Abstract:
1. An information processing device that is separate from an image processing apparatus and which controls operation of the image processing apparatus, the image processing device comprising: a volatile memory that stores image data; a nonvolatile memory; a display; an image data acquisition circuit that acquires image data processed by the image processing apparatus page by page; an image data storage processing circuit that compares the image data acquired by the image data acquisition circuit for each page with the image data stored in the volatile memory and stores the image data acquired by the image data acquisition circuit for each page in either the volatile memory or the nonvolatile memory based on comparison; a display image generating circuit that generates a display image to be displayed on the display based on the image data for each page stored in either the volatile memory or the nonvolatile memory; a display image output controlling circuit that controls the display to display the display image generated by the display image generator; and a display image storage processing circuit that stores the display image generated by the display image generating circuit in the memory that stores the image data for the page corresponding to the display image, wherein the display image output controlling circuit includes: a display area detecting circuit that detects an area of a screen to be displayed on the display in which a layout position of the display image that should be displayed on the display is set, and an image drawing controlling circuit that draws the display image of the page whose layout position is set within the detected area and controls the display to display the drawn display image, the image data storage processing circuit is configured to:
