ABSTRACT:
A picture processor for a video conference device, etc., can be used easily by carrying it into a room other than the video conference room, has an object of enabling the display of the input picture to be switched freely even if the picture of the line drawing is displayed together with the input picture. The picture of a line drawing, etc., is held at the corresponding position even in cases where the display of the input picture is switched by updating the input picture data, which is stored in the input picture memory 40, on the basis of the line drawing date and by writing the picture expressed with the line drawing data directly in the input picture, which is stored in the input picture memory 40.
