1. A method of selecting an optimal viewing angle position for a camera, comprising: determining a first quantitative score for a first viewing angle position of the camera using pre-selected regions of interest ( 205 , 206 ) as reference areas ( 101 ), the determining being performed in accordance to a pre-defined quantitative score rule, adjusting the angle position from the first viewing angle position towards at least one second viewing angle position ( 103 ), determining for each at least one second viewing angle position a second quantitative score ( 105 ) in accordance to said pre-defined quantitative score rule, and determining a target viewing angle position ( 107 ) based on the determined quantitative scores.
