focal length in correlation to image section

try it yourself at www.nima-koeppl.de

Enter values for width and distance in the left boxes to get the nessecary focal length in dependance of the camera chip form factor. Calculations are based off width and distance. Aspect ratio and height are only provided as an orientation.
