Abstract
In a method and apparatus for evaluating image segments for a correspondence calculation, an image signal is received from an image sensor and is evaluated in order to determine the extent to which, for a selected region of the image sensor, noise caused by the image sensor is present; and a resultant evaluation parameter, for an image segment of an image acquired by the image sensor, which describes whether the image segment is suitable for a correspondence calculation, is ascertained. The image segment corresponding to the selected region of the image sensor and the resultant evaluation parameter are ascertained based on the determined extent of the noise.
