ABSTRACT:
Disclosed herein is an image display unit comprising a brightness circuit which has an output brightness characteristic in which the logarithmic value of the output density of an input image signal becomes smaller as the value of the image signal becomes larger. The output brightness characteristic is set so that a rate of change, which represents a change in the logarithmic value of the output brightness with respect to a change in the signal value, in the low signal value region of the image signal becomes smaller than that in the intermediate and high signal value region of the image signal.
