An image formation apparatus (1000) comprises shape data memory means (109) for storing shape data of obstacles, etc., position data specifying means (101) for specifying position data of an object, overlap judgement means (108, 101) for judging whether or not an article is on a line between the view point and the object and observed from the view point, on the basis of the shape data and the position data, and image formation means (110, 112) for forming a virtual image obtained by applying predetermined transmission processing (mesh processing, translucent processing, etc.) to the article when the article is judged as being under the overlap state. Overlap judgement is accurately carried out by using a vector extending from the view point to the object and a vector extending from the obstacle to the object, and the object concealed by the article can be appropriately displayed by the transmission processing such as the mesh processing. |
