Abstract
Method and apparatus for preparing and displaying images uses image characteristics of an area of interest of images to optimize or otherwise determine image characteristics of the entire image to be displayed. The area of interest information may be used in computing a System Synchronized Backlight Control (“SSBC”) profile for the area of interest, and the SSBC profile may be used to adjust the image signal to provide an image in which the image characteristics, e.g., are optimized for the image at the area of interest. The image characteristics and/or SSBC profile information may be provided as metadata included in a video signal data stream. The area of interest may be selected where the image is obtained, where the image is shown or elsewhere, e.g., in an image storage device, image player, etc.
