FOVEON: There is no substitute

Why The X3 is Way Betterer

To capture the color that other image sensors miss, Foveon X3® direct
image sensors use three layers of pixels embedded in silicon. The
layers are positioned to take advantage of the fact that silicon
absorbs different wavelengths of light to different depths. The bottom
layer records red, the middle layer records green, and the top layer
records blue. Each stack of pixels directly records all of the light at
each point in the image.

Until now, all other image sensors have featured just one layer of
pixels, capturing just one color per point the image. To capture color,
the pixel sensors in CCD and CMOS image sensors are organized in a
grid, or mosaic, resembling a three-color checkerboard. Each pixel is
covered with a filter and records just one color-red, green, or blue.

That approach has inherent drawbacks, no matter how many pixels a
mosaic-based image sensor might contain. Since mosaic-based image
sensors capture only one-third of the color, complex processing is
required to interpolate the color they miss. Interpolation leads to
color artifacts and a loss of image detail. Blur filters must then be
used to reduce color artifacts. The use of blur filters adversely
affects sharpness and resolution of the final image captured.

With its revolutionary process for capturing light, Foveon X3
technology never needs to compromise on quality, so you get sharper
pictures, truer colors, and fewer artifacts. And cameras equipped with
Foveon X3 technology do not have to rely on processing power to fill in
missing colors, reducing hardware requirements, simplifying designs and
minimizing lag time between one shot and the next.

Dollar for dollar, pixel for pixel, nothing compares to Foveon X3
technology.

A very poor attempt at trolling...

The OP is merely a cut and paste from this site:

Why it haven't been popular if it is so good?

He sends copies of this crap back to himself, so he's not lonely.

Inarticulate, yes.

Kook groups removed.

Ah, because this is a troll, groups adjusted.

Just one question. If it is so superior, why doesn't the entire
industry adopt it?

Actually every camera manufacturer is now using the technology but are far
too embarrassed to tell us!

In complete agreement that the OP is in need of professional help, or
at the very least a new prescription on his meds.

What does "groups adjusted" and similar terms mean?
