Display apparatus and method for controlling same

A display apparatus comprising:

• a light-emitting unit having a plurality of light sources of which emission brightness can be controlled individually;
• a display unit configured to display an image on a screen by modulating light from the light-emitting unit;
• an obtaining unit configured to obtain, for each of the plurality of light sources, a characteristic value representing a brightness of an image to be displayed in an area on the screen corresponding to the light source;
• a first detection unit configured to detect, as a first block, an area in which a predetermined object is displayed, from among a plurality of areas corresponding to the plurality of light sources;
• a second detection unit configured to detect, as a second block, an area in which no moving object is displayed, from among the plurality of areas;
• a correction unit configured to correct a characteristic value which has been obtained for a light source corresponding to a third block, which is an area which has been detected as a first block by the first detection unit and which has been detected as a second block by the second detection unit, on the basis of characteristic values which have been obtained for surrounding light sources;
• and
• a control unit configured to control, for each of the light sources, an emission brightness of the light source to a value based on a characteristic value corresponding to the light source.

A method for controlling a display apparatus that includes:

• a light-emitting unit having a plurality of light sources of which emission brightness can be controlled individually;
• and
• a display unit configured to display an image on a screen by modulating light from the light-emitting unit,
• the method comprising:
• determining, for each of the plurality of light sources, a target brightness based on a brightness of an image to be displayed in an area on the screen corresponding to the light source;
• detecting, as a first block, an area in which a predetermined object is displayed, from among a plurality of areas corresponding to the plurality of light sources;
• detecting, as a second block, an area in which no moving object is displayed, from among the plurality of areas;
• correcting a target brightness of a light source corresponding to a third block, which is an area which has been detected as a first block and which has been detected as a second block, on the basis of target brightnesses of surrounding light sources;
• and
• controlling, for each of the light sources, an emission brightness of the light source to the target brightness.
