Information processing device and computer readable recording medium

An information processing device comprising:

• a display that displays an object and an annotation image in a display area, the annotation image being input from an external terminal;
• a detecting unit that detects movement of the object;
• an extracting unit that extracts a changed region caused in the display area by the movement of the object;
• and
• a storage unit that calculates the importance level of the image displayed in the display area based on at least one of information about the changed region and information about the annotation image existing in the changed region, and stores the displayed image in accordance with the importance level.

A computer readable recording medium causing a computer to execute a process for processing information, the computer being connected to a projecting device that projects an annotation image input from an external terminal onto a projection area including an object and a background, the computer being also connected to an image capture device that captures an image of the projection area including the object and the background,

• the process comprising:
• detecting movement of the object from an image captured by the image capture device;
• extracting a changed region that is caused in the captured image by the movement of the object;
• and
• calculating the importance level of the captured image based on at least one of information about the changed region and information about the annotation image existing in the changed region, and storing the captured image in accordance with the importance level.
