DISTRIBUTED PROCESSING FOR VIDEO ENHANCEMENT AND DISPLAY POWER MANAGEMENT |
摘要 |
In visual display devices such as LCD devices with backlight illumination (fig. 6 element 5), the backlight typically consumes most of device battery power. In the interest of displaying a given pixel pattern at a minimized backlight level, the pattern can be transformed while maintaining image quality, with a transform determined from pixel luminance statistics (fig. 6 element 4). Aside from, or in addition to being used for such minimizing, a transform also can be used for image enhancement, for a displayed image better to meet a visual perception quality. In either case, the transform preferably is constrained for enforcing one or several display attributes. In a network setting, the technique can be implemented in distributed fashion, so that subtasks of the technique are performed by different, interconnected processors such as server, client and proxy processors.
