PROBLEM TO BE SOLVED: To efficiently read out and output image data compared to a conventional case when image data stored in a plurality of storage devices is output prioritizing the productivity over image quality.SOLUTION: When having acquired image data containing at least one plane image, a control device 7 determines as a division size the size of an image for one line of the plane image contained in the image data and divides the plane image by the division size. Then, a writing control section 25 differentiates the lines obtained by dividing the plane image, into even-numbered lines and odd-numbered lines, and separately writes the even-numbered lines and the odd-numbered lines in a plurality of storage devices 11, respectively. When reading out the plane image, a reading control section 31 selectively reads out either one of the even-numbered lines and the odd-numbered lines divisionally written in the plurality of storage devices 11, respectively.SELECTED DRAWING: Figure 2 |
