PROBLEM TO BE SOLVED: To easily obtain the contents of documents which are hard to see or is hard to read documents.SOLUTION: A scanner 11 converts documents of paper medium arranged by a receiver into digital data, and a pickup image generating part 17a generates a pickup image from the digital data. A division part 17b divides the pickup image into a plurality of regions, and a display control part 17c controls a display part 12 to display the pickup image. An optical sensor of the display part 12 specifies the position of visible light emitted from a remote controller 20 on the display part 12, and a specification part 17d specifies the position of the visible light specified by the optical sensor on the display part 12 and specifies a region corresponding to the acquired position from a plurality of regions divided by the division part 17b. An expanded image generating part 17e generates an expanded image obtained by expanding the region specified by the specification part 17d, and a display control part 17c controls the display part 12 to display the expanded image. |
