Frage von aight8:
The SonyHDR AX 2000, 1.037 million pixels in the sensor. Full HD pixel corresponds to 2073600. The Picture will be increased by twice the number that is pixel by pixel shifting method. Should not that give enormous loss resolution?
In the Slashcam tests is "very good" and by my subjective impression of a frame I had not synonymous suggest that half of the luminance pixels are simply calculated?
By the way: For what reason are used in a semi-professional HD Cam vollauflösendem this method instead of a sensor?
Antwort von Jott:
Well, I wonder why. Money? Technical problems that occur when Manzu forcing many pixels on a tiny area? Marketing? Demarcation of the upper class? Search's your pick.
Fact is: does not read to you, you know it and not realize you can not synonymous. Pixel Shifting you find synonymous in highly acclaimed JVC and Panasonic cameras of three sensors in full resolution à la EX1 are the exception, at least in the four-figure price range.
Antwort von deti:
You have to qualify this statement somewhat, because the camera has three sensors so and so gets 3.1 MPixel raw data from which they calculated a 2.1 mega pixel high-definition picture. Many other cameras with only one sensor has only 2.1 mega pixel for all colors, so 0.7 megapixels per color and are still in a very good image values.

Okei the good Picture Result actually already explained.
But in general it may be like the moire artifacts emanate always occur when pixel shifting is used, right?
Antwort von Jörg:
But in general it may be like the moire artifacts emanate always occur when pixel shifting is used, right? no, Moire example, there is the Pana151/171 not because they have CCD sensors, although there, the pixels are layered.
Moire is often a child (c) mos chips.
Antwort von Replay:
Moire is often a child (c) mos chips. What? Neee, Objection, your honor ^ ^
The moiré effect is always reached when, simply put, the pixel grid does not match the motif pattern. A typical example is tiled roofs, which are filmed with DSLRs. It is immaterial whether the DSLR has a CCD or CMOS.
