Abstract

An electronic paper system that uses an electronic paper comprising a display section displaying an image in a no-power supply state, which includes: a retention unit that stores a display image in association with at least one of the document data and the electronic paper, the display image being generated from document data and displayed on the display section of the electronic paper; and an output unit that outputs the display image stored in the retention unit.

Claims

1. An electronic paper system that uses an electronic paper comprising a display section displaying an image in a no-power supply state, which comprises:

a retention unit that stores a display image in association with at least one of the document data and the electronic paper, the display image being generated from document data and displayed on the display section of the electronic paper; and

an output unit that outputs the display image stored in the retention unit.

2. The electronic paper system as claimed in claim 1,

wherein

the output unit outputs the display image associated with at least one of the document data to be processed and the electronic paper to be processed, and

the electronic paper system comprises:

an image generation unit that generates a new display image based on the display image outputted from the output unit; and

an image write unit that writes the new display image to the electronic paper to be processed, and that displays the new display image.

3. The electronic paper system as claimed in claim 2,

wherein

the electronic paper comprises:

a storage section that stores information of at least one of association information and identification information of the electronic paper, the association information associating the electronic paper with the document data,

the electronic paper system comprises;

a determination unit that determines the display image based on the information read from the storage section, the display image being associated with at least one of the document data to be processed and the electronic paper to be processed, and

the output unit that outputs the display image determined by the determination unit.

4. The electronic paper system as claimed in claim 2,

wherein

the retention unit stores the display image in association with the document data,

the output unit outputs the display image associated with the document data to be processed, and

the new display image is a comparison image of a reduced image generated from the document data to be processed and a reduced image of the display image.

5. The electronic paper system as claimed in claim 2,

wherein

the retention unit stores the display image in association with the document data,

the output unit outputs the display image associated with the document data to be processed, and

the new display image is an image combined an image explaining the state of the document data to be processed and a reduced image of the display image output by the output unit.

6. An electronic paper system comprising:

a document management apparatus that stores document data;

a log management apparatus; and

an information processing apparatus that generates a display image from the document data stored in the document management apparatus, the display image being displayed on electronic paper comprising a display section holding display of an image in a no-power supply state,

wherein

the log management apparatus comprises;

a retention unit that stores the display image in association with at least one of the document data and the electronic paper, and

the information processing apparatus comprises;

an output unit that acquires the display image from the retention unit, the display image being associated with at least one of the document data to be processed and the electronic paper to be processed, and that outputs the display image;

an image generation unit that generates a new display image based on the display image output by the output unit; and

an image write unit that writes the new display image to the electronic paper to be processed, and that displays the new display image.

7. An electronic paper system comprising:

a document management apparatus that stores document data; and

an information processing apparatus that generates a display image from the document data stored in the document management apparatus, the display image being displayed on electronic paper comprising a display section holding display of an image in a no-power supply state,

wherein

the document management apparatus comprises;

a retention unit that stores the display image in association with at least one of the document data and the electronic paper, and

the information processing apparatus comprises;

an output unit that acquires the display image from the retention unit, the display image being associated with at least one of the document data to be processed and the electronic paper to be processed, and that outputs the display image;

an image generation unit that generates a new display image based on the display image output by the output unit; and

an image write unit that writes the new display image to the electronic paper to be processed, and that displays the new display image.

8. An electronic paper system comprising:

a document management apparatus that stores document data; and

an information processing apparatus that generates a display image from the document data stored in the document management apparatus, the display image being displayed on electronic paper comprising a display section holding display of an image in a no-power supply state,

wherein

the log management apparatus comprises;

an retention unit that stores a display image generated from document data and displayed on the display section of the electronic paper in association with at least one of the document data and the electronic paper;
