Pane zvakawanda kune sensor image pane yenhamba yepiksekisi.
Mifananidzo yekhamikari (kana digital camera) ndiyo inoisa "digiti" mune digital camcorder. Ita zvinyoronyoro, chipinhi chechifananidzo chinoshandura chiedza chakabatwa nekccorder yako ye lens uye inoita kuti ive chiratidzo che digital. Icho chiedza chinogadziriswa chinogadziriswa nekuchengetwa mumakccorder's memory yako se digital digital file iyo iwe unogona kuona gare gare pakombiyuta yako kana TV. Pamberi pe lens iro pachako, inzwa yechinhu chinhu chinokosha chinoita kuti vhidhiyo yakanaka ive.
Kune miviri miviri mikuru yekhamcorder image sensors : CCD (inosungirirwa pamwe chete) uye CMOS (complementary metal oxide semiconductor). Zvose zviri zviviri zvechifananidzo cheinjiniya yekambanikiti dzine mazana ezviuru kana kunyange mamiriyoni epikisi. Funga nezvepikisiki sekidiki kadiki inotora chiedza uye ichiita kuti ive chiratidzo chegetsi.
Kuti CMOS & amp; CCD Sensors Kusiyana
MuCCD sensor sensor, pixels inotora chiedza uye inoenda nayo kumucheto we chip apo inoshandurwa kuva chiratidzo che digital. Mune sensor CMOS, chiedza chinoshandiswa pa pixel pachako - hapana bhanhire rekushandisa motokari rinodiwa. Iyi kusiyana yakashata inofunga: nokuti chiratidzo chekuedza hachifaniri kutakurwa kusvika kumucheto wechi chipuko chekutendeuka, sensiti ye CMOS inoda simba shoma kuti rishande. Izvozvo zvinoreva, zvose zvinenge zvakaenzana, kamcorder ine CMOS sensor ichapa upenyu huri nani hwebheteri kupfuura imwe ine CCD. Zvechokwadi, zvinhu zvinenge zvisingaenzani zvakaenzana, saka usangofunga kuti CMOS camcorder ine bhateri huri nani pane imwe CCD imwe.
Kwemakore mazhinji, maCD CCD mafungiro aifungidzirwa kuti ndiyo inyanzvi yepamusoro-soro kusvika kune chifananidzo uye yehudhi yepamusoro yaifungidzirwa. Zvisinei, masero e CMOS akaita nhanho dzakawanda mumutoro iwoyo uye zvino anowanikwa panhamba inowedzera yemakcorders pamatengo ose. Semu, somuenzaniso, ikozvino anoshandisa sensiti ye CMOS iri kumusoro-ye-in-line high definition camcorder, HDR-XR520V.
Saka, apo CMOS neCCD sensor sensor zvinosiyana, hazviiti nenzira inofanirwa kuve yakakosha kune mutengo wevashambadziri. Iwe unofanirwa kubhadhara zvishomanana kune rudzi rwe sensor mu camcorder yako uye kunyanya kufunga kune pixel count uye ukuru hwemuviri we sensor.
Pixel Counts
Paunongorangarira majekiti emakcorder, iwe uchawanzoona maviri einhamba dzezviverengero dzakanyorwa ne sensor: pikelel yakawanda nhamba uye nhamba yakakosha yepikeleri. Iko yakawandisa kuverenga inoreva nhamba yepiksesi yose pane sensor, asi inoshanda inokuudza kuti vangani mapikiseti achashandiswa paanotora vhidhiyo kana zvichiri mifananidzo. Saka, nyatsoteerera kudivi yepikisi yakawanda apo uchitsvaga kugadzirisa kwevhidhiyo yako.
Iko inobatsira pixel count inokosha kune chimwe chikonzero: inokubatsira kuti ucheke kuburikidza nekudhinda mamwe hype. Tora Camcorder A. Inoti inogona kutora 10-megapixel photo (kureva mufananidzo ane mamirikisi gumi emamiriyoni mairi). Asi paunotarisa nhamba yemapiksesi anoshanda pamusana wechiratidzo chemufananidzo, unoona inongova 4-megapixel sensor. Iko-ine-megapixel yechiso chemufananidzo inotora sei 10-megapixel chithunzi? Yakaitwa kuburikidza nekugadzirwa kunonzi interpolation. Sezvo mutemo wehurumende, iwe unofanirwa kubvisa kunaka kwezvifananidzo zvakagadzirwa kuburikidza nekushandura. Pane kudaro, shandisa nhamba yemapiksesi anoshanda pamutsara wekhamera semutungamiri wekugadzirisa kwechokwadi kwemafoto ako.
Kukosha Kwemufananidzo Sensor Size
Nhamba yepikisiki pane sensor sensor haisi iyo chete inokonzera kunaka kwevhidhiyo yakatorwa. Ukuru hwemuviri we sensor nenyaya. Mifananidzo yakakura yezvifananidzo inokwanisa kutora chiedza chakawanda kudarika zviduku, kunyange kana dzine pixels shomanana. Ndiko nokuti, kunyange zvishomanana muhuwandu, aya mapikisikasi makuru uye naizvozvo anokwanisa kutora chiedza chakawanda.
Ichi ndicho chikonzero iwe uchaona camcorders kushambadzira kwete chete nhamba yemapikisikisi pane chinyorwa chemufananidzo, asi hukuru hwe sensor pachayo (kazhinji muzvikamu zvemasendimita). Iwe uri nani pane kutenga kaccorder nekakura hurukuro yezvifananidzo kunyange kana ine pikisiki shomanana kupfuura muenzaniso wekukwikwidzana neine sensor maduku uye mamwe mapikiseti.
