Yeah, I'm not saying it's only your phone, just that the issue is more pronounced on some than others. I saw quite a wide variety of quality between handsets in K750 handsets. When I say wide, for example I saw cameras with virtually no white lines in low light, and others with white lines so bad the photo was completely unusable. This is despite them being flashed with identical firmware. So unfortunately I can't be too sure of SE's quality control when it comes to camera modules (perhaps the blame is Sony's?)

However that said I'm still not sure whether I don't get the problem badly or if my expectations are just lower! I will look through my photos again. As I've said before I don't deny I get the affect, but I've only been feeling that it's an occasional thing, no more concerning than any number of other cheap digital camera issues that crop up in even the best camera phones (aka the K800).

Maybe it's an aliasing affect that arises in only very specific circumstances?

Hellvy, you have definately picked up on what I'm seeing. Thank god - I'm not insane.

Max, once you start looking I'm sure you'll find the jagged edges affects more photos than you think. Especially if you look at them at full size on a 17-19" monitor. I wasn't really that aware of it until I took photos of my new car. And bang there they were ruining the picture. Then I started looking back at my photo's with more scrutiny and found it affected so many images in one way or another. i.e. Cats whiskers, stems on flowers, fine branches on trees, leaves, building ledges, the hands on clocks, numbers, edges on paper, etc, etc.

The reason I am picky is because I don't print my photo's. Printed at 6x4 you'll probably never see the jagged effect. But, I prefer to keep my photo's organised on a computer and viewing them on a computer. I can honestly say I have never seen anything ruin photo's so often in this manner as the K800 - not even those from 10 years ago. The more you look at K800 photo's the more you'll be disappointed. I also tend to find pictures have un-natural looking outlines and I agree with you, Max, that photo's do look like water colour paintings. The grid lines that bugged me on the W800/K750 are not as annoying as this. And, you know what - you can actually take photos with the W800 and get a similar jagged effect - if you use digital zoom. What does that say about the K800. If it's not a driver issue then the sensor must not be that good.

So, I am really hopeful that we can somehow figure out something that will overcome the excessive jpg compression, improve image quality and colour. I plan/hope to do some more testing and would like to better understand how the driver works. Namely, I want to figure out why increasing the compression to 95 results in smaller file sizes. Why decreasing the compression figure to 85 results in a larger images. Is the camera set too sharp? Do any settings actually make that much difference and if so, why. It may take some time, and I may achieve nothing, but i'll give it a good shot and hope others will continue to experiment as well.

That's what i'm trying to say. It's anti-aliasing process not sharpen setting, sorry -_-'


hmm.. that's quite different from my view, mongoose. I don't print photo paper often too. But i use print-out photo paper as reference. If the picture on paper looks good, i don't care much about what it's displayed on screen, strange color, noise, jagged edge.

I always think that monitor screen give much more detail than print-out paper (i'm still using old-time 17" Trinitron monitor ). So any artifacts can be revealed there. Pls note that i'm not a digital camera guy. Just k750/790 user fooling around. May be i have a narrow point of view about this stuff.


Oops, that's hurt. But you still believe in the power of K800 right?

Anyway, may be this anti-aliasing setting thing is hiding somewhere in the camera driver. Waiting for you modder guys found it

mmhmmm, unless youtube changes uploaded videos resolution, but that is not our phone's video size.

Well there you go. I have done some research on anti-aliasing and it perfectly describles what I am noticing. So, there's another avenue for me to look at.

aliasing is common to all digital cameras, even in some circumstances quality digital cameras can produce aliasing. This is why I've tended to discount the aliasing - it's a disappointing phenomenon, but one I've noticed in all the digicams I've ever used.

The aliasing I've noticed in K800 is not that unusual, however some of the examples you gave are quite bad and I haven't had that with my K800. For example the playground slide, that's an appalling case of aliasing and I haven't had anything near as noticable as that.

btw, sharpening worsens the aliasing affect. Softening improves it but at the cost of detail.
