发明名称 IMAGE PROJECTION APPARATUS
摘要 An image projection apparatus (1) includes a light source (3), a color wheel (4), a controller (103). The controller (103) controls, in a first mode, electric power supplied to the light source (3) at a timing of a first color filter being irradiated with light from the light source (3) to be a value higher than electric power supplied to the light source at a timing of a second color filter corresponding to a color having lower visibility than a color of the first color filter being irradiated with the light from the light source (3). Furthermore, the controller (103) controls, in a second mode, the electric power supplied to the light source (3) at the timing of the first color filter being irradiated with the light from the light source (3) to be a value lower than the electric power supplied to the light source at the timing of the second color filter being irradiated with the light.
