Abstract:
1. A method for adjusting the brightness of a first view in a multiple-view display independently of a second view in said multiple-view display, said method comprising: a) displaying a first image with a first array of pixels in said multiple-view display, wherein said first array of pixels is configured to be seen from a first viewing area; b) displaying a second image with a second array of pixels in said multiple-view display, wherein said second array of pixels is configured to be seen from a second viewing area; c) adjusting a first code value of said first image that is displayed with said first array of pixels independently of a second code value of said second image that is displayed with said second array of pixels to effect a visually-perceptible change in said first image as displayed with said first array of pixels wherein said visually-perceptible change is independent of any change in said second image displayed with said second array of pixels; and d) wherein said adjusting said first code value of said first image that is displayed with said first array of pixels comprises creating a first low-pass image and a first high-pass image from said first image, applying a tone scale operation to said first low-pass image thereby creating an adjusted first low-pass image, applying a constant positive gain operation to said first high-pass image thereby creating an adjusted first high-pass image and combining said adjusted first low-pass image with said adjusted first high-pass image.
