Definitions
- the present invention is based primarily on the problem of defects that are mechanically connected to the matrix of optoelectronic sensors, such as scratches in the sensor coating, dust particles on the matrix, defective pixels or sensors and / or Glass defects, scratches, dust etc. in or on the protective glass positioned and connected in front of the sensor and / or eg IR cut filter etc. can be detected in a simple and reliable manner and thus create the basis for a corresponding image correction.
- the comparison result ⁇ at the output of the comparison unit 9, which corresponds to a matrix of comparison result signals is preferably revised. This takes place on an image processing arithmetic unit 12.
- the correspondingly processed, corrected electronic image Bi k results in a memory unit 14.
