Abstract

We present a 5μm-pitch, 3D-BSI 1Megapixel dual-time-gated color SPAD image sensor enabling a simultaneous output of dual images. The developed SPAD image sensor is verified to operate as an RGB-D sensor without complex image alignment. In addition, a novel HDR technique utilizing pileup effect with two parallel in-pixel memories is validated for dynamic range extension in 2D imaging, achieving a dynamic range of 119.5dB. The proposed architecture provides dual image output with the same field-of-view, resolution, and frame timing, and is promising for efficient sensor fusion.
