As part of our transition to the brave new 3D world of KMS, we are moving the AWB algorithm off the quad processors. These quads are used by the new 3D driver from ARM space, and allowing the camera AWB (firmware space) to use them as well is not very efficient for either party.
So, we now have a baysian statistical AWB algorithm that runs entirely on the VPU. This can be tested out by running `sudo rpi-update' which will update your firmware to the latest test version.
We would be grateful if people could try out this new AWB algorithm. There will be some differences, but it should match up fairly closely with the existing version. If you find a major difference we would be very interested in seeing comparison images, preferably in RAW format. (e.g. raspistill --raw option)
You can easily switch between AWB algorithms as follows:
Code: Select all
vcdbg set awb_mode [0|1]". 0 for old algorithm, 1 for our new algorithm. Defaults to our new one.
