Claim of US Patent No. 9,299,297

1. An image display apparatus for displaying an image on the basis of image data, the image display apparatus comprising:
light emitting unit which has a plurality of light sources for performing light emission that can be independently controlled
respectively;

setting unit which sets light emission control blocks for controlling one light source or the plurality of light sources with
a common light emission brightness;

brightness determining unit which determines the light emission brightness of each of the light emission control blocks on
the basis of the image data; and

control unit which controls the light emission of the light emitting unit for each of the light emission control blocks in
accordance with the light emission brightness determined by the brightness determining unit, wherein:

the setting unit sets a size of the light emission control block of the light emitting unit depending on an amount of motion
of the image, and the setting unit sets the size of the light emission control block so that the brightness determining unit
can determine the light emission brightness of the light source of each of all of the light emission control blocks within
a predetermined period of time.
