A display apparatus according to the present invention, includes: a display unit configured to display an image based on display image data generated from input image data; a control unit configured to control emission brightness of a light source of the display unit; and a detecting unit configured to detect a user operation for specifying a position in the image, wherein the control unit controls the emission brightness of the light source of the display unit in accordance with a gradation value of the input image data corresponding to the position specified by the user operation, to emission brightness that is lower than set emission brightness or to emission brightness that is higher than the set emission brightness.

Display apparatus and display method

Disclosed is an image output apparatus that outputs a plurality of image data to one or a plurality of image display apparatuses capable of controlling amounts of light of backlights, the image output apparatus including: a determining unit configured to determine whether the plurality of image data satisfy a predetermined condition; and a controlling unit configured to control, when the determining unit determines that the plurality of image data satisfy the predetermined condition, the one or the plurality of image display apparatuses such that either or both of amounts of light and number of light emission control units of the backlights used for display of the plurality of image data are the same.

Image output apparatus, control method therefor, image display apparatus, control method therefor, and storage medium

The present invention resides in an image display apparatus for displaying an image on the basis of image data; the image display apparatus comprising light emitting unit having 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 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 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.
