Abstract:
A superpositional image display type information input/output device comprising:(a) an image generator unit generating a first image for display in superposition and a second image to be superposed from a given image; and (b) a superpositional image display unit providing a first display image plane of the first image for display in superposition and a second display image plane of the second image to be superposed in separated levels from each other in a superposed state such that the first image for display in superposition will appear to be floated on or recessed from the second display image plane of the second image to be superposed, wherein said image generator unit comprises: a mask pattern generating module generating a mask pattern for the first image for display in superposition; and an image generating module generating the second image to be superposed from said mask pattern and said given image.
