The last patent for today is from Samsung and is about creating DSLR-like bokeh for compact cameras:
"While the primary lens is capturing the full-resolution image, a secondary lens and sensor captures another image with the sole purpose of evaluating the relative distances of areas in the image. (In some configurations, the camera may actually be a 3D camera, while in other configurations, it may truly be a secondary lens and sensor.) Then, the camera merges the data with the primary image to create a depth map and applies a graduated blur based on this depth map."
