Mawu Oyamba

Kukhazikika kwamakamera a digito ndikokhwima, koma osati mu lens ya kamera ya CCTV. Pali njira ziwiri zosiyana zochepetsera kugwedezeka-cam zotsatira.
Kukhazikika kwazithunzi kumagwiritsa ntchito zida zovuta mkati mwa lens kuti chithunzicho chisasunthike komanso kuti chijambule chakuthwa. Zakhalapo kwa nthawi yayitali mumagetsi ogula, koma sizinatengedwe kwambiri mu lens ya CCTV.

Kukhazikika kwazithunzi zamagetsi ndizovuta kwambiri zamapulogalamu, kusankha mwachangu gawo lolondola la chithunzi pa sensa kuti ziwoneke ngati mutuwo ndipo kamera ikuyenda pang'ono.

Tiyeni tiwone momwe onse awiriwa amagwirira ntchito, komanso momwe akugwiritsidwira ntchito mu CCTV.

Optical Image Stabilization

Kukhazikika kwa chithunzi cha Optical, komwe kumatchedwa OIS mwachidule, kumatengera ma lens okhazikika, okhala ndi algorithm ya PID. Lens ya kamera yokhala ndi mawonekedwe owoneka bwino imakhala ndi injini yamkati yomwe imasuntha chinthu chimodzi kapena zingapo zagalasi mkati mwa mandala pamene kamera ikuyenda. Izi zimabweretsa kukhazikika, kutsutsa kusuntha kwa lens ndi kamera (kuchokera kugwedezeka kwa manja a wogwiritsa ntchito kapena momwe mphepo imakhudzira, mwachitsanzo) ndikulola kuti chithunzi chakuthwa, chochepera-chithunzithunzi chijambulidwe.

Kamera yokhala ndi lens yokhala ndi mawonekedwe owoneka bwino imatha kujambula zithunzi zowoneka bwino pamilingo yocheperako kuposa yomwe ilibe.

Choyipa chachikulu ndichakuti kukhazikika kwa chithunzi cha kuwala kumafunikira zowonjezera zowonjezera mu mandala, ndipo OIS-makamera opangidwa ndi magalasi ndi okwera mtengo kwambiri kuposa mapangidwe osavuta.

Pachifukwa ichi, OIS ilibe ntchito yokhwima mu CCTV zoom block makamera.

Electronic Image Stabilization

Electronic Image Stabilization imatchedwa EIS posachedwa. EIS imazindikiridwa makamaka ndi mapulogalamu, alibe chochita ndi mandala. Kuti akhazikitse kanema wosasunthika, kamera imatha kutulutsa magawo omwe sakuwoneka akusuntha pa chimango chilichonse ndi makulitsidwe amagetsi m'dera la mbewu. Zomera za chimango chilichonse cha chithunzicho zimasinthidwa kuti zithandizire kugwedezeka, ndipo mukuwona kanema wosalala.

Pali njira ziwiri zodziwira zigawo zomwe zikuyenda.ina imagwiritsa ntchito g-sensor, ina imagwiritsa ntchito mapulogalamu-kuzindikira zithunzi zokha.

Mukakulitsa kwambiri, m'pamenenso vidiyo yomaliza imatsika.

Mu CCTV kamera, njira ziwirizi si zabwino kwambiri chifukwa cha zinthu zochepa monga chimango mlingo kapena kuthetsa kwa on-chip dongosolo. Chifukwa chake, mukayatsa EIS, imakhala yovomerezeka pakugwedezeka kochepa.
