Blending for wide dynamic range image using different exposure image

We propose an algorithm which blends two different exposure time images to get WDR image. Previous WDR algorithm method is used for the low — luminance single image. In this paper, blending method is applied to two input images with different transfer function in previous WDR algorithm, and WDR algorithm method is applied. As a confirmation method, we used sigma value which is used as a numerical value of image quality. The sigma value indicates the saturation degree of the WDR image or the number of zero value pixels. Simulation result has shown that our algorithm outperformed previous method in terms of image visual quality.
