<p>PROBLEM TO BE SOLVED: To provide a flexible writing function.SOLUTION: A first detection unit 111 detects a write operation from a user to a display image 121 that is displayed by a display device 120. When the write operation is detected by the first detection unit 111, a storage unit 112 stores first feature information which is calculated from the display image 121 and write data 101 which is written by the write operation, in association with each other. A second detection unit 113 detects the display, which is performed by the display device 120, of a display image 123 from which second feature information that is identical or similar to the first feature information stored by the storage unit 112 is calculated. When the display of the display image 123 is detected by the second detection unit 113, a control unit 114 causes the display device 120 to display the write data 101, which is stored by the storage unit 112 in association with the first feature information, together with the display image 123.</p> |
