Abstract
An object of the present invention is to realize a transmission distortion correction system for allowing an image signal including a plurality of picture signals to be corrected, and to realize an image signal transmitter and an image display unit. The image display unit of the present invention includes: a second reference signal generation means for generating a second reference signal similar to a first reference signal regarding the image signal in which the first reference signal is inserted into each of the plurality of picture signals by the image signal transmitter; a plurality of waveform equalizers provided that correspond to the plurality of picture signals and that include a filter circuit capable of setting a characteristic thereto; and a control portion for inputting the plurality of picture signals, analyzing a characteristic of a transmission path between the image signal transmitter and the image display unit upon detecting the first reference signal in the input picture signals by comparing the first reference signal with the second reference signal, and setting a characteristic inverse to the analyzed transmission path characteristic to a filter circuit of the waveform equalizers that correspond to the input picture signals.
