Flash image quality enhancement by compensating the quantity of flash light

The most of mobile phone camera are equipped with LED flash to acquire image under dark illuminant. However, the power of LED flash is not enough to illuminate the background area of scene as it becomes diminished in a distance. Moreover, mobile phone camera still suffers from low dynamic range. The...

Description
Summary:The most of mobile phone camera are equipped with LED flash to acquire image under dark illuminant. However, the power of LED flash is not enough to illuminate the background area of scene as it becomes diminished in a distance. Moreover, mobile phone camera still suffers from low dynamic range. The facts bring unbalanced image in terms of brightness. To solve this problem, we propose method that estimates the intensity of flash light and compensate the difference of flash using flash and no-flash image pair. We confirmed the promising performance in an experiment using mobile phone camera.
