Abstract: An inspection device and a method of checking on correct functioning of the inspection process of containers such as bottles, cans or the like, where a container to be inspected is detected optically at least in part, and the image data thus detected is analyzed with an analysis program to detect defective containers. An especially simple and reproducible function test of the analysis program is made possible by the fact that reference image data is input into the analysis program, this reference image data corresponding structurally to the detected image data and being analyzed by the analysis program with the same parameter settings of the analysis program.

Abstract: A process for inspecting transparent containers (B), in which every container is illuminated and at least two exposures of the same container are produced by means of a single CCD camera (K) and evaluated, whereby one exposure images the container profile and the other exposure images the container wall, the exposure time of the CCD camera (K) is changed, between the two exposures, from an exposure time for a container to an exposure time for a container profile. A control device (C2) for changing the sensitivity of exposure of the CCD camera (K) is produced.

Abstract: The invention relates to a method for inspecting transparent containers (B), whereby each container is illuminated and at least two images of said container are taken and analysed by a single CCD camera (K), whereby one image pictures the container profile and the other image pictures the container wall. In between taking both images the exposure time of the CCD camera (K) is altered from a container wall exposure time to a container profile exposure time. Within the device, a controller (C2) is provided for changing the light sensitivity of the CCD camera (K).
