As we know, the resolution of RasPi camera is (2592,1944).
Is that possible that I only use part of the sensor pixels to obtain the image (automatic exposure mode)？
For example: the sensor area from left-upper corner (100,100) to right-lower corner (1100,1100).
The output image is only based on the pixels in this selected rectangle area.
Could someone give me some guidance?
Thanks a lot!
