i’m trying to get raw pictures from my ps eye on linux (patched gspca-driver from kaswyweb), but unfortunatly did not succseed til now. I have got datasheets from both, the ov7220 and ov534 chip and changed the initial settings of some registers to bayer raw 8bit, but i only get very noisy pictures. sometimes one can see objects but all coverd with noise. after matching a bayer pattern on the greyscale picture i get colered noise. there are example pictures attached (original greyscale image and this image multiplicated with a bayer pattern). does the bayer raw picture have to look like this or is the raw mode not correctly initialized? what do i have to do to enter bayer mode? There is not much explanation in the datasheets, so if you could help, it would be great.

Thank you

That doesn’t look like Bayer pattern. For comparison you can install the CL-Eye Platform SDK and use Bayer mode settings to capture images and see how it looks like. Enabling Bayer mode involves setup of many registers and its not trivial. Having a reference image to go by will hopefully help you in your work.
