Abstract
An image projection apparatus and method for amplifying a quantity of light includes a light source that irradiates a white light. A light amplifying unit amplifies the light quantity of a light having a certain wavelength of the white light, and the light amplifying unit outputs the amplified light. The light amplifying unit is formed of a fluorescent substance that lets the wavelength of the visible light band pass, while absorbing the other wavelengths. The light amplifying unit receives the external wavelength identical to the certain wavelength, thereby amplifying the certain wavelength. Accordingly, the light quantity of monochromatic light of the certain wavelength is amplified, improving the light utilization efficiency. Additionally, hue/saturation/brightness of the color is also improved by moving the intermediate wavelength of the certain wavelength within a predetermined range.
