It is a special camera used to photograph Unobtanium.

Or, maybe this: 1-Pixel Camera

You mean 1M pixel (one mega-pixel), it is an old digital camera in which sensor, each picture unit or pixel is composed of three dots: Red, Green and Blue.

A one-pixel camera is, in a way, the optical inverse of a digital projector. A digital projector uses a point light source projected through an addressable array (like an AMLCD or a digital mirror device) to create an image.

Conversely, a 1-pixel camera uses a single pixel to capture an image, but the light gets to that pixel through an addressable array. Here is a link to the Bell Labs version:

I agree with Yahlisit that somebody most likely made a typographic error by dropping a letter here and this is likely a 1M-pixel or even a 1K-pixel colour camera.

Now if your question is accurate it would help to know how this sentence fragment of a phrase is used in a sentence. This could be a description of a single element photo-sensor with either a color filter or diffraction grating configuration to isolate only one color of light permitted to reach the photo-sensor. This kind of a configuration is used in various types of absorption and reflection spectroscopy.

As i understood it, it is a one pixel color camera mark sensor. The supplier description for it is as follows:

The adaptive register mark sensor of the is able to detect extremely low-contrast colours and metalized inks, as well as transparent lacquer. The register mark sensor developed as a 1-pixel camera analyses the colour spectrum of the light reflected from the web, and automatically detects all types of register marks. Thanks to the great depth of focus provided by the fiber optics, the user must change neither the signal amplification nor the scanning angle - the reliable mark detection is performed without any operator intervention. As a light source a long-life maintenance free LED is used. For the first time, it is possible to provide the operator with a live colour image of the register marks due to the newly developed 1-pixel colour camera.

How did the phone call seeking clarification with the supplier's technical helpline go?

If you are that into forensic analysis, you should really know what you are buying without asking for help here.

If you are willing to provide the catalog information, why not provide the full product information?

Basically, there is one photo receptor site and a matrix of very small mirrors used to sequentially scan an optical image in a raster-scan fashion.

The micro-mirrors/sensor creates an image by randomly flipping the micro-mirror array mirrors into one of two position (on & off) and the photodiode recodes the data for each flip.

A mathematical algorithm reconstructs the data into an image..

There are probably other topologies in use, but the concept is the same - one photosensor is used to capture an image.

I am not sure how they implement color. Either they use some form of filter (mechanical or digital) to segregate the different wavelength of light or they would use a cluster of three photo sites that are specifically sensitive to the reg, green, and blue wavelengths.

A typical consumer camera uses an array of pixel photosensors in either a Bayer matrix or a Foveon matrix as a rectangular sensor. Essentially, the there primary colors are recorded by a cluster of RGB sensitive pixels. Lenses are used to focus an image on that sensor block and the image is digitized in a single event (all sensor pixel data are dumped to a form of RAM, then streamed out to a processor in the camera.

This is different that the single pixel camera, which must sequentially gather data in a random scan fashion from a single sensor.

I am not sure of all of the advantages, but one advantage that comes to mind is that you eliminate the variation you would normally have between multiple sensor sites and the image would yield a higher degree of color or light intensity fidelity.

please check the website for this 1-pixel camera sensor: http://www.eltromat.de/en/products/register/

the supplier does not provide this sensor datasheet...

If it exists, it is something you don't want to buy, unless you are involved with microscopy (my guess).
