Paunotenga Kiraera, Zvakakosha Kuziva Kusiyana
Kamcorders dzakawanda (uye kunyange mafoni emafoni) dzinosanganisira mamwe maitiro ekusimudzirwa kwechifananidzo (IS) teknolojia yekugadzirisa kuderera kwevhidhiyo iyo inoguma nemaoko asina simba kana kufamba kwemuviri. Icho chinonyanya kukosha ndechetatu asi pane maitiro maviri emichina inotora iyo danho rinopfuurira: optical uye digital.
Chimiro chekusimudzira chakakosha kune vose camcorders, asi inonyanya kukosha mune izvo zvishoma nezvishoma zvinovharidzirwa kana kuti marefu optical zoom lenses. Apo lenzi inoswededzwa kusvika pakukwirira kwayo kukuru, inova yakanyanyisa kunetseka kunyange kunyange kumhanya kuduku.
Vamwe vanogadzirisa vanoisa zita rechigadzirwa pamagetsi ekugadzirisa mufananidzo wavo. Sony inorika SteadyShot apo Panasonic inodana yavo Mega OIS uye Pentax Shake Reduction . Mumwe nomumwe ane zvinyorwa zvake asi vanoita basa rimwe chete.
Chero mamiriro ezvinhu, iwe unofanirwa kutarisa nguva dzose mushure mokutengeserana nyaya uye kutarisa zvinotaurwa. Inofanira kuratidza kana akapiwa camcorder ine optical kana digital stabilization kana maviri.
Optical Image Stabilization
Optical image stabilization (OIS) ndiyo inonyanya kushandiswa yemufananidzo kugadzikana. Makamera ane optical image stabilization anowanzoita zviduku zvinonzi gyro-sensors mukati memwenje inokurumidza kuchinja zvidimbu zveglasi remaziri kuenda kune-off-set motion musati mifananidzo ishandurwa kuva fomu yemadhigiri.
Chigadzirwa chemasikirwo inogadziriswa inofungidzirwa yakanyatsooneka kana ikaratidza chinhu chinofamba mukati memwenje.
Mamwe makcorder makhizha anokubvumira kuti utsigise mufananidzo wakagadzikana uye wovhara, kana kusanganisira mamiriyoni emagetsi ekubhadhara marudzi akasiyana-siyana ekamera-shanduko (kana yakananga kana yakanamatira).
Digital Image Yakagadzikana
Kusiyana nemashandisirwo emagetsi, digital image stabilization (inonziwo yekugadzirwa kwemagetsi yemufananidzo, kana EIS) inoshandisa teknolojia yehusaiti kuderedza kusvibiswa kwemaoko asina kufanira pavhidhiyo. Zvichienderana nemuenzaniso, izvi zvinogona kuitwa nenzira dzinoverengeka.
Mamwe makcorders achaverenga kuchinja kwemuviri wako kushanduka uye kushandisa iyo data kuti ichinje kuti mapikisi emaikirini emakccorder anogadziriswa ari kushandiswa. Inoshandisa pixels kubva kune imwe nzvimbo inooneka sechinyamupinyi chekufambisa kunotarisa pamusoro pechirongwa chekushandura nechirongwa.
Kune vatengi vemakambani emakambani, chimiro chekugadzirisa chidimbu chinowanzosanyanya kushanda kupfuura optical stabilization. Zvichipa izvozvo, inobhadhara kutarisisa zvakanyanya apo kamcorder inonzi ine "chimiro chekusimudzira." Icho chinogona kungova chechidijiti zvakasiyana-siyana.
Panewo mapurogiramu epurogiramu anokwanisa kushandiswa kugadzirisa firiji kune vhidhiyo kunyange mushure mokunge yatorwa, nekutevera kufamba kwepikisi uye kugadzirisa fomu. Zvisinei, izvi zvinoguma kana mufananidzo wakaderedzwa kubva pamusana wakaderera kana kuti extrapolation kuti uzadze mhete dzakarasika.
Mamwe Mifananidzo yeMagetsi Okugadzirisa
Kunyange zvazvo optical uye digital stabilization yakawanda, dzimwe mhando dzinoedza kugadzirisa vhidhiyo isina kugadzikana zvakare.
Semuenzaniso, kune dzimwe nzira dzekunze dzinosimudzira muviri wose wekhamera panzvimbo yekuita kuti zviitike mukati memera lensera. Nzira iyo inoshanda nayo ndeyokuita gyroscope yakabatanidzwa mumuviri wekhamera kuti iite kugadzikana. Izvi zvinowanzoonekwa painofananidza kubva mumotokari inofamba.
Imwe inonzi orthogonal transfer CCD (OTCCD), iyo inoshandiswa mukuongorora nyeredzi kuti igadzikane nemifananidzo.
