1. An information processing apparatus for reproducing content data which is viewed by a plurality of users simultaneously, the information processing apparatus comprising: a single imaging circuit configured to pick up an image of a plurality of users of the information processing apparatus simultaneously; and circuitry configured to reproduce the content data, generate a mirror image of the image of the plurality of users picked up by the imaging circuit, detect a position of a pointer of at least one of the plurality of users in the mirror image, measure a distance from the information processing apparatus to the plurality of users extract an area containing the detected position of the pointer of the at least one of the plurality of users from the mirror image, based on the measured distance to the plurality of users, and composite the extracted area from the mirror image onto an image of the content data reproduced so that the pointer appears partially transparent on the image of the content data.
