摘要

讨论了一种用于高动态范围(HDR)成像的CMOS视频传感器。与传统的HDR成像方法不同，HDR成像方法是将不同曝光次数的帧进行数字组合以获得HDR帧，而HDR成像方法是在像素级传感器中通过将不同曝光次数的子像素进行数字组合以获得HDR像素。在HDR模式下，原型视频传感器的动态范围比正常模式提高了26 dB。

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

A CMOS video sensor for high dynamic range (HDR) imaging is discussed. Unlike traditional memory-intensive 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 26 dB improvement in dynamic range over normal mode.
