I've implemented simple AE and AWB code for the OMAP3 ISP. You can find it at http://git.ideasonboard.org/omap3-isp-live.git (look at the iq_aewb_process function in iq.c). The code should be considered as a proof of concept, in a real system you will very likely want to implement more complex AE and AWB algorithms. I'd be happy to receive patches that make my trivial implementation smarter :-) -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
