Stanford ready to snap 'super-3D' photos

Original post made on Mar 24, 2008

Stanford scientists are developing a technique to take "super-3D" photos using the equivalent of 12,616 lenses.

Interesting; but, offhand, I'm not sure large depth of field is a worthy outcome, when using very small-sized pixels.

Small-sized pixels often -- at least in high-end, professional 35mm cameras made to date including, but not limited to, those made by Canon and Nikon -- produce significant noise. Such noise requires in-camera processing hardware; and, even with such hardware, many photographers modify the resulting images with substantial software packages.

Noise is a particular problem with high-ISO photos; high-ISO shots are often required when natural light is too low or flash is unavailable.

As an example, Nikon released the D3 last year, a camera lauded for its relatively low-noise at high-ISOs; the pixel size of the D3's sensor is 8.45 microns, or a little over twelve times (12x) the size of the pixels in the sensor described in the article; the area of such D3 sensor pixels are thus roughly a little more than one hundred forty four (144x +) the area of the pixels of the sensor discussed in the article.

The camera noted in the article employs a single lens for every 256 pixels; note, however, that Canon's CMOS sensors in the 1D line (e.g., the 1Ds Mark II and 1D Mark III) have micro-lenses for each and every pixel. The 'micro-lens' employed by Canon in such scheme may not possess the performance abilities of the Stanford proposal; but, the concept of a lens in front of a pixel -- or a group thereof -- on a sensor is not new.

Despite the foregoing, the goals of the camera -- large, perhaps infinite, depth of field using hardware only -- are laudatory; as such, it's an interesting idea, worthy of further research.

When those Stanford 3D photos are transmitted around the globe, fiber optics will most likely do the job.

An article on high definition 3D television appeared in the Guardian last year discribing a 3DTV demonstration by the Paris telecom company Orange to show off their 100 Mbps fiber to the home (FTTH) network they were about to launch in Paris.

The reporter was wow'd by the clarity of the 3D movie he watched without glasses on a plazma flat screen TV. The story URL:

I believe Palo Alto selected a couple of companies to propose how a citywide FTTH network might be built to serve ever business and residence in town. Does anyone know where we are on that? I would love to watch hi def 3DTV on my flat screen.
