The height and width just specify the portion of the array to read they shouldn't actually affect what resolution the sensor is outputting. As far as i can tell the main issue you are having is that the sensor is outputting a full 1280x1024 image whcih would explain why you are getting a zoomed in upper corner of your image since the bridge only takes a 640x1480 window ith no scaling enabled in VGA mode meaning all you see is a small part of the larger 1280x1024 image.
We of course want it to be giving the bridge a 640x480 I would start looking at the reducer registers for context B whcih is what are bwing used particularly the ones for the output size. They default on your sensor to 1280x1024. Try changint them to be 640x480 instead and see if it helps at all On Wed, Feb 4, 2009 at 4:21 PM, Korvin <[email protected]> wrote: > > On Thursday 05 February 2009 03:16:52 Brian Johnson wrote: >> I think the issue with the mt9v112 has to do with the fact that that >> sensor has an active window of only 640x480 pixels where as the sensor >> on your camera has an active array of 1280x1024 pixels try mosifing >> the register writes for regissters 1-4 to adjust the size of the >> window inparticulare you can likely get rid of the black area by >> modifiering registers 1 and 2 whcih are the x and y start postions for >> your window registers 3 and 4 give it the wifth and height. > > Right!
