Digital camera and method for testing the function of a digital camera

摘要

The invention refers to a digital camera 1 which can be used in a motion sensor 4. In order to be able to test the function of the camera, a light source 3 is provided which irradiates at least a part of the sensing matrix 2. The processor device 5 of the camera judges whether the output signal of the sensing matrix 2 corresponds correctly to the light which has irradiated the sensing matrix 2. Various test methods are disclosed, such as using varying wavelengths, ON/OFF-modulation, dependence on shutter time and illumination of various regions of the sensing matrix 2.
