The Long Range Optical Defog Zoom Camera Module

Pali mitundu iwiri yaukadaulo wa defoggawo lalitali lokulitsa kamera.
Optical defog
Nthawi zambiri, kuwala kowoneka bwino kwa 770 ~ 390nm sikungadutse munkhungu, komabe, infrared imatha kudutsa munkhungu, chifukwa infrared imakhala ndi utali wotalikirapo kuposa kuwala kowoneka bwino, komwe kumakhala ndi zotsatira zowoneka bwino.Mfundoyi imagwiritsidwa ntchito mu optical defog, ndikutengera mandala apadera ndi fyuluta, kotero kuti sensa imatha kuzindikira pafupi ndi infrared (780 ~ 1000nm), ndikuwongolera chithunzicho kumveka bwino kuchokera kugwero ndi optically.
Koma chifukwa infrared ndi kuwala kosawoneka, sikungatheke pa chipangizo chopangira zithunzi, kotero chithunzi chakuda ndi choyera chokha chingapezeke.

E-defog
Electronic defog ndikugwiritsa ntchito ma aligorivimu osintha zithunzi kuti akweze chithunzicho.Pali machitidwe angapo a electronic-defog.
Mwachitsanzo, ma aligorivimu omwe siachitsanzo amagwiritsidwa ntchito kuti awonjezere kusiyanitsa kwazithunzi, potero kuwongolera mawonekedwe owoneka bwino.Kuphatikiza apo, pali njira yobwezeretsanso chithunzi chotengera chitsanzo, yomwe imasanthula zomwe zimayambitsa chifaniziro chowunikira ndi kuwonongeka kwa zithunzi, kutengera njira yochepetsera, ndikugwiritsa ntchito kukonzanso kosiyana kuti pamapeto pake zibwezeretse chithunzicho.Mphamvu yamagetsi-defog ndi yofunika kwambiri, chifukwa nthawi zambiri chifukwa cha mdima wandiweyani wa chithunzicho chikugwirizana ndi kuthetsa kwa lens palokha ndi algorithm yokonza zithunzi kuwonjezera pa chifunga.
Kukula kwaukadaulo wa defog
Kumayambiriro kwa chaka cha 2012, gawo la kamera ya block zoom SC120 yomwe idakhazikitsidwa ndi Hitachi ili ndi ntchito ya defog.Posakhalitsa, Sony, Dahua, Hivision, etc. adayambitsanso zinthu zofanana ndi electronic-defog.Pambuyo pazaka zingapo zachitukuko, ukadaulo wamagetsi-defog wakula pang'onopang'ono.M'zaka zaposachedwa, opanga magalasi amalumikizana mozama ndi opanga makamera, ndipo motsatizana akhazikitsa mitundu yosiyanasiyana ya makamera.Optical defog zoom kamera block kamera module .
Yankho ndi View Sheen
View Sheen yakhazikitsa mndandanda wamakulitsidwe kamera moduleokonzeka ndi super defog (optical defog + electronic defog).Njira yamagetsi + yamagetsi imagwiritsidwa ntchito kukhathamiritsa kuchokera ku gwero la kuwala mpaka kumapeto kwa ISP processing.Gwero la kuwala liyenera kulola kuti kuwala kwa infrared kupitirire, kotero kuti lens lalikulu, sensor yaikulu ndi fyuluta yokhala ndi zotsatira zabwino zotsutsana ndi reflection ziyenera kuganiziridwa mozama.Ma aligorivimu ayenera kutengera zinthu monga mtunda wa chinthu ndi kukula kwa chifunga, ndikusankha mulingo wa defog, kuchepetsa phokoso lomwe limayambitsidwa ndi kukonza zithunzi.
