Infoseite // Does the EX1R with Pixel Shift?



Frage von mschuelbe:


The title says everything ... Despite a long search, I could not find anything about this, and one webcam with pixel shift I want to get me anything in the house. Thank you in advance for the info!

No. Of course not. The EX-series works with 3 each full-frame sensor (1920x1080).

Danach hat zwar None gefragt, aber der Vollständigkeit halber sei erwähnt, dass die EX1/3 with einem 1/2" Sensor arbeiten. Der Sensor ist vom Typ IMX015 with 2024×1485 also im 4:3 Format, davon werden immer 1920x1080 ausgelesen. Quelle: SonyService-Manual

Interlace:
"Vertically, there is a gradual extinction starting s.about 540 and clean and completely extinguishing s.about 1000 lines / picture height."

Progressive:
"... There is now the same depth of modulation s.1080 vertically s.there is s.1920 vertically."

vs.

http://www.bbc.co.uk/rd/pubs/whp/whp-pdf-files/WHP034_ADD25- Canon XHG1.pdf

XH-G1/A1 via HD-SDI:

"There is vertical resolution up to a vanishing point s.about 1015 lines albeit s.low amplitude, above which there is a good freedom from aliasing. Horizontally, strong resolution is up to about 1600 pixels."
...
"Fig.4 shows the result for setting the camera to 25p, again captured via the HDSDI output. Very surprisingly, the vertical resolution is a little lower, reaching a vanishing point s.about 940 lines / picture height."

Conclusion: EX1 / 3 increases in a progressive mode 1920x1080 HQ in interlace only about 1000 lines. The XH-G1/A1 comes in at 1600x1015 interlaced, progressive, but only about 940 lines.

That is so synonymous in the review: The Exen the Picture is progressively sharper than interlaced. Yes somehow synonymous is clearly ... - (In return it provides for all his Canon cameras progressive mode to make the blur, we had already) in another thread.

We can expect even times, whether by bringing the whole Pixelzählerei what if the lens it can not:

IMX 015 => 2024 x 1485 4:3 = 3.005640
Usable pixels in 16:9 => 2002 x 1126
Sensormaß => 6.4 x 4.8 mm

1920 dots / 6.4 mm = 300 dots / mm = 1 / 300 = 0.003 mm

Spatial frequency required for the Lens =>
1 / (2x0, 003) mm = 1 / 0, 006 mm = 167 lp / mm

When you consider that the only way of Zeiss Referenzobjektive to 160 - 180 lp / mm have, come to light to doubt that the Shard for a few hundred dollars does the same job as a 35,000 EUR Lens.

The Lenses are in bonsai-resolution sensors always the limiting factor, and rather act as a lowpass filter.

Whether your idea is so so wrong ... I do not think.

Nope, Ruessel, the BBC text actually even goes next with the declaration:
Quote: According to the specification, the sensors have
approximately 1,560,000 active pixels, which means that for 1080 --
line there must be 1,560,000 / 1080 = 1444 pixels, probably 1440, the
resolution limit of HDV. Clearly, the camera is delivering greater
resolution than the pixel count would indicate possible, this is due to
The "precision-offset" of the green from red and blue sensors.

Pixel shift in this regard is the magic word.

Since you already have as many errors as useful signal. Therefore Resolutions are always given at 45% MTF and 10% below Nyquist.
Here are some figures have been seized and easily understood as a resolution.
If I am an identical error. I like the useful signal, the signal is already no longer use it.

Quote: He was referring to but the Canon:


all right .... but it is often called high-resolution figures I've ever seen on my flat-HD, not synonymous with a looping HD signal. Even in Exen FullHD operation not let me "Wow," said ..... this is still lacking a little bit resolution. For good Bluray but lacks a large number of pixels .....

Should not resolve it not for a true HD picture, the sensors even higher than 1920? Even though 3 of them play in the camera are fitted?

Matsushita has to a patent, but admits that at 1 / 3 "is the lower limit is reached. But that's why the sensors are synonymous relatively large pixels, for 1 / 3 are" no longer synonymous with higher Resolutionwäre there.

For me it was synonymous, but primarily about that (yet again) it was assumed that was attainable Resolutionim space. Ab and then you have to once again ground. Of this we are away for a few.

The 400 has a priority processing => The edge enhancement varies with the complexity of the image.
So watch at times complex image content on the sharpening.

Antwort von deti:

That is terrific: they've since installed one 10.3MPixel Sensor and manage it to produce 2.1 mega pixel with no scaling errors. As daft as it sounds, but to my knowledge, neither creates nor Canon Panasonic correctly (have no idea how) at Sonyist.

What is there to be scaled? The color mask already ensures that the Resolutiongrob is enough for 2k.

There are so good as any DSLR but without the color mask with 3 sensors. So the thing from my amateur perspective can not be serious, especially if enough pixels are available for interpolation. I do not know, the RED One and the Scarlet actually 3 sensors?

Quote: times kick off the test chart, try them out.

Quote: JVC used as 3 x 1 / 3 "sensor with 1280x720 pixel shift, Panasonic 1 / 3" 960x540. The result is muddy pictures of a far right HD resolution. The EX1 / 3 at least slightly s.The 1000 lines go there.

If I had to buy a camera, it would probably be the Ex1R ...

Well, what we call as serious, up to 50% depending on the color mask.
As far as I know, use the Red an RGB stripe pitch, which is slightly better than the Kodak or Sony masks.
Quote: 960x540
There it is again ... CCDs will not be there with high resolutions. The signal is not easy to exploit if it has gone through 3000 pixels and has lost most of its electrons, however, each pixel has collected enough electrons from the previous model and pre-predecessor to the tunnel.

Ahhh ... I understand .... So synonymous with larger-HD CCD sensors do not make sense?

Space


Antwort von WoWu:

Not really, it just goes to the poor signal quality when increasing the number of pixels. Exceptions are (schweineteure) Buried-channel CCDs. For example, of DALSA. (Scale of 800-1700 $ / pcs)
But if even ARRI with its development goes to MOS, which will then CCDs. And MOS or CMOS does not have to necessarily read it as at present (RS). E is always a question whether we donated 2 more transistors (per pixel) or not.
And you have the synonymous global shutter. I think that the chip is still rapidly developing next.

Space


Antwort von domain:

@ Joerg
So it is.
We must not seriously believe that such a superhot but faint Amateur clutter without professional features such as HM400 could be compared only in the smallest way, synonymous with the EX1 / 3. Applies synonymous for Panas, which were for its soft and beautiful images with beautiful gradation has always known.
But the potential severity Resolutionund not count, it must be captured mood and feeling, and good skin tones and numerous controls and and be present .....
