PROBLEM TO BE SOLVED: To suppress extremely narrow display area of the video image of a particular terminal if an aspect ratio is different.SOLUTION: A synthesizer unit 130-2 determines "CIF", subordinate to a second group (11:9), to be a second representative image size. A video image (image size: 1080) transmitted from a television conference terminal 200-1 is resized to the image size "CIF" by a resize unit 131-2 (step 3). At this time, to the upper and lower portions of a video image having an aspect ratio of "16:9", a black belt (letter box) is inserted to fit to the aspect ratio of "11:9". A mixing unit 132-2 synthesizes the "CIF" video image with the resized image with a predetermined layout (step S13). The synthesized image size becomes "CIF". The synthesized image is output from the mixing unit 132-2 to a transmitter unit 140, so as to transmit to a television conference terminal 200-2. |
