A cooling system for cooling an interface card is provided. In an example embodiment, luminance ratio values and residual values in color channels of a color space are generated on an individual pixel basis based on a high dynamic range image and a derivative tone-mapped image that comprises one or more color alterations that would not be recoverable from the TM image with a luminance ratio image. The apparatus includes a detecting unit and a coupled computing unit. Finally, and responsive to the recorded information, the method forms the frequency hopping sequence. The front dial assembly is cantilevered over the rotating pointer to permit pointer rotation.
