Claim:
An image display system, comprising: a display device; an input section to which video signals of an interlace scanning system are inputted; a signal converter section which increases horizontal scanning lines of said video signals inputted to said input section in number by a factor of at least two, and which generates first fields and second fields, each of said first fields and said second fields including effective scanning lines used for displaying said video signals and ineffective scanning lines not used for displaying said video signals, with said effective and ineffective scanning lines being arranged alternately in each of said first and second fields; and a display control section which controls said display device such that said display device displays said first and second fields generated by said signal converter section, alternately in terms of time, wherein said display control section controls said display device such that positions of said effective scanning lines of said first fields correspond with those of said ineffective scanning lines of said second fields, and positions of said ineffective scanning lines of said first fields correspond with those of said effective scanning lines of said second fields.
