That is, in the lighting effect step S100, since the effect image G is deformed to match the size of the background area R, it is not necessary to create the effect image in consideration of the size of the background image H. Therefore, the work efficiency is not impaired by creating the effect image G in consideration of the size of the background image H.

Further, in the lighting effect step S100, since the background area R is set so as to surround the arrangement position of the lighting fixture 10, it is not necessary to create the effect image G while considering the arrangement position of the lighting fixture 10 in the background image H. .. Therefore, the work efficiency is not impaired by creating the effect image G in consideration of the arrangement position of the lighting fixture 10 in the background image H.
