As a fundamental study on the objective evaluation of TV picture degradation by electromagnetic noise with visual physiological information, the electroencephalogram (EEG) activity was measured when a still TV picture was degraded by the burst noise whose rms and duration were changed. A degradation was subjectively evaluated by three-grade impairment scale of “Not Annoying”, “Slightly Annoying”, and “Annoying”. Measured EEGs were analyzed by an averaging technique. In the results, the amplitude of the event related potential P300 becomes larger when the subjects feel the noise “Annoying”.
