Abstract
An optoelectronic device () is provided having an image sensor () for generating pixel images of a detection area () and a brightness correction unit () configured to modify brightness values of the pixels with a correction factor (H) to obtain a more homogeneously illuminated image. A respective correction factor (H) is calculated for individual pixels or groups of pixels from a perspective transformation (M) which converts geometries of an object plane () in the detection area () into geometries of the image plane ().
