ABSTRACT:
An image information processing apparatus includes a cross bar switch circuit receiving first image information which indicates a two-dimensional image and second image information which indicates three-dimensional computer graphics describing a three-dimensional object by approximation using a plurality of polygons, an arbitration circuit controlling a connection of the cross bar switch circuit according to a predetermined rule based on a synchronizing signal which is related to the first image information, and a memory unit having a first memory region and a second memory region which is different from the first memory region. The memory unit is capable of reading information from the second memory region during a time in which image information output from the cross bar switch circuit is written in the first memory region.
