To study the application of event-related potential (ERP) for performing picture quality evaluation, ERP was measured for both still and blurred pictures that were subjectively evaluated. A comparison method with quality scales for each “better” and “worse” opinion was used. The results showed that the largest P300 amplitude for each “much better” and “much worse” opinion appeared, and the P300 amplitude and latency varied depending on the opinions in each quality scale, which indicates one of the methods for picture quality evaluation using ERP.
