Display control of page data by annotation selection

An information processing method comprising:

• receiving an input of a user to control display of an electronic document;
• displaying a page of the electronic document on a screen;
• changing the display of the page between an expansion-display that displays expanded display of a portion of the page at a magnification and a reduction-display that displays glancing over the entire page;
• adding at least one annotation object on the portion of the page when the page is displayed in the expansion-display;
• and
• storing page data of the page of the electronic document;
• storing the magnification for the expansion-display that displays a part of the electronic document when the annotation data is added to the portion of the page;
• and
• changing the display on the screen from the reduction-display to the expansion-display having the stored magnification, in response to receiving an input of the user to select the at least one annotation object.

A non-transitory computer readable medium storing a program causing a computer to execute a process for performing processing of electronic information, the process comprising:

• receiving an input of a user to control display of an electronic document;
• displaying a page of the electronic document on a screen;
• changing the display of the page between an expansion-display that displays expanded display of a portion of the page at a magnification and a reduction-display that displays glancing over the entire page;
• adding at least one annotation object on the portion of the page when the page is displayed in the expansion-display;
• and
• storing page data of the page of the electronic document;
• storing the magnification for the expansion-display that displays a part of the electronic document when the annotation data is added to the portion of the page;
• and
• changing the display on the screen from the reduction-display to the expansion-display having the stored magnification, in response to receiving an input of the user to select the at least one annotation object.

An information processing apparatus comprising:

• a display that displays a page of an electronic document;
• a memory that stores data of the page of the electronic document, an annotation added to a portion of the page of the electronic document that is displayed in an expansion-display that displays an expanded display of the portion of the page at a magnification, and annotation data that indicates at least one of the portion of the page displayed on the display and the magnification of the portion of the page displayed on the display;
• an input unit that receives a first user input to at least one of add the annotation to the portion of the page of the electronic document displayed in the expansion-display and change at least one of the portion of the page in the expansion-display and the magnification of the portion of the page in the expansion-display, and a second user input to select the annotation;
• and
• a processor that stores the at least one of the portion of the page in the expansion-display and the magnification of the portion of the page in the expansion-display in the memory as the annotation data, in response to the input unit receiving the first user input, controls the display to display the portion of the page at the magnification based on the annotation data stored in the memory, in response to the input unit receiving the second user input, and controls the display to change between the expansion-display and a reduction-display that displays the entire page.
