*** EDIT: Comparison between Satio and E72@12MP in the end of this page. ***


Today I got curious about the quality of Satio's 5mp photos, then I took some shots and compared it to the 12 mp ones.

Look what I got when I rezided the 5mp ones to 12mp (click on the miniature to see the full photo and then, in imagehack, right-click -> "view photo", to view in 100%):

1- 12MP


1- 5MP (Resized to 12MP)


2- 12MP


2- 5MP (Resized to 12MP)


3- 12MP


3- 5MP (Resized to 12MP)


4- 12MP


4- 5MP (Resized to 12MP)


5- 12MP


5- 5MP (Resized to 12MP)



Ridiculous. 12mp photos are just expanded 5mp ones, there is no additional captured detail. The only difference is the amount of compression added.

This is a great way too sell super mega high megapixel flagship phones! What a shame.

So you finally discovered the megapixel myth?

The Satio does have a 12MP sensor but you don't get 12MP resolution from its photos due to:

- Noise reduction removing fine details

- JPEG compression also removing fine details

And most importantly:

- Poor quality lens that cannot resolve fine details onto such a small sensor. The image sensor in the Satio is not much larger than 2 matchstick heads side-by-side. And on this you project an image with 12 million pixels. To get full resolution you'd need very expensive optics. Are you ready to pay for this? Most people aren't and camphone makers like realise this and compromise on the quality to keep the cost at acceptable levels.

Also, if you have to compare, 5mp to 12 mp then you have to resize 12mp picture to 5mp size and then see the details retained not resize 5mp to 12 mp.

Resizing from 12mp to 5mp will be the same as we're talking about the same picture expanded in two different resolutions, I also tested it.

About the megapixel myth, I know about it and I understand it, however, it is not supposed to be like this, literally. Usually, upgrading for a higher megapixel camera does not worth it unless we also get better optics and sensor, in this case, we are completely cheated by see as there are effectively no improvements in the image.

I'll make make a few comparison shots soon, with the 12mp Satio against the 12mp Nokia E72. And I bet that N72 will perform better at 12mp.

Now some examples comparing Satio's 12MP to 5MP, this time I downsized the 12MP ones to 5MP.

As you can see, there is absolutely no detail lost and images are equalty good. So, I think there is no point in using Satio's 12MP setting as it will only get your media browsing and in camera operations slower. Satio is nothing more than a fine 5MP camera. Oh, and I'm curious about Pixon12 and N8.

The Pixon 12 hasn't got a big sensor so it won't be a big difference.
The N8 however would be cool to see.

GSMArena posts resolution charts in their camera phone reviews. Here are full size crops from Nokia N8, Samsung PIXON12 and SE Satio, side by side:



And for comparison with two 5MP phones, scaled up to 12MP, here is Nokia E72 and SE C901:

@zide thanks for the new set of snaps 12mp rezide to 5mp.. if you compare them side by side, you will realise that 12mp rezided contains more details compared to 5mp. look at the last indoor picture containing the brush, you will the big difference. Same is noted in the outdoor ones which are bit at a distance. Also, the road has got more details specially near the cobbled road on left hand bottom corner in your first set.

AbuBasim's post makes it clear further.

Now that's something!

The difference is so vestigial that I really think that's caused by the stronger JPEG compression (note that even after resized 12MP photos are almost 60% bigger).

Anyway, I tried to open a thread with some Satio vs E72@12MP but moderators started bugger me.

Here it is:

Yeah, everybody knows that MPs don't don't matter that much but in the end we all get our low MP phone replaced with a higher one. Now some samples comparing Satio to E72 with 12MP (expanded using Windows 7's paint) and one comparing Satio at 5MP with E72 also with 5MP:

All with auto-mode (except the Daylight WB):

E72 12MP:


Satio:


E72 12MP:


Satio:


E72 12MP:


Satio:


E72 12MP:


Satio:


E72 12MP:


Satio:


Here is Satio at 5MP:


E72 5MP:


Conclusion:

E72's shows more detail but also more noise and it seems to me that Satio is a fake 12 MP phone as it's capabilities are on par with E72's 5MP sensor. This way all good 5MP phones, such as C901, 6700, Elm, etc, could be advertised as 12MP phones because their are as good in 12MP as Satio.
Any way, I'm selling my E72 and I'll keep my Satio manly because of the month album gallery, camera cover, xenon and more accurate auto-focus and ISO selection in lowlight scenes.
