CCD vs. CMOS image sensors: Wannan shi ne ya kamata ta hanyar wannan?

May 20, 2024

Is CCD more sensitive than CMOS

A cikin teku na haske, nau'i biyu na kayan aikin jin kai anabata da aka samu su zama mafi kyau - CCD da CMOS. Waɗannan fasahohin suna ba mu damar ganin komai. Amma, lokacin da muka ci karo da waɗannan fasahohin biyu, ba za mu iya guje wa tambayar wanne daga cikinsu ne mafi jin kai, CCD ko CMOS.

Gudun hanyoyi na CCD da CMOS

Kuna fi kwana suna, amma kan mutum gaskiya, yanzu anabanci kuma wane haɗin nan sensar fayeye suna aiki bisa ga ka'idarsu da halayensu. CCD (Na'urar Haɗin Wutar Lantarki) da CMOS (Na'urar Semiconductors na Oxide na Metal na Musamman) na'urori ne da ke canza haske zuwa sigina na lantarki Wanne wanda ke haifar da hotuna da mutane za su iya fassara. Duk da haka, suna aiki kawai kodayake burinsu suna da kama.

Wannan tsari an yi uso yana buƙatar ƙarfin wuta mai yawa da  ya yana samar da hotuna masu inganci sosai tare da kawai daidai matakan hayaniya, ba kamar sauran abubuwa ba.

A gefe guda, na'urorin CMOS suna wucewa ta cikin tsari mai sauƙi don canza haske zuwa sigina na lantarki. Kowanne pixel yana da mai canza cajin sa Wanne yana ba da damar na'urorin CMOS su sarrafa hotuna cikin sauri fiye da abokan aikinsu; duk da haka, wannan kuma yana zuwa tare da rashin fa'ida daga cikin kamar matakan hayaniya mafi girma da rage ingancin hoto.

Bayanin da Fadacin CCD

An san CCD sensors da suna bayar da ingantaccen ingancin hoto da kuma kasancewa masu matukar jin kai. Suna da babban resolution sosai wanda suna ba da da shawo mai kwayoyi da hotuna masu haske tare da launuka da suka bayyana fiye da yadda aka saba. Duk da haka, suna amfani da a cikin wannan suna energy compared to wadanda suka fi arha kamar wadanda aka yi da kayan haɗin ƙarfe na oxide.

Bayanin da Fadacin CMOS

CMOS sensors suna da ƙananan kudin naiwa,  da  ƙarancin amfani da wutar lantarki idan aka kwatanta da tsofaffin CCDs da wani shi fa'idodin haɗin kai fiye da su daukawa su ne zaɓin sensor a cikin aikace-aikace da yawa kamar wayoyin salula da na'urorin ɗaukar hoto. Duk da haka, ingancin hoto na fitarwa & jin kai yawanci suna gajiyawa idan aka kwatanta da wanda aka samu daga CCDs mai tsaye .

Tatsuniya da kira CCD na CMOS

Faktarai kamar girman pixel, matakin hayaniya, da ingancin canjin hotoelectric dole ne su ya kamata a cikin gaba lokacin da ake kwatanta jin kai na CCD da CMOS . A kwana mai tsaye , a cikin shirin harshe , CCD sensors suna yin aiki mafi kyau daga cikin CMOS sensors na iya yin aiki mafi kyau a cikin aikace-aikace masu sauri ko masu babban resolution.

Kammalawa

Don haka wanne ne ya fi jin kai, CCD ko CMOS? Ba abu ne mai sauƙi ba ne “eh” ko “a’a”. Tsammani akan wannan batu zai yi ma'ana ne kawai idan mun kamata waɗannan abubuwan: takamaiman aikace-aikace da ingancin farashi. Kadai karatuwa an na'urar hoto, shawarar ya kamata ya kamata na so Duk mai haduwa farashi, amfani da wuta, ingancin hoto as da kyau kamar fannin aikace-aikacen kansa.
