As Light Field Displays are becoming widely investigated among the research community and are recently entering consumer market, the Quality of Experience reached on such displays plays a more and more essential role in the determination of their value. Apart from the common characteristics of autostereoscopic displays, the level of zoom on a given spatial resolution also affects the subjective quality assessment of the visualized content. In this paper, we present a subjective study on the level of zoom for Light Field Displays. The perceptual effects of reconstruction based on Region of Interest are also taken into consideration due to their direct connection to zooming. Two independent experiments were carried out and they were completed by 20 test participants each, and the results of the subjective evaluation are detailed in this paper. Our work also addresses subjective quality assessment methodologies, as they influence the results obtained by such experiments.
