Recording photos in three dimensions. Most folks think of a photo as a two-dimensional representation of a scene. Stanford University researchers, however, have created an image sensor that also can judge the distance of subjects within a snapshot.
After a photo is taken, image-processing software then analyzes the slight location differences for the same element appearing in different patches—for example, where a spot on a subject’s shirt is relative to the wallpaper behind it. These differences from one subarray to the next can be used to deduce the distance of the shirt and the wall.
