The invention concerns the occurrence of flicker being reduced when an interlaced image signal is converted into a non-interlaced signal and displayed at a desired magnification. Correction coefficients corresponding to the respective even-numbered fields and odd-numbered fields are determined according to the magnification of an image and stored in an ODD coefficient memory and an EVEN coefficient memory. For each process for outputting image data corresponding to each pixel in each line of a liquid-crystal display panel, a corresponding correction coefficient is read from the ODD coefficient memory or the EVEN coefficient memory and provided to an interpolation processing circuit. The interpolation processing circuit interpolates image data of one pixel from image data of four pixels read from a line memory. The correction coefficient is set in such a way that pixel data at the same pixel position within the original image is provided to the same pixel of the liquid-crystal panel in either the even-numbered fields or the odd-numbered fields.
