Abstract
A liquid crystal display apparatus includes: a liquid crystal panel; an input interface for inputting data of a first image; a backlight module; and at least one memory and at least one processor which function as: an estimating unit configured to estimate brightness of light to be irradiated from the backlight module to the liquid crystal panel; a correcting unit configured to correct the first image to a second image based on the brightness estimated by the estimating unit, a contrast of the liquid crystal panel, and a target contrast so that a brightness error with respect to a display brightness in a case where the first image is displayed with the target contrast is suppressed; and a control unit configured to control transmittance of the liquid crystal panel based on data of the second image.
