Abstract
A display method and apparatus for displaying information by projecting a light onto an external projection plane is capable of detecting a deviation amount of a displayed image projected on the projection plane with respect to the display apparatus. Output image data is changed based on the detected deviation amount to offset a distortion of the displayed image, which is displayed using the changed output image data.
