ABSTRACT:
By using a spectral reflectance of a projection plane or color information under a light source, which is stored in wall color storage means4,matrix calculation means5calculates a conversion matrix, and mixing amounts R, G, B of primary colors of an input image are converted into corrected mixing amounts R′, G′, B′, and they are projected by means of a projector. Thereby, even in a case where a wall is colored, correct color reproduction is made in a colorimetric manner.
