PROBLEM TO BE SOLVED: To achieve preferable image display with an image display apparatus. SOLUTION: A luminance evaluation value detecting unit 103 obtains the whole sum of the luminance data that is input from an image processing unit 102, and calculates a luminance evaluation value that is the ratio (a display area rate) of the whole sum to the cumulative total value of one frame in a case where all the luminance data exhibits the maximum value. If the luminance evaluation value is judged to be a display area rate of 0.3 or lower, a scanning mode determining unit 108 is controlled so that a scanning operation is performed in a first scanning mode. If the luminance evaluation value is judged to be a display area rate of 0.3 or higher, the scanning mode determining unit 108 is controlled so that a scanning operation is performed in a second scanning mode. The first scanning mode and the second scanning mode are simultaneously selected, or the number of scanning wirings to which a selection signal is applied in two selection periods in a row is different between the first scanning mode and the second scanning mode.
