Abstract
A detection apparatus includes an image acquisition interface that acquires a captured image captured by an imaging unit and a controller that generates or acquires a smoothed image yielded by smoothing the captured image. The controller compares the captured image and the smoothed image and detects a low-frequency region having a predetermined spatial frequency spectrum from the captured image.
