Abstract
A color wheel includes a plural of transmission areas (R, G, B, C, W and Y) on which light from a light source is made incident and which each transmit light of a different wavelength. A detector detects ambient information. A power supplier supplies power to the light source. A controller controls the supply power to be supplied to the light source by the power supplier. The transmission areas (R, G, B, C, W and Y) on which light from the light source is made incident are sequentially changed. When the ambient information satisfies a predetermined condition, the controller changes the supply power in synchrony with the transmission areas (R, G, B, C, W and Y).
