In an image display apparatus including a display unit for displaying an image of an inputted video signal thereon with a predetermined field frequency and a predetermined number of scanning lines using vertical and horizontal synchronizing signals for deflection of display in response to the inputted video signal, a first converter converts an inputted first video signal, having a first field frequency which is lower than the predetermined field frequency and having the predetermined number of scanning lines, into an output second video signal having the predetermined field frequency which is and the predetermined number of scanning lines, and having outputs the output second video signal to the display unit. Further, a second convertor converts an inputted third video signal, having a first number of scanning lines which is smaller than the predetermined number of scanning lines and having the predetermined field frequency into an output fourth video signal having the predetermined field frequency and the predetermined number of scanning lines, and outputs the output fourth video signal to the display unit.
