Abstract: A method of processing original still picture data representing an original still image and stored in a video memory and storing processed still picture data representing a processed still image in a predetermined location of the video memory comprising the steps of setting an XY orthogonal coordinate system on the video memory, setting a reference line (y=Ym) parallel to one of X and Y axes of the orthogonal coordinate system and passing through a point of intersection of lines M(Xm,Ym), each of which connects corresponding pixels P1(x1,y1) ; P2(x2,y2) of the original and processed still images (A,B,C,D ; A2B2C2D2), moving the pixel data on a line of the original still image parallel to the reference line and furthest from the reference line to addresses of the video memory forming a line of the processed still image, and repeating the preceding step for pixel data on lines of the still image parallel to the reference line and second furthest from the reference line and succeeding lines, thereby the processed still picture data representing the processed still image being stored in the video memory. An apparatus for processing original still picture data is also provided.

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 data 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.
