Abstract:
1. An image display apparatus for performing image display processing, comprising: an interlace-to-progressive converter configured to perform signal conversion processing for receiving an interlace signal to convert the interlace signal into a progressive signal including information on interpolated pixels generated by interpolation processing; a frame controller configured to divide an input image frame in a time-division manner to generate a plurality of sub-frames; a high-frequency-enhanced sub-frame generator configured to perform filtering processing on the plurality of sub-frames generated by the frame controller to generate high-frequency-enhanced sub-frames; a high-frequency-suppressed sub-frame generator configured to perform filtering processing on the plurality of sub-frames generated by the frame controller to generate high-frequency-suppressed sub-frames; a first output controller configured to alternately output the high-frequency-enhanced sub-frames generated by the high-frequency-enhanced sub-frame generator and the high-frequency-suppressed sub-frames generated by the high-frequency-suppressed sub-frame generator; a gain controller configured to adjust an output level of sub-frame images corresponding to the high-frequency-enhanced sub-frames and the high-frequency-suppressed sub-frames output from the first output controller; a second output controller configured to receive an output from the first output controller and an output from the gain controller to output an output-level-adjusted signal output from the gain controller as a signal corresponding to the interpolated pixels generated by the interlace-to-progressive converter and to output an output-level non-adjusted signal output from the first output controller as an original pixel signal other than the signal corresponding to the interpolated pixels; and a display unit configured to perform frame-hold-type display processing and to alternately display the high-frequency-enhanced sub-frames and the high-frequency-suppressed sub-frames output from the second output controller.
