Image Sensing Scheme Enabling Fully-Programmable Light Adaptation and Tone Mapping with a Single Exposure: Demo

This demo showcases a High Dynamic Range (HDR) technique recently reported. We demonstrate that two intertwined photodiodes per pixel can perform tone mapping under unconstrained illumination conditions with a single exposure. The proposed technique has been implemented on a prototype smart image sensor achieving a dynamic range of 102dB. It opens the door to the realization of smart cameras and vision sensors capable of rendering HDR images free of artifacts without requiring any digital post-processing at all.
