A CMOS video sensor for High Dynamic Range (HDR) imaging

Abstract: A CMOS video sensor for High Dynamic Range (HDR) imaging is discussed. Unlike traditional memoryintensive methods for HDR imaging where frames with different exposure times are digitally combined to obtain an HDR frame, HDR imaging is accomplished in the sensor at pixel level by digitally combining sub-pixels with different exposure times to obtain an HDR pixel. In HDR mode, the prototype video sensor demonstrated a phenomenal 26dB improvement in dynamic range over normal mode.

“…One approach for HDR video is to have groups of neighboring pixels on a sensor use different exposure times [13]. However, this approach results in a loss of spatial resolution and may require deblurring of the longer exposures to properly match the short exposures.…”
