Could you give me an idea of what you mean in terms of C or from the Linux userspace?

I'm not actively working on the mt9v032 driver anymore, but I can still try to help you. I would recommend CC'ing the linux-media@xxxxxxxxxxxxxxx mailing list when requesting help from the community, as other developers subscribed to that list might be able to assist you as well. The MT9V032 sensor doesn't seem to have per-component gains, so I'm not sure you would be able to fix the problem through the sensor driver. You could however use the image processing feature of the OMAP3 ISP, and in particular of the preview engine, to set per-channel gains or perform other processing that could fix the problem. -- 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
