Abstract

An information processing apparatus includes a display section, a generation section, a determination section, and a control section. The display section includes a screen. The generation section generates an image of content data including visible data. The determination section determines an area surrounding an area in which the visible data is arranged in the generated image and corresponding to a shape of the screen, as a visible data area. The control section generates, by the generation section, an enlarged image obtained by enlarging the image so that a size of the screen and a size of the visible data area become close to each other, determines, by the determination section, the visible data area in the enlarged image, and extracts the visible data area from the enlarged image to display the visible data area on the screen.

Claims

1. An information processing apparatus, comprising:

a display including a screen;

a generation mechanism that generates an image of content data including visible data;

a determination mechanism that determines an area surrounding an area in which the visible data is arranged in the generated image and corresponding to a shape of the screen, as a visible data area; and

a controller having a processor that controls the mechanism to generate an enlarged image obtained by enlarging the image so that a size of the screen and a size of the visible data area become close to each other, determining, by the determination mechanism, the visible data area in the enlarged image, and extracting the visible data area from the enlarged image to display the visible data area on the screen.

2. The information processing apparatus according to claim 1, further comprising:

a storage device that stores an enlargement ratio used for generating the enlarged image by the generation mechanism,

wherein when the image of the content data is divided into a plurality of pages to be displayed on the screen, the controller stores in the storage device the enlargement ratio used for generating the enlarged image of a previous page and generates, by the generation mechanism, the enlarged image of a next page by using the stored enlargement ratio.

3. The information processing apparatus according to claim 1,

wherein when a difference between the size of the screen and the size of the visible data area is larger than a threshold value, the controller generates, by the generation mechanism, the enlarged image obtained by enlarging the image so that the size of the screen and the size of the visible data area become close to each other, determines, by the determination mechanism, the visible data area in the enlarged image, and extracts the visible data area from the enlarged image to display the visible data area on the screen, and when the difference between the size of the screen and the size of the visible data area is equal to or smaller than the threshold value, the controller extracts the visible data area from the image to display the visible data area on the screen.

4. The information processing apparatus according to claim 1,

wherein the controller causes the generation mechanism to generate, the enlarged image that is enlarged with a center position of the image being fixed.

5. The information processing apparatus according to claim 1,

wherein the controller causes the generation mechanism to generate by the generation means, the enlarged image that is enlarged so that an upper end of the visible data area comes close to an upper end of the screen with a center position of a lateral width of the image being fixed.

6. The information processing apparatus according to claim 1,

wherein the controller causes the generation mechanism to generate the enlarged image that is enlarged so that any end of the visible data area comes close to an end of the screen with a center position of the visible data area being aligned with a center position of the image.

7. The information processing apparatus according to claim 1,

wherein the controller causes the generation mechanism to generate the enlarged image that is enlarged so that an upper end of the visible data area comes close to an upper end of the screen with a center position of a lateral width of the visible data area being aligned with a center position of a lateral width of the image.

8. The information processing apparatus according to claim 4,

wherein the content data is electronic book data.

9. An image enlargement processing method, comprising:

generating an image of content data;

determining an area surrounding an area in which visible data is arranged in an image generated in the generating step and corresponding to a shape of a screen of a display, as a visible data area; and

causing with a processor to generate in the generating step an enlarged image obtained by enlarging the image so that a size of the screen and a size of the visible data area become close to each other, and causing in the determining step to determine the visible data area in the enlarged image, and extracting the visible data area from the enlarged image to display the visible data area on the screen.

10. A non-transitory computer program product having computer readable instructions that when executed by a processor cause a computer to implement components comprising:

means for generating an image of content data including visible data;

means for determining an area surrounding an area in which the visible data is arranged in the generated image and corresponding to a shape of a screen of a display, as a visible data area; and

a control means for generating, by the means for generating, an enlarged image obtained by enlarging the image so that a size of the screen and a size of the visible data area become close to each other, determining, by the means for determining, the visible data area in the enlarged image, and extracting the visible data area from the enlarged image to display the visible data area on the screen.

11. An information processing apparatus, comprising:

a display section including a screen;

a generation section to generate an image of content data including visible data;

a determination section to determine an area surrounding an area in which the visible data is arranged in the generated image and corresponding to a shape of the screen, as a visible data area; and

a control section to generate, by the generation section, an enlarged image obtained by enlarging the image so that a size of the screen and a size of the visible data area become close to each other, determine, by the determination section, the visible data area in the enlarged image, and extract the visible data area from the enlarged image to display the visible data area on the screen.
