Saizi yekufungidzira zvakare saizi yechidzitiro;
Saizi yemufananidzo we sensor:
Ramba uchishandisa chiyero chefomati saizi yechubhu yekamera, ndiyo saizi yekunze yedhayamita yechubhu yekamera.
2.Focal urefu
Pfungwa iyi inoreva chinhambwe kubva pakati pelenzi kusvika padanho rekuunganidza chiedza.Iyo zvakare chinhambwe kubva pakati pe lens kuenda kundege yekufungidzira ye sensor surface mu module.Kureba kwakakosha kwakakosha. data, uye ichashandiswa mukuverenga kudzika kwemunda uye FOV mune ramangwana.
3.Maonero
Kune marudzi matatu emalenzi: akajairwa, akafara-ekona, uye telephoto lens.
Kunyange zvazvo nzvimbo iyo ziso remunhu inogona kuona inogona kusvika madhigirii 180, kona inogona kunyatsoona chimiro uye ruvara inenge madhigirii 50. Kazhinji, kona yekuona yebato rekubata i55 degrees kusvika ku65 degrees.Ehe, zvinofanirwa kunge zvichibva pane izvo chaizvo zvinodiwa nevatengi;Seesaw musimboti,Vagadziri veLens vanotarisira kugadzira nzvimbo yakakura yekuona iyo inogona kukodzera masensor mazhinji, asi yakakura iyo ndima yekuona, yakakura iyo chromatic aberration inoda. kukurirwa.
4.Chromatic aberration
Iyo lenzi yemifananidzo haigone kudzoreredza zvachose poindi kana musanganiswa-wavelength mwenje mufananidzo kune imwe nzvimbo, asi ine fuzzy diffuse nzvimbo;mufananidzo wechinhu yendege hausisiri ndege, asi nzvimbo yakakombama, uye mufananidzo warasa kufanana.Izvi zvinokanganisa zvekufungidzira zvinonzi chromatic aberrations.
5.Depth of Field & Depth of Focus
(1) Kudzika kweMunda & Kudzika kweKutarisa
Pamberi uye mushure mekutarisa, mwenje unotanga kuungana uye kupararira, uye mufananidzo wepoindi unova wakasviba, uchigadzira denderedzwa rakakura.Denderedzwa iri rinonzi denderedzwa renyonganiso.
Muchokwadi, mufananidzo wakatorwa unoonekwa neimwe nzira (senge fungidziro, magnification kuita mufananidzo, nezvimwewo).Mufananidzo wakanzwikwa neziso rakashama une hukama hukuru nekukura, kureba kwekufungidzira uye kureba kwekuona.Kana dhayamita yedenderedzwa rekuvhiringidzika iri diki pane kugona kusarura kweziso remunhu, blur inogadzirwa nemufananidzo chaiwo muhuwandu hwehukama haigone kuzivikanwa.Iri denderedzwa risingazivikanwe renyonganiso rinonzi denderedzwa rinotenderwa rekuvhiringika.
(2) kudzika kwemunda
Pane denderedzwa rinotenderwa rekuvhiringika pamberi uye shure kwenzvimbo, uye chinhambwe chiri pakati pemadenderedzwa maviri ekuvhiringika chinodaidzwa kuti hudzamu hwekutarisa.Pamberi uye shure kwechidzidzo (focus point), chifananidzo chichiri nehupamhi hwakajeka, hunova hudzamu hwemunda.Mune mamwe mazwi, kudzika kwemberi neshure kwechidzidzo uye chiyero chekusvibiswa kwemufananidzo pamusoro pefirimu zvose zviri mukati memuganhu wedenderedzwa rinobvumirwa rekuvhiringidzika.
Kudzika kwemunda kunosiyana nehurefu hwakatarisana nelens, kukosha kwekuvhura, uye kureba kwekupfura.Pakureba kwakatarwa uye chinhambwe chekupfura, diki buri rinoshandiswa, ndiko kuwedzera kudzika kwemunda.Nheyo yemyopic rudo squinting.

Kutadza kunyatsotarisisa
Paunenge uchigadzira Iyo Holder, iyo yekumashure inotarisisa sitiroko yelenzi kubva kure kusvika pedyo ichave mukati meiyo VCM.Kana hurefu hweChibatiso husina kugadzirwa zvakanaka, chibatiso chiri palenzi chiri padhuze netarisiro chichaonekwa, zvichikonzera kushata pedyo nekutarisisa.
6.Kukanganisa
Izvi zvinonzi distortion zvinoreva mwero wekuti mutsara wakatwasuka unoshanduka kuita curve mushure mekupfura nemu lenzi.Chiyero chekukanganiswa chinoverengerwa sechikamu cheshanduko yehukuru hwekufungidzira kusvika pakukura kwekufungidzira kwakakodzera.Kugadziriswa kweziso remunhu kune kona i1 miniti yeradian, inova 1/60 ye1 degree, uye inonyatso. inonzwisisa kutwasanuka uye kukombama kwemutsara.Naizvozvo, akawanda optical imaging lenzi ane hanya zvakanyanya nekutsauka kwemunda angle yekukudza, kazhinji inoiswa pa2%.
7.Relative illuminance
Chirevo, chiyero chekuvhenekera chemunda wekuona pamwe neakisi ye optical kusvika kumunda uzere wekuona pane ndege yekufungidzira, ndiko kuti, chiyero cheiyo diagonal makona eiyo sensor yemufananidzo kune kupenya kwepakati, kukosha uku kunorambidzwa necos4θ. theorem of illuminance, uye makona iunit area Iyo inopenya inoyerera yeinopenya inoyerera yakaderera, asi isina kuderera zvekuti kune chiitiko che vignetting.
