METHOD AND DEVICE FOR ENHANCING IMAGE REPRODUCTION OF TELEVISION RECEIVER

摘要

PROBLEM TO BE SOLVED: To reduce a difference from frequency responses of each channel in a television receiver. SOLUTION: The method of this invention is a method to enhance image reproduction by a television receiver that is characterized in that a video frequency response in measured for each channel of the television receiver when each antenna signal corresponding to each channel is fed to an antenna input of the television receiver, the video frequency response is corrected by frequency detuning corresponding to a related channel when the response is deviated from a prescribed reference, and the correction is stored by overwriting frequency data with respect to the related channel or by adding the corresponding correction value to the frequency data of the related channel of the television receiver.
