Abstract

A storage unit is configured to store a document to be displayed in a predetermined display area on a display. An instruction acknowledging unit is configured to receive a scroll instruction signal for scrolling the document displayed in the display area. A range identifying unit is configured to identify a previously displayed block displayed in the display area before the scrolling operation and a subsequently displayed block displayed in the display area as updated by the scrolling operation. A delay control unit is configured to cause the previously displayed block to be scrolled in the display area by the predetermined amount of movement and displayed accordingly, and causing the subsequently displayed block to be scrolled and displayed accordingly with a delay from the previously displayed block.

Claims

1. A scroll display program embedded in a recording medium, comprising:

a storage module configured to store in a memory a document to be displayed in a predetermined display area on a display;

an instruction acknowledging module configured to receive a scroll instruction signal for scrolling the document displayed in the display area;

a range identifying module configured to refer to the document in the memory and identify, in according with a predetermined amount of movement, a previously displayed block displayed in the display area before the scrolling operation and a subsequently displayed block displayed in the display area as updated by the scrolling operation; and

a delay control module configured to output an image signal to the display, the image signal causing the previously displayed block to be scrolled in the display area by the predetermined amount of movement and displayed accordingly, and causing the subsequently displayed block to be scrolled and displayed accordingly with a delay from the previously displayed block.

2. The scroll display program according to claim 1,

wherein the delay control module causes the previously displayed block and the subsequently displayed block to be moved in the display area while the document is being scrolled, creating a spacing larger than a line spacing created when the document is displayed in a static manner.

3. The scroll display program according to claim 2,

wherein the delay control module controls the moving speeds of the previously displayed block and the subsequently displayed block such that the previously displayed block and the subsequently displayed block are displayed so as to create, when the scrolling operation is completed, a spacing identical to the line spacing created when the document is displayed in a static manner.

6. The scroll display program according to claim 1,

wherein the delay control module delays the timing of starting scrolling the subsequently displayed block with respect to the timing of starting scrolling the previously displayed block.

7. The scroll display program according to claim 1,

wherein the delay control module controls the moving speeds so that the previously displayed block and the subsequently displayed block become stationary substantially at the same time when the scrolling operation is completed.

8. The scroll display program according to claim 1,

wherein the range identifying module identifies the previously displayed block and the subsequently displayed block in the document based on the predetermined amount of movement.

9. The scroll display program according to claim 8,

wherein, when a part of the last line of the previously displayed block is displayed in the display area, the range identifying module identifies the subsequently displayed block, placing the last line at the head.

10. The scroll display program according to claim 1,

wherein, when a part of an image is included in the subsequently displayed block, the range identifying module extends the range of the subsequently displayed block so as to include the entirety of the image irrespective of the predetermined amount of movement.

11. The scroll display program according to claim 1,

wherein, when a part of an image is included in the subsequently displayed block, the range identifying module reduces the range of the subsequently displayed block so that the block immediately follows the image irrespective of the predetermined amount of movement.

12. A computer readable recording medium that stores the scroll display program according to claim 1.

4. The scroll display program according to claim 4,

wherein the delay control module configures the moving speed of the subsequently displayed block to be lower than the moving speed of the previously displayed block at least when the scrolling operation is started.

5. The scroll display program according to claim 4,

wherein the delay control module configures the moving speed of the subsequently displayed block to be higher than the moving speed of the previously displayed block when the scrolling operation is completed.

13. A scroll display device, comprising:

a storage unit configured to store a document to be displayed in a predetermined display area on a display;

an instruction acknowledging unit configured to receive a scroll instruction signal for scrolling the document displayed in the display area;

a range identifying module configured to refer to the document in the memory and identify, in accordance with a predetermined amount of movement, a previously displayed block displayed in the display area before the scrolling operation and a subsequently displayed block displayed in the display area as updated by the scrolling operation; and

a delay control module configured to cause the previously displayed block to be scrolled in the display area by the predetermined amount of movement and displayed accordingly, and causing the subsequently displayed block to be scrolled and displayed accordingly with a delay from the previously displayed block.

14. An electronic terminal provided with the scroll display device according to claim 13.

15. A scroll display method comprising:

storing in a memory a document to be displayed in a predetermined display area on a display;

receiving a scroll instruction signal for scrolling the document displayed in the display area;

referring to the document in the memory and identifying, in accordance with a predetermined amount of movement, a previously displayed block displayed in the display area before the scrolling operation and a subsequently displayed block displayed in the display area as updated by the scrolling operation; and

outputting an image signal to the display, the image signal causing the previously displayed block to be scrolled in the display area by the predetermined amount of movement and displayed accordingly, and causing the subsequently displayed block to be scrolled and displayed accordingly with a delay from the previously displayed block.
