In order to study the application of event-related potential (ERP) for performing picture quality evaluations, ERP was measured for both still and blurred pictures and were subjectively evaluated on a two-grade quality scale: “Good” and “Bad”. Also, a task for the evaluation was discussed. The results showed that similar large P300 amplitudes for both “Good” and “Bad” opinions appeared, which indicates that the use of opinions with two separate poles is not suitable.
