To provide an image display apparatus capable of allowing a viewer to see a clear image even if the position of a screen is changed, and an image distortion correction method of the image display apparatus.
The image display apparatus includes a projector 2 receiving an image signal and projecting image light and the screen 1 including a projection plane of arbitrary shape. The projector 2 and the screen 1 are connected with link mechanisms 3a to 3c and link mechanisms 3b and 3d. The relative position and posture between the projector 2 and the screen 1 are automatically or manually changeable. The relative position and posture between the projector 2 and the screen 1 are measured, and correction parameters for correcting distortion of image light projected from the projector 2 onto the screen 1 are calculated from the preset viewing position of the viewer and the shape of the projection plane of the projector 2. On the basis of the calculated correction parameters, the image signal input into the projector 2 is subjected to distortion correction processing.
