Abstract
Image quality has consistently been an important issue in the 3D display industries, given the fact that better image quality could improve entertainment experience for viewers while watching dynamic films or improve operating efficiency in military or medial use while watching static 3D images. Therefore, this study aimed to investigate the effect of different factors on static and dynamic film image quality. This study consisted of two stages. In the first stage, a Taguchi method was used to investigate display luminance, ambient illumination, range of disparity, brightness contrast ratio, and viewing time effect on static image quality and depth perception measurement. In the second stage of experiment, we examined the effect of different objects, moving velocities and disparity locations on dynamic film’s judgment of ended disparity and subjective image quality evaluation. The result for static image showed that the optimal combination depended on the type of dependent variable. For instance, in order to have the best image quality, the ambient illumination needed to be at 103 lux. However, to obtain the best depth perception, the range of disparity and the viewing time needed to be at 0.85o and 90 minutes respectively. For dynamic film, the structure of the object should be simpler and the starting disparity location should be located behind the display to obtain the best subjective image quality. The judgment of ended disparity could be a stopping point for the film to prevent the film’s image quality to degrade under different moving velocities and disparity locations. In conclusion, disparity is a vital factor that affects the perception of depth. When the static image is located behind the display with longer viewing time and the dynamic films starting location is behind the display, the depth perception would be judged as deeper.
