Reliability determination of camera fault detection tests
First Claim
1. A method for determining the reliability of a fault detection of a camera in a camera system, the camera system being arranged to perform a fault detection test to detect a fault of the camera based on data acquired by the camera, the method comprising:
- the camera system accessing criteria relating to environmental conditions external to the camera and affecting the reliability of the fault detection test;
the camera system receiving data relating to the environmental conditions at a time point;
the camera system checking whether the data relating to the environmental conditions complies with the criteria, thereby determining whether the fault detection test gives a reliable result at that time point; and
wherein the time point is a current time point, and the camera system performs the fault detection test only if the data regarding the environmental conditions complies with the criteria, wherein the data relating to the environmental conditions at a time point comprises data from a weather service, a pressure sensor, a motion sensor, a thermometer, a hygrometer, a photometer, or an image sensor.

Abstract
There is provided a method for determining the reliability of a fault detection of a camera in a camera system. According to the method data relating to environmental conditions are received (204) and compared to accessed (202) criteria relating to environmental conditions external to the camera and affecting the reliability of the fault detection test. If the received data complies with the criteria it is determined (206) that the fault detection test gives a reliable result. This is advantageous in that false fault detection tests may be identified.

8. A camera system comprising
a camera, and a processing unit for performing a fault detection test to detect a fault of the camera based on data acquired by the camera, and for determining the reliability of a fault detection of the camera, the processing unit being arranged to: -
access criteria relating to environmental conditions external to the camera and affecting the reliability of the fault detection test, receive data relating to the environmental conditions at a time point; and check whether the data relating to the environmental conditions at a time point complies with the criteria, the processing unit thereby being arranged to determine whether the fault detection test gives a reliable result at that time point, wherein the time point being a current time point, and the processing unit being arranged to perform the fault detection test only if the data regarding the environmental conditions complies with the criteria, wherein the data relating to the environmental conditions at a time point comprises data from a weather service, a pressure sensor, a motion sensor, a thermometer, a hygrometer, a photometer, or an image sensor.
