Kamera masanjidwewo

ogula Russian ayamba wotchuka digito makamera ndi makamera. Tsiku lililonse, opanga dziko kubala zitsanzo latsopano, kupereka mwayi kwambiri pa zithunzi. Masiku ano, anthu ambiri kungakhale kovuta kudziwa kusankha kamera. Nthawi zina anakumana antchito mu sitolo ndipo sangathe kupereka bungwe bwino bwino. N'chifukwa chake wokonda kujambula, ndipo makamaka katswiri ayenera kudziwa zina mwa zinthu ndi makhalidwe zipangizo zamakono.

The masanjidwewo kamera ndi mbali yofunika zipangizo zimenezi. Ndi kachipangizo chipangizo ndi tilinazo wa Kumwambamwamba, amene samalani kutembenuka kwa fano kuwala ntchito n'kufika pa disolo, kuti mbendera yadigito. kamera kapena masanjidwewo kamera kumakhudza mwachindunji kubowola ndi khalidwe la mafano. Tiyeni tione pa izo mfundo imeneyi.

digito kamera masanjidwewo chikuphatikizapo kuchuluka kwa zinthu kuwala tcheru, amene atembenuke fano kuwala mu magetsi. Aliyense mapikiselo aumbike mwa mmodzi dontho masanjidwewo fano komaliza. Ndi kapangidwe awo akhoza kugawidwa mu zonse chimango, mwapang'onopang'ono jambulani, ndi mzati buffered ndi chimango buffering maganizo zinayambira ndi interlaced. Pankhaniyi, masanjidwewo akhoza kugawidwa mu mitundu iwiri waukulu omwe tsopano ambiri amene makamera anagulitsa.

Mitundu makamera mawerengetsedwe

Kwa nthawi yaitali ife takhala ntchito ngati zidindo wowonjezera semiconductors zitsulo okusayidi (CMOS) amene tilinazo kuwala anapeza mu zaka zao za sikisite lapansi. Apa, mbendera readout zikhoza kutheka kulikonse, inu muyenera mwachindunji mzere ndi yachiwiri. Choncho aliyense mapikiselo ali Werengani chizindikiro mkuzamawu. Patapita panali zida kuti ankayang'anira-zolumukizidwa chipangizo (CCD), zomwe pachiyambi anali kwambiri kuposa CMOS-masanjidwewo. M'magulu otere, mbendera kuwerenga anachita chimodzimodzi CRT (cathode ray chubu), i.e. kuchokera kumanzere kupita kumanja ndipo pamwamba mpaka pansi. Pakachitsulo photodiodes anali mu nkhani iyi monga zinthu photosensitive. Mu nineties oyambirira zinabala kuwongolera kwambiri CMOS-kachipangizo. Chifukwa cha ziwalo za mtundu wa mawerengetsedwe ngati nkotheka kupeza tilinazo zabwinobwino komanso apamwamba chifaniziro chabe pa mawerengetsedwe ndithu lonse chotchuka ntchito makamera katswiri miyeso lalikulu. Ngati ife kulankhula za zitsanzo zofufuzafufuza angakwanitse, ndi bwino kusankha kuti zili ndi bokosi CCD. Companies monga Canon ndi Nikon makamera kubala zitsanzo ndi kusinthidwa CMOS-masanjidwewo, ndi mtundu wa dongosolo kusintha.

Masanjidwewo kamera ali khalidwe ofunika kwambiri monga m'chigamulocho. Mu kusamvana amatanthauza chiwerengero cha zinthu tcheru ku masanjidwewo, aliyense amene amalandira kuwala ndi otembenuka mu yeniyeni mlandu magetsi. Nkofunika kudziwa kuti safuna m'lingaliro kuthamangitsa chiwerengero cha pixels monga khalidwe la zithunzi kusindikizidwa pafupifupi zofanana, ndipo kusiyana zitha kuwoneka pansi pa galasi lokulitsira.

khalidwe lina lofunika amene ali bokosi kamera ndi kukula thupi. zambiri kuposa lalikulu thupi kukula ali bwino mbendera / phokoso chiŵerengero, kuti athe kupeza chifano cha apamwamba khalidwe, ndi mtundu achilengedwe. Amene anganene kuti wamkulu kukula kwa masanjidwewo pa angapo pixels, ndi apamwamba khalidwe mafano.
