Abstract
The present invention in its first aspect provides an image display apparatus capable of controlling, for each block obtained by dividing a region of a screen, a backlight emission brightness based on image data of an inputted frame. The image display apparatus includes: a detecting unit that detects a block in which a predetermined object is displayed; a determining unit that determines an object block that is a block in which a background and the predetermined object are displayed based on a detection result by the detecting unit; and a control unit that controls a backlight emission brightness for each block. The control unit approximates a backlight emission brightness of the object block to a backlight emission brightness of another block in which the background is displayed.
