1. A method for analyzing image data of an image recorded by an image recording device for a vehicle, comprising:
- receiving, with a processor, the image data of the image via an image interface from the image recording device;
determining, by the processor, a brightness information of the image on the basis of the image data, taking an exposure characteristic of the image recording device into account;
setting, by the processor, a threshold value as a function of the brightness information;
determining, by the processor, an image structure of at least one region of the image; and
determining, by the processor, a blindness value for the image by comparing the image structure and the threshold value.

Abstract
In a method for analyzing an image of an image recording device for a vehicle, a piece of brightness information of the image is determined, taking an exposure characteristic of the image recording device into account, and a threshold value is set as a function of the piece of brightness information. An image structure of the image is furthermore determined, and a blindness value for the image is determined on the basis of the image structure, using the threshold value.
