PROBLEM TO BE SOLVED: To provide a pseudo multiport memory device capable of realizing an enhanced transfer method to a reference memory under the condition where all reference areas are stored into a shared large capacity pseudo multiport memory.;SOLUTION: A two-dimensional virtual address generating means 120 generates a two-dimensional virtual address from two-dimensional logic addresses consisting of horizontal logic addresses and vertical logic addresses. A virtual one-dimensional address generating means 130 generates vertical one-dimensional addresses assigned to a 1-port memory in the unit of pixels on the basis of the two-dimensional virtual addresses, a representative real address generating means 140 generates a representative real addresses, a representative real bank number generating means 150 generates a representative real bank number, and a real address generating means 160 generates a real address given to the 1-port memory. A pixel rearrangement means 200 receives and rearranges pixels outputted from each 1-port memory, and an output timing adjustment means 300 adjusts the output timing of the rearranged pixels and outputs the rearranged pixels.;COPYRIGHT: (C)2005,JPO&NCIPI
