Abstract
An image display apparatus includes the following elements. An IP converter performs signal conversion processing for converting an interlace signal into a progressive signal including information on interpolated pixels. A frame controller temporally divides an input image frame to generate a plurality of sub-frames. A high-frequency-enhanced sub-frame generator and a high-frequency-suppressed sub-frame generator perform filtering processing on the sub-frames to generate high-frequency-enhanced sub-frames and high-frequency-suppressed sub-frames, respectively. A first output controller alternately outputs the high-frequency-enhanced sub-frames and the high-frequency-suppressed sub-frames. A gain controller adjusts an output level of the sub-frames. A second output controller receives an output from the first output controller and an output from the gain controller to output an output-level-adjusted signal as a signal corresponding to the interpolated pixels and outputs an output-level non-adjusted signal as an original pixel signal. A display unit performs frame-hold-type display processing and alternately displays the high-frequency-enhanced sub-frames and the high-frequency-suppressed sub-frames.
