Optimal white-point setting for natural images considering content dependency

Image quality is one of the decisive factors for consumers when buying electronic display. White point is an important aspect affecting image quality evaluation. The paper investigated the preferred white-point setting for natural images considering content dependency. Images were generated by changing white-point from original image to different extent via image processing. The averaged preferred white point setting is close to previous research. In addition, the preferred white point settings are also investigated for desaturated images and blurred ones. The preferred white point for desaturated images is a little yellowish compared with those for original images. However, the preferred white point is not changed statistically when images are blurred.
