Correction of manufacturing allowances 

 

For  fine corrections of the image window, offset parameters in X and Y directions are 
needed. With the X_OFF and Y_OFF parameters, the manufacturing tolerances of the 

centering of the optical axis on the sensor can be corrected. For ideal centering of the 
optical axis of the camera on the sensor, the following values of X_OFF and Y_OFF are 

used. 
 
X_OFF = ½ (1024 – 752) = 136   

Î

  88H 

Y_OFF = ½ (1024 -  582) = 221   

Î

  DDH 

 

 

 
Based on these ideal values, the real values are adjusted upon factory delivery. X_OFF 

and Y_OFF are stored in Registers 34 and 36. The maximum value of X_OFF and Y_OFF 
are X_OFFmax = 255 und Y_OFFmax = 255.
