Image Sensing Scheme Enabling Fully-Programmable Light Adaptation and Tone Mapping with a Single Exposure
This letter presents new insights into 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.

| Sumario: | This letter presents new insights into 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. Experimental results attained from a prototype chip confirm the proposed theoretical framework. It opens the door to the realization of imagers providing HDR images free of artifacts without requiring any digital post-processing at all. |
