Abstract

First type icon data containing one icon image per content item and second type icon data containing a plurality of icon images per content item are received and temporarily stored in a temporary storage unit. Among the icon data temporarily stored in the temporary storage unit, an icon image is read from each of one or a plurality of icon data items and displayed. In so doing, regarding the second type icon data among the icon data whose icon images are being displayed, a plurality of corresponding icon images are sequentially displayed by being sequentially read out of the temporary storage unit.

Claims

1. A data browsing apparatus comprising:

a temporary storage unit configured to receive and temporarily store first type icon data containing one icon image per content item and second type icon data containing a plurality of icon images per content item;

a first reading unit configured to read one icon image per content item from the icon data stored in said temporary storage unit;

an icon display unit configured to display the icon images read by said first reading unit;

a second reading unit configured to sequentially read, from said temporary storage unit, a plurality of icon images of the second type icon data among the icon data whose icon images are being displayed by said icon display unit and;

a sequential display unit configured to display the icon images read by said second reading unit, at a display position of the second type icon data by switching from one icon image to another.

2. The data browsing apparatus according to claim 1, wherein from when said icon display unit completes the display until a new display range update instruction is input, said second reading unit and the sequential display unit repeat processing the second type icon data temporarily stored in said temporary storage unit.

3. The data browsing apparatus according to claim 1, wherein if a focused icon image among the displayed icon images is from the second type icon data, said second reading unit and said sequential display unit process the focused icon data.

7. The data browsing apparatus according to claim 1, wherein content corresponding to the first type icon data is still image data and content corresponding to the second type icon data is moving image data.

8. The data browsing apparatus according to claim 1, wherein content corresponding to the first type icon data is single-page document data and content corresponding to the second type icon data is multi-page document data.

9. The data browsing apparatus according to claim 1, wherein said second reading unit and said sequential display unit read and display the plurality of icon images at a frame rate of moving image data.

4. A data browsing apparatus comprising:

a temporary storage unit configured to receive and temporarily store first type icon data containing one icon image per content item, second type icon data containing a plurality of icon images per content item, and attribute data of the icon data;

an attribute data reading unit configured to sequentially read the attribute data stored in said temporary storage unit;

a first reading unit configured to read, when the attribute data read by said attribute data reading unit indicates the first type, an icon image contained in the icon data corresponding to the attribute data out of said temporary storage unit;

an icon display unit configured to display the icon image read by said first reading unit;

a second reading unit configured to sequentially read, when the attribute data read by said attribute data reading unit indicates the second type, a plurality of icon images contained in the icon data corresponding to the attribute data out of said temporary storage unit; and

a sequential display unit configured to sequentially display the icon images read by said second reading unit.

5. The data browsing apparatus according to claim 4, wherein from when said display unit finishes displaying the one or plurality of icon data items to be displayed until a new display range update instruction is input, said second reading unit and said sequential display unit repeat processing the second type icon data among the one or plurality of icon data items to be displayed.

6. The data browsing apparatus according to claim 4, wherein if a focused icon image among the displayed icon images is the second type icon data, said second reading unit and said sequential display unit sequentially display a plurality of icon images from the focused icon data.

10. A control method for a data browsing apparatus, comprising:

a temporary storage step of receiving and temporarily storing first type icon data containing one icon image per content item and second type icon data containing a plurality of icon images per content item in a temporary storage unit;

a first reading step of reading one icon image per content item from the icon data stored in the temporary storage unit;

an icon display step of displaying on a screen the icon images read in said first reading step;

a second reading step of sequentially reading, from the temporary storage unit, a plurality of icon images of the second type icon data among the icon data whose icon images are being displayed by said icon display step and;

a sequential display step of displaying the icon images read in said second reading step, at a display position of the second type icon data by switching from one icon image to another.

12. A computer-readable storage medium storing a computer program which makes a computer execute the steps of the control method for a data browsing apparatus according to claim 10.

11. A control method for a data browsing apparatus, comprising:

a temporary storage step of receiving and temporarily storing first type icon data containing one icon image per content item, second type icon data containing a plurality of icon images per content item, and attribute data of the icon data in a temporary storage unit;

an attribute data reading step of sequentially reading the attribute data stored in the temporary storage unit;

a first reading step of reading, when the attribute data read in said attribute data reading step indicates the first type, an icon image contained in the icon data corresponding to the attribute data out of the temporary storage unit;

an icon display step of displaying on a screen the icon image read in said first reading step;

a second reading step of sequentially reading, when the attribute data read in said attribute data reading step indicates the second type, a plurality of icon images contained in the icon data corresponding to the attribute data out of the temporary storage unit; and

a sequential display step of sequentially displaying the icon images on the screen read in said second reading step.

13. A computer-readable storage medium storing a computer program which makes a computer execute the steps of the control method for a data browsing apparatus according to claim 11.
