Beschreibung
Zusammenfassung:	A projection apparatus projects an image on a screen based on input data including information on absolute luminance. The projection apparatus includes: a peak luminance value acquisition unit configured to acquire a peak luminance value on the screen when the projection apparatus projects an image on the screen at a maximum output gradation value; a reference luminance value setting unit configured to set a reference luminance value to be higher than the peak luminance value; a relation information setting unit configured to set, based on the reference and peak luminance values, relation information indicating a relation between an output gradation value and a light output value for displaying an output image; an output gradation value setting unit configured to set an output gradation value based on the input data and the relation information; and an output control unit configured to output an image based on the output gradation value.
