    From Wikipedia: In optics, a circle of confusion is an optical spot caused by a cone of light rays from a lens not coming to a perfect focus when imaging a point source. It is also known as disk of confusion, circle of indistinctness, blur circle, or blur spot. Personal note: I took a picture of a group of small lights and deliberately put my lens out of focus.
