Single-Exposure HDR Technique Based on Tunable Balance Between Local and Global Adaptation
(Institute of Electrical and Electronics Engineers, 2016)
This brief describes a high-dynamic-range technique that compresses wide ranges of illuminations into the available signal range with a single exposure. An online analysis of the image histogram provides the sensor with ...

Image Sensing Scheme Enabling Fully-Programmable Light Adaptation and Tone Mapping with a Single Exposure
(Institute of Electrical and Electronics Engineers, 2016)
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 ...

A 151 dB high dynamic range CMOS image sensor chip architecture with tone mapping compression embedded in-pixel
(Institute of Electrical and Electronics Engineers, 2015)
This paper presents a high dynamic range CMOS image sensor that implements an in-pixel content-aware adaptive global tone mapping algorithm during image capture operation. The histogram of the previous frame of an auxiliary ...
