Abstract:
An image display apparatus includes: a light-emitting unit having a plurality of light sources capable of controlling emission brightness individually; a display unit that displays an image on a screen; and a control unit that controls the respective emission brightnesses of the respective light sources according to images of regions on the screen corresponding to the respective light sources. When a difference between an image of a subject frame and an image of a past frame earlier than the subject frame is caused from movement of a predetermined object, the control unit suppresses the emission brightness of a light source corresponding to an image region of the subject frame brighter than that of the past frame from changing from the emission brightness of a light source corresponding to this image region of the past frame.
