Hangarau Hanga Pouaka Whakaata me ngā Āheinga 3D
I mua, ko te pouaka whakaata 3D tētahi o ngā auahatanga tino whakahihiri i roto i te umanga hikohiko kaihoko. Ko te whakaaro ki te whakaatu i ngā whakaahua e ahua "peke atu ana i te mata" he hohonu rānei nō te ao tūturu i akiaki i ngā kaihanga pouaka whakaata ki te whakataetae ki te whakawhanake i ngā hangarau panera, te tukatuka whakaahua, tae atu ki ngā taputapu tautoko pērā i ngā mōhiti motuhake. Ahakoa kua heke te rongonui o te pouaka whakaata 3D i te mākete kāinga, he mea nui tonu kia mārama ki te hangarau kei muri i a ia, nā te mea koinei te pūtake mō ngā whanaketanga tirohanga hou - mai i ngā pane VR ki ētahi atu tikanga whakaaturanga rumaki. Ka matapakihia e tēnei tuhinga te hangarau kei muri i ngā pouaka whakaata 3D, ō rātou mātāpono mahi, ngā wāhanga matua, me ngā wero e pā ana ki a rātou.
Ngā Mātāpono Taketake o te Tirohanga 3D
Ka kitea e te tangata te hohonutanga nā te mea ka kitea e ngā kanohi e rua ngā whakaahua mai i ngā koki rerekē. Ka kiia tēnei rerekētanga iti ko te stereopsis. Ka whakamahia e te pouaka whakaata 3D tēnei mātāpono mā te whakaatu i ngā whakaahua rerekē e rua: tētahi mō te kanohi maui, tētahi mō te kanohi matau. Kātahi ka whakakotahi te roro i ngā mea e rua hei hanga i tētahi tirohanga hohonutanga.
Kia angitu ai tēnei mahi tinihanga, me whakarite te pouaka whakaata kia whiwhi ia kanohi i te ahua tika me te kore e nui rawa te " turuturu" ki tētahi atu kanohi. E mōhiotia ana tēnei turuturu ko te crosstalk, ko te ghosting rānei, ā, ko tētahi o ngā raruraru matua o ngā pouaka whakaata 3D.
Ngā Huarahi Matua e Rua: Te 3D Kaha me te 3D Pāhekoheko
I roto i te hītori o ngā pouaka whakaata 3D kāinga, e rua ngā tikanga tino rongonui: te 3D kaha (arai kaha) me te 3D kore mahi (polarized). E arotahi ana ēnei e rua ki te wehenga whakaahua maui-matau, engari he rerekē ngā tikanga e whakamahia ana.
1) Pouaka Whakaata 3D Hohe (Katiaki Hohe)
I roto i tētahi pūnaha hohe, ka whakaatuhia e te pouaka whakaata ngā whakaahua maui me te matau i tētahi tere tino teitei (hei tauira, 120 Hz, neke atu rānei). Ka mau te kaimātakitaki i ngā mōhiti kati hohe, ā, ka taea e ngā karāhe te whakapōuri me te whakamārama i te wā kotahi: ina whakaaturia te whakaahua mō te kanohi maui, ka whakapōuri te karāhe matau, ā, ka pērā anō hoki.
Ngā wāhanga matua o tētahi pūnaha hohe:
– He panera he tere whakahou teitei (ko te tikanga he 120/240 Hz) kia kore ai e kitea he kimokimo ngā huringa anga.
– Pūnaha tukutahitanga (whero, Nihokikorangi, RF rānei) i waenga i te pouaka whakaata me ngā karāhe.
– He tukatuka ataata e āhei ana ki te whakahaere i te raupapatanga anga me te pupuri i te wā tika.
Te taikaha:
– He teitei ake te taumira mō ia kanohi nā te mea ka taea e ia kanohi te whiwhi i te anga katoa (i runga i te papa me te tikanga tukatuka).
– Ka kitea te kaha o te pānga hōhonutanga mēnā he tika ngā tautuhinga.
Te korenga:
– He nui ake te utu mō ngā mōhiti, me whakamahi pākahiko, ā, he taumaha hoki.
– Mōrearea o te kimokimo, te ngenge rānei o te kanohi mēnā kāore i te pumau te tukutahitanga.
– Tērā pea ka piki ake te whakawhitiwhiti kōrero mēnā he puhoi te urupare a te rōpū.
2) Pouaka Whakaata 3D Korekore (Polarized)
I roto i tētahi pūnaha kore aro, ka whakaatuhia e te pouaka whakaata ngā whakaahua e rua i te wā kotahi, engari he rerekē te whakapūtātanga o aua whakaahua. He karāhe whakapūtātanga ngā karāhe kore aro e tātari ana kia kotahi anake te whakaahua e kitea ana e te kanohi maui, ā, ka kite te kanohi matau i tētahi atu.
He maha ngā pouaka whakaata 3D LCD kore e whakamahi ana i te tikanga Film Patterned Retarder (FPR): ka pania he paparanga kiriata whakapōraru ki te mata o te panera hei whakaputa i ngā tauira rārangi whakapōraru rerekē i runga i ngā rarangi pika tauhou me ngā rarangi pika taurite. Nō reira, ka whiwhi tetahi kanohi i tētahi rarangi, ka whiwhi tetahi atu kanohi i tētahi rarangi rerekē.
Te taikaha:
– He mōhiti māmā, iti te utu, kāore he pākahiko.
– He pai ake te whakamahi mō te wā roa.
Te korenga:
– I roto i ngā whakatinanatanga FPR, ka taea te whakaiti i te taumira poutū whai hua mō ia kanohi (hei tauira, mai i te 1080p ki te ōrite o te 540p mō ia kanohi) nā te wehenga rarangi.
– Tērā pea ka heke te koi me te taipitopito, inā koa i ngā tawhiti tiro tata.
Hangarau Paewhiri: LCD/LED vs Plasma vs OLED
Ko te angitu o tētahi pouaka whakaata 3D he nui te awe o ngā āhuatanga o te panera, inā koa te urupare pika me te kaha ki te whakaatu i ngā anga tere.
LCD / LED
Ko te LCD (me te rama LED) te mea nui rawa atu i te mākete pouaka whakaata. Mō te 3D hohe, me:
– He tere te urupare kia kore ai e waiho he tohu o ngā whakawhiti whakaahua (te pōuri o te nekehanga) ka whakanui ake i te whakawhitiwhiti kōrero.
– Mā te matawai i te rama whakamuri, mā te rama whakamuri rānei e whakanui ake te koi o ngā nekehanga me te whakaiti i te turuturu i waenga i ngā anga.
Mō te 3D kore mahi, he pai ngā LCD nā te mea he ngāwari noa te whakamahi i ngā kiriata whakapolarizing. Heoi, ko te kounga 3D e whakawhirinaki ana ki te tika o te whakaritenga kiriata FPR me te ōritetanga o te panera.
wē
I mua, i rongonui a Plasma mō tōna tere o te urupare me te nekehanga maeneene mō te 3D hohe. Heoi, he nui ake te hiahia ki te hiko i tēnei hangarau, ā, he maha ngā kaihanga i mutu ai.
OLED
He tino tere te urupare pika a ngā OLED, he teitei te rerekētanga, ā, kāore e hiahiatia he whakamārama rama. I roto i te ariā, he pai tēnei mō te 3D hohe nā te mea ka whakaiti i te whakawhitiwhiti kōrero. Heoi, kāore anō kia horapa whānuitia ngā pouaka whakaata OLED 3D kāinga i te mea kua neke haere ngā au o te mākete ki te 4K, HDR, me ngā ratonga roma, kaua ki te 3D.
Te Tukanga Whakaputa me te Tukatuka Ihirangi i runga i te Pouaka Whakaata
Kia mahi ai te pouaka whakaata 3D, me whakarato ngā ihirangi 3D i roto i tētahi hōputu e tika ana. Ko ētahi hōputu noa ko:
– Te Tākai Anga: e rua ngā anga (maui me matau) kua tākai katoatia, e whakamahia ana i runga i te Blu-ray 3D.
– Taha-ki-te-taha (SBS): kua whakaritea ngā whakaahua maui me te matau ki te taha kotahi i roto i te anga kotahi (kua pēhia te taumira o ia whakaahua).
– Runga-me-Raro (RIP): ka whakarārangihia ngā whakaahua mai i runga ki raro.
He pūtukatuka ataata kei ngā pouaka whakaata 3D e:
1. Kimihia te hōputu ihirangi.
2. Wehewehea, wetewetehia rānei ngā raraunga ki ngā tirohanga mauī me ngā tirohanga matau.
3. Tukutahitia te putanga ki te pūnaha 3D (kaha, kore rānei).
4. Whakahaerehia te whakawhanuitanga nekehanga, te tauine, me te whakatika tae—he maha ngā wā e hiahiatia ana he whakatikatika kia kanapa tonu te ahua nā te mea ka whakaitihia e te pūnaha 3D (ina koa ko ngā mōhiti) te kanapa.
Ngā Wero Hangarau i roto i te Hanga Pouaka Whakaata 3D
Ehara i te mea ko te tāpiri noa i tētahi "aratau 3D" te waihanga i tētahi pouaka whakaata 3D. He nui ngā wero e pā ana ki ngā utu whakaputa me te wheako kaiwhakamahi:
1. Ka heke te kanapa
Ka whakaitihia e ngā mōhiti 3D—ngā mōhiti kaha me ngā mōhiti kore mahi—te nui o te mārama e tae atu ana ki ngā kanohi. Nō reira, me kaha ngā pouaka whakaata ki te whakaputa i te kanapa teitei ake, ki te arotau rānei i te papamuri kia mau tonu ai te kanapa o te ahua.
2. Whakawhitiwhiti Kōrero/Pūrua
Ina kore e tino tika te wehenga o te ahua maui-matau, ka puta ngā atarangi takirua. Tērā pea nā te puhoi o te urupare a te panera, te koretake o te tukutahitanga, te koretake rānei o te kounga o te tātari whakapūmau.
3. Te whakamarie me te hauora o ngā kanohi
Ka taea e te rerekētanga o te arotahi (te arotahi o te kanohi ki te mata 2D) me te huihuinga (te "arataki" a te roro i te kanohi ki te kite i te hohonu) te whakararu i te ngenge. Ka whakawhanakehia e ngā kaihanga ngā tautuhinga whakahaere hohonu me ngā tawhiti tirohanga kua tūtohutia.
4. Ngā paerewa me te hototahitanga
Ko te whānuitanga o ngā whakatakotoranga 3D e hiahia ana kia ngāwari ngā taputapu. Hei tāpiri, he maha ngā wā kāore e hototahi ngā mōhiti hohe puta noa i ngā waitohu nā te rerekētanga o ngā kawa tukutahi.
5. Ngā utu hanga
Ka piki ake ngā utu whakaputa mā ngā panera whakahou-teitei, ngā kiriata whakaporotaka tino tika, me ngā tukatuka ataata kaha ake. I te hekenga o te tono mākete, ka iti haere te whakaputanga, ā, ka uaua haere te whakaiti i ngā utu.
Tukanga Hanga: Mai i te Papaaho ki te Whakatikatika 3D
Hei whakarāpopototanga, ko te hanga i tētahi pouaka whakaata 3D e whai ake nei ngā mahi nui:
1. Te hoahoa o te papaaho me te taraiwa
Ka tohua e ngā miihini te tere whakahou, te wā urupare, me ngā ara iahiko taraiwa hei whakahaere i ngā pika me te wā anga. Mēnā ka whakahohea te 3D, he mea nui te whakaritenga tere whakahou.
2. Whakaurunga paparanga whatu
Mō te FPR 3D kore mahi, ka whakamahia te kiriata whakapōrearea tauira me te tino tika hei whakahāngai i ngā rārangi whakapōrearea ki ngā rarangi pika. Mā te hapa iti ka heke te kounga 3D.
3. Whakahaere rama whakamuri me te kanapa
I roto i te LED-LCD, ka arotauhia te pūnaha whakamārama (hei tauira, te whakaitiiti ā-rohe, te whakamārama matawai rānei) hei whakataurite i te kanapa, te rerekētanga, me te koi o ngā nekehanga.
4. Pūmanawa tukatuka 3D
Kua whakawhanakehia, kua whakamatautauria hoki ngā tikanga mō te wehenga anga, te tukutahitanga, te whakatikatika gamma, me te whakaiti i te whakawhitiwhiti kōrero. Ka whakatinanahia e ētahi kaihanga te whakatikatika mā te whakamahi i ngā anga "anti-ghosting" hei whakaiti i te turuturu whatu.
5. Te whakahaere kounga
Ka whakahaerehia e te wheketere ngā whakamātautau:
– taumata whakawhitiwhiti kōrero,
– te ōritetanga o te pōraritanga (koretake),
– te whakaroa tukutahi (kaha),
– te ōritetanga o te tae me te kanapa i waenga i ngā aratau 2D me te 3D.
He aha te take e memeha haere ai ngā pouaka whakaata 3D i te mākete?
Ahakoa he whakahihiri te hangarau, he maha ngā āhuatanga kua heke ai te rongonui o te pouaka whakaata 3D:
– He iti noa iho ngā ihirangi 3D, ā, he koretake te kounga.
– Me mau mōhiti ngā kaiwhakamahi, he mea kāore e tika ana tēnei.
– Kei te neke haere te ia o te umanga ki ngā whakapainga "ka kitea wawetia" pēnei i te 4K, HDR, me ngā mata nunui.
– He tokomaha ngā kaihoko e whakaaro ana he pai ake te 3D mō te whare pikitia i te rūma noho.
Te Katinga
Ko te hangarau kei muri i ngā pouaka whakaata 3D he huinga matatini o ngā whatu, ngā hikohiko panera, me te tukatuka ataata. Ko ngā pūnaha 3D hohe e whakawhirinaki ana ki ngā tere whakahou teitei me te tukutahitanga o ngā karu, ko te 3D kore mahi e whakawhirinaki ana ki ngā paninga polarization me ngā paninga whatu pēnei i te FPR. E rua ngā mea e pāngia ana e ngā wero pēnei i te whakahekenga kanapa, te whakawhitiwhiti kōrero, me te whakamarie o te kanohi. Ahakoa kāore ngā pouaka whakaata 3D i te āhuatanga matua i roto i te mākete hou, ko te rangahau me te whanaketanga i puta i te wā 3D kua whakarei ake i te hangarau whakaaturanga, ā, kua whakatakoto i te turanga mō ngā auahatanga tirohanga rumaki e tupu tonu ana i ēnei rā.
Ki te hiahia koe, ka taea e au te whakarerekē i tēnei tuhinga kia 1000 kupu tonu (nā te mea ka rerekē pea te maha o ngā kupu i runga i te āhua o te tatau), ka taea rānei te whakawhānui ake i te wāhanga "tukanga hanga" me ētahi atu taipitopito hangarau pēnei i ngā tūtohi rere whakaputa me ngā wāhanga matua (T-Con, IC taraiwa, pūnaha whakamārama, me te paipa tukatuka ataata).
