PROBLEM TO BE SOLVED: To enhance the memory access speed from both a scanner and a plotter when they compete for memory access, without lowering the utilization efficiency when access to a memory shared with the scanner occurs alone, when an image formation apparatus including a scanner and a plotter performs scanner operation.SOLUTION: Reading of output image data from a shared memory 150 to a plotter image transfer device 120 is detected, and when it is detected, the reading image data being inputted from an image input device 220 is divided, and the write acces for writing the reading image data thus divided in the shared memory 150, and the read access for reading the output image data from the shared memory 150 to the plotter image transfer device 120 are controlled. |
