Electronic whiteboard, method for image processing in electronic whiteboard, and recording medium containing computer program of electronic whiteboard

An electronic whiteboard, comprising:

• a display to display an image, the display including a touch panel;
• event acquisition circuitry configured to acquire an event which has occurred on the display, the event including a “stroke drawing” or a “gesture operation”;
• identifying circuitry configured to identify a type of the event with reference to device information;
• and
• processing circuitry configured to perform processing on the event according to a result of identification by the identifying circuitry,
• wherein:
• the identifying circuitry automatically determines, based on the device information, whether “stroke drawing” by a user's hand is available,
• the identifying circuitry identifies the event as “gesture operation”, when contact with the display is made at two or more points and the identifying circuitry automatically determines that “stroke drawing” by the user's hand is available,
• the identifying circuitry identifies the event as “stroke drawing”, when the identifying circuitry determines that contact with the display is made at one point, and
• wherein, when the identifying circuitry automatically determines that “stroke drawing” by the user's hand is not available when the event is an event by the user's hand, the identifying circuitry identifies the event as “gesture operation”, and when the event is an event with an electronic pen, the identifying circuitry identifies the event as “stroke drawing”.
