PROBLEM TO BE SOLVED: To provide a general use image display adjusting device which can automatically adjust the emphasis coefficient for the displayed image, and suppress the image quality deterioration due to the emphasis by using a small-scale circuit, and set up the optimum emphasis coefficient for each panel and image. SOLUTION: This image display adjusting device obtains the output signal improved in response by making the memory 102 store one frame of the input signals f1 to obtain the difference between the input signals f0 one frame earlier and the current frame f1 in a difference means 103, and multiplying the emphasis coefficientαto this difference signals (f1-f0) in a multiplication means 106, then adding the multiplied output signalα(f1-f0) to the current input signal f1 in an adder 107 as the correction data. Further, it has emphasis coefficient control means 104, 105 to input the signal f1 or difference signal (f1-f0) to apply predetermined decoding, and to output the emphasis coefficientαmatching the input signal or the difference signal by using the decoded values.
