Abstract
An information display apparatus irradiates a transmissive reflection member with light for forming an image so as to make a virtual image of the image visible on the transmissive reflection member. The information display apparatus includes a memory, and a processor coupled to the memory and configured to control, upon a change in depth of a scene position at which to superimpose the virtual image, a degree of change in a part or an entirety of the virtual image to be displayed, differently from a degree of the change in depth.
