Korean image sensor company Maru LSI publishes a Youtube demo of its VIPS (Vertically Integrated Photodiode Structure) sensor. The sensor was presented in IISW 2007 paper and has deep PD underneath RGB PDs:
In the video, the left picture shows the image from Color CCD camera and the right one shows the results from VIPS image sensor. VIPS image shows the shrunk RGB image and IR image at the bottom and composed image in VGA size. The composition rule is simple addition of two images when the RGB level is lower than the preset threshold:
