Associating digital ink markups with annotated content

An information processing system, comprising:

• an electronic whiteboard;
• and
• an information processing apparatus communicable with the electronic whiteboard, wherein
• the information processing apparatus includes first circuitry configured to:
• in response to receiving a notification indicating that the electronic whiteboard receives a predetermined instruction, change attribute information of a stroke image associated with the predetermined instruction to specific attribute information, the specific attribute information identifying information in an area defined by the stroke image as information to be extracted;
• and
• to transmit the specific attribute information to the electronic whiteboard, and
• the electronic whiteboard includes second circuitry configured to:
• receive the predetermined instruction;
• and
• in response to receiving the specific attribute information, to control a display provided with the electronic whiteboard to display the stroke image associated with the predetermined instruction as a stroke image whose attribute information is the specific attribute information,
• wherein:
• the predetermined instruction is received when an instruction button of the display is tapped,
• the stroke image associated with the predetermined instruction is a stroke image that is input after the predetermined instruction is received,
• the circuitry is further configured to:
• extract, as important matter information, information identified as the information to be extracted, from page data indicating a page of a screen displayed on the display;
• and
• store the important matter information in an important matter database,
• the important matter information is image data in the area defined by the stroke image whose attribute information is the specific attribute information, and
• the predetermined instruction which is received causes both the change of attribute information of the stroke, and the extracting, as important matter information, the information identified as the information to be extracted.

A display control method performed by an electronic whiteboard, the method comprising:

• receiving a predetermined instruction;
• in response to receiving the predetermined instruction, changing attribute information of a stroke image associated with the predetermined instruction to specific attribute information, the specific attribute information identifying information in an area defined by the stroke image as information to be extracted;
• and
• controlling a display provided with the electronic whiteboard to display the stroke image associated with the predetermined instruction as a stroke image whose attribute information is the specific attribute information,
• wherein the receiving includes receiving the predetermined instruction in response to tapping an instruction button of a display, and
• wherein the stroke image associated with the predetermined instruction is a stroke image that is input after the predetermined instruction is received,
• wherein the method further comprises:
• extracting, as important matter information, information identified as the information to be extracted, from page data indicating a page of a screen displayed on the display;
• and
• storing the important matter information in an important matter database,
• wherein the important matter information is image data in the area defined by the stroke image whose attribute information is the specific attribute information, and
• wherein the predetermined instruction which is received causes both the change of attribute information of the stroke, and the extracting, as important matter information, the information identified as the information to be extracted.
