Information processing apparatus and non-transitory computer readable medium

1. An information processing apparatus comprising:

a display panel and a processor coupled to the display panel, the processor is configured to

obtain information represented by each of a plurality of thumbnails;

for each thumbnail of the plurality of thumbnails, detect a proportion of an image included in the thumbnail to a total size of the thumbnail;

individually determine a size of each of the plurality of thumbnails based on the detected proportion of each respective thumbnail; and

perform control so that the plurality of thumbnails are displayed on the display panel in a size greater than or equal to the determined size according to the proportion.

2. The information processing apparatus according to claim 1 , wherein the size of each of the thumbnails to be displayed in the determined size or greater is set in accordance with the content of a corresponding thumbnail and a size and a resolution of a screen for displaying the plurality of thumbnails.

3. The information processing apparatus according to claim 2 ,

wherein the processor performs control so that, as a ratio of the number of thumbnails that are found to have the proportion greater than or equal to a threshold to a total number of the plurality of thumbnails is increased, the size of each of the thumbnails to be displayed in the size greater than or equal to the determined size is decreased.

4. The information processing apparatus according to claim 3 , wherein the processor performs control so that the size of each of the thumbnails adjusted by using the proportion will further be adjusted based on visual characteristics of characters included in a corresponding thumbnail.

5. The information processing apparatus according to claim 4 , wherein, if a difference in a color distribution of the characters between adjacent thumbnails is greater than a predetermined threshold, the processor performs control so that the size of each of the thumbnails to be displayed in the size greater than or equal to the determined size is decreased to be smaller than the size of a corresponding thumbnail that was adjusted using the proportion.

6. The information processing apparatus according to claim 4 , wherein, if a degree of similarity concerning an arrangement of the characters between adjacent thumbnails is smaller than a predetermined degree of similarity, the processor performs control so that the size of each of the thumbnails to be displayed in the size greater than or equal to the determined size is decreased to be smaller than the size of a corresponding thumbnail that was adjusted using the proportion.

7. The information processing apparatus according to claim 6 , wherein, to calculate the degree of similarity concerning the arrangement of the characters, the processor uses at least one of a thickness, a size, and a type of the characters.

8. The information processing apparatus according to claim 4 , wherein, if a difference in a distribution of blanks between adjacent thumbnails is greater than a predetermined threshold, wherein the blanks are included in a thumbnail, the processor performs control so that the size of each of the thumbnails to be displayed in the size greater than or equal to the determined size is decreased to be smaller than the size of a corresponding thumbnail that was adjusted using the proportion.

9. The information processing apparatus according to claim 3 , wherein the sizes of the thumbnails are individually adjusted and displayed in the size greater than or equal to the determined size, and the processor performs control so that, among the adjusted thumbnails, sizes of thumbnails displayed in the same row along a horizontal side of a page will be uniform.

10. The information processing apparatus according to claim 9 , wherein the processor performs control so that the thumbnails displayed in the same row of the page are enlarged up to a size of the largest thumbnail displayed in the same row.

11. The information processing apparatus according to claim 9 , wherein the processor performs control so that a vertical side of the thumbnails intersecting a horizontal side of the thumbnails displayed in a final row of the page is further enlarged to minimize a blank produced under the final row.

12. The information processing apparatus according to claim 1 ,

wherein the processor is further configured to receive an instruction to enlarge the size of a thumbnail in accordance with an amount by which an indicator is moved,

wherein the processor performs control so that the size of each of the plurality of thumbnails is displayed in the size greater than or equal to the determined size in accordance with the instruction received by the processor and the plurality of thumbnails displayed in the size greater than or equal to the determined size.

13. The information processing apparatus according to claim 12 , wherein the processor performs control so that the thumbnails displayed in accordance with the instruction will not be displayed on a screen for displaying the plurality of thumbnails until the thumbnails are enlarged to such a degree by which it is not possible to dispose the thumbnails within an existing page without causing the thumbnails to overlap each other unless another page is added.

14. A non-transitory computer readable medium storing a program causing a computer to execute a process, the process comprising:

obtaining information represented by each of a plurality of thumbnails;

for each thumbnail of the plurality of thumbnails, detecting a proportion of an image included in the thumbnail to a total size of the thumbnail;

individually determining a size of each of the plurality of thumbnails based on the detected proportion of each respect thumbnail; and

performing control so that the plurality of thumbnails are displayed in a size greater than or equal to the determined size according to the proportion.
