I tried to decompress 13M RAW files with DPCM 8-10, DPCM 8-12, RLE and A-Law... no go :( I'm struck because of some oddities I'm noticing. The IMX206 sensors send RAW10 or RAW12 (or DPCM 10-8) datas to the A7LS. So is the compression done by the image processing DSP and not by the sensor? And...

I found another document about DPCM image compression... and this is a confirmation that this compression method it is patented :( https://www.google.com/patents/US20040202375 I could try (and probably I will try) to code the algorithm and test decompression in raw2dng, but I fear I cannot...

Hi hanzodeceptor, I'm in the same condition. I'm still trying to understand... it's really difficult bacause datasheet of CCD sensors, bus and compression formats are confidential and often released under NDA. The only one documentation I found (and somewhat usable?) is a draft of CSI-2...

To avoid cross posts, I'll continue on the topic The Definitive [Xiaomi Yi RAW] Guide.

I'm investigating about using Xiaomi Yi RAW files under GNU/Linux. I noticed they are RAW RGGB Bayer so cannot be open directly with dcraw/ufraw/rawtherapee. I found the website of raw2dng and the source code of the last available version is public. http://e2500.narod.ru/raw2dng_e.htm It...
