FIELD: physics. ^ SUBSTANCE: presence of change of view in a video sequence is detected. The value of the backlight brightness level of the current frame in said video sequence is determined based on image characteristics in said current frame. Said value of backlight brightness level is filtered by a first filter when change of view is defined as close to said current frame; and said value of backlight brightness level is filtered by a second filter when change of view is not defined as close to said current frame. ^ EFFECT: filtering the backlight brightness level of a display using an adaptive filter based on presence of change of view near the current frame. ^ 20 cl, 98 dwg |
