Input/output apparatus for displaying superposed images including a handwritten image

An input/output apparatus, comprising:

• a storage;
• a display;
• a handwriting input to which a handwritten image is input;
• a first display controller configured or programmed to display on the display, when a handwritten image is input through the handwriting input while an image based on data stored in the storage is being displayed on the display, the handwritten image in addition to the image based on the data;
• a handwritten data creation controller configured or programmed to create handwritten data that includes data specifying information specifying the data stored in the storage and represents the handwritten image input through the handwriting input, and to store the created handwritten data in the storage;
• a first termination controller configured or programmed to terminate the display of the handwritten image when the display of the image based on the data stored in the storage is terminated;
• a reading-out controller configured or programmed to read out, when the handwritten data stored in the storage is read out, data specified by the data specifying information included in the read-out handwritten data;
• and
• a second display controller configured or programmed to display on the display an image based on the data read out by the reading-out controller and a handwritten image based on the handwritten data;
• wherein
• the handwritten data creation controller is configured or programmed to create, when a handwritten image is input through the handwriting input in a state where the image based on the data stored in the storage includes a plurality of images and one of the plurality of images is displayed on the display, handwritten data including association information in which the handwritten image is associated with said one image,
• the input/output apparatus further comprising:
• a fourth display controller configured or programmed to display on the display one image based on data representing a plurality of images and a handwritten image associated with said one image on the basis of the association information included in the handwritten data;
• and
• a second termination controller configured or programmed to terminate, when the display of said one image is terminated and another image among the plurality of images is displayed on the display, the display of the handwritten image.
