Abstract
A glass unit such as a binocular or monocular in which an object to be observed is viewed under magnification is made to display a map image, whereby the observer'"'"'s own position can be specified on the map image without an atlas being opened. Based on a self-position data input from a GPS unit (21), a CPU (31) transmits map image information near its own position from a topographic map database (23) to a CG buffer (39) by way of a memory (25). On the other hand, based on the self-position data, a mark or character indicative of its position on the map image is generated by a mark character generating unit (35) so as to be superimposed onto the map image from the CG buffer (39), whereby a composite image thus formed is displayed by an LCD within a housing (10) so as to be viewed within the visual field of the glass unit.
