Zusammenfassung:An image display apparatus includes: a light-emitting unit, a light emission amount of which is variably controllable; a display unit configured to display an image by modulating, according to image data, light emitted from the light-emitting unit; and a control unit configured to control the light emission amount of the light-emitting unit according to a maximum and a minimum of a pixel value in a frame. The control unit maximizes the light emission amount of the light-emitting unit irrespective of the maximum when the minimum is larger than a first threshold.
