I've never used OpenCV on Android, but, if I understood correctly the problem, I would give a try at the VideoCapture::set method to change the CV_CAP_PROP_EXPOSURE parameter. Though this would be a pretty rough solution to your problem.

If you want to display only the ROIs, I would suggest you to: Create a blank new output image For each ROI create a mask image from the ROI and use copy() with the mask as 3rd argument to copy the ROI from the input image to the output. As Steven pointed out, the C++ interface makes everything better.
