Abstract: A projector includes a measurement unit, a correction parameter generation unit, and an image processing unit. The measurement unit measures a color of an image formed on a projection surface in terms of a plurality of colors constituting an RGB color system and at least one color constituting an XYZ color system. The correction parameter generation unit generates a correction parameter based on a conversion value and a second measurement value of the color, which is measured by the measurement unit among the colors constituting the XYZ color system. The conversion value is obtained by converting a first measurement value of the color in the RGB color system, which is measured by the measurement unit, into the color in the XYZ color system. The image processing unit corrects image light with the correction parameter.
