Mmene Image Stabilizer

Kamera kugwedezeka ndi chimodzi mwa zinthu kwambiri zokhudza khalidwe la kanema wa. Pasanakhale fano stabilizer, kujambula zinali zotheka ntchito miyendo itatu ndi. Mwa njira iyi kotheka kutsimikizira zotsatira zabwino. Komabe, nthawi zambiri ntchito miyendo itatu ndi zimaphwanya ife sayenda ndi dzuwa. Canon zachitika wapadera mu mtundu dongosolo la olimba kuwala, amene amalola kuti circumvent malire izi.

Tikumbukenso kuti m'dongosolo amatigwiritsa ntchito gyroscopes, koma iwo ali kakang'ono ndithu, ndi ntchito yokhayo ngati kachipangizo kwa potseka kayendedwe ka mandala, palibe ena chachikulu swirling zachitsulo zikondamoyo, pamodzi ndi ntchito batire yaikulu ndi magetsi galimoto chifukwa torsion awo. Iwo ankakhulupirira kuti zipangizo amenewa amafuna yambiri mphamvu, koma limeneli linachokera sizoona. Kumene, ngati ntchito kwa maola, zidzakhala kwambiri mowa mphamvu.

Image Stabilizer: opareshoni

Tiyeni tione mfundo zofunika kwambiri zokhudza ntchito chipangizo. Chithunzi stabilizer akugwiritsa cholinga mandala mu ndege likufanana ndi filimu. Ngati disolo anawamvera chifukwa ozunguza ndi matabwa kuwala ndi unachoka malo awo ndi kulemekeza olamulira kuwala, ndi kuti ali wobwezera chifukwa cha zithunzi amaona. Ngati kosangalatsa mandala olimba ndege amene ali perpendicular kwa ndege ya filimuyi, moyenera kukwaniritsa kayendedwe mandala, n'zotheka kuti tikwaniritse zotsatira, pamene kunyezimira kuwafika filimu ndege, kukhala pafupifupi ima. Mu likulu la fano ukusunthira pansi pa filimu. Ngati kusamutsidwa amapezeka olimba mandala gulu motsogozedwa ofukula, ndi matabwa a amene anafuna kuti fano n'kupanga, refracted, ndiye kuchimake chithunzi malo a chimango lapansi. Chotero kayendedwe parasitic kutenga malo mbali zonse ziwiri, moti disolo akhoza ankatembenukira malangizo onse perpendicular kwa mandala olamulira ndi kufanana kwa ndege filimu.

Image stabilizer - si kayendedwe ka disolo. Kagulu kalikonse za kamera analanda masensa awiri chofunika gyroscopic mtundu. Iwo amaonetsera mbali ndi liwiro la kugwedezeka kamera kuti ndi zinthu achilendo pamene kuwombera imagwiridwa ndi manja. Masensa zili mu gulu lapadera, amene amalola kuti muwasunge iwo kuletsa zolakwa kugwirizana ndi shutter actuation kapena kusamutsidwa anachita kalirole.

Olimba mandala wagawo ndi galimoto mwachindunji kuchokera pakati. Chotero yaing'ono, opepuka chipangizo kuti amadya zochepa mphamvu, Poyankha nthawi yake ndi waufupi kwambiri. The kuwala chithunzi stabilizer angathe efficiently kwambiri azilipira kwa kugwedera pafupipafupi 0.5-20 Hz.

Mukhoza mwatsatane kudzera utoto ntchito chipangizo:

- by chosakwanira kukanikiza shutter kumasulidwa batani ndi adamulowetsa olimba mandala gulu ndi masensa gyroscopic kuti adziwe kusamutsidwa chipinda;

- anatsimikiza mtima masensa ngodya ndi liwiro kugwedera, ndipo mfundo yopezeka kwa microcomputer ya;

- nkhaniyi kukonzedwa ndi microcomputer pa kayendetsedwe chipangizo lamulo olimba, kenako kutengerapo awo;

- akugwiritsa fano stabilizer mandala gulu perpendicularly kwa olamulira ndi;

- pa izi mudziwe kosangalatsa zoyesera ndondomeko, kenako zimafalitsa kuti microcomputer ya;

- Ndi chizindikiro microcomputer ulamuliro akuyerekezedwa ndi chizindikiro kwa chipangizo kudziwika, maganizo ulamuliro osuschestlyaya analandira. Popeza chodziwa digiri olondola mu gulu olimba mandala.
