Image display apparatus and method of controlling same

A method of controlling an image display apparatus including:

• a light-emitting unit having a plurality of light sources capable of controlling emission brightness individually;
• and
• a display unit that displays an image on a screen by modulating light from the light-emitting unit, the method comprising:
• controlling the respective emission brightnesses of the respective light sources according to images of regions on the screen corresponding to the respective light sources, wherein
• in the controlling, when a difference between an image of a subject frame in which emission brightness is to be determined and an image of a past frame earlier than the subject frame is caused from movement of a predetermined object, the emission brightness of a light source corresponding to an image region of the subject frame brighter than that of the past frame is suppressed from changing from the emission brightness of a light source corresponding to this image region of the past frame.
