EE Times Under the Hood - June 23, 2008 - (Page U17)

Introducing VEE: Visual Enhancement Engine VEE enables a TV-quality visual experience on mobile devices while dramatically reducing the LCD backlight to improve battery life These three Use Cases illustrate how QuickLogic’s proprietary VEE solution greatly enhances image and video quality by dynamically compressing the display range to match the characteristics of the LCD, with the intended viewing experience of the source content, resulting in a substantially better viewing experience under any conditions. VEE technology transforms the mobile multimedia experience by: ! Significantly enhancing image/video quality through dynamic range control ! Allowing superior viewing image/video quality under low backlight or bright ambient light conditions Use Case 1 – Improved Video Quality A commuter goes from a train station to outdoors, while watching a movie, with backlight automatically compensated. One benefit of VEE’s visibility improvements is that the mobile device does not require a powerful backlight in order to provide daylight viewing. The enhancement engine will compensate for the display’s reduced contrast, ensuring a consistent high-quality viewing experience despite lighting changes. G Original Video Video with VEE on A Use Case 2 – Battery Life Extension A traveler low on battery power can now finish a two-hour movie while on an airplane because VEE automatically adjusts in real time to compensate for reduced backlight. With traditional display technology, developers have only two options for overcoming viewability concerns. One is to increase backlighting, particularly in high ambient light conditions. However, for mobile device designers, this option has a serious drawback—increased power consumption. The backlight for a mobile display consumes between 30% and 60% of the device’s power budget. The VEE technology from QuickLogic automatically compensates for the reduced backlight thus increasing battery life, while providing a satisfactory viewing experience. G Backlight reduced by 70% Without VEE Backlight reduced by 70% Compensated by VEE A Use Case 3 – Enhanced Still Pictures A tourist takes a picture while sightseeing and uses VEE to check if he captured all the details that were lost on the built-in LCD display due to limited contrast ratio. The VEE enhancements arise from the re-mapping of image data to amplify subtle variations and make them more apparent to the eye. This imagedependent remapping addresses display limitations in two ways. First, it ensures that image details are preserved against truncation by the display’s limited input range. Second, by taking into account the surrounding data values, the mapping enhances image detail in light and dark image areas appropriately.
