Beschreibung
Zusammenfassung:	A luminance correcting apparatus has a sensor for detecting luminances of reflected lights of projected lights individually in each of at least two colors which are reflected from a screen, a first memory for storing information representing luminances of the reflected lights in the respective colors which are detected by the sensor, a second memory for storing information representing predetermined reference luminances of the reflected lights in the respective colors, and a luminance correcting data generator for generating luminance correcting data by comparing the information stored in the first memory and the information stored in the second memory.
