| Popis: | Current 3D (light field, LF) displays are capable to visualize the synthetic scenes simultaneously for different viewing positions. The user-perceived image changes smoothly within the field of view of such display. The global luminance level the of user-perceived image may change drastically with the viewing direction. This level is often used in image processing algorithms, such as tone mapping, in order to improve the image quality.In this paper, we suggest a method of evaluating the global luminance level for a particular type of horizontal-parallax light field display. This method requires only a set of projector images needed for the actual rendering, and can work in real-time. We test the visual performance of this method on a synthetic scene, and as a part of the conventional spatially-uniform tone mapping algorithm. |
