Figure 4

Representative cases for evaluating color difference. The color difference () of the pixel values based on color spaces within the region of interest was analyzed to evaluate the visibility of each color image. Green line squares indicate region of interest in normal Barrett’s mucosa. White line squares indicate region of interest in gastric mucosa. Yellow line squares indicate region of interest in normal Barrett’s mucosa. BE: Barrett’s esophagus; EAC: esophageal adenocarcinoma; WLI: white light imaging; LCI: linked color imaging; BLI-b: blue laser imaging bright.
