RGB - he aha ka pono e ʻike?

ʻO ka spectrum o nā hawewe electromagnetic ma ka laulā mai 380 a 780 nanometers he nui nā wehewehe makemakika ma ke ʻano o kahi ākea kala ʻekolu. He mea nui kēia no ka mea e hana ana ka maka kanaka ma ʻaneʻi. I ka hana ʻana i nā kala ma nā pale a me nā mea nānā, hoʻohana ʻia ka ʻōnaehana RGB.

He aha ke kumu hoʻohālike RGB?

RGB - kekahi o nā hiʻohiʻona ākea kala nui e pili ana i ke kukui ʻike ʻia, mahalo i nā kala hiki ke hoʻopaʻa ʻia ma nā ʻano mea hoʻomālamalama kukui.

ʻO ka inoa ponoʻī kahi pōkole o nā leka mua o nā kala ʻekolu ma ka ʻōlelo Pelekania:

• R ʻulaʻula ke ʻano ʻulaʻula
• G - ʻōmaʻomaʻo, ʻo ia hoʻi. ʻōmaʻomaʻo
• B - uliuli, ʻo ia hoʻi ka uliuli

ʻO ka ʻōnaehana ka hopena o ka ʻike pololei o ke kala e ka maka kanaka. ʻO ka ʻoiaʻiʻo, hiki ke hōʻike pololei ʻia nā kala āpau i ʻike ʻia e ka maka ma muli o ka hoʻohui ʻana i nā kahe māmā i nā ʻāpana kūpono i kēia mau kala ʻekolu. Hoʻohana mua ʻia ke ʻano hoʻopaʻa leo RGB i nā polokalamu projection hou, ʻo ia hoʻi nā mākaʻikaʻi, nā pale LCD, nā pale kelepona a me nā papa papa, a me nā projectors. He hana maikaʻi nō hoʻi ia no nā mea ʻike e like me nā kāmela kikohoʻe a me nā scanners, a me ka ʻepekema kamepiula, ʻoiai ua kākau ʻia ka palette kala o ka hapa nui o nā faila ma RGB ma ke ʻano he 24-bit notation - 8 bits no kēlā me kēia ʻāpana.

Pehea e hana hou ʻia ai nā kala i ka ʻōnaehana RGB?

No ka loaʻa ʻana o nā kala ʻāpana i ka RGB, hoʻohana ʻia kahi ʻano hoʻohui hoʻohui, ʻo ia ka hana ʻana i nā kala hoʻokahi ma ka hui ʻana i nā kukui māmā me nā ikaika i koho pono ʻia. ʻO ka hopena, ʻike ʻia nā kiʻi like ʻole ma nā monitor a i ʻole nā ​​​​mea hana ʻē aʻe i ʻōlelo ʻia ma luna. I nā huaʻōlelo ʻē aʻe, i ka wā e hāʻule ai nā kukuna māmā o nā kala kumu ʻekolu ma luna o ka ʻili o ka pale, hana koke lākou i nā kala hou i hopu ʻia e ka maka kanaka, i hoʻopaʻa ʻia ma luna o kekahi. ʻO kēia ma muli o nā ʻano kikoʻī o ka maka, ʻaʻole hiki ke hoʻokaʻawale i waena o nā ʻāpana pākahi, akā ʻike pū ʻia lākou, e like me ke kala hou. Hele pololei nā kukuna o ka mālamalama i nā maka a ʻaʻole ʻike ʻia mai kekahi mea ma ke ala.

ʻO ka hoʻohui ʻana o nā mea ʻē aʻe i ka additive synthesis e loaʻa ana ma kahi ʻeleʻele ʻeleʻele, no ka mea ʻo ia ka hihia me nā monitor. He ʻokoʻa loa kēia ma mua o ke ʻano o ka palette kala CMYK, kahi o ke kua i ke kala keʻokeʻo o ka lau a hoʻohana ʻia iā ia ma ka uhi ʻana i nā ʻāpana me ke ʻano halftone. Hāʻawi ka hiʻohiʻona RGB i nā mea he nui, akā e hoʻomanaʻo ʻo nā mea i hoʻohana ʻia he kī nui i ka hana hou kala. Hiki i kēlā me kēia o lākou ke loaʻa nā hiʻohiʻona spectral like ʻole a no laila ʻokoʻa ka ʻike kala e pili ana i ka pale o nā maka.

Pehea e loaʻa ai kahi kala kikoʻī?

He mea pono e hoʻoikaika i kēlā me kēia kala i ka ʻōnaehana RGB hiki ke loaʻa kekahi waiwai mai 0 a 255, ʻo ia hoʻi. hōʻike ʻōlinolino o kekahi mau kala. Ke hoʻonoho ʻia ka ʻāpana i ka 0, ʻaʻole hiki i ka pale ke ʻā aʻe i kēlā kala. ʻO ka waiwai 255 ka ʻoi loa o ka mālamalama. No ka loaʻa ʻana o ka melemele, pono ʻo R a me G he 255 a he 0 ka B.

No ka loaʻa ʻana o ke kukui keʻokeʻo ma RGB, pono e hui pū ʻia nā kala ʻē aʻe i ka ikaika loa, ʻo ia hoʻi. nā kala ma nā ʻaoʻao ʻē aʻe - R, G a me B no laila he 255 ka waiwai. Loaʻa ka ʻeleʻele ma nā waiwai liʻiliʻi loa, ʻo ia. 0. ʻO Z, ʻo ia hoʻi, pono ke waihoʻoluʻu hina i kēlā me kēia ʻāpana i kahi waiwai i waenakonu o kēia unahi, ʻo ia. 128. No laila, ma ka hui 'ana i nā waiwai kala puka, hiki ke 'ike 'ia kekahi kala.

No ke aha i hoʻohana ʻia ai nā kala ʻulaʻula, ʻōmaʻomaʻo a me ka uliuli?

Ua kūkākūkā hapa ʻia kēia kumuhana. Ma hope o nā mea a pau, ʻaʻole ia he coincidence i hoʻohana ʻia kēia mau kala ʻekolu i kēia hiʻohiʻona, ʻaʻole nā ​​mea ʻē aʻe. Aia nā mea a pau i nā mana kiko'ī o ka maka kanaka. Loaʻa iā ia nā photoreceptors kūikawā o ka ʻike, ʻo ia hoʻi nā neurons retinal. I loko o ka pōʻaiapili o kēia mau noʻonoʻo, ʻo nā cones ke kuleana no ka ʻike photopic, ʻo ia hoʻi, ka ʻike o ke kala i ka mālamalama maikaʻi, he mea koʻikoʻi. Inā ʻoi aku ka ikaika o ka mālamalama, e emi ana ka naʻau o ka ʻike ma muli o ka saturation kiʻekiʻe o kēia mau neurons me ia.

No laila, ʻo nā suppositories e hoʻomoʻi i ka mālamalama me nā pae hawewe like ʻole, a no laila aia ʻekolu pūʻulu nui o nā suppositories - hōʻike kēlā me kēia o lākou i kahi ʻike kūikawā i kahi lōʻihi kikoʻī. ʻO ka hopena, ʻo nā nalu nalu ma kahi o 700 nm ke kuleana no ka ʻike ʻana i ka ʻulaʻula, ma kahi o 530 nm e hāʻawi i ka manaʻo o ka uliuli i ka ʻike, a ʻo nā nalu o 420 nm hāʻawi i ka ʻōmaʻomaʻo. ʻO ka palette kala waiwai ka hopena o ka pane ʻana o kēlā me kēia hui o nā suppositories i nā nalu ʻike ʻia o ka mālamalama.

Inā komo pololei ka mālamalama i loko o ke kino o ka hihiʻo a ʻaʻole i ʻike ʻia i kekahi mea ma kona ala, a laila hiki ke ʻike maʻalahi i kekahi mau kala, e hana ʻia ana ma nā monitor, nā pale, nā projectors a i ʻole nā ​​kāmera. Hoʻohana ʻia ka hana hoʻohui i ʻōlelo ʻia ma luna, ʻo ia ka hoʻohui ʻana i kēlā me kēia kala i kahi ʻeleʻele. He mea ʻē aʻe ke ʻike ka maka o ke kanaka i ka mālamalama. Ma ia kūlana, lilo ka ʻike o ke kala i ka hopena o ka absorption o nā hawewe electromagnetic o kekahi lōʻihi e ka mea. I loko o ka lolo kanaka, alakaʻi kēia i ke ʻano o kekahi kala. ʻO kēia ke kū'ē pololei o ke kumu hoʻohui, kahi e unuhi ʻia ai nā kala mai kahi keʻokeʻo.

Pehea e hoʻohana ʻia ai ka palette kala RGB?

He mea koʻikoʻi ka RGB i ka pōʻaiapili o nā hana e pili ana i ke kahua o ka Internet marketing. ʻO ka mea mua, ke kamaʻilio nei mākou e pili ana i ka hana ʻana i kahi papahana hoʻolālā pūnaewele a me nā hana ʻē aʻe a pau ma ka Pūnaewele e pili ana i ka hoʻohui ʻana i nā kiʻi a me nā kiʻi i nā ʻike i paʻi ʻia (e laʻa, ma nā ʻoihana pūnaewele), a me ka hana ʻana i nā kiʻi a i ʻole infographics. Me ka ʻole o ka ʻike kūpono i ka hana ʻana i nā kala i ke kumu hoʻohālike RGB, he mea paʻakikī ke hoʻokō i nā hopena ʻoluʻolu loa, ʻoiai ʻoi aku ka ʻokoʻa o kēlā me kēia kiʻi i nā mea uila. ʻO kahi hoʻololi maʻalahi i ka ʻōlinolino o ka pale ke kumu i ka ʻike ʻokoʻa o nā kala (ʻo ia ke kumu o ka naʻau o nā cones).

Pono e hoʻomanaʻo e pili ana nā hoʻonohonoho monitor i ka ʻike o nā kala a no laila i kekahi manawa he ʻokoʻa nui i nā aka. Mālama kēia ʻike i nā kuhi hewa he nui ma ka laina o nā kiʻi a me nā mea kūʻai aku. ʻO ia ke kumu he mea nui e ʻike i kahi papahana kikoʻī ma ka liʻiliʻi o kekahi mau monitor. A laila ʻoi aku ka maʻalahi o ka hoʻomaopopo ʻana i ka mea a ka poʻe e ʻike ai. ʻAʻohe pilikia, ma hope o ka ʻae ʻia, e hōʻike ʻokoʻa ka papahana iā ia iho, no ka mea, ua hoʻololi koke ka mea kūʻai aku i nā hoʻonohonoho monitor.

ʻO kahi ala i waho o ke kūlana ʻo ka hana pū ʻana me kahi mea hoʻolālā kiʻi i loaʻa kahi hāmeʻa maikaʻi e hiki ai iā ʻoe ke hōʻike maikaʻi i nā kala e pili ana i nā ʻāpana hoʻopuka. I ka manawa like, pono e hoʻokūpaʻa ʻia i ka hihia o nā huahana i paʻi ʻia, ʻaʻole kū mai ia mau pilikia. Ua lawa ka hoʻomākaukau ʻana i kahi paʻi hoʻāʻo ma mua e ʻike i ke ʻano maoli o ka holo holoʻokoʻa.
