However, methods have been proposed in which the hue of the illumination light from this illumination means is changed manually (adjusting the hue setting volume) or by a preset hue change program. In some cases, the lighting around the location gives the viewer a sense of presence similar to that of a large screen.For example, if the image being projected on a TV receiver is ``Blue Sky If the ceiling lighting is a blue-ish color, and if the sunset is in the sky, then the ceiling lighting is a red-ish color, so that even if the TV receiver screen is small, the image appears to be spreading across the ceiling. You can get a sense of realism comparable to that of a large screen, and by adding sound effects you can easily create a simple home theater.
