[Help] Shading Correction, Camera v2 after Lens Removed

Hi, I'm recently exploring the possibility to change lens of the rapsberry camera v2 and/or remove the lens completely for some contact imaging. I removed the lens and lens holder of camera v2 completely with the help of a razor blade (would love to share details if anyone is interested). http://dri...

Re: Pi Camera V2 raw bayer data

That has done some processing on the raw already, although mainly just an unpack and shift down to 8bit. The original data is 10bpp Bayer, so you've lost 2 bits of detail :( Thanks. Do you think the argument "-D -4" in dcraw.c generates the 10-bit stored unprocessed raw image (though stored in 16 b...

Re: Pi Camera V2 raw bayer data

Happy Christmas - I've just hacked dcraw around to process the IMX219 raw images. Source at https://github.com/6by9/RPiTest/blob/master/dcraw/dcraw.c. I have NOT rebuilt the binary on there as I was hacking on my x86 machine rather than the Pi. There's no colour conversion matrix supplied, so the c...

Re: Pi Camera V2 raw bayer data

What is your command line to capture your raw image, PiCamV2-Raw-Chart2.jpg ? raspistill --raw -o PiCamV2-Raw-Chart2.jpg It's a little confusing because that is a valid JPEG file, but it is much larger than normal and also includes the RAW frame data appended at the end of the jpeg data. Hi jbeale,...

Re: Pi Camera V2 raw bayer data

Thanks for sharing -- indeed it compiles and works for your image. However, I tried with my raw images captured with raspberry pi camera v2 and it generates a random noise raw image (so there's something wrong with encoding). I was using the command below to capture raw images: raspistill -n -r -o ...

I've just hacked dcraw around to process the IMX219 raw images. github.com/6by9/RPiTest/blob/master/dcraw/dcraw.c Thank you! I can confirm that this compiles and works OK on a RPi. Color is as you say, a work in progress. Great stuff! wget https://raw.githubusercontent.com/6by9/RPiTest/master/dcraw...

Re: De-cap Camera v2 / Remove Lenses

Does anyone have tried to remove lenses on the new camera module v2 Yes. Quite a few people have changed the lens or adjusted the focus. To do this you need to carefully remove the small blobs of glue that hold the lens in place, then the lens should turn. You can do this with pliers, but some have...

Re: De-cap Camera v2 / Remove Lenses

I think I may be the only person to have destroyed my lens with pliers (but, I wiped out two of them). Using the right tool it's quite easy, and I think safe. You don't need to remove the glue at all. Just a slight twist of the tool, and the glue gives way with a little snap sound. From there it is...

De-cap Camera v2 / Remove Lenses

Hi, Does anyone have tried to remove lenses on the new camera module v2 (in order to change lenses or work with other geometry)? I suppose it's still glued as the v1 omnivision camera. Any suggestions on which edge/corner will be safer to cut? (Appreciated if there's a photo of decapping process or ...

Re: Is global shutter available for camera module v2

you can't get this resolution with a global shutter in this sort of price Yet.Give it a year or so. I'd say that's optimistic. Global shutter has been in an entirely different price category for as long as there have been CMOS sensors AFAIK. Also, if the info on this page applies generally, going t...

Is global shutter available for camera module v2

The new camera module with Sony IMX219 will be amazing if global shutter is available. Any idea how to get global shutter work?

Thanks!
