I-Optical Image Stabilization (OIS) ubuchwepheshe obuguqule umhlaba wokuthwebula izithombe kanye nokubhekwa kwe-CCTV.

Kusukela ngo-2021, ukusimama kwesithombe kuye kwavela kancane kancane ekuqaphelweni kwezokuphepha, futhi kunomkhuba wokushintsha ilensi evamile yokusimamisa isithombe. Ngoba ivumela ukuthwebula izithombe ezicijile nezicacile ngisho nasezimeni ezinyakazayo, okuyenza ibe isici esibalulekile kumakhamera esimanjemanje. kanye namakhamera e-CCTV. Kodwa isebenza kanjani i-OIS? Kulesi sihloko, sizohlola ubuchwepheshe obusemuva kwe-OIS ngesistimu-esekelwe ilensi.

I-OIS iyisistimu enxephezela ukunyakaziswa kwekhamera ngokuhambisa izakhi zelensi ziye kolunye uhlangothi lokunyakaza. Isebenza ngokusebenzisa i-gyroscope kanye ne-accelerometer ukuthola ukunyakaza kwekhamera. Ulwazi olusuka kulezi zinzwa lube seluthunyelwa kusilawuli esincane, esibala inani nesiqondiso sokunyakaza kwamalensi okudingekayo ukuze kumelane nokunyakaziswa kwekhamera.

Isistimu esekelwe ilensi-ye-OIS isebenzisa iqoqo lezinto ezikulensi ezinganyakaza ngokuzimela ngaphandle kwendikimba yekhamera.

Izakhi ze-lens zifakwe kumamotho amancane angashintsha indawo yawo ekuphenduleni ukunyakaza okutholwe yizinzwa. Amamotho alawulwa yi-microcontroller, elungisa indawo yawo ukuze amelane nokuzamazama kwekhamera.

Kukhamera, i-OIS ivamise ukusetshenziswa kwilensi ngokwayo, njengoba kuyindlela ephumelela kakhulu yokunxephezela ukuzamazama kwekhamera. Nokho, kukhamera ye-CCTV, i-OIS ingasetshenziswa emzimbeni wekhamera noma kumalensi, kuye ngokuthi iklanywe futhi isetshenziswa kanjani.

I-lens-based system ye-OIS inezinzuzo ezimbalwa kunezinye izinhlobo zezinhlelo zokuzinzisa. Isebenza kahle kakhulu ekunxephezeleni ukuzamazama kwekhamera, njengoba ingalungisa kukho kokubili ukunyakaza okujikelezayo nokuhumusha. Iphinde ivumele ukulungiswa okusheshayo nokunembe kakhudlwana, njengoba izakhi zelensi zingahamba ngokushesha nangokunembile ekuphenduleni ukunyakaza okutholwe izinzwa.

Sengiphetha, i-OIS iwubuchwepheshe obulithuthukise kakhulu izinga lezithombe ezithathwe amakhamera namakhamera e-CCTV. I-lens-based system ye-OIS iyindlela ephumelelayo nephumelelayo yokunxephezela ukuzamazama kwekhamera, okuvumela izithombe ezibukhali nezicacile ngisho nasezimeni ezinyakazayo. Ngokukhula kwesidingo sokuthatha izithombe zekhwalithi ephezulu emikhakheni eyahlukene, i-OIS kulindeleke ukuthi ibaluleke nakakhulu esikhathini esizayo.
