Title: “Overcoming the Full-Well Capacity Limit: High Dynamic Range Imaging Using Multi-Bit Temporal Oversampling and Conditional Reset”
Thomas Vogelsang, Michael Guidash, Song Xue, Rambus
The dynamic range of current CMOS image sensors are limited by each pixel’s “full-well” capacity, which is the ability of the pixel to collect photo-electrons into a quantum well bucket during the exposure period. Binary pixels employ advanced oversampling methods where each pixel has an order of magnitude higher effective full-well capacity compared to conventional CMOS active pixels, resulting in images with a corresponding improvement in dynamic range.
During this presentation, Dr. Vogelsang will discuss the system design of the Rambus Binary Pixel technology, introduced earlier this year. Specifically, he will describe how the high dynamic range image sensor oversamples the incident light by using the ADC output at each sampling and resetting the pixel only if a threshold has been exceeded. Dr. Vogelsang will present results from an image sensor test-chip that demonstrates dynamic range extension by a factor of 14 compared to a conventional sensor in the same technology.
