Information Processing Device And Information Processing Method

An information processing method comprising:

• reading from a memory hierarchical data that comprises image data of different resolutions that is hierarchized in order of resolution and outputting the data to a display device;
• acknowledging a user request for movement of a viewpoint in a virtual space which is defined by an image plane and a distance from the image plane;
• changing an area to be displayed on the display device in response to the request to move the viewpoint;
• and
• executing a process defined as being associated with a predetermined area of an image, when the view point meets a condition for activating the process,
• wherein the condition is defined by the positional relationship between the predetermined area defined on the image plane and an area that is determined by the viewpoint and that is displayed on a screen.

A computer program embedded in a non-transitory, computer-readable recording medium, comprising:

• a module configured to read from a memory hierarchical data that comprises image data of different resolutions that is hierarchized in order of resolution and configured to display the data on a display device;
• a module configured to acknowledge a user request for movement of a viewpoint in a virtual space which is defined by an image plane and a distance from the image plane;
• a module configured to change an area to be displayed on the display device in response to the request to move the viewpoint;
• and
• a module configured to execute a process defined as being associated with a predetermined area of an image, when the view point meets a condition for activating the process,
• wherein the condition is defined by the positional relationship between the predetermined area defined on the image plane and an area that is determined by the viewpoint and that is displayed on a screen.

A non-transitory, computer-readable recording medium having embodied thereon a computer program, the computer program comprising:

• a module configured to read from a memory hierarchical data that comprises image data of different resolutions that is hierarchized in order of resolution and configured to display the data on a display device;
• a module configured to acknowledge a user request for movement of a viewpoint in a virtual space, the viewpoint being defined by both an image plane and a distance from the image plane;
• a module configured to change an area to be displayed on the display device in response to the request to move the viewpoint;
• and
• a module configured to execute a process defined as being associated with a predetermined area of an image, when the view point meets a condition for activating the process,
• wherein the condition is defined by the positional relationship between the predetermined area defined on the image plane and an area that is determined by the viewpoint and that is displayed on a screen.
