An image display apparatus includes an active-period interlaced-to-progressive (IP) converter configured to convert active periods (video periods) included in interlaced signals into progressive signals; a blanking-period IP converter configured to convert blanking periods included in the interlaced signals into progressive signals; a multiplexer configured to generate and output display data including both the progressive signals associated with the active periods and the progressive signals associated with the blanking periods; and a display unit configured to display the data output from the multiplexer. The blanking-period IP converter is configured to generate the progressive signals associated with the blanking periods by executing IP conversion in which values copied from data included in the interlaced signals or values corresponding to black pixels are set as pixel values of an interpolated field not included in field data of the interlaced signals.
