Resumen: This live demonstration showcases a high dynamic range technique that compresses wide ranges of illuminations into the available signal range with a single exposure. In order to accomplish such compression, concurrent sensing-processing takes place at the focal plane, weighing the influence of local and global illumination on each pixel response during the image capture. This process is driven by an on-line analysis of the image histogram that also enables the dynamic accommodation of changing illumination conditions. The proposed technique has been implemented on a prototype smart image sensor achieving a dynamic range of 102dB.
