Abstract (en)

[origin: WO2009050106A1] The invention relates to a test device (11) for testing the validity of display signals relating to a predetermined image. Said test device comprises a device for acquiring image data (28) from the display signals, a device for determining a test value of the image data, and a comparative unit (27) for comparing the test value (28) obtained with a stored test value (26) that relates to the image. The display signals are found to be valid if the two test values are identical.
