An apparent 3-D image can be perceived from only two 2-D images displayed at different depths, when an observer views them from the direction in which they are overlapped. The two 2-D images are created from an original 2-D image by dividing its luminance according to independently obtained depth information. Subjective test results show that (1) an(More)
We have developed a high-frame-rate LED display. Full-color images with high brightness are refreshed at 480 frames per second. In order to transmit such a high framerate signal via conventional 120-Hz DVI, we have introduced a spatiotemporal mapping for its signal input. Four adjacent pixels in each frame in DIV signal are converted into successive four(More)
SUMMARY We estimated the dependence of the perceived depth on lu-minance ratio by increasing the distance between the front and rear planes of a depth-fused 3-D (DFD) display. When the distance is great, the perceived depth has the tendency of nonlinear dependence on luminance ratio , which is very different from the almost linear dependence in a(More)
— We propose methods to control viewing zones of large screen consisted of full-color LED panel. Large parallax barriers have been developed for public 3-D display. By changing pixel arrangements, locations and number of perspectives can be reconstructed. Response of viewer's position caused by a shift of viewing was detected to evaluate the design of(More)
We solve a serious problem affecting depth-fused three-dimensional (3-D) (DFD) displays wherein the maximum depth between front and rear planes is limited, because depth fusing from front and rear images into one 3-D image becomes impossible. We also propose a perception model for this deep DFD display. When the distance between planes is large, the(More)
