilka kuma yi amfani da alamar daidai na biyu a cikin smartphone, camera digital, kuma wata abubuwan daga cikin alamar complex algorithms kuma techniques talaka'a signal processing don tabbatar parametar daidai na bayanin fayilka tomutum, contrast, kuma color balance.

Yi abin da ke? sunan kuma wakilin shugaban ISP?

ISP ya kamata wannan abubuwan daidai don samun bayanin fayilka daidai, noise-free images. Samun wani haifuwar wadannan architecture kuma wakilin shugaban ISP ya yi amfani da hanyar daidai na bayanin fayilka.
Hanyar na ISP ya kamata wannan abubuwan daidai:

• A/D Converter: Don samun bayanin analog kuma da image sensor ya yi amfani da digital signals, don taimaka da foundation don amfani daidai na bayanin fayilka.
• Digital Signal Processor: Don samun complex algorithms don tabbatarshe bayanin fayilka.
• Memory Unit: don zama raw image data kuma intermediate results of processing.

Za'a suka yi a cikin shugun daidaita, amma an kira daidai:

• Taswira daidai: Tashe ne da fatan ta fiye mai tsarin tatsuniya daga rubutu na pixel ake so da yin taimaka daidai na fitarci. Zobba suka iya alamar daidaita biyu a cikin hanyar kara da kuma baya da wannan.
• Kullum Littafin: Babban littafin da ke gabatarwa da hanyar gida da sensor, suna littafi ba shi ne daidai. Sensor na rubutu na littafi ya iya bincika littafi don sauka a cikin wani haifuwar daidai da kula da fadiffa na littafi.
• Kara Daidaita da Fokus Daiddaita: A cikin isp camera ya iya karar daidaita da fokus daidaita optimali a cikin bayyana rayuwar hanyar gida, ya baya da adjustar daidai.
• Taimakawa kawai: Taimaka kulauna an jiru aiki mai tsarin daidai daga cikin wannan suna daidai, amma idan ka yi shi a kan rubutu na rangin, ya sosai ranarwa. ISP camera yana sona automatically correct temperature na rangin don hanyar daidai na abubuwan kulauna a cikin samarun tattabara.
• Demosaicing: Binciken image processors suka iya yi aikin Bayer filter color array na red, green and blue. Binciken yana kasance missing color information biyu de-mosaicing algorithm don restor ranarwa full-color and enhance detail na ranarwa da colors na ranarwa.
• image compression: yanuwar file size and optimizes storage and transmission efficiency ko ba shi sosai image quality.

An yi bincike image processing?

Image processing shekarar complex design don alamar daidai a cikin algorithms for processing digital images. Work flow-ko suna collection na refined operations don ensure efficient and high quality conversion of image data. an yi bincike image sensor?
Kuna daidai halinin daga cikin aikacewa na rubutu:

1. Taimakon Data Da Aikacewa: ISP yan uwar sensors ta taimako data raw daga cikin wani scene da ake aikacewa signal analog zuwa signal digital biyu A/D aikacewa.
2. Aikacewa Sabon Ruwa: ISP an shaƙe irayen rubutu don karaƙe wannan iraye, amfani da feature extraction da analysis na rubutu, da aka gabatar da irayen don mutum mai amfani da features, aka samfuka information na features, da aka yi analysis da information na features don aikacewa recognition object da scene matching. Daga cikin wannan, ya kasance masu recognition na face da authentication na fingerprint.
3. Aikacewa Core: ISP an yi reduction noise, correction color, da adjustment don labarar image quality. An bata da image yana optimal daga cikin colors, brightness, da clarity.
4. Aikacewa Advanced: Ana amfani da techniqes na optimization na image ma’ana de-mosaicing, gamma correction, da akwatin da aka samun details na image da consistency visual.
5. Optimization Final Da Output: Kayan fayil ta taimakawa daya wara kammalƙwar shafi, don hanyar a cikin saukarwa da rubutu a yi amfani da wannan daga shafi, da aka samun rubutu wanda yana jihar gaskiya.

Jinsi da ni ISPs

Sunan biyu jinsi na mai alamna ISP:

• ISP Internal: Saiyan alamarwa na image signal processor yana fiye a cikin sensor rubutu, da aka samun abubuwan alamarwa. An yi amfani da shi a cikin kamiran kamera na karatu kuma kan kewaye. ISPs internal yana binciken kalmar rubutu da alamarwa, kuma yana kewaye da anfani ba ake amfani.
