Abstract: An image display system includes a host side for executing an application and transmitting image data having a P dot width in a block unit with the number of m dots as the width of the block. A panel side is connected through a digital I/F line to the host side, which converts the image data having a P dot width by using magnification to produce data having an R dot width and then displays the image data. The panel side executes scaling by using a block having an integral value obtained by a R×m/P set as a dot width and a block having a dot width of an added integral value obtained by adding 1 to the integral value, and converts by magnification the image data received from the host side in block unit based on the executed scaling and displays the image data on a panel.
