Abstract
This invention relates to an image display apparatus having first image generating means for displaying first image information by a plurality of pixels emitting light, second image generating means for displaying second image information by a plurality of pixels emitting light, the second image information being part of the first image information, visual axis detecting means for detecting an observer's visual axis direction, optical means for combining a first image from the first image generating means and a second image from the second image generating means, moving the second image relative to the first image in conformity with an output signal from the visual axis detecting means and turning it to the observer's pupil, the marginal portion of the second image being made substantially coincident with the boundary between the pixels of the first image when the images are combined, and image display changing means for changing the first image information and the second image information on the basis of the output signal of the visual axis detecting means.
