Abstract:
A display apparatus includes: a light emitting unit having a plurality of light sources; a display unit; a determination unit configured to determine, for each light source, a target brightness on the basis of a display image data in region corresponding to the light source; and a control unit configured to control the emission brightness of each light source to the target brightness, wherein when a brightness-insufficient light source is present, the determination unit adjusts the target brightness of light sources around the brightness-insufficient light source, to a value higher than a value corresponding to the display image data in regions corresponding to the light sources around the brightness-insufficient light source.
