IPC: G09G1/16
Filed: 1988-09-06
Abstract: PURPOSE:To improve the definition (resolution or the like) of the display on a display device (display on a display screen) by selecting the direction, in which the number of picture elements should be continuously increased, based on the variation of the picture element value in each direction. CONSTITUTION:The direction of scanning lines is determined based on the variation in each direction (the horizontal direction and the vertical direction) of the picture element value stored in a picture memory 6 by actions of a horizontal-direction read signal generator and a vertical-direction read signal generator for scanning line direction determination. Consequently, the horizontal direction or the vertical direction is automatically properly selected as the direction of scanning lines (the horizontal direction or the vertical direction in which the continuous increase of the number of picture elements should be permitted) is automatically selected so that the definition on the display screen of a display device 19 is improved. Thus, the definition of the display on the display device is improved.
