My mind the ideal digital camera.

- Who can do one out? .I kowtow to offer huge sums of money for! .First, apologize to you, reading takes a lot of imagination. .The first is the lack of diagram (I use CorelDraw draw some, the effect is bad, only decent use 3DMax), Furthermore, I said something a little like science fiction - in fact not always the case, I bet this thing is a big .Plant Design Studio <! - content start -> <hr size="1"> <p align = "center" style = "line-height: 120%; margin-top: 0; margin-bottom: 0" .> <P align=center> - one who can do it? .I kowtow to offer huge sums of money for! .</ P> <P style="MARGIN-TOP: 5px; MARGIN-BOTTOM: 5px; TEXT-INDENT: 30px; LINE-HEIGHT: 120%" align=left> first apologize to you, will need a lot of reading .imagination. .The first is the lack of diagram (I use CorelDraw draw some, the effect is bad, only decent use 3DMax), Furthermore, I said something a little like science fiction - in fact not always the case, I bet this thing is a big .room to discuss the plant design, maybe the internal R & D project applications has passed, and now with the CXO Product Manager in their discretion, "If the market demand sufficient to support the development of such a camera, and so the production 。。。。。。" .. .This article is not so much fantasy as it is prophecy. .I desire so strong, so solemnly invited fans of you to help me share some of the equipment. .</ P> <P style="MARGIN-TOP: 5px; MARGIN-BOTTOM: 5px; TEXT-INDENT: 30px; LINE-HEIGHT: 120%" align=left> First, sensors </ P> <P style = ."MARGIN-TOP: 5px; MARGIN-BOTTOM: 5px; TEXT-INDENT: 30px; LINE-HEIGHT: 120%" align = left> that digital camera, of course, talking about the heart from it. .CCD and CMOS on nothing much I want to argue it, work on the digital camera on battery, the power is always a very important indicator. .Power consumption, heat is also small, the thermal noise level is much lower. .Canon has come out of a successful first step. .Well, our Dream DC on the selection of CMOS it! .But this enough? .No! .There is also a significant "digital advantage" No use, it is shape. .Traditional film and film can not change the aspect ratio, but the silicon can be. .I imagine that an octagonal photosensitive device: first draw a circle with a diameter of 43.2mm, and then into the aspect ratio of 3:2 and 2:3 of the two internal rectangles, cut them short side of the arc .throw away, in the remaining four paragraphs to do outside the arc tangent 45 °, extension, and anyway in both the short side of the rectangle to extend lines intersect. .Well, this is what I want to shape. .What good is it? .First, it has a "back spin" effect, making not turned the camera vertically, switching a lever on the line. .Furthermore, the format is indeed affected the composition aspect ratio, using both 135 and 6x6 DX two systems must fully understood, the use of large machinery DDX 4:5 may insist that we go by. .Well now, you can adjust from the banners had been 3:2 to 2:3 vertical banner! .What 135,645,6 x6, 6x7, 6x8, 4x5 all clean sweep, word of no longer difficult to tune. .Various aspect ratio imaging camera able to take full advantage of round, no waste. .Yes, 612 and 617 it? .It does not matter, we can use digital software to access films, used large-format aspect ratio lens is also a serious waste of resources. .This octagonal-shaped light-sensitive area of the device more than the traditional 40% to about 3:2, of course, cost will rise, but I think the benefits are worth it. .Oh! .By the way, was to use the lens hood round </ P> <P style = "MARGIN-TOP: 5px; MARGIN-BOTTOM: 5px; TEXT-INDENT: 30px; LINE-HEIGHT: 120%" align = left .> and then talk about how many light-sensitive pixel devices is enough. .Enough to worry about this problem, and here I strongly recommend you read the http://www.smu.edu/ ~ rmonagha / mf / limits.html. .Which has a conclusion that 50lp/mm (line pairs / mm) is basically the limit of traditional film systems, as well as one of a summarized table out: </ P> <P style = "MARGIN-TOP: 5px .; MARGIN-BOTTOM: 5px; TEXT-INDENT: 30px; LINE-HEIGHT: 120% "align = left> - do not pay attention to the use of the system under the 135: 600 million pixels </ P> <P style =" MARGIN-TOP .: 5px; MARGIN-BOTTOM: 5px; TEXT-INDENT: 30px; LINE-HEIGHT: 120% "align = left> - be used with caution Kodakchrome: 1200 million pixels </ P> <P style =" MARGIN-TOP: 5px; MARGIN .-BOTTOM: 5px; TEXT-INDENT: 30px; LINE-HEIGHT: 120% "align = left> - extremely careful to use Velvia: 2200 million pixels </ P> <P style =" MARGIN-TOP: 5px; MARGIN-BOTTOM .: 5px; TEXT-INDENT: 30px; LINE-HEIGHT: 120% "align = left> - extremely careful to use Agfa Tech Pan: 3500 million pixels.
