Abstract
A method and an apparatus for detecting bubbles and/or creases on labeled containers. Bubbles/creases can be detected without comparison with a previously stored reference recording by virtue of the fact that a label to be examined is illuminated with a first flash of light, for example using the surface radiator, and is recorded in a first camera image, that the label is also illuminated with at least one second flash of light, for example using the directional radiator, with a changed directional characteristic and is recorded in a second camera image, and that a brightness difference between the first and second camera images is calculated.
