| 20110007213 | IMAGE DISPLAY APPARATUS AND METHOD OF CONTROLLING THE SAME - This invention provides an image display apparatus capable of, even in an environment different from that of a theater, reproducing a video of the same atmosphere as that of a film movie screened in the theater. In the image display apparatus, input image data is multiplied by a predetermined ratio to obtain first image data. The first image data is subtracted from the input image data to obtain second image data. Buffer memories temporarily store the first and second image data, respectively. The first and second image data stored in the buffer memories are read and displayed in alternate order. At this time, the predetermined ratio is adjusted so as to set a flicker of the displayed image to a predetermined level. | 01-13-2011 |
