Taking more than one image of the same scene. Computational imaging is used in machine vision to capture an image with more detail. Using high-speed cameras, several photos are taken, and algorithms are used to derive a single image.
Although all modern digital cameras perform a certain amount of digital processing to derive the final result, computational imaging works with multiple images. It is able to produce a sharper image and a greater sense of depth. For example, machine vision systems can detect flaws in newly created products, which they would not otherwise be able to do with a single image from a regular camera. See
