Abstract

An information processing device, separate from an image processing apparatus, which controls the image processing apparatus and includes a display unit, a volatile memory store image data, and a nonvolatile memory. The information processing device also includes an image data acquisition unit that acquires image data processed by the image processing apparatus page by page, an image data storage processor that compares the image data acquired by the image data acquisition unit for each page with the image data stored in the volatile memory and to store the image data in either the volatile memory or the nonvolatile memory based on comparison, a display image generator that generates a display image to be displayed on the display unit based on the image data for each page stored in either the volatile memory or the nonvolatile memory, and a display image output controller that displays the display image generated by the display image generator on the display unit.

Claims

1. An information processing device that is separate from an image processing apparatus and which controls operation of the image processing apparatus, comprising:

a volatile memory to store image data;

a nonvolatile memory;

a display;

an image data acquisition unit to acquire image data processed by the image processing apparatus page by page;

an image data storage processor to compare the image data acquired by the image data acquisition unit for each page with the image data stored in the volatile memory and to store the image data acquired by the image data acquisition unit for each page in either the volatile memory or the nonvolatile memory based on comparison;

a display image generator to generate a display image to be displayed on the display unit based on the image data for each page stored in either the volatile memory or the nonvolatile memory; and

a display image output controller to display the display image generated by the display image generator on the display unit.

2. The information processing device according to claim 1, wherein the image data storage processor calculates total size of the image data acquired by the image data acquisition unit for each page and size of image data already stored in the volatile memory and stores the acquired image data and image data for remaining pages acquired subsequently in the nonvolatile memory if the calculated total size exceeds a predetermined threshold value.

3. The information processing device according to claim 1, wherein the image data storage processor starts storing the image data acquired by the image data acquisition unit for each page in the volatile memory and stores the image data that was partially stored in the volatile memory and the remaining image data in the nonvolatile memory if the total size of the image data stored in the volatile memory exceeds the predefined threshold value during the storing process.

4. The information processing device according to claim 1, further comprising a display image storage processor to store the display image generated by the display image generator in one of the memories that stores the image data for the page corresponding to the display image.

5. The information processing device according to claim 4, wherein the display image output controller includes:

a display area detector to detect an area to be displayed on the display unit in a screen to be displayed on the display unit, in which a layout position of the display image that should be displayed on the display unit is set; and

an image drawing controller to draw the display image of the page whose layout position is set within the detected area and display the drawn display image on the display unit,

wherein the image storage processor specifies the display image of a page that should be stored in the volatile memory among the display images stored in the nonvolatile memory, stores the specified display image in the volatile memory, and deletes the display image for another page in the volatile memory if the display image for the other page is stored in both the volatile memory and the nonvolatile memory, and the image drawing controller acquires the display image stored in the volatile memory and draws the display image for the page whose layout position is set in the detected area.

6. The information processing device according to claim 5, wherein the display image storage processor determines an area where the display image is specified as the display image for the target page that should be stored in the volatile memory in accordance with user operation on the screen to be displayed and specifies the display image for the page whose layout position is set within the determined area as the display image that should be stored in the volatile memory.

7. The information processing device according to claim 6, wherein the display image storage processor stores the determined area in the nonvolatile storage area associated with the user who performed the user operation and specifies the display image for the page whose layout position is set within the stored area associated with the user who performs user operation on another screen to be displayed as the display image for the target page in specifying the display image for the target page that should be stored in the volatile memory among the display images whose layout positions are set in the other screen to be displayed.

8. An image processing system comprising:

an image processing apparatus; and

the information processing device of claim 1.

9. A method of controlling an information processing device that is separate from an image processing apparatus and which controls operation of the image processing apparatus and includes a display unit, volatile memory, and nonvolatile memory, comprising the steps of:

acquiring image data processed by the image processing apparatus for each page;

comparing the image data acquired by the image data acquisition unit for each page with image data already stored in the volatile memory to determine whether to store the image data acquired by the image data acquisition unit for each page in the volatile memory or the nonvolatile memory;

generating a display image to be displayed on the display unit based on the image data for each page stored in either the volatile memory or the nonvolatile memory; and

displaying the display image generated by the display image generator on the display unit.

10. A non-transitory, computer-readable recording medium storing a program that, when executed by a computer, causes a processor to implement a method of controlling an information processing device that is separate from an image processing apparatus and which controls operation of the image processing apparatus and includes a display unit, volatile memory, and nonvolatile memory,

the method comprising the steps of:

acquiring image data processed by the image processing apparatus for each page;

comparing the image data acquired by the image data acquisition unit for each page with image data already stored in the volatile memory to determine whether to store the image data acquired by the image data acquisition unit for each page in the volatile memory or the nonvolatile memory;

generating a display image to be displayed on the display unit based on the image data for each page stored in either the volatile memory or the nonvolatile memory; and

displaying the display image generated by the display image generator on the display unit.
