Query: Handheld Multi-Frame Super-Resolution   Compared to DSLR cameras, smartphone cameras have smaller sensors, which
limits their spatial resolution; smaller apertures, which limits their light
gathering ability; and smaller pixels, which reduces their signal-to noise
ratio. The use of color filter arrays (CFAs) requires demosaicing, which
further degrades resolution. In this paper, we supplant the use of traditional
demosaicing in single-frame and burst photography pipelines with a multiframe
super-resolution algorithm that creates a complete RGB image directly from a
burst of CFA raw images. We harness natural hand tremor, typical in handheld
photography, to acquire a burst of raw frames with small offsets. These frames
are then aligned and merged to form a single image with red, green, and blue
values at every pixel site. This approach, which includes no explicit
demosaicing step, serves to both increase image resolution and boost signal to
noise ratio. Our algorithm is robust to challenging scene conditions: local
motion, occlusion, or scene changes. It runs at 100 milliseconds per
12-megapixel RAW input burst frame on mass-produced mobile phones.
Specifically, the algorithm is the basis of the Super-Res Zoom feature, as well
as the default merge method in Night Sight mode (whether zooming or not) on
Google's flagship phone.
