θ is the angle of disparity between the channels For
definitions of A B C D see the above figure
Calculating with this formula the angle of disparity is
θ arcsin( ) or θ arcsin ( )
If the elliptic main axis is within quadrants I and III, the angle
ofdisparity should be within quadrants I and IV,i.e.inside
