Daniel Hruska I ka makahiki 2010, ua haʻaheo ʻo Steve Jobs i ka iPhone 4. Ma waho aʻe o kahi hoʻolālā hou loa, ua lawe mai ia i kahi hoʻonā hōʻike ʻike ʻole ʻia ma kahi polokalamu kelepona. Ma kahi ili me ka diagonal o 3,5 ″ (8,89 cm), Apple, a i ʻole kāna mea hōʻike hōʻike, hiki ke hoʻopili i kahi matrix o nā pika me nā ana o 640 × 960 a ʻo ka nui o kēia hōʻike he 326 PPI (pixels per inches) . E hele mai ana nā hōʻike maikaʻi no nā Mac?
ʻO ka mea mua, e wehewehe i ka huaʻōlelo "Retina display". Manaʻo ka poʻe he ʻano ʻano lepili kūʻai wale nō kēia a Apple i haku ai. ʻAe a ʻaʻole. Aia nā hōʻike hoʻonā kiʻekiʻe ma mua o ka iPhone 4, akā ʻaʻole lākou i hoʻohana ʻia i ka honua mea kūʻai. No ka laʻana, nā hōʻike i hoʻohana ʻia i ka radiology a me nā ʻano lāʻau lapaʻau ʻē aʻe, kahi i loaʻa ai nā kiko a me nā kikoʻī i ke kiʻi, e hoʻokō i nā density pixel hanohano i ka laulā. 508 a 750 PPI. Kūleʻa kēia mau waiwai i ka palena o ka ʻike kanaka i nā poʻe "ʻoi loa", e hiki ai ke hoʻokaʻawale ʻia kēia mau hōʻike. Papa I ʻo ia hoʻi nā hōʻike papa 1. ʻO ke kumu kūʻai o ia mau panela he kiʻekiʻe loa, no laila ʻaʻole mākou e ʻike iā lākou i ka uila uila no kekahi manawa.
Ke hoʻi nei i ka iPhone 4, e hoʻomanaʻo ʻoe i ka ʻōlelo a Apple: "ʻAʻole hiki i ka retina kanaka ke hoʻokaʻawale i nā pika pākahi ma nā density ma luna o 300 PPI." I kekahi mau pule i hala aku nei, ua hoʻolauna ʻia ke kolu o ka hanauna iPad me ka ʻelua o ka hoʻonā hōʻike i hoʻohālikelike ʻia i nā hanauna i hala. Ua hoʻonui ʻia ka 768 × 1024 mua i 1536 × 2048. Inā mākou e noʻonoʻo i ka nui diagonal o 9,7 ″ (22,89 cm), loaʻa iā mākou ka mānoanoa o 264 PPI. Eia nō naʻe, ʻōlelo ʻo Apple i kēia hōʻike ʻo Retina. Pehea e hiki ai kēia i ka wā ʻelua makahiki i hala aku nei ua ʻōlelo ʻo ia he pono ka nui ma luna o 300 PPI? Maʻalahi. Hoʻohana wale ʻia kēlā 300 PPI i nā kelepona paʻalima a i ʻole nā mea hana i paʻa i ka mamao like mai ka retina me ke kelepona paʻa. ʻO ka maʻamau, paʻa ka poʻe i ka iPad ma kahi mamao iki mai ko lākou mau maka ma mua o ka iPhone.
Inā mākou e hoʻonui i ka wehewehe ʻana o "Retina" ma kekahi ʻano, penei ke kani:"He hōʻike retina kahi hōʻike i hiki ʻole i nā mea hoʻohana ke hoʻokaʻawale i nā pika pākahi." E like me kā mākou e ʻike ai, nānā mākou i nā hōʻike like ʻole mai nā mamao like ʻole. Loaʻa iā mākou kahi mākaʻikaʻi papa nui i hoʻonohonoho ʻia he ʻumi mau kenimika mai ko mākou poʻo, no laila ʻaʻole pono ʻo 300 PPI e hoʻopunipuni i ko mākou mau maka. Ma ke ala like, e moe ana nā MacBook ma ka papaʻaina a i ʻole ma ka ʻūhā i kahi kokoke iki i nā maka ma mua o nā mākaʻikaʻi nui. Hiki iā mākou ke noʻonoʻo i nā televise a me nā mea hana ʻē aʻe ma ke ʻano like. Hiki ke ʻōlelo ʻia e loaʻa i kēlā me kēia ʻāpana o nā hōʻike e like me kā lākou hoʻohana ʻana i kahi palena kiko pixel. ʻO ka palena wale nō e pono ai kekahi e hoʻoholo ai, ʻo ka mamao wale nō mai nā maka a i ka hōʻike. Inā ʻoe i nānā i ke kī nui no ka wehe ʻana o ka iPad hou, ua loaʻa paha iā ʻoe kahi wehewehe pōkole mai Phil Schiller.
E like me ka ʻike ʻia, lawa ka 300 PPI no ka iPhone i paʻa ma kahi mamao o 10″ (kokoke. 25 knm) a me 264 PPI no ka iPad ma kahi mamao o 15″ (kokoke. 38 knm). Inā ʻike ʻia kēia mau mamao, ʻano like ka nui o nā pika o ka iPhone a me ka iPad mai ka manaʻo o ka mea nānā (a i ʻole liʻiliʻi a ʻike ʻole ʻia). Hiki iā mākou ke ʻike i kahi ʻano like ma ke ʻano. ʻAʻole ia he mea ʻē aʻe he lā eclipse. He 400 ka liʻiliʻi o ka mahina ma mua o ka Lā, akā i ka manawa like he 400 manawa kokoke i ka Honua. I ka wā o ka eclipse holoʻokoʻa, uhi wale ka mahina i ka ʻili a pau o ka Lā. Me ka ʻole o ka manaʻo ʻē aʻe, manaʻo paha mākou he like ka nui o kēia mau kino ʻelua. Eia naʻe, ua haʻalele wau i ka uila, akā ua kōkua paha kēia hiʻohiʻona iā ʻoe e hoʻomaopopo i ka pilikia - nā mea mamao.
Ua holo ʻo Richard Gaywood o TUAW i kāna helu ʻana, me ka hoʻohana ʻana i ke ʻano helu makemakika e like me ke kiʻi mai ka keynote. ʻOiai ua manaʻo ʻo ia i ka mamao o ka nānā ʻana iā ia iho (11″ no ka iPhone a me 16″ no ka iPad), ʻaʻohe hopena o kēia ʻoiaʻiʻo i ka hopena. Akā ʻo ka mea hiki ke noʻonoʻo e pili ana i ka mamao o nā maka mai ka ʻili nui o ka 27-inch iMac. Hoʻololi kēlā me kēia kanaka i kā lākou wahi hana i ko lākou pono, a pēlā nō hoʻi i ka mamao mai ka monitor. He ʻoi aku ka lōʻihi o ka lima, akā eia hou - ʻoi aku ka lōʻihi o ka lima o ke kanaka ʻōpio ʻelua mika ma mua o ka wahine liʻiliʻi. I ka papa ma lalo o kēia paukū, ua hōʻike au i nā lālani me nā waiwai o ka 27-inch iMac, kahi āu e ʻike maopopo ai i ka nui o ka mamao e hana ai. ʻAʻole noho pololei ke kanaka ma luna o ka noho i ka lā a pau ma ke kamepiula, akā makemake ʻo ia e hilinaʻi i kona kuʻekuʻe ma luna o ka papaʻaina, kahi e waiho ai kona poʻo i kahi mamao liʻiliʻi mai ka hōʻike.
He aha ka mea hiki ke heluhelu hou ʻia mai ka papa ma luna? ʻAʻole ʻino loa nā lolouila apple a hiki i kēia lā. No ka laʻana, hiki ke wehewehe ʻia ka hōʻike o kahi MacBook Pro 17-inch ma ke ʻano he "retina" ma kahi mamao o 66 cm. Akā e lawe mākou i ka iMac me kahi pale 27" i ka hōʻike hou. Ma ke kumumanaʻo, e lawa wale nō ka hoʻonui ʻana i ka hoʻonā i ka liʻiliʻi ma mua o 3200 × 2000, ʻoiaʻiʻo nō kekahi holomua, akā mai ka manaʻo o ke kūʻai aku, ʻaʻole ia he "WOW hopena". Pēlā nō, ʻaʻole pono nā hōʻike MacBook Air i ka piʻi nui o ka helu o nā pika.
A laila aia kekahi koho hoʻopaʻapaʻa hou aʻe - pālua hoʻonā. Ua hele ma ka iPhone, iPod touch, a me ka iPad hou. Makemake ʻoe i ka 13-inch MacBook Air a me Pro me 2560 x 1600 hoʻonā hōʻike? E mau ana nā mea GUI a pau i ka nui like, akā e hana maikaʻi ʻia. Pehea e pili ana i nā iMac me 3840 x 2160 a me 5120 x 2800 hoʻonā? He mea hoʻowalewale loa kēlā, ʻaʻole anei? Ke piʻi mau nei ka wikiwiki a me ka hana o nā kamepiula o kēia mau lā. ʻO ka pilina pūnaewele (ma ka liʻiliʻi ma ka home) hiki i ka ʻumi a hiki i nā haneli megabits. Ke hoʻomaka nei nā SSD e hoʻoneʻe i nā paʻakikī paʻakikī, a laila e hoʻonui wikiwiki i ka pane o ka ʻōnaehana hana a me nā noi. A me nā hōʻike? Ma waho aʻe o ka hoʻohana ʻana i nā ʻenehana hou, e mau ana kā lākou hoʻoholo no nā makahiki he nui. Ua hoʻopaʻi ʻia paha ke kanaka e nānā i ke kiʻi paʻi no ka manawa pau ʻole? ʻAʻole loa. Ua hiki iā mākou ke hoʻopau i kēia maʻi ma nā polokalamu kelepona. I kēia manawa kūpono pono ʻO nā kamepiula kamepiula a me nā lolouila e hiki mai ana ma hope.
Ma mua o ka hoʻopaʻapaʻa ʻana he mea ʻole kēia a ua lawa nā ʻōlelo hoʻoholo o kēia lā - ʻaʻole lākou. Inā ʻoluʻolu mākou i ke kūlana o kēia manawa, ʻaʻole paha mākou e puka i waho o nā ana. He wahi mau no ka hoʻomaikaʻi ʻana. Hoʻomanaʻo nui wau i nā hopena ma hope o ka hoʻomaka ʻana o ka iPhone 4, no ka laʻana: "No ke aha e pono ai iaʻu kahi hoʻonā i kaʻu kelepona paʻa?" ʻAʻole pono, akā ʻoi aku ka maikaʻi o ke kiʻi. A ʻo ia ke kumu. Hana i nā pixels i ʻike ʻole ʻia a hoʻokokoke i ke kiʻi pale i ka honua maoli. ʻO ia ka mea e hana nei ma ʻaneʻi. ʻO ke kiʻi i hoʻomaʻemaʻe ʻia ke nānā aku i ka ʻoluʻolu a kūlohelohe i ko mākou mau maka.
He aha ka mea i nalowale iā Apple e hoʻolauna i nā hōʻike maikaʻi? ʻO ka mea mua, ʻo nā panela iā lākou iho. ʻAʻole pilikia ka hana ʻana i nā hōʻike me nā hoʻonā o 2560 x 1600, 3840 x 2160 a i ʻole 5120 x 2800 i kēia mau lā. Ke waiho nei ka nīnau he aha kā lākou mau kumukūʻai hana i kēia manawa a he mea kūpono paha ia no Apple e hoʻokomo i kēlā mau panela i kēia makahiki. He hanauna hou o nā mea hana Ive Bridge ua mākaukau mua ia no nā hōʻike me ka hoʻonā o 2560 × 1600. Ua loaʻa iā Apple ka mana e pono ai e hana i nā hōʻike retina, ma ka liʻiliʻi loa e pili ana i nā MacBooks.
Me ka ʻelua o ka hoʻonā ʻana, hiki iā mākou ke manaʻo ʻelua i ka hoʻohana ʻana i ka mana, e like me ka iPad hou. Ua kaena ʻo MacBooks i kahi paʻa paʻa loa no nā makahiki he nui, a ʻaʻole e haʻalele ʻo Apple i kēia pono i ka wā e hiki mai ana. ʻO ka hoʻonā e hoʻemi mau i ka hoʻohana ʻana i nā ʻāpana o loko, akā ʻo ka mea nui loa - e hoʻonui i ka mana pākaukau. Me he mea lā ua hoʻopau ʻia kēia pilikia. ʻO ka iPad hou komo pū me kahi pākaukau, ʻaneʻane like nā ʻāpana kino e like me ka pākaukau iPad 2 a he 70% kiʻekiʻe. Hiki ke manaʻo ʻia e makemake pū ʻo Apple e hāʻawi iā ia i nā polokalamu kelepona ʻē aʻe.
Loaʻa iā mākou ka lako pono, pehea ka polokalamu? I mea e ʻoi aku ka maikaʻi o nā noi i nā hoʻonā kiʻekiʻe, pono e hoʻololi iki ʻia lākou. ʻO kekahi mau mahina i hala aku nei, ua hōʻike ʻo Xcode a me OS X Lion beta i nā hōʻailona o ka hōʻea ʻana o nā hōʻike retina. Ma kahi puka aniani maʻalahi, hele ʻo ia e hoʻohuli i ka mea i kapa ʻia ʻo "HiDPI mode", i pālua i ka hoʻonā. ʻOiaʻiʻo, ʻaʻole hiki i ka mea hoʻohana ke nānā i nā loli i nā hōʻike o kēia manawa, akā ʻo kēia hiki ke hōʻike e hoʻāʻo nei ʻo Apple i nā prototypes MacBook me nā hōʻike retina. A laila, ʻoiaʻiʻo, pono e hele mai nā mea hoʻomohala o nā noi ʻaoʻao ʻekolu a hoʻololi hou i kā lākou hana.
He aha kou manaʻo e pili ana i nā hōʻike maikaʻi? Ke manaʻoʻiʻo nei au e hiki mai ana ko lākou manawa. I kēia makahiki, hiki iaʻu ke noʻonoʻo i ka MacBook Air a me Pro me ka hoʻonā ʻana o 2560 x 1600. ʻAʻole wale lākou e maʻalahi i ka hana ʻana ma mua o nā monsters 27-inch, akā ʻo ka mea nui loa ʻo lākou ka hapa nui o nā kamepiula Apple i kūʻai ʻia. ʻO nā MacBook me nā hōʻike retina e hōʻike i kahi lele nui ma mua o ka hoʻokūkū. ʻO ka ʻoiaʻiʻo, e lilo lākou i mea lanakila ʻole no kekahi manawa.
ʻatikala maikaʻi loa! Mai ka wā i loaʻa ai iaʻu ka iPhone 4, ua ʻeha ka nānā ʻana i kēlā mau rasters nui. Ma kaʻu MacBook, 1280x800 pōʻino loa. Ke loaʻa iaʻu kahi huila hoʻolaha no nā leka uila a i ʻole nā hōʻano hou i ka hale kūʻai app ma ka dock, ʻaʻole hiki iaʻu ke ʻike i ke ʻano o ia helu - ʻo ka helu "4" i hana ʻia me 10 pixels ʻaʻole hiki ke ʻike ʻia. ʻO nā hōʻike Retina ma MacBooks he mea nui a, ma luna o nā mea āpau, pono ka holomua, kahi aʻu e kali nei.
ʻAe loa wau. Ma kaʻu 24 ″ monitor me ka hoʻonā FullHD, ʻike ʻia nā ʻōkuhi a i kekahi manawa pono wau e koho i ka helu.
"Loaʻa i ka iPad hou kahi pākaukau ʻaneʻane like nā ʻano kino..." ʻaʻole pono anei e nui aʻe nā ana "kino"?
ʻOiaʻiʻo, mahalo no nā poʻo i luna.
ʻAʻole makemake wau e ʻeli, akā ʻaʻohe o nā mea i haʻi ʻia i ka hoʻonā ʻana o 4x, akā 2x wale nō. Inā he 4x, aia ka ipad hou i 4096 × 3072, he mea maikaʻi loa ia, akā i ka ʻoiaʻiʻo he hoʻonā. 2x kiʻekiʻe ma mua o ka mea kumu, a me ka iPhone a me ka iPod Touch. A i ʻole, manaʻo wau e hele mai ʻo Apple me kēia, ʻo ia hoʻi ke kumu i kūʻai ai au i ka 13 ″ Air a ʻaʻole ka Pro no ka mea ʻoi aku ka maikaʻi o ka Air.
Hiki iā ʻoe ke ʻeli, akā ʻaʻole pono ʻoe. Lawe ʻia ia e ka helu o nā pika - ʻo ka iPhone kahiko 320 x 480 = 153 a me ka iPhone hou 600 x 640 = 960, ʻo ka iPad kahiko 614 x 400 = 1024 760 a me ka iPad hou 7782 x 40 = 2048, ʻo ia ka 1536. ka nui o na manawa . :)
ʻAe, ʻo ka helu o nā pika he mea ʻē aʻe a ʻo ka hoʻonā ponoʻī ʻē aʻe;) ʻo ka hoʻonā ʻana he 2x kēlā a ʻo Apple ponoʻī e ʻōlelo pēlā a ʻo ka helu o nā pika he 4x kēlā, akā ua huikau ka ʻatikala i ka hoʻonā a me ka helu o nā pika a ʻo ia. lapuwale. I ka hopena, ʻae, ʻo ia ka hihia ua pālua ʻia kēlā me kēia mea hoʻonā, no laila ua pālua ka hoʻonā i nā helu (1024 × 2 = 2048 a me 768 × 2 = 1536 a no ka mea he 2x mea i hoʻonui ʻia e 2x. , no laila, ma ka hope o ka helu o nā pika he 2 × 2 e pili ana i ka helu ʻana o kēia helu 1024×768 ʻo ia hoʻi mai ka helu (1024×2)x(768×2) = X inā mākou e wehe i nā mea hoʻonā a laila X = 4 inā ʻaʻole X = 3,1MPix) ua kuhi hewa lākou ma ʻaneʻi he 2 ʻāpana, ʻo ia hoʻi ka ʻāpana a i ʻole ka ʻāpana like (helu o nā pika) a me ke kiʻekiʻe/ākea, ʻo ia ka hoʻonā.

Ae, pololei 'oe. ʻAʻole like ka hoʻoholo ʻana me ka helu o nā pika.
