Abstract

A thumbnail image generating unit generates thumbnail images from a plurality of images having a sequential relation. A thumbnail image displaying unit displays the thumbnail images generated according to the sequential relation. A thumbnail image designating unit receives a designation of a thumbnail image from among the thumbnail images. An enlarging unit generates an enlarged image of a designated thumbnail image. An enlarged image displaying unit displays the enlarged image. A forward-advance designating unit designates a forward advance of the enlarged image displayed by the enlarged image displaying unit according to the sequential relation.

4. The information display system according to claim 1, wherein the enlarging unit generates an enlarged image of another thumbnail image with a smaller image size than an enlarged image belonging to a same classification as a classification of the designated thumbnail image and a classification similar to the classification of the designated thumbnail image based on the classification information.

5. The information display system according to claim 1, further comprising:

a magnification specifying unit that receives a specification of a display magnification of the thumbnail list view, wherein

the thumbnail image generating unit generates the thumbnail image by at least one of changing size and resolution based on the display magnification.

6. The information display system according to claim 1, wherein

the server device is connected to the client device via an external communication path, the server device including an image database that stores therein the images and the thumbnail images, and wherein

the client device stores encoded data of the images and management information stating which portion of the encoded data is stored and which portion of the encoded data is not stored, generates information on the encoded data that is not stored based on the management information, and transmits a request for transmission of the images including the information on the encoded data, and

the server device receiving the request for transmission transmits the encoded data based on the information on the encoded data included in the request for transmission to the client device.

14. The information display system according to claim 1, further comprising:

a scrolling unit configured to scroll the thumbnail list view in at least one of a horizontal and a vertical direction.

7. A method of displaying information in an information display system, the method comprising:

thumbnail image generating including, generating thumbnail images in a thumbnail list view from a plurality of images having a sequential relation, and generating thumbnail images according to the thumbnail image displaying unit determining;

thumbnail image displaying including displaying the thumbnail images a first size generated in the thumbnail list view according to the sequential relation;

thumbnail image designating including receiving a designation of a thumbnail image from among the thumbnail images;

enlarging the thumbnail images including generating an enlarged image of a designated thumbnail image of a second size larger than the first size from the thumbnail list view, and generating enlarged images of thumbnail images from the thumbnail list view positioned before and after the enlarged designated thumbnail image, based on the sequential relation, having a size smaller than a size of the enlarged designated thumbnail image and larger than the first size;

enlarged image displaying including, displaying a plurality of fully viewable enlarged thumbnail images from among the enlarged designated thumbnail image and the enlarged thumbnail images positioned before and after the designated thumbnail image according to the sequential relation;

forward-advance designating including designating a forward advance of the enlarged image displayed at the enlarged image displaying unit according to the sequential relation; and

caching, by a client device, encoded data related to a thumbnail list view of the generated thumbnail images, the client device being configured to receive, from a server device, when the enlarged images are to be displayed, additional encoded data of the enlarged images to be displayed on a display of the client device; and

a classifying unit that classifies the thumbnail images based on pieces of classification information of the images obtained from outside, wherein the thumbnail image displaying unit displays the thumbnail images in such a manner that classifications of the thumbnail images can be identified, wherein the thumbnail image designating further includes selecting a thumbnail image that is required to be enlarged as a result of a designation of the forward advance according to the sequential relation at the forward-advance designating as the designated thumbnail image, and wherein the forward-advance designating unit assigns a longer display time when displaying an enlarged image belonging to a same classification as a classification of the designated thumbnail image, than when displaying an enlarged image belonging to a different classification than the classification of the designated thumbnail image based on the classification information.

8. The method according to claim 7, further comprising:
