Optoelectronic device and method for adjusting brightness

摘要

The optoelectronic device (10) has a respective correction factor that is calculated for individual pixels or groups of pixels from a perspective transformation which converts geometries of an object plane (34) in the detection area (12) into geometries of the image plane (32). A calibration unit (26) is provided to determine the perspective transformation which converts a known absolute geometry of a calibration code into its detected geometry in the image. An independent claim is included for a method for brightness correction of pixel images of detection area.
