Abstract
An apparatus for inspecting images is disclosed. In an embodiment an apparatus includes a camera for recording a surface of a printed product, the printed product being movable relative to the apparatus, a first illumination unit of a first type for illuminating a first partial region of a region that is capturable by the camera, a second illumination unit of a second type for illuminating a second partial region of the region that is capturable by the camera, and an evaluation unit for processing image information captured by the camera, wherein the first illumination unit differs from the second illumination unit, and wherein the first illumination unit forms a diffuse illumination source and has an internally illuminated tunnel.
Claims20
An apparatus comprising:
- a camera configured to record a surface of a printed image, the printed image being movable relative to the apparatus;
- a first illumination unit of a first type configured to illuminate a first partial region of a region of the printed image capturable by the camera;
- a second illumination unit of a second type configured to illuminate a second partial region of the region capturable by the camera, wherein the first and second partial regions are arranged laterally next to each other;
- and
- an evaluation unit configured to process image information captured by the camera,
- wherein the first illumination unit differs from the second illumination unit,
- wherein the first illumination unit forms a diffuse illumination source and has an internally illuminated tunnel, and
- wherein the apparatus is configured to inspect printed images.
An apparatus comprising:
- a camera configured to record a surface of a printed image, the printed image being movable relative to the apparatus;
- a first illumination unit of a first type configured to illuminate a first partial region of a region of the printed image capturable by the camera;
- a second illumination unit of a second type configured to illuminate a second partial region of the region capturable by the camera,
- wherein the camera is configured to perform a surface inspection of the first and second partial regions at the same time;
- and
- an evaluation unit configured to process image information captured by the camera,
- wherein the first illumination unit differs from the second illumination unit,
- wherein the first illumination unit forms a diffuse illumination source and has an internally illuminated tunnel, and
- wherein the apparatus is configured to inspect printed images.

- a second illumination unit of a second type configured to illuminate a second partial region of the region capturable by the camera,
- wherein the first and second illumination units are located on the same side of the printed image as the camera;
- and
- an evaluation unit configured to process image information captured by the camera,
- wherein the first illumination unit differs from the second illumination unit,
- wherein the first illumination unit forms a diffuse illumination source and has an internally illuminated tunnel, and
- wherein the apparatus is configured to inspect printed images.
