The present invention provides an image display device which detects projection region suitable for performing a display of an image and displays an image on the detected projection region. The present invention provides an image display device which displays an image on a projection surface by projecting light on the projection surface. The image display device includes an aptitude detection part which detects an aptitude as the projection surface, and a projection control part which controls projection light such that the an image to be displayed on the projection surface falls within a predetermined projection region in response to a detection result by the aptitude detection part. For example, the image display device further includes an aptitude value arithmetic operation part which recognizes the projection area as a mass of a plurality of divided regions and detects aptitude values of projection surfaces of the respective divided regions, a projection region determining part which selects one or more divided regions out of the plurality of divided regions as the projection regions based on the aptitude values, and an image processing part which controls projection light such that an image to be projected on the projection surface falls within one or more projection regions. |
