(a) Example of a dual exposure process of an input pixel intensity, where the long exposure time equals four times the short exposure time . The top subfigure portrays the sensor output values for long- and short-exposure images, while the bottom subfigure depicts the corresponding SNR curves. (b) Images originating from two exposure times after weighted normalization, when using switching between two exposures. The top subfigure portrays the sensor output values for a combined image, while the bottom subfigure depicts the resulting SNR curve.
