We propose a one-dimensional integral imaging （1DII） display that consists of a display panel and a gradient-aperture parallax barrier. The gradient-aperture parallax barrier is symmetrical, and its slit widths gradually increase from both sides to the middle. The leftmost and rightmost slits are used to fix the viewing angle, whereas the other slits are used to increase the optical efficiency. A prototype of the proposed 1DII display is developed. Its optical efficiency is higher than that of the conventional display, but the viewin~ an^les are the same.
We propose an integral imaging system that uses three lens arrays,including two convex lens arrays and a concave lens array.Compared with the conventional integral imaging system,the proposed system can remarkably enhance the viewing angle.The maximum viewing angle can be enlarged to 48°,which is 4.8times wider than that of the conventional system.The principle of the proposed system is elucidated,and the experimental results are presented in this letter.
One-dimensional （ID） integral imaging based on parallax images＇ virtual reconstruction is proposed. The 1D integral imaging contains parallax images＇ capture process, parallax images＇ virtual reconstruction process, and ID elemental image array＇s generation process. A pixel mapping algorithm is deduced to implement the last two processes; a ID elemental image array is generated by the mapping of pixels on the parallax images obtained using a ID camera array. The proposed ID integral imaging can capture the ID elemental image array of a real three-dimensional （3D） scene.
