Abstract

A content display device detects a first operation on a displayed content and determine a display magnification ratio based on the operation quantity of the first operation, displays a display image of the content that has been subjected to a first image processing for enlargement or reducing by the display magnification ratio, and, displays a display image of the content that has been subjected to a second image processing when the display magnification ratio falls beyond a first threshold range.

Claims

1. A content display device for displaying content on a display screen, comprising:

a first operation detector configured to detect a first operation on a displayed content;

a first display controller that is configured to determine a display magnification ratio based on the operation quantity of the first operation and display a display image of the content that has been subjected to a first image processing for enlargement or reducing by the display magnification ratio; and

,

a second display controller that is configured to display a display image of the content that has been subjected to a second image processing when the display magnification ratio falls beyond a first threshold range.

2. The content display device according to claim 1, further comprising:

a third display controller that is configured to display a display image of the content that has been subjected to a third image processing when the display magnification ratio falls beyond a second threshold range.

3. The content display device according to claim 1, further comprising a second operation detector configured to detect a second operation, wherein when the second operation has been detected, the display image is output by the first display controller even if the display magnification ratio falls beyond a predetermined threshold range.

4. The content display device according to claim 1, wherein the first operation is a pinch-in operation or a pinch-out operation, and the second display controller displays a display image of the content that has been subjected to a special reducing and displaying process as the second image processing when the display magnification ratio is equal to or lower than the predetermined threshold.

5. The content display device according to claim 4, wherein the special reducing and displaying process outputs a display image by reducing the content and text in the content by different reducing ratios.

6. The content display device according to claim 1, wherein the first operation is a pinch-out operation, and the second display controller displays the display image of the content in full-screen mode as the second image processing when the display magnification ratio has become equal to or higher than the predetermined threshold.

7. A content display method in a content display device for displaying content on a display screen, comprising:

a first operation detection step of detecting a first operation on a displayed content;

a first display step of determining a display magnification ratio based on the operation quantity of the first operation and displaying a display image of the content that has been subjected to a first image processing for enlargement or reducing by the display magnification ratio; and

,

a second display step of displaying a display image of the content that has been subjected to a second image processing when the display magnification ratio falls beyond a first threshold range.

8. A non-transitory recording medium recorded with a program for causing a computer that displays content on a display screen, to execute:

a first operation detection step of detecting a first operation on a displayed content;

a first display step of determining a display magnification ratio based on the operation quantity of the first operation and displaying a display image of the content that has been subjected to a first image processing for enlargement or reducing by the display magnification ratio; and

,

a second display step of displaying a display image of the content that has been subjected to a second image processing when the display magnification ratio falls beyond a first threshold range.
