Abstract:
An image display apparatus according to the present invention includes: n of scanning lines, n being an integer of 3 or greater; a scanning circuit that outputs a selection signal for sequentially selecting scanning lines from the n of scanning lines in each transitional selection period, light being to be emitted onto the selected scanning lines; a plurality of display devices that are to form a plurality of pixels that form the plurality of scanning lines; an evaluation circuit that outputs an evaluation value corresponding to the brightness of an image formed by the pixels of each of the plurality of display devices; and a control circuit that changes scanning conditions in the scanning circuit in accordance with the evaluation value, so that the ratio of the total time in term of a unit time of the time when each of the n of scanning lines being selected during the selection periods to the unit time is changed.
