  1. Re:Reverse DLP on CNet Tracks the History of the Digital Camera · · Score: 1

    Imagine a beowolf clus I mean array of them. I'm still working it out. I was thinking maybe you could use an ANALOG sensor on the far end (the 4 pixels part) and then use a high range A/D converter to digitize the resulting waveform. Then I was thinking, maybe you could make one that the mirrors could scan in 3 different directions instead of just on-off, and have MORE sensors there. I don't know, I'm not really a scientist. They do have a switching speed of 15us which is quite a bit faster than typical exposure times. I'm sure someone will figure it out. It makes sense that if the benefits are there for projection, the same benefits should be there for recording. QED.

  2. Re:Reverse DLP on CNet Tracks the History of the Digital Camera · · Score: 1

    I'm talking about focusing the light on one large sensor. If it can easily scan 30fps at 1080 you're looking at a 1/30s exposure, which isn't too bad. Furthermore, the mirrors actually flip hundreds of times faster to make the greyscales during projection. I admit this sounds disingenious but if you have multiple sensors for each color you could easily multiply the number of actual real world "pixels" or resolution seen by the camera without having more pixels on the sensor. Obviously they aren't the best for scanning because they really have more of an array effect. But, just as in the projector, you would have a "light dump" which would absorb light coming from angles that aren't currently being scanned. Look at the switching speeds for the Texas Instruments DMD's, on the order of 15us, or 1.5/100000s, definitely above what is standardly used. If you were to bring it down to 1/1000s, you could easily scan through 150x the pixels with the same sensor (you'd need an array so you're not subject to the lag time inherent in all CMOS and CCD devices.)

    My cell phone camera will create a squished picture out the car window at 30mph, and I know this is CPU based, not sensor based. Likewise, I think the DLP camera would have no problems switching fast enough for even extreme shutter speeds, but you'd need a wide bus to capture the data. You could have a very large sensor surface which means you can lower the gain and have a greater dynamic range. CMOS sensors, even in the experimental arena, are barely able to reach 100db even utilizing double sampling techniques (a form of interpolation). The human eye, by contrast, has 200db range. I think with a larger sensor surface 175-180db could be easily acheivable, especially with some type of active cooling (maybe not cheap enough for a handheld). Perhaps a return to an analog sensor with a wide range A/D converter could get you to 180db.. I can think of many other uses, such as telescopy, etc. where having a high dynamic range would be worthwhile, especially on non-visible wavelengths.

  3. Reverse DLP on CNet Tracks the History of the Digital Camera · · Score: 3, Interesting

    What about the future of the digital camera? The CCD is reaching the end of it's useable life. They are just packing more and more pixels in, when really what you need is more levels of greyscale and a better signal to noise ratio. I'm wondering when they'll get rid of CCD entirely and move to a 4 "pixel" sensor with a DLP chip in between handling the scanning, instead of a bunch of piddly pixels on a 1/3" ccd. The sensors could be larger, with focusing lenses in between. The color isolation would be perfect. Plus you could use variable filtering/exposure PER COLOR based on the ambient light to do true (not digital enhancement after capture) white balancing. There's no reason a DLP couldn't work in reverse, I don't think. Other possibilities include nanotubes "tuned" to certain visible frequencies that cause them to vibrate slightly, etc.

    There's also the liquid lenses such as Varioptic, which are going to change what we know about photography. Coupled with GIS/GPS I think we're in for a great next century.

If you've ever had to fill the same damn personal history form out again and again, you know why this might be useful. Also, you can edit it to show whatever you want. It's getting to the point where we are going to have to take care of ourselves. There are simply not enough doctors. Use this to keep yourself healthy, move all of your insurance to high deductible plans, fund a Medical Savings Account or HSA and start taking back your medical options.

    Maybe the Russians and Chinese are the greatest threat to the Free World and not some deluded Muslims.

    It's important to make a distinction in your mind that People != Bad Leadership. I think the majority of humans want the same things out of life. It's just that the power-hungry float to the top...because they WANT it. So, you tend to have power-hungry, seven-deadly-sin embracing douchebags at the top and regular folks like us at the bottom. The problem with Russia and China is not their people, but the fact that their leadership has little or no checks and balances and so the power-hungry douchebags at the top can do evil with no consequences. It has been like that here in America lately, since everyone was so paralyzed in "fear" of "terror" (that sounds funny, doesn't it?) that we let the government (which was also free of the normal R vs. D dichotomy) and especially the Executive branch have it's way. And what happens? The power-hungry snatch more power at the expense of the people.

    Now, back to your comment. The Russian leaders and the Chinese leaders have shown a willingness to play in the global economy. They've also shown a willingness to direct their people in a decent way. They have embraced capitalism, even if they are trying to back out constantly, I don't think they can go back. As generations pass, the "old" leadership in Russia and China will gradually be replaced by the "new", and just like in America they progress, slowly, toward a more perfect union with a free-market economy.

    In the world stage no one can really CONTROL the world economy. You can only set the trends. And as America is the biggest, and American companies in that economy are the world's biggest, we set the economic trends that the rest of the world follow. The problem is we are not being wise with our spending, and we're borrowing a lot of money as a country and it's going to be a long time before we can make that up. That's what we get for letting power-hungry people print their own money and increase their own power.

    You are correct, however, that under the right (wrong) leadership, China and Russia represent the greatest threat to the American idea of the "Free World" (ie: free market), simply because they muster so many people under them, along with massive resources and land assets. Islam is merely a religion, not unlike Catholic or Hindu. Bush, an evangelical Christian, would like you to believe that the Muslims represent some sort of apocalyptic society (because that's what he believes), but in reality, the almost 1.8 Billion muslims are as a majority good people. I don't care if they don't believe in Jesus.

    Now, in the middle east, Muslims have been used as tools by the Anglo Saxons since Christianity began. Naturally the rise of Radical Imams and the like occurs during times of great poverty and this is one of those times. During the 60's and 70's the exponential rise of oil fortunes in the middle east has resulted in, you guessed it, power-hungry people getting lots of money and power and using it to keep down their people. If we are so concerned about "democracy" in Iraq, why don't we get the Saudi MONARCHY to let it's people go democratic? Or Jordan. Because you see, radical islam is bred in spots where there are leaders like this who keep their people down. It's the people's way of fighting back. The fact that they've turned their attention to the suppliers of power over there (America) is only natural. We supply the money, weapons and other gear to the Israelis, Saudis, Jordanians, and more that they use to keep the poor people down. It's no wonder they don't like us very much.

    But no, they are not a "threat" per se, since Radical Islam only flourishes with poverty, lack of education and of course a power-hungry person at the top to keep the poor down. There are MANY Muslims in America and you would never know them becuase they are no different than Christians, other than they don't believe in the Jesus myth, they believe in the Mohammed myth.

    Anyway, I'm not scared of China and Russia either, but I do agree that Burma is a hotbed and could produce terrorists also, because they are being kept down and not allowed to be free.
