A video game apparatus 1 includes: storage block 163a that stores left eye-use and right eye-use images forming each of objects individually in a first aspect where a spaced distance is zero and a second aspect where the spaced distance has a predetermined value; processor 161k that determines whether or not each of the objects to be displayed is capable of being designated; controller 161c that individually reads out, in the second aspect, both images of the object capable of being designated, and otherwise in the first aspect, from the both image storage block, then guides the read out the both images to one displaying storage block to then synthesize the both images with each other there, and thereafter, reads out the synthesized image to a monitor 11 capable of 3D stereoscopic display; and a processer 161m that receives designation to the object displayed in the second aspect.
