Kapangidwe ka chithunzi chopangidwa ndi lenzi yosiyana

Nkhani yokhudza Katundu wa chithunzi chopangidwa ndi lenzi yosiyana

Mtunda wa chinthucho ndi wocheperako kuposa kutalika kwa focal kwa lens yokhotakhota (do > f)

Kutengera kuwerengera kwa kapangidwe ka chithunzi pogwiritsa ntchito lenzi yopingasa, zitha kutsimikizika kuti ngati mtunda wa chinthu (do) ndi wocheperako kuposa kutalika kwa focal (f), ndiye kuti mawonekedwe a chithunzi ndi awa:

– Pakompyuta zikutanthauza kuti kuwala sikudutsa pachithunzichi

- Wowongoka

- Chinthucho chikakhala kutali ndi lenzi yopingasa, kukula kwa chithunzi kumakhala kochepa.

– Chinthucho chikakhala kutali ndi lenzi yopingasa, chithunzicho chikakhala kutali ndi lenzi yopingasa.

Mtunda wa chinthucho ndi waukulu kuposa kutalika kwa lenzi yokhotakhota (do > f)

Kutengera kuwerengera kwa kapangidwe ka chithunzi pogwiritsa ntchito lenzi yopingasa, tinganene kuti ngati mtunda wa chinthu (do) ndi waukulu kuposa kutalika kwa focal (f) ndiye kuti mawonekedwe a chithunzi ndi awa:

– Pakompyuta zikutanthauza kuti kuwala sikudutsa pachithunzichi

- Wowongoka

- Chinthucho chikakhala kutali ndi lenzi yopingasa, kukula kwa chithunzi kumakhala kochepa.

– Chinthucho chikakhala kutali ndi lenzi yopingasa, chithunzicho chikakhala kutali ndi lenzi yopingasa.

Mtunda wa chinthucho ndi wofanana ndi kutalika kwa lenzi yokhotakhota (do = f)

Kutengera kuwerengera kwa kapangidwe ka chithunzi cha lens yopingasa, tinganene kuti ngati mtunda wa chinthu (do) uli wofanana ndi kutalika kwa focal (f) kwa lens yopingasa ndiye kuti mawonekedwe a chithunzi ndi awa:

– Pakompyuta zikutanthauza kuti kuwala sikudutsa pachithunzichi

- Wowongoka

- Yachepetsedwa (kukula kwa chithunzi ndi theka la kukula kwa chinthucho)

– Mtunda wa chithunzi ndi wocheperako kuposa mtunda wa chinthu (mtunda wa chithunzi ndi wocheperako nthawi ½ kuposa mtunda wa chinthucho)

1. funso: Ndi chithunzi cha mtundu wanji chomwe chimapangidwa ndi lenzi yosiyana? yankho: Lenzi yosinthasintha nthawi zonse imapanga chithunzi chowoneka bwino, cholunjika, komanso chochepetsedwa.
2. funsoKodi malo a chinthucho amakhudza bwanji kukula kwa chithunzi chopangidwa ndi lenzi yosiyana? yankho: Mosasamala kanthu za malo a chinthucho, lenzi yosinthasintha nthawi zonse imapanga chithunzi chochepetsedwa.
3. funsoKodi chithunzi chopangidwa ndi lenzi yosiyana chili kuti poyerekeza ndi lenziyo? yankhoChithunzi chopangidwa ndi lenzi yosiyana chili mbali yomweyo ndi chinthucho, mkati mwa kutalika kwa lenzi.
4. funsoKodi kutalika kwa lenzi yosiyana kumakhudza bwanji malo ndi kukula kwa chithunzicho? yankho: Kutalika kwa lenzi yozungulira sikusintha mfundo yakuti chithunzicho chili cholondola, cholunjika, komanso chocheperako, koma lenzi yokhala ndi kutalika kwafupikitsa kwa lenzi imapanga chithunzi chaching'ono pafupi ndi lenziyo, poyerekeza ndi lenzi yokhala ndi kutalika kwakutali.
5. funsoKodi lenzi yosiyana ingathe kupanga chithunzi chenicheni? yankho: Ayi, lenzi yosiyana singapange chithunzi chenicheni. Nthawi zonse imapanga chithunzi chenicheni.
6. funsoKodi kusintha mtunda wa chinthu kumakhudza bwanji malo a chithunzi chopangidwa ndi lenzi yosiyana? yankho: Pamene chinthucho chikusuntha kutali ndi lenzi, chithunzi chopangidwa ndi lenzi yosiyana chimayendanso kutali ndi lenzi, koma chimakhala mkati mwa kutalika kwa focal.
7. funsoNgati chinthu chayikidwa pamalo owonekera a lenzi yosiyana, kodi chithunzicho chidzakhala kuti? yankho: Pa lenzi yosiyana, chithunzicho chidzapangidwabe mbali yomweyo ndi chinthucho ndipo chidzakhala chowoneka bwino, choyimirira, komanso chocheperako. Lingaliro loyika chinthu pamalo ofunikira siligwira ntchito mofanana ndi momwe limagwirira ntchito pa lenzi zolumikizana.
8. funsoKodi lenzi yosiyana ingapange chithunzi chozungulira? yankhoAyi, lenzi yosiyana nthawi zonse imapanga chithunzi choyimirira (kumanja-kutsogolo).
9. funsoKodi zinthu zomwe zili mu lenzi (galasi, pulasitiki, ndi zina zotero) zimakhudza mawonekedwe a chithunzi chopangidwa ndi lenzi yosiyana? yankho: Zinthu zomwe zili mu lens zimatha kusintha kutalika kwa focal chifukwa cha ma refractive indices osiyanasiyana, koma sizisintha makhalidwe ofunikira a chithunzi chomwe chimapangidwa ndi lens yosiyana. Chithunzicho chidzakhalabe chowoneka bwino, choyimirira, komanso chochepetsedwa.

10. Funso : Ngati lenzi yosinthasintha ili ndi kutalika kolunjika kolakwika, kodi izi zimakhudza bwanji kapangidwe ndi mawonekedwe a chithunzicho? Yankho : Kutalika kolunjika kolakwika kwa lenzi yosinthasintha kumasonyeza komwe kuwala kumapindika, koma sikusintha mawonekedwe a chithunzicho. Chithunzicho chidzakhalabe chowoneka bwino, choyimirira, komanso chochepetsedwa.
