A few months ago there was a number of threads about the problems with the HTC Alpine camera, and someone found that there was a fundamental hardware fault which causes alternate lines in the picture to be swapped, thus the appalling quality of the pictures.
I also recall someone posting a small program (or a link to it) which would take an afflicted BMP file and correct this problem, but despite searching the forum I have failed to find it.
Would anyone be so kind as to remind me where to find this program, or is there another solution to this fault?
Thanks in advance.

Thanks, I tried one of the ROM images kindly provided, but the problem with the line-swapping on the pictures is still there.
In deperation I spent ages searching my very disorganised PC for that little program I found on xdadevelopers which swaps alternate lines and thus restores the pictures to the glory that HTC's abysmal engineering deprives them of.
Eventually I found it. It is called BMPChop.exe. It is a command line program to run on a PC, which swaps alternate lines then compresses the BMP file into JPEG, with the chosen compression level. The pictures look so much better once this has been done!
If anyone is interested, I can post it on this forum again (which is where I originally got it from).
But going back to the supposed camera-fixed ROM images, what has been changed other than removing the o2 camera patch? Has the ROM's author added his own patch to fix the line-swapping problem? It's just that I didn't find any improvement when using this ROM.
cheers
I would be interested to try the programme if you could post it on the forum, thanks.
Here it is:
many thanks. 8)
To be honest I can't see a difference between the 2. I took a picture with just a plain BMP file, converted it using the BMPChop and compared it with the new file and couldn't see a difference.
What command line are you supposed to use?
I used "BMPChop filename.bmp /100". The /100 sets highest JPEG quality. I have tried lower values but there is an obvious loss of quality.
The improvement in picture quality after running this program should be quite obvious, especially on diagonal edges and other line details, such as spectacle frames, which look jagged in the original images, especially if you zoom in a bit.
I've searched and read (and read and read) but haven't found a solution to this. Maybe I've missed it. If so, please point me in the right direction.
I upgraded my new Tilt with Dutty's Diamond V1 (WM6.1) ROM. It has a new camera (v 5.04, build 29195) installed. When running, I can take pictures just fine. However, when I click on the right-pointing arrow in the lower-left corner, it's supposed to link me over to the photo album but all I get is a black screen. At this point, I can press on the "windows" button and launch Today where I can see that the album has launched and is running, but when I select it, I only see a black screen.
Is there a fix for this?
i got the same issue
your camera works fine? where are the photos saving to?
The camera works fine. I can save the pictures to either the device or the storage card - both work.
Some pix
Just so it's clear, I'm posting a couple of pictures. I used MyMobiler to capture the screens which, unfortunately, does not capture the camera image in the first frame.
The first frame shows the screen (sans what my camera was seeing). The red circle highlights the "Album" button.
When pressed, I get what you see in the second - nothing but black. The phone's not locked up, however. It's just not displaying anything. No album - nothing.
And finally, in the third screen, you see that both Camera and Album are running. Album was launched, apparently, by the screen tap in the Camera application but doesn't seem to quite get it right when launched this way.
Ideas?
so you have a black screen when using camera, but it still takes pictures, if that is the case try another radio.

its not a radio problem. i think it has something to do with a broken album link in the camera application. im looking for a solution as well, as i am having the exact same problem on my own cooked rom

No. I don't have a black screen when using the camera. I see things just fine when using the camera. Works just like you'd expect. What you're seeing above in the first pic is an artifact of the screen capture program.
The anomalous behavior begins when trying to launch the album from inside the camera application. That's when the screen goes black.
My initial thinking was as mbarvian has floated - a bad link or some bad parameter passed from inside the camera app. I was hoping that this could be fixed with a registry edit, actually, but couldn't find a registry key that offered promise.
(BTW, I tried re-flashing the ROM but that didn't fix the problem. Just another data point to consider.)
So, nobody has a solution? Are others seeing this or just the two of us who have posted? I guess it's just something we live with until the day it's fixed?
Same problem same ROM...
when i had windows 6.0 i went on the htc website and downloaded 3 hot fixes for my phone ,then when i updated to the orange 6.1 version of win mobile i had the same problem as you ,( black screen on camera ) anyway i uninstalled the hot fixes ( they are not required on 6.1 version ) camera is now ok
Also, same problem... same rom.
stop taking pictures of only black things...

Well, if it can't be fixed, I may as well have a laugh over it, eh?

Yours may be slightly different than mine. I don't really get a black screen on the camera - only when I launch the album viewer from inside the camera application.
The "same issue - same ROM" responses at least give me a measure of affirmation that there is a known unresolved issue. For now, I'll just manually launch the album from the launcher where it seems to work, and avoid using the call from the camera app.
maybe using advanced config. and making sure the photos are saving to My Pictures might help

Set to that by default already. Tried swapping it to DCIM just to see what happened but that didn't work either.
camer w/black screen
after upgrading tilt to wm 6.1, my camera takes photos, but the screen is black, no preview, until AFTER taking the photo, then it appears briefly. is there a CAB fix for this. please help
I think it may have something to do with the version of the camera fix. I noticed the problem this weekend after updating to the ATT Official 6.1 ROM. Installed a newer version of Nadavi HTC Camera and when i went into the camera all I can see was a black screen. I'm using 5_0_4_2915 which seems to have corrected the problem for me.
where can i get this version that you tried? i am having the same problem
I have a weird thing going on..
When I view pictures using the Albums app and I have the unit sitting upwards, the image displays in landscape.
When I turn the unit sideways, the image rotates back as if the unit was upright.
Without hard-resetting... does anyone have any idea on how to go about solving this??
I am not running gsen, but I did have it installed at one point and it was working very well. Teeter, bubble level, and other tests work great.
Thanks in advance!
have you tried recalibrating it ?
there are a bunch of programs here that might help you do that (e.g. waterlevel)
Are you using GSen while _taking_ the pictures? I found out that some pictures themselves have been taken with the wrong orientation so it's not the album's problem but the pictures'. Try viewing a picture you upload to the phone and see if you have the same problem.
Thanks for the replies.
It was my understanding that the g-sensor wasnt able to be calibrated yet. I have bubblelevel and I used the calibration with that (but not recently).. so maybe that is causing my problem to begin with?
Does waterlevel actually calibrate the g-sensor or just the waterlevel software?
I dont have gsen installed anymore, it was giving me problem and never worked properly.
Okay I just realized something... I actually took the pictures while holding the camera sideways. So it would make sense that viewing the picture while the camera is upright is going to show the image on its side.. and visa versa when the camera is turned.
So is there any way to view a picture in albums with the camera turned on its side, and view a wide picture without having it turn the opposite way?
Try it, youll probably understand a little easier. Basically if the picture was taken wide, and you view it in albums on its side, it flips it the wrong way.
This is a known problem and I already reported it to HTC, not received a reply yet, but I hope they will be updating the Camera program so it takes in consideration the way the device is held when the picture is taken.
This is actually possible but the only one who can do that is the one who owns the source code, thus HTC.
Thanks for reporting on this Scotchy.. Good to know.
i upload some photos i take by kaiser, there are some white and blue line in the photo, appears some times, is there any solution to solve this problem? thx all.

I guess your LCD is faulty. I bet if you send an MMS the image is displayed right to the receiver's phone. I've already seen quite some LCD with this colour rendering problem. The solution is a LCD replacement. Also there are some displays sold on eBay as new that have the same problem. On a Touch Viva I owned i had to replace it 4 times before receiving a fully functional LCD!!
To be sure, you can try to install in your phone MyMobiler and then sync with your PC: if you see a difference between the phone colours and those displayed on your PC monitor, it's definitely a faulty LCD.
Also if you like to post a screenshot i'm able to recognise this kind or defect.
Bye
