Claim One:
1. An image display apparatus comprising: a controller to change a depth of a three-dimensional (3D) image according to an Average Picture level (APL) of the 3D image; and a display to display the 3D image having the changed depth, wherein the controller includes an APL calculator to calculate the APL of the input 3D image, and a formatter to change a depth of the 3D image according to the calculated APL, wherein when the calculated APL is equal to or lower than a first threshold, the formatter sets the depth of the 3D image to a smaller value as the APL is nearer to a lowest APL value, wherein when the calculated APL is equal to or higher than a second threshold, the formatter sets the depth of the 3D image to a smaller value as the APL is nearer to a highest APL value, and wherein when the calculated APL is higher than the first threshold and lower than second threshold, the formatter sets the depth of the 3D image to be maintained without any change.
