IMAGE PROJECTION APPARATUS

摘要

An image projection apparatus includes a light source, a color wheel, a controller. The controller controls, in a first mode, electric power supplied to the light source at a timing of a first color filter being irradiated with light from the light source 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. Furthermore, the controller controls, in a second mode, the electric power supplied to the light source at the timing of the first color filter being irradiated with the light from the light source 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.

主权项

1. 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; 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 in a first mode, the controller controls electric power that is supplied to the light source at a timing at which a first color filter 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 a timing at which a second color filter corresponding to a color having lower visibility than a color of the first color filter is irradiated with the light from the light source, and in a second mode, the controller controls the electric power that is supplied to the light source at the timing at which the first color filter 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 timing at which the second color filter is irradiated with the light from the light source.
