Abstract
An image observing apparatus is arranged to observe outside information from the outside and a display image displayed on an image display device via an optical combiner and via an eyepiece lens superimposed. The outside information and the display image are imaged so as to be superimposed on a surface of a spatial modulator having a two-dimensional pixel structure. Part or all of the outside information and display image is selected on an area basis by the spatial modulator. The outside information and image information thus selected is observed through the eyepiece lens.
