Yes. I found that the value 0x00030003 gives me a perfect picture. This means 3 rows 3 cols I guess. Photoshop doesn't want to open it but Raw Therapee and IrfanView open them without problem.

That is very strange indeed - I haven't heard about a new type of 3x3 bayer sensor pattern (not sure how it would even work).

Can you upload a sample DNG file and post a link - I'd like to take a closer look at one.

Thanks,
Phil.

I really don't understand this. Now I tried to play with that number and didn't make any difference, even with the original value. So for now I leave it as it was. I did a gmake clean and recompile, probably this fixed something.

I uploaded a sample DNG here: http://www.zshare.net/download/89869014056297be/

I see no problem in the file, colors look ok.i test with picasa and silky pix free

maybe you should switch your camera to series mode and press and hold shoot button, so 6 images are record.If some of them are wrong mostly every 2. , then your buffer address code is wrong.

also verify if same number of raw and jpg is record and raw and jpg have same number.
best you use option that RAW are in same directory as jpg, so you can see this easy

Here's the latest binary if someone is interested in testing it.

DNG and Create badpixel.bin are working now.

Check the wiki for more info on this. It's an array of locations of badpixels that get corrected after the shoot. For my camera Create badpixel.bin reported 27000 bad pixels.

The black borders are visible only when no zoom is used. In Photoshop you can use the lens correction profile for Samsung WB2000 (distortion 200) to fix it or correct it manually.

Fixed a bug today that caused a camera crash in continuous shooting in RAW mode. http://www.zshare.net/download/89997598e62c1670/

I also found new bug, sometimes the camera crashes when switching from REC to PLAY mode.
