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.

An image free from interfering structures may be generated by means of a fiber bundle of several optical fibers, when for the system of fiber bundle and sensor imaging parameters are provided, which describe the geometrical characteristics of the intensity course generated by each individual optical fiber on the sensor. In image reconstruction, for each individual optical fiber an amplitude value and/or luminosity information may be generated by fitting a function of the amplitude value and the imaging parameters of the respective optical fiber to an intensity picture of the sensor, so that an optimum amplitude and/or luminosity value may be generated considering the geometrical imaging characteristics for each individual optical fiber.

In a method for extracting texture features from a multichannel image, which comprises a plurality of pixels, information of at least two channels of the image is combined for each of the plurality of pixels, and one or several texture features are determined from the combined pixel information.
