An illumination apparatus for an image sensor at the distal end of an endoscope includes an illumination carrier and a plurality of micro LEDs each including a main surface from which the emission is made, with a maximum lateral dilatation of less than 500 &#x3bc;m. The illumination carrier is associated with the distal end of the endoscope, and the plurality of micro LEDs are arranged on the illumination carrier such that with electrical excitation, the environment of the distal end of the endoscope is at least in some portions illuminated.

A method for detecting an object on an image representable by picture elements includes: 'determining first and second adaptive thresholds for picture elements of the image, depending on an average intensity in a region around the respective picture element', 'determining partial objects of picture elements of a first type that are obtained based on a comparison with the first adaptive threshold', &#x201c;determining picture elements of a second type that are obtained based on a comparison with the second adaptive threshold&#x201d; and &#x201c;combining a first and a second one of the partial objects to an extended partial object by picture elements of the second type, when a minimum distance exists between the first and the second of the partial objects, wherein the object to be detected can be described by a sum of the partial objects of picture elements of the first type and/or the obtained extended partial objects&#x201d;.

The invention relates to a method and device for recognizing a coin by using the embossed pattern characteristics thereof. For this purpose, the inventive method comprises in spreading the characteristics of the picture, in reducing said characteristics by reducing said picture and in transforming it by polar transformation, in comparing the transformed picture with a plurality of reference patterns according to a first simplified criterion, in creating a list of the reference patterns, in sorting them according to the similarity thereof with the transformed picture and in comparing the transformed picture with the reference patterns contained in the list according to the sorting thereof upon a second exact criterion.
