Kind Code:

Abstract:

A screen control means (106) determines a priority, a scaling factor and a picture synthesizing position. A picture selecting means (101) selects a picture from among a plurality of inputted pictures in accordance with the priority. Picture processing means (102) enlarges or reduces the selected picture in accordance with a scaling factor. A movement detecting means (103) detects the parts of the picture processed by the picture processing means (102) which show no movement. A frequency analyzing means (104) detects the parts of the picture processed by the picture processing means which have no features. An adaptive picture synthesizing means (105) synthesizes the enlarged or reduced picture at a picture synthesizing position indicated by the movement detecting means (103) and the frequency analyzing means (104). With this process, even if a display object picture is added in addition to an opponent picture and a self-picture, effective synthesized display can be obtained and, even if the resolution of a display device is changed, the change can be flexibly coped with, so that it can be avoided that the main picture part on a main screen is covered by a sub-screen.
