摘要： A detection unit which includes an image display panel, brightness averaging unit, scene changeover detection unit, and brightness suppression unit in order to provide an image display apparatus having an ABL that does not give the observer any visual sense of incompatibility without increasing the circuit scale determines the presence/absence of a scene changeover on the basis of the frame differential or second order differential of the average brightness. If a scene changeover takes place, the display brightness is changed quickly, and if no scene changeover occurs, changed slowly.
