a stereoscopic display device in accordance with the present invention utilizes a display screen for displaying images for right and left eyes . the display device comprises : a drawing circuit which generates image data for the right and left eyes according to view point data including view point position and light of sight directions , and object data to be displayed ; and image processing unit which determines an attention target object from the plurality of objects to be displayed according at least to the shortness of the distance from the view point position to the object position , modifies the line of sight directions for the images for the right and left eyes according at least to the distance of the attention target object , and provides view point data and object data to the drawing circuit , where the drawing circuit performs perspective conversion based on the modified line of sight directions . if the attention target object comes closer , the line of sight directions corresponding to the right and left screens are modified according to the distance between the object and view point position , and perspective conversion is performed based on the modified line of sight directions , therefore images displayed on the display screen can conform to natural human perception .
