An image projection apparatus comprising: a light source that emits light having brightness in accordance with electric power that is supplied; a color wheel that includes a plurality of color filters disposed along a circumferential direction and transmits the light from the light source sequentially from each of the color filters, wherein each of the color filters of the color wheel is part of a first color filter group or a second color filter group, wherein filters of the second color filter group have a lower visibility than filters of the first color filter group; a controller that controls the electric power that is supplied to the light source variably in accordance with a timing at which each of the color filters is irradiated with the light from the light source; and an image forming unit that modulates intensity of the light that has transmitted through the color wheel so as to form an image, wherein the apparatus is operable in a first mode, in which brightness of the image is maximum, and a second mode, in which brightness of the image is minimum; and characterized in that in the first mode, the controller controls electric power that is supplied to the light source at timings at which each filter of the first color filter group is irradiated with the light from the light source to be a value higher than electric power that is supplied to the light source at timings at which each filter of the second color filter group is irradiated with the light from the light source, and in the second mode, the controller controls the electric power that is supplied to the light source at the timings at which each filter of the first color filter group is irradiated with the light from the light source to be a value lower than the electric power that is supplied to the light source at the timings at which each filter of the second color filter is irradiated with the light from the light source. a light source that emits light having brightness in accordance with electric power that is supplied; a color wheel that includes a plurality of color filters disposed along a circumferential direction and transmits the light from the light source sequentially from each of the color filters, wherein each of the color filters of the color wheel is part of a first color filter group or a second color filter group, wherein filters of the second color filter group have a lower visibility than filters of the first color filter group; a controller that controls the electric power that is supplied to the light source variably in accordance with a timing at which each of the color filters is irradiated with the light from the light source; and an image forming unit that modulates intensity of the light that has transmitted through the color wheel so as to form an image, wherein the apparatus is operable in a first mode, in which brightness of the image is maximum, and a second mode, in which brightness of the image is minimum; and characterized in that in the first mode, the controller controls electric power that is supplied to the light source at timings at which each filter of the first color filter group is irradiated with the light from the light source to be a value higher than electric power that is supplied to the light source at timings at which each filter of the second color filter group is irradiated with the light from the light source, and in the second mode, the controller controls the electric power that is supplied to the light source at the timings at which each filter of the first color filter group is irradiated with the light from the light source to be a value lower than the electric power that is supplied to the light source at the timings at which each filter of the second color filter is irradiated with the light from the light source.
