Canon 75-megapixel DSLR pahupaʻiwikiō e hiʻona ai Foveon-like mīkiniʻimi

ʻO kā Canon 75-megapixel DSLR pahupaʻi leo pahupaʻiwikiō e hōʻike ana i kahi sensor multilayer non-Bayer, i hoʻopaʻa ʻia e ka hui Kepani i kēia manawa.

Hiki paha iā Canon ke hoʻolauna i kahi kāmela DSLR me kahi kiʻi kiʻi 75-megapixel i ka hopena o ka makahiki 2013. e like me nā hōʻike mai ka hoʻomaka o kēia makahiki.

Ua ho'ākāka kahi patent kiʻi kiʻi Canon hou i kahi ʻenehana like me Foveon X3, e hoʻohana nei i nā papa like ʻole no kēlā me kēia kala RGB. ʻIke ʻia e hōʻike ana ka pahupaʻi DSLR 75-megapixel hou i kekahi o kēia mau mea ʻike.

Ua kiʻi ʻia ka ʻike i kulu ʻia i ka ʻoiaʻiʻo e hele ka mea hana EOS ma mua o kēia nui a e ʻike paha kāna mau mea pā i ka hoʻolaha ʻana o he pahu paʻi DSLR Canon 75-megapixel ma 2013, ka mea e hoʻokuʻu ʻia i ka hoʻomaka o 2014.

Ua hoʻokuʻu ʻia nā hōʻike hou aʻe e pili ana i ka hāmeʻa a me kāna mea ʻike kiʻi, me he kumu hilinaʻi ke koi nei e hoʻokumu ʻia ke kāmela i ke kiʻiona multilayer non-Bayer me kahi "photosite hiki ke hoʻohana ʻia".

ʻO Bayer multilayer sensor vs Sigma Foveon X3

Hoʻokumu ʻia nā kānana Bayer ma ka maka aha i piha i ka photosensors ʻulaʻula, ʻōmaʻomaʻo. He ʻōmaʻomaʻo ka hapalua o lākou, ʻoiai e mālama ʻia ka hapahā i kēlā me kēia ʻulaʻula a me ka uliuli. ʻO ia ka ʻano maʻamau o nā kiʻina kiʻi a hoʻohana ʻia ia i nā hāmeʻa kiʻi he nui.

I kēia mau lā, ua hana ʻo Sigma i nā pōʻai me kahi mana hou i kapa ʻia ʻo Foveon X3. Hoʻokumu ʻia ia i ʻekolu mau papa photodiode, he kuleana ʻokoʻa kēlā me kēia o lākou.

Nā kiʻi paʻi kiʻi ʻo Sigma DP Merrill hopu i nā kiʻi ma 46 megapixels a ʻike ʻia lākou no ke koi ʻole ʻana i nā kānana anti-aliasing, no ka mea he kaʻawale nā ​​kāʻei kala, no laila ʻaʻole e hana ʻia nā moiré.

ʻO ka patent Canon hou e kākoʻo nei i nā lono

ʻO ka ʻike e pili ana i ka Canon 75-megapixel DSLR pahupaʻi ʻole e hoʻohana nei i kahi sensor multilayer Bayer e hāʻule i ka laina me nā kikoʻī hou e hōʻike ana ua kālele ka ʻoihana i kahi sensor like Foveon.

Ua waiho ʻia ka palapala Sila i ka ʻOkakopa 2011 a ua ʻae ʻia i ka hopena o Mei 2013. Hiki i ka sensor kiʻi like Foveon e Canon ke omo i ka mālamalama hou aʻe a me kahi ala ʻoi aku ka maikaʻi ma mua o nā sensor maʻamau.

E like me ka ʻenehana ʻo Sigma, e maʻalahi ka module Canon i ke kukui ʻulaʻula a hiki iā ia ke hoʻopuka i kahi hoʻonā kiʻi nani. I kēia manawa, hūnā ka mea pana "EOS 1D" hou, no laila mai pīhoihoi i ka lono a me ka wānana.
