Kuzvisarudzira TV iwe, mudiwa wako, kubva pakuona kwesainzi, kwete kushambadzira

Mhoroi munhu wese.

Ndakakurudzirwa kunyora chinyorwa ichi chipfupi nekukakavadzana maererano nesarudzo yeTV.

Iye zvino munzvimbo ino - pamwe ne "megapixels emakamera" - kune bacchanalia yekushambadzira mukutsvaga kugadzirisa: HD Ready yakagara yakatsiviwa neFull HD, uye 4K uye kunyange 8K yave kutowedzera kufarirwa.

Ngatizvione - chii chatinonyatsoda?

Kosi yejiometry yechikoro uye imwe ruzivo rwekutanga kubva kuWikipedia ichatibatsira neizvi.

Saka maererano iyi Wikipedia chaizvo, ziso rakashama remunhu wepakati chinhu chakasiyana chinokwanisa kuona panguva imwe chete nzvimbo pakona ye130 ° -160 °, pamwe chete nekusiyanisa zvinhu pakona ye 1-2′ (inenge 0,02 ° -0,03 °) . Wherein Kukurumidza kutarisa kunoitika kure nemasendimita gumi (vechidiki) - 10 cm (vanhu vazhinji vane makore makumi mashanu zvichikwira) kusvika kusingagumi.

Zvinotaridzika zvakanaka. Kutaura zvazviri, hazvisi nyore kudaro.

Pazasi pane munda wekuona ziso rekurudyi remunhu (perimetric kadhi, nhamba pachiyero madhigirii angular).

Nzvimbo yeorenji ndiyo nzvimbo yekufungidzira ye fundus blind spot. Munda wekuona weziso hauna chimiro chedenderedzwa renguva dzose, nekuda kwekuganhurwa kwekutarisa nemhino padivi repakati uye eyelids kumusoro uye pasi.

Kana isu superimpose mufananidzo wekurudyi uye kuruboshwe maziso, tinowana chinhu chakadai:


Sezvineiwo, ziso remunhu haripi iwo hunhu hwakafanana hwekuona mhiri kwendege yese pakona yakakura. Hongu, nemaziso maviri tinogona kuziva zvinhu zviri mukati mekuvhara kwe180 ° pamberi pedu, asi tinogona kuzviziva se-dimensional matatu chete mukati me110 ° (kunzvimbo yakasvibirira), uye seyakazara-ruvara - mune imwe nhanho. diki renji re60 ° -70 ° (kunzvimbo yebhuruu). Hongu, dzimwe shiri dzine munda wekuona dzinenge 360 ​​°, asi isu tine zvatinazvo.

Saka tinozviwana munhu anogamuchira mufananidzo wepamusoro-soro pakona yekuona ye60 ° -70 °. Kana kufukidza kukuru kuchidikanwa, tinomanikidzwa "kumhanyisa" maziso edu pamufananidzo.

Iye zvino - nezvemaTV. Nekumisikidza, funga maTV ane anonyanya kufarirwa hupamhi-kusvika-urefu reshiyo se16: 9, pamwe neflat screen.

Kureva kuti, zvinobuda kuti W: L = 16:9, uye D ndiyo diagonal.

Saka, tichirangarira Mutemo wePythagorean:


Saka, tichifunga kuti mhinduro ndeiyi:

• HD Yakagadzirira 1280x720 pixels
• Full HD ine 1920x1080 pixels
• Ultra HD 4K ine 3840x2160 pixels,

tinoona kuti pixel side iri:

• HD Yakagadzirira: D/720,88
• Full HD: D/2202,91
• Ultra HD 4K: D/4405,81

Kuverengera kwezvinokosha izvi zvinogona kuwanikwa pano

Iye zvino ngativerengei yakaringana chinhambwe kune iyo skrini kuitira kuti ziso rivhare mufananidzo wese.

Kubva pamufananidzo zviri pachena kuti


Sezvo iyo yakakura parameter yehurefu uye hupamhi hwemufananidzo iri hupamhi - uye ziso rinoda kuvhara hupamhi hwese kwechidzitiro - ngativerengei yakaringana chinhambwe kuenda kuchiratidziro, tichifunga kuti, sezvaratidzwa pamusoro, kona yekuona. haifaniri kudarika 70 degrees:

Ndiko kuti: Kuti ziso rivhare hupamhi hwese kwechidzitiro, isu tinofanirwa kunge tiri chinhambwe kwete padyo kupfuura hafu yediagonal yechidzitiro.. Uyezve, chinhambwe ichi chinofanirwa kunge chiri 50 cm kuti ive nechokwadi chekugadzika kutarisa kune vanhu vezera ripi zvaro. Ngatirangarirei izvi.

Zvino ngativerengei chinhambwe icho munhu achasiyanisa mapikseli pachiratidziri. Iyi ndiyo gonyotatu imwechete ine tangent yekona, R chete mune ino kesi saizi yepixel:

Kureva kuti: kure kure kupfuura 2873,6 pixel saizi, ziso harizooni zviyo. Izvi zvinoreva, uchifunga nezve kuverengerwa kwepixel divi riri pamusoro, iwe unofanirwa kunge uri pane inotevera diki chinhambwe kubva pachiratidziro kuti mufananidzo uve wakajairika:

• HD Yakagadzirira: D/720,88 x 2873,6 = 4D, kureva mana diagonals
• Full HD: D/2202,91 x 2873,6 = 1,3D, kureva, ingangoita isingasviki imwe nehafu sikirini diagonals
• Ultra HD 4K: D/4405,81 x 2873,6 = 0,65D, kureva kuti, inopfuura hafu yechidzitiro diagonal

Uye zvino izvo zvese zvakatungamira kune -

Mhedziso:

1. Iwe haufanirwe kugara padyo ne50 cm kune iyo skrini - ziso harizokwanisa kutarisa pamufananidzo kazhinji.
2. Iwe haufanirwe kugara padhuze kupfuura 0,63 skrini diagonals - maziso ako achaneta nekuti achafanirwa kumhanya achitenderedza mufananidzo.
3. Kana ukaronga kuona TV uri chinhambwe chinodarika mana skrini diagonals, haufanirwe kutenga chimwe chinhu chinotonhorera kupfuura HD Yakagadzirira - hauzooni mutsauko.
4. Kana ukaronga kuona TV uri chinhambwe chinopfuura imwe nehafu chidzitiro diagonals, haufanirwe kutenga chimwe chinhu chinotonhorera kupfuura Full HD - hauone mutsauko.
5. Kushandisa 4K kunongodiwa chete kana iwe ukatarisa skrini iri chinhambwe chisingasviki imwe nehafu diagonals, asi inopfuura hafu yediagonal. Pamwe aya ndiwo mamwe emhando yemamonitor emitambo yemakomputa kana mapaneru makuru, kana chigaro chakamira padyo neTV.
6. Kushandisa sarudzo yepamusoro haina musoro - iwe haungaoni mutsauko ne4K, kana iwe unenge uri padyo nechidzitiro uye kona yekuona haizovhare iyo ndege yese (ona pfungwa 2 pamusoro). Dambudziko rinogona kugadziriswa zvishoma neyakakombama skrini - asi kuverenga (zvakanyanya kuoma) kunoratidza kuti kuwana uku hakuna chokwadi.

Iye zvino ini ndinokurudzira kuyera imba yako, nzvimbo yesofa yako yaunofarira, diagonal yeTV uye kufunga: zvine musoro here kubhadhara zvakawanda?
