Abstract
An adjustment image for facilitating adjustment is generated. An image display device according to an embodiment of the invention includes a semiconductor laser, a wheel, an adjustment image generating unit, and a projection unit. The semiconductor laser emits light. The wheel includes a first area and a second area as areas for adjusting color components of the light emitted from the semiconductor laser. The adjustment image generating unit generates an adjustment image in which a first color formed using a section adjacent to a boundary between the first area and the second area and a second color formed not using the section adjacent to the boundary and having color components close to the first color are arranged adjacent to each other. The projection unit projects the adjustment image generated by the adjustment image generating unit.
