Display apparatus and control method thereof

A control method of a display apparatus capable of controlling a backlight emission brightness for each block obtained by dividing an image,

• the method comprising:
• a determination step of determining, for each block corresponding to a background region, which is a region of a background in an image based on an input image signal, whether the block is a block which satisfies a predetermined condition;
• and
• a control step of controlling the backlight emission brightness of each of the blocks based on a determination result in the determination step, wherein
• in the determination step, when a block corresponding to an object region, which is a region of a predetermined object in an image based on an input image signal, is not included in a predetermined number of blocks centered around a determination-target block, determination is made that the determination-target block is a block which satisfies the predetermined condition, and wherein
• in the control step, a backlight emission brightness of a block corresponding to the object region is set to a first level,
• a backlight emission brightness of a block which satisfies the predetermined condition among the blocks corresponding to the background region is set to a second level that is lower than the first level, and
• a backlight emission brightness of a block which does not satisfy the predetermined condition among the blocks corresponding to the background region is set to a third level that is higher than the second level and not higher than the first level.
