Camera problem (again)

[pmandrews]

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.

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?

[pmandrews]

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.
