Advertisement Posted November 12, 2014 Posted November 12, 2014 Hi rosuna, Take a look here Sony's Active-Pixel Color Sampling sensor (APCS) will change all.... I'm sure you'll find what you were looking for!
jaapv Posted November 12, 2014 Share #2 Posted November 12, 2014 There is some scepsis out there by experts- something about unlikely voltages. However it might be an idea circumvent the Foveon technology. Lets wait and see Link to post Share on other sites More sharing options...
pop Posted November 12, 2014 Share #3 Posted November 12, 2014 The text mentions moving color filters. Hence, each pixel is exposed three times. This nullifies the claimed advantage of any reduced amount of data which has to be moved and processed. The claim that aliases would not occur any more is exaggerated; it's only the kind of alias introduced by the color separation filters which is eliminated. Lastly, since the colors are exposed in sequence, new kinds of artifacts will arise when parts of the picture move between exposures, not unlike to what we see in colored images assembled from three separate exposures, if not, perhaps, as marked.

farnz Posted November 12, 2014 Share #4 Posted November 12, 2014 If it incorporates moving colour filters then I'd expect reliability to plummet and power drain to rise owing to the moving parts. Also there's a likelihood of noise generated by whatever motive force is used to create the motion of the filters. And if each pixel needs to be exposed 3 times it suggests a speed asymptote for exposure value. Pete. Link to post Share on other sites More sharing options...
rosuna Posted November 12, 2014 Author Share #5 Posted November 12, 2014 It seems to be serious... Sony to launch world's first per pixel color sampling sensor in 2015. | Mirrorless Rumors "moving" maybe means "changing"... Link to post Share on other sites More sharing options...
pop Posted November 12, 2014 Share #6 Posted November 12, 2014 I move that we read "moving" when "moving" is written. They could place a rather traditional Bayer filter on a movable plane and move it to and fro by the length of a pixel using piezoelectric engines or some such.

mirekti Posted November 12, 2014 Share #7 Posted November 12, 2014 Advertisement (gone after registration) All I can say, the future will be bring many more exciting things (as it always did). In the meantime I will enjoy in what I own. Reading articles like this just make me day dreaming too much. Link to post Share on other sites More sharing options...

jaapv Posted November 13, 2014 Share #9 Posted November 13, 2014 No more moiré seems unlikely to me. I'll accept no more colour aliasing, though. If we are talking moving colour filters I fear for the precision. I cannot believe that micro piezo technology has advanced that far. Link to post Share on other sites More sharing options...
fotofool Posted November 13, 2014 Share #10 Posted November 13, 2014 This idea (at least moving the sensor under the array) was patented in 1989 and has been in use for years in various specialized CCD cameras made by Zeiss, Sony, Nikon and others including... Leica DFC550: Leica Microsystems Here is a Jenoptik marketing brochure describing it... http://www.imagingplanet.com/images/datasheet/co-site%20sampling.pdf Although I'm no expert I suspect there are many practical reasons no one has tried to do it in a portable general purpose camera and remain skeptical that Sony will do so.

michaelwj Posted November 13, 2014 Share #11 Posted November 13, 2014 Its interesting for sure. I took 'moving' to be used very liberally. I'd imagine that they could possibly manipulate the band gap very rapidly they could resolve energy. I'd have thought they would try to come up with something like a SDD in use in X-ray spectroscopy, but for visible light - each photon that arrives gets its energy measured on the fly, no multiple exposures. Interesting times! Michael Link to post Share on other sites More sharing options...

saxo Posted November 16, 2014 Share #14 Posted November 16, 2014 More information: . More information? At that stage, I would rather call it more speculation. Indeed, if it proofs to be a feasible technique for large sensors (full frame) it would be a revolution in high end digital photography (and video as well). High sensitivity, high dynamic range, high resolution and spectaculare b/w pictures (no need for b/w sensor anymore), even with stepless software-color filters after(!) the shot. This sounds too good to be true to me, but we will see. Sony the leading company in digital photography, what a change! Martin Link to post Share on other sites More sharing options...
NJH Posted November 16, 2014 Share #15 Posted November 16, 2014 Sony already are the leader due to their pervasive sensor technology. I suspect this sensor first appears in some outlandishly expensive pro video camera. Link to post Share on other sites More sharing options...
