Abstract (en)
[origin: EP0593012A2] A video picture written in the bit map memory (4) is displayed in a redetermined area on the display screen (70) of the display device (7) within the computer main body (100). The masking memory (2) having a bit number equal to or less than the number of the pixels of the video picture to be inputted is provided separate from the bit map memory (4). When the pixel data of the video picture data has been inputted, the input pixel data is selectively written in the bit map memory (4) based on the contents of the masking memory (2). In displaying a compressed picture of the input video picture on the display screen, an oblique line generating algorithm is used. <IMAGE>
