Mufananidzo wacho ndicho chinhu chedu chikuru uye chakakosha chebasa, asi Wati wakambozvibvunza here kuti mufananidzo chii uye unosvika sei kuuropi? Muchinyorwa chino ndinoda kugovana newe pfupiso yemaitiro atinogamuchira mifananidzo uye fananidzo iriko pakati pehurongwa hwehupenyu (huropi neziso revanhu) nedigital system (asi zvakare analogog) mumifananidzo nemavhidhiyo kamera.
Pfungwa yatinayo yepasirese, maonero edu echokwadi, ezvakatikomberedza uye nezvedu pachedu, imhaka yechikamu chikuru kupindira kwemaanalogical process (kana mechina maitiro), kunyangwe paine zvisaririra. Physiologists uye vadzidzi vechiitiko ichi vakachengetedza munhoroondo yese kuti chiratidzo chevanhu chine akawanda mapoinzi akaenzana nedhijitari maitiro nekuda kwekuti pikicha kana vhidhiyo makamera uye ma scanner anotora mifananidzo. Uye, hazvingagone kuve zvimwe, muviri wemunhu ndiwo muchina wakakwana uye une simba pasi rose, hungave hupenzi kusautora sechirevo kana uchitanga kugadzirwa kwemaitiro ekutora uye kuburitsa mifananidzo. Neimwe nzira, chiratidzo chevanhu chiitiko che "digital", uye ndinotaura izvi mumakotesheni nekuti zviri pachena kuti pane misiyano yakawandisa pakati pezvienzanidzo zviviri, asi nehasha izvo zvikamu zvechiitiko zvine basa rakafanana rakafanana.
Funga nezve chishandiso chakaumbwa neyakaomarara autofocus system iyo inogadzira mwenje inoratidzirwa kubva kuzvinhu kusvika kumadziro ekumashure ebhokisi. Rusvingo urwu rwakatenderedzwa nema sensors madiki, imwe neimwe inobata chikamu chidiki chemufananidzo. Zvakare fungidzira kuti ma sensors aya anotumira iyo data yakabva yawanikwa kune processor inokwanisa kuodha chimwe nechimwe cheruzivo kubva kune yega sensor kuti vagadzire mufananidzo. Irremediably mufananidzo uye pfungwa inouya mupfungwa ndeyeyeye kamera kamera Ndizvozvo?
Uye ndeyekuti sensor yekamera inoumbwa nemaseru madiki, imwe neimwe inowana ruzivo nezve chikamu chidiki chemufananidzo. Isu tiri kutaura nezve fundus, iyo inogovera chimiro chakafanana neicho chatichangotsanangudza nemadhijitari kamera. Mumaziso medu mune nhevedzano yeema sensors anonzi photoreceptors, akaumbwa sekoni uye tsvimbo, ayo, kuburikidza nemaphotoochemical process, anoputsa mufananidzo wavanogamuchira kuita zvidimbu zvidiki zve data. Ruzivo urwu rwunopfuudzwa kuburikidza nemaziso etsinga, ayo anopedzisira ari muuropi, iro basa rayo nderekudzosera data rese kuti riumbe mifananidzo yakazara. Makoni ane basa rekuona kwemavara uye epakati chiratidzo; Vanoda mwenje wakanaka kuti vashande. Iwo machira anotarisira ekuonekwa uye anogona kushanda mune mashoma mwenje.
Mufananidzo uyu inzira yekuona chokwadi chakakonzerwa nekutapurirana kwechiedza. Kana tawana chifananidzo, hatisi kuwana chiratidzo chemaviri-emhando yezvinhu, iyo inogadzirwa kana mwenje uchipfuura neparenzi uye uchifungidzirwa pamusoro. Maitiro ekuona ari nyore kwazvo, chinhu chakakosha chinoita kuti maitiro ese agone kuve nyore. Chiedza chinoburitsa zvinhu uye chakanangiswa kune ziso, icho chisiri chinhu kunze kwekunyanyisa kuomesa chinangwa chemifananidzo, pazasi payo pane emulsion yehupenyu. Zvinhu zvakasiyana zvine masimba akasiyana ekuratidzira mwenje, uye zvinoenderana newavelengths ayo anoratidza, (rangarira, semuenzaniso, kuti izvo zvinoitwa neruvara dema zvinotora mwenje nepo iro jena jena riri kuratidza kuti rinoburitsa huwandu hwakawanda) riine rumwe ruvara kana rumwe uye nehukuru hwakasiyana. Uye uchitora zvese izvi uchifunga, kana uchitora mifananidzo murume akagadzira zvishandiso zvinotevedzera maitiro eziso remunhu. Analog Photographic uye cinematographic makamera inzira nehurongwa hwemalensi ayo anojekesa mwenje kune emulsion yesirivheri. Dhijitari ichiripo uye mavhidhiyo makamera anoita zvimwechetezvo, asi ivo vanoratidzira iwo mufananidzo kune iyo chifananidzo chinotora chip inonzi CCD (Inobhadharwa Yakabatanidzwa Chishandiso). Aya ndiwo maseketi akabatanidzwa ayo anoshandisa mukana wekugona kweimwe semiconductor zvinhu kuburitsa chiratidzo chemagetsi pavanogamuchira mafotoni. MaCCD, ayo anoumbwa nezviuru zvemasero madiki-ekuunganidza mwenje, anotyora mufananidzo pasi kuzviuru zvezvimedu zvidiki. Iwo akaumbwa nemaseru madiki, rimwe nerimwe rinorekodha nekufambisa ruzivo rwunoenderana nechimwe chidimbu chemufananidzo, sekunge chirahwe.
Zvinoshamisa izvo? Pano iwe une mufananidzo unopfupisa izvi zvakafanana chaizvo uye izvo zvinoita kuti tinzwisise zvakajeka kuti makamera anoshanda sei.
