The imaging apparatus 10 includes the lens 11, the image sensor 12 and the controller 14. A light receiving surface of the image sensor 12 is disposed on a focused position of an object by the lens 11, the object being located at a specific object distance. The controller 14 generates one or more second images from a first image obtained from the image sensor 12, the focus position of the second images being changed to an object distance different from a specific object distance, and determines the presence of foreign matters adhered to the surface on the object side of the lens, on the basis of the focused state of the second image.
