<p>An image signal of interlace scanning system is converted to a signal of non-interlace scanning system and an image is displayed on a liquid crystal display panel with a given magnification. To reduce flickering, in-field line interpolation is so performed that data in the same image line position in the original image is given to the display lines of the liquid crystal display panel in each even or odd field. When the original image is magnified, for example, triply, the image line position of the original image given to the second display line on the liquid crystal panel is L 2(2/3). The image line position is the one in which the distance between the two image lines (L1, L3) of the original image in an odd field is internally divided at 5:1, or the one in which the distance between the two image lines (L2, L4) in an even field is internally divided at 1:2. Interpolation is carried out using the internal ratios as the interpolation coefficient, and hence display line data is generated for each field from the data on the two image lines. <IMAGE></p> |
