An image display adjusting device wherein a difference portion obtains a difference between an input signal f 0 preceding by one frame as an input signal f 1 held by one frame by a memory portion and a current input signal f 1 , a multiplication portion 106 multiplies this difference signal (f 1 -f 0 ) by a highlight coefficient alpha, and an addition portion 107 adds a multiplication output signal alpha (f 1 -f 0 ) thereof as correction data to the current input signal f 1 to obtain an output signal having its responsiveness improved, the device provided with highlight coefficient controlling portions for performing predetermined decoding by inputting the input signal f 1 or the difference signal (f 1 -f 0 ) and converting it to a signal having a change characteristic different from that signal and outputting a highlight coefficient alpha adapted to the input signal or the difference signal by using that decode value.
