Image rendering issue

I just downloaded a map from Sugarbush Ski mountain in Vermont so I'd have it handy when skiing there. Unfortunately, when I zoom in the image is so blurry that I can't really read the text. The same map looks fine on my desktop computer.
Unfortunately I can't post a link to the map because the XDA developer's site won't allow me to (you can't post links until you've made 5 other posts to the forum). Just google 'Sugarbush' and you will be able to find the static trail map image. Someone else who's been around here longer could post the link in a follow up message.
I've tried viewing it in multiple programs (standard browser, Dolphin browser, gallery view), and all show the same problem.
Can other Nexus one owners confirm that they have the same issue?
Any suggestions?

I think android might downsize/downconvert images automatically so you will not be getting the original resolution of the image.
UPDATE:I can confirm that the image is definitely lower resolution than the one that appears on desktop. Here is the link:

I just mounted my Nexus via USB and checked the file that I'd downloaded to it. The actual file stored on the Nexus One is full resolution and displays fine on the PC. It's just on the Nexus that it fails to display well.
This seems more like a bug then a feature.

I just made a simple 2000x1000 graphic with two strings of text, one aliased and the other antialiased with a crosshatched background.

You can clearly see how blurry both lines of text and the crosshatches are when you zoom in on the android browser or in the gallery. It looks like there is either a huge amount of compression being applied to the image, or that the image is being resized for viewing and the blur effect is due to a loss of detail that you don't get back when you zoom in.
I don't know if imageshack has a bandwidth limit, but here is the same image on imgur.com. You can see the extra effects of blurring, though you also see a lot of jpeg artifacting from the high compression imgur apparently automatically applies.

Only 2 questions I couldn't find the answer to...

I came from an HD2, and what HTC wrote over in WinMo 6.5 I thought was great, especially the gallery app, which cleared up an image when you zoomed in. I've noticed that this phone does not do that. When I zoom in on a picture I took it just turns all fuzzy, like it's been compressed or something. I know the pics are high res cause they look great on my computer, but I just can't understand why they don't clear up when you zoom in. Anyone else experience this? The only other issue I've noticed is that every once in a while I'll open an app up, lets say the web browser, and it pops up and then just force closes. Several others I know with a Vibrant/Captivate are having this problem as well, and I was just curious if anyone knew the cause. I'm totally new to Android so please pardon me if these are dumb questions.

for the second half of your post you should get your phone replaced.
there have been a couple people on here that had that issue with "sticking" buttons so apps would randomly close or settings would popup.

As for your first issue, it sounds to me as though you are zooming into the thumbnail version of the picture. Perhaps the full high-res version is actually found in another pile/folder under the gallery. I don't think the thumbnails are generally viewable separately, though I do see a lot of other media gathered up from various apps which can be kinda annoying.

No I promise I'm not zooming on the thumbnails, I'm clicking the folder with all of my pictures in it, and it'll let me zoom in on them, but they never clear up. It's not the camera cause the resolution is right, just the zooming isn't working properly. it's weird, and frustrating.

I definitely don't have the camera problem. I tested it with photos I took as well as wallpapers in my gallery. I assume you are using the gallery app, right?
If you're getting FCs on stock apps you may want to just do a factory data reset (settings/privacy). It happens occasionally to all android phones and the only sure fix I've seen is a reset. Make sure you're not using task killers or home replacement apps (pandahome, openhome, etc) as they can cause a lot of FCs in my experience.

You might have your camera resolution on lowest settings. Try a higher setting and let us know. The default resolution is 640x480.

Checked the resolution of the camera and the pictures themselved and they're both 5MP, so I really don't know what the problem is now. It is rather frustrating though, when I zoom I want to see the details of the image not a fuzzy picture. Another thing I've just had happen to me is trying to copy over a 4.5GB MKV file at 720p I got the message "The file 'Up' is too large for the destination file system" I don't get that cause I have 6GB free on the phone and 6GB free on the 16GB micro SD. My phone hates me :'(

the 4.5gb MKV isn't a Samsung issue. It's a filesystem issue, relating to the default filesystem used on the sd card memory. FAT32 has a file size limit of 4gb.
It might seem a bit frustrating that you will have to re-encode that huge MKV, but considering that you can count on the fingers of one hand the smartphones that would even be able to smoothly play the video in that container in the first place, it's a small price to pay.

I know the phone could play it, it chews through my 720p copies of Top Gear without so much as a hiccup, and they're nearly the same bit-rate. I think you're right about counting the phones that could do that though because my HD2 didn't have a chance. I didn't know fat32 had a file size limit though, that's very useful information and thank you very much for that. Any ideas on the gallery app problem?

I had/have a HD2, and now a Vibrant that I am using.
I know what you are talking about with the pictures looking pixelated on the Vibrant when you zoom in, but look fine on the HD2. I too, would like a solution to this. Maybe another app does this.

I know exactly what you're talking about and it really is quite annoying. As if losing the flash wasn't bad enough, now even my old photos look bad on it. I've figured out firstly that the stock android gallery app has a 16 bit limit but that's not the issue I'd imagine. What I believe to be the culprit is that, as far as I can tell, what the image viewer does is it actually automatically downsizes all your photos which would explain the pictures' butchered quality. Of course it's just a theory but it seems to check out. Unfortunately I have yet to find a decent replacement app or a solution thus far. And not to dash your hopes but I hear the problem also exists in froyo. Kinda disheartening for such an awesome multimedia phone.

+1.. I also know what you mean, I had the HD2 and zooming in on the pictures on this phone sucks!. I am sure there is an image viewer somewhere that would work well

Yes! Glad to hear I'm not the only one with this issue. I was beginning to think I was alone! I am by no means a developer, but I think it's probably the scaling algorithim, though it would be interesting to check it out on another phone running 2.1. Next time I activate a Captivate at work I'll check that as well, it'd be really weird if that one worked correctly!!

I've figured something out. When you look at photos in the actual camera app, and zoom in that viewer, the pictures look fine, it's only in the actual gallery app where the zoom doesn't work properly...

I definetly do not have the issue with zooming in on pictures (camera or gallery) and I have yet to have a FC on any app. You mentioned the browser, any other apps FC'ing on you?
Have you done anything (other than root if you have)?
Are you using a TK?
Can you give more details?

I know what you mean by zooming the pics. Try image viewer, its awesome and zooms in great

Well it's only the browser that's done it, and it's only happened once to me, so I'm really not worried about that one. A power cycle took care of it right then and there. As for the zooming, like I said in the camera app itself it works fine, but in the gallery app it's not too good. I'm not rooted (yet), and I have no task killer because I've heard more bad things than good things about those. Idk how else to describe the problem, it just seems like when I zoom in it's like the file is a very low resolution and gets very pixelated and when I check the properties I know it's a 5MP picture, so idk what's going on.

Something I never noticed so I just tested and you're right!
It's the way the built in gallery app works. It creates a thumbnail of all images and that's what it displays. You can even see the thumbnail images if you explore the phone memory. The only way around it is to download and use a different image viewer.

I suggest large image viewer! It is a bit spartan in terms of features and ui but it has the best image viewing of all the apps I tried! Btw the default image viewer basically makes a lower res bitmap of all your pictures and it's impossible (I think) to actually view the original images from within the gallery app. Why it would do this? I have no clue, seems like poor programming to me. Perhaps it's the cost we pay for the nifty though relatively pointless 3d effects.

images in browser/apps displaying in low res

Hi
just got a galaxy s on tmobile in the UK.
It's good but it seems that lots of images in the browser and displaying in low res, they all look blocky.
It's happening in apps too - the thumbs of peoples faces in facebook are blurred/blocky, images from the engadget app are blocky etc.
I've compared to another galaxy S and the images on that look fine.
Would anyone have any idea whats causing it? thanks
Edit - It seems to be intermittent too. For example, if i do a google image search, the thumbs are sharp, but if I click on a pic and it goes into the slideshow view all the images are REALLY blocky. If I click the link to the original page were the image is coming from the image loads up fine.

It seems to be my carrier, tmobile.
When i put other sim cards in the phone it works fine.
Very annoying, makes buying a nice phone like this for web browsing kind of pointless.
Anyone know of a way to bypass this?

[Q] How to fix screen resolution?

Hi everyone, this is my first post, I'm not sure if it's been posted yet. I'm a photographer and I do not use the camera on my HD2 because I just import my photos to the phone so I can display samples of my work to potential clients. The sharpness of my photos when displayed on the device was the main driving point for me purchasing this phone. One thing I noticed however, since flashing my photo to Windows Phone 7, my pictures are not sharp at all anymore. I just loaded a picture on to my friend's WinMo 6.5 HD2, and there is a drastic difference. I've seen posts about the camera taking blurry pictures, but I haven't seen any that just indicated general blurriness on the screen. Is there a fix for this or will I have to give up my WP7?

That's odd, my transferred pix are excellent, maybe you should reload WP7? Not much help I'm sorry but it doesn't take long to reinstall...

what res are the pictures?

I had the same problem but it seemed to only happen with photos that I transferred to the phone. I never found a fix, though I do not think it is a resolution problem with WP7. The issue might exist in the file transfer itself; perhaps a Zune issue? Anyway, I never found a solution so I'm back on 6.5.

Try this:
In the Zune software, go to
Settings > Phone > Pictures and Video
and set "Image Quality" to "Original"

I tried the settings in Zune and those settings were already selected. The resolution is 3744 x 5616, but it doesn't matter the photo size, they all still aren't crisp as they were before.

try changing them to 1024x1024, maybe wp7 is lowering them automatically because of how large they are

even the ones i had at 950 are blurry, no matter what photo I load into it...same result.

**Update**
Since my last post, I have flashed back to 6.5, loaded some photos on. Image resolution is far superior. Loaded WP7 back on, [a different ROM], and still photos are still not a sharp. Is it possible that the photos do not render as well in WP7 as they did in 6.5?

strange, i use both zune for pc and windows phone connector for mac to transfer my 12mp photos from my cannon450d and they are reasonably sharp for a screen with limited pixels.
Even my photos from facebook look reasonably good (not much difference on the small screen to be honest)

Yeah for me, whether it's from my Canon 5D Mark II, or my 50D, same problem. At this point, I just won't load any photos on the device! It sucks because my main reason for purchasing this phone was photos, and also that ability to put different ROMS on it.

Email a photo to yourself, and save it on the phone. See it works that way.

It may be that the stock wp7 picture viewer doesn't display them as sharp. Maybe you can find another photo viewing app in app store and see if that makes any difference.

[Q] GS4 Facebook photo upload: image size issue?

Anyone notice that the photo uploads to facebook are quite small in size?... as compared to my previous HTC/ Sony phones.
Photo quality is great... it's just that the my previous phones uploaded 'higher-res'/larger photos

Here's an illustration all scaled to the same size.
Funny thing is.. after i transfer my photos onto my comp, and upload them using my comp onto facebook... the photos become much larger.. it seems like uploading thru a mobile device somehow shrinks it? esp for the s4?
Anyone?

Bump for replies!
It seems like somehow the GS4 uploads photos to Facebook using settings that are not optimal...
I don't seem to have this problem on the HTC One... the photos uploaded from HTC One appears quite large when viewed via the facebook photo viewer

Trya a different facebook app, see if the problem still exists ... or use the webbrowser interface facebook to upload

I tried uploading via the web browser and it turned out larger than if I uploaded it via the facebook app..
This is so strange. So i went to uninstall facebook and re-installed it again... and reuploaded the photo.. it turned out to be smaller again.
I think there is something about the way the facebook app uploads photo that somehow prevents it from achieving the optimal upload size at max resolution.. this is so weird.
I wonder if anyone here experiences the same problem.

Me too, hence my thread I started here:
http://forum.xda-developers.com/showthread.php?t=2271139
...As when I searched on "Facebook Image Upload Issue" before starting my thread, according the the site, nothing came back specifically for S4 devices, though plenty of older ones, so sorry about the duplicate post. Mine has a poll though, so that should be interesting to see how it pans out...
Look like it is indeed a Facebook issue... POS...

- That's because with it's "UltraPixels", the HTC One actually takes photos in a very low resolution.
But I don't just think it's a size issue - it's an S4 issue itself, because if you first shoot the image in a lower resolution, say just 8MP on the S4, then the photos are STILL downsized, but weirdly, not by the same amount - so the end result is that either 13MP or 8MP will still cause a down-size problem, but images shot in a lower original resolution, will actually be uploaded slightly larger - 13MP images get shrunk smaller than an 8MP one does, but BOTH get messed up though.

GAAAAHHH - Facebook are STILL suffering this issue... Anyone know of any easy workaround. The resizer one is handy, but not so good for lots of party photos that need uploading there and then...

confusion
I am really baffled myself. You get the phone with one of the top 3 cameras in the market and uploads it to facebook with a quality worse than iphone's 5mp bad impression of a camera. The amazing thing is that the whole internet is not buzzing with this. Numerous google searches coming out with none to 0 results. Please, if anyone finds a fix or at least a reason for why this is happening let the rest of us know
