PURPOSE: To extract the vector of high picture quality by returning data on a digital picture to first resolution so as to convert it for composing it with high resolution similar to the vector incorporated in the picture. CONSTITUTION: In a block 100, displayed vector data is changed and the pixel picture of a corresponding aliasing prevention vector is generated. In a block 110, pixel data showing the aliasing prevention vector is composed with corresponding pixel data stored in a frame buffer. In a block 140, it is necessary to return data which is read out of the frame buffer before composition to high resolution display so as to convert it. In a block 120, 12 bit/color display on the compound picture is dithered for storing it in the frame buffer in a block 130 later. In the block 180, the digital picture stored in the frame buffer is outputted to the display device of a computer monitor through a look up table in a block 150 later. Thus, the vector of high picture quality can be extracted. |
