1. A method for adjusting motion blur, said method comprising: first determining an inter-frame object displacement for each object in a left eye image frame pair; second determining an inter-frame object displacement for each object in a right eye image frame pair; third determining a convergence shifting field between each object in said left eye image frame pair and said right eye image frame pair; fourth determining an amount of motion blur responsive to said inter-frame object displacement for each object in said left eye image frame pair, said inter-frame object displacement for each object in said right eye image frame pair, and said convergence shifting field between each object in said left eye image frame pair and said right eye image frame pair, wherein said fourth determining act weights each of said inter-frame object displacement for each object in said left eye image frame pair, said inter-frame object displacement for each object in said right eye image frame pair, and said initial convergence and said corrected convergence and wherein said weights are in a range from 0.9 to 1.1; and adjusting said motion blur for each left eye image frame pair and said right eye image frame pair by said amount of motion blur, wherein said adjustment is an increase or decrease in said amount of motion blur in both the foreground and the background objects.
