An image display apparatus is disclosed that includes an image projecting unit that projects a projection image on a projection screen, a written image capturing unit that captures a written image of a writing screen that is arranged opposite the projection screen, a written image area extracting unit that extracts a written image area from the captured written image captured by the written image capturing unit, an image compositing unit that composites the written image area extracted by the written image area extracting unit and the projection image projected by the image projecting unit. The written image area extracting unit includes an external light value detecting unit that detects an external light value and an image processing unit that performs an image correction process on the captured written image based on the external light value detected by the external light detecting unit. |
