Display apparatus with compensation for brightness-insufficient light source, and control method therefor

摘要

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.

1. A display apparatus comprising:
an input unit configured to input display image data and information relating to a target brightness reference value of the display image data; 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 on the basis of the display image data; a determination unit configured to determine a target brightness for each light source of the plurality of light sources on the basis of a brightness of the display image data in a region corresponding to the respective light source; and a control unit configured to control the emission brightness of each light source based on the target brightness, wherein in a case where a brightness-insufficient light source, for which the target brightness corresponding to the brightness of the display image data in the corresponding region exceeds an upper limit value of the emission brightness, is present among the plurality of light sources, the determination unit adjusts, based on the target brightness reference value, the target brightness of light sources around the brightness-insufficient light source, to a value higher than a value corresponding to the brightness of the display image data in regions corresponding to the light sources around the brightness-insufficient light source.
