Image Quality Evaluation for Motion Blur Reduction Techniques
To evaluate the performance of motion blur reduction techniques for displaying moving image material on LCDs , two subjective experiments were designed, In the first experiment the effect of frame rate was investigated for a continuous backlight ( CB ) and a scanning backlight ( SB ) system , using motion compensated temporal up-conversion for the video material. Additionally, for the up-conversion to 100 and 120 Hz, motion compensated interpolation was compared to frame repetition. In a second experiment, motion blur reduction techniques using a continuous backlight, a scanning backlight , or smooth frame insertion were mutually compared at several fixed frame frequencies. From these experiments it can be concluded that at any frame rate above 50 Hz a scanning backlight system yields a significantly better image quality than a continuous backlight system. The difference is most obvious in the range from 60 to 90 Hz, yet still existing at 100 and 120 Hz. Smooth-frame insertion is considerably less preferred in terms of image quality than a continuous or scanning backlight with motion compensated up-conversion at the same frame frequency.
