It should perhaps mention that Canon makes no skipping, but binning. Unlike the achieved sensitivity in the movie mode would probably not be explained.

Antwort von Blackeagle123:

Where did you get this information? If the brightness of the high ISO setting?

Quote: bin is often assumed that Canon to pixel binning (= group) uses. In the charge of several pixels is combined into one. However, this would cause problems when Demosaiking (development of the Picture raw data), because each pixel is an RGB color filter (keyword "Bayer Pattern") upstream of the binning would no longer be differentiated.

Neither Canon utilizes a reduced sensor area for the smaller sizes, as this would be different Picture effects (eg higher depth of field) will result. Canon makes uW Although no concrete statement, most likely the small sizes but are simply created by camera-calculations (in interpolation).


The question, of course, what exactly is this interpolation?

If one were to introduce such a Crop mode is able to integrate in this mode, a relatively simple, digital image stabilization.

So why not introduce really like a 4k mode?

And if we are on the wishes are:
Most Lenses have even one of the controllable camera auto-focus motor (either ultrasound or a conventional engine) - for pulling it's Focus on the market but only solutions that replace the mechanical on the focus ring of the lens. Elegant would be a solution, the Poti docks via data cable and the appropriate commands s.die Camera and Lens s.das pass itself. So, without mechanical parts.

Nikon built the engines into the camera, I am so very, very happy! At Canon, the engines are in Lens, but: Have there been problems with the mechanics for Camera?


Quote: The 550D has something like this but something similar, not only FullHD
What is the name of this mode? Is new to me now ... In theory yes, then you'd have to use other Lenses when you power on this mode.

One question I have though: This "Roling Shutter" can 9doch arise only if it is not always the same in each case the third Line recording, but once

Lines 1, 4, 7 ,....
then lines: 2,5,8
then lines: 3,6,9
then back of the front ...

Or am I wrong here?

The fact that Alias | Wavefront Mayaing artifacts arise is logical that would be reduced by a binning ...

Antwort von BLNeos:

This is implemented according Cropmodus canonrumors in the 60D.

According to CR then gives the 1080p mode, with only 50% of the sensor surface is used and will use the 720p mode in which then an even smaller area (28% of the sensor size). -Itself a potent Supersacheinsofern you have enough lenses. Wide angle shots are cracking but not really quite possible.

For each Page belongs, of course, that you then can shoot in 720p mode with a 200mm and a 700mm lens would have the image.

Of course it remains to be seen how the match is. The information will be evaluated on a www.canonrumors.com with CR1.

Which of course only true in theory, because the imaging performance of Lenses is the pixel size by no longer good enough, which can generally result in a muddy picture (synonymous with smaller focal lengths or smaller aperture).

In addition, the Alias | Wavefront Mayaing-effects, especially in wide-angle situations noticeable particularly disturbing. Such recording may simply not occur in crop mode.

For me, the full scale of the input data is the only reasonable alternative. Humanity has already solved problems more severe than this.

There is no real presumption because Tim Smith (Canon) has confirmed this during a speech before the Digital Cinema Society explicitly. (Link here once I had posted a bit ago)
Moreover, the idea expressed above one pixel Binnings (in this factual context) is wrong. Dezeit there are approx. 30 Binningmethoden, of which only one three common (Appendix) are listed. During the Binnings no demosaicing is carried out, but averaged only from the pixel.
In addition, as Deti has already stated, such a sensitivity to light (and as the accompanying signal to noise ratio) only Binning, but not from skipping or windowing can be achieved. Up to 7:1 is achieved here.
The given explanation is very nice to look at and generally synonymous interesting take, but unfortunately DSRL (Canon) does not.
It uses the knowledge of blogs that is sometimes the only one who believes not everything.

I do not know if I have the now well understood, but the RS is created so by the
Reset of all pixels of a line, the
Integrate all image points of a line, and the
Readout of all pixels of a line.
Only with the completion of the integration phase is the content of the image point of the fixed image.
Note that with the end of the integration phase of the line 1, the integration phase of Line 8 begins.
If one were now skip lines, the RS would arise as a rough zigzag pattern. We had a very fine already in the interlace method. A must now imagine much coarser.
Rolling Shutter is to be avoided in the first place by parallel readout of the chip or by increasing the selection bar.

But nothing Binning is really ... it only happens at a very early position to limit the (otherwise) immense data flow at approx. 6,5 Gbit / s would. Even the K7 has increased to four data channels in order to (achieve only) 5.2 frames / sec. And so it is with 1.5 Gbit / s just before the melting.
Since binning is already attached to the method.

Time, quite apart from the above blog content includes synonymous in terms of windowing a very decisive Gedankenfahler.
To create a 1920x1080 HD Resolutionzu I come with such a window, of course not, because he confused because pixels with pixels.
For such a 2 million "Full HD Resolutionbenötige I but (at least) six million pixels (each 2 million red / green / blue).
I would only open a window on the sensor of 1920x1080 "" I would be a "better" WEB-Resolution.

Well the question is, how it is implemented. Canon obviously loses information so that it comes to Alias | Wavefront Mayaing.
Would be a weighted sum would be used, the problem is not more likely to be perceived.

Antwort von WoWu:

I understand your approach .... only one such "Vollauslesung .... 24/25/30 and the times / sec (or at some times 50 times / sec) is not feasible.
But you are absolutely right that Canon in binning not function well.
Although I think this is already binning for the best compromise, especially as the amount of efficiency can thereby increase considerably, probably one of the strengths of these cameras.
Sure, Alias | Wavefront Mayaingproblem (or something that looks so) to buy a so ...
For me, the best solution would be a "reversible" optical filter that performs an optical lens to match the reduction.
Illusory .... I know, but probably a solution to the maximum detail to achieve.
Although I am not of the opinion that it is all Alias | Wavefront Mayaing. Rather, I think it is a matter of Abtastpattern, because through awkward binning is not achieved by 1 / 4 of the sensor resolution, but sometimes only 1 / 16 or less.
(Check out the views of the Green Pattern Binnings to. A "normal" Binning, works on the apparently synonymous Canon, covers too little Resolutionab. (Annex)
Another binning would then remedy the situation. (2) would be such an example, the effects that look like Alias | Wavefront Mayaing, are in reality but one Binningeffekt, would avoid.
I would therefore once such a picture in relation to Alias | Wavefront Mayaing interested if such effects are already removed.
Perhaps Canon does indeed look in the petty cash and purchase a license at DALSA or Kodak, or may, as always, the rights holder of such Binningmethoden hot synonymous.
The "air" in terms of improvements is certainly far from out.

Antwort von Gabriel_Natas:

Aliaising formed yet, because the dissolving Optics higher than the sensor.
By Pixelbinning is artificially reduced, the sensor resolution.

Therefore there is a difference between Pixelbinning and downscaling of later.

The whole problem could be resolved ALiaising relatively straightforward when screwed onto a filter lens, which is designed for full HD and not for 18 megapixels:).

Videocams have a corresponding LowPass filter installed in front of the sensor.

The filter of the 550D is designed precisely to 18 megapixels and not on second



The Alias | Wavefront Mayaing at VDSLRs arises because at 9 BIld Pixelbinning then put the points take care of one.
But that means synonymous, because the whole a camera that can penetrate through the Optics and the low pass filter up to 9 different light stimuli (when the to film the object is sufficiently detailed), take on these 9zu1 pixel on the chip. This leads to Aliaising. Even if the aufgetretetenen light stimuli are averaged.


A corresponding low pass filter would ensure that these stimuli would be a 9 light (make blurred). This optical solution would be to prefer arise because so no aliasing can.

Antwort von WoWu:

Jau, Gabriel, that's exactly what I meant. However, I do not really think that your camcorder will have a filter, because most already Lenses act as low pass and such OLPF were actually made for monitors and have to sit at least 1 mm of the surface removed to be effective. Difficult for sensors feasible. Furthermore, the reflective surfaces of these Sandwichkonstuktionen so vague that it would probably a funny picture out .... so I said "illusory".
But as I said, a big part of what disturbs is not at all times, Alias | Wavefront Mayaing.
Canon would come with a different binning one step next. Quote: 18 megapixels and designed not to 2

For me, a true three RGB pixels pixels: D
The RGB pixel count, where you determine the actual Resolutionimmer should base that is expected by 3, I find stupid: =).

That's right, do not need a fixed lens camcorder with low pass filter, because one can perfectly to the Camera and Lens custom build the chip. On cameras with interchangeable lenses you would need such a low pass filter, unless it is confined to a few predetermined Lenses.

The cheapest method to make as the 550D or other video DSLRs Alias | Wavefront Mayaing-artefact would be a blur filter is screwed onto the lens.

In the United States is, for example Caprockfilter which have achieved very good results.

Does not quite synonymous. The green pixels in the Bayer pattern twice as often present as the red and blue. Thus, the applicable factor depends on the debayering algorithm.

No, the cheapest way is not fine structures filming.

That is what I like the RGB Pixelzählerei not. It says nothing about the actual resolution performance.

Antwort von WoWu:

Well yes, but I can not reciprocating in no case and, as in the above-advertised blog, just say, I just want to 1920x1080 and taste ... ergo .. only every third row.
I think you really have to distinguish between image resolution, so details and pixels of a sensor.
So much detail has to be even at all, Alias | Wavefront Mayaing.

Quote: That's right, do not need a fixed lens camcorder with low pass filter, because one can perfectly to the Camera and Lens custom build the chip.
-Can-that's the magic word ... But if one does not, because it would be the built-in chips knopfgroßen lenses all the greater.
Or, conversely, the Lenses were all in the tiny sensors, at least as good as the Zeiss Referenzobjektive (and better).
Unfortunately, the gap yawns as well apart in the opposite direction.
Since the Misen images are generated by the "low pass" Lens.
The question remains, what is better. Blurred images due to small sensors and lousy Lenses or blurred images due to large sensors and to good Lenses ...
Man, man, this is perhaps a crazy technology.

It seems to me that it can only go so, as it dominates JVC right now, what the competition does not create easily. The new Canon camcorder not come back so promptly s.die Resolutionder up HM1.
Actually, now missing only the magnification of the sensor on 4 / 3 "with larger pixels, and the matter would be resolved both of the Stillimage as synonymous of the video side.

Antwort von WoWu:

Where on the video page then urgent nor the 50% data (forcibly) reduction of interlaced mode must disappear .... but the evidence again points to a too narrow processing of the sensor.
For the Up-Converting s.Output of i to p's can not even be synonymous. And if the camera similarly strong filter cartridges as the 400 and he has revamped with razor-sharp edge sharpening their values, then that is for me synonymous not just in the category of good cameras.
Perhaps that is synonymous only to the storage media eingschränkten owed.
I would be interested to know how a picture looks like the HDMI output (if available). Only then you could really say whether the work of the lens / sensor combination.
But, I geb'Dir right half is still borderline with such tiny lenses and any increase would s.Chipmaßen counter.

:-)) Why deliver Fujinon (Zeiss and as they are called), not long Lenses with its sensor and a small picture-DSP s.einem HDSDI output.
Then everyone could dock the codec and Recorder's his choice and is good. Then would rather solve many problems.
