An image processing apparatus includes a synthesizing unit which synthesizes a drawn image drawn on a displayed image on a display device with the displayed image; a content data receiving unit which receives content data; a content data conversion unit which converts the received content data to image data; an external snapshot generation unit which generates an external snapshot to be displayed on the display unit based on the converted image data and stores the external snapshot in a storage unit; and a display control unit which displays the synthesized image by the synthesizing unit on the display device and also displays an object corresponding to the external snapshot in a selectable manner so that the external snapshot is displayed on the display device when the object is selected.
