By using imaging and lighting control programs, lighting signals were transferred to a monolithic chip light control circuit, so that two white light LEDs could generate instantaneous flash within different preset time intervals. The iris region is searched from outside to inside by simply calculating the objective function value at discretely sampled radius and center. A new interpolation method is used for merging two images to complete an image without any reflective dot, as well as a safe lighting design, and double-pulse iris imaging system. |
