3-Chipper - How do you get that really sharp picture?
Frage von Martin: März 2007
Sorry for the dummy question - but I imagine a long time, and because of the news article here in the forum.
My knowledge is that the 3-Chipper on "a prism" which makes color separation. Now I have learned a lesson in physics that a prism the light differently depending on the wavelength strongly bends - then yes it will achieve the color separation. Only: Nature is doing us no favors, the three primary colors in each wavelength to provide an accurate, but there is the rainbow continuum between 400 and 800nm. If you now wish to Color Filtering, you will hardly reach exactly one wavelength filter, but it will be a wavelength filter. This area is in the prism vary flexed.
So, the question is: How is the picture still sharp, although the sensor - to varying degrees stooped - mixture of wavelengths true? If the prism in 3-Chipper not a prism, but a complex construction, according to the different color separation diffraction exactly reversed back over it?

Well, not quite. There is talk of mirrors - which I understand, because the incident energy is simply gedrittelt. But then where is the advantage gegemüber the Einchipper?
Advantage of the 3-chip solution but should be that as the sensor for red light at all the "red" wavelength abbekommt, and not just third.
At the moment I simply times so that a 3-chip solution with Prisma colors auftrennt prisms and 3 more divergent color reunited.

With the dichroic mirror, for example the proportion of red light on the sensor for red light. Here, the individual elements can now accommodate larger and larger area than its more light field. The other wavelengths pass through the mirror and get on to them, CCD chips.
At 1 - CCD cameras is not with mirrors, the wavelengths of light to split, but with filters worked. Here are the individual photosensitive elements are often smaller, on the other hand reject the filter to the selected area of each (to be collected) Color in all other incident light contained wavelengths. The filtered units can draw no other light-sensitive element to be.

Hey,
So if you imagine a single pixel and color give this space, it is initially only one point! Now, if more pixel colors assigned to each side will, we should perhaps Picture. But my question: Why should the Camera Picture can not spicy, so if only "one pixel" after another (and not an entire picture) is assigned to? (I did with the prism as in physics and still have not learned physics Leistungskurs ;-))
Many greetings, Constantin

The advantage is the higher resolution. For each base color is the full chip resolution available at Einchipper each color stands for only 1 / 3 of Resolutionzur available.

Anders rum is a shoe out of the sensor pixels are monochrome, so respond to light / dark, not colors, colors are separated before.
Now let's put a prism in front of a sensor and provide us with a white light beam, which was usually without prism, exactly one pixel would take. The prism separates the light beam but in its color on, and it arises as a line image, the duties of a rainbow. The sensor is cordially no preference, it is the line which, regardless of the colors.

Antwort von digitalCat:
I can only schema of the drawing in the Panasonic brochure out, and there goes the light by either straightforward or rear glass is s.der (analogous to the pentaprism in most SLRs) laterally to the two additional sensors rausgeführt. The color separation does by no means cutting through a prism (in all the rainbow colors), insofar as the term is misleading, but probably by filtering each of the 3 sensors fed equal beams.

Antwort von Markus:
It should not be of a simple prism "expect, as in physics teaching is demonstrated. The 3CCD camcorder assembled prisms have interfaces with very specific properties that are permeable to certain wavelengths or totalreflektierend effect. In this way a separation achieved.
