Abstract
Provided is a device and a method in which an HDR image of which a setting luminance is higher than the highest allowable luminance of a display unit, can be displayed as a bright image in a bright audiovisual environment. An adjusted luminance for output is calculated by multiplying an output luminance calculated according to an input/output transfer function corresponding to an input HDR image, and a predetermined gain, together, and thus, a display image is generated. An image signal processing unit sets a reference point P to be in a position based on the highest allowable luminance of a display unit, and calculates the adjusted luminance for output by applying a gain function of setting a gain, based on the reference point P, to an input/output transfer function according to the input HDR image, and thus, generates the display image.
