Information processing device

An information processing device configured to display a whole or a part of an entire image on a display, comprising:

• a first reception unit configured to receive a change instruction to change a display image;
• a display image generation unit configured to identify, according to the change instruction, a scaling factor of an image to be displayed or information related to the scaling factor and to generate a display image, which is the whole or a part of the entire image;
• a second reception unit configured to receive input from a user;
• and
• an input processing unit configured to process the input received by the second reception unit,
• wherein the input processing unit includes:
• a position information acquisition unit configured to acquire position information that identifies a position in the display image at which the second reception unit has received the input;
• and
• an associating unit configured to associate the position information acquired by the position information acquisition unit with the input from the user, the position information including the scaling factor or information related to the scaling factor of the display image in which the second reception unit has received the input.

A computer program embedded in a non-transitory computer-readable recording medium and adapted to cause a computer to implement a function of displaying at least a part of an image on a display, comprising:

• a module configured to receive a change instruction to change a display image;
• a module configured to identify, according to the change instruction, a scaling factor of an image to be displayed or information related to the scaling factor and to generate a display image, which is a whole or a part of an entire image;
• a module configured to acquire superimposition data for display over the display image, the superimposition data including a scaling factor or information related to the scaling factor;
• a module configured to determine whether the scaling factor of the display image and either the scaling factor or the information related to the scaling factor included in the superimposition data are in a predetermined relationship;
• and
• a module configured to generate a superimposition image to be displayed on the display image based on the superimposition data.
