ABSTRACT:
A biocular image display apparatus in which the observer's left and right visual lines intersect at a position where the image as observed appears to be natural to the observer even in a corner of the image field, thereby enabling the observer to make observation with ease and without feeling incongruous even at a wide field angle. The apparatus has left and right display surfaces and left and right optical systems associated with the display surfaces, respectively, wherein enlarged images of the left and right display surfaces are observed through the left and right optical systems. The apparatus has a diopter setting mechanism (11), an interpupillary distance setting mechanism (12), and a vergence mechanism (13) that tilts the left and right optical systems, together with the left and right display surfaces, respectively, as one unit so that the optical axes of the left and right optical systems form a predetermined angle according to the set diopter and interpupillary distance values. The apparatus further has image distorting devices (14 and 15) whereby the display position of any display point on each display surface is changed to a position determined by the coordinates of the display point on the display surface, the diopter value set by the diopter setting mechanism (11), and the interpupillary distance value set by the interpupillary distance setting mechanism (12).
