    摘要: An image displaying apparatus displays a color image with favorable quality on a predetermined surface. A light source unit emits light beams within different wavelength ranges optically modulated by image information. A light combining unit combines light beams from the light source unit into a light beam. A scanning unit scans a scanned surface with the light beam from the light combining unit and forms an image thereon. A controlling unit synchronously controls the scanning unit and the light source unit. A dividing unit divides a light beam into more than one light beam within an arbitrary optical path on light-incident side of the scanning unit. A receiving unit and adjustment unit adjust quantity of light emission of one or more light source units based on the light quantity received by the receiving unit on one of the optical paths divided by the dividing unit.
