A fuel supply system and method thereof that utilizes an off-gas in addition to the primary fuel to lower the emissions of a gas turbine combustion system is disclosed. Each element processor stores pixel data of a search window block, which is a corresponding reference picture image pixel block, and obtains an evaluation function value component with respect to the template block pixel data. When an \u201cend of examination\u201d option in the workflow list is selected, job status information is displayed in the parameter setting area, prompting an operator to check the status of the job selected in set reconstruction parameters. The first rail section has a first rib and a first protruding section; and the second rail section has a second rib and a second protruding section. In another embodiment, the transient recovery circuit controls a dedicated transient phase in a multiphase switching regulator. Specifically, to concentrate image parts of image signals of N pixels, pixel values of all consecutive pixels in the main scanning direction are added, and the pixels are rearranged with a screen-line position as a reference situated at the center, based on the addition result.
