I've noted an odd thing about using the subframe feature of QGVideo32 with a QHY5V: The brightness of the images is reduced by about 20% (at least in the following example). I created 2 images to demonstrate the issue:https://owncloud.geeq.de/public.php?service=files&t=65741eea21d23dbeae6504aa876c75adhttps://owncloud.geeq.de/public.php?service=files&t=f28c3c006c1c21c07a69c53f86189af6
(I used a simple pinhole setup and took a few frames of the room lights while holding the camera in my hands. This method is not perfect but this effect also appears while taking photos of planets.)
Does anyone know whether this is a bug in QGVideo, the driver or expected behaviour of the camera? I would like to fix this if necessary by myself, but a place to start would be nice.
And another question, because I do not have my camera at hand: How's the MT9V032 connected to the Universal Serial Bus?
