pixel value

Postby pcls1026 » Tue Jan 09, 2018 3:27 pm

Hi,
I want to read the "raw intensity" value of the bayer red filtered pixels.
Thanks

Hi, that's actually not supported. I didn't think anyone would be interested in bayer, will add it to the next release.

Thanks,
If I use image.get with QVGA and RGB565, I think the R in the tuple (R,G,B) would be close to what I'm looking for. What do you think?

If you just want the red value of every pixel then yes. RGB is interpolated from bayer but it's not exactly the "raw" value.

If you get the time I would appreciate the ability to get the red intensity value.
Thanks

A "REDO" of the previous reply.
