PROBLEM TO BE SOLVED: To obtain an image enlargement device capable of enlarging/reducing an image at a low cost. SOLUTION: A reduction interpolation circuit 1 interpolates the reduction of parallel two-phase picture data. A selection/rearrangement circuit 4 selects and rearranges picture data obtained from the circuit 1 and writes the rearranged data in a FIFO memory 2 again as parallel two-phase picture data. A selection/rearrangement circuit 5 selects and rearranges picture data outputted from the memory 2 and outputs the rearranged data as parallel four-phase picture data. An enlargement interpolation circuit 3 interpolates the enlargement of the parallel four-phase picture data and outputs the interpolated data as parallel two-phase picture data. |
